Vacuum biopsy before surgery to check treatment response
Part of Cancer, Skin clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have signed consent for the study before any study-specific steps
- You have one breast tumor (not multiple areas) confirmed as invasive breast cancer, with specific hormone test results (ER less than 10%)
- Your tumor started between 1 and 5 cm and has no spread to distant organs (M0), with lymph nodes allowed (any N)
- Before chemotherapy, a small marker “clip” was placed at the main tumor location
- After chemotherapy, your MRI scan shows complete or near-complete response (MRI is strongly preferred; ultrasound may be allowed)
- The area of the previous tumor “tumor bed” must be reachable for biopsy before surgery

Other trials that look related to this one.
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.
This trial looks at whether using tumor test results (biomarkers) can help guide the best hormone treatment and chemotherapy before surgery. It focuses on people with stage II or III, ER-positive, HER2-negative breast cancer, with the goal of improving how well the tumor responds before it is removed.
This trial looks at different drug combinations given before surgery to shrink breast tumors. The goal is to find which treatments work best for different types of breast cancer, such as triple-negative, HER2-positive, or hormone-receptor-positive. If you are a woman scheduled for neoadjuvant therapy (treatment before surgery) and have not had previous cancer treatment, this study may be for you.
This trial tests a treatment given before breast surgery to shrink breast cancer and improve outcomes based on your tumor type. Your eligibility depends on tumor size/stage, hormone and HER2 markers, and overall health checks.
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 trial tests whether women with certain aggressive breast cancers (HER2-positive without hormone receptors, or triple-negative) can safely skip breast surgery if chemotherapy makes their tumor completely disappear. The goal is to avoid surgery and its side effects when it may no longer be needed.
