Conclusion:

In terms of patient and disease-related characteristics, a significant difference between the younger and older group of patients was observed for gender, smokeless tobacco consumption, tobacco smoking, alcohol consumption, and the presence of co-morbidities. Higher tumour grade, involved tumour margins, presence of PNI, higher pN stage, and ECE were associated with an overall worse LRC, whereas, tobacco smoking, higher tumour grade, involved tumour margins, PNI, higher pN stage, and ECE were significant for poorer OS. Current study suggests no difference in LRC or OS in younger vs older patients with OTSCC at the end of 3 or 5 years. It is suggested that age is not an independent predictor of outcome for these patients. There is no rationale for the use of a different management approach or treatment intensification for the younger patients.

UICC8, but not 7, can identify high risk of locoregional failure as good as our multi-endpoint model
