The researchers are doing this study to find out how effective sotorasib is at getting into KRAS G12C+ brain tumors. The researchers will also find out whether sotorasib is a safe and effective treatment for people undergoing surgical resection of KRAS G12C+ metastatic brain tumors, and do tests that show how the body absorbs, distributes, and gets rid of sotorasib.
This study seeks to investigate an evidence-based, manualized, behavioral health intervention, Cognitive Behavioral Therapy for Insomnia (CBT-I), in individuals with primary brain tumors (PBT) and insomnia. Our project will assess the feasibility and acceptability of recruitment, enrollment, data collection procedures, and retention of individuals with PBT and insomnia in the behavioral health intervention, CBT-I, and investigate the potential benefits of CBT-I within this at-risk and understudied population. In the long term, the goals are to expand treatment options for neuro-oncology patients and improve their mission readiness and overall wellbeing.
This is an open-label phase 1 safety and feasibility study that will employ multi-tumor antigen specific cytotoxic T lymphocytes (TSA-T) directed against proteogenomically determined personalized tumor-specific antigens (TSA) derived from a patient's primary brain tumor tissues. Young patients with embryonal central nervous system (CNS) malignancies typically are unable to receive irradiation due to significant adverse effects and are treated with intensive chemotherapy followed by autologous stem cell rescue; however, despite intensive therapy, many of these patients relapse. In this study, individualized TSA-T cells will be generated against proteogenomically determined tumor-specific antigens after standard of care treatment in children less than 5 years of age with embryonal brain tumors. Correlative biological studies will measure clinical anti-tumor, immunological and biomarker effects.
Recent advances in technology have allowed for the detection of cell-free DNA (cfDNA). cfDNA is tumor DNA that can be found in the fluid that surrounds the brain and spinal cord (called cerebrospinal fluid or CSF) and in the blood of patients with brain tumors. The detection of cfDNA in blood and CSF is known as a "liquid biopsy" and is non-invasive, meaning it does not require a surgery or biopsy of tumor tissue. Multiple studies in other cancer types have shown that cfDNA can be used for diagnosis, to monitor disease response to treatment, and to understand the genetic changes that occur in brain tumors over time. Study doctors hope that by studying these tests in pediatric brain tumor patients, they will be able to use liquid biopsy in place of tests that have more risks for patients, like surgery. There is no treatment provided on this study. Patients who have CSF samples taken as part of regular care will be asked to provide extra samples for this study. The study doctor will collect a minimum of one extra tube of CSF (about 1 teaspoon or 5 mL) for this study. If the patients doctor thinks it is safe, up to 2 tubes of CSF (about 4 teaspoons or up to 20 mL) may be collected. CSF will be collected through the indwelling catheter device or through a needle inserted into the lower part of the patient's spine (known as a spinal tap or lumbar puncture). A required blood sample (about ½ a teaspoon or 2 3 mL) will be collected once at the start of the study. This sample will be used to help determine changes found in the CSF. Blood will be collected from the patient's central line or arm as a part of regular care. An optional tumor tissue if obtained within 8 weeks of CSF collection will be collected if available. Similarities between changes in the DNA of the tissue that has caused the tumor to form and grow with the cfDNA from CSF will be compared. This will help understand if CSF can be used instead of tumor tissue for diagnosis. Up to 300 people will take part in this study. This study will use genetic tests that may identify changes in the genes in the CSF. The report of the somatic mutations (the mutations that are found in the tumor only) will become part of the medical record. The results of the cfDNA sequencing will be shared with the patient. The study doctor will discuss what the results mean for the patient and patient's diagnosis and treatment. Looking for inheritable mutations in normal cells (blood) is not the purpose of this study. Genetic tests of normal blood can reveal information about the patient and also about the their relatives. The doctor will discuss what the tests results may mean for the patient and the their family. Patient may be monitored on this study for up to 5 years.
