Biopsy after breast cancer chemotherapy treatment
Part of Cancer, Skin clinical trials.
This study tests whether doctors can safely take a small tissue sample from breast tumors after chemotherapy to see what remains before surgery. It may help doctors better understand how tumors respond to treatment and plan the best surgical approach.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman with invasive breast cancer (any type: hormone-receptor positive, triple-negative, or HER2-positive)
- Your doctor recommended chemotherapy before surgery to shrink your tumor
- A small marker clip was placed in your tumor before chemotherapy started
- Your cancer was diagnosed as stage 1–3 (T1–T3, N0–N1, M0) with no spread to distant organs
- After chemotherapy, imaging shows either no tumor remaining or a remaining tumor smaller than 2 cm
- You are planning to have surgery to remove remaining breast tissue

Other trials that look related to this one.
This trial studies a special vacuum-assisted biopsy taken just before breast surgery to see how well pre-surgery (neoadjuvant) chemotherapy worked. It may help doctors understand whether patients truly had a complete or near-complete response on scans, which can guide next steps.
This study checks whether a blood test that looks for “tumor DNA” (circulating tumor DNA) can help evaluate how well neoadjuvant chemotherapy worked for breast cancer. It may help doctors better understand treatment response after surgery.
This study tests a scanner (Histolog®) that checks the edges of removed breast tissue during surgery to make sure all cancer is removed. The goal is to reduce the need for a second surgery.
This study tests a new blood test to see if it can find tiny bits of tumor DNA after chemotherapy. If you have a larger or higher-risk breast cancer and are getting chemotherapy before surgery, you may join. The test could help doctors know if your cancer is gone or if more treatment is needed.
This trial checks if a breast biopsy can confirm that chemo has destroyed all cancer cells, so you might avoid surgery altogether. It's for people with aggressive breast cancer types who responded well to chemotherapy.
This study looks at breast cancer samples taken by biopsy to see how tissue “molecular markers” relate to how you respond to therapy and how the cancer behaves. It may help researchers better match future treatments to the biology of your tumor.
