Significados de negative sns en inglés

Patterns of metastasis can be identified and characterized in patients with tumor- negative SNs.

Histopathologic reexamination of SNs from the 69 patients identified 9 patients with false- negative SNs; 2 of these had same-basin recurrences.

Conclusions: The SN is a valuable prognostic indicator because only 8.9% of patients with tumor- negative SNs will develop recurrence.
