Chinese expert consensus on the diagnosis and treatment of advanced RET fusion-positive non-small cell lung cancer (2023 edition) / 中华肿瘤杂志

ABSTRACT

Lung cancer is the most common cancer and the leading cause of cancer death in China. Non-small cell lung cancer (NSCLC) is the most common histological type of lung cancer. Mutations of driver genes have major impacts on incidence and progression of lung cancer. Advances in molecular biology research and clinical research have promoted the discovery of rare tumor driver genes, as well as the development and application of new targeted drugs. Nearly 1% to 2% of NSCLCs harbor RET fusions, and this patient population may not respond well to traditional treatments like chemotherapy or radiation therapy. After the new highly selective RET inhibitors pralsetinib (BLU-667) and selpercatinib (LOXO-292) entered clinical application, the diagnosis and treatment of RET fusion positive NSCLC has made breakthrough progress. At present, there is a lack of guiding consensus on the standardized diagnosis and treatment of RET fusion-positive NSCLC in China. The Society of Cancer Precision of Chinese Anti-Cancer Association and Lung Cancer Expert Group of Chinese Medical Journal, invited 38 experts form respiratory medicine, medical oncology, oncology radiotherapy and pathology to form a consensus development group. Based on the existing research evidence, combined with China's clinical practice experience, a standardized process for the diagnosis and treatment of advanced RET fusion-positive NSCLC is proposed, including suitable populations and methods for RET gene fusion, treatment drug selection, treatment of resistance to highly selective RET inhibitors, and management of adverse reactions to treatment, with a view to providing guidance for clinicians.
