目的 总结分析缩窄型(浸润型)直肠癌临床病理学特征,以指导治疗。方法 回顾分析35例缩型直肠癌临床病理学资料,并随机抽取80例非缩窄型直肠癌临床病理学资料进行对照分析,并用常规统计学方法处理所得结果。结果 (1)缩窄型直肠癌发病率低,占2.83％。(2)病理组织学类型以粘液腺癌、低分化腺癌为主。分化差的所占比例明显高于对照组。(3)在病理分期及根治率方面无显著差别。(4)缩窄型直肠癌预后差,三、五年生存率明显低于对照组。结论 缩窄型直肠癌预后差,欲提高其生存率必须提高其早期诊断、早期治疗,在根治手术的基础上重视综合治疗。
Objective To summarize and analyze the clinicopathological characteristics of constrictive (infiltrating type) rectal cancer to guide the treatment. Methods The clinical and pathological data of 35 cases of rectum colorectal cancer were retrospectively analyzed. The clinical and pathological data of 80 cases of non-constrictive rectal cancer were randomly selected for comparative analysis. The results were obtained by routine statistical methods. Results (1) The incidence of constrictive rectal cancer is low, accounting for 2.83%. (2) histopathological types of mucinous adenocarcinoma, poorly differentiated adenocarcinoma based. The proportion of poor differentiation was significantly higher than the control group. (3) No significant difference in pathological staging and cure rate. (4) The narrow type rectal cancer has poor prognosis, and the three and five year survival rates are obviously lower than those in the control group. Conclusions The narrowing type rectal cancer has a poor prognosis. To improve its survival rate, its early diagnosis and early treatment must be improved. Comprehensive treatment should be emphasized on the basis of radical operation.
