Salivary tumors in north Jordanians: A descriptive study

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2007

Objective. To evaluate the types and distribution of tumors of salivary glands in north Jordanians. Study design. The records of the Department of Pathology at Jordan University of Science and Technology were reviewed for patients who were treated for salivary gland tumors from 1991 to 2002. The tumors were analyzed for age of patient, sex of patient, tumor site, and tumor type. Results. One hundred two true neoplasms (70% benign and 30% malignant) were found. The most frequent benign and malignant neoplasms found were pleomorphic adenoma (54%) and adenoid cystic carcinoma (13%), respectively. The most common major and minor salivary gland sites were the parotid (51%) and palatal glands (20%), respectively. Although most of major gland tumors were adenomas, carcinomas of the minor glands were only slightly less frequent than adenomas. The most frequent malignant parotid tumors were adenoid cystic carcinoma and mucoepidermoid carcinoma. The most frequent minor salivary gland malignant tumors were palatal adenoid cystic carcinoma. Age ranged from 1 to 94 (mean 40) years, with a male to female ratio of 1:1.2. Conclusion. North Jordanians with salivary gland tumors were found to have similar characteristics with patients of other countries with regard to tumor type, tumor site distribution, and age and sex of patients.

Salivary Gland Tumors in an Iranian Population: A Retrospective Study of 130 Cases

Journal of Oral and Maxillofacial Surgery, 2007

Tumors of the salivary glands are uncommon, comprising 3% to 10% of head and neck neoplasia. In the absence of epidemiologic studies of these neoplasms in an Iranian population, we conducted a preliminary survey of 130 cases over the last 20 years in Hamedan, Iran. Patients and Methods: The medical records and case notes of all patients with histologically confirmed salivary gland tumors were reviewed retrospectively from February 1984 to March 2003. This review found 89 patients with benign tumors and 41 patients with malignant tumors. The collection of data included gender, age, location, and histopathology of the tumor. Other recorded data included diagnostic procedures, operative reports, complications, additional treatment, and follow-up. Results: We studied 78 females and 52 males with a mean age of 44.9 years. Patients with benign and malignant tumors presented with a mean age of 41.3 and 47 years, respectively. The frequency of benign tumors was 68.4% (n ϭ 89) and 31.6% for malignant tumors (n ϭ 41). Tumors were localized in the parotid gland (63%; n ϭ 82), the submandibular gland (23%; n ϭ 30), and in the minor salivary glands (14%; n ϭ 18). The most common benign tumor was pleomorphic adenoma (65.4%; n ϭ 85). Among malignant tumors, mucoepidermoid carcinoma was the most frequent (11.5%; n ϭ 15), followed by adenocarcinoma (10%; n ϭ 13). Greater than 63% of malignant tumors were treated surgically, and the remaining with combined therapy. Seven patients died over the follow-up period (6 with persistent disease), 5 were lost to follow-up, and 23 remained cancer-free. Conclusion: Between benign and malignant salivary gland tumors, frequency of pleomorphic adenoma and mucoepidermoid carcinoma was in keeping with studies reported previously. In other salivary gland tumors, however, diversity was obvious and showed significant difference, requiring further studies.

Salivary gland tumors: a 15-year experience of a universıty hospital in Turkey

Northern Clinics of Istanbul

T he salivary glands consist of three major glands as parotid, submandibular and sublingual glands and hundreds of minor glands, which are diffusely located in the beginning part of the respiratory system. Tumors of the salivary glands are rarely encountered. However, they appear with different histopathological characters. Different biological behaviors can be observed even in neoplasms defined by the same name. In the latest classification made by the World Health Organization (WHO) in 2017, salivary gland tumors were classified into more than 30 benign and malignant histologic subtypes [1]. This wide histopathological spectrum and significant differences in prognosis between them distinguish salivary gland tumors from other organ neoplasms. Salivary gland tumors account for approximately 3-4% of all head and neck tumors [2]. Their inci-ABSTRACT OBJECTIVE: To determine the demographic characteristics of benign and malignant salivary gland tumors in our department in the last 15 years. METHODS: In this study, the files of the patients who underwent salivary gland surgery between 2004 and 2019 in our department were analyzed retrospectively. A total of 366 patients whose diagnoses of salivary gland tumor histopathologically confirmed were included in this study. The demographic data of the patients and tumor localizations were recorded, and their relationships with histopathological results were examined. RESULTS: Of the 366 tumors, 292 (80%) of them was originated from the parotid gland, 52 (14%) from the submandibular gland, and 22 (6%) from the minor salivary gland. The male: female ratio was found as 1.2:1, and the mean age of the patients was 50.37 years. A total of 259 (70.8%) tumors were benign, and 107 (29.2%) were malignant. The most frequent benign tumor was pleomorphic adenoma, with 121 cases (46.7%). While pleomorphic adenomas constituted the majority of the benign tumors of the submandibular gland and minor salivary glands, Warthin tumor was detected more than pleomorphic adenoma in the parotid gland. The most common malignant tumor was mucoepidermoid carcinoma, with 26 cases (24.3%). CONCLUSION: The distribution of the salivary gland tumors detected in our department was found to be substantially similar to other worldwide series. Unlike the literature, we concluded that salivary gland tumors were seen slightly more in males, minor salivary gland tumors were relatively rare and Warthin tumors were more frequently detected in our region.

