NCI launches 15-Year checkup for cell therapy volunteers

This study is not testing a new treatment. Instead, it follows people who already received experimental cell therapies (like growing immune cells from their tumors or blood) in earlier NCI Surgery Branch trials. The goal is to monitor their health for up to 15 years, as required by the FDA, to track long-term safety and survival. About 1,150 participants with cancers like melanoma or adenocarcinoma will have regular physical exams and blood tests.
