SANCHEZ NAVARRO, Carolina et al. Magnetic resonance imaging for measuring tumour thickness in cancer of the tongue: correlation with the histopathological thickness in a sample of 15 patients. Rev Esp Cirug Oral y Maxilofac [online]. 2014, vol.36, n.1, pp.9-14. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.09.001.

Objective: The aim of this study was to analyse the correlation between the radiological thickness of cancer of the tongue in the pre-surgical study using magnetic resonance imaging and the histopathological thickness after the tumour resection. The tumour thickness is a predictive factor for the presence of neck metastases, as well as an independent prognostic factor of overall and disease free survival. The measuring of the thickness in the early stages is essential to determine the therapeutic response in these patients. Material and method: A retrospective analysis was performed on 15 patients subjected to surgery in the Maxillofacial Surgery Department HRU Carlos Haya in the period 2008-2010. Measurements of the radiological thickness were made using magnetic resonance in T1 sequences with contrast, and the correlation with histopathological thickness of the surgical piece was analysed. Results: Using the Pearson linear correlation test with both measurements, there was a correlation of 0.897, which indicated a positive and strong agreement. Conclusions: Magnetic resonance is useful in the pre-surgical evaluation in cancer of the tongue and has shown to be a reliable diagnostic test for measuring tumour thickness.
