Filter by:This study was a retrospective observational study. The study included patients with non-small cell lung cancer with ALK-fusion brain metastases or meningeal metastases who received first-line and late-line treatment with the third-generation ALK TKI lorlatinib between June 2022 and June 2023. Data were collected from the electronic medical records database and hospital information system of many hospitals in Sichuan Province. Clinical pathology features including gender, age, ALK mutation status at diagnosis, and clinical stage at diagnosis were collected from the medical records. The physical condition assessed by ECOG-PS before the administration of lorlatinib was recorded. Information on anti-tumor therapy was obtained from the records, including dose and time of ALK-TKI therapy and tumor response, number of prior systemic therapy lines, drug regimen, efficacy, and whether local therapy such as radiotherapy and surgery had been received. In this study, the sample size is not limited, and information is collected according to the maximum number of patients. The study period was from 01 July 2023 to 30 June 2024.
This study is an ambispective cohort study to evaluate the displacement and deformation of large brain metastases (BM) treated with magnetic resonance imaging-guided adaptive radiotherapy (MRIgART)
While many studies have investigated the prognostic factors for patients undergoing surgical resection for primary brain tumors, decision-making for patients with brain metastasis (BM) is more complex because of their higher burden of comorbidities compared to those with primary brain tumors. In addition, although various prognostic indicators have been identified to predict prognosis in several types of cancer, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and systemic immune-inflammation index (SII), limited studies have yet determined which group of patients would yield beater survival outcome after surgical resection for BM. This study aimed to investigate the impact of patient and perioperative characteristics and prognostic indicators on survival outcome of patients undergoing surgical resection of BM.
REPOSE is a phase II clinical trial exploring the safety and efficacy of repotrectinib in patients with non-small cell lung cancer (NSCLC) characterized by the presence of brain metastasis (BM) and whose tumors have mutated ROS proto-oncogene 1, receptor tyrosine kinase (ROS1) gene.
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.
This study is an investigator-initiated, prospective, open-label, single-arm, multicenter clinical trial aimed at exploring the antitumor activity of Lorlatinib in ALK-positive NSCLC patients with brain/ leptomeningeal metastases.
This study aims to evaluate the safety and efficacy of hippocampal-sparing WBRT combined with SRS as first-line treatment for SCLC patients with brain metastases.
The goal of this interventional phase III clinical trial is to evaluate objective intracranial response rate (iORR) after a treatment with total cranial radiation therapy plus concomitant transdermal nitroglycerin (NTG) addition or total cranial radiation therapy only in patients with stage IV non-small cell lung cancer with brain metastases and EGFR mutation. The main questions it aims to answer are: Determine progression-free survival (PFS) to CNS and overall survival (OS). Evaluate and compare the quality of life (QoL) of patients during and after treatment. Evaluate the cognitive function of patients before, during and after treatment. Evaluate treatment-associated toxicity to grade adverse treatment events Evaluation of HIF1α, VEGF and ROS1 in peripheral blood before and after nitroglycerin treatment. All participants will have laboratory tests at the beginning and end of radiation therapy. Cranial MRI will be performed prior to treatment and 12 weeks after the end of treatment, then every 16 weeks until intracranial progression. Patients in the interventional group will be given 36 mg patches of transdermal nitroglycerin for 24 hours with a 12-hour rest interval during treatment with radiation therapy. The control group will only receive total cranial radiation therapy at the same doses and with the same schedule.
The purpose of this study is to find out whether 68Ga-PSMA-11 PET/CT is effective in assessing tumor uptake (tumor activity seen in cancerous tissue) in participants with high-grade glioma/HGG or brain metastases.
The purpose of this study is to test an empirically supported psychotherapeutic intervention, Managing Cancer and Living Meaningfully (CALM), compared to treatment as usual (TAU) in those with malignant brain cancer diagnoses.
