To investigate the prevalence and risk factors for adhesive capsulitis in postoperative breast cancer patients up to 5 years after surgery who were attending an outpatient community cancer rehabilitation program, and to determine whether any significant relationship exists between arm lymphedema and adhesive capsulitis. Cross-sectional observational study. National cancer rehabilitation center. Asian women (N=135) who underwent breast surgery and were referred for an outpatient community cancer rehabilitation program. Not applicable. Presence of adhesive capsulitis, lymphedema. The prevalence of adhesive capsulitis and lymphedema in this population was 22.2% and 33.3%, respectively. A history of mastectomy (odds ratio [OR], 3.93; 95% confidence interval [CI], 1.23-12.63; P=.021), mastectomy with reconstruction (OR, 2.72; 95% CI, 1.27-30.54; P=.024), and lymphedema (OR, 7.92; 95% CI, 2.73-22.95; P<.001) were found to be significantly associated with adhesive capsulitis on multivariate analysis. Adhesive capsulitis and lymphedema are common in breast cancer survivors. The design of cancer rehabilitation programs for breast cancer survivors should include surveillance and management of adhesive capsulitis, especially in the presence of lymphedema.
