Abstract: PURPOSE: To assess the role of radiotherapy (RT) in women with Stage IIIC endometrial cancer. METHODS AND MATERIALS: The 17-registry Survival, Epidemiology, and End Results (SEER) database was searched for patients with lymph node-positive non-Stage IV epithelial endometrial cancer diagnosed and treated between 1988 and 1998. Two subgroups were identified: those with organ-confined Stage IIIC endometrial cancer and those with Stage IIIC endometrial cancer with direct extension of the primary tumor. RT was coded as external beam RT (EBRT) or brachytherapy (BT). Observed survival (OS) was reported with a minimum of 5 years of follow-up; the survival curves were compared using the log-rank test. RESULTS: The therapy data revealed 611 women with Stage IIIC endometrial cancer during this period. Of these women, 51% were treated with adjuvant EBRT, 21% with EBRT and BT, and 28% with no additional RT (NAT). Of the 611 patients, 293 had organ-confined Stage IIIC endometrial cancer and 318 patients had Stage IIIC endometrial cancer with direct extension of the primary tumor. The 5-year OS rate for all patients was 40% with NAT, 56% after EBRT, and 64% after EBRT/BT. Adjuvant RT improved survival compared with NAT (p <0.001). In patients with organ-confined Stage IIIC endometrial cancer, the 5-year OS rate was 50% for NAT, 64% for EBRT, and 67% for EBRT/BT. Again, adjuvant RT contributed to improved survival compared with NAT (p = 0.02). In patients with Stage IIIC endometrial cancer and direct tumor extension, the 5-year OS rate was 34% for NAT, 47% for EBRT, and 63% for EBRT/BT. RT improved OS compared with NAT (p <0.001). Also, in this high-risk subgroup, adding BT to EBRT was superior to EBRT alone (p = 0.002). CONCLUSION: Women with Stage IIIC endometrial cancer receiving adjuvant EBRT and EBRT/BT had improved OS compared with patients receiving NAT. When direct extension of the primary tumor was present, the addition of BT to EBRT was even more beneficial.
Abstract: PURPOSE: Based on the activity and tolerability of liposomal doxorubicin in platinum- and paclitaxel-resistant ovarian carcinoma, we conducted a phase I trial of pegylated liposomal doxorubicin with paclitaxel and carboplatin to determine the maximum tolerated dose (MTD) in chemotherapy naive ovarian, peritoneal and tubal carcinoma patients. METHODS: Three schedules were studied: paclitaxel, carboplatin and pegylated liposomal doxorubicin every 28 days; paclitaxel and carboplatin every 21 days with liposomal doxorubicin every 42 days; and weekly paclitaxel, carboplatin (AUC=5) every 21 days and liposomal doxorubicin every 42 days. The paclitaxel dose was 175 mg/m(2) over 3 h on an every 3-4 week schedule and 60 mg/m(2) when administered weekly. Based on the frequency of neutropenic sepsis, grade 4 thrombocytopenia and > or =grade 3 non-hematologic toxicity, the starting dose of liposomal doxorubicin of 20 mg/m(2) was escalated to determine the MTD. RESULTS: A total of 210 (21-day) cycles were administered to 37 patients. Dose-limiting toxicity (DLT) occurred when liposomal doxorubicin was administered at 40 mg/m(2). Because of treatment-related delays resulting in decreased paclitaxel/carboplatin dose intensity, administration was modified to be given every 21 days, with liposomal doxorubicin given every 42 days. Since neutropenia was the DLT of this schedule, the schema was further modified to administer paclitaxel weekly; however, weekly administration was inconsistent because of toxicity. CONCLUSION: Paclitaxel 175 mg/m(2), carboplatin (AUC=5) and pegylated liposomal doxorubicin 30 mg/m(2) are tolerable without supportive therapy. The usual dose intensity of paclitaxel/carboplatin was maintained by administering liposomal doxorubicin every other cycle.
Abstract: Numerous molecular biomarkers have been suggested for early detection of cervical cancer, but their usefulness in routinely collected exfoliated cells remains uncertain. We used quantitative reverse transcription-PCR to evaluate expression of 40 candidate genes as markers for high-grade cervical intraepithelial neoplasia (CIN) in exfoliated cervical cells collected at the time of colposcopy. Samples from the 93 women with CIN3 or cancer were compared with those from 186 women without disease matched (1:2) for age, race, and high-risk human papillomavirus status. Normalized threshold cycles (C(t)) for each gene were analyzed by receiver operating characteristics to determine their diagnostic performance in a split sample validation approach. Six markers were confirmed by an area under the curve >0.6 in both sample sets: claudin 1 (0.75), minichromosome maintenance deficient 5 (0.71) and 7 (0.64), cell division cycle 6 homologue (0.71), antigen identified by monoclonal antibody Ki-67 (0.66), and SHC SH2-domain binding protein 1 (0.61). The sensitivity for individual markers was relatively low and a combination of five genes to a panel resulted in 60% sensitivity with 76% specificity, not positively increasing this performance. Although the results did not indicate superiority of RNA markers for cervical cancer screening, their performance in detecting disease in women referred for colposcopy suggests that the genes and pathways they highlight could be useful in alternative detection formats or in combination with other screening indicators.
