Objective: To elucidate the expression of the bcl-2 gene in association with both biological characteristics of human primary pancreatic carcinoma and patient's prognosis.
Methods: The s-p immunohistochemistry assay was used to detect the expression of the bcl-2 gene on paraffin-embedded sections from 97 cases of primary pancreatic carcinoma, 32 cases of pancreatitis, and 21 cases of normal pancreas.
Results: Among the 97 cases of pancreatic carcinoma, 70 (72.2%) showed positive staining for the bcl-2 protein. In the 32 cases of pancreatitis, 3 (9.4%) showed positive immunostaining for the bcl-2, and in the normal pancreas cases, 1 (4.8%) showed positive immunostaining for the bcl-2. However, the positive staining rates of the bcl-2 protein were lower in tumor tissue from the patients with metastases and tumor-node-metastasis (TNM) stages III, IV than in those from those with non-metastases, well differentiation, non-invasion and TNM stages I, II. The patients with positive immunostaining of bcl-2 have a longer postoperative survival than those with negative staining.
Conclusions: Pancreatic carcinoma expressed a high positivity for bcl-2. Findings suggested that the overexpression of bcl-2 is related to the carcinogenesis and progression of human pancreatic carcinoma. Bcl-2 might be one of the parameters in terms of biological characteristics and good prognosis in patients with pancreatic carcinoma.

This work researched the influence and mechanism of CD155 on hepatocellular carcinoma advancement. CD155 expression and its effect on survival of hepatocellular carcinoma patients were analyzed based on the GEPIA2 database. String software predicted the interacting between CD155 and CD96, which was further verified by co-immunoprecipitation experiment.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. The roles of the transcription factor special AT-rich binding protein-2 (SATB2) and β-catenin in PDAC have been a subject of controversy. We aimed to assess the diagnostic and prognostic impact of SATB2 and β-catenin in PDAC.

Serum levels of the tumor marker CA 19-9 are widely utilized in the diagnosis and monitoring pancreatic and biliary malignancies. However, serum levels of CA 19-9 have also been reportedly elevated in non-malignant conditions. Here, we present the rare case of a 65-year-old woman with a history of gallbladder malignancy who was found to have a new hepatic lesion on surveillance CT with an associated elevation in CA 19-9 to 5,866 U/mL.
