Análisis del valor de la biopsia del ganglio centinela en el melanoma cutáneo.

The incidence of cutaneous melanoma has increased in our country recently. We report our experience during 20 years in 1023 cases, comparing the survival between 2 groups of patients: group A treated before 2000, and group B treated after 2000, based on the different treatment after the introduction of sentinel lymph node biopsy in 2000. There are no differences in survival rates between both groups in spite of being more conservative. Moreover, 75% of the lymphadenectomy could be evitated. [ABSTRACT FROM AUTHOR]