Abstract: BACKGROUND: Embryonal rhabdomyosarcoma is a rare sarcoma which characteristically occurs in non genitourinary sites in children. CASE: We present a case of uterine embryonal rhabdomyosarcoma in a postmenopausal patient who presented with increasing abdominal girth, early satiety, weight loss, and pelvic pain. CONCLUSION: Embryonal rhabdomyosarcoma does not commonly originate from the uterine corpus, and it is rarely seen in postmenopausal patients. A review of the literature confirms the unique nature of this case.
Abstract: Disabled-2 (Dab2) is a phosphoprotein involved in cellular signal transduction and endocytic trafficking. The expression of Dab2 is frequently lost or suppressed in several epithelial tumors, and studies of its cellular function and growth suppressive activity when re-expressed in cancer cells led to the suggestion that Dab2 is a tumor suppressor. A role for Dab2 in epithelial cell positioning organization was derived from study of knockout mice: homozygous deletion of dab2 results in early embryonic lethality due to the disorganization of the primitive endoderm, the first epithelium in early embryos. We now report that dab2 heterozygous mice develop uterine hyperplasia and ovarian preneoplastic morphological changes at a high frequency. Crossing into a p53(-/-) background unexpectedly produced few female dab2(+/-):p53(-/-) mice, while the male dab2(+/-):p53(-/-) were born at the expected Mendelian frequency. The tumor-prone phenotype of dab2(+/-) mice provides additional support for a role of human Dab2 as a tumor suppressor, and the sex-biased embryonic lethality suggests a genetic interaction between p53 and dab2 genes in female mice.
Abstract: While infection with high-risk HPV is the most important risk factor for cervical cancer, HPV alone is insufficient. Our purpose was to identify viral and epidemiologic factors associated with cervical disease in HPV-16 DNA-positive women referred to colposcopy. We used a standardized interview to collect epidemiologic data from consenting women. Total nucleic acids from exfoliated cervical cells were used for all viral assays (HPV detection and typing using L1 consensus PCR with line probe hybridization, variant classification by sequencing, viral load and transcript copy determination by quantitative PCR and transcript pattern by nested RT-PCR). Cervical disease was based on colposcopic biopsy. Logistic regression was used to calculate ORs with 95% CIs. There were 115 HPV-16 positive women among 839 enrollees. By univariate analyses, age >25 years (OR = 3.05, 95% CI 1.20-7.76), smoking (OR = 3.0, 95% CI 1.19-7.56), high viral load (OR = 5.27, 95% CI 2.05-13.60), detection of both E6 and E6*I transcripts (OR = 10.0, 95% CI 2.1-47.58) and high transcript copies (OR = 5.56, 95% CI 2.05-13.60) were significant risk factors for CIN III with reference to No CIN/CIN I. Less than a third of the women (31.5%) had prototype HPV-16 detected, and variants showed no association with disease, viral load or transcription. Viral DNA and transcript copies were highly correlated, and the ratio of transcript copies to DNA copies was not changed with disease status. While viral load, transcript copies and transcript pattern were statistically associated with CIN III, none of these measures effectively discriminated between HPV-16 women with disease requiring treatment and those who could be followed. Cellular proliferation and differentiation pathways affected by HPV should be investigated as biomarkers for cervical cancer screening.
Abstract: The introduction of cytokine antibody arrays has added a new approach for investigators to simultaneously measure multiple cytokine levels in biological samples. Several different platforms have been developed. The ability to measure hundreds of cytokine levels with high specificity and sensitivity within a very limited amount of samples is a powerful tool. Many investigators worldwide have applied this novel technology in their biomedical research, particularly in drug discovery. Undoubtedly, the technology will continue to be improved and the application increased in the next several years.
Abstract: OBJECTIVE: To analyze the impact of patient and organizational characteristics on surgical treatment patterns for patients with uterine fibroids. METHODS: Unadjusted means and percentages were calculated from a population-based inpatient sample (HCUPNIS). Multiple logistic regression analysis was used to estimate the prevalence odds ratios for the association of uterine fibroid treatments and covariates of interest. RESULTS: More than 1.2 million patients with a primary diagnosis of uterine fibroids were treated from 1998 to 2002. Of these, 84.4% received a hysterectomy and 12.3% received a myomectomy. Total abdominal hysterectomy was the most common procedure. The number of supracervical hysterectomies increased 18.1% over the five-year period. Black women and Asians/Pacific Islanders were more likely than white women to receive a myomectomy. All types of hysterectomies were more common in Medicaid patients compared with private/HMO patients. With the exception of patients in ZIP codes with a median income of <$25,000 per year, an inverse relationship was identified between income and hysterectomy rates. CONCLUSIONS: The management of uterine fibroids appears to differ across a variety of socioeconomic factors and institutional characteristics. This study suggests that additional research should be conducted to assess the impact of nonclinical factors on treatment decisions for patients with uterine fibroids.
