Abstract: category in major cancers. Literature is scarce concerning the prognostic ability of LODDS in oral squamous cell carcinoma (OSCC) patients. Aims: The present study was aimed toevaluate the importance of LODDS in predicting locoregional recurrence and overall survival (OS) in patients with OSCC compared to LNR. Settings and Design: The retrospectivestudy was carried out on 194 patients with OSCC cases treated by surgery ± adjuvant therapy from 2008 to 2014 at our institution. Subjects and Methods: Demographical andclinicopathological details of study cases were recorded. LNR and LODDS were calculated and expressed as a percentage and mean ± standard deviation. Statistical Analysis Used: The OS analysis was done by the Kaplan–Meier curve followed by log-rank (mantel-cox) test. Univariate and multivariate survival analysis was done to analyze the prognostic ability ofLNR% and LODDS after adjusting the clinicopathological parameters by the Cox proportional hazards model. Results: Patients with cut off values of LODDS >-1.2 and LNR% >4 hadsignificantly lower mean OS ( P = 0.001). Multivariate analysis indicated that only mean LODDS >-1.2 was significantly associated with poor OS. Although there was a correlation withlocoregional recurrence, LODDS and LNR failed to be the independent predictors of locoregional recurrence. Conclusions: LODDS was an independent reliable prognostic indicator forpatients with OSCCs than conventional staging systems and LNR.
