Abstract: Eosinophilic infiltrate of liver tissue is described in primary cholestatic diseases, hepatic allograft rejection and drug-induced liver injury, but its significance and its implications in chronic hepatitis C are unknown. The aim of this study was to investigate the clinical significance of eosinophilic liver infiltrate in patients with chronic hepatitis C. We retrospectively evaluated 147 patients with chronic hepatitis C. The presence of eosinophilic infiltrate was investigated in liver biopsies, and a numeric count of eosinophilic leucocytes in every portal tract was assessed. An eosinophilic infiltrate of liver tissue (>/=3 cells evaluated in the portal / periportal spaces) was observed in 46 patients (31%), and patients who consumed drugs had an odds ratio (OR) of 4.02 (95% CI: 1.62-9.96) to have an eosinophilic infiltrate in liver biopsy. By logistic regression analysis, the presence of steatosis was independently associated with eosinophilic infiltrate (OR 5.86; 95% CI: 2.46-13.96) and homeostasis model assessment-score (OR 1.18; 95% CI: 1.00-1.39). Logistic regression analysis also showed that fibrosis staging >/= 2 by Scheuer score was associated with grading >1 by Scheuer score (OR 6.82; 95% CI 2.46-18.80) and eosinophilic infiltrate (OR 4.00; 95% CI 1.23-12.91). In conclusion, we observed that the eosinophilic infiltrate of liver tissue was significantly more frequent in patients who assumed drugs, and found a significant association between eosinophilic infiltrate, liver steatosis and liver fibrosis. These preliminary data could lead to a constant assumption of drugs as a co-factor of eosinophils-mediated liver injury in chronic hepatitis C.

Abstract: BACKGROUND: BRAF(V600E) mutation and p27(kip1) expression have been introduced as novel indicators that may predict prognosis in different tumors, as well as in papillary thyroid carcinomas. METHODS: Tissue samples from 214 consecutive patients who underwent total or near-total thyroidectomy with histological diagnosis of papillary thyroid carcinoma (PTC) <or=1 cm were analyzed for BRAF(V600E) mutation by a real-time, allele-specific amplification and for p27(kip1) expression by immunohistochemistry. RESULTS: The BRAF(V600E) mutation was detected in 88 of the tumors examined, with significant differences between groups with and without lymph node (LN) metastases; the mean age of patients with BRAF(V600E) mutation was significantly higher than that of patients without mutations. A significant association was found between low p27(Kip1) protein expression and multifocality, bilaterality, and extrathyroidal extension, in addition to LN metastasis. In 42 cases with LN metastases, 23 harbored the BRAF(V600E) mutation in the metastatic tumor and presented a wider diameter of the largest metastatic area, a higher number of involved LNs, and a higher percentage of metastatic lesions with extracapsular extension of LN (ECE-LN). A significantly lower mean value of p27(Kip1) was observed in LNs harboring the BRAF(V600E) mutation and in ECE-LN; an inverse correlation was found between p27(Kip1) and the number of metastatic LNs, as well as the diameter of the largest metastatic area in LN. CONCLUSIONS: The authors' data suggested that BRAF(V600E) mutation and p27(Kip1) down-regulation in cancer cells of PTC <or=1 cm may be factors that facilitate tumor-cell growth and progression once these are seeded in the LNs.

Abstract: We present a case of late granulomatous reactions from silicone that first appeared in a site different from that of the injection causing an incorrect diagnosis of liposarcoma in the beginning. The histological picture was a cystic-macrophagic granuloma in both the injection site (upper lip) and the migrating site (paranasal regions). We think that the foreign body has undergone an antigravity migration from the upper lip to the right paranasal region. To our knowledge, such a phenomenon has not been yet reported in literature.

