Aspectos técnicos de interés en la localización de drenajes linfáticos en la biopsia del ganglio centinela del cáncer de mama

In breast cancer sentinel lymph node biopsy, the number of identified nodes is not influenced by the use of a mixed technique or radiotracer alone. However, the number of identified nodes is higher with the periareolar route than with the intraperitumoral route. Intra-peritumoral injection of the tracer shows a higher frequency of internal mammary chain drainage than periareolar injection, although this difference was not statistically significant.
