Filter by:This is a retrospective, monocentric study involving 50 patients with pancreatic neuroendocrine neoplasia resected between January 2008 and June 2020 at Paoli Calmettes Institute. The primary objective of the study is to evaluate the grade concordance rate, based on Ki67 obtained on the pre-operative micro-biopsy and the surgical specimen. Based on the histology slides obtained in the course of the treatment, several Ki67 recounts will be performed on pre-operative tumor micro-biopsies and on tumors resected after surgery: - a manual count (on photo printed in the hotspot area according to World Health Organization (WHO) 2017 recommendations, by an expert pathologist and a junior pathologist. - Automated counting using specific software based on artificial intelligence (Qpath software). On the other hand, clinical, surgical and anatomopathological data will be collected in order to follow the patient evolution.
The aim of the study is to generate real-world evidence to describe the patient experience of administration of Somatuline® Autogel® (lanreotide) in homecare and hospital settings, and the associated impact on healthcare utilisation, societal cost, work productivity and health-related quality of life (HRQoL)
The aim of this study is to evaluate the diagnostic performance of Al18F-NOTA-octreotide PET imaging in comparison with the current golden standard, 68Ga-DOTA-somatostatin analog PET, in neuroendocrine tumor patients.
The purpose of the study is to evaluate the effect of arginine/lysine solution administration on serum potassium levels. A systematic assessment of serum potassium levels will be performed during infusion and up to 24 hours post start of infusion compared to baseline.
Malnutrition and loss of muscle mass frequently occur in patients undergoing chemotherapy and can negatively effect therapy outcome. Especially patients with cancer of the gastrointestinal tract are often affected by malnutrition. Therefore, this study aims to examine changes in nutritional status of patients with cancer of the gastrointestinal tract during chemotherapy. Findings of this study will help to improve nutritional treatment of patients undergoing chemotherapy.
The primary purpose of this study is to examine the safety and potential effectiveness of a drug molecule called 64Cu-SARTATE as a potential new way to detect neuroendocrine cancers.
Peptide Receptor Radionuclide Therapy (PRRT) is based on specific somatostatin receptor targeting with radiolabelled analogues 90Y-DOTATOC and 177Lu-DOTATATE. These two most commonly used radiopeptides, 90Y-DOTATOC and 177Lu-DOTATATE, produce overall objective response rates of 15-35%. PRRT is generally well tolerated with mild toxicity, if the necessary precautions, such as the co-administration of nephroprotective amino acids or the adjustment of the administered activity, are taken. The main aim of this study is to evaluate the safety and the efficacy of neoadjuvant PRRT with 177Lu-DOTATATE followed by surgical resection for resectable non-functioning PanNETs at high risk of recurrence. The primary endpoint is the Rate of postoperative 90-day morbidity and mortality after neoadjuvant PRRT with 177Lu-DOTATATE followed by pancreatic resection and the secondary endpoints are: 1. Rate of objective radiological response to PRRT with 177Lu-DOTATATE according to RECIST criteria (version 1.1), for primary lesions' assessment, and modified RECIST criteria (mRECIST), for liver metastases' assessment, if detected 2. Quality of life (QoL) after neoadjuvant PRRT followed by pancreatic surgical resection. The study is designed as a prospective phase II single-arm trial. 8 Italian centers will participate to the study (6 surgical sites, 2 nuclear medicine sites). Patients will be recruited for 12 months. The study will end 2 months after operation of the last patient enrolled and the total duration of the study will be 24 months. Sample size estimation: 30 patients
The purpose of this study is to analyse clinical data of well-differentiated grade 3 digestive neuroendocrine tumors. These rare tumors may have a different disease evolution, response to chemotherapy and prognostic.
LM3 is a novel somatostatin receptor antagonist, while Gallium-68 DOTATATE is a typical somatostatin receptor agonist, This study is to evaluate the safety, biodistribution, dosimetry, and lesion detection ability of Gallium-68 labeled somatostatin receptor antagonist LM3 for the diagnostic imaging of metastatic, well-differentiated neuroendocrine tumors using positron emission tomography / computed tomography (PET/CT). The results will be compared between antagonist Gallium-68 labeled LM3 and agonist Gallium-labeled DOTATATE in the same group of patients. It will also be compared between the two different antagonists, Gallium-68 DOTA-LM3 and Gallium-68 NODAGA-LM3, in two parallel-designed arms.
Radioguided surgery (RGS) with beta- radioisotopes is a novel approach focused on developing a new probe which, detecting electrons and operating with low background, provides a clearer delineation of the margins of lesions with low radiation exposition for surgeons. To validate this procedure, ex vivo specimens of tumours expressing somatostatin receptors, as small-intestine neuroendocrine (SI-NET), will be tested
