RESUMO

Purpose To explore the relationship between the change of space anterior to right portal vein and the pathological staging in liver ifbrosis/cirrhosis. Materials and Methods Plain and contrast enhanced CT scan were performed in patients with biopsy proven liver ifbrosis/cirrhosis including S1 in 17 patients, S2 in 13 patients, S3 in 15 patients, S4 in 21 patients and cirrhosis in 22 patients. Twenty subjects were included as control group. The width of anterior space of right portal vein was measured on contrast enhanced CT and correlated with ifbrosis staging. The receiver operating characteristic curve was created for cirrhosis diagnosis. Results The width of anterior space of right portal vein enlarged in patients with S3 ifbrosis to cirrhosis (P<0.05 or P<0.01). It was signiifcantly bigger in group S4 compared to other groups (P<0.01). Spearman rank correlation analysis showed significant positive correlation between the width of anterior space and liver fibrosis staging (r=0.704, P<0.01). ROC curve analysis showed the area under curve (AUC) of 0.897 with the optimum width of ≥10 mm. Conclusion The change in the space anterior to the right portal vein is positively correlated with live ifbrosis staging. CT measurement helps early diagnose and assess the severity of liver ifbrosis and cirrhosis.

RESUMO

<p><b>OBJECTIVE</b>To study the different expressions of glypican-3 in lung squamous cell carcinoma and adenocarcinoma and explore the association of glypican-3 with the prognosis of the patients.</p><p><b>METHODS</b>Glypican-3 expression was detected immunohistochemically in the tumor tissues and adjacent tissues from 48 cases of lung squamous cell carcinoma and adenocarcinoma. Kaplan-Meier method and log-rank test were used for survival analysis of the patients.</p><p><b>RESULTS</b>Glypican-3 expression was detected in the tumor tissues in 29.2% (14/48) of the cases, but not in the adjacent tissues. Of the 22 patients with lung squamous cell carcinoma, 12 (54.5%) showed positive glypican-3 expression in the tumor tissue, a rate significantly higher than that in patients with lung adenocarcinoma [7.7% (2/26), P<0.01]. In all the glypican-3-positive cases, the tumor tissues showed stronger glypican-3 expression in cases with lymph node metastasis or poor tumor differentiation. Kaplan-Meier survival analysis did not indicate a significant correlation of glypican-3 expression with the prognosis of the lung cancer patients.</p><p><b>CONCLUSION</b>Patients with lung squamous cell carcinoma have higher glypican-3 expressions in the tumor tissues than those with lung adenocarcinoma, suggesting the value of glypican-3 protein as a potential marker to detect lung squamous cell carcinoma.</p>
