Prevalence and associations of axillary web syndrome in Asian women after breast cancer surgery undergoing a community-based cancer rehabilitation program

Abstract

Background Patients who have breast cancer surgery are at risk of axillary web syndrome (AWS), an under-recognized postsurgical complication which can result in shoulder morbidity and functional impairment. Emerging studies have indicated that AWS may persist beyond the first few months after surgery, although few studies have assessed the prevalence and association of AWS beyond a year after diagnosis. Therefore, the aim of this study was to investigate the prevalence and associations for AWS in post-operative breast cancer patients up to 3\u2009years after surgery. Methods This cross sectional observational study was conducted at a community-based cancer rehabilitation center. Patients were evaluated for the presence of AWS via physical examination. Disease-related data was obtained from clinical review and medical records. Descriptive statistics were utilized to illustrate patient demographics and clinical characteristics. Logistic regression analyses were used to determine associations of AWS. Results There were 111 Asian women who were recruited, who had undergone breast surgery and were referred to a national outpatient rehabilitation center. The prevalence of AWS in this population was 28.9%. In the multivariate regression model, significant factors were age\u2009<\u200950\u2009years (OR\u2009=\u20093.51; 95% CI\u2009=\u20091.12–11.0; p \u2009=\u20090.031) and ALND (OR\u2009=\u20096.54; 95% CI\u2009=\u20091.36–31.3; p \u2009=\u20090.019). There was reduced shoulder flexion ROM ( p \u2009<\u20090.001) in patients with AWS compared to patients without AWS. Conclusions A high prevalence of AWS was reported in breast cancer survivors even at 3\u2009years after breast surgery. Our findings highlight the need to identify breast cancer survivors with AWS even in the survivorship phase, and develop strategies to raise awareness and minimize functional impairment in these patients.
