Background: Lu177 DOTATATE Peptide Receptor Radionucleotide Therapy (PRRT) was FDA approved in the United States in 2018, however, the data for the safety and efficacy of repeat PRRT are almost exclusively from European centers. We present an updated experience with repeat PRRT in a cohort of US patients.Methods: We used our single-center longitudinal IRB approved neuroendocrine tumor (NET) registry to identify patients who had been previously treated wi...

Background: Clinicians are concerned about increased hepatotoxicity in patients who received hepatic artery bland embolizations (TAE) and subsequent Peptide Receptor Radionuclide Therapy (PRRT). The body of literature describing the safety of PRRT following prior TAE is very limited. The purpose of this study is to evaluate the degree of long-term liver toxicity in patients who received PRRT in addition to previous hepatic embolizations for liver dominant disease.<p class=...

Background: Grade 3 (G3) gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) are aggressive tumors with poor survival outcomes for which medical management is usually recommended. This study sought to evaluate outcomes of surgically treated G3 GEP-NEN patients.Methods: A single-institutional prospective NEN database was reviewed. Patients with G3 GEP-NENs based on World Health Organization (WHO) 2019 definitions included well-differentiated neur...

Background: Grade 3 (G3) gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) are rare, aggressive tumors with poor prognosis. The WHO 2017 classification further subdivided G3 NENs into G3 neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs). Current guidelines favor medical management in most of these patients, and the role of surgical management is not well-defined. We performed a systematic literature review and meta-analysis of surgical management vs ...

We are all aware of the current anxieties over the future of Academic Medicine and Modernising Medical Careers. 10 years ago the BMA cohort of 1995 Medical graduates: Medical Academic Career Intentions was performed. 545 doctors graduating in 1995 were followed up for 10 years. The key findings included: those doctors working in research were doing so to improve future career prospects or as a means to secure a National Training Number (NTN). However being in the transition pe...

MD are the most frequent complaint of women with Cushing Syndrome at the time of diagnosis.Objective: To study the frequency of occurrence of MD in patients with Syndrome Cushing and to characterize their clinical and hormonal parallels. We investigated 34 women (average age of 27 years, variation in age from 18 to 30 years) with a newly identified ACTHA. The patients were divided into 4 groups: (1) the normal cycle is 26–31 days; (2) oligomenorrhea...

Background: Preoperative grading of pancreatic neuroendocrine tumors (PNET) incorporating Ki-67 index can identify PNETs at low risk of progression and prevent unnecessary surgical resection. The aim of this study was to perform a comprehensive literature search and meta-analysis to compare the accuracy of Ki-67 based grading of PNETs between endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) vs fine needle biopsy (FNB).Methods: Literature s...

Background: Peptide Receptor Radionuclide Therapy (PRRT) is effective for gastroenteropancreatic (GEP) neuroendocrine tumors (NETs) and received FDA approval after demonstrating improved progression-free-survival (PFS) in advanced midgut NETs. We investigated a two-decade experience with PRRT, hypothesizing that PRRT confers PFS and overall-survival (OS) advantages in patients who progress after surgery.Methods: A single-institutional NET database was re...

Background: New therapeutics and combinations are needed to improve the survival of patients with advanced, metastatic pancreatic NETs (pNETs). RABL6A is a novel oncogenic driver of pNET pathogenesis that acts through multiple oncogenic pathways. Kinome and phosphoproteome analyses of proliferating (RABL6A-positive) pNET cells, vs arrested (RABL6A-knockdown) controls, demonstrated that druggable cyclin-dependent kinase 4 and 6 (CDK4/6) and MEK kinases are activated in growing ...

Background: Patients with small bowel neuroendocrine tumors (SBNETs) frequently present with metastatic disease, and unfortunately, the range and efficacy of available therapies is limited. Immunotherapeutic checkpoint inhibitors have demonstrated benefit in other malignancies and may also play a role in SBNETs, although relatively little is known about the immune infiltrate in these tumors. Toward a goal of developing novel immunomodulatory strategies, we sought to evaluate t...
