收集我院有随访结果的大肠癌根治手术后病例431例。病理观察记录采用全国大肠癌病理分析卡.项目归并为14项36个因素。因素量化后输入微机,按低标准 F=2.0和高标准 F=9.0两种方法,分别筛选出判断预后有意义的因素建立数学模型Ⅰ、Ⅱ、Ⅲ、Ⅳ方程。按方程计算出■≥3.0时预后较好,可望存活5年以上。■<3.0时则预后较差,存活在5年以下。筛选出对预后影响较大的因素有低分化腺癌、粘液腺癌、癌浸润肠壁深度、间质细胞及纤维反应、淋巴结转移情况等。经考核组内检验准确率为83.9～91.9%。组外检验准确率为82.9～88.5%。
We collected 431 cases of colorectal cancer after radical surgery in our hospital. Pathological observations were performed using the national colorectal cancer pathology analysis card. The project was integrated into 14 36 factors. After the factors were quantified, they were input into the computer, and according to the low standard F=2.0 and the high standard F=9.0, the factors that determine the prognosis were selected to establish mathematical equations I, II, III, and IV equations. According to the equation, the prognosis is better when it is greater than or equal to 3.0, and it is expected to survive for more than 5 years. ■<3.0 is a poor prognosis and survives for less than 5 years. The factors that affected the prognosis were poorly differentiated adenocarcinoma, mucinous adenocarcinoma, depth of intestinal infiltration, interstitial cells and fibrosis, and lymph node metastasis. The accuracy rate within the assessment group was 83.9 to 91.9%. The out-of-group inspection accuracy rate was 82.9 to 88.5%.
