Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 4

  1. Breast cohort: 1. Men or women with histologically confirmed invasive breast cancer. a. Patients with synchronous unilateral breast tumours are eligible based on the characteristics of the highest staged tumour. 2. Patients have undergone complete primary invasive tumour excision with clear radial margins as judged by the multidisciplinary team. 3. Surgical staging of the axilla must have been undertaken by sentinel node biopsy, axillary sampling or dissection. 4. In those patients with a positive sentinel node biopsy: a. If 1, 2 or 3 nodes are positive, subsequent management of the axilla (with surgery, radiotherapy or no further intervention) should follow institutional policy. If axillary surgery is to be undertaken, this should be completed prior to registration. b. If 4 or more nodes are involved, patients must have undergone completion axillary node dissection. 5. Radiotherapy: a. Patients who have undergone breast-conserving surgery should receive adjuvant radiotherapy. b. Patients who have undergone mastectomy should receive radiotherapy if they have more than 3 axillary lymph nodes involved. c. Patients who have undergone mastectomy and have T3 tumours and/or 1, 2 or 3 involved lymph nodes may (or not) receive radiation as per institutional practice. 6. Final histology must fall within at least one of these groups: a. For patients not receiving neoadjuvant chemotherapy: i. Node positive, or, ii. Node negative with high-risk features, defined as two or more of:  ER negative (Allred score <3/8 or negative according to institutional criteria)  HER2 positive  Grade 3  Lymphovascular invasion present  Age less than 35  Oncotype Dx score of >25  Prosignia score (PAM50) of >60 -Patients are permitted to have had neoadjuvant endocrine therapy for up to 6 months, as long as final surgical pathology falls within one of the above two groups. -In the above definitions patients with micrometastases should be regarded as node positive. Patients with isolated tumour cells should be regarded as node negative. b. Patients who have received neo-adjuvant chemotherapy or radiotherapy must fall into one of the following 3 categories: i.
