Background Information

Infusion timing may enhance survival in NSCLC treatment.

Timing of neoadjuvant immunotherapy and chemotherapy may impact outcomes in operable non-small cell lung cancer (NSCLC) patients. Patients receiving infusions before 2 PM had better overall survival (89.1% vs. 68.3%) and a trend towards better disease-free survival. Timing of immunotherapy could be a crucial factor in treatment planning for NSCLC. Further research is needed to confirm these findings. Early immunotherapy infusion may improve survival in operable NSCLC.
