Earlier immunochemotherapy may boost survival in small cell lung cancer

December 10, 2025

A study of 397 patients with extensive-stage small cell lung cancer (ES-SLC) found that receiving immunochemotherapy (atezolizumab or durvalumab plus chemotherapy) before 3:00 pm was associated with significantly better outcomes: a 52% lower risk of progression and 63% lower risk of death compared with later administration.

Clinical takeaway: When scheduling immunochemotherapy for ES-SCLC, consider morning or early afternoon infusions to optimize outcomes.
