Filter by:This study evaluates the possibility and the safety of performing local therapy for Pancreatic neuroendocrine neoplasms (PanNENs) using radiofrequency ablation of the tumor under ultrasonography (EUS) guidance.
Medullary carcinoma (MC) is a rare tumor with solid growth pattern without glandular differentiation and constitute less than 1% of colorectal cancer. Lymph node positivity and distant organ metastasis were reported to be lower than other poorly differentiated adenocarcinomas. Therefore, the diagnosis of MC is pathologically important in terms of follow-up and treatment. MC is commonly localized in the right colon, has a large tumor size, and is mostly diagnosed in the T4 stage. As MC most likely have defects in DNA MMR, the correct pathological diagnosis is important for the postoperative treatment and the prognosis of the patients.
This is a prospective observational study which aims to evaluate; The prevalence of pancreatic insufficiency in patients with pancreatic malignancies (adenocarcinoma and neuroendocrine tumours). The most appropriate diagnostic strategy. The impact that an adequate diagnosis and treatment may have on patients' outcome.
This phase Ib trial studies how well pembrolizumab works with combination chemotherapy in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate that has spread to nearby tissue or lymph nodes or that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as etoposide, docetaxel, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab with platinum-based chemotherapy may work better in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate.
This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb20717, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb20717 in subjects with selected advanced solid tumors.
The purpose of the AveNEC trial is to investigate the clinical activity and safety of avelumab in patients with NEC G3 (WHO 2010), including "NET G3" who are progressive after first line chemotherapy.
Observational, multicentre, retrospective study on patients taken care according to the national guidelines. The objective is to define, after the diagnosis confirmation, the frequency of PD-L1 expression in patients with large-cell lung neuroendocrine carcinoma (NEC), whatever the stage of the disease, and to correlate this parameter to clinical data at the time of diagnosis, therapeutic response and survival. Large-cell NECs present a bad prognostic and there is no evidence of treatment for these patients with advanced disease in second ligne of treatment at that time. To demonstrate the PD-L1 expression in this type of cancer might have a major therapeutic impact in a close future to access immunotherapies.
This is a single-center, single-arm, open-label, pilot trial to evaluate the efficacy and safety of avelumab in subjects with unresectable or metastatic, Grade 3, poorly-differentiated neuroendocrine.carcinoma.
The study is a phase I multicentre randomized, open, parallel-arm clinical trial conducted to investigate the IMP, namely 111In-CP04. The study consists of preclinical (to establish a clinically useful formulation for the radiolabelled peptide CP04), and a clinical step. The main objective of the clinical part of the project is to establish the safety of i.v. administration of a high peptide amount and to assess the tracer biodistribution and dosimetry in MTC and normal tissues and to determine critical organs as well as the evaluation of the potential of CCK2 receptor scintigraphy to detect cancer lesions for both low (10ug) and high (50ug) peptide amount and the decrease of kidney dose after co-administration of gelofusine /gelaspan as a nephroprotective agent. To achieve this, the following study design has been accepted: the first 4 patients will receive 2 peptide amount of CP04: low peptide amount (for diagnostic purpose) and high peptide amount (for therapeutic purpose) of CP04. If no SAE is present, the remaining pts will be randomized for 2 arms: high peptide amount of 111In-CP04 with and without gelofusine/gelaspan infusion. It is expected that CCK-2/gastrin receptor imaging will become a valid diagnostic method for a specific non-invasive staging and follow-up of patients with MTC, and treatment of recurrent and disseminated disease will be more efficient with minimized nephro- and myelotoxicity (if 111In labelled).
