Core Tip

Core Tip: This work describes a rare case of a KIF5B-RET fusion in small cell lung cancer (SCLC) and the patient's sustained partial response to the 4th line therapy with anlotinib. The study highlights the potential of RET fusions as a promising molecular target in SCLC treatment and emphasizes the importance of next-generation sequencing for personalized therapy options. The innovative arguments include the identification of a novel fusion in SCLC and the potential for targeted therapy to enhance the survival rates of SCLC patients.
