To compare the efficacy and toxicity of gemcitabine versus docetaxel in a second-line setting of nonsmall cell lung cancer (NSCLC) patients previously treated with platin-based combination chemotherapy.
We retrospectively evaluated the medical records of 57 patients treated with single agent gemcitabine or docetaxel in second-line setting of advanced NSCLC who received one prior platinum-based therapy.
The mean age was 56.7 ± 8.39 years with 55 ( 96.5%) males and two (3.5%) females. Forty of them received docetaxel and 17 gemcitabine. The mean number of chemotherapy cycles was 6.8 ± 4.0 in the gemcitabine group, while it was 4.6 ± 3.0 in the docetaxel group. Overall response rates were 8% and 12% (P=0.02) for gemcitabine and docetaxel, respectively. The median survival time was 22 versus 21 months for gemcitabine and docetaxel, respectively. The median times to progression were 8 and 5 months. There was no difference between the two groups in terms of incidence of adverse affects (40% vs 47.1%). All of the hematological side effects were grade 1/2. No major toxicity was encountered necessitating stopping the drug for either group.
Treatment with gemcitabine demonstrated clinically equivalent efficacy with a significantly improved safety profile compared with those receiving docetaxel in the second-line setting for advanced NSCLC in this study. Based on these results, treatment with gemcitabine should be considered a standard treatment option for second-line NSCLC.
比较吉西他滨与多西他赛在曾接受铂类联合化疗的非小细胞肺癌(NSCLC)患者二线治疗中的疗效和毒性。
我们回顾性评估了57例在晚期NSCLC二线治疗中接受单药吉西他滨或多西他赛治疗的患者的病历,这些患者之前接受过一次铂类治疗。
平均年龄为56.7±8.39岁,其中男性55例(96.5%),女性2例(3.5%)。其中40例接受多西他赛治疗,17例接受吉西他滨治疗。吉西他滨组的平均化疗周期数为6.8±4.0,而多西他赛组为4.6±3.0。吉西他滨和多西他赛的总体缓解率分别为8%和12%(P=0.02)。吉西他滨和多西他赛的中位生存时间分别为22个月和21个月。中位进展时间分别为8个月和5个月。两组在不良反应发生率方面无差异(40%对47.1%)。所有血液学副作用均为1/2级。两组均未出现需要停药的严重毒性反应。
在本研究中,对于晚期NSCLC的二线治疗,与接受多西他赛治疗的患者相比,吉西他滨治疗显示出临床等效的疗效,且安全性显著提高。基于这些结果,吉西他滨治疗应被视为二线NSCLC的标准治疗选择。
