Risk factors for lymphedema after breast surgery: A prospective cohort study in the era of sentinel lymph node biopsy.

INTRODUCTION: The Objective was to investigate the incidence of lymphedema after breast cancer treatment and to analyze the risk factors involved in a tertiary level hospital. METHODS: Prospective longitudinal observational study over 3 years post-breast surgery. 232 patients undergoing surgery for breast cancer at our institution between September 2013 and February 2018. Sentinel lymph node biopsy (SLNB) or axillary lymphadenectomy (ALND) were mandatory in this cohort. In total, 201 patients met the inclusion criteria and had a median follow-up of 31 months (range, 1-54 months). Lymphedema was diagnosed by circumferential measurements and truncated cone calculations. Patients and tumor characteristics, shoulder range of motion limitation and local and systemic therapies were analyzed as possible risk factors for lymphedema. RESULTS: Most cases of lymphedema appeared in the first 2 years. 13.9% of patients developed lymphedema: 31% after ALND and 4.6% after SLNB (p < 0.01), and 46.7% after mastectomy and 11.3% after breast-conserving surgery (p < 0.01). The lymphedema rate increased when axillary radiotherapy (RT) was added to radical surgery: 4.3% for SLNB alone, 6.7% for SLNB + RT, 17.6% for ALND alone, and 35.2% for ALND + RT (p < 0.01). In the multivariate analysis, the only risk factors associated with the development of lymphedema were ALND and mastectomy, which had hazard ratios (95% confidence intervals) of 7.28 (2.92-18.16) and 3.9 (1.60-9.49) respectively. CONCLUSIONS: The main risk factors for lymphedema were the more radical surgeries (ALND and mastectomy). The risk associated with these procedures appeared to be worsened by the addition of axillary radiotherapy. A follow-up protocol in patients with ALND lasting at least two years, in which special attention is paid to these risk factors, is necessary to guarantee a comprehensive control of lymphedema that provides early detection and treatment.

[Facial and labial lymphedema after oncological treatment. A propos of clinical case]. / Linfedema facial y labial secundario a tratamiento oncológico. A propósito de un caso clínico.

Facial lymphedema secondary to treatment by a neoplastic process is a rare and disabling pathology, causing functional and aesthetic alterations. A case report of facial and labial lymphedema describing the functional repercussion and aesthetic defect. We present a 61-years-old female patient suffered a tongue neoplasia and bilateral cervical lymphadenectomy in 2015. After several treatments, including diverse surgical interventions and adjuvant radiotherapy, developed facial and labial lymphedema. The patient was sent to our Rehabilitation Department complaining about swelling of the face and lips, dysphagia, sialorrhea, xerostomia, dysarthria and decubitus in lower lip by labia protusion. Due to the functional repercussion that it caused in the patient, rehabilitating physical treatment was planned with manual lymph drainage, facial silicone orthosis and lymphatic taping. The patient improved both subjectively as well as objectively in terms of hardness, volume and slight improvement of lip lymphedema.
