Zev A. Wainberg, MD, on Gastric or Gastroesophageal Junction Adenocarcinoma: Follow-up Data on Pembrolizumab and Chemotherapy
2022 ASCO Gastrointestinal Cancers Symposium
Zev A. Wainberg, MD, of the University of California, Los Angeles, discusses an update, of 25 additional months, on phase III safety and efficacy results from the KEYNOTE-062 trial. This study compared pembrolizumab with or without chemotherapy vs chemotherapy alone for patients with PD-L1–positive advanced gastric or gastroesophageal junction adenocarcinoma (Abstract 243).

Kohei Shitara, MD, of Japan’s National Cancer Center Hospital East, discusses a long-term data follow-up from CheckMate 649, which support the continued use of nivolumab plus chemotherapy as first-line treatment in patients with advanced gastric, gastroesophageal junction, and esophageal adenocarcinomas (Abstract 240).

Melissa Amy Lumish, MD, of Memorial Sloan Kettering Cancer Center, discusses new findings showing a 100% complete response rate to PD-1 blockade alone among the first 11 patients with locally advanced mismatch repair–deficient rectal cancer treated with this approach. None of the patients required chemoradiation or surgery, thus avoiding their attendant morbidities, and so PD-1 blockade may represent a new treatment paradigm. Follow-up on the durability of response is needed (Abstract 16).

Thierry André, MD, of Sorbonne University and Saint-Antoine Hospital, discusses phase II results from the GERCOR NEONIPIGA study, which suggests neoadjuvant therapy with nivolumab and ipilimumab may be associated with a high pathologic complete response rate in patients with localized microsatellite instability–high or mismatch repair–deficient esophagogastric adenocarcinoma. This study raises the question of whether surgery could be delayed or avoided for some patients (Abstract 244).

Nilofer Saba Azad, MD, of Johns Hopkins Sidney Kimmel Cancer Center, assesses the findings from the phase III TOPAZ-1 trial, a study of durvalumab in combination with gemcitabine plus cisplatin in patients with advanced biliary tract cancer. Dr. Azad explains why the study sets a potential new standard of care of gemcitabine plus cisplatin and durvalumab in unselected patients.

Van K. Morris, MD, of The University of Texas MD Anderson Cancer Center, discusses phase I/II data suggesting that encorafenib plus cetuximab and nivolumab is safe and well tolerated for patients with microsatellite-stable BRAF V600E–mutated metastatic colorectal cancer (Abstract 12).
