Avoid extra lymph-node radiation for certain node-positive breast cancers

Breast CancerRadiation

Part of Cancer, Skin clinical trials.

This trial tests a way to decide whether you can safely receive less radiation to lymph nodes after surgery for breast cancer that has spread to nearby nodes. If you qualify as “low risk,” the goal is to reduce radiation exposure while keeping cancer control safe.

Summary written for real people, not researchers, by Clin2.

N/A
Enrollment
540 people
Ages
18 years to 70 years
Study type
Interventional

Who can take part

  • You’re 18 to 70 years old, and generally able to do most daily activities (ECOG 0–2).
  • Your surgery pathology confirms invasive breast cancer and specific types of lymph-node involvement (small “micrometastasis” or limited node spread).
  • You had breast-conserving surgery or a full breast removal with reconstruction (not just total mastectomy with only a sentinel node biopsy).
  • You completed at least 4 rounds of standard chemotherapy after surgery (or may skip chemo only for some hormone-receptor/low-risk test results).
  • There’s no sign of spread to distant organs on scans done within 3 months before radiation, and no other breast cancer on the opposite side in the prior 12 months.
  • Your medical records must allow the lab test called “RecurIndex,” using your stored tumor tissue.

Skipping radiation for low-risk node-positive breast cancer

This trial tests whether some women with low-risk breast cancer that has spread to a few lymph nodes can safely skip radiation therapy after surgery. It aims to reduce side effects while keeping the cancer from coming back.

Radiation after surgery for intermediate-risk breast cancer

This trial is testing whether giving radiation to nearby lymph nodes after surgery can help prevent breast cancer from coming back. It is for women with a specific type of breast cancer that has spread to a few lymph nodes but can be removed with surgery.

Radiation to lymph nodes after surgery for higher-risk breast cancer

This trial looks at whether adding targeted radiation to lymph nodes after breast surgery can lower the chance of breast cancer coming back in people with higher-risk, node-negative disease. If you qualify, you may get a planned radiation approach designed for prevention, not treatment of spread.

Shorter radiation after surgery for node-positive breast cancer

This trial tests shorter radiation schedules for people with breast cancer that has spread to lymph nodes or is high-risk. It aims to find a shorter course of radiation that is just as effective after surgery.

NCT07724769Not yet recruiting
Lower radiation dose for breast cancer with no lymph node spread after chemo

This trial tests whether giving less radiation to the lymph nodes is safe and effective for breast cancer patients whose lymph nodes were cancer-free after chemotherapy and surgery. It may mean fewer side effects for you.

NCT05440149Recruiting· Phase 3
Radiation after surgery for certain node-positive breast cancer

This study tests whether giving radiation after breast surgery can improve outcomes for people with breast cancer that has spread to nearby lymph nodes (N1). You may be a candidate if you’ve already had surgery and meet specific details about your lymph nodes and cancer type.
