OBJECTIVE: To evaluate the relationship of functional magnetic resonance imaging (MRI) parameters, including choline/creatine ratio (Cho/Cr) and apparent diffusion coefficient (ADC) with protein expression of 10 common tumor and prognostic markers in head and neck squamous cell carcinoma.
STUDY DESIGN: Cross-sectional study.
SETTING: University hospital.
SUBJECTS AND METHODS: The Cho/Cr and ADC obtained from 74 patients with head and neck squamous cell carcinoma were correlated with the expression level of the 10 protein markers as determined by immunohistochemistry.
RESULTS: Cho/Cr showed significant positive correlations with cyclooxygenase 2 in primary tumors (r = 0.714), and epidermal growth factor receptor in metastatic cervical lymph nodes (r = 0.522). ADC showed significant (r = −0.591) negative correlation with human epidermal growth factor receptor 2 in metastatic cervical lymph nodes.
CONCLUSION: There are relationships between protein and functional MRI markers. Future research in this direction may improve our understanding of the cancer micro-environment.
