The results and problems of extensive radical surgery for carcinoma of the head of the pancreas

Since 1973, 152 patients with pancreatic carcinoma have undergone surgery in our clinic, including 110 with carcinoma of the head of the pancreas. Of these 110 patients, resections were performed on 43 (39.1 per cent), 33 (30 per cent) of whom underwent a curative resection based on macroscopic evidence. Six of the patients who underwent macroscopic curative resection survived for five years, giving a five-year survival rate of 36.5 per cent by the Kaplan-Meier method after excepting 6 operative deaths. We compared the extent of pancreatic cancer by constructing survival curves according to the General Rules published by the Japan Pancreas Society. There was no statistical difference in survival based on tumor size or stage, however, there was a significant difference in the survival curves of so and se, being the absence or presence of the anterior capsule of the pancreas, rpo and rpe, being the absence or presence of invasion of the retroperitoneal tissue; ew(−) and ew(+) being the absence or presence of invasion at the surgical margin of resection, or n0 and n1 being the extent of lymph node metastasis. The results of this comparison suggest that extended radical pancreatectomy may be indicated for the treatment of pancreatic cancer as the standard radical operation for pancreatic cancer may miss tumors which have spread to the retroperitoneum and extrapancreatic nerve plexus.
