METHODS:Twenty-four patients with metastatic or locally advanced HCC in a normal or a fibrotic liver were given systemic chemotherapy(epirubicin,cis- platin and 5-fluorouracil or epirubicin,cisplatin and capecitabine regimens).Tumor response,time to pro- gression,survival,and toxicity were evaluated. RESULTS:There were 7 women and 17 men,mean age 54±10 years;18 patients had a normal liver and 6 had a fibrotic liver(F1/F2 on biopsy).Mean tumor size was 14 cm,5 patients had portal vein thrombosis and 7 had metastasis.Patients received a median of 4 chemotherapy sessions.Overall tolerance was good. There were 5 partial responses(objective response rate =22%),and tumor control rate was 52%.Second line surgical resection was possible in two patients.Median survival was 11 mo,and 1-and 2-year overall survival rates were 50%±10%and 32%±11%,respectively. CONCLUSION:In patients with HCC in a non-cirrhotic liver,chemotherapy was well tolerated and associated with an objective response rate of 22%,including two patients who underwent secondary surgical resection.展开更多

One organ from each pair was grown in control media and was used as the internal control for the experimental contralateral organ. In some experiments, organs were treated with ASA for 48 h and then transferred either to control media alone or control media containing 10 μmol/L prostaglandin E2 （PGE2） for a further 5 d. Fetal kidneys were additionally obtained from prostaglandin synthase 2 homozygous null or heterozygous （PTGS2-/- and PTGS2-/＋） embryos and grown in culture. Kidney cross-sectional area was used to determine treatment effects on kidney growth. Whole-mount labelling to fluorescently detect laminin enabled crude determination of epithelial branching using confocal microscopy.RESULTSIncreasing ASA concentration （0.1, 0.2 and 0.4 mg/mL） significantly inhibited metanephric growth （P 〈 0.05）. After 7 d of culture, exposure to 0.2 mg/mL and 0.4 mg/mL reduced organ size to 53% and 23% of control organ size respectively （ P 〈 0.01）. Addition of 10 μmol/L PGE2 to culture media after exposure to 0.2 mg/mL ASA for 48 h resulted in a return of growth area to control levels. Application of control media alone after cessation of ASA exposure showed no benefit on kidney growth. Despite the apparent recovery of growth area with 10 μmol/L PGE2, no obvious renal tubular structures were formed. The number of epithelial tips generated after 48 h exposure to ASA was reduced by 40% （0.2 mg/mL; P 〈 0.05） and 47% （0.4 mg/mL; P 〈 0.01）. Finally, growth of PTGS2-/- and PTGS2＋/- kidneys in organ culture showed no differences, indicating that PTGS2 derived PGE2 may at best have a minor role.CONCLUSIONASA reduces early renal growth and development but the role of prostaglandins in this may be minor.展开更多
