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 surteon 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.
