[目的]探讨辽宁省结直肠癌的内镜及病理特点。[方法]回顾性分析经肠镜及病理确诊的782例结直肠癌的内镜及病理资料。[结果]782例结直肠癌患者共808处病变(26例患者为重复癌),其中手术治疗588例。193例(24.7%)结直肠肿瘤导致结直肠梗阻或不完全梗阻。390例(49.9%)患者并发结肠腺瘤,其中进展期腺瘤120例(30.8%)。病理类型以腺癌为主(76.8%),高浸润性癌的检出率在不同年龄组之间无显著性差异(P>0.05)。青年组低分化(G3)者占36.8%,显著性高于老年组的13.0%(χ2=14.635,P<0.01)。[结论]辽宁省结直肠癌患者就诊时,近1/3患者有肠腔梗阻或不完全梗阻,约1/2患者伴发腺瘤或进展期腺瘤。早期参加筛检有利于早期发现腺瘤及早期癌变,改善结直肠癌预后。
[Objective] To investigate the endoscopic and pathological features of colorectal cancer in Liaoning Province. [Methods] The endoscopic and pathological data of 782 colorectal cancer confirmed by colonoscopy and pathology were analyzed retrospectively. [Results] A total of 808 lesions in 782 colorectal cancer patients (26 patients with recurrent cancer), of which 588 cases of surgical treatment. 193 cases (24.7%) of colorectal tumors lead to colorectal obstruction or incomplete obstruction. A total of 390 patients (49.9%) had colonic adenomas, of which 120 (30.8%) had advanced adenomas. The main pathological type was adenocarcinoma (76.8%). The detection rate of high invasive carcinoma had no significant difference between different age groups (P> 0.05). Poorly differentiated (G3) accounted for 36.8% of the youth group, significantly higher than the elderly group of 13.0% (χ2 = 14.635, P <0.01). [Conclusion] Colorectal cancer patients in Liaoning Province at the time of treatment, nearly 1/3 patients with intestinal obstruction or incomplete obstruction, about 1/2 patients with adenoma or advanced adenoma. Early screening is conducive to early detection of adenomas and early cancer, improve the prognosis of colorectal cancer.
