ABSTRACT
OBJECTIVES:
Although T stage is an important prognostic tool for oral tongue cancer, it fails to define the depth of invasion and true three-dimensional volume of primary tumors. The purpose of this paper is to determine the relations between tumor volume and lymph node metastasis and survival in early oral tongue cancer.METHODS:
Forty-seven patients with T1-2 tongue cancer were included. Tumor volumes were measured by the computerized segmentation of T2-weighted magnetic resonance imaging.RESULTS:
The overall average tumor volume was 27.7 cm3 (range, 1.4 to 60.1 cm3). A significant positive correlation was found between tumor volume and pathological T stage, depth of invasion, and cervical lymph node metastasis (P or =20 cm3) and the 5-year disease-specific survival (P=0.046).CONCLUSION:
Tumor volume larger than 20 cm3 was associated with greater risk cervical lymph node metastasis and poor 5-year disease-specific survival rate in early oral tongue cancer patients.
