Aim: To ascertain the prognostic value of cervical nodal necrosis (CNN) observed in patients of tongue squamous cell carcinoma with magnetic resonance imaging. Materials and methods: In this retrospective observational study, records of 144 patients diagnosed with newly diagnosed SCC of tongue were considered. Preoperative MRI study, demographic and clinical data were reviewed. Based on MRI reports, patients were categorised into: with or without the presence of cervical node necrosis (CNN or non CNN). Subsequent treatments, histopathological reports and follow up data were studied to determine key prognostic elements, overall survival and disease free survival by statistical analysis. Results: The incidence of CNN was 55.55% in the study sample. CNN category, depth of invasion, N stage and extra nodal extension were significant negative prognostic factors for overall and disease free survival. Conclusion: Based on our results, pre operative MRI based presence of cervical node necrosis in tongue squamous cell carcinoma is an independent prognostic indicator for poor overall and disease free survival. Long term prospective studies with larger cohorts could be undertaken to establish its role as an important biomarker for precision treatments.
Key words: Cervical node necrosis / MRI / squamous cell carcinoma / tongue / prognostic factor
