Temporal Immunologic Changes With Hypofractionated Radiation-Induced DNA Damage in Breast Cancer

United States36 participantsStarted 2023-09-15

Plain-language summary

This study assesses changes to the immune cells following hypofractionated radiation-induced DNA damage in breast cancer patients. Radiation therapy may cause immune cells to enter tumors and target cancer cells. The goal of this study is to measure the change in the level of immune cells in the tumor before and after radiation therapy.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients \>= 18 years of age with biopsy proven invasive breast cancer * Breast cancer that appears to be superficially accessible to a tumor punch biopsy * Patients thought to derive clinical benefit from palliative RT to the breast/chestwall * In discussions with the medical oncologist, if clinically reasonable, systemic therapy will be held during RT Exclusion Criteria: * A history of prior radiation to the area requiring radiation for which the attending physician believes reirradiation could not be safely delivered * Pregnancy * Active usage of anticoagulant medications that are considered to pose an increased risk of tumor punch biopsies * Receipt of immunotherapy or chemotherapy 7 days prior to start of RT

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