Abstract: BACKGROUND: To date an accurate evaluation of predictive markers in breast cancer is mainly conducted at the primary site, although the main goal of the adjuvant therapy is the control of micrometastases. Adjuvant therapy drugs need a high proliferative cell rate to be effective. The proliferating activity can be evaluated by the Ki-67 marker and even by thymidylate synthase (TS), a cell cycle enzyme present in proliferating cells. In this study the TS levels in primary tumours were compared to those of their metastases. PATIENTS AND METHODS: The TS expression and Ki-67 were evaluated by means of immunohistochemistry in 80 primary breast tumours (PTs) and in their matched axillary metastatic lymph-nodes (ALNs). RESULTS: In 16% of patients, malignant cells of involved nodes showed a lower TS expression than the PTs. In the same group, we also found a lower number of Ki-67 immunoreactive cells in lymph node metastases when compared with primary tumours. CONCLUSION: The group of patients with lower TS and Ki-67 expression in lymph node metastatic cells may be less sensitive to 5-fluorouracil and high dose methotrexate requiring them to be treated with other drug combinations.

Abstract: OBJECTIVE: To verify whether immunohistochemistry might be useful in the distinction between a true laterocervical metastasis of an undetected thyroid carcinoma and a primary tumor outside the gland. DESIGN: Galectin-3, cytokeratin 19, and HBME-1 were assessed in six cases (group A) of laterocervical masses harboring papillary thyroid carcinoma (PTC) but without a thyroid tumor, and in eight cases (group B) showing PTC both in the thyroid and in the laterocervical masses. In both groups, normal-looking follicles adjacent to the laterocervical neoplasia were present. MAIN OUTCOME: We found that the apparently normal follicles in group A were negative for all the antibodies, while group B showed strong and diffuse positive immunostaining. The neoplastic areas were always positive for all the antibodies in both groups. CONCLUSION: Even if immunohistochemical patterns of residual follicles of group B are very well differentiated that they resemble normal thyroid parenchyma, they may well be metastatic carcinomas. On the contrary, the presence of morphologically and immunohistochemically normal-looking follicles in group A, with no intrathyroid tumor, suggests that the primary PTC might possibly develop in the ectopic thyroid tissue. In cases showing morphologically and immunohistochemically normal-looking follicles in laterocervical masses, these findings might lead to a reduction of the overdiagnosis of metastatic disease of an undetected carcinoma.

Abstract: OBJECTIVE: We aimed to investigate the existence of associations between well-established and newly recognized biological and phenotypic features of breast cancer involved in tumor progression and prognosis. METHODS: Ninety-eight cases of invasive breast cancer were assessed for the immunohistochemical expression of estrogen and progesterone receptors, Ki-67, HER2, Akt-1, and Notch-2, using the tissue microarray technique. Data regarding tumor histotype, histological grade, tumor size and lymph node status were collected for each patient and included in the analysis. RESULTS: Several significant associations between histological and/or immunophenotypic features came from the analysis of our data. Positive associations were observed between estrogen and progesterone receptors, tumor grade and proliferation index, tumor grade and HER2, Akt-1 and estrogen receptors, and Notch-2 and HER2. Inverse associations were noted between hormone receptors and tumor grade, hormone receptors and HER2, Akt-1 and tumor grade, and Akt-1 and nodal invasion. CONCLUSIONS: Our results, showing the existence of a number of estrogen receptor-positive tumors with Akt-1 expression, better degree of differentiation, and no lymph node involvement, along with the presence of HER2-positive tumors with strong Notch-2 expression, support the role of Notch and Akt in breast cancer progression and suggest that they may also represent new appealing therapeutic targets.

Abstract: BACKGROUND: The development of oesophageal adenocarcinoma is generally closely associated with the presence of a specialised intestinal-type epithelium such as that found in Barrett's oesophagus (BO). A particular histological condition is when the distal oesophagus showing cardiac and/or fundic mucosa without intestinal metaplasia cannot be defined as 'Barrett's mucosa' [condition that we call 'columnar-lined oesophagus' (CLO)] and up till now, there has been no agreement in literature about the management of this condition. Aurora-A overexpression leads to centrosome amplification, chromosomal instability and aneuploidy in mammalian cells. PATIENTS AND METHODS: A prospective study was carried out on 28 consecutive patients who presented columnar mucosa above the gastro-oesophageal junction (GOJ) at endoscopy. As controls, two more biopsies were obtained, one on the normal-appearing squamous oesophagus above the GOJ, as far as possible from the columnar mucosa (controls A), and one taken 1 cm below the GOJ (controls B). The Aurora-A and p53 expression levels were analysed respectively by Quantitative Real Time PCR and immunohistochemistry. RESULTS: Twelve patients were affected by BO (43%) while the other 16 patients (57%) had a CLO. Nine of 28 (32%) cases were focally positive for p53 immunostaining. All the BO/CLO samples were positive for the Aurora-A transcript with regard to controls. Furthermore, 13 of 28 (46%) cases showed overexpression (above the median for the whole group). CONCLUSION: Due to the low number of cases, we are not at present able to state that statistically significant quantitative differences in Aurora-A messenger RNA expression exist between CLO and BO cases with and without dysplasia and p53-positive immunostaining. Further studies on a larger number of cases with a follow-up period are necessary in order to establish the risk of progression and the correct management of these subjects.

