In this research study the investigators want to learn more about an alternate, local treatment for skin schwannomas. Specifically, local doxycycline intra-tumoral injection will be performed as a potential treatment for NF2-related skin schwannomas, ultimately reducing the risks and costs associated with standard surgical removal of such skin tumors if successful.
The aim of this observational study, based on a prospectively collected cohort, is to evaluate the prognostic value of patient-derived organoids in predicting responses to conventional and repurposing drugs, including temozolomide, in patients with primary or recurrent glioblastoma. The primary question is whether the patient's response to temozolomide is recapitulated in their corresponding patient-derived glioblastoma organoid (GBO). Patient drug responses are evaluated using survival data, while GBO drug responses are assessed through a drug-response testing platform utilizing cell viability assays. Additionally, this platform is used to explore the potential application...
This phase II trial studies how well dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI) works in measuring relative cerebral blood volume (rCBV) for early response to bevacizumab in patients with glioblastoma that has come back. DSC-MRI may help evaluate changes in the blood vessels within the cancer to determine a patient?s response to treatment.
The primary goal of this registry is to increase the knowledge about spine tumors and other spine disorders to guide appropriate management strategies for the future. This registry will include the review of medical records, data collection for health related quality of life questionnaires, and collected tissues and samples. The study will require obtaining spinal lesions (tumor, etc.), blood, and bone marrow samples (from non-lesional bone) from selected patients, which will be collected during your surgery.
The purpose of this study is to compare the effects on patients with metastatic melanoma of taking a government approved and paid-for PD-1 inhibitor intermittently, with taking the same type of agent continuously. Researchers want to see if the two ways of giving this type of treatment work equally well in extending the life of patients with melanoma, or not.
A prospective multicenter, single-arm phase II study enrolling treatment-naïve patients with metastatic pulmonary large-cell neuroendocrine carcinoma (LCNEC)
This study is for patients with neuroendocrine tumours (NET) with or without carcinoid syndrome followed by NET Unit of European Institute of Oncology. The objective of the trial is to evaluate biochemical markers of myocardial injury (high-sensitive troponins), haemodyinamic markers (pro-brain natriuretic peptide (BNP), N-terminal (NT)-BNP (NT-proBNP)), and markers of fibrosis (Suppression of Tumorigenicity 2 (ST2) in patients with neuroendocrine tumours (NET) with or without carcinoid syndrome.
This is a prospective, multicenter, randomized, controlled clinical study of NSCLC patients with intracranial oligo-metastatic EGFR-sensitive mutations treated with EGFR-TKI Almonertinib , according to the implementation time of brain radiotherapy. Patients were randomly divided into two groups, experimental group (early intervention group of brain radiotherapy) : the brain radiotherapy started within 1 month of TKI treatment, the brain radiotherapy here specifically refers to stereotactic radiotherapy; Control group (brain radiotherapy late intervention group) : Brain radiotherapy was given within 3 months after brain progression during TKI treatment. The differences in...
The vestibulo-ocular reflex (VOR) induces a compensatory movement in the eye when the head is rotated, to maintain stable vision when we move. It originates in the peripheral vestibular system, which detects head movements. It is particularly effective for rapid head movements, as tested in the Head Impulse Test (HIT). In acute unilateral vestibular deficit (AUVD), the VOR deficit is compensated for by a substitution saccade, more commonly known as catch up saccade, that contribute to refocus the gaze and maintain vision during head rotations. Recent technological advances have made it possible to make high-quality recordings during HIT (video Head Impulse Test, vHIT), leading...
This is a multicenter, two-arm, randomized, double-blind, placebo-controlled study of Optune® (Tumor Treating Fields at 200 kHz) together with maintenance Temozolomide (TMZ) chemotherapy agent and pembrolizumab compared to Optune® together with maintenance TMZ and placebo in newly diagnosed Glioblastoma (GBM) patients. The primary objective of the study is to evaluate the Overall Survival (OS).
