RESUMO
BACKGROUND: Docetaxel is the most active single agent in the treatment of hormone-refractory prostate cancer (HRPC). Because of the preclinical and clinical evidence of synergy of capecitabine and docetaxel, it was hypothesized that this combination would be active and tolerable in HRPC. PATIENTS AND METHODS: Patients received docetaxel 60 mg/m2 intravenously over 60 minutes on day 1 of each 21-day cycle and capecitabine 1000 mg/m2 administered orally twice daily on days 1-14 of each cycle for a maximum of 8 cycles or until disease progression or intolerable toxicity. Seventy-seven patients were enrolled at 43 US Oncology sites. The median age was 69.3 years (range, 48-86 years); 86% were white, and the Eastern Cooperative Oncology Group performance status scores of 0 and 1 were 49% and 51% respectively. Sixty-nine (90%) patients were evaluated for prostate-specific antigen response. RESULTS: Overall, 41% of patients had a decreased prostate specific antigen level > or = 50%. There were 4 complete responses (6%), 24 partial responses (35%), 29 incidences of stable disease (43%), and 11 incidences of progressive disease (16%). Nine patients has stable disease > or = 6 months and the clinical benefit rate was 54%. The median time to response was 1.5 months (range, 1-16.9 months). The estimated survival at 12 and 24 months (range, < 1-27 months). There were no treatment-related deaths. Grade 3/4 toxicities included neutropenia (50%), leukopenia (22%), hand-foot syndrome (17%), fatigue (11%), and nausea (11%). CONCLUSION: Docetaxel/capcitabine is an active and tolerable combination in HRPC. Toxicity was acceptable and anticipated. Response rate and survival are comparable with other docetaxel combinations.

PURPOSE: Experimental data, both in vivo and in vitro, suggest that the combination of gemcitabine and cisplatin acts synergistically. Within the Southwest Oncology Group, we designed a Phase II trial to test this chemotherapy combination for patients with esophageal cancer. EXPERIMENTAL DESIGN: Patients with metastatic or recurrent esophageal cancer were treated with gemcitabine 1000 mg/m(2) on days 1, 8, and 15, and cisplatin 100 mg/m(2) on day 15. Cycles were repeated every 28 days. The statistical endpoint was overall survival. RESULTS: Sixty-four eligible patients were accrued from 37 institutions. Twenty-six percent of patients had prior chemotherapy. The treatment was generally well-tolerated, with the most common toxicity being neutropenia in 31% of patients. All 64 patients have died. Survival at 3 months was 81%, and at 1 year was 20%. Median survival was 7.3 months. CONCLUSIONS: This regimen is tolerable palliative option for patients with metastatic esophageal cancer.
