This study aims to define the natural history of men at high genetic risk for prostate cancer on the basis of specific germline genetic mutations, family history, or Black/African ancestry and evaluate the utility of prostate MRI as a screening tool. The hypothesis is that this targeted population of men are at elevated risk of developing prostate cancer compared to the general population, and enhanced screening with MRI will enable early detection and diagnosis of potentially aggressive prostate cancer, characterization of the penetrance of specific mutations, and potentially identify new genetic risk mutations.

The RECMAP-study: Resection With or Without Intraoperative Mapping for Recurrent Glioblastoma
Erasmus Medical Center Glioblastoma, IDH-wildtype Glioblastoma Glioblastoma Multiforme of Brain Astrocytoma, Malignant Brain Neoplasms
Resection of glioblastoma in or near functional brain tissue is challenging because of the proximity of important structures to the tumor site.

Resection of glioblastoma in or near functional brain tissue is challenging because of the proximity of important structures to the tumor site. To pursue maximal resection in a safe manner, mapping methods have been developed to test for motor and language function during the operation. Previous evidence suggests that these techniques are beneficial for maximum safe resection in newly diagnosed grade 2-4 astrocytoma, grade 2-3 oligodendroglioma, and recently, glioblastoma. However, their effects in recurrent glioblastoma are still poorly understood. The aim of this study, therefore, is to compare the effects of awake mapping and asleep mapping with no mapping in resections for recurrent glioblastoma. This study is an international, multicenter, prospective 3-arm cohort study of observational nature. Recurrent glioblastoma patients will be operated with mapping or no mapping techniques with a 1:1 ratio. Primary endpoints are: 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months after surgery and 2) residual tumor volume of the contrast-enhancing and non-contrast-enhancing part as assessed by a neuroradiologist on postoperative contrast MRI scans. Secondary endpoints are: 1) overall survival (OS), 2) progression-free survival (PFS), 4) health-related quality of life (HRQoL) at 6 weeks, 3 months, and 6 months after surgery, and 4) frequency and severity of Serious Adverse Events (SAEs) in each arm. Estimated total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM).

The PALSUR-study: Palliative Care Versus Surgery in High-grade Glioma Patients (ENCRAM 2203)
Jasper Gerritsen Glioblastoma Glioblastoma Multiforme Glioblastoma, IDH-wildtype Glioblastoma Multiforme, Adult

There is no consensus on the optimal treatment of patients with high-grade glioma, especially when patients have limited functioning performance at presentation (KPS ≤70). Therefore, there are varied practice patterns around pursuing biopsy, resection, or palliation (best supportive care). This study aims to characterize the impact of palliative care versus biopsy versus resection on survival and quality of life in these patients. Also, it will aim to determine if there is a subset of patients that benefit the most from resection or biopsy, for which outcome, and how they could be identified preoperatively. This study is an international, multicenter, prospective, 3-arm cohort study of observational nature. Consecutive HGG patients will be treated with palliative care, biopsy, or resection at a 1:3:3 ratio. Primary endpoints are: 1) overall survival, and 2) quality of life at 6 weeks, 3 months and 6 months after initial presentation based on the EQ-5D, EORTC QLQ C30 and EORTC BN 20 questionnaires. Total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year.

There are no guidelines or prospective studies defining the optimal surgical treatment for gliomas of older patients (≥70 years) or those with limited functioning performance at presentation (KPS ≤70). Therefore, the decision between resection and biopsy is varied, amongst neurosurgeons internationally and at times even within an instiutition. This study aims to compare the effects of maximal tumor resection versus tissue biopsy on survival, functional, neurological, and quality of life outcomes in these patient subgroups. Furthermore, it evaluates which modality would maximize the potential to undergo adjuvant treatment. This study is an international, multicenter, prospective, 2-arm cohort study of observational nature. Consecutive HGG patients will be treated with resection or biopsy at a 3:1 ratio. Primary endpoints are: 1) overall survival (OS) and 2) proportion of patients that have received adjuvant treatment with chemotherapy and radiotherapy. Secondary endpoints are 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months and 6 months after surgery 2) progression-free survival (PFS); 3) quality of life at 6 weeks, 3 months and 6 months after surgery and 4) frequency and severity of Serious Adverse Events (SAEs).

The purpose of this study is to find out if pulsed dye laser treatment or timolol maleate 0.5% gel can help infants who have a hemangioma. The investigators also want to find out if pulsed dye laser treatment and timolol maleate 0.5% gel are safe to use without causing too many side effects. Hemangioma is a common type of birthmark. These birthmarks happen when many new blood vessels grow in a specific area on the skin. Blood vessels are tiny tubes that carry blood through the body. No one knows what causes blood vessels to group together. Most birthmarks don't hurt at all and they usually aren't a sign of any kind of illness. Lots of newborns have these birthmarks on their bodies, like between the eyebrows. These birthmarks usually disappear within the first few months to years of life. These birthmarks tend to disappear spontaneously. Most hemangiomas are not treated unless the hemangioma threatens the child's health, which occurs in about 1 in 3 children with hemagiomas. Pulsed dye laser is widely used in children, and is approved by the U.S. Food and Drug Administration (FDA) for treating hemangioma. The FDA has approved timolol maleate to treat glaucoma in adults, but the FDA has not approved timolol maleate to treat hemangiomas in children. About 7 infants with hemangiomas have received timolol maleate. The results so far show that timolol maleate may be helpful and safe in treating hemangiomas in infants. An important question being tested in this study is whether pulsed-dye laser or timolol maleate can prevent hemangioma from growing when used very early after birth.

This phase III trial studies the side effects of inotuzumab ozogamicin and how well it works when given with frontline chemotherapy in treating patients with newly diagnosed B acute lymphoblastic leukemia. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a chemotherapy drug called ozogamicin. Inotuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD22 receptors, and delivers ozogamicin to kill them. Chemotherapy drugs, such as [intervention], work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving inotuzumab ozogamicin with chemotherapy may work better in treating young adults with B acute lymphoblastic leukemia.
