5. / TITLE OF THE TOPIC / “THE CLINICOPATHOLOGICAL STUDY OF SALIVARY GLAND TUMOURS AND ITS MANAGEMENT”
6. / BRIEF RESUME OF INTENDED STUDY.
6.1 NEED FOR STUDY:
The major salivary glands include the parotid glands, the submandibular glands, and the sublingual glands. There are also approximately 750 minor salivary glands scattered throughout the submucosa of the oral cavity, oropharynx, hypopharynx, larynx, parapharyngeal space, and nasopharynx. Salivary gland neoplasms are rare and constitute 3% to 4% of head and neck neoplasms. The majority of neoplasms arise in the parotid gland (70%), whereas tumours of t ; Minor salivary glands: 25% benign and 75% malignant.(1)
The present study aims to determine the distribution, management and prognosis of various types of Salivary Gland Tumours.
6.2 REVIEW OF LITERATURE:
1. Salivary gland tumours; a study done by Dr. Dhananjay sharma concluded that salivary gland tumours though less common, are encountered in our country. Problems in their management are largely related to the facial nerve. A proper consent should thus be taken from the patient before embarking on surgery for these tomours and should be managed preferably at centers where expertise to handle complications resulting from surgery can be tackled in a proper and judicious way.
2. Salivary gland tumours – our experience; a study done by Nitin M, Sandeep Bansal concluded that in the present series of 36 patients, twenty four patients had parotid lesions while 12 had involvement of other salivary glands. There was no sex preponderance(19 males and 17 females) and no specific age group affliction, though 14/36 patients were in their third and fourth decades. At the time of the diagnosis, the age range was from 3 year to 95 year with a mean age of 49.5 years
3. Role of fine needle aspiration cytology in salivary gland pathology and its histopathological correlation; A two year prospective study in western india. A study done by Amit h Agarwal, gauravi A dhruva concluded that fnac offers valuable information which is not obtained by any other means. Fnac of the salivary gland tumours is advantageous for both the patients and clinicians because of its immediate results, accuracy, economy, lack of complications.
4. In this study, we analysed the full histological spectrum of oral salivary gland carcinomas in a consecutive data base retrieved from 3 institutions. The study confirmed MEC,ACC,and PLGA as the most common types of oral salivary gland tumours. Kaplan Meier analyses revealed comparable prognosis for these 3 major entities with no significant difference in outcome.
5. Parotid gland tumours; study done by Khalid ahsan malik.results;a total of 27 patients 15 males and 12 females,with ages ranging from 15 to 65 were included in study. Most of the patients were in the 31-50 years of age group. Pleomorphic adenoma was the commonest benign tumour with an incidence of 66.6%, while mucoepidermoid carcinoma with an incidence of 11.11% was the most common malignant tumour. They concluded that parotid gland is the principal site of salivary gland tomours.
6. A review of parotid tumours and their management;a study done by s shashinder. They concluded that the current study is small and covering ten year duration. It shows a higher proportion of malignant cases as compared to other studies. Fnac and ct scan were performed prior to the surgery were useful guidance in planning the definite operation but clinical judgment was considered more important. The incidence of complications and tumour recurrence are comparable to other international studies but the data may well be affected by the limitations of patient follow-up. Prior knowledge of anatomy and careful planning is needed to decrease the incidence of facial nerve palsy.
7. Tumors of the salivary gland are relatively uncommon and represent less than 2% of all head and neck tumors. 85% of salivary gland tumors arise within the parotid gland. The majority of these tumors are benign,with the most common histology being pleomorphic adenoma. In contrast,approximately 50% of tumors arising in the submandibular and sublingual glands are malignant. Tumors arising from minor salivary gland tissue carry an even higher risk for malignancy 75%.
8. Salivary gland tumors are rare and constitute 3% to 4% ofhead and neck tumors,most tumors arise in the parotid gland 70%,where as tumors of submandibular gland 22%,sublingual and minor salivary glands 8% are less common.
9. The histology has prognostic implications and provides information for treatment optimization.acinic cell carcinoma and grade 1&2 mucoepidermoid tumors are considered to be low grade malignancies while grade 3 mucoepidermoid tumor and other tumors are considered to be high grade malignancies.
10. Prognostic factors in malignancy of the minor salivary glands. Study done by Kwok sengloh.They concluded that the 5 and 10 year overall and DSS of minor salivary gland malignancies are good.recorrences are usually local and distant. Our data shows that surgery is the main treatment modality either alone or in combination.high grade tomors are associated with worse DSS.
6.3 Objectives of Study
1. To Study the Distribution of Salivary Gland tumour in Male and Female Population.
2. To Study the distribution of Benign and Malignant Salivary Gland tumours.
3. To Study the different Treatment Modalities/ Management in Salivary Gland Tumours.
4. To Study the Prognosis of patients after the Surgery.
