Sampling of sentinel lymph nodes: a simulation study

Anal Quant Cytol Histol. 2005 Aug;27(4):187-94.

Abstract

Objective: To analyze the effects of various slicing schemes on the detection of metastases in lymph nodes.

Study design: Use of an advanced computer simulation tool.

Results: Bisectioning along the longitudinal axis is an inadequate approach. Slicing ellipsoid lymph nodes along their longitudinal axis also results in a lower rate of detecting metastases since metastatic deposits have a predilection to localize subcapsularly.

Conclusion: Ellipsoid lymph nodes must be sliced perpendicular to the longest axis to increase the rate of detecting metastases.
