Oral tongue cancer is the most prevalent type of oral cavity cancer and
presents the worst prognosis. With the use of tumor, lymph node, distant
metastasis (TNM) staging system, only the tumor and lymph node size are
taken into account. However, several studies have considered the tumor
volume as a possible significant prognostic factor. Our study,
therefore, aimed to explore the prognostic implications of the relevant
nodal volume.
