Filter by:This is an open-label phase II study of an investigational drug, anlotinib in participants with advanced malignant paraganglioma or pheochromocytoma. Pheochromocytoma and paraganglioma (PPGL) are tumors originating from the adrenal medulla or adrenal diplomatic sensory chain, respectively, which can synthesize and secrete large amounts of catecholamines. In this study, participants whose disease has advanced or spread despite prior standard therapy, will receive anlotinib for 2-weeks followed by a 1-week rest period, until disease progression (PD) or drug toxicity intolerance. Anlotinib is an investigational drug, which has been shown to shrink tumours in several tumour models. The study will evaluate the efficacy as well as the toxicity profile of anlotinib when used as an alternative treatment for participants with PPGL tumours.
PHEOCHROMOCYTOMA (PCC)/ PARAGANGLIOMA are catecholamine secreting tumors with varied manifestations. Besides hypertension, PCC patients may have subclinical to overt cardiac and vascular dysfunction, which are important to recognize to minimize perioperative morbidity and mortality. Cardiovascular (CV) dysfunction can be in the form of hypertension, left ventricular (LV) hypertrophy, heart failure, cardiomyopathy, dysrhythmias, angina and Myocardial infarction. Literature search revealed a few retrospective and a few prospective studies, including one prospective follow up study conducted at SGPGIMS to document CV changes in PCC. Our institutional study was the first to document the nature and extent of CV dysfunction and cardiomyopathy and their reversal after surgical cure. The studies revealed that PCC patients had significantly higher LV mass index, higher LV diastolic dysfunction, subclinical impaired LV systolic function. Earlier studies postulated apparent improvement in various cardiac indices even with selective α-blockade and continued after surgical cure, with near normalization at 3 -6 months postoperatively. Detailed cardiac and vascular evaluation in PCC patients can be of help in preoperative optimization of cardiac risk and may provide prognostic information The literature on PCC-mediated CV dysfunction and catecholamine cardiomyopathy is largely limited to case reports and retrospective studies, with few reports of their reversal after curative PCC operations. Whether the duration of disease influence the function of heart was not apparently addressed in earlier trials. Trials that established the differences in the degree of cardiac dysfunction between normotensive and hypertensive PCC patients involved smaller proportion of study subjects. Sub clinical changes in endomyocardium was presumed but not objectively assessed and hence its reversal after surgical cure is uncertain. The aim of this research is to study the cardiac and vascular changes in Pheochromocytoma/ Paraganglioma patients and their reversal following curative surgery
The aim of this study is to evaluate the diagnostic performance and tumor burden of 18F-metafluorobenzylguanidine (18F-MFBG) positron emission tomography (PET) in patients with neuroendocrine tumors mainly in pheochromocytoma and paraganglioma (PPGL) and neuroblastoma (NB).
This is a study to evaluate the efficacy and safety of belzutifan monotherapy in participants with advanced pheochromocytoma/paraganglioma (PPGL), pancreatic neuroendocrine tumor (pNET), von Hippel-Lindau (VHL) Disease-Associated Tumors, Advanced Gastrointestinal Stromal Tumor (wt GIST), or Advanced Solid Tumors With hypoxia inducible factor-2 alpha (HIF-2α) related genetic alterations. The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).
The aim of our study is to compare plasma metanephrines in patients with cyanotic and acyanotic congenital heart disease and possible association with chronic hypoxic stress.
This phase II trial studies how well anlotinib hydrochloride works in treating patients with metastatic pheochromocytoma or paraganglioma. Anlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
Phaeochromocytomas and paragangliomas (PPGLs) are tumours of the adrenal medulla and extra-adrenal sympathetic nervous system, some which can become metastatic. It is a very rare disease and the tumours are often detected late. Approximately 50 % of the tumours are caused by germline genetic variants screening programmes are recommended for patients and their family members; however, they are not yet well-targeted with respect to individual prognosis. In this study the investigatorscaim to characterize the genotype-phenotype associations in all Danish patients (n=400) diagnosed with PPGLs who have been followed in tertiary centres using medical records and national registries. To this end novel immunohistochemical, genetic, and epigenetic biomarkers in tumour tissues samples from biobank material (blood samples and tumour tissue) will be investigated to develop a comprehensive predictive algorithm for disease prognosis. The study will provide a clinical tool for an improved targeted screening program and subsequently prevention of disease development.
This is a multicenter, open-label, single-arm study to evaluate the safety and dosimetry of Lutathera in adolescent patients 12 to <18 years old with somatostatin receptor positive GEP-NETs and PPGLs. The study will enroll at least 8 patients in the GEP-NET cohort and as many adolescents with PPGL as possible in the exploratory PPGL cohort.
Patients affected by pheochromocytoma (PHEO) have brown-adipose tissue (BAT) hyperactivation. They perform, in routine settings, a FDG PET-CT scan. The high metabolic activity of BAT and its ability to consume both glucose and fatty acid suggest that it may have potential as a therapeutic target in the treatment of obesity. However, alternative non-invasive techniques to PET-CT BAT detection still need more validation. Accordingly, our aim will be to measure the temperature and microcirculation of the skin overlaying BAT depots in the region of FDG-uptake detected by 18F-FDG PET/CT before and after a cold test in PHEO patients.
Qualitative and quantitative biomarker of response to radiotherapy is needed in paragangliomas. We aim at assessing the added value of 1H-SRM for the evaluation of early response to EBR therapy in patients with cervical SDHx PGL.
