Abstract: GOALS OF WORK: Bone metastases are a common cause of morbidity in elderly patients with solid tumors and myeloma. We studied the safety and the effect of a new bisphosphonate, zoledronic acid (ZA), on pain and on quality of life (QoL) in elderly patients with bone metastases. MATERIALS AND METHODS: From January 2004 to December 2005, we have enrolled elderly patients with bone metastasis for receiving ZA administration. Visual analog scale (VAS) and Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire were used to assess potential benefits of ZA therapy. RESULTS: Eighty-six patients were included; the median age was 75.5 years. Before starting treatment, the mean VAS was 6.8 (+/-0.24), after three infusions 5.4 (+/-0.3), and after six courses 4.5 (+/-0.3) with a significant improvement of bone pain. Moreover, we found a statistically significant improvement of QoL measured by FACT-G questionnaire after six courses (p = 0.010). Median baseline and final value of serum creatinine were 0.73 and 0.72 mg/dl, respectively (p = 0.11); creatinine clearance was also normal for most patients. Osteonecrosis of the jaw was diagnosed in one patient who received a prolonged ZA treatment. CONCLUSIONS: These data confirm the benefits of ZA on pain and QoL also in elderly patients with bone metastasis from solid tumors.
Abstract: Local therapies such as radiofrequency ablation (RFA) represent a valuable choice in limited hepatocellular carcinoma (HCC) and are increasingly used also in advanced tumors. Medical treatments generally gave frustrating results in advanced HCC especially if comorbidities exist. Several biologic non-chemotherapeutic drugs are currently tested in HCC and, among them, octreotide was evaluated in single series of HCC patients reporting conflicting results. We have treated a series of 35 patients affected by advanced HCC (26 M and 9 F; age range: 55-85 years, median: 73 years) with RFA followed by octreotide to primarily evaluate the safety of combined treatment and to give preliminary evaluation on its activity. We have also evaluated serum VEGF changes during the study. Child A and Child B represented 60% and about 34% of the cases, respectively. Only two patients with Child C compensated cirrhosis were included in this study. All patients have multiple liver HCC nodules and one had bone metastases. Two complete responses, 3 partial responses and 23 disease stabilization for at least three months were obtained (overall response rate, 14,2%; clinical benefit, 80%). Mean overall survival was 31.4 months. The combined treatment was well tolerated. Statistically significant correlation was found between serum VEGF and tumor progression. In conclusion, the combination of RFA and octreotide was active in advanced HCC, however, confirmation in a larger series is required.
Abstract: PURPOSE: No standard chemotherapy has been so far definitely settled for elderly patients with metastatic breast cancer (MBC). In order to identify a regimen with acceptable efficacy and low burden of non-overlapping toxic effects, a combination consisting of liposomal pegilated doxorubicin (PLD) with alternating oral and intravenous vinorelbine (NVB) has been investigated in a phase II study. METHODS: Thirty-four consecutive patients (median age 71 years; range 65-82) with MBC have been enrolled. Based on 4-weekly cycles, PLD 40 mg/m(2) plus NVB 25 mg/m(2) i.v., have been administered intravenously on day 1 and oral NVB 60 mg/m(2) on day 15. RESULTS: All patients were assessable for safety and efficacy. In all, 17 responses were documented with three complete responses (CR) and 14 partial responses, with an overall response rate of 50% (95% CI 36-66). Median overall survival time was 13 months and the median time to progression 8 months. Interestingly, all the patients with CR are still alive with a disease-free survival of more than 1 year. The main toxicity was neutropenia: grade 3 in 15% and grade 4 in 11% of patients, respectively. Febrile neutropenia was recorded in three patients not requiring dose reduction. Other frequently reported adverse events included: anemia, nausea, vomiting, stomatitis, all rarely severe. The evaluation of quality of life (QoL) did not show any significant change during the study. CONCLUSIONS: Our data suggest that this combination is active and well tolerated in elderly patients with MBC and could represent another efficacious chance for the management of this population.
Abstract: BACKGROUND: Temozolomide (TMZ), an oral methylating imidazotetrazinone, has antitumor activity against gliomas, malignant melanomas, and brain metastasis and is presently administered as a 5-day oral schedule every 4 weeks. METHODS: A single-institution phase 2 clinical trial was conducted to determine the efficacy and the safety profile of a new regimen based on a dose-intensified, protracted course of TMZ after whole-brain radiotherapy (WBRT). Patients were eligible if they had at least 1 bidimensionally measurable brain metastasis from breast cancer and nonsmall cell lung cancer (NSCLC). Twenty-seven patients were treated with 30 grays (Gy) of WBRT with concomitant TMZ (75 mg/m(2)/day) for 10 days, and subsequent TMZ at a dose of 75 mg/m(2) per day for 21 days every 4 weeks, for up to 12 cycles. RESULTS: Two complete responses (7.4%) and 11 partial responses (40.7%) were achieved. The schedule appeared to be well tolerated, with grade 3 toxicity (graded according to National Cancer Institute Common Toxicity Criteria) observed in only 2 patients. The overall median survival was 8.8 months and the median progression-free survival was 6 months. CONCLUSIONS: The concomitant use of WBRT and protracted low-dose TMZ appears to be an active, well-tolerated regimen. The observed antitumor activity suggests the need for further investigation of this schedule in combination with other anticancer agents for the concomitant treatment of brain metastases and primary cancers.
