The underlying mechanisms between cancer stem cells (CSC) and epithelial-mesenchymal transition (EMT) in pancreatic cancer (PC) remain unclear. In this study, we identified TGIF2 as a target gene of CSC using sncRNA and machine learning. TGIF2 is closely related to the expression of SOX2, EGFR, and E-cadherin, indicating poor prognosis.

Despite its effectiveness, this regimen is often marred by side effects such as anemia, neuropathy, fatigue, nausea, and malnutrition, which significantly affect patients' tolerance to the treatment. Some studies have shown that vitamin C could potentially augment chemotherapy's tolerability, notably by boosting iron absorption, ameliorating anemia, and relieving pain and numbness in hands and feet.

Ferroptosis is a type of programmed cell death closely related to amino acid metabolism. Pancreatic cancer cells have a strong dependence on glutamine, which serves as a carbon and nitrogen substrate to sustain rapid growth. Glutamine also aids in self-protection mechanisms.

It is important to establish aggressive subgroups of pNENs and identify potential therapeutic targets. Patients with pNEN (322 cases) were included to examine the association between glycosylation biomarkers and clinical/pathological traits.
View Article and Find Full Text PDFBackground: Carbohydrate antigen 19-9 (CA19-9) is the most widely used biomarker for pancreatic cancer. Since CA19-9 closely correlates with patient outcome and tumor stage in pancreatic cancer, the deciphering of CA19-9 biosynthesis provides a potential clue for treatment.
Methods: Concentration of amino acids was detected by ultrahigh-performance liquid chromatography tandem mass spectrometry.
Background: Diabetes mellitus is a prevalent comorbidity in pancreatic cancer. Previous studies have mainly concentrated on the association between diabetes and pancreatic cancer outcomes. However, research on the impact of hyperglycemia on the prognosis of patients with advanced pancreatic cancer is limited.
View Article and Find Full Text PDFBackground: Intraductal papillary mucinous neoplasms (IPMNs) are characterized by their abundant mucin production and malignant potential. IPMNs of the pancreas are mainly managed according to their radiographic indications, but this approach lacks accuracy with regard to IPMN grading. Therefore, serological biomarkers such as CA19-9 and CA125 (MUC16) should be employed to assist in predicting the invasiveness of IPMNs.
View Article and Find Full Text PDFBackground: Pancreatic ductal adenocarcinoma (PDAC) displays a typical mucin expression pattern which is characterized by MUC1 positive, MUC2 negative, and MUC5AC positive. More and more evidences show that mucins are involved in the development of pancreatic diseases. However, the relationship between mucin expression and prognosis of PDAC patients has been controversial in the past decades; therefore, we aim to figure out the association of mucin expression with survival in PDAC patients who underwent radical resection.

Methods: A retrospective study including 335 patients with pathologically confirmed pNENs was conducted. A baseline fasting blood glucose concentration ≥5.
Pancreatic ductal adenocarcinoma (PDAC) is a well-known lethal and heterogeneous disease. Apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like (APOBEC) is an important mutagenic driver that has seldom been investigated in PDAC. Therefore, this study investigated the significance of APOBEC3C in PDAC.

Methods: The data from a retrospective collected database from 2010 to 2019 with 699 patients who had MDCT scan predicted resectable mass in pancreatic body and tail and were pathological confirmed as adenocarcinoma after surgery. Receiver operating characteristic (ROC) curve was plotted for serum CA19-9, CA125, CEA and tumor size measured by MDCT.
Background: Glutamine-fructose-6-phosphate transaminase 1 (GFPT1) is the first rate-limiting enzyme of the hexosamine biosynthesis pathway (HBP), which plays a pivotal role in the progression of pancreatic ductal adenocarcinoma (PDAC). Therefore, we investigated the prognostic significance of GFPT1 expression in patients with resectable PDAC.
Methods: We analyzed public datasets to compare GFPT1 expression in tumor tissues and normal/adjacent pancreatic tissues.
Background: The fibrinogen/albumin ratio (FAR) has been widely reported to be a possible biomarker for predicting prognosis in several types of tumors, but the prognostic value of the FAR in pancreatic neuroendocrine neoplasms (Pan-NENs) has not been systematically studied.
Patients And Methods: In total, 324 patients with Pan-NENs were recruited. The patients were divided into 2 subgroups according to the FAR cutoff value, and clinicopathological characteristics of the 2 subgroups were compared.
Mucinous cystic neoplasms (MCNs) of the pancreas have malignant potential. Carbohydrate antigen 125 (CA125) is a common widely used biomarker for cancers. However, the role of CA125 in predicting the malignant change of MCNs is currently unidentified.

Pancreatic ductal adenocarcinoma (PDAC) is a malignancy characterized by a poor prognosis and high mortality rate. Genetic mutations and altered molecular pathways serve as targets in precise therapy. Using next-generation sequencing (NGS), these aberrant alterations can be identified and used to develop strategies that will selectively kill cancerous cells in patients with PDAC.
View Article and Find Full Text PDFBackground: Hyperglycaemia has been indicated as a pro-tumoural factor; however, the prognostic role of diabetes mellitus (DM) in pancreatic neuroendocrine tumours (panNETs) remains ambiguous, partly due to the effects of anti-diabetic drugs. We hypothesise that the blood sugar level per se affects the outcome of panNETs, and thus, we investigated the prognostic significance of the fasting blood glucose (FBG) level in resected panNET patients with no pre-existing DM.
Methods: A retrospective cohort study comprising 201 patients with radically resected non-functional panNETs was conducted.
Purpose: Pancreatic neuroendocrine tumours (panNETs) are rare tumours of pancreas. Lymphocyte subsets in the peripheral blood are reported to reflect tumour prognosis and progression. The objective of the study is to investigate the hypotheses that the levels of peripheral lymphocytes may reflect tumour progression and may predict the prognosis of pancreatic neuroendocrine tumours (panNETs).

Carbohydrate antigen 19-9 (CA19-9) is the best validated biomarker and an indicator of aberrant glycosylation in pancreatic cancer. CA19-9 functions as a biomarker, predictor, and promoter in pancreatic cancer. As a biomarker, the sensitivity is approximately 80%, and the major challenges involve false positives in conditions of inflammation and nonpancreatic cancers and false negatives in Lewis-negative Individuals.
View Article and Find Full Text PDFPatients with distal (body/tail) pancreatic cancer have been found to present worse outcome than patients with head cancer, which is generally attributed to the great proportion of advanced stages for body/tail cancers upon detection. However, differences in prognosis between head and body/tail pancreatic cancers controlled by stage have not been analyzed in-depth. In this study, differences in prognosis between head and body/tail pancreatic cancers were examined using the Surveillance, Epidemiology, and End Results Program (SEER) (1973-2014 registry, 85,715 cases).

Methods: In this study, 299 patients with pNETs were recruited, and the clinicopathologic characteristics and prognosis of the diabetic and nondiabetic patients were compared. The association between metformin use and survival was assessed to examine whether metformin impacts the prognosis of pNETs patients.
Carbohydrate antigen 19‑9 (CA19‑9) is the most important biomarker for pancreatic cancer. Approximately 5‑10% of individuals are Lewis antigen negative with scarce secretion of CA19‑9 and fucosylation deficiency. However, the characteristics of Lewis‑negative pancreatic cancer are unidentified.
