Small cell lung cancer (SCLC) is a highly aggressive form of lung cancer with limited treatment options. Patients often respond well to initial chemo-immunotherapy but relapse quickly, necessitating new strategies to enhance immune responsiveness. Recent research explores combining DNA-damaging therapies with immunotherapy to activate the STING pathway and improve the antitumor immune response. The addition of DNA Damage Repair (DDR) inhibitors, such as DNA-PKcs inhibitors, after chemotherapy has shown promise in activating innate immune sensors and enhancing CD8+ T cell and NK cell pathways in SCLC models. This approach could potentially reshape the tumor microenvironment and sustain an antitumor immune response, offering a maintenance strategy for SCLC treatment.

Abstract

Small cell lung cancer (SCLC) is a highly aggressive form of lung cancer with limited treatment options. Patients often respond well to initial chemo-immunotherapy but relapse quickly, necessitating new strategies to enhance immune responsiveness. Recent research explores combining DNA-damaging therapies with immunotherapy to activate the STING pathway and improve the antitumor immune response. The addition of DNA Damage Repair (DDR) inhibitors, such as DNA-PKcs inhibitors, after chemotherapy has shown promise in activating innate immune sensors and enhancing CD8+ T cell and NK cell pathways in SCLC models. This approach could potentially reshape the tumor microenvironment and sustain an antitumor immune response, offering a maintenance strategy for SCLC treatment.
