abstract
OBJECTIVES: Although chemotherapy and radiotherapy are recommended for patients with limited disease small cell lung cancer (LD-SCLC), several series have reported favorable survival outcomes even in patients with stages II and III disease who underwent surgical resection. The purpose of this study is to compare the outcomes of the use of surgical resection to the other conventional non-surgical treatments in patients with LD-SCLC with respect to each clinical stage. MATERIALS AND METHODS: We retrospectively reviewed 277 patients who received treatment for LD-SCLC and compared the outcomes of the use of surgical resection to the other conventional non-surgical treatments. RESULTS: The clinical stage was stage I in 50 cases (18%), stage II in 53 cases (19%) and stage III in 174 cases (63%). Eighty-eight patients received surgical resection and 189 patients were treated with non-surgical treatment. Surgery was performed in 44 patients (88%) with stage I, 27 patients (52%) with stage II and 17 patients (10%) with stage III disease. The five-year survival rates of the patients according to clinical stage were 58% in stage I, 29% in stage II and 18% in stage III. The five-year survival rates of the patients with and without surgical resection according to clinical stage were as follows: 62% and 25% in stage I (p<0.01), 33% and 24% in stage II (p=0.95), 18% and 18% in stage III (p=0.35), respectively. In 44 propensity score-matched pairs with stages II and III disease, including matching for variables such as age, gender and the PS, the five-year survival rates was better in patients with surgical resection than in those without surgery (p=0.04). CONCLUSION: Surgical resection is effective for the patients with stage I LD-SCLC and some cases of stage II or III disease.
