Lymphatic mapping for melanomas of the upper extremity.
Over a period of 4 years, 127 consecutive patients with upper extremity melanomas were identified from a prospectively accrued database. A protocol consisting of preoperative lymphoscintigraphy and intraoperative lymphatic mapping and with a vital blue dye and radiocolloid was used; the protocol had a 98% success rate of identifying the sentinel lymph node (SLN). Preoperative lymphoscintigraphy identified unpredictable cutaneous lymphatic flow in 15 (12%) of the patients. These discordant areas would not have been included in classic regional node dissection and possible sites of metastatic disease would not have been identified. Metastatic disease was identified within the SLNs in 12 (9%) of the patients. Of the 12 patients with a positive SLN, 2 (17%) were found on complete node dissection to have metastatic disease in higher nodes in the regional basin. The SLN was the only site of disease in 10 of these 12 patients with documented metastases in the regional basin. Patients with a negative SLN biopsy can be spared the morbidity and expense of a complete lymph node dissection.
