Biomarker-guided treatment for early breast cancer before surgery

Breast CancerCancer of the Breast

Treatments studied

Part of Cancer, Skin clinical trials.

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.

Who can take part

  • You have newly diagnosed stage II or III breast cancer (not spread to distant organs).
  • Your tumor is ER-positive (ER more than 10%) and HER2-negative (tested by IHC or FISH showing 0–1+).
  • You plan to have the breast tumor surgically removed after the pre-surgery (neoadjuvant) treatment, and have measurable or large enough disease on scans.
  • You are postmenopausal and can do usual pre-surgery treatments your doctor recommends (an aromatase inhibitor and anthracycline/taxane chemotherapy).
  • Your health is good enough for treatment (ECOG 0–1) and your blood counts/organs are within safe ranges.
  • You can safely complete breast MRI with IV contrast.

NCT07300215Not yet recruiting· Phase 2
Personalized treatment before surgery for early HR+/HER2+ breast cancer

This trial tests whether a customized treatment plan given before surgery can improve outcomes for women with early-stage HR-positive, HER2-positive breast cancer. The goal is to shrink the tumor and make surgery more effective.

NCT05582499Recruiting· Phase 2
Neoadjuvant treatment study for certain breast cancers

This Phase 2 study tests a “precision platform” approach—treatment before surgery—based on specific test results from your breast tumor. It may help determine whether the treatment plan works better for people with particular breast cancer subtypes and healthy organ function.

Comparing breast cancer treatments before surgery

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.

Neoadjuvant treatment for breast cancer before surgery

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.

Hangzhou, Zhejiang
NCT05131893Not yet recruiting
Neoadjuvant treatment before breast surgery for cancer

This trial studies treatments given before surgery for invasive breast cancer, aiming to shrink the tumor so surgery can be done more effectively. It may help some people need breast-conserving surgery or improve the chance of complete cancer removal.
