Aim: This study aims to assess whether preoperative platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) can predict occult metastasis in oral squamous cell carcinoma (OSCC). Materials and Methods: Thirty-five OSCC cases were analyzed for clinicopathological and hematological data. Cases without metastasis (pN0) were checked for micrometastasis immunohistochemically using Desmoglein 3 (DSG3) and Cytokeratin (CK). Mean PLR and NLR were compared and analyzed between the study groups. Results: Metastatic deposits were detected in 9 out of 26 pN0 cases (34.6%) accounting for 11 out of 62 (17%) lymph nodes subjected to immunohistochemistry. The mean PLR was higher in OSCC cases with or without occult metastasis in comparison to controls (P < 0.001). No significant difference was found in the mean PLR and NLR between OSCC cases with and without occult metastasis. Furthermore, we found DSG3+ sinus histiocytes within the lymph nodes in majority of cases which is least reported in literature. Conclusion: A significant percentage of cases showed occult metastasis in this study which led to upstaging of tumor. Although PLR was elevated in OSCC cases, it did not have a positive correlation with the presence of occult metastasis but was able to successfully distinguish OSCC patients from healthy individuals.
