Coming October: SITC releases its late-breaking abstract titles. We’ll add their presenting authors’ institutions to this guide once they’re out.

Dartmouth College at SITC 2026

Nov 4–8, 2026 Phoenix, AZ ~6k attendees Website

Dartmouth College brings 6 presentations to SITC 2026 in Phoenix. Its program centres on how PD-L1 and inflammatory signals help tumors resist treatment, especially in melanoma and bladder cancer. One distinctive item finds that IL-6 signaling makes fat cells display PD-L1, weakening checkpoint drugs.
