Background: Glioblastoma (GBM) is a cancer of the brain. Current survival rates for people with GBM are poor; survival ranges from 5.2 months to 39 months. Most tumors come back within months or years after treatment, and when they do, they are worse: Overall survival drops to less than 10 months. No standard treatment exists for people whose GBM has returned after radiation therapy. Objective: To find a safe schedule for using radiation to treat GBM tumors that returned after initial radiation treatment. Eligibility: People aged 18 years and older with grade 4 GBM that returned after initial...
The goal of this prospective observational study is to evaluate the presence of circulating tumoral cells in patients over 18 with a stage I-III resectable Merkel cell carcinoma after the initial therapeutic sequence of surgery and radiotherapy. The main question it aims to answer is : Can any residual disease be found in the form of circulating tumoral cells in blood samples of patients treated with surgery and radiotherapy for a resectable, stage I to III Merkel cell carcinoma ? When possible, the circulating tumoral cells count will be compared to the one realized in a blood sample of the same patient before surgery and...
HER2 gene amplification, detected in 20% to 30% of breast cancers, was a poor prognostic factor before the advent of anti-HER2 therapies. In the early 2000s, trastuzumab revolutionised the management of patients with HER2-positive (HER2+) breast cancer in the metastatic and localised stages of the disease. At the time of diagnosis of metastatic disease, 7-11% of patients have brain metastases, with (70% of cases) or without symptoms (30% of cases). In the absence of brain metastases, 30% to 50% of patients will develop brain metastases within the first two years of treatment, depending on whether the disease is hormone receptor...
This phase II trial studies whether different imaging techniques can provide additional and more accurate information than the usual approach for assessing the activity of tumors in patients with newly diagnosed glioblastoma. The usual approach for this currently is magnetic resonance imaging (MRI). This study is trying to learn more about the meaning of changes in MRI scans after treatment, as while the appearance of some of these changes may reflect progressing tumor, some may be due the treatment. Dynamic susceptibility contrast (DSC)-MRIs, along with positron emission tomography (PET) and/or magnetic resonance (MR) spectroscopy, ...
observation of IDH1 and OCT4 markers level and high grade astrocytoma patients prognosis after excision.
The goal of this interventional study is the development and validation of imaging markers, MRI and PET, plasma biomarkers, and/or cell markers that could support clinicians and researchers in differentiating pseudoprogression from true tumor progression in routine clinical activities and clinical trials in patients affected by glioblastoma. The endpoints of the study are: - the elaboration of predictive models using imaging advanced biomarkers, PET and MRI, biological serum markers, and cancer cell derived makers to differentiate tumor pseudoprogression or real progression in patients affected by glioblastoma who...
This is an open-label, single-arm, phase I/II trial of immune checkpoint inhibitor combined with pemetrexed intrathecal injection for leptomeningeal metastasis from solid tumors, to evaluate the safety and efficacy.
This is a prospective, single-arm, open clinical study, which was designed to evaluate the efficacy and safety of an immune checkpoint inhibitor combined with pemetrexed intrathecal injection in the treatment of patients with NSCLC associated with leptomeningeal metastases.
The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise but have not been strong enough to cure most patients. In order...
In Australia, glioblastoma (GBM) has a higher annual fatality rate than a variety of other cancers, such as melanoma, bladder, and kidney tumors. While the 5-year survival rate for other cancers, such as breast and prostate cancer, has increased, there have been no notable advancements in GBM during the past ten years, and the incidence and mortality patterns have barely changed between 1982 and 2011. In particular, GBM poses a challenging therapeutic dilemma for patients and physicians due to its aggressive biology and resistance to available treatments. Recent studies showed that cytomegalovirus (CMV) is expressed in GBM tumors, ...
