https://www.cancerresearchuk.org/about-cancer/find-a-clinical-trial/a-study-looking-at-the-management-of-breast-cancer-that-has-come-back-in-the-same-breast-or-nearby#undefined (added 24/03/2022)

Background and study aims
Although the 5-year UK breast cancer survival rate is favourable at 86.6%, patients continue to develop breast cancer recurrence within the same breast after breast-conserving surgery, as well as in the remaining skin or chest wall after mastectomy. Patients also present with breast cancer recurrence in the nearby lymph glands (under the arms or above/below the collarbone). These recurrences are collectively termed locoregional recurrence (LRR). It is estimated that up to 8% of breast cancer patients are diagnosed with LRR 10 years after their diagnosis.
Currently there is a lack of high-quality data and clinical guidance for the optimal management of breast cancer patients diagnosed with LRR. In the UK, breast cancer recurrence is under-reported at the individual hospital level to the national cancer registries. As a result, analysis of existing routine data sources is unlikely to provide data on patient management that is reflective of current national practice.
The aim of this study is determine the frequency, current management and prognosis of patients diagnosed with breast cancer LRR with or without distant metastasis in the UK with the aim of establishing best practice and informing future national guidelines. Over 50 UK breast units will participate in the study.

Who can participate?
Patients aged over 18 years treated for previous breast cancer

What does the study involve?
The researchers will establish a national prospective cohort of patients newly diagnosed with LRR (with or without distant metastasis) and describe how these patients are managed, and examine any geographical variation in the care received. The participants will be followed up at two timepoints (3 and 5 years) in order to determine patient survival outcome (breast cancer related or not), as well as the development of any further locoregional re-recurrence or distant metastasis. Patient survival analysis will identify prognostic factors, which will in turn generate hypotheses for future related studies with an aim of improving patient outcomes.

What are the possible benefits and risks of participating?
The researchers cannot promise that the study will benefit the study participant directly, but the information provided will help to improve the future management of patients diagnosed with breast cancer locoregional recurrence. There are no specific risks related to study participation. Taking part in this study will not change any treatment plans or investigations recommended by the medical team.

Scientific titleThe MARECA study - National study of management of breast cancer locoregional recurrence and oncological outcome
Study acronymMARECA
Study hypothesisFor patients diagnosed with breast cancer locoregional recurrence (LRR), there is clinical uncertainty with regards to what constitutes optimal patient management and if geographical variations exist in patient care. The key areas that require evaluation include radiological staging investigations and the proportion of patients found to have distant metastasis at presentation, surgical management including the use of repeat breast-conserving surgery and sentinel lymph node biopsy, and information about adjuvant treatment modalities used, as well as the patient's subsequent prognosis. Collection of these data will provide a national picture of patient management and enable the identification of clinicopathological factors that predict patient prognosis.

ConditionBreast cancer
InterventionThis is a prospective, observational, multicentre, longitudinal cohort study. This will be a national collaborative research study delivered in collaboration with the Association of Breast Surgery (ABS) Academic and Research committee and the breast surgery and oncology trainee associations (the Mammary Fold and UK Breast Cancer Trainees Research Collaborative Group).

The study will have two main phases:

National prospective cohort study: In 2021, over 50 UK breast units will aim to recruit consecutive eligible patients newly diagnosed with locoregional recurrence (LRR) +/- distant metastasis. The study will recruit patients for 24 months. Eligible patients will be identified at the breast MDT meetings or in breast and oncology clinics. We anticipate each unit to recruit 5 to 10 patients per year. Therefore, the anticipated sample size is 500 patients.

All prospective consecutive patients will be approached and those that fulfil all the eligibility criteria will be given the Patient Information Sheet and given time to read the information and ask any questions about the study. Once the patient has had time to consider the information and ask questions, and if they choose to participate in the study, written informed consent will be obtained. Consent can be taken by the consultant breast surgeon or oncologist, breast surgery or oncology trainees, research nurses, or appropriately trained clinical trials assistants where delegated by the Chief/Principal Investigator. The patient consent will include the permission to collect pseudonymised data on the patient's initial and recurrent cancer treatment. This will include permission to examine the patient's survival and re-recurrence at 3 and 5 years after their LRR diagnosis.

Patients will also be provided with the option of consenting for permission to access archival tumour tissue or slides of the initial and recurrent breast cancer for potential future related tissue substudy. Patients can participate in the main study without consenting to tissue or slide access.

The participating patients will receive standard care and study participation will not result in additional tests, interventions, or clinic visits. Once patient consent has been obtained, consultant breast surgeon or oncologist, breast surgery or oncology trainees, research nurses, or clinical trials assistant will collect data detailing the tumour pathology, imaging results, surgical treatment, radiotherapy, and systemic therapy of initial and recurrent cancer for the study participant. These data are routinely collected as part of standard clinical practice. The study data will be recorded in a pseudonymised format using a secure web-based database (REDCap; hosted at the University of Manchester). This will enable the description of the current national practice including:
1. Modality of radiological staging investigations used and determination of the rate of detection of distant metastasis
2. Proportion of patients undergoing repeat breast-conserving surgery (BCS)
3. Proportion of patients undergoing repeat sentinel lymph node biopsy (SLNB), techniques used, and their success rate in terms of SLN identification
4. Adjuvant treatment modalities used to treat LRR
5. Proportion of patients undergoing breast surgery for LRR in the presence of distant metastasis

Separately, a local secure record will be kept of the RedCap ID with corresponding NHS number (in England and Wales), Community Health Index number (in Scotland), or Health and Care number (in Northern Ireland) for future identification of patients. This is required for the research team at each participating centres to access the hospital electronic system to determine the follow up oncological outcome data for the study participants.

Oncological outcome evaluation: At 3 and 5 year follow up after the LRR diagnosis, the research team at each participating unit (Consultant PI, research nurse, and clinical trial assistants) will also access the hospital electronic system to record survival and re-recurrence outcome for each study participants.

Statistical survival analysis will be performed to determine patient survival and re-recurrence rates for the study cohort. There are planned statistical analyses to determine potential predictive factors that influence patient survival. A power calculation has determined that a subset of 330 patients diagnosed with LRR (without associated distant metastasis at presentation) are required to determine the study’s primary endpoint (disease-free survival following LRR resection, stratified according to the type of surgery performed for the initial breast cancer; BCS and radiotherapy vs mastectomy).

The researchers will not anticipate direct patient contact for the study purpose during this follow up period as all the required information should be available on the hospital electronic system. In cases where the required information is missing or unclear, the research team may contact the patient or their General Practitioner via telephone.
