Effects of a complex rehabilitation program on edema status, physical function, and quality of life in lower-limb lymphedema after gynecological cancer surgery

The purpose of this study was to investigate the effects of a complex rehabilitation (CR) program and complex decongestive therapy (CDT) on edema status, physical function, and quality of life in patients with unilateral lower-limb lymphedema after gynecologic cancer surgery.In this randomized pilot study, 40 patients with secondary unilateral lymphedema, after gynecologic surgery for cervical, endometrial, or ovarian cancer, that had been diagnosed based on clinical assessment and 10% volume differences between the legs were randomly assigned to the CDT (n=20) and CDT combined with CR (CRCDT; n=20) groups. CR comprised stretching, strengthening, and aerobic exercises performed for 40min, five times a week for 4weeks. Intensive CDT was administered by a physical therapist during weeks 0-2 and by the patients themselves during weeks 2-4. Limb volume, bioimpedance, muscular strength, EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30) score, 30-s chair stand test, muscular strength, and GCLQ-K (Korean version of the Gynecological Cancer Lymphedema Questionnaire) score were assessed at baseline and after 4weeks of treatment.The edema status, fatigue, pain, and GCLQ-K scores were significantly improved in both groups after the 4-week intervention (P<0.05). Physical function and fatigue in EORTC QLQ-C30 and the 30-s chair stand test and quadriceps muscle strength were significantly improved in the CRCDT group compared with the CDT group (P<0.05).CR improves physical function, fatigue, and muscular strength without increasing edema status in patients with unilateral lower-limb lymphedema after gynecologic cancer surgery.
