Importance In metastatic esophagogastric adenocarcinoma (EGA), the addition of programmed cell death 1 (PD-1) inhibitors to chemotherapy has improved outcomes in selected patient populations. Objective To investigate the efficacy of trastuzumab and PD-1 inhibitors with cytotoxic T-lymphocyte–associated antigen 4 (CTLA-4) inhibitors or FOLFOX in fi...
Article
PURPOSE High pathologic complete response (pCR) rates and comparably good survival data were seen in a phase II trial combining perioperative fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy with trastuzumab for resectable, esophagogastric adenocarcinoma (EGA). The current trial evaluates the addition of trastuzumab and pert...
Article
Background: In the phase 3 KEYNOTE-061 study (NCT02370498), second-line pembro did not significantly prolong OS vs pac in patients with PD-L1-positive (CPS ≥1) GC (N = 395) but did elicit a longer DOR and offered a favorable safety profile. We explored the association between tumor gene expression signatures and clinical outcomes. Methods: In patie...

Article
3503 Background: Planned discontinuation or stop-and-go use of oxaliplatin are established strategies in the systemic therapy of mCRC. Consequently, and irrespective of antibody use, 5FU/LV represents the standard backbone of most maintenance strategies. Unlike VEGF-targeted substances, there is limited evidence that EGFR-antibodies add efficacy to...
