BACKGROUND: Limb lymphedema is a chronic disease with primary and secondary forms, with the latter occurring essentially after cancer treatment. In the present study, we retrospectively analyzed the cellulitis frequency and its associated risk factors for patients with primary or secondary limb lymphedema. METHODS: Information from all 1991 patients referred to a specialized lymphedema center from January to June 2018 was collected, including previous cellulitis episodes and the clinical and lymphedema characteristics. RESULTS: Of the 1846 patients whose information could be analyzed, 695 (37.6%) had experienced one or more cellulitis episodes, and 23.3% had had recurrent cellulitis. Cellulitis occurred in 39.5%, 30.5%, and 38.6% (P = .02) of the patients with secondary upper limb, secondary lower limb, and primary lower limb lymphedema, respectively. The corresponding duration of lymphedema was 106.5, 97, and 243.1 months. For secondary upper limb lymphedema, a long interval from lymphedema onset to the first consultation at our specialized center, younger age at lymphedema onset, and the use of radiotherapy were independently associated with cellulitis. However, axillary lymph node excision, the use of chemotherapy, and segmentation of the upper limb lymphedema were not associated with cellulitis. A longer interval from lymphedema onset to the first consultation and lymph node excision were associated with cellulitis in those with lower limb secondary lymphedema but higher body mass index and younger age at lymphedema onset were not. For primary lower limb lymphedema, male sex, greater body mass index, and younger age at lymphedema onset were associated with cellulitis. CONCLUSIONS: Different risk factors for cellulitis were identified for patients with lymphedema at risk. Awareness of those factors is important for physicians to recognize lymphedema promptly and refer patients to specialized centers to optimize treatment.
