Brief Summary
The aim of this study is to assess whether, omitting further axillary treatment (ALND and ART) for patients with early stage breast cancer and axillary nodal metastases on needle biopsy, who after NACT have no residual cancer in the lymph nodes on sentinel node biopsy, is non-inferior to axillary treatment in terms of disease free survival (DFS) and results in reduced risk of lymphoedema at 5 years.

Outcome Measures
Primary Outcomes (2)
Disease free survival (DFS)
DFS calculated as the time from randomisation until the date of first event of either a loco-regional invasive breast cancer relapse, distant relapse, ipsilateral or contralateral new invasive primary breast cancer or death by any cause or the censor date.
5 years
Patient reported lymphoedema
Lymphoedema is self-reported based on two items from the validated Lymphoedema and Breast Cancer Questionnaire (arm "swelling now" and arm "heaviness in the past year"). Lymphoedema is defined as 'yes' to both questions.
5 years

Study Arms (2)
No axillary treatment
EXPERIMENTALPatients in this arm will not receive axillary treatment (axillary lymph node dissection or axillary radiotherapy). Supraclavicular fossa radiotherapy is not allowed when randomised to this arm.
Axillary treatment
ACTIVE COMPARATORPatients in this arm will receive axillary treatment. Axillary treatment can be axillary lymph node dissection or axillary radiotherapy.
Interventions
Breast or chest wall radiotherapy will be delivered as per the Radiotherapy Trials Quality Assurance (RTTQA) guidelines.
Participants will undergo removal of at least level I and II axillary lymph nodes.
Axillary radiotherapy will be delivered as per the Radiotherapy Trials Quality Assurance (RTTQA) guidelines.
Eligibility Criteria
You may qualify if:
- Age ≥ 18
- Male or female
- cT1-3N1M0 breast cancer at diagnosis (prior to NACT) as per AJCC 8th edition (see Section 6.4.1)
- o Patients with occult primary invasive breast cancer (no identifiable invasive cancer in the breast) with FNA or core biopsy proven nodal metastases are eligible for the study.
- FNA or core biopsy confirmed axillary nodal metastases at presentation
- Oestrogen receptor and HER2 status evaluated on primary tumour
- Received standard NACT as per local guidelines (Patients undergoing neoadjuvant endocrine therapy as part of another clinical trial are eligible)
- Imaging of the axilla, as required, to assess response to NACT (per local guidelines)
- Undergo a dual tracer sentinel node biopsy (SNB) after NACT with at least 3 nodes removed.
- If a single tracer SNB is performed: the patient is eligible only if the involved node is marked before or during NACT, and at least 3 nodes (including the marked node) are removed during sentinel node biopsy.
- If the node is not marked or the marked node is not removed: the patient is eligible only if the histology report shows evidence of down-staging with complete pathological response e.g., fibrosis or scarring in at least one node and at least 3 nodes removed.
- If fewer than 3 nodes are found on histology: the patient is eligible only if BOTH points a) and b), below, are met:
- involved node was marked and removed during SNB; and
- removed marked node shows evidence of downstaging on histology e.g. fibrosis or scarring.
- If the sentinel node(s) cannot be localised on SNB: axillary node sampling should be performed, the patient will be eligible if at least 3 nodes are removed.
- +3 more criteria
You may not qualify if:
- Participants will be excluded if they have any one of the following:
- Bilateral synchronous invasive breast cancer
- Sentinel node biopsy prior to NACT
- Previous axillary nodal surgery on the same body side as the scheduled targeted sampling
- Any previous cancer within last 5 years or concomitant malignancy except
- basal or squamous cell carcinoma of the skin
- in situ carcinoma of the cervix
- in situ or stage 1 melanoma
- contra- or ipsilateral in situ breast cancer
- chronic lymphocytic leukaemia not on treatment