The objective of the International Rare Brain Tumor Registry (IRBTR) is to better understand rare brain tumors through the collection of biospecimens and matched clinical data of children, adolescents, and young adult patients diagnosed with rare brain tumors.
Recent lab-based discoveries suggest that IDO (indoleamine 2,3-dioxygenase) and BTK (Bruton's tyrosine Kinase) form a closely linked metabolic checkpoint in tumor-associated antigen-presenting cells. The central clinical hypothesis for the GCC2020 study is that combining ibrutinib (BTK-inhibitor) with indoximod (IDO-inhibitor) during chemotherapy will synergistically enhance anti-tumor immune responses, leading to improvement in clinical response with manageable overlapping toxicity. GCC2020 is a prospective open-label phase 1 trial to determine the best safe dose of ibrutinib to use in combination with a previously studied chemo-immunotherapy regimen, comprised of the IDO-inhibitor indoximod plus oral metronomic cyclophosphamide and etoposide (4-drug combination) for participants, age 6 to 25 years, with relapsed or refractory primary brain cancer. Those previously treated with indoximod plus temozolomide may be eligible, including prior treatment via the phase 2 indoximod study (GCC1949, NCT04049669), the now closed phase 1 study (NLG2105, NCT02502708), or any expanded access (compassionate use) protocols. A dose-escalation cohort will determine the best safe dose of ibrutinib for the 4-drug combination. This will be followed by an expansion cohort, using ibrutinib at the best safe dose in the 4-drug combination, to allow assessment of preliminary evidence of efficacy.
Indoximod was developed to inhibit the IDO (indoleamine 2,3-dioxygenase) enzymatic pathway, which is important in the natural regulation of immune responses. This potent immune suppressive mechanism has been implicated in regulating immune responses in settings as diverse as infection, tissue/organ transplant, autoimmunity, and cancer. By inhibiting the IDO pathway, we hypothesize that indoximod will improve antitumor immune responses and thereby slow the growth of tumors. The central clinical hypothesis for the GCC1949 study is that inhibiting the pivotal IDO pathway by adding indoximod immunotherapy during chemotherapy and/or radiation is a potent approach for breaking immune tolerance to pediatric tumors that will improve outcomes, relative to standard therapy alone. This is an NCI-funded (R01 CA229646, MPI: Johnson and Munn) open-label phase 2 trial using indoximod-based combination chemo-radio-immunotherapy for treatment of patients age 3 to 21 years who have progressive brain cancer (glioblastoma, medulloblastoma, or ependymoma), or newly-diagnosed diffuse intrinsic pontine glioma (DIPG). Statistical analysis will stratify patients based on whether their treatment plan includes up-front radiation (or proton) therapy in combination with indoximod. Central review of tissue diagnosis from prior surgery is required, except non-biopsied DIPG. This study will use the "immune-adapted Response Assessment for Neuro-Oncology" (iRANO) criteria for measurement of outcomes. Planned enrollment is up to 140 patients.
SJELIOT is a phase 1 trial that aims to explore the combination of prexasertib with established DNA-damaging agents used in medulloblastoma to evaluate tolerance and pharmacokinetics in recurrent or refractory disease. Additionally, a small expansion cohort will be incorporated into the trial at the combination MTD/RP2D (maximum tolerated dose/recommended phase two dose) to detect a preliminary efficacy signal. Stratum A: Prexasertib and Cyclophosphamide Primary Objectives * To determine the safety and tolerability and estimate the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of combination treatment with prexasertib and cyclophosphamide in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma and recurrent/refractory sonic hedgehog (SHH) medulloblastoma. * To characterize the pharmacokinetics of prexasertib in combination with cyclophosphamide. Secondary Objectives * To estimate the rate and duration of objective response and progression free survival (PFS) associated with prexasertib and cyclophosphamide treatment in this patient population. * To characterize the pharmacokinetics of cyclophosphamide and metabolites. Stratum B: Prexasertib and Gemcitabine Primary Objectives * To determine the safety and tolerability and estimate the MTD/RP2D of combination treatment with prexasertib and gemcitabine in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma. * To characterize the pharmacokinetics of prexasertib in combination with gemcitabine. Secondary Objectives * To estimate the rate and duration of objective response and PFS associated with prexasertib and gemcitabine treatment in this patient population. * To characterize the pharmacokinetics of gemcitabine and gemcitabine triphosphate (only at St. Jude Children's Research Hospital).
Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES: * To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum. * To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE: * To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.
This phase I trial studies the side effects and best dose of ribociclib and everolimus and to see how well they work in treating patients with malignant brain tumors that have come back or do not respond to treatment. Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as everolimus, 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 ribociclib and everolimus may work better at treating malignant brain tumors.
The purpose of this study is to test any good and bad effects of a study drug called abemaciclib (LY2835219) in patients with recurrent brain tumors.
This is a first-in-children phase 1 trial using indoximod, an inhibitor of the immune "checkpoint" pathway indoleamine 2,3-dioxygenase (IDO), in combination with temozolomide-based therapy to treat pediatric brain tumors. Using a preclinical glioblastoma model, it was recently shown that adding IDO-blocking drugs to temozolomide plus radiation significantly enhanced survival by driving a vigorous, tumordirected inflammatory response. This data provided the rationale for the companion adult phase 1 trial using indoximod (IND#120813) plus temozolomide to treat adults with glioblastoma, which is currently open (NCT02052648). The goal of this pediatric study is to bring IDO-based immunotherapy into the clinic for children with brain tumors. This study will provide a foundation for future pediatric trials testing indoximod combined with radiation and temozolomide in the up-front setting for patients with newly diagnosed central nervous system tumors.
This pilot clinical trial study will assess the inflammatory response of brain tumors or other central nervous system conditions in pediatric and adult patients using ferumoxytol-enhanced MRI. Imaging features will be correlated with the number of inflammatory cells (macrophages) at histopathology. Determining the extent of inflammation associated with pathologies in the central nervous system may be helpful for diagnostic and prognostic purposes as well as monitoring treatment response of current and future immunotherapies.
Glioblastoma (GBM) and gliosarcoma (GS) are the most common and aggressive forms of malignant primary brain tumor in adults and can be resistant to conventional therapies. The purpose of this Phase Ib study is to evaluate how well a recurrent glioblastoma or gliosarcoma tumor responds to one injection of DNX-2401, a genetically modified, conditionally replicative and oncolytic human-derived adenovirus. DNX-2401 is delivered directly into the tumor where it may establish an active infection by replicating in and killing tumor cells.
DM-CHOC-PEN is a polychlorinated pyridine cholesteryl carbonate that has demonstrated antineoplastic activities in patients with advanced cancers - melanoma, lung, breast and glioblastoma multiforme (GBM) involving the CNS during a Phase I study. These findings support the preclinical responses seen in mice bearing intracerebrally implanted human breast and GBM tumor xenografts. Toxicity was acceptable - hyperbilirubinemia (in patients with liver disease and/or liver metastasis). No hematological, renal, cardiovascular, behavioral or cognitive impairment/neurotoxicities were noted during the Phase I human trial or in previous pre-clinical studies. The drug is available for use as a soy bean oil/egg yolk lecithin/glycerin water emulsion; the latter continues to be chemically and biologically stable and safe. Patients with advanced lung, breast and melanoma cancers spread to the CNS and primary CNS malignancies will be eligible for enrollment and treatment, providing the required blood and other eligibility requirements are met. The trial will be 2-tiered - patients with liver involvement vs. non-liver involvement will be treated with different doses of the drug. The trial is open and patients are currently being enrolled and treated with the protocol.
