Filter by:More and more older adults are diagnosed with pancreatic ductal adenocarcinoma (PDAC), but the rate of surgical resection in patients with resectable tumour is still low. Clinical workers need to take more attention to oncologic care in this group. It's significant to explore potential predictors for impacting elderly patients chose to abandon surgical resection.
This study aimed to develop a novel Prognostic Oxidative Stress-Immune-Inflammatory Score (POSII Score) and introduce an innovative online calculator designed to predict long-term survival and assess the recurrence risk of gastric cancer (GC).
Occult peritoneal metastases (OPM) in patients with pancreatic ductal adenocarcinoma (PDAC) are frequently overlooked during imaging. We aimed to develop and validate a CT-based deep learning-based radiomics (DLR) model with clinical-radiological characteristics to identify OPM in patients with PDAC before treatment.
Endoscopic ultrasound-guided (EUS) tissue acquisition is the current standard of care for the diagnosis of pancreatic solid lesions but it is burdened by a non-negligible risk of non-diagnostic or inconclusive results. Ex-vivo fluorescence confocal laser microscopy (FCM) with MAVIG VivaScope® 2500M-G4 could allow real time assessment of adequacy and diagnosis of the sample.
To explore the potential utility of 18F-FAPI-04 PET/CT for pathologic response evaluation to systemic treatment in PDAC
Our study is a case report of one of the rarest risk factor, Peutz-Jeghers syndrome, of small bowel malignancy detected in a patient with poorly differentiated adenocarcinoma of small bowel(jejunum)
In this clinical study, investigators explore the efficacy and safety of a combination therapy regimen with antiangiogenic agent (apatinib), ICI (tislelizumab), and chemotherapy (capecitabine+ Oxaliplatin, XELOX) as first-line treatment for HER2-negative, advanced G/GEJ cancer patients with signet ring cell carcinoma or peritoneal metastasis.
The goal of this interventional study was to evaluate the synergistic effect of symbiotics (a combination of probiotics and prebiotics) compared to probiotics alone in terms of their impact on anti-tumor immunomodulation in patients with pancreatic ductal adenocarcinoma (PDAC). The study also aimed to assess the effects of these interventions on postoperative complications and outcomes. In the study, a probiotic agent (Nowfoods, USA), containing ten strains of bacteria with a total dosage of 25 billion colony-forming units (CFU) was administered. This probiotic regimen involved taking two capsules once daily, starting two weeks before the surgery and continuing for one month after the surgery. For the synbiotic group, in addition to the probiotic agent, two capsules per day of inulin supplement (HERBAMAMA, USA) were also taken. The study included three groups: the synbiotics group, the probiotics group, and the placebo group. The researchers compared the pathological status of immune cell infiltration (specifically CD8 cells) and interferon-gamma expression, as well as the levels of interleukins 10, 6, and 10 in the participants' serum. Four blood samples were collected from each participant: one taken 14 days before the surgery, one on the surgery date, one two weeks after the surgery, and one 30 days after the surgery. The main research question addressed by the study was whether there was a significant difference in the immunomodulatory effect and postoperative complications between the synbiotics group and the probiotics group. The placebo group likely served as a control to compare the effects of the interventions against no intervention.
Pancreatic ductal adenocarcinoma (PDAC) can be divided into pancreatic head cancer (PHC) and pancreatic body/tail cancer (PBTC) according to the anatomical position of tumors. There is increasing evidence that tumors at different sites exhibit different genetic or molecular features and clinical manifestations, and can affect the survival and outcomes of PDAC patients. Studies have shown that the prognosis of PBTC is worse than that of PHC, which is partly attributed to the relatively late clinical presentation of PBTC patients and the lack of overt symptoms such as obstructive jaundice, which is common in PHC. However, it has also been shown that the worse survival of PBTC compared to PHC is not related to the disease stage. Previous studies have investigated the molecular differences between PHC and PBTC and found that the frequency of SMAD4 mutation in PBTC was significantly higher than that in PHC at early stages (I-II). In the late stage (III-IV), PBTC had higher mutation frequency of Kirsten rat sarcoma viral oncogene homolog (KRAS) and mitogen-activated protein kinase (MAPK) pathway, but lower frequency of genomic alterations which can be targeted by drugs. The above genetic and molecular differences may be related to the clinical differences between PHC and PBTC. However, the differences in microbial composition and metabolism between PHC and PBTC have not been fully studied and discussed, and their relationship with clinical manifestations and prognosis is also unclear. In this study, the investigators aimed to analyze the microbial and metabolic differences between PHC and PBTC through 16S ribosomal ribonucleic acid (rRNA) sequencing and untargeted metabolome analysis to further explore the etiology and pathogenesis of PDAC at different anatomical positions.
The goal of this observational study is to learn about in small bowel adenocarcinoma patients. The main question it aims to answer is the association between tumor size and prognosis in patients with small bowel adenocarcinoma. Participants will be compared for the relationship between tumor size and prognosis.
