Small-cell lung cancer (SCLC) is a high-grade neuroendocrine carcinoma, metastatic at the time of initial diagnosis in 70% of cases. Within the 30% of localised tumours only 5% of patients are eligible for surgical treatment according to the recommendations of learned societies. These recommendations are mainly based on old phase II and III randomised prospective trials and more recent registry studies. Surgical care is only possible within a multimodal treatment and essentially concerns small-sized tumours without involvement of hilar or mediastinal lymph nodes. As with non-small cell lung cancer (NSCLC), lobectomy with radical lymph node removal is the recommended procedure to achieve complete tumour resection. Patient selection for surgery includes age, performance status and comorbidity factors. Adjuvant chemotherapy combining Platinum salts and Etoposide for resected stage I tumours is recommended by ASCO, ACCP and NCCN. The precise sequence of neo-adjuvant or adjuvant treatments remains controversial because of the large heterogeneity in clinical practice reported in the studies and the context at the time of SCLC discovery. The 5-year survival rate of patients with early stage disease (pT1-2N0M0) treated by lobectomy and adjuvant chemotherapy is between 30% and 58%, which validates the primary place that surgery must have in these early forms. There is certainly little or even no place for such a therapeutic sequence in locally advanced stages (T3-T4 or N2). However, the stage heterogeneity, as in NSCLC, makes final conclusions difficult. In fact, some registry studies with pairing scores reported a median survival of more than 20 months in N2 SCLC. So, all files of SCLC must be evaluated in a multidisciplinary meeting in order to find the optimal solution for patients with rare and heterogeneous tumours.
小细胞肺癌(SCLC)是一种高级别神经内分泌癌,70%的病例在初诊时已有转移。在30%的局限性肿瘤中,根据学术团体的建议,只有5%的患者符合手术治疗条件。这些建议主要基于旧的II期和III期随机前瞻性试验以及近期的登记研究。手术治疗只能在多模式治疗中进行,主要针对未累及肺门或纵隔淋巴结的小肿瘤。与非小细胞肺癌(NSCLC)一样,推荐行肺叶切除并根治性淋巴结清扫以实现肿瘤的完全切除。手术患者的选择包括年龄、体能状态和合并症因素。美国临床肿瘤学会(ASCO)、美国胸科医师学会(ACCP)和美国国立综合癌症网络(NCCN)推荐对I期切除肿瘤患者采用铂盐和依托泊苷联合辅助化疗。新辅助或辅助治疗的确切顺序仍存在争议,因为研究报告的临床实践存在很大异质性,且SCLC发现时的背景情况也各不相同。接受肺叶切除和辅助化疗的早期疾病(pT1-2N0M0)患者的5年生存率在30%至58%之间,这证实了手术在这些早期病例中必须占据的首要地位。在局部晚期阶段(T3-T4或N2),这种治疗方案肯定几乎没有甚至完全没有用。然而,与NSCLC一样,分期异质性使得难以得出最终结论。事实上,一些配对评分的登记研究报告N2期SCLC的中位生存期超过20个月。因此,所有SCLC病例都必须在多学科会议上进行评估,以便为这种罕见且异质性肿瘤的患者找到最佳解决方案。
