Measuring PDGFA, bFGF, and HIF1a expression may contribute to a better understanding of the prognosis of patients with pancreatic cancer and may even play a crucial role for the distribution of patients to multimodal therapeutic regimens. Larger studies including patients treated with actual chemotherapeutics seem to be warranted.
Heparanase seems to be significantly associated with lymph node metastasis (p = 0.025) as well as dedifferentiation (p = 0.042). We assume that HPSE plays a crucial role for the aggressiveness of pancreatic cancer. Larger studies including more patients seem to be warranted.
The purpose of the present study was to characterize histopathological lesions in primary biliary cirrhosis (PBC) and to assess the relationship between histopathological lesions and biochemistry. Liver biopsies of 252 patients with PBC were investigated. A laboratory database was established. Histopathological characterization was performed. Relationships between detailed histopathological features and biochemistry were calculated statistically. Combining the data, a PBC group, consisting of an anti-mitochondrial antibody (AMA)-positive and -negative subgroup, and an overlap group were defined, with a female preponderance of >90% and higher activity of aspartate aminotransferase (AST) in the overlap group. Histopathological changes were characteristic in >80%. Periductal concentric fibrosis, lobular granuloma formation and steatosis were frequently remarkable. Correlations were found between alanine aminotransferase activity and modified hepatitis activity index in the overlap group and the AMA-positive group. A positive significant relationship was demonstrated between mean AST activity and portal fibrosis for the AMA-positive group. A highly significant positive link was seen between mean concentration of bilirubin and stage of fibrosis. Biochemistry reflects only in part the degree of severity of histopathological lesions in PBC. Histopathology indicates comorbidity in a high percentage of patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
