Skip breast surgery after excellent MRI response

Breast Cancer Invasive

Part of Cancer clinical trials.

This trial tests whether some women with HER2-positive breast cancer can safely avoid breast surgery if their tumor nearly disappears after chemotherapy. It uses MRI and biopsy results to find people most likely to have no remaining cancer (pCR).

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

Who can take part

  • You are a woman age 20 or older
  • Your cancer is invasive ductal carcinoma and HER2 positive
  • You have no spread to distant organs (no distant metastasis)
  • Before treatment, the main tumor was small (≤ 5 cm) and lymph nodes were likely not too advanced (cN0–2)
  • After neoadjuvant chemotherapy, your MRI suggests a very small/near-zero tumor (MRI size ≤ 1.0 cm and a measurement called L-to-B SER ≤ 1.6)

Skipping armpit surgery after good chemo response

This trial tests whether it's safe to skip armpit surgery in people whose breast cancer has responded well to chemotherapy and whose lymph nodes appear cancer-free on ultrasound. It aims to reduce side effects like arm swelling while still controlling the cancer.

NCT06498154Recruiting· Phase 2
Skipping breast surgery for some patients after chemo

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.

Skipping breast surgery after complete response

This trial looks at whether some people with breast cancer can safely avoid breast surgery after they respond completely to treatment before surgery. If you have no remaining cancer in the tissue and lymph node tests, this study checks whether the “watch-and-wait” approach is feasible and safe.

Test to skip breast surgery after chemo

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.

Avoiding extra surgery in women with HER2+ or triple-negative breast cancer

This trial tests whether women with HER2-positive or triple-negative breast cancer who had a complete response to chemotherapy can safely skip radiation or additional surgery. If you had a complete tumor response after chemo and had breast-conserving surgery, you may be eligible.

Omitting surgery for triple-negative breast cancer after complete response

This trial is testing whether some women with triple-negative breast cancer who have a complete response to chemo-immunotherapy can safely skip surgery. It is for women whose cancer completely disappeared after treatment, as shown on MRI and biopsy.
