Oral cancer is the sixth most common form of cancer reported globally which includes lip, tongue, mouth, and throat. Developing countries face several challenges to identify and remove potential risk factors. Chewing tobacco/pan masala is considered to be the most potential risk factor for oral precancerous lesions and oral cancer.
To study the clinical-epidemiological profile of oral cancer cases and potential risk factor associated with it.
This is cross-sectional study which includes all major tertiary hospital in Lucknow district. Five hundred and eight cases of oral cancer reported in all major tertiary hospitals in Lucknow district during 2013-2016.
Clinicoepidemiological characteristics of oral cancer cases.
percentages, proportions.
Out of 508 cases, majority of the subjects included in the study belonged to 18-75 years age group. Reported cases of oral cancer in males were higher as compared to females. Most of the subjects belonged to lower middle and upper lower socioeconomic group. It was found that 199 (39.2%) subjects consumed smokeless tobacco. Buccal mucosa was the common site of oral cancer being present in 50.4% of the subjects. Histopathologically, 256 cases of buccal mucosa, 17 cases of lip, 33 cases of alveolar region, 16 cases of mandible region, 156 cases of tongue region, 7 cases of gingival buccal sulcus region, and 23 cases of palate were diagnosed as oral squamous cell carcinoma.
In the present study, the most affected site was buccal mucosa (50.4%), tongue (30.7%), and other diagnosis was <10%.
口腔癌是全球报告的第六大常见癌症形式，包括唇癌、舌癌、口腔癌和喉癌。发展中国家在识别和消除潜在风险因素方面面临诸多挑战。咀嚼烟草/嚼烟被认为是口腔癌前病变和口腔癌最主要的潜在风险因素。
研究口腔癌病例的临床流行病学特征及其相关潜在风险因素。
这是一项横断面研究，涵盖勒克瑙地区所有主要的三级医院。2013年至2016年期间，勒克瑙地区所有主要三级医院报告的508例口腔癌病例纳入研究。
口腔癌病例的临床流行病学特征。
百分比、比例。
在508例病例中，研究纳入的大多数受试者年龄在18至75岁之间。报告的口腔癌男性病例多于女性。大多数受试者属于中低收入和中高收入社会经济群体。发现199名（39.2%）受试者使用无烟烟草。颊黏膜是口腔癌最常见的部位，占受试者的50.4%。组织病理学上，256例颊黏膜、17例唇、33例牙槽区域、16例下颌区域、156例舌区域、7例牙龈颊沟区域和23例腭被诊断为口腔鳞状细胞癌。
在本研究中，受影响最严重的部位是颊黏膜（50.4%）、舌（30.7%），其他诊断比例<10%。
