Misty Dawn Shields, MD, PhD, of Indiana University Melvin and Bren Simon Comprehensive Cancer Center, shares her perspective on two small cell lung cancer (SCLC) abstracts presented at this year’s meeting. The first focuses on a post hoc analysis of the phase III DeLLphi-304 trial (Abstract 8006), which looked at the intracranial efficacy of tarlatamab in the second line; the second evaluated concurrent thoracic radiotherapy, chemotherapy, and durvalumab in extensive-stage disease (Abstract LBA8005).

François-Clément Bidard, MD, PhD, of Institut Curie, presents final progression-free survival 2 findings from the phase III SERENA-6 trial, which investigated the efficacy of camizestrant, a selective estrogen receptor degrader (SERD), vs continued aromatase inhibition in patients with advanced breast cancer with emergent ESR1 mutations. Earlier reports from the trial showed improved progression-free survival with the SERD (Abstract LBA1007).
Jamie E. Chaft, MD, FASCO, of Memorial Sloan Kettering Cancer Center, discusses findings from ECOG-ACRIN EA5142/ALCHEMIST, a phase III randomized trial that evaluated the efficacy of adjuvant nivolumab after standard-of-care adjuvant therapy in patients with resected lung adenocarcinoma without sensitizing EGFR and ALK alterations and squamous cell carcinoma (Abstract 8000).
