据大肠癌初发症状探讨临床病理学特征与预后具有重要意义。作者将896例大肠癌分为显性出血组、腹痛组、大便异常组及潜在出血组,并探讨其各自临床病理学因素。 各组均以男性较多。潜在出血组(56.1±10. 2岁)较大便异常组(60. 7±11. 9岁)、显性出血组(60.4±12.3岁)呈低龄(P<0.05)。大便异常组肿瘤直径(5.95±2.18cm)较潜在出血组(3.54±1.49cm)、显性出血组(4.87±2.20cm)呈显著差异,(P<0.01)。多发癌及重复癌合并率各组无差异,但腺癌合并率在潜在出血组高于其它组(P<0.01)。腹痛组的肝转移率及腹膜播种率均高于显性出血组(P<0.05～0.01)。切除率在潜在出血组为100％、显性出血组为94.3％、腹痛组为88.3％、大便异常组为86.6％,后者较显性出血组呈有意义
According to the initial symptoms of colorectal cancer to explore the clinical pathological features and prognosis is of great significance. The authors divided 896 cases of colorectal cancer into dominant bleeding group, abdominal pain group, abnormal stool group and potential bleeding group, and discussed their respective clinical pathological factors. Each group is more male. In the potential bleeding group (56.1±10. 2 years), the large abnormal group (60. 7±11. 9 years old) and the dominant bleeding group (60.4±12.3 years old) were young (P<0.05). The diameter of tumor in the abnormal stool group (5.95±2.18cm) was significantly different from the potential bleeding group (3.54±1.49cm) and the dominant bleeding group (4.87±2.20cm) (P<0.01). There was no difference in the rates of multiple cancers and repeat cancers in each group, but the adenocarcinoma merger rate was higher in the potential bleeding group than in other groups (P<0.01). The liver metastasis rate and peritoneal seeding rate in the abdominal pain group were higher than those in the dominant bleeding group (P<0.05-0.01). The resection rate was 100% in the potential bleeding group, 94.3% in the dominant bleeding group, 88.3% in the abdominal pain group, 86.6% in the abnormal stool group, and the latter was more significant in the dominant bleeding group.
