Aggressive surgery for pancreatic duct cell cancer: feasibility, validity, limitations.
Pancreatic duct cell cancer is characterized by a low resectability rate and a low long-term survival rate. Between September 1974 and December 1992 in our institution, 149 (59%) of the 253 patients with this cancer underwent resection. The operative procedures were pancreatoduodenectomy in 105 patients, total pancreatectomy in 36, and distal pancreatectomy in 8. The tumor was extirpated with extensive dissection of the lymph nodes and excision of the nerve plexus in the retroperitoneum. Of the 149 patients, 79 (53%) underwent combined resection of the pancreas and the portal vein; 16 of the 79 patients also underwent resection of the adjacent arteries. Three patients died within 30 days after surgery, and 17 other patients succumbed within 2 to 7 months. The mortality among patients undergoing pancreatectomy and resection of the portal vein (9.5%) was similar to that of patients with pancreatectomy alone (10%). Curative resection was necessary for long-term survival. The 5-year survival rate in 61 patients with the curative resection was 15%. Ten patients lived more than 5 years. Even patients with lymph node metastases and cancer invasion of the portal vein had a prolonged survival. Intraoperative irradiation was carried out in 35 patients to improve the survival rate, but without success. Infusion chemotherapy with 5-fluorouracil via the portal vein was tried in 25 patients, resulting in a decrease in liver metastasis. We have made some progress in the first step toward improving treatment, although we are far from the goal and it is necessary to conduct additional trials.
