Patients with poor performance status and/or are elderly are frequently considered a compromised group at high risk of chemotherapy-related morbidities and less likely to benefit from treatment. We aimed to evaluate tolerability and efficacy of three single-agent regimens in these patients.
Patients with advanced non-small cell lung cancer who had performance status 2/3 and/or were aged 70 and older were randomly assigned to receive gemcitabine, vinorelbine, or docetaxel. Objective response, toxicities, and quality of life were evaluated.
One hundred thirty-five patients were registered, of whom one was ineligible. Of the 134 patients, 43 received gemcitabine, 45 vinorelbine, and 46 docetaxel. The response rate was 16%, 20%, 22% for gemcitabine, vinorelbine, and docetaxel, respectively. The main grade 3/4 toxicities were fatigue (18%) and neutropenia (16%). There was improvement in global health scores, cough, and dyspnea for all treatment groups. The improvement in dyspnea was most marked in patients with performance status 3.
There was no significant advantage of any of the treatment arms over the rest. There was benefit seen with improvement of quality of life in patients who were able to receive more cycles of chemotherapy.
体能状态差和/或年龄较大的患者常被视为一个处于化疗相关发病高风险的受损群体,且不太可能从治疗中获益。我们旨在评估三种单药方案在这些患者中的耐受性和疗效。
体能状态为2/3且/或年龄在70岁及以上的晚期非小细胞肺癌患者被随机分配接受吉西他滨、长春瑞滨或多西他赛治疗。评估客观缓解率、毒性和生活质量。
登记了135例患者,其中1例不符合条件。在这134例患者中,43例接受吉西他滨治疗,45例接受长春瑞滨治疗,46例接受多西他赛治疗。吉西他滨、长春瑞滨和多西他赛的缓解率分别为16%、20%、22%。主要的3/4级毒性为疲劳(18%)和中性粒细胞减少(16%)。所有治疗组的总体健康评分、咳嗽和呼吸困难均有改善。体能状态为3的患者呼吸困难改善最为明显。
任何一个治疗组相对于其他组均无显著优势。能够接受更多周期化疗的患者生活质量得到改善。
