Immunotherapy has changed the treatment pattern of extensive-disease SCLC (ED-SCLC), but the beneficiary population is limited.

SCLC is characterized by highly active glycolytic metabolism and pyruvate kinase M1 (PKM1) is one of the isozymes of PK, an important rate-limiting enzyme in glycolysis pathway. Previous studies have shown that PKM1 is related to autophagy and drug sensitivity, however, how PKM1 regulates drug sensitivity in SCLC and its mechanism remain unclear.
