Résumé

PURPOSE: To noninvasively assess spectroscopic and metabolic profiles of healthy tongue tissue and in an exploratory objective in nontreated and treated patients with tongue squamous cell carcinoma (SCC). METHODS: Fourteen healthy subjects (HSs), one patient with nontreated tongue SCC (NT-SCC), and two patients with treated tongue SCC (T-SCC) underwent MRI and single-voxel proton magnetic resonance spectroscopy ((1)H-MRS) evaluations (3 and 1.5T). Multi-echo-times (1)H-MRS was performed at the medial superior part (MSP) and the anterior inferior part (AIP) of the tongue in HS, while (1)H-MRS voxel was placed at the most aggressive part of the tumor for patients with tongue SCC. (1)H-MRS data analysis yielded spectroscopic metabolite ratios quantified to total creatine. RESULTS: In HS, compared to MSP and AIP, (1)H-MRS spectra revealed higher levels of creatine, a more prominent and well-identified trimethylamine-choline (TMA-Cho) peak. However, larger prominent lipid peaks were better differentiated in the tongue MSP. Compared to HS, patients with NT-SCC exhibited very high levels of lipids and relatively higher values of TMA-Cho peak. Interestingly, patients with T-SCC showed almost nonproliferation activity. However, high lipids levels were measured, although they were relatively lower than lipids levels measured in patients with NT-SCC. CONCLUSION: The present study demonstrated the potential use of in-vivo (1)H-MRS to noninvasively assess spectroscopic and metabolic profiles of the healthy tongue tissue in a spatial location-dependent manner. Preliminary results revealed differences between HS and patients with tongue NT-SCC as well as tongue T-SCC, which should be confirmed with more patients. (1)H-MRS could be included, in the future, in the arsenal of tools for treatment response evaluation and noninvasive monitoring of patients with tongue SCC.
