Early immunotherapy improves chances of survival in lung cancer
A study by Central South University in China shows that the timing of immunotherapy has a significant impact on treatment outcomes for advanced small cell lung cancer. The results were published in the journal CANCER of the American Cancer Society.

The researchers studied 397 patients who received the immunotherapy drugs atezolizumab or durvalumab in combination with chemotherapy between May 2019 and October 2023. It was found that patients treated before 3:00 p.m. had significantly longer progression-free survival and overall survival. After accounting for influencing factors, early administration was associated with a 52% lower risk of disease progression and a 63% lower risk of death.
The circadian rhythm, which controls physiological processes such as immune responses, could be the cause of the difference in effectiveness. Study leader Yongchang Zhang emphasizes that adjusting the infusion timing is a cost-effective and easy-to-implement measure that can improve treatment protocols. The results could have immediate clinical relevance for the treatment of small cell lung cancer.
