Objectives:
In this study, we investigate the relationship between the effects of tumor width and depth with the extracapsular nodal spread (ECS) in oral tumors.
Patients And Methods:
In this study we investigate retrospectively data of 107 patients (69 males, 38 females; mean age 45 years; range 25 to 79 years) with tongue tumors, who had undergone surgery in our clinic, between 1994 and 2004. Twenty-one of them had ECS. The effects of tumor width and depth on various parameters such as nodal metastases, survival, grade and ECS are investigated.
Results:
It was found that tumor width and depth were the most important factors that affect ECS and logistic regression analysis point out tumor width influence more than tumor depth. Receiver operating characteristic (ROC) curve analysis shows us when tumor width exceeds 3.7 cm or tumor depth exceeds 2.4 cm, rate of ECS reaches the maximum sensitivity and specificity.
Conclusion:
Tumor width and depth has affects on survival and prognosis but also they have significant relation with ECS.