Abstract: PURPOSE: The purpose of this study is to develop a high-throughput approach to detect protein expression from hundreds and thousands of samples and to apply this technology to profile circulating angiogenic factor protein levels in patients with gynecological tumors. EXPERIMENTAL DESIGN: Analytes containing a mixture of protein are immobilized onto antibody-coated surface of support in array format. The presence of protein in analytes is detected with biotin-labeled antibody coupled with an enhanced chemiluminescence or fluorescence detection system. The exact amount of protein can be quantitatively measured. The expression levels of five angiogenic factors (angiogenin, interleukin 8, vascular endothelial growth factor, platelet-derived growth factor, and epidermal growth factor) from 157 samples were quantitatively measured using this novel protein array technology and were statistically analyzed. The expression patterns of angiogenic factors were analyzed using two-way hierarchical cluster analysis approach. RESULTS: A novel protein array technology, which can simultaneously and quantitatively measure few protein levels from hundreds and thousands of samples was developed. Only minute amounts of sample are required for the assay. This approach also features high sensitivity and specificity. Using this novel protein array approach, we analyzed the plasma expression levels of five angiogenic factors in 137 patients diagnosed with a tumor and 20 controls. Statistical analysis reveals different expression levels of angiogenic factors between patients and controls. Cluster analysis suggests a possible classification of normal subjects from patients. CONCLUSIONS: Enhanced protein profiling arrays provide a high-throughput and sensitive system to detect one or few protein from hundreds and thousands of samples. Such an approach should have broad application in biomedical discovery.
Abstract: PURPOSE: To evaluate the feasibility, toxicity, and efficacy of single-agent monoclonal antibody therapy targeting the human epidermal growth factor receptor 2 (HER2)/neu receptor in ovarian and primary peritoneal carcinoma. PATIENTS AND METHODS: Eligible patients had measurable persistent or recurrent epithelial ovarian or primary peritoneal carcinoma with 2+ or 3+ HER2 overexpression documented by immunohistochemistry. Intravenous trastuzumab was administered initially at a dose of 4 mg/kg, then weekly at 2 mg/kg. Patients without progressive disease or excessive toxicity could continue treatment indefinitely. Those with stable or responding disease at 8 weeks were offered treatment at a higher weekly dose (4 mg/kg) at time of progression. Patient sera were analyzed for the presence of the soluble extracellular domain of HER2, host antibodies against trastuzumab, and trastuzumab pharmacokinetics. RESULTS: A total of 837 tumor samples were screened for HER2 expression, and 95 patients (11.4%) exhibited the requisite 2+/3+ expression level. Forty-five patients, all of whom received prior chemotherapy, were entered, and 41 were deemed eligible and assessable. There were only mild expected toxicities and no treatment-related deaths. Although an elevated level of the soluble extracellular domain of HER2 was detected in eight of 24 patients, serum HER2 was not associated with clinical outcome. There was no evidence of host antitrastuzumab antibody formation. Serum concentrations of trastuzumab gradually increased with continued therapy. An overall response rate of 7.3% included one complete and two partial responses. Median treatment duration was 8 weeks (range, 2 to 104 weeks), and median progression-free interval was 2.0 months. CONCLUSION: The clinical value of single-agent trastuzumab in recurrent ovarian cancer is limited by the low frequency of HER2 overexpression and low rate of objective response among patients with HER2 overexpression.
Abstract: Glycodelin, an immunosuppressive protein with contraceptive properties, is synthesized by a variety of tissues and cell types. The ability of reproductive tissues to synthesize glycodelin is of major interest in pregnancy and disease conditions. We studied glycodelin levels in subjects with malignant gynecological tumors and in control subjects. Using a polyclonal glycodelin antibody against the synthetic glycodelin peptide sequence, an enzyme-linked immunosorbent assay (ELISA) was devised to measure plasma glycodelin levels. The assay detected as much as 5 ng/ml of glycodelin. There was a significant increase in plasma glycodelin levels in endometrial > ovarian > cervical cancer subjects when compared to those of controls. Strong expression of mRNA and protein were found in the ovarian and endometrial tumor tissues. Given glycodelin's immunosuppressive abilities, increased level of glycodelin may facilitate tumor growth in gynecological malignancies.
Abstract: Angiogenesis plays an important role in neovascularization in tumors. Glycodelin, a hormone-responsive protein, has been detected in tumors of reproductive organs and is found in high levels in the plasma of subjects with gynecological malignancies. Glycodelin is also found in the endothelial cells of the umbilical cord and in the blood vessels of tumors. In this study, we tested whether glycodelin-rich amniotic fluid and a synthetic peptide derived from the sequence of glycodelin peptide (Gp) might promote angiogenic response by examining the migration and tube formation in human umbilical cord vein endothelial cells (HUVECs). Increased migration and tube formation of HUVECs were found in the presence of amniotic fluid and Gp, and this increase was blocked by antibody to Gp and by an anti-vascular endothelial growth factor (VEGF) antibody, suggesting that the angiogenic effects of glycodelin might be mediated by VEGF. The results also showed that Gp significantly increased the release of VEGF protein and mRNA expression in HUVECs, RL-95 (human endometrial carcinoma cells), OVCAR-3 (human ovarian adenocarcinoma cells), EM42 (human endometrial epithelial cells), THP-1 (human monocyte), and MCF-7 and MDA-MB-231 (human breast adenocarcinoma cells) cell lines. VEGF receptor Fit-1 mRNA expression in HUVECs was also increased in the presence of Gp. These findings, together with the suggestion from the literature that glycodelin may have immunosuppressive properties, suggest that glycodelin might play an important role in neovascularization during embryogenesis and tumor development.
