Head and Neck Squamous Cell Carcinoma
Conditions
Brief summary
Head and neck squamous cell carcinoma are frequent. The chemoradiotherapy protocols are part of the reference treatment of locally advanced stage tumors. Diffusion-weighted MRI (DW-MRI) is a non radiating imaging, not requiring injection of gadolinium, giving informations on tumor activity, based on the brownian motion of water molecules. The differences in motion are expressed by the apparent diffusion coefficient (ADC). The ADC variations reflect changes in water molecules motion and redistribution between the intra- and extracellular compartments. Several studies have shown that malignant lesions have an ADC coefficient lowered as compared to benign lesions.
Detailed description
study the diagnostic performance of diffusion MRI performed in early post treatment, notably changes in the ADC factor, in the onset of tumor recurrence or progression in patients showing no residual tumor at the end a treatment by chemoradiotherapy for squamous cell carcinoma of head and neck seat. compare the characteristics of diffusion MRI, such as ADC coefficient, between patients with residual tumor and patients with no residual tumor after chemoradiotherapy for squamous cell carcinoma of head and neck location.
Interventions
Two diffusion-weighted MRI will be performed (one 8 days before chemoradiotherapy treatment and one 3 months after the end of chemoradiotherapy treatment).
