title: Management of recurrent locoregional breast cancer: oncologist survey.
abstract: Locoregional recurrence (LRR) after therapy for early breast cancer is common. A questionnaire was used to assess consensus between breast oncologists about the definition, prognosis and management of patients with LRR. The questionnaire was mailed to surgical, radiation and medical oncologists in Canada, the UK and the USA. Of 495 questionnaires, 322 (65%) were returned. Most clinicians sampled agree that disease in the skin of the chest wall, surgical scar, axilla, ipsilateral breast tumor recurrence (IBTR), infraclavicular lymph nodes, supraclavicular fossa lymph nodes and internal mammary lymph nodes constitute sites of LRR. The sites that were felt to be curable by the majority of respondents were: IBTR, surgical scar, axilla or chest wall. It was for these disease sites that local therapy was generally recommended. Irrespective of the site of recurrence, most respondents surveyed recommend initiation of a new systemic therapy at the time of LRR. While the results of this survey show general agreement regarding the definition of sites of LRR, treatment recommendations vary among oncologists. Due to the variation in sites of recurrence, time since initial diagnosis and prior therapy, the exact prognosis and optimal management of LRR remain undefined. In the absence of randomized prospective trial data, recommendations for local and systemic therapy of LRR will continue to mimic those offered at the time of initial presentation of breast cancer.
