Evaluation of Recurrence Outcomes After Treatment for Tongue and Mouth Floor Cancer at Cho Ray Hospital (2017–2022)
Main Article Content
Abstract
Objective: This study aimed to evaluate the characteristics of recurrence after treatment for tongue and mouth floor cancer and to identify factors associated with the recurrence rate.
Subjects and Methods: This was a retrospective descriptive study of 40 patients with squamous cell carcinoma of the tongue (n=37) and mouth floor (n=3) who received definitive treatment at Cho Ray Hospital between 2017 and 2022. Data collected included clinical, histological, and surgical information. Statistical analysis was performed using SPSS with chi-square, univariate, and multivariate logistic regression tests.
Results: In the tongue cancer group, the post-treatment recurrence rate was 35.1% (13/37). Recurrence primarily occurred in the cervical lymph nodes (46.2%) and in the tongue itself (30.8%). The time to recurrence was most often between 12 and 24 months after treatment (56.1%). No recurrence was recorded in the mouth floor cancer group. The only factor significantly associated with the risk of recurrence in the multivariate analysis was male gender (OR=9.41; 95% CI: 1.03–78.69; p=0.041).
Conclusion: The recurrence rate after tongue cancer treatment is relatively high, and male patients have a significantly higher risk of recurrence compared to females. Close post-treatment follow-up and a thorough evaluation of risk factors should be emphasized in clinical practice.
