Abstract
The surgical management of the clinically node negative neck in T1–T2 early oral tongue squamous cell carcinoma (OTSCC) has been the topic of debate since few decades. As the occult cervical lymph node metastasis is considered to be the primary prognostic factor in early OTSCC, this meta-analysis has been carried out to find the risk of regional nodal recurrence on patients kept under observation than those who have underwent Elective neck dissection (END). The articles were electronically retrieved from Ovid Medline, PubMed, Cochrane and Scholar for comparison of Observation versus END in early OTSCC. The search strategy identified 35 relevant review articles from April 1979 to April 2020 from different search engines. A total of 11,973 patients from 30 retrospective analyses, 4 prospective and 1 randomized control trials were included in this meta-analysis. Overall test revealed (OR: 13.02 95% CI 1.360–17.154) with t test 2.382 and p value 0.023 which is statistically significant and showed that END significantly reduced the risk of regional nodal recurrence. This meta-analysis finds that there is statistically significant relationship when END was performed which reduced the risk of regional nodal recurrence as seen in patients kept on Observation thereby affecting the Overall survival (OS) rate.
