ABSTRACT
Objective To study the risk factors of post-hepatectomy hepatic decompensation (PHD) in patients with hepatocellular carcinoma.MethodWe reviewed 562 patients with Child-Pugh A classification,who underwent partial hepatectomy for hepatocellular carcinoma at Zhongshan Hospital,Fudan University between July 1st 2007 to December 31st 2007,to study the risk factors of hepatic decompensation.ResultsPreoperative high total bilirubin (TB) and low prealbumin (PA) were independent risk factors of PHD by logistic multivariate analysis ROC analysis revealed the cut-offs of preoperative PA predicting PHD were 0.14 g/L (sensitivity 41.4％; specificity 83.1％).The incidence of PHD was 16.0％ when TB≥20.4 μmol/L and PA＜0.14 g/L(OR=7.276,P=0.002).ConclusionThe Child-Pugh A patients recovered well when the preoperative liver function was as follows:TB＜20.4 μmol/L and PA≥0.14 g/L.
ABSTRACT
Objective To summarize the clinical experienee in surgical treatment for hepatocellular carcinoma (HCC). Methods The clinical data of 7566 HCC patients who had been admitted to Research Institute of Liver Cancer of Fudan University from January 1988 to Deeember 2007 were retrospectively analyzed. The overall survival and recurrence free survival (RFS) rates were eaeulated with Kaplan-Meier survival curve. All the data were analyzed using Log-rank test and Cox regression model. Results The 3-, 5-, 10-year overall survival and RFS rates of 7164 patients with HCC resection were 56.29%, 41.76%, 26.70%, and 63.92%, 56.12%, 42.97%, respectively, and the perioperative mortality was 1.54%. The 5- and 10-year overall survival rates of patients with small HCC (diameter<5 era) were 58.20% and 38.47%, which were significantly higher than 31.42% and 20.43% of patients with large HCC (diameter >5 cm) (X2 =535. 568, P <0.01). The 5-year overall survival rotes of HCC patients with resection after down-staging (n = 110), re-resection after recurrence (n = 515), and tumor thrombus in portal vein (n = 168) were 51.26%, 67.28% and 26.81%, respectively; nd the 5-year DFS rotes were 77.44%, 13.01% (calculated from the first operation) and 34.90%, respectively. The 3- and 5-year overall survival and DFS rates of 402 patients who had undergone liver transplantation were 60.81%, 55.63% and 64.47%, 58.52%. The independent prognostic factors influencing the overall survival and DFS rates were the size, number and differentiation of HCC and intrahepatic vessel invasion (X2 = 200.539, 27. 536, 96.964,216. 156, P <0.01). Conclusions Early screening, improved safety of surgery, combined therapy and breakthrough in the reseaeh of preventing HCC metastasis and reeurrenee will significantly improve the treatment outcome of HCC.
ABSTRACT
Objective To investigate the effects of preventive chemotherapy for hepatocellular carcinoma (HCC) exceeding Milan criteria after liver transplantation. Methods The clinical data of 243 patients who had undergone orthotopic liver transplantation for HCC exceeding Milan criteria from April 2001 to July 2007 were retrospectively analyzed. Of all patients, 162 received preventive chemotherapy after transplantation. Results The 1- and 3-year survival rates and disease-free survival rates were not statistically different between patients who had received chemotherapy (78.5%, 63.7% ; 76.8%, 52.5% ) and those without chemotherapy (56.6%, 39.1%; 69.3%, 64.7% ) (X2 = 3.084, 0.444, P > 0.05). Cox regression analysis demonstrated that postoperative chemotherapy was not an independent factor affecting the survival rates of HCC patients without vascular invasion, but an independent factor affecting the survival rates of HCC patients with vascular invasion. Conclusions Early preventive chemotherapy could obviously increase the survival rate and delay the tumor recurrence of patients with HCC exceeding Milan criteria, especially for HCC patients with vascular invasion.