Abstract: PURPOSE: The aim of this study was to evaluate the role of digital cineradiography associated with the water siphon test (WST) in the diagnosis of gastroesophageal reflux and to compare the results with oesophageal motility study, pH monitoring and endoscopy associated with biopsy and histology. MATERIALS AND METHODS: One hundred and sixty consecutive patients underwent digital cineradiography with WST, motility study, pH monitoring and endoscopy with biopsy. The presence of gastroesophageal reflux, oesophagitis, Barrett's oesophagus and intestinal metaplasia was evaluated. RESULTS: WST vs. pH monitoring showed sensitivity of 71%, specificity of 31%, positive predictive value (PPV) of 53% and negative predictive value (NPV) of 50%; when middle-proximal refluxes only were considered, sensitivity decreased to 45% and specificity increased to 55%. Furthermore, the association between reflux and oesophagitis demonstrated by the chi-square (chi(2)) test proved to be statistically significant both for WST and pH monitoring, whereas the association between reflux and Barrett's oesophagus was not significant for either WST or for pH monitoring. With regard to intestinal metaplasia, WST (middle-proximal refluxes) showed higher sensitivity (64% vs. 58%) and specificity (63% vs. 51%) than pH monitoring, whereas the statistical association between reflux and metaplasia proved to be significant for WST but not for pH monitoring. CONCLUSIONS: WST is a simple, inexpensive and reliable test that might be useful in the diagnosis of gastroesophageal reflux disease (GERD). A positive WST might be an additional indication for endoscopy with biopsy.

Abstract: OBJECTIVE: To evaluate BRAF(V600E) mutation on consecutive fine-needle aspiration biopsy (FNAB) specimens in order to assess FNAB's usefulness in preoperative papillary thyroid carcinoma (PTC) diagnosis with the contemporaneous analysis of RET/PTC1 and RET/PTC3 rearrangements obtained from ex vivo thyroid nodules. DESIGN: Thyroid FNABs from 156 subjects with nodules and 49 corresponding surgical samples were examined for the presence of BRAF mutation by real-time allele-specific polymerase chain reaction, confirmed with the use of a laser pressure catapulting system. Samples were also examined for RET/PTC rearrangements. The results were compared with the cytological diagnosis and histopathology. MAIN OUTCOMES: 13/156 cytological examinations were diagnostic for PTC and 19/156 showed suspicious/indeterminate FNAB (12.2%). FNAB-BRAF(V600E) mutation was detected in 11/16 (69%) cases with histological confirmation of PTC. In our series, RET/PTC rearrangement was detected in only one case of PTC, whereas it was not present in any case of adenoma, goiter, or Hashimoto's thyroiditis. No PTC case was found positive at the same time for BRAF mutation and RET/PTC rearrangements. CONCLUSION: BRAF(V600E) mutation detected on FNAB specimens, more than RET/PTC rearrangements, is highly specific for PTC and its routine research might well be an adjunctive and integrative diagnostic tool for the preoperative diagnostic iter.

