Can Radiological Tumour Thickness Predict Pathological Prognostic Factors in Clinicoradiologically Node-Negative Oral Squamous Carcinoma? A Prospective Study.

Abstract

This research investigates potential connections between radiological tumour thickness determined by CT scans and various pathological prognostic factors. These factors include pathological tumour thickness (pTT), pathological depth of invasion (DOI), and positive cervical nodal metastasis. This analysis focuses on cases of clinicoradiologically node-negative squamous cell carcinoma of the buccal mucosa. Sixty-one previously untreated clinicoradiologically node-negative squamous cell carcinoma of buccal mucosa were included in the study. The radiological tumour thickness in the preoperative CT scans is correlated with other prognostic factors like pathological tumour thickness, DOI and presence or absence of neck node. Sixty-one patients were included in the study with a median age of 54 years (Range 27-84). Forty-two patients (68.9%) were male, and 19 were females (31.1%). There was no statistically significant difference in mean values of rTT among patients with positive or negative post-operative nodal metastases. However, a significant correlation could be established with rTT to other potential prognostic factors. Tumor thickness in preoperative CT scans can be used to predict post-operative prognostic factors in oral squamous cell carcinoma.
