Sixty-nine patients with hepatocellular carcinoma underwent curative hepatic resections as primary cases from 1981 to 1986. Seven patients died in the hospital after operation. The other 62 patients left the hospital and were closely followed for 25 to 78 months. Recurrence of carcinoma became obvious in 41 (66%) of 62 patients. The clinical and pathologic features of these 41 patients were not significantly different from those of the other patients. Recurrent tumors were found in the residual liver in 38 patients (93%), in the bone in 2 (5%), and in the lung in 1 (2%). Recurrence was diagnosed within 1 year, between 1 and 2 years, and more than 2 years after the operation in 22 (56%), 10 (26%), and 7 (18%) patients, respectively. It was difficult to determine the exact time of recurrence in two patients. There was a significant negative correlation between the size of primary tumor and time until recurrence; the larger the primary tumor, the shorter the time until recurrence. Among the 29 patients who underwent local excisions for their primary tumors, 19 recurrences were observed. Eighteen were found in the residual liver, in the same segment as the primary tumor, or in one near it. Larger hepatic resection for primary tumors is thus advocated to prevent recurrence.

BackgroundThe high recurrence rate after surgery for colorectal cancer liver metastasis (CLM) remains a crucial problem. The aim of this trial was to evaluate the efficacy of adjuvant therapy with uracil-tegafur and leucovorin (UFT/LV).MethodsIn the multicenter, open-label, phase III trial, patients undergoing curative resection of CLM were randomly assigned in a 1:1 ratio to either the UFT/LV group or surgery alone group. The UFT/LV group orally received 5 cycles of adjuvant UFT/LV (UFT 300mg/m2 and LV 75mg/day for 28 days followed by a 7-day rest per cycle). The primary endpoint was recurrence-free survival (RFS). Secondary endpoints included overall survival (OS).ResultsBetween February 2004 and December 2010, 180 patients (90 in each group) were enrolled into the study. Of these, 3 patients (2 in the UFT/LV group and 1 in the surgery alone group) were excluded from the efficacy analysis. Median follow-up was 4.76 (range, 0.15–9.84) years. The RFS rate at 3 years was higher in the UFT/LV group (38.6%, n = 88) than in the surgery alone group (32.3%, n = 89). The median RFS in the UFT/LV and surgery alone groups were 1.45 years and 0.70 years, respectively. UFT/LV significantly prolonged the RFS compared with surgery alone with the hazard ratio of 0.56 (95% confidence interval, 0.38–0.83; P = 0.003). The hazard ratio for death of the UFT/LV group against the surgery alone group was not significant (0.80; 95% confidence interval, 0.48–1.35; P = 0.409).ConclusionAdjuvant therapy with UFT/LV effectively prolongs RFS after hepatic resection for CLM and can be recommended as an alternative choice.Trial RegistrationUMIN Clinical Trials Registry C000000013

Internal stenting of the hepaticojejunostomy and pancreaticojejunostomy was performed in 11 consecutive patients undergoing pancreatoduodenectomy between July 1992, and July 1994, to promote earlier discharge from hospital. Although minor leakage of the pancreaticojejunostomy occurred in 4 patients, this resolved within a short period and all 11 patients were able to be discharged by the 29th postoperative day in good health and without any intubation. Follow-up abdominal X-ray and computed tomography (CT) scans proved that all 22 of the stenting tubes had spontaneously fallen out by the 176th postoperative day. No complication related to the stenting tubes occurred in any of our patients.

A 66-year-old man, who had ascending colon cancer which invaded the duodenum, pancreas, and superior mesenteric vein, underwent a curative resection including an extended right hemicolectomy, pylorus-preserving pancreatoduodenectomy, and a partial resection of the superior mesenteric vein. The pathological examination revealed adenocarcinoma of the colon, which directly invaded the duodenum and pancreas, thus causing duodenocolic fistula. Tumor infiltration to the superior mesenteric vein was not histologically proven. Two out of 40 lymph nodes were also involved. The patient is still alive and disease-free 37 months after the operation. A 72-year-old man, with a history of surgery two previous times for ascending colon cancer and its recurrence, underwent a third operation including a resection of the former ileocolic anastomosis en bloc by means of a pylorus-preserving pancreatoduodenectomy with a curative intent. The pathological examination revealed adenocarcinoma of the colon, which directly invaded the duodenum and pancreas. Seven out of 31 lymph nodes were also involved. The patient died of recurrence 24 months after the third operation. These two cases demonstrated the usefulness of a resection of the colon en bloc by means of a pancreatoduodenectomy in patients with either locally advanced colon cancer or locally advanced recurrent colon cancer.