Abstract: BACKGROUND: Lichen planus (LP) is a mucocutaneous inflammatory dermatosis that frequently involves the oral and genital mucosae. Patients with LP affecting these sites are often seen by oral medicine specialists or gynaecologists who work in isolation and depend heavily on histopathologists to help them in confirming the diagnosis. There are few studies in the literature combining the experiences of these specialists who share the care of patients with both oral and genital LP. OBJECTIVES: To estimate the prevalence of vulval LP (VLP) in a cohort of patients with histologically confirmed oral LP (OLP). METHODS: The study group consisted of 42 women histologically diagnosed with OLP. The mean age was 60.5 years (range 27-81). They underwent genital examination, colposcopy and vulvoscopy. For the histological confirmation of clinical VLP biopsies were performed whenever a clinical lesion was found. Oral and genital biopsy specimens were processed through histological and immunohistochemical staining. Histological diagnoses of LP were made according to the modified World Health Organization histopathological criteria proposed by van der Meij and van der Waal for the diagnosis of OLP, and extended to VLP. Patients with clinical evidence, but without the histological confirmation of OLP and VLP, were excluded from the study group. RESULTS: Thirty-two vulval and one vaginal biopsy specimens were obtained. Histological diagnoses were confirmed in 24 of 32 (75%) patients who underwent a vulval biopsy: these represent 57% (24 of 42) of the study group. Of the 12 patients free of symptoms such as itching, burning and dyspareunia, but with clinical vulval lesions, 11 (92%) had histological confirmation of VLP. Vulval lichen sclerosus was ascertained in five of 32 (16%) cases. CONCLUSIONS: This study showed a 57% prevalence of VLP in selected patients with OLP. The high prevalence of VLP of 92% in the women who were free of vulval symptoms confirmed the usefulness of this careful integrated approach.

Abstract: BACKGROUND: Transformation of a cystic benign teratoma of the ovary into a "carcinosarcoma" has very rarely been reported and its histogenetic origin is still debated. CASE PRESENTATION: A case of carcinosarcoma arising from a dermoid cyst is reported. The tumor showed cystic areas delimited by normal squamous epithelium, with transitional areas through dysplastic epithelium to "in situ" and infiltrating squamous cell carcinoma (SCC). The sarcomatous component showed compact tissue composed of round cells concentrically arranged around small vessels, spindle, and pleomorphic cells with a high nuclear-cytoplasmic ratio. Positive staining for vimentin, alpha smooth muscle actin and CD10, as well as P53 and P63, was found in the sarcomatous component and in some atypical basal cells of the squamous epithelium, which also showed the usual epithelial markers. CONCLUSION: To the best of our knowledge, this is the first case of carcinosarcoma arising from a dermoid cyst in which a histogenetic origin from totipotent stem cells, located in the basal squamous layer, is supported by immunohistochemical findings.

Abstract: Sarcoidosis is a systemic disorder characterized by granulomatous lesions, principally affecting the lungs. There are numerous reports in the literature of an associated involvement of the thyroid, much more frequently in hypothyroid than in hyperthyroid subjects. The present case report refers to a woman presenting with thyroid nodules and normal biochemical levels and thyroid function parameters, while histology revealed sarcoid-type lesions. Subsequent investigations and a long follow-up showed no evidence of involvement of other sites, including the lungs. Consequently, after a long period of normal health associated with the negative results of the examinations, a diagnosis of sarcoidosis limited to the thyroid was proposed, which was cured by thyroidectomy.

Abstract: The main aims of this cross-sectional study were: (i) to assess the frequency of genital (vulval) lichen planus (VLP) and vulval lichen sclerosus (VLS) in women affected with oral lichen planus (OLP), regardless of the genital symptoms reported; and (ii) to verify whether any demographic, clinical, or histological features of OLP are associated with a higher risk of vulvo-vaginal involvement. Fifty-five women, presenting OLP, consecutively underwent gynaecological examination and, if they demonstrated positive clinical signs of VLP, underwent biopsy. After a drop-out of 14 subjects, 31/41 (75.6%) were found to have signs of genital involvement, of which 13/31 (44.0%) were asymptomatic. Following genital biopsy, 27/31 (87.1%) had histologically confirmed VLP or VLS. Following both univariate and multivariate statistical analyses, no significant association was found between gynaecological concomitance and demographic, clinical, histological features of OLP. This unpredictably common genital involvement in females with OLP emphasizes the importance of routinely performing both oral and gynaecological examinations, to facilitate an early and correct therapeutic approach.

