Weekly docetaxel and epirubicin in treatment of advanced hormone-refractory prostate cancer.

OBJECTIVES: To evaluate the efficacy and safety of a new regimen that combines weekly docetaxel and weekly epirubicin for the treatment of advanced hormone-refractory prostate cancer. METHODS: Docetaxel 30 mg/m2 and epirubicin 30 mg/m2 were intravenously administered on a weekly basis, for a maximum of 24 cycles. The therapy was discontinued after the first 12 cycles in the patients who responded or had stable disease and was resumed as soon as any signs of progression were noted. RESULTS: Of the 38 evaluable patients, 26 achieved a confirmed greater than 50% decrease in prostate-specific antigen level (68.4%, 95% confidence interval [CI] 51.2% to 82.0%). The median response duration was 8.8 months (95% CI 6.2 to 11.8), and the median time to progression was 7.4 months (95% CI 5.6 to 9.6). Pain was rapidly reduced in 24 (72.7%, 95% CI 54.2 to 86.7) of the 33 patients who were symptomatic at baseline. Of the 38 patients, 21 resumed therapy after the planned interruption; of these, 3 had a prostate-specific antigen response (14.2%) and 12 had stable disease (57.1%). The regimen was well tolerated. Grade 3 neutropenia occurred in 15.7% of the patients, grade 3 anemia in 13.1%, and grade 3 thrombocytopenia in 7.8%. CONCLUSIONS: The results of this study have suggested the feasibility and tolerability of the combination of weekly docetaxel and weekly epirubicin, which led to a rapid and long-lasting decrease in prostate-specific antigen levels and a palliative response in patients with advanced hormone-refractory prostate cancer.

Weekly high-dose calcitriol and docetaxel in patients with metastatic hormone-refractory prostate cancer previously exposed to docetaxel.

OBJECTIVE: To evaluate the activity and tolerability of weekly high-dose calcitriol and docetaxel in patients with metastatic hormone-refractory prostate cancer (HRPC) previously exposed to docetaxel, as patients who progress after docetaxel treatment might be considered for second-line chemotherapy, but with no standard salvage therapy available we hypothesised that high-dose calcitriol might restore sensitivity to chemotherapy. PATIENTS AND METHODS: The study comprised 26 patients who had progressed after first-line treatment with docetaxel-based chemotherapy had failed. Treatment cycles consisted of calcitriol (32 microg orally as 0.5 microg tablets) on day 1 and docetaxel (30 mg/m(2) intravenous) on day 2, administered for six consecutive weeks followed by a 2-week rest interval for a maximum of 24 cycles. RESULTS: There was a response in prostate-specific antigen (PSA) level in eight patients (31%); seven (27%) had a stable PSA level for >/= 12 weeks. The median time to PSA progression was 4.2 months and the median survival was 9.3 months. The regimen was generally well tolerated; there was grade 2 hypercalcaemia, probably related to calcitriol, in one patient after six treatment cycles. CONCLUSION: Weekly high-dose calcitriol and docetaxel seems to be an effective and well-tolerated treatment option for patients with metastatic HRPC previously exposed to docetaxel-based chemotherapy.

Capecitabine as third-line treatment in patients with metastatic renal cell carcinoma after failing immunotherapy.

The aim of this study was to evaluate the activity and toxicity of capecitabine as third-line treatment in patients with advanced renal cell carcinoma for whom immunotherapy had failed. Twenty-one patients with metastatic clear renal cell carcinoma were enrolled. Capecitabine was administered orally twice daily at a dosage of 2500 mg/m(2) for 14 days, followed by 7 days of rest. The median number of administered cycles was five (1-13). One patient (4.8%) achieved a remission after eight treatment cycles. Stable disease was observed in nine patients (42.8%), whereas 11 progressed (52.4%). The estimated median time to progression was 3.6 months (confidence interval: 1.4 to 5.2). The estimated median overall survival was 7.2 months (confidence interval: 4.6 to 8.8). The regimen was well tolerated and no unexpected toxic effects were observed. Capecitabine as third-line treatment showed a favourable toxicity profile, but exhibited low activity in patients with advanced renal cell carcinoma after failing immunotherapy.

