Efficacy of Kinesio Taping Versus Compression Therapy on Breast Lymphedema Induced by Radiotherapy After Breast-Conserving Surgery

This is a single‐center, three‐arm, parallel‐group randomized controlled trial conductedat the Department of Breast Surgery, Tangshan People's Hospital (RMYY). A total of 99female patients with unilateral breast cancer who have undergone breast‐conservingsurgery, completed radiotherapy for at least 2 months, and developed radiotherapy‐relatedbreast lymphedema will be enrolled. Participants will be randomly assigned in a 1:1:1ratio to one of three groups: (1) routine care (control), (2) routine care plus KinesioTaping, or (3) routine care plus compression therapy. The intervention period lasts 6weeks.Outcome measures include:Breast skin thickness measured by ultrasound at four quadrants (upper outer, upper inner,lower outer, lower inner), each measured at 35‐40 mm from the nipple, with 3 imagesaveraged per location; Lymphedema‐related symptoms (pain, swelling, heaviness, tightness)assessed by Visual Analog Scale (VAS), scored 0‐10; Breast transverse and verticaldiameters measured by cross‐measurement method using a non‐elastic tape measure; Qualityof life assessed by the Functional Assessment of Cancer Therapy‐Breast (FACT‐B) Chineseversion (36 items, 5‐point Likert scale, total score 0‐144); Self‐efficacy assessed bythe Breast Cancer Survivors Self‐Efficacy Scale (BCSES) Chinese version (11 items,5‐point Likert scale, total score 11‐55); Anxiety and depression assessed by the HospitalAnxiety and Depression Scale (HADS) Chinese version (14 items, 7 for anxiety and 7 fordepression).Assessments will be conducted at baseline (T0), immediately post‐intervention at 6 weeks(T1), and at 3 months (T2) and 6 months (T3) post‐intervention.Sample size is 33 participants per group (total 99, including 20% attrition allowance).Randomization will be performed using block randomization with a 1:1:1 allocation ratio.Statistical analysis will follow the intention‐to‐treat principle. Adverse events will bemonitored throughout the study and recorded via follow‐up logs and WeChat (a Chinesemulti‐purpose messaging, social media, and mobile payment app developed by Tencent)platform.The study protocol has been approved by the Medical Ethics Committee of Tangshan People'sHospital (LLKS) (Approval No. RMYY‐LLKS‐2025304), and all participants will providewritten informed consent before enrollment.
