Platinum-based chemotherapy is the standard first-line treatment for patients with advanced non-small-cell lung cancer (NSCLC). However, randomized trials have recently demonstrated the efficacy of several new drugs (pemetrexed, bevacizumab, cetuximab, erlotinib, gefitinib) in this setting. Hence, the choice of optimal treatment is no longer limited to the different platinum-based doublets. In order to guide clinical management of patients with advanced NSCLC, assess the strengths and limitations of available evidence, and to suggest priorities for clinical research, the Italian Association of Thoracic Oncology organized an International Expert Panel Meeting on the first-line treatment of advanced NSCLC, which took place in Sperlonga (Italy) in May 2009. Experts recommended that every effort should be made to obtain adequate tumor tissue before initiating treatment. Tumor histology/cytology subtyping is now important for the correct choice of treatment. In particular, considering efficacy data obtained with pemetrexed and safety concerns with bevacizumab, a division between squamous and non-squamous tumors is necessary. Epidermal growth factor receptor (EGFR) mutation analysis, at present, is not recommended in all patients, but should be performed in subgroups of patients characterized by higher prevalence of sensitizing mutations (Asians, never smokers, women, adenocarcinoma). When a mutation is present, first-line treatment with single-agent EGFR tyrosine-kinase inhibitor may be considered. Finally, the potential benefit of maintenance treatment for patients without progression at the end of first-line should be carefully discussed with each patient. Although the number of treatment options for patients with advanced NSCLC has increased recently, their results remain modest and further research is mandatory.
铂类化疗是晚期非小细胞肺癌(NSCLC)患者的标准一线治疗。然而,最近的随机试验已经证明了几种新药(培美曲塞、贝伐单抗、西妥昔单抗、厄洛替尼、吉非替尼)在这种情况下的疗效。因此,最佳治疗方案的选择不再局限于不同的铂类双联方案。为了指导晚期 NSCLC 患者的临床管理,评估现有证据的优势和局限性,并为临床研究提出优先事项,意大利胸肿瘤协会于 2009 年 5 月在意大利斯佩隆加组织了一次关于晚期 NSCLC 一线治疗的国际专家小组会议。专家们建议,在开始治疗前,应尽力获取足够的肿瘤组织。肿瘤组织学/细胞学亚型分类对于正确选择治疗方法现在很重要。特别是,考虑到培美曲塞的疗效数据和贝伐单抗的安全性问题,有必要将鳞状细胞癌和非鳞状细胞癌分开。表皮生长因子受体(EGFR)突变分析目前不建议在所有患者中进行,但应在具有更高敏化突变发生率的患者亚组中进行(亚洲人、从不吸烟者、女性、腺癌)。当存在突变时,可以考虑一线使用单药 EGFR 酪氨酸激酶抑制剂治疗。最后,对于一线治疗结束时无进展的患者,应与每位患者仔细讨论维持治疗的潜在获益。尽管晚期 NSCLC 患者的治疗选择最近有所增加,但它们的疗效仍然有限,需要进一步研究。