Minor salivary gland tumors in a Nigerian Hospital: a retrospective review of 146 cases

Odonto-stomatologie tropicale = Tropical dental journal

This is a retrospective study of the location, diagnosis, sex and age distribution and treatment of minor salivary glands tumours of the upper aero digestive tract in Lagos, Nigeria. Case files and radiographs of patients treated over a 24-year period were reviewed. These tumours constituted 40.4% of all salivary gland tumours in the series. The majority (62.3%) of these tumours was malignant, and the most common malignant tumour was mucoepidermoid carcinoma (19.2%). However, pleomorphic adenoma (34.2%) was the most common tumour overall. Both benign (67.2%) and malignant (23.9%) tumors were most frequently located in the palate. Both sexes were equally affected (Male-female ratio 1 to 1), but a higher proportion of benign tumours were found in the palate of females (75%) than their male counterparts (64%). Patients with adenoid cystic carcinoma were significantly older at presentation than those with pleomorphic adenoma and adenocarcinoma (P < 0.05). These findings show that maj...

Retrospective study of 124 cases of salivary gland tumors and literature review

Journal of Clinical and Experimental Dentistry

Background: Salivary gland tumors are a rare and morphologically diverse group of lesions and their frequency is still unknown in several parts of the world. The knowledge of its population characteristics contributes to a better understanding of its etiopathogenesis. Objectives: This study investigated the frequency of salivary gland tumors in a region of southern Brazil and compared these data in a literature review. Material and Methods: A retrospective study was conducted of salivary gland tumors diagnosed at two pathology centers from 1995 to 2016. Patient age and gender, tumor site and frequency, histopathological diagnosis, and symptomatology were evaluated. Chi-squared tests were used to assess the associations between variables. To compare our data, we also conducted a literature review of publications in the PubMed and LILACS databases of retrospective studies of salivary gland tumors. Results: A total of 124 salivary gland tumor cases was identified, 81 (65.3%) of which were classified as benign and 43 (34.6%) as malignant. Most tumors occurred in the parotid gland (57.2%). Pleomorphic adenoma was the most common tumor (59.6%), followed by adenocarcinoma not otherwise specified (8.8%). The tumors occurred more often in women (54.8%) than in men (45.2%). Malignant tumors were associated with pain in 31.4% of cases (p <0.05). The literature review included 35 articles from different countries. Women were most affected, with a mean age of 41.7 years. The most common benign tumor was pleomorphic adenoma (48.2%) and the most common malignant tumor was mucoepidermoid carcinoma (8.7%). Conclusions: The results of the present study showed that salivary gland tumors are rare. The parotid gland is the most common location and pleomorphic adenoma are the most frequent lesions. The malignant tumors presented as several histological types and the incidence was variable globally.

Salivary Gland Tumors in Maxillofacial Region: A Retrospective Study of 130 Cases in a Southern Iranian Population

Pathology Research International, 2011

Tumors of the salivary glands are uncommon head and neck neoplasia. We conducted a retrospective study of 392 cases over the last 6 years in Shiraz, south of Iran, to investigate the clinicopathological features of these tumors in Iranian population. The age of the patients ranged from 8 to 85 years, with the mean age 44.57 ± 14.65 years and male-to-female (M : F) ratio was 1.02 : 1. For benign tumors, there was a propensity towards females, whereas the malignant tumor was more common in males. The ratio of benign tumors to malignancies was 2.19 : 1. Pleomorphic adenoma (PA) was the most common tumor and accounted for 85% of all benign tumors, followed by Warthin's tumor (8.6%). Of the 125 malignancies, adenoid cystic carcinoma (40%), mucoepidermoid carcinoma (24%) and invasive squamous cell carcinoma (16%) were the most common histological types. Most of the salivary gland tumors (75%) originated from major salivary glands and the remained (25%) originated from minor glands. The parotid gland was the most common site both in benign and malignant tumors. Most of our findings were similar to those in the literature, with some variations. The salivary tumors slightly predominated in males. Adenoid cystic carcinoma and mucoepidermoid carcinoma constituted the most common malignancies.

Medicina Oral Patología Oral y Cirugia Bucal, 2010

Objective: This retrospective study aimed to investigate the types and distribution of neoplasm of salivary glands in a Turkish population. Study Design: The histological diagnosis records of the Department of Pathology at Cumhuriyet University were reevaluated for 125 patients who were treated for salivary gland tumors from 1987 to 2008. The neoplasms were analyzed for histological diagnosis, age, sex, and site. The histological diagnoses were analyzed according to the 2005 WHO classification. Results: A total of 125 primary salivary gland neoplasms, consisting of 95 (76%) benign and 30 (24%) malignant groups were recorded. The most common major and minor salivary gland sites were the parotid (61.6%) and palatal glands (9.6%), respectively. Pleomorphic adenoma was the most frequent benign tumor followed by Warthin's tumor. Among the malignant group, adenoid cystic carcinoma was the most prevalent. Age for all cases ranged from 16-80 years; mean age was 41.97 years, with a female to male ratio of 1:1.15. Conclusions: Although there were some discrepancies, the characteristics of salivary gland tumors of Turkish patients are in line with those of patients from other countries according to tumor type, tumor site distribution, and age and sex of patients.

Salivary gland neoplasms: an analysis of 74 cases

Journal of Maxillofacial and Oral Surgery, 2009

cases of salivary gland neoplasms were analyzed retrospectively, of which 44 (60%) were benign and 30 (40%) malignant. 61 % percent of neoplasms were in the parotid gland, 22% in the minor salivary glands including sublingual salivary glands, and 17% in the submandibular glands. The most common benign neoplasm was pleomorphic adenoma (64%), and the most common malignant neoplasm were adenoid cystic carcinoma (17%) and mucoepidermoid carcinoma (23%).We analyze the incidence and distribution of all types of salivary gland neoplasms in our series, and provide data for comparison with other epidemiological studies from different geographical sites and races. Demographic data from these studies help us to a better understanding of the biological and clinical characteristics of the disease. Further epidemiological surveys should be encouraged for better understanding of the disease and to provide early and better treatment of salivary gland neoplasms
