- W2184170717 abstract "The present study tries to establish the utility of PET/CT in staging squamous cell carcinoma of oral cavity. Objective :To evaluate the effectiveness of PET/CT scanning in staging oral cancer in view of the exact delineation of the primary tumor and metastatic disease. Cross sectional study. Setting and design: Central government Tertiary care centre. 50 cases of oral carcinoma were included in the study. PET/CT imaging was done for all the patients. The PET/CT imaging was reported by a Nuclear Medicine expert and the CECT Imaging by a radiologist separately. Patients underwent wide local excision and lymph node dissection with or without reconstruction and post operative radiotherapy according to the stage. Each level of node resected were labeled and sent separately. The specimens were examined by histopathologist. The findings of CECT and PET/CT were expressed as sensitivity, specificity, positive predictive value and negative predictive value with post operative histopathology report as gold standard. Chi-Square Test, Statistical Package for Social Sciences (SPSS Inc., Chicago, IL, version 17.0 for Windows). Results: For assessing primary tumor, PET/CT had sensitivity, specificity,PPV and NPV of 72.6%, 89.03%, 80.23 % and 84.14 % respectively, CECT showed 62.38%, 70.21%, 61.81% and 70.71% respectively. For assessing nodal status, PET/CT had sensitivity, specificity, PPV and NPV of 79.54 %, 90.8 %, 53.8 % and 97.05 % respectively and CECT showed 61.1%, 84.7%, 35.06% and 94.21% respectively. The comparison was statistically significant with p value < 0.01. Assessment by PET/CT changed the treatment in only 5 patients (10%). PET/CT has higher sensitivity, specificity, PPV and NPV compared to CECT. It should be done in all cases with advanced oral cancer for better disease staging and treatment planning.
