Objectives
Narrative objectives1
This study aims to examine cases of oral cancer with other risk features and identify cases that are at high risk of recurrence and metastasis and should therefore receive postoperative adjuvant therapy equivalent to that given to high-risk cases, based on recurrence rates and survival rates. Clarifying this will help to determine the appropriate use of postoperative adjuvant therapy and contribute to the future treatment of oral cancer.
