SANCHEZ LOPEZ, J.D. et al. Tumor depth in squamous cell carcinoma of the tongue: Diagnostic repercussions. Rev Esp Cirug Oral y Maxilofac [online]. 2007, vol.29, n.1, pp.33-42. ISSN 2173-9161.

Objective. To determine the degree of concordance between clinical (cT) and histopathological (pT) values for tumor size in squamous cell carcinoma when introducing "tumor thickness" as a diagnostic marker. Materials and methods. 1) Design: A retrospective hospital study of 60 patients evaluated between January 1990 and July 1997 was carried out. 2) Variables: Patient dates, clinical and histopathological parameters. 3) Statistics: Correlation assessment by Kappa Index (p<0.05). Results. After the use of "tumor thickness" as a diagnostic indicator the following can be appreciated: • Correlation between cT and ppT: Reduction in the degree of concordance between cT and pT in relation to ppT (23.3 /12.5%). • Correlation between pT and ppT: 100% concordance between pT4 and ppT4. All tumors diagnosed as pT3 were changed to ppT4. Conclusion. When the parameter "tumor thickness" is used, a change can be appreciated in the early stage clinical and histopathological diagnosis, as tumor size (T) becomes advanced.
