Non-small cell lung cancer (NSCLC) is still the leading cause of cancer-related death, and the treatment of advanced NSCLC relies on systemic treatments. During the last decade, pemetrexed, an antifolate agent, gradually became a key component of the treatment for patients with advanced nonsquamous NSCLC. It has indeed been shown to be efficient for first-line, maintenance and second- or third-line treatment in this subgroup of NSCLC. Moreover, it is usually well tolerated, with few grade 3 and 4 toxicities. Several studies have tried to identify predictive biomarkers of pemetrexed efficacy. Due to pemetrexed's mechanism of action, thymidilate synthase expression predictive value was investigated but could not be demonstrated. Currently, more than 400 trials of pemetrexed for the treatment of nonsquamous NSCLC are ongoing.
非小细胞肺癌(NSCLC)仍然是癌症相关死亡的主要原因,晚期NSCLC的治疗依赖于全身治疗。在过去十年中,抗叶酸剂培美曲塞逐渐成为晚期非鳞状NSCLC患者治疗的关键组成部分。确实已证明它对该亚组NSCLC的一线、维持及二线或三线治疗有效。此外,它通常耐受性良好,3级和4级毒性很少。多项研究试图确定培美曲塞疗效的预测生物标志物。由于培美曲塞的作用机制,对胸苷酸合成酶表达的预测价值进行了研究,但未得到证实。目前,有400多项关于培美曲塞治疗非鳞状NSCLC的试验正在进行。
