Abstract:
BACKGROUND: Tumors developing in the parotid gland tend to be of a large variety of histopathologic types. The relative rarity of parotid gland tumors makes epidemiologic study more difficult. To develop a rational therapeutic plan for tumors of the parotid gland, the surgeon must be fully cognizant of the factors that may affect survival. MATERIALS AND METHOD: The authors retrospectively studied 110 patients with histologically confirmed salivary gland tumor in the parotid glands at Korea Cancer Center between 1986 and 1995. We analyzed the histopatologic type and 5-year survival rate according to the some prognostic factors. RESULTS: Among the 110 patients, 39 had malignant parotid tumors. There were no recurtence in those who had parotid tumors. The overall 5-year survival rate was 62.4%. We observed statistically significant differences for patients of different clinical stages and histological grade. CONCLUSION: In summary, the clinical stage and histological grade are the significant prognostic factors, and these factors need to be considered in the treatment of parotid gland tumors.
