Treatment of small cell lung cancer (SCLC) is based on the stage of disease. While combination of chemo- and radiotherapy preferably as concomitant chemoradiotherapy represents standard treatment in patients with locally advanced tumors (UICC stage I-III), patients with metastatic disease (stage IV) should be treated with an established platinum based chemotherapy regimen. After chemotherapy and in case of an achieved tumor response treatment should be completed by an adjuvant radiation of the brain in patients with adequate performance status. In patients with a very early stage of disease without involvement of lymph node metastasis a surgical approach in combination with an adjuvant chemotherapy can be discussed. In patients with relapsed tumors second line therapies like the topoisomerase I inhibitor Topotecan have proven efficacy.
Up to now neither molecular targeted therapies nor cytotoxic or immunological maintenance strategies have provided any benefit to patients with SCLC.
