The growing U.S. cancer survivor population is projected to hit 26M by 2040. Chemotherapy represents an effective cancer treatment but can diminish cancer survivors' quality of life-particularly cognitive function-through select pathophysiological processes. Research on chemotherapy-induced cognitive impairment (hereafter, 'chemo-brain') is therefore critical. Chemotherapy disrupts immune system function and antioxidant regulation, causing inflammatory molecule release and damaging the brain's blood vessels. The brain's vascular function and, possibly, its neurons, are subsequently impaired-likely contributing to chemo-brain. Type 2 diabetes (T2D), a common cancer survivor...
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain...
Primary brain cancer kills up to 10,000 Americans a year. These 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. The investigators have completed a Phase I clinical trial that has shown that Superselective Intraarterial Cerebral Infusion (SIACI)...
This is a phase 2a, randomized, double-blinded, placebo-controlled pilot clinical trial determining the impact of riluzole therapy on circulating brain derived neuropathic factor (BDNF) levels of breast cancer survivors with cancer related cognitive impairment.
This trial is a paucicentric, clinico-biological cohort study with retrospective and prospective enrollment, aiming to identify biomarkers predictive of response to Proton Beam Therapy (PBT) in cancer patients (high grade sarcoma, brain tumors and meningioma). This study include collection of clinical data, of tumor samples (collected during standard of care) and a blood sample for alive patients.
Glioblastoma is the most common primary malignancy of the central nervous system with a very poor prognosis. Most of the immunotherapies that have made significant breakthroughs in the treatment of other tumors in recent years are unsatisfactory in the application of glioblastoma, which is mainly inseparable from the highly inhibitory immune microenvironment formed by the latter. Therefore, how to change this "immune desert" and better activate immune effector cells to play an anti-tumor effect is currently a hot spot in glioma immune research. In recent years, there has been continuous research support that the myeloid cells of the central nervous system are partly derived from...
This study is to evaluate the efficacy and tolerability of surgery in selecting patients who can benefit from the synchronous resection of primary pancreatic neuroendocrine tumor and liver metastasis after induction systemic treatment. The willing of participants decide who receive surgery and who will continue to receive standard systemic treatment.
The goal of the study is to investigate whether treating insomnia using app-based cognitive behavioral therapy for insomnia (CBT-I) can improve cognitive impairment in breast cancer survivors compared to an active control group (sleep hygiene education). The study will also explore if CBT-I is associated with changes in the brain and in inflammation. The investigators will recruit approximately 84 participants with insomnia and cognitive impairment who have completed breast cancer treatment within 1-5 years.
The study seeks to assess the response of glioblastoma multiforme to treatment using weekly low field (0.35 T) MR-images of the brain at a MRIdian® linac system during standard radiotherapy at the same system. A total of 20 patients in a single arm will be recruited for this investigation. The imaging data will be used to evaluate the change in tumor volume over the course of the treatment and to perform radiomics in order to investigate the possibility of response prediction using these images. In order to assure sufficient image quality, prior to the main investigation, a group of up to 20 volunteers has MR scans taken with identical sequences to the main study phase.
The administration of steroids, most commonly dexamethasone (DEX), has established as standard of care during treatment of glioblastoma (GBM) and is widely used during the entire course of the disease including pre- and postoperative management, chemo- and radiotherapy. The primary purpose is to reduce tumor-associated vasogenic edema and to prevent or treat increased intracranial pressure. However, steroids are also linked to a multitude of adverse side effects that may affect survival of GBM patients such as major immunosuppression. The use of steroids during radiotherapy is associated with reduced overall- and progression-free survival and has been identified as an independent...
