Research Project:

Name of the project

 Sentinel Node Biopsy for Oral Squamous Cell Carcinoma


Description of the project (including, relation to the main work of the laboratory, procedures and methods used in the project):

  All sentinel nodes were excised selectively, and extensive histopathological work-up was performed. In every sentinel nodes -positive patient, completion radical or functional neck dissection was performed. Overall survival , disease-specific survival , disease-free survival , and regional control rate were calculated.

Aim of the project:

     The objective of the study was to evaluate the validity of sentinel node biopsy in  oral cancer patients focusing on the accuracy of intraoperative diagnoses of SN status, recurrences in follow-up and impact on patient survival.
