Abstract
Objective: Whether to administer adjuvant treatment is a matter of great debate for oral cavity cancer harboring a single positive node without extranodal extension and positive margin (defined as low/intermediate risk pN1new in this study). Methods: A total of 243 low/intermediate risk pN1new patients with oral cavity cancer who received curative surgery were included. Overall survival (OS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), and distant metastasis-free survival (DMFS) were compared between patients receiving adjuvant treatment and observation alone. Results: For patients receiving adjuvant therapy vs observation, the differences in outcomes were not statistically significant in terms of 5-year OS, LRFS, RRFS, and DMFS. For subgroup analysis, in low/intermediate pN1new patients with one or more minor risk factors, adjuvant therapy was not significantly associated with OS, LRFS, RRFS, or DMFS in pN1new patients. Conclusion: For low/intermediate risk pN1new patients with oral cavity cancer, adjuvant therapy might be omitted. Level of Evidence: 4.
