| pubmed-article:18606594 | pubmed:abstractText | Hormone-refractory prostate cancer (HRPC) is a rapidly progressive disease which produces considerable morbidity and involves mostly men over 70, often comorbid and with poor tolerance to chemotherapy. Low-toxicity chemotherapy is a reasonable option in this setting. Vinorelbine and a corticosteroid show activity and clinical benefit responses in HRPC. An oral regimen is preferable for elderly patients. This study aimed to evaluate safety, prostate-specific antigen (PSA) response, clinical benefit and progression-free survival in chemonaive elderly HRPC patients. 33 men, median age 78.2, were treated with oral vinorelbine 60 mg/m2 days 1 and 8 every 3 weeks, escalable to 80 mg/m2 after the first cycle, and prednisone 5 mg b.i.d. The main toxicity was hematopoietic (mild at 60 mg/m2 and moderate at 80 mg/m2). Of 27 evaluable patients, 9 (33%) had PSA responses and 9 had clinical benefit, PSA-correlated in 5 cases (56%). Median progression-free survival was 13.4 weeks, median overall survival 45 weeks. Oral vinorelbine plus prednisone is safe and has moderate activity, with biochemical and clinical responses in about one-third of patients and could be an option in unfit elderly HRPC patients. | lld:pubmed |
