Administering docetaxel weekly at a relatively low dose minimizes myelosuppression and reduces nonhematologic toxicities. In a community-based phase II trial conducted in 39 elderly or poor performance status patients with advanced non--small cell lung cancer, weekly 36 mg/m(2) docetaxel produced a response rate of 20%. The response rate was 26% in patients with an Eastern Cooperative Oncology Group performance status of 0 or 1. Actual 1-year survival was 28% and actuarial 2-year survival was 15%. These results are similar to those achieved with other active single agents. The regimen of weekly docetaxel used was associated with minimal hematologic toxicity. There were no cases of grade 4 leukopenia, febrile neutropenia, toxicity-related hospital admissions, or treatment-related death. Nonhematologic toxicities were also mild, even in performance status 2 patients. In a subsequent phase II trial, a similar group of patients received weekly docetaxel at 30 mg/m(2) plus weekly gemcitabine 800 mg/m(2), both drugs given on days 1, 8, and 15 every 28 days. Preliminary analysis of data for the first 41 patients enrolled show an objective response rate of 29%, with an additional 45% of patients having stable disease. Although 26% of patients missed the day 15 dose of gemcitabine and docetaxel because of myelosuppression, the combination regimen was generally well tolerated. There were no hospitalizations caused by complications of myelosuppression. One patient developed bilateral pulmonary infiltrates, possibly treatment-related, and died of respiratory failure. Further evaluation of weekly docetaxel-based combinations is indicated. Semin Oncol 28 (suppl 9):21-25.
以相对低剂量每周给予多西他赛可将骨髓抑制降至最低,并减少非血液学毒性。在一项针对39例老年或身体状况较差的晚期非小细胞肺癌患者进行的基于社区的II期试验中,每周给予36 mg/m²多西他赛的缓解率为20%。东部肿瘤协作组身体状况评分为0或1的患者缓解率为26%。实际1年生存率为28%,精算2年生存率为15%。这些结果与其他活性单药治疗所取得的结果相似。所采用的每周多西他赛方案血液学毒性极小。没有4级白细胞减少、发热性中性粒细胞减少、毒性相关住院或治疗相关死亡的病例。即使是身体状况评分为2的患者,非血液学毒性也很轻微。在随后的一项II期试验中,一组类似的患者每28天在第1、8和15天接受每周一次30 mg/m²多西他赛加每周一次800 mg/m²吉西他滨治疗。对首批入组的41例患者的数据初步分析显示客观缓解率为29%,另有45%的患者病情稳定。尽管26%的患者因骨髓抑制而错过第15天的吉西他滨和多西他赛剂量,但联合方案总体耐受性良好。没有因骨髓抑制并发症导致的住院情况。1例患者出现双侧肺部浸润,可能与治疗有关,死于呼吸衰竭。有必要对基于每周多西他赛的联合方案进行进一步评估。《肿瘤学 Seminars》28(增刊9):21 - 25。
