[The results of treatment for pancreatic cancer--statistic change].
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.
