Malignant melanoma: behavior with the nodes
Melanoma maligno: conducta con los ganglios
Resumen:
Lymph node dissections prevent lymphatic disseminations in melanomas, a fact which happens in 75 % of the cases. Prophylactic in continuity dissectionsshould be performed when the primary lies next to the regional lymph nades. Pro and con of prophylactic discontinuous dissections have been discussed for decadesand are summarized here. Prospective randomized studies of the I.R.C. for melanoma of the W.H.O. will give the answer to the problem. It seems at thepresent time that prophylactic lymphadenectomies are not justified when the primary is distant from the regional lymph nades. Therapeutic dissections should be performed unlessgeneral disseminatiin is present. In spite of not finding the primary lesion, a dissection should be done if lymph nades are positive.
Los vaciamientos ganglionares pueden evitar la diseminación linfática de los melanomas, lo cual ocurre en un 75 % de los casos. Deben realizarse vaciamientosprofilácticos en continuidad cuando el primario está adyacente a los ganglios regionales. Se resumen amplias discusiones sobre si deben o no realizarse vaciamientosprofilácticos en discontinuidad; la respuesta parece provenir de estudios prospectivos realizados al azar por la I.R.C. para melanoma de la O.M.S. Por elmomento no parecen estar justificados los vaciamientos profilácticos cuando el primario está distante de los ganglios. Los vaciamientos terapéuticos deben realizarse, salvoexistencia de diseminación. No obstante desconocer el primario, debe realizarse un vaciamiento si hay ganglios positivos.
