Active clinical trials for "Hemangioendothelioma"

The study will use blood (serum and plasma) and tissue obtained from participants undergoing prescribed surgical resection of vascular anomalies of interest proposed in this study. The study will also use blood (serum and plasma) and tissue collected and stored in a tissue bank maintained by the Department of Hematology/Oncology.

Hepatic tumors in the perinatal period are associated with significant morbidity and mortality in affected patients. The conventional diagnostic tool, such as alpha-fetoprotein (AFP) shows limited value in diagnosis of infantile hepatic tumors. This retrospective-prospective study is aimed to evaluate the diagnostic efficiency of the deep learning system through analysis of magnetic resonance imaging (MRI) images before initial treatment.

In this research study we want to learn more about which treatment works better for patients diagnosed with a vascular tumor called Kaposiform Hemangioendothelioma (KHE) or other high risk vascular tumors such as Tufted Angioma (TA). In these tumors, the blood cells that help your blood clot called platelets become trapped in the tumor causing swelling, pain, and bruising. Vascular tumors can be life threatening. There are few medical treatments that will work to shrink the vascular tumor. Some doctors will use steroids and vincristine to try and shrink vascular tumors. In this research study, the study doctor will compare two different drugs to see which one will work better to help shrink your vascular tumor. One of the drugs is vincristine. Vincristine is approved by the Food and Drug Administration (FDA) to treat people with cancer. Vincristine is used to stop the abnormal cells from growing such as cells that make up blood vessels. The other drug to be used in this study is sirolimus. Sirolimus is currently approved by the Food and Drug Administration (FDA) to prevent transplanted organ rejection. Sirolimus is not approved by the FDA for treatment of vascular abnormalities and is considered experimental. Sirolimus belongs to a class of drugs call 'mTOR inhibitors'. mTOR (mammilian target of rapamycin) helps cells to grow and may also help blood vessels to grow in a more normal fashion. Sirolimus is currently being tested in patients with vascular tumors and cancer. In vascular tumors, we hope sirolimus will stop the blood vessel growth.

Kaposiform hemangioendothelioma (KHE) is a rare vascular neoplasm that occurs predominantly in infancy or early childhood. KHE has a nearly equal sex ratio. The annual incidence of KHE has been estimated at 0.071 per 100,000 children. KHE presents with intermediate-malignant and locally aggressive characteristics but without distant metastases. This pilot trial studies sirolimus versus sirolimus plus pednisolone in treating patients diagnosed with kaposiform hemangioendothelioma (KHE) and Kasabach-Merritt phenomemon (KMP) that cannot be removed by surgery. The purpose of this study is to compare the efficacy and safety of orally administered sirolimus versus sirolimus plus pednisolone in the treatment of KHE associated with KMP.

to evaluate the safety and efficacy of Low-dose sirolimus in Kaposiform Hemangioendothelioma in Chinese children by a prospective, randomized open trial.

This phase II trial studies how well trametinib works in treating patients with epithelioid hemangioendothelioma that has spread to other places in the body (metastatic), nearby tissue or lymph nodes (locally advanced), or cannot be removed by surgery (unresectable). Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This randomized phase II trial studies how well gemcitabine hydrochloride works with or without pazopanib hydrochloride in treating patients with refractory soft tissue sarcoma. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Pazopanib hydrochloride may also stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether gemcitabine hydrochloride is more effective with or without pazopanib hydrochloride in treating patients with soft tissue sarcoma.

This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and to see how well they work in treating patients with advanced or metastatic sarcoma. Vismodegib may slow the growth of tumor cells. Gamma-secretase/notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vismodegib together with gamma-secretase/notch signalling pathway inhibitor RO4929097 may be an effective treatment for sarcoma.

The purpose of this study is to compare the efficacy and safety of different concentration gradients of sirolimus in the treatment of Kaposiform hemangioendothelioma.

This randomized controlled trial aims to compare guided discontinuation with maintenance treatment of sirolimus in pediatric patients with KHE.
