Thirty-one patients with carcinoma of the breast with metastases were treated by adrenalectomy-oophorectomy and randomized either for combined chemotherapy, vincristine, fluorouracil, methotrexate and thiotepa, beginning within one week after operation and continuing for three months or no chemotherapy. Statistical analyses were Gehan's modification of the Wilcoxon test for censored data, chi-square tests and life table analysis. Pretreatment characteristics--menopausal status, age, disease-free interval, prior hormone treatment and sites of metastases--of both groups were similar. Objective response occurred in 73 per cent of 11 patients in the treatment. A group compared with 47 per cent of 15 patients in the treatment B group, p greater than 0.50. Median duration to relapse in responders was 16 months in the treatment A group and 15 months in the treatment B group, p greater than 0.50. Median survival was 19 months in the treatment A group and 20 months in the treatment B group, p greater than 0.50. Results were not significant, and inclusion of five patients with less than three months of treatment, did not alter the results. Hence, the group receiving early symptomatic treatment did not show an improved response rate, improved duration of remission or enhanced survival time from ablative treatment.
31例伴有转移的乳腺癌患者接受了肾上腺切除术-卵巢切除术,并随机分为两组,一组在术后一周内开始接受联合化疗(长春新碱、氟尿嘧啶、甲氨蝶呤和噻替派),持续三个月;另一组不接受化疗。统计分析采用Gehan对删失数据的Wilcoxon检验修正法、卡方检验和寿命表分析。两组的预处理特征——绝经状态、年龄、无病间期、既往激素治疗情况和转移部位——相似。治疗A组11例患者中有73%出现客观缓解,治疗B组15例患者中有47%出现客观缓解,p>0.50。治疗A组缓解者的复发中位持续时间为16个月,治疗B组为15个月,p>0.50。治疗A组的中位生存期为19个月,治疗B组为20个月,p>0.50。结果无显著差异,纳入5例治疗时间不足三个月的患者也未改变结果。因此,接受早期对症治疗的组在缓解率、缓解持续时间或消融治疗后的生存时间方面并未表现出改善。
