Outcome of Hepatectomy for Huge Hepatocellular Carcinoma

PURPOSE: In spite of the recent improved results of hepatectomy for huge hepatocellular carcinomas (HCC), the prognosis of patients with huge HCCs is still poor compared to that of patients with small HCCs. This study was performed to compare the results of hepatectomy between patients with huge HCCs and those with small HCCs, to identify the prognostic factors in patients with huge HCCs, and to determine the preoperative selection criteria. METHODS: We retrospectively analyzed 51 patients who underwent hepatectomy, between July 1994 and February 2009 at Dankook University Hospital. Patients with HCC> or =10 cm were classified in large (L) group and others were classified in small (S) group. The clinicopathological features, operative procedures, and postoperative outcome were compared between both groups and various prognostic factors were investigated in group L. RESULTS: Eleven patients were classified in group L. Tumor size, vascular invasion, and tumor stage were higher in group L. Postoperative morbidity was higher in group L, but mortality was not different between the groups. Disease-free survivals were significantly lower in group L than in group S (36.4%, and 24.2% vs. 72.0%, and 44.0% for 1- and 3-year), but overall survival rates were similar in both groups (45.5%, and 15.2% in group L vs. 60.3%, and 41.3% in group S for 3- and 5-year). Presence of satellite nodules was the only prognostic factor in multivariate analysis after surgery for huge HCC. CONCLUSION: Regardless of tumor size, huge HCCs deserve consideration for surgery in patients with preserved liver function. Furthermore, the effect of surgery could be maximized with appropriate selection criteria, such as huge HCC without satellite nodules.

Prognostic Factors after Major Resection for Distal Extrahepatic Cholangiocarcinoma / 대한소화기학회지

BACKGROUND/AIMS: Although diagnosis and surgical treatment for distal common bile duct cancer have enormously advanced, survival is not satisfactory and its prognostic factors are still being debated. Thus, we evaluated the outcomes and prognostic factors after major resection for distal extrahepatic cholangiocarcinoma (dCC). METHODS: One hundred and fifty-four patients who underwent major resection such as pancreaticoduodenectomy for dCC were retrospectively analyzed. We investigated clinical features, postoperative complications, survival, and prognostic factors of dCC. CONCLUSIONS: One hundred and three (66.9%) male and 51 (33.1%) female patients were enrolled and their mean age was 59.6 (31-78) years. Among them, 97 patients (63.0%) underwent Whipple's procedure, 45 (29.2%) pylorus-preserving pancreaticoduodenectomy, 7 (4.5%) total pancreatectomy, and 5 (3.3%) hepatopancreaticoduodenectomy, respectively. Mean follow-up duration was 26.6 (0.4-108.5) months. The postoperative morbidity and mortality were 42.2% and 1.3%, respectively. Five-year survival rate was 32.8% and mean survival duration was 47.2 (39.1-55.3) months. Type of biliary drainage (percutaneous transhepatic biliary drainage), lymph node status (positive), and cellular differentiation (moderate or poor) were significant indicators for death in multivariate analysis of resectable dCC. CONCLUSIONS: Moderate or poor cellular differentiation and lymph node metastasis may be independent poor prognostic factors for resectable dCC.

Correlation of Ki-67, nm23-H1 and the VEGF Expression with the Clinicopathological Variables for Distant Recurrence after Curative Surgery for Carcinoma of the Ampulla of Vater

PURPOSE: Not a few patients show early distant recurrence after curative resection for carcinoma of the ampulla of Vater, and this recurrence is not just related to the clinicopathological factors. This study was performed to determine the correlation of the clinicopathological and biological characteristics with early distant recurrence after surgery for carcinoma of the ampulla of Vater. METHODS: Of the 158 patients who underwent curative resection for carcinoma of the ampulla of Vater at the Samsung Medical Center between December 1994 and August 2004, 38 patients (the recurrence group) with distant recurrence within a year after surgery and 32 patients (the non-recurrence group) without recurrence for more than 3 years after surgery were retrospectively analyzed. Evaluation of their clinicopathological characteristics and their immunohistochemical staining for Ki-67 antigen, nm23-H1 protein and vascular endothelial growth factor (VEGF) were carried out. RESULTS: Of the recurrence group, 24 patients (63.2%) had multiple recurrence sites and 10 (26.3%) were TNM stage I after surgery. The TNM stage was significantly advanced in the recurrence group. Both the Ki-67 labeling index (LI) (10.2% vs. 5.8%, respectively) and positive rate (50.0% vs.18.8%, respectively) according to the cut-off value of Ki-67 LI (i.e. 9%) were significantly higher in the recurrence group. The immunoreactivity for nm23-H1 protein and VEGF was not different between the two groups. Only lymph node metastasis was statistically significant on the multivariate analysis for early distant recurrence after surgery. CONCLUSION: The recurrence group showed an advanced TNM stage and increased Ki-67 LI. Lymph node metastasis was the single independent poor indicator for early distant recurrence after curative resection for carcinoma of the ampulla of Vater.
