Abstract
The purpose of this article is to report on our study of 64 cases of submandibular gland (SMG) tumors that were operated on as first treatment at our establishment during the 24 years from September 1983 to December 2007.
We evaluated this study around patient background, diagnosis and treatment results. There were 44 benign tumors and 20 malignancies, with a mean age of 47.8 years old. In total, women were much more affected than men, but malignancies would affect men significantly compared to women. Three patients with spontaneous pain were all malignancies. The accuracy of fine needle aspiration cytology (FNAC) was 90%, while the concordance rate of histological type between FNAC and the final diagnosis was 81.8%. Three-year and 5-year survival rates were 85.1% and 48.6%, respectively.
On the other hand, we compared the present study with the “clinical review of cases with parotid tumors” which our department reported on previously. Data on tumors of SMG exceeded that of parotid tumors when regarding pre-operative diagnostic capabilities, but there were many more rates of malignant tumors and cervical lymph node metastasis shown in SMG than in the parotid gland.
