Filter by:P-NENs are classified as functional (F-) or non-functional (NF-) depending on the presence or absence of a clinical hormonal hypersecretion syndrome. Moreover, the WHO 2017 classification of pNENs distinguishes between well-differentiated pancreatic neuroendocrine tumors (pNETs) and poorly differentiated pancreatic neuroendocrine carcinomas (pNECs). pNETs are then divided according to a grading scheme based on Ki67 index in pNETs-G1 (Ki67 index ≤3%) and pNETs-G2 (Ki67 index between 4% and 20%). pNECs are all G3, with a Ki67 index >20%. Endoscopic ultrasound with fine-needle biopsy (EUS-FNB) demonstrated safe and effective preoperative grading based on the Ki-67 proliferative index. However, downstaging rate is not neglectable, reaching 15% in a recent metanalysis. Moreover, recent whole-exome and whole genome sequencing studies revealed that the mutually exclusive inactivating mutations in death domain-associated protein (DAXX) and/or in α-thalassemia/mental retardation X-linked (ATRX) chromatin remodeling genes are associated with more aggressive disease. In a retrospective study, the investigators recently evaluated the correspondence of DAXX/ATRX expression on 41 EUS-FNB samples with corresponding surgical specimens demonstrating a 95.1% (almost perfect agreement, κ = 0.828; p < 0.001) and 92.7% (substantial agreement, κ = 0.626; p < 0.001) concordance for DAXX and ATRX expression, respectively. This study aims to evaluate the potential clinical/prognostic role of DAXX/ATRX expression as implementation of the currently used Ki67-based grading, evaluated on EUS-FNB samples in a prospective cohort of patients with NF-pNETs
This study aims to compare the surgical outcomes of laparoscopic spleen-preserving distal pancreatectomy using the Kimura technique versus the Warshaw technique. The primary focus is on the rates of unplanned splenectomy, occurrence of severe complications, as well as intraoperative and perioperative outcomes of both techniques.
pNENs still have a risk of recurrence after radical resection, and the overall recurrence and metastasis rate is as high as 13.7%-36.2% in China. At present, there is no standard adjuvant therapy for pNEN, and prospective studies are still lacking. This study was a randomized, double-blind, placebo-controlled, multicenter clinical trial to explore the efficacy and safety of surufatinib in the adjuvant treatment of pNET, in order to further improve the prognosis of patients and to provide high-quality research evidence for adjuvant therapy.
The aim of this study is to evaluate the impact of concomitant main pancreatic duct repair or reconstruction during minimally invasive pancreatic tumor enucleation on long-term patient prognosis and quality of life.
This study aims to evaluate the safety and efficacy of new ablation catheter developed by MEDICAL TAEWOONG for the treatment of pancreatic neoplasm (pancreatic adenocarcinoma or neuroendocrine tumour). The ablation is performed using EUSRA needle and radio frequency waves under ultrasound imaging. The subject who will be recruited into this study are patients who are deemed as non-surgical candidates.
This study aims to evaluate the safety and efficacy of new ablation catheter developed by MEDICAL TAEWOONG for the treatment of pancreatic premalignant and early malignant cystic lesion. The ablation is performed using EUSRA needle and radiofrequncy waves under ultrasound imaging. The method will be exaimened on patients who are candidates for surgical intervention and to examine the ability of the method to serve as an alternative to surgical intervention.
Investigator determined the factor of surgery associated with the survival of pancreatic neuroendocrine tumor.
