METHODS: A total of 989 OSCC treated with neck dissection were selected. All the relevant data were recorded from biopsy request forms. The patients were divided into seven groups, and there were nine different oral sites.
RESULTS: The male-to-female ratio of the sample was 4:1. Most of the patients were aged between 30 and 60 years. Of the 989 patients, approximately 40% patients had metastasis. Age <30 years showed a higher probability of metastasis compared to higher age groups, but it was not statistically significant. Palate cancers had more than 14 times higher chance of metastasis, followed by maxilla (4.6 times) and tongue (2.8 times).
CONCLUSION: The present study provides important information on the metastatic potential of OSCC in different oral sites, and identifies high-risk age groups for metastasis. This will be helpful in planning neck treatment for OSCC.
