The Keystone Symposia conference, “Tumor Metabolism: New Frontiers in Diet, Microbiome and Beyond,” is scheduled for June 8–11, 2026, and will be held at the INEC Killarney Convention Centre in Killarney, County Kerry, Ireland.

This meeting is designed to broaden the scope of cancer metabolism research by moving beyond tumor-intrinsic metabolism to explore the reciprocal relationship between cancer and whole-body (systemic) metabolism. The educational focus includes the critical roles of the microbiome, diet (including obesity, cachexia, and antioxidants), aging, and other metabolic diseases in controlling tumor development, aiming to generate novel insights and inspire cross-disciplinary collaborations for transformative treatment strategies.
