The Kaplan\u2010Meier methods were used to calculate the recurrence\u2010free survival (RFS) and disease\u2010specific survival (DSS) rates. The Cox model was used to determine the independent risk factor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Mean age at presentation was 57.8 years, and most of the patients were staged as tumor (T)3 or T4. Perineural invasion was noted in 15 (42.9%) patients. Fifteen (42.9%) patients received neck dissection due to clinically suspicious nodes. Of those, three patients had pathologically positive nodes. Recurrence was noted in 14 patients; the most common pattern of treatment failure was local recurrence, and only 40% of the patients could receive salvaged surgical treatment. Disease\u2010specific death was noted in 10 patients. The 5\u2010year RFS and DSS rates were 67.3% and 65.7%, respectively. In a multivariate analysis, only the factor of perineural invasion was independently correlated with death.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Parotid
