Surgery, Limb Edema and Health-related Quality of Life: A Prospective Follow-up Study on Patients With Cutaneous Malignant Melanoma

Abstract

Background/Aim: The latest developments in oncological therapies for malignant melanoma, and the discovery that complete lymph node dissection offers no survival benefit, are changing the landscape of melanoma surgery. There is a need for more information on health-related quality of life (HRQoL) consequences of melanoma surgery. Patients and Methods: This longitudinal cohort study was carried out from 2004 to 2009 in the Helsinki and Uusimaa Hospital District and patients were followed-up at 6, 12 and 24 months. The patients were asked to fill in the generic 15D questionnaire and the cancer-specific European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-30). In addition, they were asked selected questions from the EORTC Item Library regarding upper and lower limb edema. Results: A total of 169 (64.5%) patients with local or locally advanced melanoma referred for surgical treatment responded, of whom 161 were included in the final analysis. For the whole patient group, distress, depression and emotional function improved over time. Worse HRQoL in some of the dimensions were associated with female sex, skin transplant versus direct wound closure and complications 30 days or more after surgery, but none was associated with worse overall HRQoL. Postoperative complications, type of wound closure or lymph node surgery had no effect on overall HRQoL. Patient-reported limb edema was associated with worse overall HRQoL at baseline and during follow-up by both instruments. Patients reporting limb edema reported worse mobility and more pain throughout the study. Conclusion: Patient-reported limb edema, regardless of the cause, seems to be an important predictor of worse HRQoL among patients with melanoma.
