Leftover tumor after breast cancer treatment: a hidden risk revealed

NCT ID NCT07714382

First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time

Summary

This study looks back at medical records of women with triple-negative breast cancer who had chemotherapy and radiation before surgery. It focuses on those who still had cancer cells left after treatment (residual disease) and tracks how long they lived without the cancer coming back. The goal is to understand which factors are linked to worse outcomes, so doctors can better identify who needs more aggressive follow-up.
