A Clinical Study Of Salivary Gland Tumors In Korean(The Classification of benign and malignant tumors and their individual prognosis)

A statistical data of salivary gland tumor classification and treatment and their individual prognosis were analyzed, and their clinical, pathological characteristics were reviewed Especially malignant tumors, their individual survival rate was calculated and would like to contribute in early diagnosis and enhancement of future treatment plan. The results are as follows 1. Based on 1992 year WHO classification, salivary gland tumors were classified with 74 cases; of benign tumors(41.81%), 91 cases of malignant tumors(51.41%) and 12 cases of inflammation diseases(6.78%) as sialadenitis, necrotizing sialometaplasia. 2. In a total of 177 cases, 108 cases of female showed higher gender ratio by 1 : 156, and age distribution was 7 to 93 years with mean age was 45. The most predilected decade was 5th with 45 cases (25.42%). 3. The chief complaint diagnosed as salivary gland tumors was pain, and the sublective duration was vaned from 5 days to 20 years, with mean 10 weeks. 4. The lesion size of salivary gland tumors was vaned from superfical lesion to deep invasive lesion and their mean size was 2.18 cm. 5. The predilection site of salivary gland tumors was minor salivary gland on palate with 83 cases(46.89%), and 37 cases(20.90%) were on the parotid, 13 cases(7.3%) were on the submandibular gland 6. The five year survival rate using Kaplan-Meier product limit method ot salivary gland tumors was 61.23% and eight year survival rate was 29.12% According to stage, the five and eight year survival rate of stage I was 89.70%, 61.23%, stage II was 83.27%, 72.82%, stage III was 62.75%, 38.42%, stage IV was 54.21%, 24.31%, respectively. 7. In stage IV patients of salivary gland tumors, five and eight year survival rate of the patients with neck dissection was 62.49%, 30.28%, respectively, and this is superior to that of the patients without neck dissection with 54.39%, 26.39%. 8. The five year survival rate of the patients with cervical metastasis was 53.24% and that of the patients without cervical metastasis was 72.48 and 34.28% was that of the patients with distant metastasis. 9 According to the classifications of malignant tumors, their individual treatment and prognosis were analyzed.
