Assessment of Complete Pathologic Response After Neoadjuvant Chemotherapy for Breast Cancer

December 23, 2024 updated by: Masonic Cancer Center, University of Minnesota
This is a feasibility study to gain preliminary information regarding whether breast imaging with or without a core needle biopsy after neoadjuvant chemotherapy (NAC) but before surgery can accurately predict complete pathologic response (pCR) in women with triple negative or HER2- positive breast cancer. pCR is defined as having no residual invasive breast cancer or ductal carcinoma in situ.

No

Sampling Method

Non-Probability Sample

Study Population

Study entry is open to women 18 years of age and older regardless of race or ethnic background. While there will be every effort to seek out and include minority patients, the patient population is expected reflect those at the University of Minnesota with triple negative or HER2+ breast cancer.

Description

Inclusion Criteria:

  • Biopsy proven triple negative (TN) (ER-/PR-/HER2-) or HER2 positive (ERany/PRany/HER2+) breast cancer for which neoadjuvant chemotherapy is planned
  • A biopsy clip placed at the time of diagnostic biopsy
  • 18 years of age or older
  • Must be able to read and write in English due to the importance of survey (questionnaire) completion to meet the study's endpoint - this is justified as there is no individual benefit to study participation
  • Able to provide written consent prior to any research related activities

Exclusion Criteria:

  • Stage IV breast cancer
  • T4 breast cancer
  • Previous ipsilateral breast cancer
  • Any contraindication for undergoing a contrast-enhanced breast MRI and/or the breast biopsy between chemotherapy and surgery
