Active clinical trials for "Pheochromocytoma"

RATIONALE: Radiolabeled octreotide can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells. PURPOSE: This phase I trial is to study the safety and effectiveness of radiolabeled octreotide in treating children who have advanced or refractory solid tumors.

The investigators will retrospectively analyze the clinical data of consecutive patients with pheochromocytomas and paragangliomas admitted between January 2018 and June 2020. The clinical characteristics of patients with and without dysglycemia will be compared, and whether surgery could improve the patients'dysglycemia will be also investigated.

Laparoscopic adrenalectomy has become the gold standard operation for non-malignant adrenal tumors replacing open adrenalectomy. The most popular lateral transperitoneal laparoscopic adrenalectomy (LTLA) approach has been recently challenged by an increasing popularity of the posterior retroperitoneoscopic adrenalectomy (PRA) approach which is believed by many surgeons as an easy to learn, reproducible and beneficial for patients. However, this belief is not evidence-based, so far. The aim of this study is to clarify if PRA is superior to the LTLA as minimally invasive approach to small and benign adrenal tumors.

This phase I trial studies the side effects and best dose of veliparib when given together with capecitabine and temozolomide in treating patients with neuroendocrine tumor that has spread to other places in the body and usually cannot be cured or controlled with treatment, has returned after a period of improvement, and cannot be removed by surgery. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as capecitabine and temozolomide, 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.

Determine the safety and effectiveness of Lu-177 DOTATOC in adult subjects with somatostatin receptor-expressing Pulmonary, Pheochromocytoma, Paraganglioma, Unknown primary, and Thymus neuroendocrine tumors or any other non-.GEP-NET. The treatment regimen will consist of 4 doses of 200 (±10%) mCi 177Lu-DOTATOC administered at 8+/- 1-week intervals.

Pheochromocytoma (pheo) is a catecholamine secreting tumor arising from chromaffin cells of the adrenal medulla in 90% of cases & in 10% is extra-adrenal arising from the sympathetic chain. It is malignant in 10% of cases, bilateral in 10% of patients & 10% of all pheo are inherited (Familial Pheo) as autosomal dominant either alone or as a part of multiple endocrine neoplasia (MEN) syndrome.In this prospective work, the investigators will try to compare the peri-operative hemodynamic course of Dexmedetomidine & magnesium sulphate (MgSo₄) infused patients with the traditional anesthetic technique (α₁ & β-adrenergic blockers plus vasodilators) during open surgical resection of Pheo. The investigators are aiming to check the safety & efficacy of the recommended technique on the peri-operative hemodynamic stability & controlling the hypertensive crisis during tumor manipulation.

This is a Phase I/II peptide receptor radiotherapy (PRRT) trial of 177Lu-DOTA-OCTREOTATE in children and adolescents with neuroendocrine tumors and pheochromocytoma or paraganglioma.

The phase I trial aims to determine the recommended phase II dose (RP2D) of vandetanib in combination with standard radiation therapy, 131I-mIBG, in patients with advanced phaeochromocytoma (phaeo) and paraganglioma (PG) by assessing the safety and tolerability of the combination treatment.

The study is designed to study the effectiveness of 123I-mIBG as a diagnostic imaging agent in evaluating patients with known or suspected neuroblastoma or phaeochromocytoma.

This phase II trial studies how well 177Lu-DOTATATE works in treating patients with rare endocrine cancers that have spread from where they started to nearby tissue or lymph nodes (locally advanced), spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Radioactive drugs, such as 177Lu-DOTATATE, may carry radiation directly to cancer cells and not harm normal cells. 177Lu-DOTATATE may help to control endocrine cancers compared to standard treatment.