Abstract: Cervical carcinoma is prevented easily with proper screening. Unfortunately, many women in industrialized countries continue to have poor access to adequate medical care. In many third-world countries, cervical cancer is one of the top malignancies diagnosed. Screening should be provided for all women to prevent or diagnose cervical cancer at an early, treatable stage.
Abstract: PURPOSE: Given the activity of prolonged oral etoposide in platinum and paclitaxel-resistant ovarian carcinoma, a phase I trial was conducted that combined increasing days of oral etoposide therapy with paclitaxel and carboplatin in chemotherapy-naive patients with ovarian peritoneal and tubal carcinoma to establish a maximum-tolerated dose (MTD) of this combination. PATIENTS AND METHODS: Paclitaxel at 175 mg/m(2) given over 3 hours and carboplatin at an area under the curve of 5 were administered on day 1 followed by oral etoposide 50 mg/m(2)/d beginning on day 2. The number of days of etoposide therapy was escalated on the basis of toxicity. Toxicity end points included neutropenic sepsis, grade 4 thrombocytopenia, or grade 3 neutropenia or thrombocytopenia during etoposide administration. Cycles were repeated every 21 days for a maximum of six courses. Due to hematologic toxicity, the duration of the paclitaxel infusion was decreased to 1 hour for a second stage of accrual. RESULTS: Of 52 patients studied, 29 were in the first stage of accrual. Dose-limiting toxicity occurred with 8 days of oral etoposide, making the MTD six days of therapy. Twenty-three patients were entered into the second stage of accrual. Dose-limiting toxicity occurred at 12 days of oral etoposide, making the MTD 10 days of therapy. Three patients developed acute myeloid leukemia 16, 27, and 35 months after receiving a cumulative dose of 200 mg/m(2), 1,200 mg/m(2), and 2,400 mg/m(2), respectively. CONCLUSION: One-hour paclitaxel, carboplatin, and oral etoposide at 50 mg/m(2)/d for 10 days is tolerable without supportive therapy. The leukemogenic potential is cause for concern and precludes its use in chemotherapy-naive ovarian carcinoma.
Abstract: Epithelial ovarian cancer (EOC) continues to be an academically challenging and clinically problematic disease. Even with recent advances, the overall 5-year survival is still 31% to 42% in various studies. Deaths from EOC outnumber those due to cervical, vulvar, and endometrial carcinomas combined. Screening for EOC has shown limited success in early detection. The Pap smear is not a dependable tool in EOC screening, though at times it can be the first evidence of ovarian disease. We report a case of EOC that was diagnosed during evaluation of an abnormal Pap smear. On completion of evaluation, stage IIIA endometrioid-type adenocarcinoma of the ovary was diagnosed. Occult EOC should be considered in patients with abnormal findings on cervical cytology after cervical and uterine carcinomas are ruled out.
Abstract: OBJECTIVE: To explore whether HIV serostatus (HIV-1, HIV-2, and dual (HIV-D) reactivity) and CD4 cell count affect human papillomavirus (HPV) in two groups of women from Côte d'Ivoire. METHODS: We conducted a cross sectional study of two groups of women. One group had low numbers of lifetime sex partners (maternal women, n = 258) and were enrolled based on HIV serostatus. The other group had high numbers of sex partners (female sex workers, n = 278) and all consenting self identified sex workers were admitted to this study. We collected epidemiological and clinical data, and cervicovaginal lavage for HPV testing. RESULTS: The groups had different distributions of HIV seroreactivity, but the rates of HPV DNA detection were similar. Most of the HPV DNAs detected in both groups were high risk types. A strong association of high risk HPV DNA and HIV-1 seropositivity was found in both maternal women (adjusted odds ratio (OR) 7.5 (95% CI 3.2-17.4)) and in sex workers (OR 5.0 (2.1-12.0)). The maternal group also showed an association of high risk HPV DNA detection with HIV-2 (OR 3.7 (1.6-8.5)) and HIV-D (OR 12.7 (4.3-37.5)) that was not observed in the sex workers. In addition, the association of high risk HPV DNA with HIV-1 in the maternal group was independent of low CD4 cell count, while in the sex workers the association depended on CD4 cell counts < or = 500 x 10(6)/l. CONCLUSIONS: We found that an association between HPV and HIV varied depending on the sexual behaviour and CD4 cell count of the population examined.
