Gastrointestinal Cancers

Treatment with nivolumab (Opdivo) plus ipilimumab (Yervoy) in the neoadjuvant setting plus adjuvant nivolumab resulted in a high rate of pathologic complete response (pCR) in patients with resectable microsatellite instability (MSI)/mismatch repair deficient (dMMR) oeso-gastric junction (OGJ) adenocarcinoma, according to findings from the GERCOR NEONIPIGA clinical trial, which were presented by Thierry André, MD, Professor, Medical Oncology, Sorbonne Université, Hôpital Saint Antoine, Paris, France, at the 2022 ASCO Gastrointestinal Cancers Symposium.

Early results from the CheckMate-648 clinical trial, which evaluated the efficacy and safety of Opdivo (nivolumab), a PD-1 inhibitor, plus Yervoy (ipilimumab), a CTLA-4 inhibitor, or nivolumab plus chemotherapy, suggest a potential new standard of care for the first-line treatment of patients with advanced esophageal squamous-cell carcinoma (ESCC). These findings were presented at the ASCO 2021 virtual annual meeting by Ian Chau, MD, Consultant Medical Oncologist, Gastrointestinal and Haemato-Oncology, Royal Marsden Hospital, Sutton, United Kingdom, and lead investigator of the trial.

Gastrointestinal (GI) malignancies account for 26% of the global cancer incidence and 35% of all cancer-related deaths.1 There is an urgent need for new therapeutic options for patients with advanced disease beyond the standard, highly burdensome combinatorial approach of polychemotherapy, radiotherapy, and surgery.1 Recent advances in tumor molecular profiling are transforming the therapeutic landscape for patients with GI cancers, allowing for prognostication and predictive risk assessment, as well as more individualized regimens that can extend survival while minimizing the side effects that have long been associated with existing “legacy” treatment options.