Abstract: BACKGROUND: Brain metastases (BM) represent one of the most frequent complications related to cancer, and their treatment continues to evolve. We have evaluated the activity, toxicity and the impact on Quality of Life (QoL) of a concomitant treatment with whole brain radiotherapy (WBRT) and Temozolomide (TMZ) in patients with brain metastases from solid tumors in a prospective Simon two stage study. METHODS: Fifty-nine patients were enrolled and received 30 Gy WBRT with concomitant TMZ (75 mg/m2/day) for ten days, and subsequently TMZ (150 mg/m2/day) for up to six cycles. The primary end points were clinical symptoms and radiologic response. RESULTS: Five patients had a complete response, 21 patients had a partial response, while 18 patients had stable disease. The overall response rate (45%) exceeded the target activity per study design. The median time to progression was 9 months. Median overall survival was 13 months. The most frequent toxicities included grade 3 neutropenia (15%) and anemia (13%), and only one patient developed a grade 4 thrombocytopenia. Age, Karnofsky performance status, presence of extracranial metastases and the recursive partitioning analysis (RPA) were found to be predictive factors for response in patients. Overall survival (OS) and progression-free survival (PFS) were dependent on age and on the RPA class. CONCLUSION: We conclude that this treatment is well tolerated, with an encouraging objective response rate, and a significant improvement in quality of life (p < 0.0001) demonstrated by FACT-G analysis. All patients answered the questionnaires and described themselves as 'independent' and able to act on their own initiatives. Our study found a high level of satisfaction for QoL, this provides useful information to share with patients in discussions regarding chemotherapy treatment of these lesions.
Abstract: Primary childhood germ cell tumors (GCTs) represent a rare and heterogeneous group of tumors that varies in histologic differentiation, age of presentation and clinical outcome. In malignant neoplasms, apoptosis is a prognostic marker and a predictive factor of response to therapy. Therefore, the study of the expression and mutation of molecules involved in the regulation of apoptosis could be useful in order to both predict the clinical outcome and design self-tailored therapeutic approaches. We retrospectively analysed tissue samples of 54 childhood GCTs. The expression of p53 and BAX protein was assessed by immunohistochemistry (IHC). Moreover, we investigated the presence of mutations in the BAX and p53 genes SSCP-PCR and direct sequencing. IHC analysis of BAX protein expression showed that 14 out of 54 tumors (26%) had no BAX protein expression, in the remaining 40 patients (74%) the intensity of BAX was low in 20 patients (37%) and high/intermediate in 20 (37%). BAX was mutated in 6 patients. p53 was expressed in 43 patients (79.6%), was not detectable in the remaining 11 (20.4%) and mutated in only 3 patients. p53 mutational status and expression were not correlated to the overall survival (OS). On the other hand, both IHC score and mutations for BAX were correlated to sacrococcygeal primary localization. BAX mutations were inversely correlated with OS (p=0.0419) while BAX IHC intensity was directly correlated with OS (p=0.0376). The stratification for histotype showed a direct correlation between BAX IHC and OS in both immature teratoma (p=0.045) and mixed malignant GCT (p=0.010) while the correlation was lost in mature teratoma (p=0.300). These results indicate that both mutations and BAX protein levels are useful molecular biological markers for prognosis and clinical management of pediatric GCT.
Abstract: Here we report the concomitant development in an 82 year-old patient of three different neoplasms with different histology, degree of differentiation and clinical aggressiveness. In fact, the patient presented a verrucous carcinoma with unusual location at her head frontal region and a concomitant calcified meningioma of the frontal region of the brain. At the moment of the examination also a clear renal cell carcinoma, that was the cause of patient decease, was discovered. At our knowledge, this is the first case of concomitant presentation of these three tumours. Even if the present case was not correlated with any hereditary feature the presence of a genetic predisposition common to all the three tumours can not be excluded, but the casual co-existence of different both genetic and environmental factors can be also suggested.
Abstract: Some conditions are predisposed to excessive lymphocyte responses, which can progress to a benign condition, ie, atypical cutaneous lymphoid hyperplasia (ACLH), or a malignant lymphoma. Clinical diagnosis of drug-associated pseudolymphoma can be based on a temporal association between drug ingestion and lesion onset followed by resolution without recurrence after discontinuation of drug administration. Herein, we report the case of a 66-year-old man with advanced colon carcinoma with ACLH developed while receiving chemotherapy regimen with oxaliplatin/5-fluorouracil/leucovorin. The authors postulate that chemotherapy can promote an aberrant immune response to an antigen that can be the drug itself or other self-antigens.
Abstract: OBJECTIVE: A combination regimen of temozolomide (TMZ) and pegylated liposomal doxorubicin has been evaluated in the treatment of brain metastases from solid tumours. STUDY DESIGN: Nineteen consecutive patients (pts) have been enrolled in a prospective phase II trial and treated with TMZ 200 mg/m2 (days 1-5) and pegylated liposomal doxorubicin 35 mg/m2 (day 1) every 28 days. The study was prospectively projected according to the Simon's two-stage optimal design. RESULTS: Major toxicities have been grade III neutropenia and thrombocytopenia in one patient (pt) and grade III erythrodisesthesia in two pts. Three pts achieved a complete response (CR) and four a partial response (PR), for an overall response rate of 36.8% (95% CI: 19.1-59.2), which exceeded the target activity in the study design. A significant improvement in quality of life was demonstrated by FACT-G analysis. The median Progression Free Survival (PFS) was 5.5 (95% CI: 2.7-8.2) months while the median Overall Survival (OS) was 10.0 months (95% CI: 6.3-13.7). CONCLUSIONS: The TMZ/pegylated liposomal doxorubicin regimen was well tolerated with an encouraging activity in brain metastases from solid tumours.
