The present study shows that GB polyps >/=10 mm in size in patients aged >/=57 years are the independent factors predicting malignancy of the GB.

Initial CA 19-9, American Joint Committee on Cancer stage, and treatment modality were independent prognostic factors of OS, and the patients who received chemotherapy or CCRT showed better survival than those who received supportive care only.

Protein expression of MEN1 and DAXX/ATRX can be prognostic markers for PanNETs. Further investigation in genetic alterations of PanNETs may give us insights understanding the behavior of PanNETs.

The aberrantly methylated NPTX2 gene may help to distinguish between chronic pancreatitis and pancreatic cancer with conventional diagnostic tools and could become a valuable diagnostic marker.

OBJECTIVES: Endoscopic ultrasonography-guided ethanol ablation therapy for pancreatic cystic lesions is a minimally invasive treatment but still is an experimental therapy. The aims were to investigate the safety and efficacy of endoscopic ultrasonography-guided ethanol ablation therapy. METHODS: The inclusion criteria were the following: clinically indeterminate pancreatic cystic lesions in radiologic imaging studies, 2 to 5 cm unilocular or oligolocular cysts without communication to main panc

Low-dose prophylactic treatment with ulinastatin immediately after ERCP did not show a beneficial influence on the incidence of post-ERCP pancreatitis and hyperamylasemia in high-risk patients.

Magnetic resonance imaging as an additional diagnostic modality to MDCT increased the accuracy, sensitivity, and specificity, as well in terms of predicting neoplastic cysts.

BACKGROUND: Life expectancy of pancreatic ductal adenocarcinoma (PDAC) patients is usually short and selection of the most appropriate treatment is crucial. The aim of this study was to investigate the usefulness of serum CA 19-9 as a surrogate marker under no impress excluding other factors affecting CA 19-9 level other than tumor itself. METHODS: We recruited 1,446 patients with PDACs and patients with Lewis antigen both negative or obstructive jaundice were excluded to eliminate the false eff

BACKGROUND AND AIM: Abdominal wall hernia is a common feature of decompensated liver cirrhosis and frequently causes life-threatening complications or severe pain. However, there have been no data reported on postoperative mortality, hepatic functional deterioration and recurrence rate according to Child-Turcotte-Pugh (CTP) class and to the presence of refractory ascites. METHODS: The study population comprised 53 liver cirrhosis patients who underwent hernia repair operation. Comparisons were m

The quantitative analysis of NPTX2 hypermethylation may play a role in making highly sensitive and less invasive diagnosis of pancreatic cancer. Therefore, NPTX2 hypermethylation could be a promising molecular diagnostic marker.

Circulating tumor cells (CTCs) are useful biomarkers of many solid tumors, but are infrequently detected in early stage pancreatic ductal adenocarcinomas (PDACs). The first drainage of pancreatic venous blood flow come to portal vein and pass through the liver, and they finally go out for peripheral blood. We thought that comparing CTCs from portal vein and peripheral blood could enable us to understand the clinical meaning of CTCs from each different site in PDACs. Therefore, we aimed to determ

Solid pseudopapillary tumors are low-grade tumors that have a generally good prognosis. However, the clinical development and malignancy potential of SPTs are neither fully understood nor predictable, even with histologically benign tumors. Further investigations in tumor biology, along with long-term patient follow-up, may provide insight into the disease process and clinical development of SPTs.

Abstract Background Intratumoral heterogeneity (ITH) and tumor microenvironment (TME) of pancreatic ductal adenocarcinoma (PDAC) play important roles in tumor evolution and patient outcomes. However, the precise characterization of diverse cell populations and their crosstalk associated with PDAC progression and metastasis is still challenging. Methods We performed single-cell RNA sequencing (scRNA-seq) of treatment-naïve primary PDAC samples with and without paired liver metastasis samples to u

Patients with locally advanced pancreatic cancer who received gemcitabine chemotherapy or 5-FU-based CCRT showed better survival than those who received supportive care only. Gemcitabine chemotherapy and 5-FU-based CCRT showed similar survival advantages.