Abstract: Breast cancer is a heterogeneous disease, so therapeutic predictive biological markers need to be identified. To date an accurate evaluation of predictive markers is mainly done at the primary site; however, the main goal of adjuvant therapy for breast cancer is the control of micrometastases. The aim of this study is to assess as therapeutic and/or prognostic marker, the proliferation status of primary tumors and involved nodes as measured by Ki67 and thymidylate synthase (TS) expression, in 30 breast cancer node positive patients. TS is the main target of 5-fluorouracil (5-FU) activity, and its overexpression is one of the mechanisms of 5-FU drug resistance; however, in some studies its absence is responsible for a worse response to 5-FU. Our results show that malignant cells of involved nodes were in a post mitotic phase of the cell cycle, and show a low proliferation index and TS expression, while the primary tumours and controls, were strongly positive. On these basis we can hypothesize that these cells could be less sensitive to 5-FU. Further studies are necessary to identify other mechanisms responsible for their metastasing capability and/or for their aggressiveness.

Abstract: The aim of the study was to verify by Ki-67 immunostaining if any difference exists in the cell proliferating fraction between primary breast tumors (PTs) and matching positive axillary lymph nodes (ALNs). PATIENTS AND METHODS: Immunohistochemistry with the monoclonal antibody against Ki-67 was performed in 160 node-positive breast carcinomas and in their respective lymph node metastases. RESULTS: An increase of Ki-67 immunoreactive cells in ALN compared with that of PTs was observed in 84% of cases (ALN: mean 17%, PTs: mean 8%; p < 0.001), whereas 16% of the cases showed Ki-67 value two to six times lower in the ALNs than in the corresponding PTs (ALN: mean 3.2%, PTs mean 12.5%; p < 0.005). The decrease of Ki-67 positive cells in the ALN was independent from the histotype and the histological grade of the tumor. CONCLUSION: A different cell proliferation fraction between PTs and matching positive ALNs was demonstrated and underlined that the existence of a group of patients with decreased number of Ki-67 immunoreactive cells in lymph node metastases compared with that of the primary tumors could be taken into account in the choice of therapeutic strategy.

Salvatore Vieni, Daniela Cabibi, Calogero Cipolla, Salvatore Fricano, Giuseppa Graceffa, Mario Adelfio Latteri (2006)  Secretory breast carcinoma with metastatic sentinel lymph node.   World J Surg Oncol 4: 12  
Abstract: BACKGROUND: Secretory mammary carcinoma is a rare breast neoplasia originally described in children but sometimes also found in adults. It presents a more favourable outcome than more common histological types of breast carcinoma; published literature in fact reports only a few cases with axillary lymph node metastases and only four cases with distant metastases. CLINICAL PRESENTATION: In this paper we report a rare case of secretory breast carcinoma with axillary lymph node metastases in a 33-year-old woman. To our knowledge, this is the first case of secretory carcinoma involving biopsy of the sentinel lymph node and investigation of the e-cadherin expression.We found positivity for e-cadherin, which would support the hypothesis that this type of tumour is a variant of the infiltrating ductal carcinoma. CONCLUSION: After a careful analysis of reported data, we have come to the conclusion that the treatment of choice for patients with secretory breast carcinoma should be conservative surgery with sentinel lymph node biopsy, followed by accurate follow-up. We are of the opinion that while post-operative radiotherapy is indicated in adult patients who have undergone quadrantectomy, it should not be used in children. Although several cases of secretory carcinoma have been treated with adjuvant chemotherapy, there are still no reliable data regarding the real value of such a choice.

Abstract: We have attempted to identify those subgroups of patients most likely to develop lymph node metastases from squamous cell carcinoma of the lower lip (LLSSC). A total of 97 subjects, who did not undergo elective neck dissection, were recruited into the 60-month disease-free survival study. After univariate analysis, tumour size, histological grading, maximal thickness, perineural invasion and immunoreactivity to cyclin D1 and p27Kip1 proteins proved to be significant factors. Tests of the effect of interaction between p27Kip1 LI and tumour thickness yielded that the impact of tumour thickness on the risk of lymph node metastases was modified by the percentage of p27Kip1 positive cells. Subsequent to models of multivariate analysis, tumour size, positive cyclin D1 protein expression, maximal thickness (> 5 mm), p27Kip1 LI (%) and the interaction term between p27Kip1 LI and tumour thickness retained strong independent predictive values for lymph node metastases. We suggest that immunohistochemistry for cyclin D1 and p27Kip1 may prove to be valuable ancillary tests for identifying LLSSC with metastatic potential.

