Elastography in the assessment of sentinel lymph nodes prior to dissection

These encouraging results show a correlation between the metastatic risk of lymph nodes and their increased mean stiffness. Elasticity variables and potential thresholds that seem to predict the metastatic status of axillary lymph nodes were identified. If confirmed by further larger studies, these results could be useful in clinical practice for the identification of lymph nodes at high metastatic risk that could benefit from a intra-operative analysis to reduce the number of secondary surgical procedures.
