Background and Objective: Oral cancer (OC) is one
of the head and neck cancers. Nowadays, the OC
trended to be increased, and there was no study about
the survival rate of OC patients in Buriram province.
Therefore, the objective of this study was to determine
the survival rate of OC after diagnosis in Buriram hospital,
Buriram province.
Methods: Data of patients with OC were retrieved
from the Buriram hospital-based cancer registry. OC
is an International Classification of Diseases for
Oncology, 3rd edition; C00 – C06. Patients with OC
who were histologically proved and admitted to the
Buriram Hospital (2014-2018) and followed up until
2019 of 339 cases. Survival rate were estimated by
the Kaplan-Meier method. We reported by median
survival time and 95% confidence interval. Comparison
group of survival rate were estimated by Log-rank test.
Result: Of 339 OC patients which follow-up time was
444 person-year, and died during the study were 261
cases, corresponding to mortality (Case-fatality) rate
of 59.0 per 100 person-year. (95% CI; 52.1 - 66.6). The
median survival of OC was 0.83 years (95% CI; 0.70 -
0.96). The overall survival experience of 1, 3 and 5 years were 43.9% (95% CI; 38.5 - 49.1), 25.0 % (95%
CI; 20.2 - 30.0), and 14.8 % (95% CI; 10.0 - 20.4),
respectively.
Conclusion: The 5-years survival rate of OC after
diagnosis at Buriram hospital was low. Therefore,
primary and secondary prevention are needed.
Screening program for early detection are required for
improving the survival rate. Including the factors
affecting to OC need to be focus.