Abstract: The aim of this preliminary study conducted in a few cases was the retrospective evaluation of the effects of laparoscopic Nissen fundoplication on oesophageal intestinal metaplasia. Seventy-seven patients with hiatal hernia underwent digital videofluorography, endoscopy with biopsies, motility studies and 24-h oesophageal pH-monitoring. On the basis of the results of the diagnostic procedures and considering the patients' ages and response to proton-pump inhibitor treatment, 8 patients underwent laparoscopic Nissen fundoplication; in 5 cases intestinal metaplasia was present at histopathological examination. Two of these had Barrett's oesophagus at endoscopy and intestinal metaplasia was associated with low-grade dysplasia in both at histology; the other 3 did not present a columnar mucosa at endoscopy and 1 had low-grade dysplasia. In all 5 patients, at 1 year postoperative histopathological control, disappearance or decrease of metaplastic epithelium and regression of dysplasia were noted, with excellent results in terms of reflux symptoms at clinical control. On the basis of these preliminary data, it is our opinion that antireflux surgery is not only a suitable treatment in the management of Barrett's oesophagus but also has a favourable effect on intestinal metaplasia regression when a normal oesophageal mucosa is present.

Abstract: Schistosomiasis is a chronic worm infection caused by a species of trematodes, the Schistosomes. We may distinguish a urinary form from Schistosomes haematobium and an intestinal-hepatosplenic form mainly from Schistosomes mansoni characterized by nausea, meteorism, abdominal pain, bloody diarrhea, rectal tenesmus, and hepatosplenomegaly. These infections represent a major health issue in Africa, Asia, and South America, but recently S mansoni has increased its prevalence in other continents, such as Europe countries and North America, due to international travelers and immigrants, with several diagnostic and prevention problems. We report a case of a 24-year-old patient without HIV infection, originated from Ghana, admitted for an afebrile dysenteric syndrome. All microbiologic studies were negative and colonoscopy revealed macroscopic lesions suggestive of a bowel inflammatory chronic disease. Since symptoms became worse, a therapy with mesalazine (2 g/d) was started, depending on the results of a bowel biopsy, but without any resolution. The therapy was stopped after 2 wk when the following result was available: a diagnosis of ""intestinal schistosomiasis" was done (two Schistosoma eggs were detected in the colonic mucosa) and this was confirmed by the detection of Schistosoma eggs in the feces. Therapy was therefore changed to praziquantel (40 mg/kg, single dose), a specific anti-parasitic agent, with complete recovery. Schistosomiasis shows some peculiar difficulties in terms of differential diagnosis from the bowel inflammatory chronic disease, as the two disorders may show similar colonoscopic patterns. Since this infection has recently increased its prevalence worldwide, it has to be considered in the differential diagnosis of our patients with gastrointestinal symptoms.

Abstract: We describe a rare case of a solid variant of a mammary adenoid cystic carcinoma with basaloid features (sbACC) and its coexistence with a "small cell" carcinoma (SCC), identified and confirmed by histological and immunohistochemical observations: the absence of glandular structures and PAS-positive globules, positivity for neuroendocrine markers (NSE, synaptophysin and chromogranin), and negativity for 34betaE12 and SMA actin were the aspects suggesting the presence of SCC. Furthermore, positivity for CD10 was found both in sbACC and in SCC, supporting the hypothesis that the two components share the same histogenetic myoepithelial origin and represent an example of dedifferentiation along neuroendocrine phenotype lines occurring in a multipotential neoplastic stem line, already committed towards a myoepithelial phenotype. To our knowledge, this is the first reported case of a solid basaloid adenoid cystic carcinoma merging with an SCC carcinoma. Furthermore, it is the first study in which CD10 was used to investigate the histogenesis of the two neoplastic components.

