Yasunobu Ishizuka, MD, on Gastric Cancer: Does Nivolumab Infusion Time of Day Matter?
2024 ASCO GI Cancers Symposium
Yasunobu Ishizuka, MD, of Japan’s Aichi Cancer Center, discusses study results showing that scheduling infusions of nivolumab monotherapy before mid-afternoon for patients with metastatic gastric cancer may alter treatment efficacy. Several studies have suggested that circadian rhythm is essential in immune system function, including anticancer immunity (Abstract 268).

Anant Ramaswamy, DM, of Tata Memorial Centre, discusses phase III results of a study that added docetaxel to a doublet regimen of fluorouracil or capecitabine and oxaliplatin, which did not improve overall survival in patients with advanced gastroesophageal junction and gastric cancers. Continuing chemotherapy beyond 6 months also did not appear to improve survival in this population (Abstract LBA248).

Jennifer Yon-Li Wo, MD, of Massachusetts General Hospital, discusses the local failure rate of non-ablative hypofractionated radiation therapy in combination with the immune checkpoint inhibitors ipilimumab and nivolumab compared to ablative SBRT to treat metastatic microsatellite-stable colorectal and pancreatic cancers as a secondary analysis of four prospective trials. Dr. Wo and her team found that, despite using nearly half the radiation dose in those who received immunotherapy, there was no significant difference in local failure rates (Abstract 752).

Manish A. Shah, MD, of Weill Cornell Medical College, discusses phase III findings of the KEYNOTE-590 study, which shows that, after 5 years, the use of pembrolizumab plus chemotherapy improved survival with durable efficacy, compared with placebo plus chemotherapy, in patients with untreated advanced esophageal cancer (Abstract 250).

Lorraine A. Chantrill, PhD, MBBS, of Australia’s Wollongong Hospital, New South Wales, discusses phase II findings on the combination of nab-paclitaxel plus carboplatin as a first-line treatment for patients with gastrointestinal neuroendocrine carcinomas. According to Dr. Chantrill, this regimen appears to be active in these tumors and warrants further evaluation in a phase III trial (Abstract 589).

Ian Chau, MD, of The Royal Marsden Hospital, discusses reportedly the first study to evaluate the real-world effectiveness of nivolumab as a first-line treatment of advanced gastric, gastroesophageal junction, or esophageal adenocarcinoma. The combination therapy improved overall survival compared with chemotherapy alone. Dr. Chau presents the 18-month follow-up results (Abstract 295).
