Abstract

Introduction: Northern part of Iran is located on the esophagus cancer belt worldwide, and North Khorasan province is considered a part of this region. This study was conducted to investigate some possible risk factors for esophageal cancer in North Khorasan province. Method: This cross-sectional study was based on esophageal endoscopy findings and histopathology reports. A total of 100 patients underwent endoscopy of whom 38 cases (19 male and 19 female) were diagnosed with esophageal cancer. Data consisted of age, gender, occupation, residential location, smoking, addiction history, education, food habits, hot tea consumption, lesion area, type of tissue, and alcohol consumption. The content and face validity of the questionnaire were investigated, followed by the evaluation of the reliability using Cronbach’s Alpha coefficient. Statistical analyses were performed using SPSS software (version 26). Results: The mean content validity index was 0.91, and Cronbach’s Alpha coefficient was obtained at 0.84. In this study, the highest incidence rates of esophageal cancer were in Bojnourd, Raz and Jargalan, Esfarayen, Maneh and Samolghan, Jajarm, and Shirvan in descending order. The mean age of patients with esophageal cancer was 66.36 years. The most common histological types of this cancer were related to squamous cell carcinoma (68.42%) and adenocarcinoma (28.94%), respectively. The distribution of esophageal carcinoma by anatomical location was 10.52% for the upper third, 26.31% for the middle third, and 63.15% for the distal third. Conclusion: It is necessary to monitor esophageal cancer continuously in North Khorasan province. This study suggests investigating how the recent pandemic of COVID-19 affects the epidemiology of esophageal cancer in the future
北呼罗珊省食管癌可能危险因素调查
简介:伊朗北部位于全球食道癌带,北呼罗珊省被认为是该地区的一部分。本研究旨在探讨北呼罗珊省食管癌的一些可能的危险因素。方法:本横断面研究基于食管内窥镜检查结果和组织病理学报告。100例患者行内镜检查,其中38例(男19例,女19例)诊断为食管癌。数据包括年龄、性别、职业、居住地、吸烟、成瘾史、教育程度、饮食习惯、热茶消费、病变面积、组织类型和酒精消费。采用Cronbach’s Alpha系数对问卷进行信度评价,并对问卷的内容和面效度进行调查。采用SPSS软件(版本26)进行统计分析。结果:平均内容效度指数为0.91,Cronbach’s Alpha系数为0.84。在本研究中,食管癌发病率最高的地区依次为Bojnourd、Raz和Jargalan、Esfarayen、Maneh和Samolghan、Jajarm和Shirvan。食管癌患者的平均年龄为66.36岁。最常见的组织学类型为鳞状细胞癌(68.42%)和腺癌(28.94%)。食管癌的解剖位置分布上三分之一为10.52%,中三分之一为26.31%,远三分之一为63.15%。结论:北呼罗珊省有必要对食管癌进行持续监测。本研究建议调查近期COVID-19大流行对未来食管癌流行病学的影响
