On September 20, 2026, the 2026 Japanese Society of Internal Medicine Continuing Education Lecture Series, Session B was held at the JR Kyushu Hall on the 9th floor of JR Hakata City. Professor Eishi Baba of our department delivered a lecture entitled “Immunotherapy for Gastrointestinal Cancer.”

In his lecture, Professor Baba discussed recent advances in the treatment of gastrointestinal cancers, including esophageal, gastric, and colorectal cancers, with a particular focus on immune checkpoint inhibitors (ICIs). He also explained treatment strategies based on the molecular characteristics of tumors and biomarkers used to guide therapeutic decision-making.

The lecture also addressed the appropriate management of immune-related adverse events (irAEs) and highlighted the growing importance of multidisciplinary collaboration across a broad range of medical specialties as the indications for ICIs continue to expand and their use in perioperative treatment increases.
