Fluorescence imaging using indocyanine green has shown promising results for the intraoperative localization of small pancreatic neuroendocrine tumors. In a case report involving five patients, successful tumor identification and laparoscopic partial resections were achieved without serious complications. Pathological reviews confirmed four neuroendocrine tumors of G1…
Peptide receptor radionuclide therapy (PRRT) significantly improves progression-free survival (PFS) and overall survival (OS) in patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who progress after surgical resection. Among 237 analyzed patients, those receiving PRRT experienced a median PFS of 32.4 months compared to 11.0 months…
A prospective multicenter study evaluated endoscopic ultrasonography-guided ethanol injections (EUS-EI) for treating small pancreatic neuroendocrine neoplasms (PNENs). Of the 25 patients treated, 76% achieved the primary endpoint compared to surgical outcomes, and 88% attained complete ablation at 1 and 6 months. Safety results were promising,…
Mural nodules protruding into the lumen and intraluminal air serve as significant predictors of neuroendocrine tumors in patients with acute appendicitis. In a study involving 1,150 patients, those with neuroendocrine tumors exhibited a mural nodule prevalence of 53.3% sensitivity and 95.8% specificity, while intraluminal air…
A novel Liver Metastasis Score (LMS) effectively predicts liver metastasis risk for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) post-surgery. Among 724 patients studied, 9.1% developed liver metastasis, significantly impacting survival rates (63.6% vs. 95.8% for no metastasis). Key risk factors identified include Ki-67 index, vascular…
A novel machine-learning model effectively predicts the malignant potential of gastric gastrointestinal stromal tumors (GISTs), identifying key risk factors such as endoscopic ultrasound features, tumor margin clarity, diameter, and monocyte-to-lymphocyte ratio. Tested with 318 patients, the logistic classification model achieved high performance with area under…
Higher preoperative glycosylated hemoglobin A1C (HbA1c) levels significantly affect long-term outcomes in patients undergoing resection for nonfunctional gastroenteropancreatic neuroendocrine tumors (GEP-NETs). A study involving 190 patients revealed that those with HbA1c ≥ 6.5% experienced increased complications and markedly reduced median overall survival (89.8 months vs.…
Evidence suggests that surgical intervention, prior to peptide receptor radionuclide therapy, significantly enhances progression-free survival for patients with metastatic gastroenteropancreatic neuroendocrine tumors. In a study of 89 well-matched patients, those who underwent surgery had a median progression-free survival of 26.1 months, compared to 15.6 months…
A meta-analysis involving 2,978 patients confirms that endoscopic ultrasound-guided fine needle acquisition (EUS-FNA/B) is an effective method for diagnosing and pre-operatively grading pancreatic neuroendocrine tumors (PANNETs). The overall concordance rate with surgical grading was 0.77, with a notable increase in the G1 subgroup (0.88). Notably,…
In a study assessing salvage treatments for rectal neuroendocrine tumors (RNETs) under 10 mm, wide hot snare polypectomy (WHSP) showed superior outcomes. Of 121 patients analyzed, WHSP achieved an impressive 72.7% R0 resection rate compared to other methods. With a focus on effectiveness and safety,…
