20-40% of patients with NSCLC will develop brain metastases at some point during their course of disease. Osimertinib has demonstrated intracranial activity in EFGR mutated NSCLC with leptomeningeal disease in the phase 1 BLOOM study. Stereotactic radiosurgery (SRS) is one of the standard local treatment for patients with limited number of brain metastases. Currently, it is unclear whether adding SRS to Osimertinib will result in superior intracranial disease control in patients with EGFR mutated NSCLC with brain metastases diagnosed de novo or developed while on first line EGFR tyrosine kinase inhibitors (TKIs) such as Erlotinib and ...
CNS tumor requires biopsy for pathological diagnosis, which is known as the "golden standard". We would like to achieve automated classification of brain tumors based on deep learning in digital histopathology images and molecular pathology results. We expect to develop an assistant system (including software and hardware), to help pathologists during their diagnosis for CNS tumor.
A Phase 2 Study of ARX788 in HER2-positive, Metastatic Breast Cancer Patients whose Disease is resistant or refractory to Tyrosine kinase inhibitors (TKI).
The aim of this study was to evaluate the progression time and efficacy of brain tumors in patients with brain metastases from HER2-positive breast cancer treated with Pyrrolidine and Capecitabine combined with brain radiotherapy.
Purpose of the study: AIM 1 Prospectively collect pre-operative (fMRI, DTI, MEG) and intra-operative mapping data in patients with intra-axial brain tumors to assess how well each modality predicts the location of eloquent brain function. In addition, each modality will be compared with the other. AIM 2 Assess reorganization of eloquent brain function and plasticity in patients with intra-axial brain tumors. This will be accomplished by prospectively collecting post-operative mapping studies and neuropsychological tests to compare them to prior mapping studies as stated above.
This trial gathers information from patients with primary central nervous system or base of skull tumors that receive proton beam therapy and see if certain imaging techniques can help detect radiation-related changes over time. This study may help providers learn more about proton beam radiotherapy and how to improve the way it is delivered.
This phase II trial studies the neurological function in patients with multiple brain metastases undergoing stereotactic radiosurgery (SRS) or stereotactic body radiation therapy (SBRT). Assessment of neurocognitive function may help show that SRS preserves neurological function in patients with multiple brain metastases better than SBRT
Purpose of Study This exploratory clinical study will investigate FMISO (fluoromisonidazole) in patients with (1) newly diagnosed primary malignant brain tumors (WHO [World Health Organization] Grade III or IV glial-based tumors) who have not had a complete surgical resection and by contrast MRI (Magnetic resonance imaging) have residual tumor > 1.0 cm in diameter and will be receiving radiotherapy or (2) newly diagnosed brain metastasis (> 1.0 cm in diameter who will be receiving radiotherapy. The ability to accurately assess tumor hypoxia and accurately determine the amount/degree of tumor hypoxia could potentially change patient...
The spread of cancer to the brain is referred to as brain metastases. Brain metastases are a common complication of cancer. This study is being done to determine whether the use of a new imaging agent, 18F-fluciclovine, is able to detect which patients are responding to radiation therapy. In addition, this study will look at the changes of the treated brain metastases using this imaging agent over time.
This study will evaluate the safety, pharmacokinetics, and efficacy of alectinib in children and adolescents with ALK fusion-positive solid or CNS tumors for whom prior treatment has proven to be ineffective or for whom there is no satisfactory standard treatment available.
