摘要:
This prospective trial aimed to evaluate the therapeutic effects and systemic toxicities of capecitabine monotherapy and capecitabine treatment combined with biological response modifiers in patients with metastatic renal cell carcinoma. Fifty-four patients suffering from metastatic renal cell carcinoma progressing under first-, second- or third-line treatment entered the trial. Capecitabine was given orally at a dose of 2500 mg/m2daily divided into two doses for 14 days, followed by a 7-day rest in the monotherapy as well as in the combination treatment. This schedule was repeated in 3-week cycles. The combination therapy consisted of capecitabine and an immunotherapy treatment, which consisted either of interferon (IFN)-&ggr;1b (100 mg/day) administered consecutively 5 times weekly during weeks 1 and 2, and recombinant interleukin (IL)-2 (4.5 MU/day) administered on 4 consecutive days during weeks 3 and 4, every 6 weeks, or IFN-&agr; (6 MioIE/day) administered 3 times a week. Fifty-two patients are now evaluable for response and 54 patients for toxicity. We observed a partial response to treatment in five patients (9.6%), minor response in five patients (9.6%), stable disease in 32 patients (61.6%) and only 10 patients (19.2%) showed continued disease progression despite treatment. Outpatient capecitabine was well tolerated. We did not observe any WHO grade IV toxicities. We conclude that capecitabine monotherapy and capecitabine treatment in combination with biological response modifiers appear to be effective regimens with favorable toxicity profiles in patients with advanced renal cell carcinoma. Capecitabine monotherapy seems to be superior than the combination treatment because of its easier application form.
