Mair M, et al. - Superficial tumors with a favorable prognosis are erroneously grouped together with unfavorable, deeply infiltrating lesions in the same classification, as per TNM classification. Researchers conducted a retrospective study to compare tumor volume, thickness, and T classification as predictors of outcomes in surgically treated squamous cell carcinoma of the oral tongue. Findings suggested that tumor thickness could be taken as a proxy and dependable prognosticator of outcomes instead of calculating tumor volume, as confirmed by the agreement between the tumor thickness and volume.
