Laparoscopic sentinel lymph node biopsy for XXXX : the relevance of locations outside the extended dissection area.

@entity1 @entity263 @entity5
Objective. To assess the relevance of sentinel lymph nodes (SNs) outside the extended pelvic lymph node dissection area (e-PLND). @entity1 and Methods. Evaluation of our laparoscopic SN procedures for @entity263 @entity1 of intermediate prognosis. Retrospective data collection on the exact location of the excised SNs and the pathology results were analyzed. Results and Limitations. Of the 121 @entity1 , 49 had positive lymph nodes. 37 @entity1 (31%) had SNs outside the e-PLND template. Five of these nodes were @entity5 bearing but only twice exclusively so. Of the 14 @entity1 considered for salvage treatment, 6 were node positive. 7 of these 14 @entity1 (50%) had SNs outside the extended dissection area, yet none of these nodes were @entity5 positive. Limitations are those of a retrospective study. Conclusions. Laparoscopic SN biopsy may show SNs outside the e-PLND template in 31% of the @entity1 . However, nodes that are exclusively positive in one of these areas are rare. For the dichotomy positive or negative nodes, the locations outside the e-PLND area are not often relevant. Nevertheless, when all positive nodes are to be treated by resection or radiotherapy, these locations are relevant. When considering salvage treatment for @entity263 , the method is feasible.