Abstract: OBJECTIVE: To explore whether HIV types 1 and 2 and CD4 cell count affect cervical neoplasia independent of human papillomavirus (HPV) in women with high or low numbers of sexual partners residing in Abidjan, Côte d'Ivoire. METHODS: The study population and methods are described in the companion paper. Additional methods include a Papanicolaou smear for cytological diagnosis and statistical analysis. RESULTS: In maternal women, both HIV-1 and high risk HPV were significant independent risk factors for squamous intraepithelial lesions (SIL) (adjusted odds ratio (OR) 11.0 (95% CI 1.1-112) and 5.4 (1.5-18.8), respectively). Only high levels of HPV DNA in the lavage were associated with SIL (OR 13.2 (3.6-47.8)) in the maternal group. In female sex workers, high risk HPV was significantly associated with SIL (OR 23.7 (4.4-126)); HIV seropositivity was not. Any positive level (high or low amounts) of HPV DNA was significantly associated with SIL in sex workers (ORs 15.9 (3.3-76) and 12.7 (3.6-44), respectively). There was no association of SIL with CD4 cell counts < or = 500 x 10(6)/l in HIV seropositive women from either group. CONCLUSION: HPV or HIV-1 infection independently affect cervical neoplasia in women with low numbers of sex partners.
Abstract: OBJECTIVE: Our goal was determine the correlation between serum colony stimulating factor-1 levels, cervical human papillomavirus infection, and dysplasia. STUDY DESIGN: Serum samples were obtained from control subjects from the United States and from a group of Panamanian women. Members of the latter group fell into 3 categories: those who serve as Panamanian control subjects and who test negative for human papillomavirus (n = 10); those who are high risk by history and test positive for human papillomavirus types 16/18 and 30s (n = 10); and those with the same high-risk history with biopsy-proven cervical intraepithelial neoplasia (n = 8). Serum colony-stimulating factor-1 levels were determined using enzyme-linked immunosorbent assay. Data were analyzed with the Student-Newman-Keuls and t tests. RESULTS: Mean serum colony-stimulating factor-1 levels of patients with a positive test result for human papillomavirus (1166 +/- 949 pg/mL) and cervical intraepithelial neoplasia (1295 +/- 314 pg/mL) were higher than those of control subjects from the United States (584 +/- 237 pg/mL) and those of Panamanian control subjects (520 +/- 229 pg/mL). Statistical analysis revealed the concentration of colony-stimulating factor in patients with positive test results for human papillomavirus or cervical intraepithelial neoplasia were significantly higher than in control groups. In addition, combining patients with human papillomavirus with those who have cervical intraepithelial neoplasia results in a group that has significantly higher colony-stimulating factor levels compared with control subjects. CONCLUSIONS: Both high-grade cervical dysplasia and high-risk human papillomavirus infection are associated with higher mean serum colony-stimulating factor levels, suggesting a possible role for colony-stimulating factor-1 in cervical neoplasia. Further studies are needed to understand the mechanism of colony- stimulating factor activation in human papillomavirus infection. This may assist in designing therapeutic approaches for the management of this disease.
Abstract: This study reviewed a high-risk population of inner-city women with FIGO (International Federation of Gynecologists and Obstetricians) stage Ib cervical cancer diagnosed and treated at a single institution between 1986 and 1993. The patient age at diagnosis averaged 49 years, and most of the patients were black (83%). Squamous carcinomas predominated (75%). Radiotherapy was the most frequent treatment modality (49%), followed by surgery (38%) and combined radiation/surgery (13%). The Kaplan-Meier estimated 4-year survival for all patients completing treatment was 81%. Increased survival was significantly associated with therapy. The Kaplan-Meier estimated survival at 26 months (the time of the last death in radiotherapy patients) was 66% for radiotherapy patients and 100% for those treated with surgery. Radiotherapy patients differed from surgery patients in age, tumor size, and pelvic lymph node status, indicating that treatment selection bias could explain the observed difference in survival. Age, race, histology, and cervical lesion size were not significantly associated with survival.
Abstract: PURPOSE: To test the hypothesis that prolonged infusion of paclitaxel (96 hours) might overcome resistance to shorter infusion schedules (3 or 24 hours) in ovarian cancer. PATIENTS AND METHODS: A total of 30 patients with advanced ovarian cancer (24 patients), primary carcinoma of the peritoneum (four patients), or fallopian tube cancer (two patients) who previously had received paclitaxel administered on either a 3-hour or 24-hour schedule were treated with the agent delivered as a 96-hour infusion (30 to 35 mg/m2/d x 4 days) on an every 3-week program. RESULTS: Although the regimen generally was well tolerated, no objective responses were observed. CONCLUSION: In patients with ovarian cancer who have shown resistance to shorter paclitaxel infusion schedules, ninety-six hour infusional paclitaxel is an inactive treatment strategy. This makes it less likely that protracted infusion of paclitaxel will improve outcome when used as part of primary therapy of ovarian cancer. An ongoing randomized study will answer that question.
Abstract: This case report describes a 31-year-old woman at 8 weeks' gestation with large arteriovenous malformation of the uterus involving bilateral uterine and ovarian arteries. She had a history of multiple pregnancy losses, as well as spontaneous copious vaginal hemorrhage. The patient underwent an embolization procedure followed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. The uterus was very small (30 g) despite its gravid status, and the overall microscopic findings indicated Müllerian system hypoplasia in addition to vascular malformation.
