Filter by:Patients with lung cancer and brain metastases undergo HA-WBRT-SIB using image-guided radiotherapy, receiving a total dose of 30-36 Gy delivered in 18-20 fractions to the whole brain (CTV), while the dose to the GTV is boosted to 44 Gy-52 Gy in 18-20 fractions, five times a week. The optimal mean dose (Dmean) to the bilateral hippocampus should optimally be ≤ 8 Gy, with a mandatory maximum dose (Dmax) to the hippocampus not exceeding 10 Gy; the preferred Dmean to the hippocampus PRV should optimally be ≤ 9 Gy, while the mandatory Dmax to the hippocampus PRV should be ≤ 12 Gy. The HVLT-R immediate recall scores are obtained at baseline and 1, 3, and 6 months after treatment.
The investigators collected the data from the investigators' center between January 2011 and October 2020. The study included all non-small cell lung cancer patients with surgically excised brain metastasis. The investigators analysis the correlation of gene mutation and the disease course.
Stereotactic radiotherapy (SRT) is being widely accepted as a treatment of choice for patients with a small number of brain metastases and an acceptable size, allowing a better target dose conformity resulting in high local control rates and better sparing of organs at risk. Currently, imaging for such a delivery technique requires both a recent magnetic resonance imaging (MRI) brain study for volume definition and a computed tomography (CT) scan for SRT planning. An MRI-only workflow could reduce the risk of misalignment between the two imaging modalities and shorten the delay of planning. Given the absence of a calibrated electronic density on MRI, the investigators aim to assess the equivalence of synthetic CTs generated by a generative adversarial network (GAN) for planning in the brain SRT setting.
This is a phase II, Open-Label, Multicenter, Prospective Clinical Study to Investigate the Efficacy and Safety of Tislelizumab Combined with Pemetrexed/ Carboplatin in Patients with Brain Metastases of Non-squamous Non-small Cell Lung Cancer. The primary end point is PFS, and secondary endpoint is ORR, OS, DoR and Neurocognitive impairment. during the study, the exploratory objectives including (1) PD-L1 expression, TMB, and other potential predictive biomarkers, correlated with response to treatment (2) Progression-free survival based on intracranial response (iPFS) according to RECIST 1.1 and RANO-BM
This is a multi-center, open-label, dose escalation study to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and maximum tolerated dose (MTD) of QBS10072S in patients with advanced or metastatic cancers with high LAT1 expression. The MTD of QBS10072S will be confirmed in patients with relapsed or refractory grade 4 astrocytoma.
This is a multicenter, international, open-label, single-arm, multicohort, two-stage optimal Simon's design, phase II clinical trial
An Open-label, Single-arm, Single-dose, Prospective, Multicenter Phase 2b Study to Establish Image Interpretation Criteria for 18F-Fluciclovine Positron Emission Tomography (PET) in Detecting Recurrent Brain Metastases After Radiation Therapy
An open-label, single dose, single arm, prospective, multicenter Phase 3 study to establish the diagnostic performance of 18F fluciclovine positron emission tomography (PET) in detecting recurrent brain metastases after radiation therapy
In this Phase I clinical study, the investigators plan to offer investigational treatment with the novel JAK2/STAT3 inhibitor WP1066 (Moleculin Biotech, Inc.) to pediatric patients with any progressive or recurrent malignant brain tumor that is refractory to standard treatment and is without known cure.
This clinical trial was designed to investigate the efficiency and toxicity of tomotherapy as primary radiotherapy for multiple brain metastases.
