Two historical randomized controlled trials have demonstrated that chemo-radiotherapy offers the best survival advantage over surgery in small cell lung carcinoma (SCLC) and led to abandon surgery for the treatment of SCLC. Yet, widespread use of CT scanning increases the detection of early and very early stage SCLC. Therefore, the traditional 2 stages classification scheme--namely limited and extensive stage disease--is no longer sufficient for such early stage disease and must be completed by the TNM classification. Although randomized controlled trials are lacking, retrospective case series and large population databases suggest a beneficial role of surgery for the earliest SCLC stages. It is thus currently recommended to consider surgery in the multimodal treatment of stage I SCLC.
