The Pancreatic Cancer Registry of the Japan Pancreas Society registered 11,317 patients of pancreatic cancer during these ten years. Among these patients, resectional procedures were performed on only 3,743 cases (33.1%). The actual 5-year survival rate of the patients who underwent resection was 16.6%. As for small cancer which was less than 2cm, the 5-year survival rate was 41.0%. In pancreatic cancer local recurrence was more frequent than other cancers of pancreatic head lesions. Extended operation which means lymphangiectomy more than R2 has not improved survival rate generally But some patients who underwent extended operation have survived long period. Multi-disciplinary treatment of pancreatic cancer has been tried.
