Epidemiological trends for functional pancreatic neuroendocrine tumors: A study combining multiple imputation with age adjustment.

Purpose: The purpose of this study was to examine trends in the incidence and incidence-based (IB) mortality of functional pancreatic neuroendocrine tumors(F-PNETs), and to identify factors associated with survival times.

Methods: Data were obtained from the Surveillance, Epidemiology, and End Results database from 2000 to 2017. Trends in the age-adjusted incidence of F-PNETs and IB mortality were examined using the Joinpoint Regression Program.

Pancreatic adenosquamous carcinoma: A population level analysis of epidemiological trends and prognosis.

Background: The incidence and mortality of pancreatic adenosquamous carcinoma (PASC) have received little attention. The goal of our study was to explore the overall epidemiological trend of PASC at the population level.

Methods: The Surveillance, Epidemiology, and End Results database was used to collect the incidence, incidence-based (IB) mortality, and patient details for PASC from 2000 to 2017.

Validation of a supplementary condition of eighth AJCC staging system for stage II hepatocellular carcinoma.

Introduction: The eighth American Joint Committee on Cancer (AJCC) staging system was flawed regarding the prognosis of stage II hepatocellular carcinoma (HCC). The aims of this study were to reveal the defect and make updates.

Methods: Clinical and survival data of HCC patients from the Surveillance, Epidemiology, and End Results database were used.

Validation of the Prognostic Role for Surgical Treatment in Stage II Intrahepatic Cholangiocarcinoma: A SEER Population-Based Study.

Background: This study aimed to determine the role of surgical treatment in patients with stage II intrahepatic cholangiocarcinoma (iCCA). Methods: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We divided stage II iCCAs into solitary tumors with vascular invasion (T2sN0M0) and multiple tumors with/without vascular invasion (T2mN0M0) according to the criteria of AJCC v.

Robotic versus open extended cholecystectomy for T1a-T3 gallbladder cancer: A matched comparison.

Background: The feasibility and safety of robotic extended cholecystectomy (REC) are still uncertain. This study was performed to compare the short- and long-term outcomes of REC with those of open extended cholecystectomy (OEC) for T1a-T3 gallbladder cancer.

Methods: From January 2015 to April 2022, 28 patients underwent REC in our center.

Metabolic signatures of hepatolithiasis using ultra-high performance liquid chromatography-tandem mass spectrometry.

Background & Aims: A metabolomic study of hepatolithiasis has yet to be performed. The purpose of the present study was to characterize the metabolite profile and identify potential biomarkers of hepatolithiasis using a metabolomic approach.

Methods: We comprehensively analyzed the serum metabolites from 30 patients with hepatolithiasis and 20 healthy individuals using ultra-high performance liquid chromatography-tandem mass spectrometry operated in negative and positive ionization modes.

Choice of operative method for pancreaticojejunostomy and a multivariable study of pancreatic leakage in pancreaticoduodenectomy.

Background: As one of the major abdominal operations, pancreaticoduodenectomy (PD) involves many organs. The operation is complex, and the scope of the operation is large, which can cause significant trauma in patients. The operation has a high rate of complications.

Expression of caspase-3 and hypoxia inducible factor 1α in hepatocellular carcinoma complicated by hemorrhage and necrosis.

Background: Hepatocellular carcinoma (HCC) is a malignant tumor that occurs in the liver. Its onset is latent, and it shows high heterogeneity and can readily experience intrahepatic metastasis or systemic metastasis, which seriously affects patients' quality of life. Numerous studies have shown that hypoxia inducible factor1α (HIF-1α) plays a significant role in the occurrence and development of tumors, as it promotes the formation of intratumoral vessels and plays a key role in their metastasis and invasion.
