2.Current status and prospect of liver transplantation for hepatocellular carcinoma.
Acta Academiae Medicinae Sinicae 2005;27(4):427-430
The indications, effectiveness, and other relevant problems of the orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) are still under controversy in our country. This article collects and analyzes resent published literatures as well as the clinical data of 112 patients who underwent OLT for HCC in our hospital, and tries to investigate the staging system of HCC, liver allocation policy for OLT, expanded criteria for OLT in HCC, tumor management when awaiting transplantation, prognostic factors of recurrence, and principles to make a choice between resection and transplantation in patients with HCC. It is most important to establish a staging system and transplantation indications for liver transplantation of HCC in China.

OBJECTIVETo explore the effects of overexpression of human tissue inhibitors of metalloproteinase-1 (hTIMP-1) on proliferation, invasion, metastasis, angiogenesis, and apoptosis in human hepatocellular carcinoma (HCC) cells in vitro and in vivo.
METHODSRecombinant adenoviral vector containing hTIMP-1 (AdhTIMP-1) was constructed previously. HepG2 cells were infected by AdhTIMP-1 and the changes of cell proliferation and invasion were detected in vitro. The anticancer activity of AdhTIMP-1 was evaluated in BAL B/c mice bearing HCC. Tumor volume and pulmonary metastases were observed. The mechanisms underlying the antitumor effect in vivo were investigated based on detection of microvessel density and apoptosis in tumor tissues.
RESULTSThe resultant AdhTIMP-1 was successfully constructed and the expression of hTIMP-1 was detected by Western blot and RT-PCR. AdTIMP-1 could effectively infect HepG2 cells and significantly inhibit the proliferative activity and invasive ability of the tumor cells. Compared with the controls, pre-infection of HepG2 cells by AdhTIMP-1 resulted in a significant inhibition of tumor formation by 75. 8%. A single local injection of AdhTIMP-1 into pre-established tumors significantly reduced the tumor growth rate by 45.4%, tumor-associated angiogenesis index by 47.8%, lung metastases by 70.4%, and showed a 3-fold increase of apoptotic tumor cells.
CONCLUSIONOur data indicated that AdhTIMP-1 can significantly attenuate tumor proliferation and invasion, reduce metastasis, inhibit angiogenesis, and induce apoptosis in HCC-bearing mice and may pave the way for further liver cancer gene therapy.

OBJECTIVETo analyze the complication rate and survival rate of the patients whose graft-recipient weight ratio (GRWR) less than 0.8% following living donor liver transplantation (LDLT).
METHODSThere were 92 consecutive LDLT patients from January 2001 to December 2007 in West China Hospital, Sichuan University. There were 85 males and 7 females aged from 18 to 65 years old (averaged, 42 years old) and among which 89 patients were involved in the study. There were 15 patients whose GRWR less than 0.8% (group 1), while other 74 recipients were in group 2. Comparing the two groups' complication rates and survival rates and finding out the potential influencing factor of small-size-graft recipients' survival rate.
RESULTSThe survival rates of group 1 and group 2 were 73.3% (11/15) and 71.6% (53/74), respectively. The grade II-V complication rates of group 1 and group 2 were 46.7% (7/15) and 48.6% (36/74), respectively. There were no difference in survival rates (chi(2) = 0.058, P = 0.811) and complication rates (chi(2) = 0.000, P = 1.000) between the two groups. Ascites volume of group 1 and group 2 were (1532 +/- 322) ml and (1466 +/- 110) ml, respectively (t = 0.234, P = 0.815). The condition of the graft's middle hepatic vein had significant influence on small-size-liver recipients' survival rates (chi(2) = 6.821, P = 0.009).
CONCLUSIONSGRWR < 0.8% is not the limitation of the living donor liver transplantation but the outflow tract of the graft must be unobstructed.

OBJECTIVETo discuss the safety line to avoid the post-hepatectomy hepatic insufficiency by combining indocyanine green test by pulse dye-densitometry (PDD-ICG) and standard remnant liver volume (SRLV).
METHODSSeventy-five hepatic cancer patients undergone hepatectomy from March 2007 to February 2008 were included. According to the liver function decompensatory grades after operation, the relationship between ICG retention rate at 15 min (ICGR15) and standard remnant liver volume by linear regression were analyzed.
RESULTSThere were 60 cases with slight hepatic insufficiency, 12 cases with moderate hepatic insufficiency, and 3 cases with severe hepatic insufficiency. There were no difference in age [(50 +/- 13) years old and (53 +/- 9) years old], prothrombin time [(13.6 +/- 1.0) s and (13.5 +/- 1.0) s], international normalized ratio (1.09 +/- 0.10 and 1.06 +/- 0.10) between slight hepatic insufficiency group and moderate and severe hepatic insufficiency group (P > 0.05). And there were difference in K value (0.20 +/- 0.04 and 0.17 +/- 0.03), ICGR15 (6 +/- 4 and 9 +/- 4), SRLV [(545 +/- 93) ml and (398 +/- 82) ml] between two groups (P < 0.05). Compared ICG test and standard remnant liver volume of the patients with moderate hepatic insufficiency after operation, the liner relationship was found (R = 0.640, P = 0.025), and the regression equation was: standard remnant liver volume (ml/m(2)) = 1594.6 x ICGR15 + 265.
CONCLUSIONSPDD-ICG test and standard remnant liver volume are effective to estimate hepatic function reserve of patient undergone hepatectomy.

ObjectiveTo describe the modified (narrowed) gastric tube and two methods on the establishmentof enteral feeding pathway in esophagectomy.MethodsFrom July 2003 to April 2006,we made traditional gastric tube for patients underwent esophagectomy to substitute the dissected esophagus while from May 2006 to November 2009,we made modified gastric tube for the same purpose.From July 2003 to November 2009,enteral nutrition tubes for all these patients are placed intraoperatively by two different ways,which made early post-operative nutrition support possible for these patients.ResultsNo perioperative death occurred among the patients.The length of the modified gastric tube ensured the anastomosis by circular stapler at the apex thorax or in the bases of cervical region.No statistical differences were found between the two group in terms of survival rate.The intraoperative establishment of enteral nutrition pathway ensured the early enteral nutrition support after the operation.ConclusionThe utility of the modified gastric tube extends the length of gastric tube to make mechanical anastomose easier and safer; meanwhile,the intraoperative establishment of enteral nutrition pathway ensures the early enteral nutrition support after the operation.
