Tumor Thickness of Oral Lesions with and without Metastasis in Neck

Abstract

Objective: To determine the association of thickness of tumor of oral lesions with and without metastasis in neck based on computerized tomography (CT) scan. Methods: A retrospective study was conducted among patients having age >18 years of either gender diagnosed with oral squamous cell carcinoma (SCC). Moreover, patients with buccal mucosa and tongue malignant tumor were also included. CT scan was performed on all patients and tumor thickness in anteroposterior, transverse, and craniocaudal positions were measured. Results: A total of 119 patients were included. The mean age of the patients was 46.97 ±11.79 years. Male preponderance was found to be higher 102 (85.7%) than that of females 17 (14.3%). The mean anterioposterior thickness level was significantly higher in right side of oral cavity as compared to left side (4.39 ±2.12 vs 3.52 ±1.56, p-value 0.015). Moreover, mean transverse dimension was found significantly higher among patients in whom post tongue was involved as compared to those among which post tongue was not involved (5.05 ±1.56 vs 2.64 ±1.78, p-value 0.009). Metastasis was significantly higher among patients with right side of oral tumor as compared to those with left side of oral tumor (p-value 0.043). Conclusion: Metastasis of anterioposterior thickness level was significantly higher among patients with right side of SCC while transverse dimension was found significantly higher among patients in whom post tongue was involved.
