Who may and may not be able to join

AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI

Who may be able to join

  • Women diagnosed with a specific type of invasive breast cancer (called non-special type mammary carcinoma), across any of its main subtypes (luminal, triple-negative, or HER2-positive).
  • People for whom doctors have recommended chemotherapy given before surgery (known as neoadjuvant chemotherapy).
  • People who had a small marker clip placed into the tumor before starting pre-surgery chemotherapy.
  • People whose cancer has been staged as a certain early-to-intermediate range (cT1–T3, N0–N1, M0), assessed through physical examination, mammogram, breast MRI, CT scan of the chest, abdomen and pelvis, and a bone scan.
  • People who, after completing pre-surgery chemotherapy and before surgery, show either a complete response with no visible cancer remaining on scans, or a remaining tumor measuring 2 cm or less on mammogram and MRI.

Who may not be able to join

Each point below is a reason the trial team may not be able to accept someone. It is not a list of requirements to meet.

  • People whose cancer appears in more than two separate locations in the breast (multicentric tumors).
  • People currently taking blood-thinning medications (anticoagulants).
  • People who have extensive calcium deposits in the breast area larger than 2 cm.
  • People who are pregnant.
  • People who are not planning to have surgery as part of their treatment.
  • People who have had another cancer diagnosis within the last 5 years.
  • People whose marker clip has moved away from the original tumor site and no remaining tumor can be seen on imaging in that area (confirm with trial site).
