Surgical resection with curative intent is the primary therapy for gastric cancer, yet the 5-year survival rate is just 20%. Patients with a DpR of ≥30% had a favorable survival time with nivolumab monotherapy as a later-line treatment. For those with a PD-L1 CPS of 5 or higher who received the combination therapy, the median OS was not achieved. Researchers investigated the potential of an anti-H Pylori treatment after radical gastrectomy to improve survival. Individuals with MLH1, MSH2, and EpCAM PVs were found to have a higher risk of developing GC and DC at the age of 70 years. Dr. Janjigian discusses how the agent - created with invariant natural killer t-cells - works in tandem with other therapies. Dr. Janjigian describes the history behind nivolumab treatment, and the differences in initial results versus follow-up. Results of the PANDA study show that atezo has an additive effect with chemo in eliciting tumor response in early G/GEJ. The study investigated if avelumab and paclitaxel plus ramucirumab would constitute an effective second-line treatment. Dr. Yelena Janjigian discusses the results of the phase 3 MATTERHORN study at ASCO GI 2024. At ASCO GI 2024, new research examined several treatment combinations to determine which combination may improve OS rates. The combination of neoadjuvant/adjuvant pembrolizumab with FLOT is a feasible treatment with no new safety concerns. The benefits of combination neoadjuvant and adjuvant chemotherapy and immune checkpoint inhibition are currently unknown. Researchers sought to determine if a combination of sintilimab and first-line chemotherapy would improve survival rates. The addition of afatinib was found to provide marginal survival benefits, and nivolumab provided a durable survival benefit. Pembrolizumab is now approved with fluoropyrimidine- and platinum-containing chemo for patients with gastric or GEJ cancer. A phase 3 trial sought to determine the impact of HIPEC on overall survival in patients after undergoing CRS. The combined pCR and near-complete pathological response rate was 27% with durvalumab and 14% with chemotherapy alone. Pranob Bhattacharya discusses zolbetuximab, a first-in-class investigational therapy for the treatment of gastric cancer. Daily vitamin D3 supplementation was associated with reduced risk of relapse or death in digestive tract cancer.
