MicroRNAs (miRNA) are molecular biomarkers that post-transcriptionally control target genes. Deregulated miRNA expression has been observed in diverse cancers. In high grade gliomas, known as glioblastomas, the investigators have identified an oncogenic miRNA, miRNA-10b (mir-10b) that is expressed at higher levels in glioblastomas than in normal brain tissue. This study tests the hypothesis that in primary glioma samples mir-10b expression patterns will serve as a prognostic and diagnostic marker. This study will also characterize the phenotypic and genotypic diversity of glioma subclasses. Furthermore, considering the critical function of anti-mir-10b in blocking...
Objective: This protocol is designed to allow evaluation of participants neurosurgical disorders that receive care within the Surgical Neurology Branch. The participants will receive standard-of-clinical-care evaluation and treatment. The clinical data and samples generated during standard of care treatment will be collected as a part of this study. Study Population: Participants 4 years of age and older with neurosurgical-related conditions seeking care from, or referred to the Surgical Neurology Branch for evaluation are eligible for this protocol. Study Design: This is an observational study. Participants will receive standard-of- clinical-care evaluation and treatment for...
Background: The National Cancer Institute Surgery Branch (NCI-SB) has developed experimental therapies that involve taking white blood cells from patients' tumor or from their blood, growing them in the laboratory in large numbers, and then giving the cells back to the patient. Objective: This study will allow patients to under screening and evaluation for participation in NC-SB Protocols. Eligibility: Patients 18 years or older must meet the minimum eligibility criteria for an NCI-SB treatment protocol. Design Patients will undergo testing and evaluations as required by the appropriate NCI-SB treatment protocol.
The purpose of this study is to see if 18F-Fluciclovine (Axumin®) is useful and safe in the management of children with Low Grade Gliomas (LGG). Imaging with 18F-Fluciclovine PET-MRI will be performed prior to initiation of therapy for LGG, and then 3 months, and 1 year after starting therapy. Changes in 18F-Fluciclovine uptake will be compared to changes in MRI measurements at 3 months and 1 year as compared to baseline.
This study investigates the uptake of the radiopharmaceutical 68-GaNOTA-Anti-HER2 VHH1 in brain metastasis using PET/CT imaging. Patients with HER2-positive and HER2-negative cancer will be included and the uptake in their lesions will be compared. Optional 68-GaNOTA-Anti-HER2 VHH1 scans may be performed during or after treatment, at time points 12±6 weeks and 24±9 weeks after the first scan.
This study explores the role of T cells in monitoring disease status and response during anti-PD-1/PD-L1 treatment in patients with melanoma, lung and other cancer types. Measuring levels of specific targets such as Bim and soluble PD-L1 during therapy may help track treatment resistance and clinical outcomes. This information may also help researchers determine why some people with melanoma, lung and other cancer types respond to PD-1/PD-L1 treatment and others do not.
A multicentre randomised controlled trial (RCT) will be conducted to evaluate the effectiveness of the digital personalised Melanoma Survivorship Care Plan (SCP) app. A total of hundred-eighty melanoma patients (stage I and II) will be randomised to receive either the SCP Melanoma app or usual care. The app provides survivors with personalized healthcare information on diagnosis, treatment and follow-up and supportive care, tailored to their melanoma stage and phase and information needs.Through questionnaires, medical file records, patient-reported outcomes and use of medical care will be evaluated. In addition, log-data, questionnaires and interviews will be used to evaluate the...
Background: The presence of T-lymphocytes in resected tumor samples derived from long-term survival patients and the fact that reinvigoration of their functionality through the administration of specific immune-therapies can lead to remarkable antitumor responses supports that lymphocytes play a critical role in cancer immunity. TIL-based ACT (Adoptive cell therapy using tumor-infiltrating lymphocytes product) is a modality of ACT used to treat patients with multiple types of cancer and it consists in the adoptive transfer of ex vivo expanded autologous tumor-infiltrating lymphocytes obtained from tumor resection or tumor biopsies in patients following a...
The study is aimed at assessing changes in the brain of patients from 6 to 18 years old with a diagnosis of acute lymphoblastic leukemia during chemotherapy.
Dental caries affects billions of people worldwide and involves saliva immunodeficiency, commensal pathogen and exposure (lifestyle) causal subtypes of the disease. Up to 85% of adolescents in Swedish and other low prevalence populations are caries-free while the remaining 15% show high, recurrent caries activity. Accordingly, there is a lack of cost-effective risk assessment and prevention tools for personalized oral care. This randomized adaptive clinical trial (RCT) evaluates both caries prevention based on genetic etiology and risk, as a consequence of saliva immunodeficiency genes specifying individuals as susceptible or resistant to caries, and the effect of intensified...
