Avaliação do linfonodo sentinela no tratamento do melanoma cutâneo: sistematização de técnica com linfocintigrafia e azul patente / Sentinel lymph node evaluation in the treatment of cutaneous melanoma: systematization of a technique using lymphoscintigraphy and patent blue
A total of 12 cases were studied between March 2009 and March 2012. The treatment protocol followed criteria established by the Brazilian Group of Melanoma. Patients were evaluated for age, sex, thickness of the primary lesion, localization of drainage site ofthe sentinellymph node,and presence ofmetastases.
Results:
The majority of patients were male and the mean age was 49.7 years. The types of thickness most frequently found were Breslow thickness 0- 1 mm and Clark levei lI. Ali of the dissected lymph nodes were stained with patent blue. Histological and immunohistochemical analysis of the lymph nodes were negative for metastases.
