Abstract:
The transformation of non-small cell lung cancer to small cell lung cancer (SCLC) is one of the major resistant mechanisms, especially patients with epidermal growth factor receptor mutant lung adenocarcinoma. Translational SCLC has been found to have similar clinical features to primary SCLC. Chemotherapy was short-term effective for transformational SCLC, with a median survival of only about 1 year. The deletion of RB1 and the change of somatic copy number were associated with SCLC transformation. Although the molecular mechanism of SCLC transformation is still not fully understood. At the same time, the treatment of transformational SCLC also faces great challenges. Currently, chemotherapy regimens for SCLC are the main treatment options for transforming SCLC. Combination therapy, local treatment and strategies for prevention of SCLC transformatio are also being explored. This article will review research advances on the clinical features, molecular mechanism and treatment options of translational SCLC.
