Chemo plus immunotherapy before and after surgery for bile duct cancer
This trial tests a combination of chemotherapy (gemcitabine and cisplatin) and an immunotherapy drug (pembrolizumab) given before and after surgery for people with bile duct or gallbladder cancer that can be removed. The goal is to see if this approach helps prevent the cancer from coming back.
Baltimore, MarylandAges 18 years+ - NCT06002425Recruiting
AI guidance for stomach and colorectal cancer treatment
This study uses a computer program (like ChatGPT) to help doctors recommend the best treatments for people with stomach or colorectal cancer. All your care must happen at one of the study hospitals.