Abstract: BACKGROUND: Pelvic inflammatory disease (PID) is a common gynecologic disorder. One known complication of PID is tubo-ovarian abscess (TOA) formation. The predominant theory on TOA formation postulates that an ascending infection from the cervix through the uterus to the fallopian tubes and ovaries results in abscess formation. Other theories include seeding via a hematogenous infection, diverticular disease, and appendicitis. CASE: A 39-year-old female patient with abdominal pain was referred to our institution and was found to have a pelvic mass. After a thorough evaluation, surgical exploration revealed the presence of TOA. No evidence of gastrointestinal disease was present. The patient's history was significant for an uncomplicated total abdominal hysterectomy for benign disease of the uterus four years prior. Abscess cultures grew Streptococcus intermedius. CONCLUSION: This case reports the rare occurrence of TOA in a patient who had undergone an abdominal hysterectomy four years prior to presentation. If the patient reports a surgical history of prior hysterectomy, TOA is often stricken from consideration. Although unlikely, adnexal abscess formation should be considered in the differential diagnosis of a patient with abdominal pain and a pelvic mass, even with a remote history of hysterectomy.
Abstract: We enrolled 85 patients with invasive cervical cancer and collected cervicovaginal lavage samples at each clinical visit for diagnosis, staging, treatment, and follow-up. Lavage samples were tested by L1 consensus polymerase chain reaction for human papillomavirus (HPV). Results were compared with HPV demonstrated in tumor tissue and the clinical status at time of sample collection. Sensitivity and specificity of the lavage for detection of tumor HPV, determined on the basis of results of tests on lavage samples collected prior to therapy, were found to be 56% and 76.9%, respectively. The proportion of lavage samples detecting tumor HPV decreased significantly with treatment, from 0.54 at diagnosis to 0.03 at complete response (P < .001). Local treatment failure was associated with increased detection of tumor HPV; however, no samples were positive prior to clinically detected treatment failure. These results suggest that cervicovaginal lavage is not an effective sampling method for epidemiological analysis of HPV in cervical tumors.
Abstract: PURPOSE: A phase I and pharmacologic study to evaluate the feasibility of administering paclitaxel (PTX) in combination with topotecan (TPT) without and with granulocyte colony-stimulating factor (G-CSF) in women with recurrent or refractory ovarian cancer. PATIENTS AND METHODS: TPT was administered as a 30-minute infusion daily for 5 days and PTX was given as a 24-hour infusion (PTX-24) either before TPT on day 1 or after TPT on day 5. Each patient received both schedules on an alternating basis every 3 weeks. Sequential dose escalation of TPT or PTX-24 without and with G-CSF resulted in five dosage permutations of TPT/PTX (mg/ m2): 0.75/135 without G-CSF and 0.75/135, 1.25/135, 1.50/135, and 1.25/170 with G-CSF. RESULTS: Twenty-two patients received 109 courses of therapy. Dose-limiting myelosuppression consistently occurred at the first TPT/PTX-24 dose level (0.75/135 mg/m2) in the absence of G-CSF support. Although the addition of G-CSF resulted in reduced rates of complicated neutropenia, the incidences of dose-limiting neutropenia and thrombocytopenia were unacceptably high after the doses of either TPT or PTX-24 were increased. Paired analysis showed similar hematologic toxicities between the two sequences of drug administration. The pharmacologic behavior of both TPT and PTX-24 was not altered by drug sequencing. Major antitumor responses occurred in 40% of patients with measurable and assessable disease, including 45% and 9% of patients with potentially cisplatin-sensitive and -resistant tumors, respectively. CONCLUSION: The recommended doses of TPT on a daily times-five schedule combined with PTX-24 in these patients were 0.75 mg/m2/d and 135 mg/m2, respectively, with G-CSF support. Although this dose of PTX has significant single-agent activity in ovarian cancer, the dose of TPT is much lower than the TPT dose at which single-agent activity has been observed. Due to the inability to administer near relevant single-agent doses of both drugs in combination, as well as the requirement for G-CSF support, further evaluations of this regimen in women with refractory or recurrent ovarian cancer are necessary before it can be recommended for previously treated patients in this setting.
Abstract: Pseudomyxoma peritonei is a condition characterized by the production of large amounts of mucopolysaccharide by a neoplastic epithelium. Although surgical debulking and removal of the mucinous ascites may be attempted, complete removal of the material is often impossible. Intraperitoneal lavage with 10% dextrose in water (D10W) has been advocated to prevent reaccumulation of the mucus and complications such as bowel obstruction requiring repeat laparotomy. We describe a patient undergoing operation for a large abdominopelvic mass. At laparotomy, a mucinous cystadenocarcinoma of the ovary was found with a great deal of tenacious, mucinous ascites and peritoneal implants. In an effort to more efficiently remove the mucus and prevent subsequent reaccumulation, intraperitoneal irrigation with 10% dextrose in water (D10W) was performed. The patient, who gave no history of prior glucose intolerance, was soon thereafter found to be profoundly hyperglycemic (serum glucose >500 mg/dl). She was treated with insulin and recovered without evident sequelae. Practitioners should be aware of this potentially dangerous complication associated with intraperitoneal dextrose instillation.
