Filter by:The 2017 World Health Organization (WHO) introduced a new category of high-grade, well-differentiated neuroendocrine neoplasms (NENs) that called neuroendocrine tumors (NETs) G3 in pancreatic NENs classification and, then, in 2019, for all gastro-entero-pancreatic (GEP) tract NENs. The new classification made it possible to separate NETs G3 from high-grade, poorly-differentiated, NENs that are called neuroendocrine carcinomas (NECs). However, in clinical practice, we observed that several clinical, pathological and radiological differences are arising among NET G3 patients, suggesting that a multiparametric definition of NET G3 is needed.
The objective of the study is to create a common and unique platform for the acquisition of biological samples and, subsequently, the possible identification of predictive and prognostic biomarkers for young adults with gastrointestinal and neuroendocrine cancers.The definition "adolescent and young adults (AYA)" covers a broad group of patients ranging from the upper limit of the paediatric competence to the youngest patients usually considered and treated as adults. However, a well-defined and universally accepted age range is still not established. Young adults with cancer have distinct epidemiological, biological, and clinical characteristics, as well as special medical and psychosocial needs that are often unmet. In consideration of their poor representation in clinical studies, as well as the rarer, albeit increasing, frequency at an epidemiological level, knowledge of the risk factors associated with cancers in young adults is very poor. It is therefore of fundamental importance to focus attention on this specific cohort of patients, in order to describe in ever more detail any specific biomolecular aspects, and make full use of the pharmacological resources currently available.
The clinical diagnosis and treatment data of 300 cases of cervical neuroendocrine tumors were collected, including age, preoperative biopsy pathology results, postoperative histopathological results, TCT results, and colposcopy biopsy pathology results. At the same time, paraffin tissue specimens (remaining specimens after pathological diagnosis) from 100 cases of cervical neuroendocrine tumors from multiple centers across the country were collected to establish a cervical neuroendocrine tumor data follow-up database. Protein concentration and omics analysis were performed on the data results, to evaluate the molecular characteristics and prognosis of cervical neuroendocrine tumor proteins, and to preliminarily explore its clinical application value.
PM8002 is a bispecific antibody targeting PD-L1 and VEGF. This study will evaluate the efficacy and safety of PM8002 in combination with FOLFIRI as second line treatment for neuroendocrine neoplasm (NEC and Ki-67≥55% G3 NET).
This is a phase II, single arm, open-label, multicenter study to evaluate the efficacy and safety of Sintilimab combined with IBI310 and Surufatinib for the treatment of high-grade advanced-neuroendocrine neoplasm
The purpose of this study is to explore the efficacy and safety of chidamide combined with sintilimab in chemotherapy-refractory advanced high-grade neuroendocrine neoplasm.
This project intends to analyze the molecular biological characteristics of NEN based on multi-omics, develop an exclusive NEN multi-omics big data platform, and carry out molecular subtypes and potential targets prediction, so as to improve the therapeutic effect of neuroendocrine tumors.
The aim of this study is to use single-cell sequencing technology to explore neuroendocrine neoplasm (NEN) molecular biological characteristics, tumor heterogeneity and cell subtypes. Besides. NEN models are constructed for basic research, including primary cell lines, organoids, and animal models.
In this study, we want to randomize patients with neuroendocrine neoplasms (NENs) who are eligible for peptide receptor radionuclide therapy (PRRT), to either standard PRRT consisting of 4 treatments with 7.4 GBq Lu-177-DOTATOC (standard arm) or 4 treatments with individualized doses of Lu-177-DOTATOC (dosimetry arm). In the dosimetry arm, the first dose depends on the patients' kidney function and thereafter the absorbed dose to the kidneys at the previous treatment. A max of 20GBq will be administered at the first treatment and 25GBq at treatment 2-4. We aim to reach an accumulated kidney dose of 24Gy. After the first treatment all patients will go through three SPECT/CT scans 24 hours, 4 days, and 7 days, after treatment to calculate absorbed kidney dose. The patients in the standard dose treatment arm will have one SPECT/CT scan after each of the last three treatments; all performed 24 hours after treatment, used to approximate the kidney dose assuming the clearance of the Lu-177 DOTATOC is the same after all treatments. The patients in the dosimetry based treatment arm will go through three SPECT/CT scans after all four treatments for dosimetry calculation. Bone marrow dosimetry is calculated after all treatments in the dosimetry based treatment arm and after the first treatment in the standard treatment arm. For bone marrow dosimetry, blood samples are drawn right before administration of Lu-177 DOTATOC (time 0) and 3 minutes, 45 minutes, 2 hours, 4 hours, 7-8 hours, 24 hours, 4 days, and 7 days after administration of Lu-177 DOTATOC. Standard blood samples are routinely drawn every 2nd week after every treatment in all included patients and analysed regarding liver, kidney and bone marrow function. Kidney clearance is evaluated with Tc-DTPA clearance at baseline. Blood and urinary samples will be collected at baseline and 3 months after the last treatment for kidney fibrosis analyses. At baseline, blood and urine samples are collected for a biobank. All included patients fill in validated quality of life questionaires at all treatments. To evaluate the effect of the treatment, all patients will be evaluated with standard CT scans prior to treatment and 3 and 9 months after the 4th treatment. Ga-68 DOTATOC PET will be performed at baseline and 6 and 12 months after the last treatment.
This phase Ib trial is to find out the best dose, possible benefits and/or side effects of peposertib when given together with lutetium Lu 177 dotatate in treating patients with neuroendocrine tumors. Peposertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell formation, so as to help block the formation of growths that may become cancer. Radioactive drugs, such as lutetium Lu 177 dotatate, may deliver radiation directly to tumor cells and not harm normal cells. Adding peposertib to lutetium Lu 177 dotatate may kill more tumor cells.
