ABSTRACT

Objective:To clarify the indications and efficacy after simultaneous surgical treatment in gastric cancer patients with synchronous hepatic metastases (GCHM).Methods:A total of 21 GCHM patients who underwent D2 gastrectomy with R0 hepatic resection (11 cases) or non-R0 hepatic resection (10 cases) from March 2004 to April 2016 were analyzed retrospectively.The clinicopathological characteristics and survival were compared between the two groups.Results:Cumulative survival rate was improved in R0 hepatic resection group compared with non-R0 hepatic resection group:1-year (54.5% vs 48.0%),2-year(27.3% vs 0%),and 5-year(27.3% vs 0%,P=0.044).The median survival time in R0 hepatic resection group and non-R0 hepatic resection group were 16.2 and 5.9 months (P=0.008).Univariate analysis revealed that Bormann's classification (P=0.010) and state of regional lymph node (P=0.004) were significant predictive factors regarding cumulative survival rate.However,there was no significant prognostic factor (P=0.031) in multivariate analysis might partly owing to interaction among them and/or a small number of patients.Conclusion:Multidisciplinary treatments based on R0 hepatic resection combined with D2 gastrectomy could improve survival in selected GCHM patients.

ABSTRACT

Objective To investigate the expressions of cancerous inhibitor of protein phosphatase2A (CIP2A),phosphatidylinositol 3-kinase(PI3K),and survivin in pancreatic carcinomas and their clinical significance.Methods The expressions of CIP2A,PI3K,and survivin proteins were tested by immunohistochemistry in 64 cases of pancreatic carcinomas and adjacent paracancerous tissues.Results The positive rate of CIP2A in pancreatic carcinomas was significantly higher than adjacent paracancerous tissues (70.3% vs 5.6%,P <0.05).Significant difference was observed in the expression rate of PI3K between the patients with pancreatic carcinomas and paracancerous tissues (73.4% vs 8.3%,P <0.05).Significant difference was also observed in the expression rate of survivin between the patients with pancreatic carcinomas and paracancerous tissues (75.0% vs 2.8%,P <0.05).CIP2A,PI3K,and survivin were significantly differentially expressed in pancreatic carcinoma among different tumor differentiation,tumor node metastasis (TNM) stage,and neural invasion and lymph node metastasis (all P < 0.05).Spearman correlation analysis showed significantly positive correlation between the expressions of CIP2A and the others (PI3K and survivin) (both P <0.05),and between the expressions of PI3K and surviving (P <0.05).Conclusions CIP2A was involved in the development of pancreatic carcinomas and might activate the PI3K/Akt/survivin pathway.Our data identified CIP2A as a critical oncoprotein involved in cell proliferation,invasion,and metastasis.It could serve as a therapeutic target for pancreatic carcinomas.

ABSTRACT

Objective To investigate clinical result of hepatectomy and porta-enterostomy in the treatment of Bismuth type Ⅳ hilar cholangiocarcinoma.Methods Nine patients with Bismuth type Ⅳ hilar cholangiocarcinoma underwent accurate hilar resection(portal parecnchyma resection including about Ⅰ cm of the hilar part of the segments 5 and 4b and caudate lobe beyond the tumor),and the biliary drainage was reconstructed by Roux-en-Y portal parecnchyma-jejunum lpop anastomosis.None of the biliary radicals had to be ligated and all of them were drained into thus constructed"biliary pool".Results Hilar resection was successfully performed in all cases,and there was no postoperative mortality.Aspartate transaminase and alanine transaminase and serum bilirubin decreased evidently four weeks later.Three patients presented postoperative complications.One patient developed a transient anastomotic leakage,while one patient developed self-limiting hemobilia,wound infection occurred in one patient.All three patients were treated conservatively and recovered.The mean Karnofsky performance score was 86,with which they could carry on normal activity with minor symptoms of disease.Two patient died after 9 months and 17 months of extensive metastasis and intrahepatic metastasis respectively.The remaining seven patients are alive by a mean followup of 24.9 months after surgery without any signs of recurrence.Conclusions With accurate hilar resection and portal parecnchyma-to-enterostomy,the patients considerably benefit from the preservation of liver parenchyma and patent biliary drainage and radical resection.So the Hew technique prolongs the survival time and enhances the quality of life of the patients.
