• Female or male, age ≥ 40 • Excised invasive breast cancer with local treatment either completed or planned according to trial guidelines. • ER positive (Allred score ≥3 or H-score ≥10 or > 1% of tumour cells stained positive) as determined by the referring site (in a laboratory meeting NEQAS standards). • HER2 negative (IHC 0-1+, or ISH negative/non-amplified [ratio of HER2/chromosome 17 < 2.00 and copy number < 6]) as determined by the referring site (in a laboratory meeting NEQAS standards). • Axillary lymph node status: i. 1-9 lymph nodes involved and if 1-3 nodes, at least 1 node containing a macrometastasis (i.e. deposit > 2mm diameter) ii. 1-3 lymph nodes involved with micrometastases only (i.e. deposit > 0.2-2mm diameter) AND tumour size ≥ 20mm iii. node negative AND tumour size ≥ 30mm. • Considered appropriate for adjuvant chemotherapy by treating physician. • Patient must be fit to receive chemotherapy and other trial-specified treatments with no concomitant medical, psychiatric or social problems that might interfere with informed consent, treatment compliance or follow up. • Bilateral cancers are permitted provided at least one tumour fulfils the entry criteria and none meet any of the exclusion criteria. • Multiple ipsilateral cancers are permitted provided at least one tumour fulfils the entry criteria and none meet any of the exclusion criteria. • Written informed consent for the study.

• ≥10 involved axillary nodes (with either macrometastases and/ or micrometastases) or evidence for internal mammary node involvement. • ER negative OR HER2 positive/amplified (as determined by the referring site). • Metastatic disease. • Previous diagnosis of malignancy unless: i. managed by surgical treatment only and disease-free for 10 years ii. basal cell carcinoma of skin or cervical intraepithelial neoplasia iii. ductal carcinoma in situ (DCIS) of the breast treated with surgery only iv. lobular carcinoma in situ (LCIS) or lobular neoplasia of the breast. • The use of oestrogen replacement therapy (HRT) at the time of surgery. Patients who are taking HRT at the time of diagnosis are eligible provided the HRT is stopped before surgery. • Pre-surgical chemotherapy, endocrine therapy or radiotherapy for breast cancer. Treatment with endocrine agents known to be active in breast cancer treatment including ovarian suppression is permitted provided this was completed > 1 year prior to study entry. • Commencement of adjuvant treatment prior to trial entry. Short-term endocrine therapy initiated because of, for instance, prolonged recovery from surgery is permitted but must be discontinued at trial entry. • Trial entry more than 8 weeks after completion of breast cancer surgery. • Planned further surgery for breast cancer, including axillary surgery, to take place after randomisation, except either re-excision or completion mastectomy for close or positive/involved margins which may be undertaken following completion of chemotherapy.

It is normal clinical practice to offer several months of adjuvant chemotherapy to patients with early breast cancer who have involved axillary lymph nodes. A recommendation for chemotherapy is incorporated into a number of guidelines. Recently however it has been argued that chemotherapy may have little effect on the subtype of breast cancer that is broadly identified as being hormonally responsive without HER2 gene amplification/HER2 protein overexpression and with a low or intermediate grade. These patients already benefit substantially from hormonal therapies and for many, the addition of chemotherapy is thought to confer no significant additional survival advantage. Conventional clinico-pathological assessment however does not reliably identify those individuals with this breast cancer subtype who can safely avoid chemotherapy. Preliminary evidence however strongly suggests that multi-parameter genomic tests are superior to conventional assessment at identifying patients who will not significantly benefit from chemotherapy despite being at risk of relapse as a result of tumour size or lymph node involvement. The OPTIMA trial seeks to advance the development of personalised treatment of early breast cancer by the prospective evaluation of multi-parameter analysis as a means of identifying those patients who are likely to benefit from chemotherapy whilst sparing those who are unlikely to do so from an unnecessary and unpleasant treatment, and to establish the cost-effectiveness of this approach. The OPTIMA study population would ordinarily be treated with a combination of chemotherapy and endocrine therapy. The trial compares the management of patients using test-directed assignment to chemotherapy with standard management (chemotherapy) in a non-inferiority design. A preliminary phase of the study, OPTIMA prelim, was successfully completed. OPTIMA prelim demonstrated the feasibility of a large scale trial and selected the test technology to be used in the main trial.
