因胰腺的解剖位置较隐蔽,故胰腺癌不易早期发现,且预后较差。1987年日本报道,胰腺癌手术切除后5年、7年生存率分别是、18.9％和16.0％,远高于保守治疗的2.4％和1.6％,故手术是治疗胰腺癌的主要方法。本研究中,T_1期(肿瘤小于2cm)和T_2期(肿瘤2.1～4.0cm)胰腺癌的手术切除率分别是90.9％和77.3％,而T_3期(肿瘤4.1～6.0cm)和T_4期(肿瘤大于6.0cm)则分别是40.9％和17.1％,
Because the anatomical location of the pancreas is hidden, pancreatic cancer is not easy to find early, and the prognosis is poor. In 1987 Japan reported that the 5-year and 7-year survival rates after pancreatic cancer resection were 18.9% and 16.0%, respectively, which were much higher than 2.4% and 1.6% of conservative treatments. Therefore, surgery is the main method for the treatment of pancreatic cancer. In this study, surgical resection rates for T 1 (tumor less than 2 cm) and T 2 (2.1 to 4.0 cm) pancreatic cancers were 90.9% and 77.3%, respectively, whereas T 3 (tumors 4.1 to 6.0 cm) and T 4 (tumors). More than 6.0cm) are 40.9% and 17.1% respectively.
