Regional non-nodal metastases of cutaneous melanoma.
The authors studied the prognosis of patients with so called local recurrences, satellites and in-transit metastases from cutaneous melanoma on the basis of 291 patients. These are the 19.3% of the 1503 patients with stage I and II melanoma originally submitted to surgical treatment at the National Cancer Institute of Milano (Italy). The majority of patients were males (M/F = 0.7): 102 had local recurrence, 99 in-transit metastases, 24 satellites and 66 both local and in-transit metastases. Regional non-nodal metastases were not related with the site of origin, and inadequate treatment of primary. These metastases were more frequently observed in patients who were submitted to regional node dissection no matter whether in discontinuity or in continuity with primary tumor. The frequency of regional non-nodal metastases was found to increase with increasing thickness of primary melanoma or, in stage II patients, with the number of involved nodes. Local and in-transit metastases were related with prognostic criteria in the same way. The overall survival was very close between in-transit and local metastases. Similar survival rates were observed comparing regional non-nodes and disseminated cutaneous and subcutaneous metastases. The authors conclude that the distinction between local recurrences, satellites and in-transit metastases is artificial and that these metastatic events are not prognostically dissimilar from metastases in distant skin areas.