Abstract: BACKGROUND: Basal cell carcinoma is the most common malignant tumor of the skin, with approximately 400,000 new cases yearly in the United States. Basal cell carcinomas account for 2-3% of all vulvar malignancies. CASES: Four patients presented in the eighth and ninth decades of life (70, 78, 87 and 89 years). Seventy-five percent of patients had a unifocal lesion. Cases 3 or 4 presented with recurrent lesions at 5 and 10 years, respectively. All patients were treated with wide local excision. Surgical margins were free of disease. None of the patients had lymph nodes suspicious for malignancy. CONCLUSION: Basal cell carcinoma can present as a unifocal or multifocal lesion. The lesions are usually located on the labia majora. Patients are frequently diagnosed with basal cell carcinoma of the vulva in the eighth and ninth decades of life. Treatment consists of wide local excision. Although 50% of these cases recurred, the lesions were reexcised, with wide local resection. No metastatic lesions were identified in any of the patients.
Abstract: We report a case of basal cell carcinoma arising in a previously radiated field after treatment of cervical cancer. Our search of the literature yielded no other case of basal cell carcinoma due to irradiation for cervical carcinoma.
Abstract: Background: Candidal retinitis is a rare but potentially devastating infection in the postoperative patient. Due to the possibility of blindness if the diagnosis and treatment are delayed, we present this report to help educate gynecologic surgeons.Case: A postmenopausal patient presented for the treatment of ovarian carcinoma. Her surgical therapy required radical tumor debulking with partial bowel resection. The patient was begun on intravenous (IV) hyperalimentation through a central venous catheter. On the 7th postoperative day, a cephalosporin antibiotic was administered. Because of persistent fever, a septic workup was instituted and revealed an infected central venous catheter that was culture positive for Candida albicans. The patient complained of visual disturbances and an ophthalmological examination revealed candidal retinitis. Amphotericin B and fluconazole were administered with resolution of her fever and visual changes.Conclusion: The risk factors of malignancy, abdominopelvic surgery, antibiotic therapy, and IV catheters are discussed. In view of the common association of these iatrogenic factors in gynecologic and obstetrical practice, we present this case to help make physicians aware of this potentially devastating infection.
Abstract: A squamous cell carcinoma of the cervix metastatic to the skin at the site of a previous retroperitoneal drain is detailed. A review of the literature concerning skin metastases in cervical cancer is also presented. This is the only case the authors can find in the literature of squamous carcinoma of cervix metastasizing to a drain site.
Abstract: To determine if human papillomavirus (HPV) in the primary tumor was associated with disease-free survival of stage Ib cervical cancer patients, archival tissues from 47 patients were analyzed for HPV DNA by in situ hybridization (ISH) and polymerase chain reaction. HPV integration was determined by ISH signal pattern. Laboratory data were correlated with clinical parameters and disease-free survival. Kaplan-Meier estimates of 4-year disease-free survival were 56% in women with HPV detected in the primary tumor by ISH and 100% for women in whom HPV was not detected (P = .02). Four-year disease-free survival was 39% for patients with integrated HPV in the primary tumor (P = .005 vs. HPV-negative tumors and .05 vs. HPV episomal or episomal/integrated). HPV detection and integration state was not associated with any other clinical variable. Detection of integrated HPV DNA in the primary tumor was strongly associated with treatment failure.
Abstract: A case of metastatic adenocarcinoma of the endometrium following endometrial ablation is described. A discussion of the development and evolution of endometrial ablation procedures is presented. Recommendations for patient selection and postablation surveillance are suggested. The authors believe this case report to be the third described in the literature. (Background. A case of endometrial adenocarcinoma developing after transcervical endometrial ablation with a resectoscope was recently reported (A. B. Copperman, A. H. DeCherney, and D. L. Olive, Obstet. Gynecol. 82, 640-642 (1993)). It is recognized that functional residual islands of endometrial tissue remain in both symptomatic and asymptomatic patients following ablation. There is only limited experience using endometrial ablation in postmenopausal patients and in others at high risk for endometrial cancer. Case. A patient presented who developed metastatic adenocarcinoma of the endometrium after endometrial ablation for postmenopausal bleeding. Conclusion. With endometrial ablation procedures, the potential exists for missed areas or buried nests of functional endometrial tissue that may later undergo malignant transformation or have already become metaplastic and invaded the myometrium. Therefore, close postoperative surveillance, including thorough evaluation of postoperative bleeding, is indicated. Further studies with long-term follow-up are needed in order to define the safety and efficacy of endometrial ablation in the high-risk patient.
Abstract: BACKGROUND. Cervical cancer remains an important public health problem, particularly for the urban minority population. To the authors' knowledge, determinants of cervical cancer survival have not been studied in this high risk population. METHODS. This study included all 158 women diagnosed and treated for invasive cervical cancer from January 1, 1986, through December 31, 1992, at the Grady Memorial Hospital and Clinics (Atlanta, GA). Medical records were abstracted to determine age at diagnosis, race, International Federation of Gynecology and Obstetrics (FIGO) clinical stage, treatment, and survival. Pathologic material was reviewed to confirm the diagnosis. RESULTS. Most patients (80%) were African American, and the stage distribution was similar for African American and white patients. Sixty-six (42%) had FIGO Stage I disease; 50%, Stage II or III; and 8%, Stage IV. Four-year actuarial survival differed significantly according to clinical stage (Ia = 94%, Ib = 79%, II = 39%, III = 26%, IV = 0%). Overall survival was lower for patients with glandular carcinomas than for those with squamous cell carcinomas (26% vs. 55%, P = 0.09). This difference was almost entirely due to increased mortality in patients with Stage Ib adenocarcinomas (53% vs. 88% for squamous cell carcinoma, Stage Ib, P = 0.03). CONCLUSIONS. The major prognostic markers for cervical cancer survival in this high risk patient population were clinical stage and histology, factors identical to those identified for other populations.
