多西他赛联合多柔比星治疗一线化疗失败的非小细胞肺癌Ⅱ期临床研究

目的 观察国产多西他赛注射液联合多柔比星治疗经一线化疗失败的非小细胞肺癌(NSCLC)的临床疗效及毒副反应,并对安全性进行评估.方法 对88例经含铂类药物化疗后进展的NSCLC患者,使用多柔比星40mg/m2静脉冲人,第1天;国产(试验组)或进口(对照组)多西他赛注射液70 mg/m2静脉滴注,第2天.21d为1个周期,治疗3个周期.试验中不预防使用粒细胞集落刺激因子.用世界卫生组织(WHO)的疗效及抗肿瘤药物急性及亚急性毒性反应分度标准评价疗效及毒性,卡式评分评价身体状况变化.结果 88例人组受试者中,81例可评价疗效.试验组和对照组均未出现CR患者,试验组PR、NC和PD患者分别为7、26和8例,对照组分别为3、26和11例.试验组和对照组有效率分别为17.1%和7.5%,临床获益率分别为80.5%和72.5%.两组近期疗效差异无统计学意义.试验组与对照组的不良反应均主要表现为骨髓抑制、脱发及消化道反应等,未见水纳潴留,两组近期疗效差异无统计学意义.结论 国产多西他赛注射液可用于含铂类药物化疗后进展的NSCLC的治疗,疗效显著,耐受性良好.

A randomized phase Ⅱ trial of docetaxel and doxorubicin in treatment for patients with non-small-cell lung cancer who have failed previous platinum-based chemotherapy

Objective The aim of this study was to evaluate the efficacy, toxicity and safety of doxorubicin combined with domestically produced docetaxel versus with taxotere, and to investigate whether these two regimens result in similar outcomes in the treatment for non-small-cell lung cancer (NSCLC) patients who failed previous platinum-bused chemotherapy. Methods Eighty-eight NSCLC patients were enrolled into this clinical phase Ⅱ trial. The patients randomly received either domestic docetaxel (study arm) or taxotere (control arm) at a dose of 70 mg/m2 on D2, while doxorubicin at a dose of 40 mg/m2 onD1 was administered in both groups. It was repeated every 3 weeks, totally for three cycles. No granulocyte colony-stimulating factor was used to prevent granulocytopenia. The response rate and toxicity were evaluated using World Health Organization toxicity scale and Karnofsky performance status scale. Results Of the 88patients, 81 were evaluable in terms of efficacy. There was no complete responder in this series. The response rate (RR) was 17.1% in the study arm versus 7.5% in the control arm, and the clinical benefit rate (CBR) was 80.5% in the study group versus 72.5% in the control group. The most frequent grade 3 or4 toxicities were neutropenia, leucopenia and gastrointestinal symptoms. Other toxicities such as alopecia and vomiting were mild and generally well tolerated. No fluid retention was noticed. Conclusion The administration of doxorubicin 40 mg/m2 on D1 combined with domestic docetaxel 70 mg/m2 on D2 is proved to be as effective and tolerable as with taxotere. The domestic drug docetaxel may be considered as an alternative for patients with non-small-cell lung cancer who failed previous platinum-based chemotherapy.
