Filter by: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 OS,iPFS, PFS, iORR, safety, neurocognitive function and quality of life between the two groups were compared.
Contrast-enhanced magnetic resonance imaging is the most widely used examination for detecting the presence of brain metastasis. Functional sequences such as perfusion weighted imaging makes it possible to differentiate tumor recurrence from cerebral radionecrosis. However, this imaging technique may exhibit limitations, especially for brain lesions consisting of a mixture of necrotic tissue and tumor progression or depending on the location of the lesion in the brain. The use of 18F-DOPA PET is another option available to oncologists. Many studies on gliomas showed the superiority of this imaging technique over contrast-enhanced MRI. However, this imaging solution has been very poorly studied for brain metastases. The new PET technology equiped with silicon detectors makes it possible to obtain greater sensitivities than those of previous generations. It also make possible to obtain images in very short acquisition times. After injection, the hardware allows to obtain the perfusion kinetics of the lesion thanks to a very short temporal sampling (i.e. three seconds). The main objective of this pilot study is to evaluate the association between early activity measurements (< 4 minutes post-injection) of 18F-FDOPA in PET and the differential diagnosis between radionecrosis and recurrence of cerebral metastases treated by radiotherapy.
Collection of ctDNA and TCR data to predict the efficacy and prognosis of brain radiotherapy in patients with brain metastases from non-small cell lung cancer (NSCLC) in a comprehensive manner
To learn if the combination of niraparib and dostarlimab can help to control advanced cancer that has spread to the brain.
The purpose of this research is to see if monitoring the brain using magnetic resonance imaging (MRI) after radiation therapy will allow investigators to find cancer that has spread to the brain (brain metastases) before it causes symptoms.
To learn if the study drugs, tucatinib and adotrastuzumab emtansine (T-DM1), can help to control solid tumors that have spread to the brain.
This is a prospective, single-center observational clinical study aimed at the efficacy and safety of radiotherapy combined with PD-1 inhibitors and chemotherapy in the treatment of Chinese patients with symptomatic NSCLC with brain metastases.
The goal of this observational study is to learn about the survival benefit of local therapy combination with target therapy in lung cancer brain metastases with EGFR mutation. The main questions it aims to answer are: - Is local therapy performed before or after target therapy would provide survival benefit ? - What kind of local therapy combining with target therapy would provide survival benefit, neurosurgical resection or radiotherapy?
The goal of this observational study is to learn about treatments in brain metastases with poor prognostic factors. The main questions it aims to answer are: - What kind of local treatment provides a survival benefit for patients with poor prognostic factors? - What kind of systemic treatment provides a survival benefit for patients with poor prognostic factors? - Will the combination of local treatment and systemic treatment provide a survival benefit for patients with poor prognostic factors? Participants will be asked to provide personal information about their living status, symptoms, and disease control during the follow-up.
The objective of this trial is to assess the safety and feasibility of delivering SBRT to patients with limited BMs (less than 10 lesions of lung cancer) by establishing the maximally tolerated dose (MTD) of SABR in 5 fractions.