The goal of this proposal is to evaluate a new Photodynamic Therapy (PDT) modification which could revolutionize the treatment of brain tumors in children and adults. There are currently few cases published involving the use of PDT in infratentorial (in the posterior fossa) brain tumors in general and specifically those occurring in children. The investigators propose to test a technique, for the first time in the U.S., that demonstrated in Australian adult glioblastoma patients dramatic long-term, survival rates of 57% (anaplastic astrocytoma) and 37% (glioblastoma multiforme). These results are unprecedented in any other treatment protocol. Photodynamic therapy (PDT) is a paradigm shift in the treatment of tumors from the traditional resection and systemic chemotherapy methods. The principle behind photodynamic therapy is light-mediated activation of a photosensitizer that is selectively accumulated in the target tissue, causing tumor cell destruction through singlet oxygen production. Therefore, the photosensitizer is considered to be the first critical element in PDT procedures, and the activation procedure is the second step. The methodology used in this proposal utilizes more intensive laser light and larger Photofrin photosensitizer doses than prior PDT protocols in the U.S. for brain tumor patients. The PDT will consist of photoillumination at 630 nm beginning at the center of the tumor resection cavity, and delivering a total energy of 240 J cm-2. The investigators feel that the light should penetrate far enough into the tissue to reach migrating tumor cells, and destroy these cells without harming the healthy cells in which they are dispersed. The investigators will be testing the hypothesis that pediatric subjects with progressive/recurrent malignant brain tumors undergoing PDT with increased doses of Photofrin® and light energy than were used in our previous clinical study will show better progression free survival (PFS) and overall survival (OS) outcomes. PDT will also be effective against infratentorial tumors. The specific aims include determining the maximum tolerable dose (MTD) of Photofrin in children and looking for preliminary effectiveness trends.
Background: - An important new area of brain tumor research is the development of tumor and brain stem cell lines. Successful growth of these cell lines requires obtaining large volumes of fresh tumor and brain tissue, which is best accomplished by harvesting whole brains from recently deceased patients. These cell lines will help researchers understand how these tumors develop and will also help identify new targets for treatment. Researchers are interested in conducting a pilot study of planned inpatient hospice care with timely brain tumor tissue harvest at the time of death. Objectives: * To provide high-quality end of life inpatient hospice care for patients with untreatable brain tumors. * To procure brain and tumor tissue shortly after time of death in order to derive viable tumor and neural stem cell lines for research purposes. Eligibility: * Individuals at least 18 years of age who have an untreatable primary brain or central nervous system tumor, are able to give informed consent (either their own or through a designated power of attorney), and have agreed to a Do Not Resuscitate order and Consent for Autopsy as part of the end-of-life care plan. * HIV-positive individuals or those suspected of having infectious cerebritis are not eligible because of the potential for contamination of brain tissue. Design: * Participants will be enrolled in inpatient hospice admission to the National Institutes of Health Clinical Center either from home or from an outside hospital once a study investigator estimates an expected survival of less than 2 weeks. * Participants will receive palliative care at the Clinical Center. Care will be tailored to each participant depending on the information provided in the individual's end-of-life care plan. * Supportive medications such as antiseizure medications and pain relievers will be administered as appropriate. * At the time of death, researchers will follow standard procedures for notifying next of kin and will collect brain tissue and tumor samples from the deceased. * Following tissue collection, the deceased will be released for autopsy and funeral procedures.
The aim of this study is to follow up with all of the pediatric brain tumor patients who received proton beam radiation therapy at Massachusetts General Hospital (MGH) for which there is baseline neuropsychological testing in order to measure changes, if any, in neurobehavioral functioning (executive skills, emotional/behavioral functioning, and adaptive abilities) and their use of special education services at one year or more post-treatment. The investigators will also correlate neurobehavioral data with pertinent clinical information. Participation will be maximized through the use of mail-in, parental- and self-report questionnaires.
