This phase II trial investigates side effects and how well donor stem cell transplant after chemotherapy works in treating pediatric and adolescent-young adults with high-risk solid tumor that has come back (recurrent) or does not respond to treatment (refractory). Chemotherapy drugs, such as fludarabine, thiotepa, etoposide, melphalan, and rabbit anti-thymocyte globulin 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 chemotherapy before a donor stem cell transplant helps kill cancer cells in the body and helps make room...
Due to lack of hormone overproduction in non-functioning pituitary adenomas (NFPAs), only the symptomatic adenomas or large adenomas with proven growth and risk for symptoms in near future will undergo pituitary surgery. The remaining adenomas are monitored regularly. Operation of these large adenomas will rarely remove all tumour tissue, and there is also a risk of worsening of pituitary function. Often, adenomas with the highest growth potential are operated several times and some also need radiation therapy, providing additional risk for pituitary failure. Unlike some of the hormone-producing adenomas, there is no established ...
High dose intravenous Methotrexate (HD-MTX) is the key drug in the treatment of primary central nervous system lymphoma (PCNSL). HD-MTX is usually delivered with time interval ranging from 10 to 21 days. Reduction of injection time interval is limited by MTX renal excretion and systemic toxicity. Glucarpidase (CPG2) is a recombinant bacterial rescue enzyme that cleaves circulating MTX into inactive metabolites, reducing plasma MTX concentrations within few minutes. The research hypothesis is that CPG2 used after HD-MTX injection allows to reduce time interval between MTX injections, increase dose intensity of the chemotherapy,...
The objective of this trial is to assess the safety and feasibility of delivering SBRT to patients with limited BMs (less than 10 lesions of lung cancer) by establishing the maximally tolerated dose (MTD) of SABR in 5 fractions.
The phase II study evaluate a light dose escalation in a classical intraoperative PDT regimen mediated by 5-ALA-PpIX, in glioblastoma patients with access to full surgical removal of the contrast enhancement. This treatment will be performed in addition to the current reference treatment of glioblastoma: maximum removal surgery followed by radiochemotherapy according to the Stupp protocol.
This study will investigate different doses of [177Lu]Lu-NeoB in combination with RT and TMZ in participants with newly diagnosed glioblastoma, with methylated or unmethylated promoter, to assess the safety and efficacy of [177Lu]Lu-NeoB in combination with the SoC and in recurrent glioblastoma as single agent, to identify the recommended dose and to also explore the safety of the PET imaging agent [68Ga]Ga-NeoB and characterize its uptake in the tumor area.
Background. Brain metastases (BM) are the most common intracranial tumor and occur in 20-40% of all oncological patients. The most common primary cancer in brain metastases is lung cancer, followed by melanoma, breast cancer, renal cancer and colorectal cancer. The incidence of brain metastases has been increasing but the occurrence of brain metastases is still associated with high morbidity and poor prognosis. The main treatment methods are stereotactic radiosurgery (SRS), microsurgical resection and whole brain irradiation (WBRT). In contrast to microsurgical resection, Gamma Knife radiosurgery (GKRS) is a non-invasive ...
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...
Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of special molecules called somatostatin receptors (SSTR). Somatostatin receptor scintigraphy and conventional imaging are used to detect NETs. This study proposes 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of somatostatin...
In this research study the investigators want to learn more about an alternate, local treatment for skin schwannomas. Specifically, local doxycycline intra-tumoral injection will be performed as a potential treatment for NF2-related skin schwannomas, ultimately reducing the risks and costs associated with standard surgical removal of such skin tumors if successful.