Abstract: The aim of the study was to evaluate the correlation between hiatal hernia and gastro-oesophageal reflux and related histological abnormalities in patients without endoscopic oesophagitis. A consecutive series of 78 patients with a history of gastro-oesophageal reflux symptoms and hiatal hernia, as defined by videofluorography combined with a water siphon test, underwent oesophagogastroduodenoscopy and multiple biopsies. Hiatal hernia was confirmed endoscopically in 99% of cases. The water siphon test was positive for reflux in 72% of cases. At endoscopy 42% of patients had oesophagitis and/or Barrett's oesophagus and 58% had no lesions. In the group without endoscopic lesions, at histology oesophagitis-related alterations were found in 98% and intestinal metaplasia in 27%. In conclusion, this study shows that symptomatic gastro-oesophageal reflux patients with radiologically defined hiatal hernia should undergo endoscopy with multiple biopsies above the squamocolumnar junction, even when endoscopy is normal. This is in order to detect histological gastro-oesophageal-reflux-related alterations, above all, when a positive water siphon test is also present, owing to its known correlation with intestinal metaplasia.

Abstract: BACKGROUND: Microsatellite instability (MSI) is a biological characteristic of most tumours, being involved in 85% of hereditary non-polyposis colorectal cancer (HNPCC). It also occurs in 10-15% of sporadic colorectal cancers (CRC). HNPCC appears to be caused by germline mutations in mismatch repair (MMR) genes, which are responsible for repairing single base-pair mismatches. MSI is also associated with a better response of CRC to adjuvant chemotherapy with fluoropyrimidines. We investigated any relationship between the MSI status and the TSmRNA expression, the polymorphisms of 5-Fluorouracil (5-FU cellular target, the enzyme thymidylate synthase (TS) and TS expression evaluated by means of immunohistochemistry. MATERIALS AND METHODS: A series of 80 colorectal cancers was evaluated for MSI and polymorphisms in the 3'UTR and the 5'UTR of the TS gene by a PCR assay. TSmRNA was quantified by real-time PCR and the TS expression by immunohistochemical assay. RESULTS: There was no significant association between the polymorphisms in the TS gene and the MSI or between the TSmRNA expression and the MSI status. CRC with a 3R/3R or 2R/3R genotype showed a significantly higher TSmRNA expression than those with the 2R/2R genotype (p = 0.001 and p = 0.028, respectively). Another significant association was found between the TSmRNA expression and the TS immunohistochemical determination (p = < 0.05). No association was found between the polymorphism of the 3'UTR and the TSmRNA expression. CONCLUSION: Our data show that there is no association between MSI status and the polymorphisms in the 3' and 5' UTRs and the TS expression. Tumour samples displaying the 3R/3R or 2R/3R genotype of TS have higher TSmRNA levels than the 2R/2R genotype. Polymorphic variant of the 3'UTR does not influence the TSmRNA level. We found a relationship between the TSmRNA expression, evaluated by real-time PCR, and with the TS level determined by immunohistochemical assay. Thus, genotyping of the 5'UTR and quantification of the TSmRNA expression in human CRC could be considered as predictors for response to SFU-based chemotherapy. The evaluation of the TS expression by means of immunohistochemistry assay remains a safe and reliable assay in CRC.

Abstract: Thymidylate Synthase (TS) is the key enzyme for DNA synthesis pathways and is inhibited by 5-fluorouracil (5FU). The aim of this work was to study TS expression and the proliferation rate in the different histological types of colorectal carcinoma (CRC). 50 patients with CRC were included in this study and evaluated immunohistochemically using the monoclonal antibodies, TS106 and Ki67. 20 tumours were of the intestinal type, 15 cases were signet ring cell carcinoma (SRCCs) and 15 cases were "mixed-type", with at least two different histological components. Intestinal and mucinous histotypes were positive for TS and Ki67, while "signet ring cell" samples were negative or showed only weak and focal positivity for both the TS and Ki67 antibodies. Our results show that signet ring cells (that are also often present in intestinal and mucinous carcinomas), are in the post-mitotic phase of the cell cycle and show a low proliferation index and TS expression. As TS is the key enzyme for DNA synthesis pathways and is inhibited by 5-fluorouracil (5FU), we can hypothesise that TS expression levels in the different histotypes of CRC could affect the potential responsiveness of these tumours to fluoropyrimidine chemotherapy, with a low efficacy being expected in signet ring cell areas.

