Standard follow-up program for breast cancer patients

This study follows breast cancer patients who are scheduled to receive radiotherapy at a National Cancer Center in Korea. By collecting information during and after treatment, researchers hope to better understand how patients do over time.

This trial studies a standard follow-up treatment plan that combines chemotherapy and radiation after surgery, and it looks for blood/tissue “biomarkers” that predict who benefits most. If you have high-risk breast cancer that didn’t fully disappear after initial (neoadjuvant) chemo, you may be eligible to help guide better future treatment choices.

This trial uses individual measures of how sensitive your body’s tissues are to radiation to guide after-surgery breast radiation treatment. It aims to keep treatment safe and effective while tailoring the plan to each person.

This trial compares standard follow-up visits versus more intensive follow-up for people with early breast cancer after their main treatment. The goal is to see whether closer monitoring finds problems earlier or improves outcomes.

This trial tests if a 2-week course of radiation after breast cancer surgery works as well as a 3-week course. It may help reduce treatment time for people who have had surgery and some lymph nodes removed.

This study checks how well a previous early breast cancer treatment works over the long term and monitors safety. It may help you and future patients by providing long-term results from the original trial.
