目前多数治疗手段（包括化疗）对转移性肾癌效果均不理想，人们将希望寄予生物疗法，尽管非随机试验表明干扰素生物疗法能减少转移瘤数目，但争议颇大。多数临床医生认为这种疗法效果不好。为此，作者研究了α干扰素对转移性肾癌病人生存期的影响。在多中心随机试验中，选择 Most current treatments, including chemotherapy, are not effective in metastatic renal cell carcinoma and one would expect to place them on biological therapies. Although non-randomized trials have shown that interferon biotherapy can reduce the number of metastases, there is considerable controversy. Most clinicians consider this treatment ineffective. To this end, the author studied the α interferon on the survival of patients with metastatic renal cell carcinoma. In a multicenter randomized trial, select