ABSTRACT
Objective To investigate the diagnosis and treatment of hepatic metastasis from gastrointestinal stromal turnor(GIST).Methods The clinical data of 16 patients with GIST who had been admitted to our hospitalfrom December 1993 to May 2007 were retrospectively analyzed.Results Of all patients,14 underwent radical resection and 2 underwent palliative operation.Two patients with palliative operation and 3 with radical resection were administered with imatinib postoperatively. All patients were followed up for 3-161 months,and GIST metastasis and invasion was observed in 8 of the 14 patients who received radical resection.Of the 7 patients with hepatic metastasis.3 were treated with hepatic artery chemoembolization,1 was administered with imatinib,2 received reoperation and 1 did not receive any treatment. Reoperation was carried out on 1 patient who had abdominal wall metastasis.The 1-and 3-year survival rates of the 16 patients were 92%and 74%,respectively.Conclusions The recurrence rate of GIST after hepatectomy is high.Complete surgical resection is the best curative treatment for hepatic metastasis from GIST and GIST recurrence.The combination of surgical resection and imatinib administration may help to improve the prognosis of patients with hepatic metastasis from GIST.
ABSTRACT
Objective To evaluate salvage liver transplantation(LT)for postoperative tumor recurrence or liver dysfunction in patients of hepatocellular carcinoma(HCC).Methods From April 2001 to March 2006,97 HCC patients with the tumor within Milan Criteria underwent LT as the primary treatment(71 cases)and salvage LT because of after resection tumor recurrence(n=20)or postoperative liver dysfunction(n=6).Perioperative and postoperative parameters and long-term survival were compared between the groups of primary LT and salvage LT.Results The mean age(50.0 years vs.49.7 years),gender,and etiology of liver disease(hepatitis B/C/nonviral)were comparable between the two groups.In the salvage LT group.the mean time between liver resection and LT was 2.50 years.Clinical characteristics such as tumor number(1.37 vs.1.50),operative time(7.92 hours vs.8.56 hours),blood loss (1981.69 ml vs.2626.92 ml)and transfusion(1981.69 ml vs.2626.92 ml)were not statistically different (P＞0.05)between the two groups.The size of largest tumor was significantly different between salvage LT group and the primary LT group(2.81 cm vs.2.05 cm)(t=2.298,P=0.028).By a median follow up of 14.63 months,overall survival after liver transplantation was not different between the 2 groups(X2=0.003.P=0.959).Conclusion In selected patients,liver resection prior to transplantation does not increase the morbidity or impair long.term survival following LT.Therefore.1iver resection prior to transplantation can be integrated with the treatment strategy for HCC.
ABSTRACT
Objective To study the early diagnosis and management of the patients with acute respiratory distress syndrome (ARDS) caused by cytomegalovirus (CMV) pneumonia after liver transplantation.Methods The clinical data of 8 patients with ARDS caused by CMV pneumonia after liver transplantation in our hospital from April 2001 to May 2004 was retrospectively analyzed. All cases were treated with intravenous infusion of gancyclovir, reduced dosage of cyclosporine A or tacrolimus to 1/3~1/2 of baseline and withdrawal of MMF and prednisone. The patients were subjected to breathing machine assist ventilation and nutrition supply.Results Five patients recovered and 3 died. No one developed acute rejection. Conclusions The key of early diagnosis lies in combining chest X-ray or CT scan with clinical presentation. Administration with anti-viral drugs, adjustment of immunosuppressive agents, management with breathing machine assist ventilation and effective nutrition supply are important for the treatment of patients with ARDS caused by CMV pneumonia after liver transplantation.
ABSTRACT
5 cm and portal vein tumor thrombus significantly affect the tumor-free survival of the patients.
ABSTRACT
Objective To evaluate the diagnosis and treatment of focal nodular!hyperplasia of the liver (FNH). Methods Retrospective analysis was made on 60 FNH cases in terms of clinical findings, images, pathologic examination and surgical treatment. Results Of the 60 FNH patients in our hospital from 1993 to 2003, 41 were male and 19 female. The average age was 37 year′s old. Fifty-five cases had single focus, the other five were of multiple lesion, with tumor diameter 10cm in one. Correct preoperative diagnosis was made in 33 cases (55%). The correct diagnostic rate of BUS, CT and MRI was 33.3%, 58.3% and 72.0%, respectively. All 60 cases underwent operation with an uneventful recovery and without recurrence at follow-up. ConclusionsCT and MRI are mandatory for the diagnosis of FNH. Definite preoperative diagnosis is usually difficult even in cases of typical type of FNH. Surgical resection is the treatment of choice when a patient becomes symptomatic or when malignancy could not be excluded.
