Purpose: Axillary web syndrome (AWS) presents as a common postsurgical complication in individuals with breast cancer. Breast cancer-related lymphedema (BCRL) contributes to the shoulder and arm morbidity common in breast cancer survivors and often associated to cancer treatment. A paucity of literature exists evaluating the risk factors for developing AWS and the association between AWS and BCRL. The purposes of this study were (1) to identify risk factors for AWS in individuals with breast cancer, (2) to examine the association between BCRL and AWS, and (3) to determine if AWS increases the risk for developing BCRL.
Methods: A retrospective study of 354 women who underwent breast cancer treatment and received physical therapy was included.
Results: Axillary web syndrome developed in a third of women and predominately occurred in the first 8 postoperative weeks. The odds of AWS development were 73% greater for participants over the age of 60 (OR = 1.73, CI 95% 1.05-2.84). Women with AWS had 44% greater risk to develop lymphedema during the first postoperative year (RR = 1.44, CI 95% 1.12-1.84, p = 0.002). If AWS developed within the first postoperative month, women were almost 3 times more likely to develop lymphedema within the first 3 postoperative months compared with other women with AWS (RR = 2.75, CI 95% 1.199-6.310, p = 0.007).
Conclusions: Our findings suggest that 30% of breast cancer survivors will have AWS during the first year of survivorship. As institutions prioritize screening efforts, early postoperative prospective surveillance is needed for women over 60 due to high risk for AWS development and any women with AWS for increased risk of lymphedema development based on our findings.