Abstract: Sex cord stromal tumors of the ovary can be characterized by the production of virilizing steroid hormones. The authors present a case of a poorly differentiated Sertoli-Leydig cell tumor in which ascitic fluid was found to have a high concentration of androgenic hormones and precursors from the delta steroid pathway (17-OH progesterone, testosterone, and androstenedione). These values correlated with samples taken from the right ovarian vein, draining the ovarian neoplasm, but not with those taken from the left ovarian vein or the peripheral blood sample. Selective peritoneal fluid sampling may aid in the diagnosis of hormonally active tumors.
Abstract: Eight patients with benign obstetric and gynecologic conditions required embolization. There was a total of 11 embolizations, and embolizing agents were chosen depending on the abnormality requiring embolization. Gelfoam, Ivalon and alcohol were used to treat vascular malformations. Ovarian veins were embolized with coils. Postoperative bleeding was managed with Gelfoam, coils and/or Ivalon. Four patients had bleeding after hysterectomy or vaginal suspension. One patient had postdelivery bleeding. All the bleeding was controlled after embolization. A uterine arteriovenous malformation was managed with embolization, allowing the patient to carry her next pregnancy to term. The symptoms of a vulvar hemangioma and ovarian syndrome were controlled with vascular embolization. Morbidity was minimal. Embolization is the primary treatment of choice in obstetric and gynecologic patients with postoperative bleeding or symptomatic vascular malformation.
Abstract: The patient presented had primary tumors of the ovary and colon in association with pseudomyxoma peritonei. Since pseudomyxoma peritonei has been associated with mucin-producing tumor of the genital and gastrointestinal tract, a thorough evaluation of the gastrointestinal tract should be performed in patients thought to have pseudomyxoma peritonei secondary to an ovarian neoplasm.
Abstract: Medical students throughout the world learn clinical skills in a physical diagnosis course. Clinicians can use this approach to design a focus review to serve as a method of evaluation in the quality assurance of healthcare and as a research tool.
Abstract: Three hundred thirty-three patients who presented with cervical carcinoma from November 1980 through June 1985 were compared for potential factors associated with histology. Sixteen percent of all patients presenting with cervical carcinoma during this 5-year period had an adenocarcinomatous histology. Emphasis was placed on demographic and socioeconomic factors. The histologic distribution was the following: epidermoid carcinoma 279, adenocarcinoma 28, and adenoepidermoid carcinoma 26. The latter two histologies were not different for any factors and therefore combined for statistical comparison with epidermoid carcinoma. When epidermoid (E) carcinoma of the cervix was compared with the histologies having an adenocarcinomatous component (A), the following demographic and socioeconomic factors were statistically, different (P less than 0.05): Unemployment (E 69% vs. A 46%) P less than 0.002; Income less than $6000/yr (E 48% vs. A 26%) P less than 0.005; Less than a 12th-grade education (E 85% vs. A 72%) P less than 0.05; Smokers (E 67% vs. A 40%) P less than 0.001; First coital experience less than 18 years (E 58% vs. A 39%) P less than 0.05. Age, parity, and number of sexual partners were not significantly different between the epidermoid and adenocarcinoma groups. The number of patients with stages II, III, and IV was too small to provide a meaningful statistical comparison of survival for the two histologies. Our data suggest that epidermoid and adenocarcinoma of the cervix may represent diseases with distinct populations at risk.
Abstract: The effects on intestinal transport of either a semipurified preparation of enterotoxin elaborated by Klebsiella pneumoniae or similaryly prepared control material were tested by marker perfusion studies in the small intestine of rats. At a concentration of 2 mg/ml, the enterotoxin produced net secretion of water, Na, and Cl in both jejunal and ileal segments; HCO3 transport was not affected. Net secretion was evident within 30 min after intorduction of the toxin and was maximal after 90 min. The addition of 56 mM glucose to the enterotoxin-containing perfusion fluid resulted in reversal of water and Na transport to net absorption in both intestinal segments. The enterotoxin also produced a significant depression of xylose absorption in both the jejunum and ileum but did not affect the absorption of either glucose or L-leucine. Intestinal structure was not altered after perfusion of the toxin but insillation of approximately one-quarter of the total perfusion dose into a ligated jejunal loop for 18 h produced fluid secretion and structural abnormalities. These observations confirm the fact that other species of coliform bacteria in addition to tescherichia coli are capable of elaborating an enterotoxin. Such species commonly contaminate the small intestine of persons with tropical sprue and it is suggested that chronic exposure of the intestinal mucosa to the enterotoxin elaborated by these bacteria may be a factor in the pathogenesis of intestinal abnormalities in thid disorder.