Abstract: Expression of cytokeratin 7 (CK7) and cytokeratin 20 (CK20) helps to establish the origin of biliary and metastatic carcinomas. We investigated the expression of CK7 and CK20 in inflammatory, metaplastic and neoplastic conditions of the bile ducts, and evaluated possible relationships between the CK expression pattern and extrahepatic bile duct/gallbladder carcinomas (EBDCs) or intrahepatic bile duct carcinomas (IBDCs). We used immunohistochemistry for the investigation of 48 formalin-fixed, paraffin-embedded specimens grouped as: A) lithiasic or inflamed surgically resected extrahepatic bile ducts/gallbladders: all were CK7+/CK20+; B) percutaneous liver biopsies from patients with chronic hepatitis C primary biliary cirrhosis and primary sclerosing cholangitis: all were CK7+/CK20-; C) EBDCs: all were CK7+/CK20+, except for two cases which were CK7-/CK20-; D) IBDCs: all were CK7+/CK20-, except for one case showing CK20 positivity. Metaplastic changes were seen only among specimens in groups A and C: in these cases, CK20 was either focally or diffusely expressed. Our study suggests that the expression of cytokeratins under specific stimuli can be different from normal tissues, and that sometimes CK20 expression can be related to and precede the occurrence of metaplastic alterations.

Abstract: We selected 63 prostate tumors with Gleason's grade 6 (3+3), commonly showing both tubular and cribrous patterns. We compared in both patterns the expression of two of the most used biologic markers: PCNA and p53, with the aim to verify the validity of the Gleason's grading system to compare the morphologic grade with biologic aggressiveness and prognostic value. We did not find any statistical difference in the protein immunopositivity, indicating that both patterns could have identical biologic behaviour; then we confirmed the validity of Gleason's system for considering both tubular and cribrous patterns as an intermediate grade of tumoral differentiation. Moreover, we found a linear relationship between the increase of PCNA and the accumulation of mutated p53; this datum could confirm the hypothesis that p53 mutation is a late event in prostate carcinogenesis.

Abstract: In this study the relationship between cyto-morphometric characteristics of breast cancer and lymph node status was investigated. The study was conducted on 20 cases of T1-T2 breast cancer with node metastasis and 20 cases of T1-T2 breast cancer without node metastasis. About 100 nuclei for each patient were analyzed by means of a computerized image analyzer, and mean nuclear diameter, mean nuclear area, mean form factor and number of cells in 8 classes of diameter were studied. Mean mitotic index was also calculated. No statistic difference was found for all these variables, between the two groups. In conclusion, cyto-morphometric parameters although often represent an index of aggressiveness, they are not related to lymph node status. This one is, in fact, only an indicator of tumor's ability to spread, and tumor's diffusion can occur through different ways from the lymphatic one.

Abstract: To distinguish prostatic dysplasia (or adenosis) from well differentiated adenocarcinoma on transrectal needle biopsy, a morphometric study was conducted on 20 cases of adenosis and 20 cases of well differentiated adenocarcinoma of the prostate. About 100 cells for each patient were analyzed by means of a computerized image analyzer, and mean nuclear diameter, mean nuclear area, mean form factor and number of cells in eight classes of nuclear diameter were studied. The best predictors of malignancy (evaluated by means of Receiver Operating Characteristics curves) were mean nuclear area greater than 28 mu2, presence of more than 5% of cells with nuclear diameter greater than 6.15 mu, and mean nuclear diameter greater than 5 mu. Using these diagnostic criteria the probability of malignancy for a positive specimen rises from 14% (pre-test) to 75% (post-test).

Abstract: Experiments on the biologic effects of ultrasound (US) were carried out on rat embryos exposed for 120 s to a US beam showing features similar to those already employed for diagnostic purposes. Electron microscopic investigation of the liver parenchyma of rat embryos confirmed results obtained from adult guinea pigs with the same duration of exposure, i.e. diffuse vacuolization of cytoplasma and varying degrees of mitochondrial damage.
