Treatments for non-small cell lung cancer (NSCLC) are based on the broad categories of squamous or non-squamous histology. Frontline treatment options include pemetrexed and cisplatin, pemetrexed and a taxane, gemcitabine with cisplatin, and the addition of bevacizumab to a taxane and carboplatin. Pemetrexed is used for maintenance therapy for non-squamous NSCLC, whereas patients with squamous NSCLC lack easy options for maintenance therapy. nab-Paclitaxel overcomes the solubility and toxicity issues of solvent-based paclitaxel, and the albumin in nab-paclitaxel improves the concentration of the drug in the tumor. A recent phase III trial in NSCLC compared nab-paclitaxel with carboplatin versus solvent-based paclitaxel with carboplatin, and found improved overall response rates (ORRs) in the nab-paclitaxel arm (33% vs 25%; P=.005). In a subset analysis, NSCLC patients with squamous histology had a higher ORR (41%) with nab-paclitaxel than with solvent-based paclitaxel (24%; P<.001). Another subset analysis found that patients ages 70 years and older had improved overall survival (median 19.9 months) with nab-paclitaxel compared with solvent-based paclitaxel (median 10.4 months; P=.009). Patients in the nab-paclitaxel arm had less neuropathy, less hearing loss, and fewer interruptions in daily living than patients in the solvent-based paclitaxel arm.
非小细胞肺癌(NSCLC)的治疗基于鳞状或非鳞状组织学的广泛分类。一线治疗方案包括培美曲塞和顺铂、培美曲塞和紫杉烷、吉西他滨和顺铂,以及在紫杉烷和卡铂基础上加用贝伐单抗。培美曲塞用于非鳞状NSCLC的维持治疗,而鳞状NSCLC患者缺乏简便的维持治疗方案。白蛋白结合型紫杉醇克服了溶剂型紫杉醇的溶解性和毒性问题,且白蛋白结合型紫杉醇中的白蛋白提高了肿瘤内药物浓度。最近一项NSCLC的III期试验比较了白蛋白结合型紫杉醇联合卡铂与溶剂型紫杉醇联合卡铂,发现白蛋白结合型紫杉醇组的总缓解率(ORR)有所提高(33%对25%;P = 0.005)。在亚组分析中,鳞状组织学的NSCLC患者使用白蛋白结合型紫杉醇的ORR(41%)高于溶剂型紫杉醇(24%;P < 0.001)。另一项亚组分析发现,70岁及以上患者使用白蛋白结合型紫杉醇的总生存期有所改善(中位生存期19.9个月),而溶剂型紫杉醇组为(中位生存期10.4个月;P = 0.009)。与溶剂型紫杉醇组患者相比,白蛋白结合型紫杉醇组患者的神经病变、听力丧失较少,日常生活中的干扰也较少。
