Bioptates and resected material from patients treated for cancer of the esophagus at the Kazakh Research Institute of Oncology in 1980-1989 were analysed. Adenogenic tumors made up 6.0% of the 1671 cases of esophageal cancer studied. A gradual increase in the percentage of adenogenic cancers was established (P < 0.05). A group of 100 cases of adenogenic cancers was examined in detail. Adenocarcinoma made up 5.3%, adenosquamous cancer--0.5 and adenocystic cancer--0.2%. Adenogenic cancers most often occurred in the lower thoracic part of the organ. Poorly differentiated adenocarcinoma predominated (56.8%), with a tendency to an increase in the tumor occurrence in the upper and mid-thoracic parts. The enhanced morbidity from adenogenic cancers is attributed to a high occurrence of esophagitis in the majority of regions of Kazakhstan.
对1980 - 1989年哈萨克斯坦肿瘤研究所收治的食管癌患者的活检组织和切除标本进行了分析。在1671例研究的食管癌病例中，腺源性肿瘤占6.0%。腺源性癌的百分比呈逐渐上升趋势（P < 0.05）。对100例腺源性癌病例进行了详细检查。腺癌占5.3%，腺鳞癌占0.5%，腺囊癌占0.2%。腺源性癌最常发生在食管的下胸部。低分化腺癌占主导（56.8%），且在上胸部和中胸部肿瘤发生率有增加趋势。哈萨克斯坦大部分地区食管炎高发被认为是腺源性癌发病率增加的原因。
