General practitioner questionnaire concerning upper limb lymphedema after breast cancer

Abstract

In France, breast cancer is the most frequent cancer in women. Lymphedema, the main complication, is poorly known. The objective of this study was to assess the state of knowledge of upper limb lymphedema (risk factors, complications, treatment) after treatment of breast cancer among general practitioners from the Haute-Normandie and Île-de-France regions. A cross-sectional study with 23 closed questions was sent by email to 490 practicing doctors. One hundred and sixty-two questionnaires (33%) could be analyzed. Among the participating physicians (men: 55%), 46% were aged over 50 and 75% were from the Haute-Normandie region; 86% of them followed at least 5 women who had breast cancer. Risk factors for lymphedema were: axillary dissection (89%), risk reduction with sentinel lymph node (82%), radiotherapy (81%), mastectomy (45%) and overweight/obesity (42%). For 54% of physicians, lymphedema appeared within 6 months after cancer treatment and was diagnosed upon examination (clinical signs, perimeter measurements) in 78%, without the need for radiological examinations (100%). Physicians with more than 10 years of experience searched for more lymphedema (86% vs. 62%, P<0.0001). Prescriptions included: elastic compression during the day (77%), manual lymphatic drainage (74%), overnight compression (36%) and consultation in a specialized lymphology department (8%). Six percent of physicians had never managed lymphedema and 22% sent patients to an oncologist. Advice given was: prevention of infectious risk (80%), weight loss (42%), avoidance of sports involving the affected limb (22%), and regular arm elevation (14%). Physicians recommended avoiding blood sampling (75%), measuring blood pressure (66%) on the limb ipsilateral to cancer, while 20% did not prohibit any action on the limb. Lymphedema knowledge in general practitioners is generally adequate although the number of women followed by each of them was low. It seems necessary to optimize the training of generalists on lymphedema in order to improve patient management.
