Analysis of Treatment Results for Oral Tongue Cancer

Abstract

Significant improvement in DSS was seen in patients with clear margins, early stage grouping and clinical (pretreatment) tumor stage, and negative nodes. Significant decrease in DSS was seen in patients with close or involved margins, advanced stage grouping and clinical (pretreatment) tumor staging, positive clinical (pretreatment) node staging, and tumor recurrence. Obtaining clear margins of resection is crucial because it significantly affects survival. A minimum of 5 years of close monitoring is recommended because of the high incidence of second primary cancers.
