Megjegyzések:Objectives: To determine the feasibility of pre-treatment primary tumor FDG-PET and DWI-MR imaging param-eters in predicting HPV status and the second aim was to assess the feasibility of those imaging parameters to predict response to therapy. Material and Methods: We retrospectively analyzed primary tumors in 33 patients with proven OPSCC. PET/MRI was performed before and 6 months after chemo-radiotherapy for assessing treatment response. PET Stan-dardized uptake value (SUVmax), total lesion glycolysis (TLG), metabolic tumor volume (MTV), and apparent diffusion coefficient (ADC) from pre-treatment measurements were assessed and compared to the clinicopath-ological characteristics (T stages, N stages, tumor grades, HPV and post-treatment follow up). HPV was corre-lated to the clinicopathological characteristics. Results: ADCmean was significantly lower in patients with HPV+ve than HPV-ev, (P =0.001), cut off value of (800 ?0.44*10-3mm2/s) with 76.9% sensitivity, and 72.2% specificity is able to differentiate between the two groups. No significant differences were found between FDG parameters (SUVmax, TLG, and MTV), and HPV status, (P =0.873, P =0.958, and P =0.817), respectively. Comparison between CR and NCR groups; ADCmean, TLG, and MTV were predictive parameters of treatment response, (P =0.017, P =0.013, and P =0.014), respectively. HPV+ve group shows a higher probability of lymph nodes involvement, (P =0.006) Conclusion: Our study found that pretreatment ADC of the primary tumor can predict HPV status and treatment response. On the other hand, metabolic PET parameters (TLG, and MTV) were able to predict primary tumor response to therapy.
