口腔癌是印度低社会经济群体中迅速增长的疾病。由于吸烟和咀嚼烟草的原因，社会和经济边缘化的人群患口腔癌的风险较高。为了评估印度普外科门诊中出现的癌前病变和口腔癌患病率，并评估烟草是否是诱发因素。本研究分析了658名低社会经济群体印度人的癌前病变和口腔恶性肿瘤发生率。来诊的病人主要有口腔疼痛、灼烧或溃疡等症状，临床评估了口腔内是否有组织增生、皮革样变化、溃疡性变化以及口腔内的白色或红色病变。结果：本研究中，无烟烟草和吸烟烟草的总患病率分别为78.8%（n=518）和65.2%（n=429）。大约39.8%（n=262）的样本呈阳性，存在口腔癌前病变和癌症病变。呈阳性的样本中，颊粘膜有最多的患者，达到36.2%（n=238），而唇粘膜患者占6.1%（n=40）。由于高烟草消费率和烟草习惯，印度人患口腔癌的患病率很高，因此应将戒烟中心作为优先考虑。此外，早期发现和筛查对于获得更好的结果至关重要。需要设立更多的戒烟中心，以阻止烟草习惯，并通过早期诊断来预防异型性变化。版权所有 © 2023, Taruna et al.

 Oral cancer is a rapidly growing disease among Indian subjects mainly in the low socioeconomic group. Socially and economically marginalized subjects are at high risk for oral cancer because of smoke and smokeless tobacco consumption. To evaluate the prevalence of precancerous lesions and oral cancer and evaluate tobacco as a causative factor in Indian subjects visiting the outpatient department of the institute. Around 658 subjects were analyzed for frequency of premalignant lesions and oral malignancy in Indian subjects from the low socioeconomic group. Patients visited for pain, burning, or ulceration in the oral cavity were clinically assessed for any tissue growths, leathery alterations, ulcerative changes, and white or red lesions in the oral cavity.  Results: The overall prevalence of smokeless and smoking tobacco was 78.8% (n=518) and 65.2% (n=429) respectively in the present study. Around 39.8% (n=262) of samples were stained positive for precancerous and cancerous lesions of the oral cavity. The highest number of positive samples were from buccal mucosa with 36.2% (n=238) subjects and 6.1% (n=40) for labial mucosa. Oral cancer is highly prevalent in Indian subjects owing to high tobacco consumption rates and habits warranting the cessation center a priority. Also, early detection and screening are vital to attaining better outcomes. More tobacco cessation centers are needed to stop the habit and early diagnosis will prevent dysplastic changes.Copyright © 2023, Taruna et al.
