Objective: The goal of this study was to analyze the results of clinical treatment of sarcomatoid carcinoma in the parotid gland by reviewing 30 years of experience.

Methods: Thirty-five patients were enrolled in this study. The Kaplan-Meier methods were used to calculate the recurrence-free survival (RFS) and disease-specific survival (DSS) rates. The Cox model was used to determine the independent risk factor.

Results: 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-specific death was noted in 10 patients. The 5-year 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.

Conclusion: Parotid sarcomatoid carcinoma carries a poor prognosis, and perineural invasion was the most important predictive factor.