In recent years, remarkable advances in medical oncology, surgery, and radiology have allowed for increasing cure rates for childhood malignancies. This success has led to an emerging understanding of the kinds of effects that treatments can have on the pediatric population and how such effects can influence pediatric cancer survivor's functioning and quality of life. It has become tremendously important to assess the long-term complications due to therapy in this growing sector of survivors and to tailor our treatments so as to minimize these late effects. The Investigators at MGH are committed to improving the delivery of radiotherapy to our patients and improving the outcome for these patients. MGH has an on-site cyclotron for proton radiotherapy in order to provide the most advanced care for patients in need. Proton therapy possesses a clinical advantage over standard photon therapy in that its optimal dose distribution delivers the bulk of radiation to the tumor site. This method spares the greatest volume of normal tissue, resulting in decreased short-term and long-term morbidity. Through open pediatric protocols for patients treated with proton radiotherapy, the investigators aim to define and report the acute and late effects associated with treatment. The investigators also treat a number of patients off-protocol with both proton and photon radiotherapy, and are interested in reporting these patients' QOL outcomes in conjunction with other clinical data that may be pertinent to the site of tumor treatment. This research is significant in that it will allow us to delineate the positive and negative effects of radiation treatment on patients' QOL, highlighting points of success and exposing areas that are in need of improvement. Such knowledge will be used to improve the experience of pediatric cancer survivors in the future. The aims of this study are: 1) to prospectively collect and report the QOL outcomes in patients treated with radiotherapy and 2) to correlate the QOL data with pertinent clinical information.
The purpose of this study is to use an imaging method called functional magnetic resonance imaging (fMRI) in patients who have a tumor near an area of the brain that is believed to control language. The fMRI is a new kind of imaging that uses a strong magnetic field to look at functioning brain tissue. This kind of imaging will be used to study the effect of the brain tumor on your speech.
This research protocol makes pictures of brain tumors. The pictures are made with a positron emission tomography (PET) scanner. PET scans use radioactivity to "see" cancer cells. We are using a new kind of PET scan. The new PET scan is called \[18F\]-FACBC PET. We will compare this to the standard PET scan. The standard PET scan is called \[11C\]-methionine PET. We expect these pictures will give us information about your tumor. We also hope to collect information about the amount of radioactivity exposure. We will measure radioactivity exposure to your tumor, brain and other organs. The research study results will be used to support the submission of an investigational new drug (IND) application to the Food and Drug Administration (FDA).
A significant number of brain tumor patients who received radiation or chemotherapy have thinking problems as a result of their treatment. The purpose of this study is to find out if treatment with Aricept (donepezil) may improve some aspects of thinking abilities in patients with brain tumors who received radiation or chemotherapy. This research will also study whether persons having particular genes for a blood-borne substance called apolipoprotein E (APOE) are more likely to have thinking problems after radiation or chemotherapy treatment for their brain tumors. The findings of this study will help us find out whether Aricept can improve thinking abilities after cancer treatment, and whether some of the thinking difficulties may be in part related to having certain genes.
The purpose of this study is to: Find out how safe and effective (by monitoring the good and/or bad effects) treatment with high dose temozolomide, thiotepa and carboplatin with stem cell rescue followed by 13-cis-retinoic acid has on children and adolescents with recurrent/refractory brain tumors Find out how the body uses 13-cis-retinoic acid by studying the your blood levels and proteins in the blood that break down the 13-cis-retinoic acid Determine how well 13-cis-retinoic acid penetrates into the spinal fluid.
Bevacizumab may reduce CNS side effects caused by radiation therapy. This randomized phase II trial is studying how well bevacizumab works in reducing CNS side effects in patients who have undergone radiation therapy to the brain for primary brain tumor, meningioma, or head and neck cancer.
