Primary purpose: TREATMENT

Brief summary: This study involves patients treated with cisplatin and etoposide (induction therapy), followed by treatment with a drug called S1 (maintenance therapy). The main purpose of this study is to determine if this type of treatment will delay the growth of the tumor and if so, for how long. The primary endpoint is progression free survival and second endpoints are toxicities, overall survival.

Detailed description: Small cell lung cancer (SCLC) accounts for about 20% of lung cancer, has a high degree of malignancy, short doubling time, early and widespread metastasis, is sensitive to chemotherapy and radiotherapy, and has a high initial response rate, but is prone to secondary drug resistance and relapse. The treatment is mainly based on systemic chemotherapy, and if maintenance therapy with S1 after standard EP regimen induction therapy could prolong progression free survival.
