The Comparative Frequency of Breast Cancer-Related Lymphedema Determined by Perometer and Circumferential Measurements: Relationship with Functional Status and Quality of Life.

Background: The aim of this study was to comparatively determine the frequency of breast cancer-related lymphedema (BCRL) by using prospective monitoring with perometer and circumferential measurements in a group of patients who underwent breast cancer surgery. We also aimed to evaluate the relationship between volume changes and functional status and quality of life (QoL) in patients with breast cancer-related subclinical lymphedema. Materials and Methods: Patients who had unilateral breast cancer surgery for breast were assessed with circumferential and perometer, respectively, for volumes at baseline, 3rd-month, 6th-month, 9th-month, and 12th-month by the same physiotherapist. Every patient was informed about lymphedema symptoms and prevention. The demographic and clinical properties were recorded. Functional status and QoL were evaluated by Q-DASH and the Lymphedema Quality of Life Questionnaire-Arm questionnaires. Results: A total of 101 female patients with a mean age of 49.02 + 10.59 years completed the 12-month follow-up. Most of the patients were overweight, had an axillary dissection in addition to breast surgery, and received radiotherapy. The frequency of subclinical and clinical BCRL at the end of 12 months was determined by 34.7% and 23.8% with circumferential measures and perometer, respectively. QoL and functional scores did not differ between patients with and without subclinical lymphedema. Conclusion: After the first 12 months after surgery, the frequency of BCRL assessed by circumferential measurements was higher than the frequency assessed by perometer. Periodic monitoring of women with breast cancer for the presence of BCRL, preferably by the same person together with patient education is suggested in order to allow early detection and timely intervention for BCRL.
