Filter by:Readmissions increasingly serve as a metric of hospital performance, inviting quality improvement initiatives in both medicine and surgery. Recently, a readmission reduction program in the United States was associated with significantly shorter length of stay, earlier discharge, and reduced 30-day readmission after elective neurosurgery. These results underscore the importance of patient education and surveillance after hospital discharge, and it would be beneficial to test whether the same approach yields beneficial results in a different health system, the NHS. In this study, the investigators will replicate the Transitional Care Program (TCP) published by Robertson et al.(Journal of Neurosurgery 2017) with the goal of decreasing length of stay, improving discharge efficiency, and reducing readmissions in neurosurgical patients by optimizing patient education and post-discharge surveillance.
Primary malignant and non-malignant brain tumors account for an estimated 21.42 cases per 100,000 for a total count of 343,175 incident tumors based on worldwide population estimates [1]. These entities result in variable but disappointing rates of survival, particularly for primary brain tumors (5-year survival rates: anaplastic astrocytoma 27%; glioblastoma multiforme 5%) [2, 3]. Metastatic brain tumors outnumber primary brain tumors (estimates as high as 10:1) as they affect approximately 25% of patients diagnosed with cancer [4-6]. In terms of brain tumor surgery, the extent of surgical resection-a factor that is greatly impacted by a Neurosurgeon's ability to visualize these tumors-is directly associated with patient outcomes and survival [7-9]. Although spinal cord tumors are lower in terms of their incidence [10], data correlating extent-of-resection to outcomes and survival have been demonstrated in patients with intramedullary tumors [11]. Using systemically delivered compounds with a high sensitivity of detection by near-infrared (NIR) fluorescence, it would be possible for us to improve surgical resection thus minimizing chances of recurrence and improving survival. Simply, if the tumor cells will "glow" during surgery, the surgeons are more likely to identify tumor margins and residual disease, and are, therefore more likely to perform a superior cancer operation. By ensuring a negative margin through NIR imagery, it would make it possible to decrease the rates of recurrence and thus improve overall survival. This concept of intraoperative molecular imaging requires two innovations: (i) a fluorescent contrast agent that can be injected systemically into the subject and that selectively accumulates in the tumor tissues, and (ii) an imaging system that can detect and quantify the contrast agent in the tumor tissues.[12, 13] Subjects undergo intraoperative imaging, receiving an injection of indocyanine green and then undergoing intraoperative imaging of the surgery site with a NIR imaging system. The imaging devices allow the operating field to be observed in real-time.
The goal of this clinical research study is to establish the safety of direct administration of 5-Azacytidine into the fourth ventricle of the brain or resection cavity in patients with recurrent posterior fossa ependymoma.
The goal of this clinical research study is to establish the safety of simultaneous infusions of methotrexate and etoposide into the fourth ventricle of the brain or resection cavity in patients with recurrent malignant posterior fossa brain tumors. These tumors include medulloblastoma, ependymoma, atypical teratoid/rhabdoid tumor or other malignant brain tumor with recurrence or progression involving anywhere in the brain and/or spine. Patients' disease must have originated in the posterior fossa of the brain.
Primary brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months. Glioma is the most common form of primary brain cancer, afflicting approximately 7,000 patients in the United States each year. These highly malignant cancers remain a significant unmet clinical need in oncology. GBM often has a high expression of EFGR (Epidermal Growth Factor Receptor), which is associated with poor prognosis. Several methods of inhibiting this receptor have been tested, including monoclonal antibodies, vaccines, and tyrosine kinase inhibitors. The investigators hypothesize that in patients with recurring GBM, intracranial superselective intra-arterial infusion of Cetuximab (CTX), at a dose of 250mg/m2 in conjunction with hypofractionated radiation, will be safe and efficacious and prevent tumor progression in patients with recurrent, residual GBM.
This is a Phase I clinical trial evaluating abemaciclib (LY2835219), an inhibitor of cyclin dependent-kinases 4 and 6 (Cdk 4/6) in children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) (Stratum A) and in relapsed/refractory/progressive malignant brain (Grade III/IV, including DIPG; MBT) and solid tumor (ST) patients (Stratum B).
The goal of this clinical research study is to establish the maximum tolerated dose (MTD) of direct administration of methotrexate into the fourth ventricle of the brain in patients with recurrent malignant brain tumors including medulloblastoma, primitive neuroectodermal tumors (PNET), atypical teratoid/rhabdoid tumors (AT/RT), and ependymoma. Methotrexate is designed to block cancer cells from dividing, which may slow or stop their growth and spread throughout the body. This may cause the cancer cells to die.
This study is for patients that have brain cancer. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting immune cells present in the blood that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise, but have not been strong enough to cure most patients. The antibody used in this study is called anti-HER2 (Human Epidermal Growth Factor Receptor 2). This antibody sticks to tumor cells because of a substance on the outside of these cells called HER2. Many types of brain tumors are positive for HER2 . HER2 antibodies have been used to treat people with HER2-positive cancers. For this study, the HER2 antibody has been changed so that instead of floating free in the blood it is now attached to T cells. When an antibody is joined to a T cell in this way it is called a chimeric antigen receptor (CAR). These CAR-T cells seem to be able to kill tumors like the one these patients have, but they don't last very long and so their chances of fighting the cancer are limited. Therefore, developing ways to prolong the life of these T cells should help them fight cancer. These HER2-CAR T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the largest safe dose of HER2-CAR T cells, to learn what the side effects are, and to see whether this experimental intervention might help patients with brain tumors who volunteer to test this new agent.
This is a Phase I study to determine the maximum tolerated dose (MTD) and/or recommended phase II dose of D2C7-IT (D2C7 Immunotoxin) when delivered intratumorally by convection-enhanced delivery (CED) to recurrent World Health Organization (WHO) grade III and IV malignant glioma patients, and/or to determine what dose will be considered in a Phase II trial. Patients with recurrent WHO grade III and IV malignant glioma who meet eligibility criteria will be enrolled into the study. Immediately following the stereotactically-guided tumor biopsy conducted as standard of care, up to three additional core biopsies will be obtained for molecular genetic testing. After these biopsies are obtained, subjects will have up to 2 catheters inserted. If the biopsy indicates a proven diagnosis of recurrent malignant glioma (diagnosis results are typically received within 24-48 hours following biopsy), the investigators will proceed with the D2C7-IT infusion. If no tumor is identified, the catheters will be removed. A continuous intratumoral infusion of D2C7-IT will be administered over 72 hours while in the hospital.
The purpose of this study is to test the effectiveness of a drug called temsirolimus in combination with a drug called perifosine in treating brain tumors that have continued to grow after previous treatment. Temsirolimus is an intravenous drug approved by the FDA for treatment of other cancers (kidney cancer, certain types of lymphoma) but not for brain tumors. Perifosine is a pill that has not been approved by the FDA which blocks a messenger that tells cancer cells to grow. Research suggests that combined treatment with both drugs is better than either alone, and that it is reasonably safe.
