The European Commission has approved Keytruda in combination with platinum- and fluoropyrimidine-based chemotherapy for the first-line treatment of patients with locally advanced unresectable or metastatic carcinoma of the esophagus or human epidermal growth factor receptor 2 (HER2)-negative gastroesophageal junction (GEJ) adenocarcinoma in adults whose tumors express PD-L1 (Combined Positive Score [CPS] ≥10).
New research led by Friends of Cancer Research demonstrates that decreases in circulating tumor DNA after initiation of treatment are associated with improved overall survival in patients with advanced non-small cell lung cancer treated with immunotherapy or chemotherapy.
