[Sentinel lymph node-multicentric and multifocal tumors: a valid technique?]. / Ganglion sentinelle et tumeurs multifocales-multicentriques : une technique valide ?

Sentinel node biopsy without complementary axillary lymph node dissection was validated for T1-2 N0 unifocal breast cancer without previous treatment since several years. In the situation of multifocal multicentric breast tumors, this procedure was considered as a contraindication. The aim of this work was to analyse literature results to determine if sentinel lymph node biopsy can be considered as a valid option without complementary axillary lymph node dissection for negative sentinel lymph node.

[Regional treatment for axillary lymph node micrometastases of breast cancer]. / Traitement régional des cancers du sein en cas de micrométastase ganglionnaire axillaire.

In patients with breast cancer, axillary lymph node micrometastasis detection has been more frequent with a better definition since the introduction of the sentinel node procedure. In this review, we focus on pN1mi micrometastasis and review the literature in order to determine factors involved in making the decision of a regional treatment.
