Patient education for breast cancer-related lymphedema: a systematic review

The aim was to identify the impact of the (a) components of breast cancer-related lymphedema (BCRL) educational content, (b) modes of education, and (c) timing of education on arm volume, quality of life, function, complications associated with BCRL, adherence to interventions, and knowledge acquisition in individuals diagnosed with breast cancer (BC).

This review followed the Preferred Reported Items for Systematic Review and Meta-analysis (PRISMA) guidelines (PROSPERO CRD42021253084). Databases searched included PubMed, CINAHL, Web of Science, Google Scholar, and Scopus from January 2010 to December 2021. Study quality and bias were assessed using the American Physical Therapy Association's Critical Appraisal Tool for Experimental Intervention Studies.

Forty-five studies were eligible, and 15 met the inclusion criteria (4 acceptable and 11 low quality). This review was unable to determine the optimal content, mode, and timing for BCRL education across survivorship. Content included a brief overview of BCRL, early signs and symptoms, risk reduction practices, and a point of contact. Delivery was multi-modal, and knowledge acquisition was rarely assessed. Education was provided pre/post operatively and after BCRL developed.

Individualized BCRL education via a multi-modal approach, repeated at multiple time points, and assessment of survivors' knowledge acquisition is recommended. Consideration of the survivors' phase of treatment, content volume, and time required to complete the program is advised when developing the educational intervention.

Survivors of BC may need to advocate for BCRL education based on their individual risk and needs, request a point of contact for questions/follow up, and express their preferred style of learning.