Hypospadias: incidence and effects on psychosexual development as evaluated with the Minnesota Multiphasic Personality Inventory test in a sample of 11,649 young Italian men.

PURPOSE: We evaluated the incidence of hypospadias and its effects on psychosexual development in a sample of 11,649 young Italian males. Over the last 30 years only about 30 major publications have addressed these issues and the results of many studies have been contrasting. Some defects in methodology, such as low response rates, heterogeneity of age ranges and the choice of controls, have been the main limitations. Our study was designed to take these problems into account. MATERIALS AND METHODS: Forty-two hypospadic subjects and a random sample of 500 nonaffected males selected from the large sample of 11,649 young men (>90% of the 18-year-old males living in the Italian region of Tuscany) were screened by the Minnesota Multiphasic Personality Inventory (MMPI) test, psychological interview and clinical evaluation. RESULTS: The incidence of hypospadias in this representative group of Italian men is 3.6/1,000. No difference was noted in the percentage with altered MMPI compared with the control group. The age at surgical corrections and the number of operations are not related to an abnormal global psychological adjustment. Severity of disease influences a more negative genital appraisal and the number of operations is correlated only with more difficulty in initiating contact with the opposite sex. CONCLUSIONS: Surgery for hypospadias has to be strongly pursued in as many cases as possible. In addition, we strongly recommend following up all hypospadics, independently of the severity of their genital malformations, through adolescence to early adulthood, to ensure early detection of subjects with impaired psychological profiles.

Analysis of biochemical bone markers as prognostic factors for survival in patients with hormone-resistant prostate cancer and bone metastases.

OBJECTIVES: To investigate the prognostic value of some conventional bone markers and a number of other factors in terms of the survival of patients with hormone-resistant prostate cancer and bone metastases treated with chemotherapy. METHODS: The data of 141 patients were analyzed to verify the influence of the following factors on survival: bone-alkaline phosphatase, type I collagen propeptide, the carboxyterminal telopeptide of type I collagen, the urinary calcium/creatinine ratio, patient age, Karnofsky performance status, pathologic grade, duration of response to primary hormonal therapy, prostate-specific antigen, hemoglobin, lactate dehydrogenase, and extent of bone disease. RESULTS: When all the variables were simultaneously analyzed using the multivariate proportional hazard model, only Karnofsky performance status (P <0.005) and duration of response to primary hormonal therapy (P <0.0001) remained statistically significant. CONCLUSIONS: The results of this study suggest that bone-alkaline phosphatase, type I collagen propeptide, the carboxyterminal telopeptide of type I collagen, and the urinary calcium/creatinine ratio are not prognostic of survival in patients with hormone-resistant prostate cancer and bone metastases treated with chemotherapy.

Weekly low-dose docetaxel in advanced hormone-resistant prostate cancer patients previously exposed to chemotherapy.

OBJECTIVE: The aim of this study was to evaluate the activity and tolerability of docetaxel in patients with hormone-resistant prostate cancer previously exposed to chemotherapy. METHODS: We enrolled 27 patients with hormone-resistant prostatic cancer that had progressed during first-line chemotherapy. The primary end-point was palliative response defined as a 2-point reduction in the 6-point present pain intensity scale, and an improvement in Karnofsky performance status of one 10-point category. The treatment consisted of weekly docetaxel 25 mg/m(2) body surface area administered by means of a 1-hour intravenous infusion with corticosteroid premedication. RESULTS: The primary criterion of palliative response was met in 13 patients (48%) after eight treatment cycles; its median duration was 6 months (range 1-8). Mean global quality of life improved in 8 and 10 patients after respectively four and eight treatment cycles. After a median follow-up of 8 months, 21 patients had died: the median survival was 9+ months (range 2-18). Weekly docetaxel was very well tolerated: grade 3 neutropenia occurred in 1 patient and grade 3 anemia in 2. CONCLUSIONS: Weekly low-dose docetaxel is an effective and well-tolerated treatment for patients with hormone-resistant prostate cancer previously exposed to chemotherapy.