This phase I trial tests the safety, side effects and best dose of AdV-HSV1-TK and AdV-Flt3L in combination with valacyclovir for the treatment of patients with primary cancerous (malignant) brain tumors that can be removed by surgery (resectable) and that have come back after a period of improvement (recurrent). AdV-HSV1-TK and AdV-Flt3L use a virus modified in the laboratory to kill tumor cells and stimulate the immune system to recognize the tumor cells as "invaders" which can lead to tumor shrinkage. For this process to work, an oral anti-herpes medication called valacyclovir is also needed. Giving AdV-HSV1-TK, AdV-Flt3L and valacyclovir may be safe, tolerable and/or effective in treating patients with resectable, recurrent primary malignant brain tumors.
This clinical trial focuses on pediatric patients aged 2 up to 18 years of age with a new or recurrent pediatric brain tumor, suspected to be either a high-grade or low-grade glioma, and scheduled for surgical removal. 5-aminolevulinic acid (5-ALA) is FDA-approved for improving brain tumor visualization in adults during surgery through fluorescence, enabling more complete removal of the tumor. This study aims to evaluate the feasibility of administering 5-ALA to pediatric brain tumor patients and to assess the quality of tumor fluorescence during surgery in this patient population. For the clinical trial, the patient will orally ingest 5-ALA 6 to 12 hours before brain surgery. All study participants will be provided standard medical care for removal of the brain tumor. All children enrolled in the study will be closely monitored prior to, during, and after surgery to ensure there are no reactions to the study drug. 5-ALA can make the patient more sensitive to sunlight and direct indoor lighting, referred to as photosensitivity, and can cause a sunburn-type reaction. It is for this reason that patients will be kept in subdued light conditions for 48 hours following surgery. Study participation starts once the patient is enrolled in the study until 6-month post-surgery.
This clinical trial evaluates the impact of a research intervention of virtually supervised exercise program (RISE) on cancer-related cognitive impairment (CRCI), physical activity in adolescent and young adult (AYA) brain tumor survivors. This clinical trial also evaluates the impact of RISE on the collection of microorganisms that exist in the intestines (gut microbiome). Up to 45% of AYA brain tumor survivors experience CRCI, including issues with attention and memory. CRCI can have a negative impact on education, independent living and can worsen long-term quality of life. Moderate-intensity levels of exercise, particularly aerobic and resistance training, have been shown to improve cognitive function. Additionally, exercise can change the composition and function of the gut microbiome, which may lead to improved cognitive function. Unfortunately, only about 50% of AYAs with cancer receive exercise information or meet the physical activity recommendations. Tailoring a virtually delivered exercise intervention to meet the unique needs of AYAs may improve access to exercise. Participating in the virtual home-based exercise intervention, RISE, may improve physical activity and cognitive impairment in AYA brain tumor survivors and may also help researchers understand the relationship of exercise on the gut microbiome and cognitive function.
This phase II trial studies how well the addition of 18F-DOPA (amino acid) positron emission tomography (PET)/computed tomography (CT) to standard of care (SOC) imaging can improve the clinical management of patients with brain tumors in over 50% of cases. PET is an imaging test that helps to measure the information about functions of tissues and organs within the body. A PET scan uses a radioactive drug (radiotracer) to show this activity. CT scan uses X-rays to create images of the bones and internal organs within the body. Combining a PET scan with a CT scan can help make the images easier to interpret. PET/CT scans are hybrid scanners that combine both of the two modalities into a single scan. This allows images of both anatomy (CT) and function (PET) to be taken during the same scan. The 18F-DOPA PET/CT scan is done with a very small amount of a radioactive tracer called FDOPA. The PET/CT scan is then used to detect the location of tumors. Using the 18FDOPA-PET/CT scan in addition to the SOC scan may improve the clinical management of patients with brain tumors.
