Malignancy
NO
This study aims to determine the association between the presence or absence of previous dental surgery to the tumour site prior to initial treatment and treatment course and prognosis in gingival squamous cell carcinoma.
Others
If the results of this study can clarify the extent to which dental surgical invasion affects the course of treatment (local neck and distant metastases) and prognosis, it will enable more appropriate adjuvant treatment to be selected and contribute to future oral surgery practice.
Confirmatory
Difference in survival with and without previous dental surgery (days from treatment start date to death with death as the event).
