[目的]探讨青年结直肠癌患者内镜特点及病理特征。[方法]比较青年结直肠癌患者(n=61)与老年结直肠癌患者(n=213)的内镜资料与病理特征。[结果]青年患者结直肠各部位均可发病,右半结肠发病率为40%(25/61),高于老年组的28.2%(60/213)(P<0.05);大体病变形态青年组浸润型较多(52.5%,32/61),老年组隆起型为多(50.2%,107/213)(P<0.05);在病变侵及肠管周径上,两组无差异(P>0.05);组织病理学上,青年组以低分化腺癌、黏液腺癌较多,老年组以中、高分化腺癌为多。[结论]青年结直肠癌患者病灶位置分布均匀,多为浸润型,组织分化较差。
[Objective] To investigate the endoscopic characteristics and pathological features of young patients with colorectal cancer. [Methods] Endoscopic data and pathological features of young patients with colorectal cancer (n=61) and elderly patients with colorectal cancer (n=213) were compared. [Results] The incidence of colorectal cancer was positive in young patients. The incidence of right colon was 40% (25/61), which was higher than 28.2% (60/213) of the elderly group (P<0.05). The infiltration type was more (52.5%, 32/61), and the uplift type in the elderly group was more (50.2%, 107/213) (P<0.05); there was no difference between the two groups in the pathological changes and invasion of the intestine (P>0.05). Histopathologically, the young group had poorly differentiated adenocarcinomas and mucinous adenocarcinomas. The elderly group had more moderately-differentiated adenocarcinomas. [Conclusion] The lesions in young patients with colorectal cancer were distributed evenly, and most of them were infiltrating and poorly differentiated.
