Between 1981 and 1995, 17, 121 patients with pancreatic cancer were registered by Japan Pancreas Society (JPS). The resection rate was 36.1% with recent increase. The 1, 3, and 5 year actuarial survival rates of resected cases were 52.7%, 24.0%, and 18.6%, respectively. As for resectional procedures, there was a gradual decrease in TP and increase in PD. Lymph node metastases are found in 37.0% of patients with tumor size less than 2 cm, therefore, and extended lymphadenectomy and extended surgery including portal vein resection are more performed than before in Japan. Tubular adenocarcinoma are 60.6% in all registered pancreatic cancer, but its survival rate is only 10%. The survival rate of the National Cancer Data Base was almost the same as that of us with higher resection rate, but we cannot easily accepted its fact as the background of patients are various.
1981年至1995年间，日本胰腺学会（JPS）登记了17121例胰腺癌患者。切除率为36.1%，且近期有所上升。切除病例的1年、3年和5年精算生存率分别为52.7%、24.0%和18.6%。至于切除手术，胰十二指肠切除术（TP）逐渐减少，胰头十二指肠切除术（PD）逐渐增加。肿瘤大小小于2cm的患者中，37.0%发现有淋巴结转移，因此，在日本，扩大淋巴结清扫术以及包括门静脉切除在内的扩大手术比以前实施得更多。所有登记的胰腺癌中，管状腺癌占60.6%，但其生存率仅为10%。国家癌症数据库的生存率与我们的几乎相同，但切除率更高，不过鉴于患者背景各异，我们难以轻易接受这一事实。
