RESUMEN
ResumenEl carcinoma de mama representó el tumor en mujeres más frecuente en Costa Rica para el año 2013. La disección axilar en el cáncer de mama es una de las causas de mayor comorbilidad en las pacientes. La realización de un ganglio centinela para determinar si es necesario la disección axilar, ha resultado de gran ayuda, reduciendo las comorbilidades en las pacientes con cáncer de mama. La experiencia del cirujano en la realización de procedimiento y del patólogo, han reducido los falsos negativos en los ganglios centinelas por congelación hasta en un 4.5%.En este estudio se analizaron los ganglios centinelas por congelación que contaban con biopsia definitiva y se determinó que los falsos negativos para nuestro hospital eran del 1.2%, además en estos casos, se determinó la media de tipo histológico, el grado histológico y el tamaño del cáncer de mama. En conclusión, se determinó que una de las casusas principales asociadas a los falsos negativos es la presencia de tejido adiposo en el ganglio centinela.
ABSTRACT
AbstractBreast carcinoma represented de most frequent tumor in Costa Rica during 2013. The axillary dissection in pacients with breast cancer is one of the causes of the most frecuent comorbidity. Studying sentinel ganglion to decide if it is necesary to make an axillary dissection has become very useful in reducing comorbidity in pacients with breast cancer. The surgeon´s and de pathologist´s work experience with this procedure has reduced false positive results in the sentinel ganglion´s biopsies by frezzing method in 4,5%. During the current report the sentinel ganglions by freezing method that had a definite biopsy were studied and we arrived to the conclusion that for our hospital falsepositives were less than 1,2%. As well in this cases it was determined the histologic type, the histologic grade and the size of the breast cancer. In conclusion it was determined that one of the most frecuent causes associated with false positives is the presence of adipose tissue in the sentinel ganglion.