This phase I trial studies how well zirconium (Zr)-89 crefmirlimab berdoxam and immuno-positron emission tomography (PET) identifies areas of immune cell activity in patients with brain tumors that can be removed by surgery (resectable). One important predictor of the immune response is the presence and change in CD8 positive (+) tumor infiltrating lymphocytes (TIL) cells. Identifying the presence and changes in CD8+ cells can be challenging, particularly for participants with central nervous system (CNS) tumors, and usually requires invasive procedures such as repeat tissue biopsies, which may not accurately represent the immune status of the entire tumor. Zr-89 crefmirlimab berdoxam is known as a radioimmunoconjugate which consists of a radiolabeled anti-CD8+ minibody whose uptake can be imaged with PET. Upon administration, Zr 89 crefmirlimab berdoxam specifically targets and binds to the CD8+ cells. This enables PET imaging and may detect CD8+ T-cell distribution and activity and may help determine the patient's response to cancer immunotherapeutic agents more accurately. Giving Zr-89 crefmirlimab berdoxam along with undergoing immuno-PET imaging may work better at identifying immune cell activity in patients with resectable brain tumors.
Nearly 23,000 adults are diagnosed with primary central nervous system (CNS) malignancy yearly. An additional 200,000 adults are diagnosed with brain metastasis. There are significant variations in CNS tumor treatment. However, due to significant heterogeneity in patient baseline factors, identifying unwarranted variation is challenging. Ghogawala et al have previously demonstrated that, among patients undergoing surgical treatment of cervical myelopathy and lumbar degenerative spinal disease, an expert panel consisting of surgeon experts can identify variations in proposed surgical procedure and demonstrated superior patient outcomes when the surgery performed matched the procedure recommended by expert consensus. Expert panel surveys have not previously been used to identify variations in care among patients with CNS malignancy. The primary aim is to determine whether patient outcomes are superior when treatment aligns with recommendations made by a clinical expert neurosurgical panel. The study also seek to identify patient factors that predispose to variability in care. Our long-term aim is to determine whether predictive artificial learning algorithms can achieve the same outcomes, or better, as clinical expert panels, but with greater efficiency and greater capacity to be available for more patients. The investigators hypothesize that: * When a team of 10 medical experts has greater than 80% consensus regarding optimal treatment and when the doctor and patient select that specific treatment, the outcome is superior than when a patient and doctor select an alternative procedure. * When a team of 10 medical experts has greater than 80% consensus regarding optimal treatment, the structured data used by the experts can be processed and trained by computing algorithms to predict the pattern recognized by the experts - i.e. - the computer can predict how an expert panel would vote. Procedures include the following: 1. Chart review portion of study: Patients will be identified from case logs of the principal investigators from July 2017 through July 2023. Data will be collected retrospectively and will include age, non-identifier demographics, diagnosis details, operative/treatment characteristics, post-treatment characteristics, and follow-up characteristics. Images reviewed will include pre and post-treatment MRIs obtained as part of routine care. Data will be abstracted from the medical record (Epic/Soarian and PACS) and recorded in an excel database. 2. Survey portion of study: De-identified structured radiographic data and a brief clinical vignette without patient identifiers will be uploaded to Acesis Healthcare Process Optimization Platform (http://www.acesis.com/our-platform). A survey will be generated by Acesis and emailed to the subject experts/participants. This portion is prospective. 3. Cohort definitions: 1. Patients will be assigned to either "expert-treatment consensus" or "no expert-treatment consensus" arms based on whether greater than 80% consensus is achieved 2. Patients will be assigned to either "Expert consensus-aligned" or "Expert consensus - unaligned" arms based on whether expert survey results match actual treatment given. 4. Data will then be analyzed using appropriate packages with SAS statistical analysis software. Survival analysis will be performed to determine whether consensus predicts improved progression free survival (PFS). 5. The structured and de-identified radiographic images used by the experts in surveys will be used for training and development of an AI algorithm. The aim of this portion of the study is to determine whether standardized and structured imaging can be used to train an algorithm to predict whether expert consensus is achieved and the recommended treatment.
