Chronic alcohol consumption carries a high risk for oral and pharyngeal cancers among persons who have never smoked. Excessive alcohol consumption displays cytogenetic changes in oral mucosa cells. Cytomorphometric analysis of oral mucosal cells helps in the early detection of cytomorphological transformations in alcoholics before and after the onset of carcinoma.
A prospective, hospital-based, comparative study was done after written informed consent. Smears were obtained from the clinically normal buccal mucosa of 102 randomly selected alcoholic patients attending the medicine outpatient department aged above 25 years who consumed a minimum of 45 ml alcohol per day for at least 10 years and of 102 nonalcoholics as control. The slides were immediately fixed in absolute methanol and stained by the Papanicolaou (Pap) staining technique. PAP-stained smears were examined under the light microscope. Using the image J 1.47 image analysis software, a morphometric analysis of around 50 cells/case was done.
A statistically significant increase in mean cytoplasmic area ( < 0.001), mean nuclear area ( < 0.01), and cell-to-nuclear parameter ratio ( < 0.001) was seen in the alcohol group in comparison with the control group.
Prolonged consumption of alcohol produces cytomorphometric changes in buccal mucosal cells before the onset of premalignant lesions.
在从不吸烟的人群中,长期饮酒会使患口腔癌和咽癌的风险升高。过量饮酒会导致口腔黏膜细胞出现细胞遗传学变化。对口腔黏膜细胞进行细胞形态计量分析有助于在酗酒者癌变前后早期检测出细胞形态学转变。
在获得书面知情同意后,开展了一项基于医院的前瞻性对照研究。从102名年龄在25岁以上、每天至少饮用45毫升酒精且饮酒至少10年的内科门诊随机选取的酗酒患者以及102名作为对照的非酗酒者的临床正常颊黏膜获取涂片。涂片立即用纯甲醇固定,并用巴氏染色技术染色。在光学显微镜下检查巴氏染色涂片。使用Image J 1.47图像分析软件,对每个病例约50个细胞进行形态计量分析。
与对照组相比,酒精组的平均细胞质面积(<0.001)、平均细胞核面积(<0.01)和细胞与细胞核参数比(<0.001)有统计学显著增加。
长期饮酒会在癌前病变出现之前使颊黏膜细胞产生细胞形态计量变化。
