Osimertinib Combined With Intracranial SRT for EGFR-Mutant NSCLC With Symptomatic Brain Metastases

The goal of this retrospective real-world study is to evaluate the effectiveness and safety of first-line osimertinib combined with early intracranial stereotactic radiotherapy (SRT) in patients with EGFR-mutant non-small cell lung cancer (NSCLC) with symptomatic brain metastases. Eligible patients include adults with stage IV EGFR-mutant NSCLC who received first-line osimertinib monotherapy and early intracranial SRT. Data will be extracted from hospital medical records across multiple centers. The primary endpoint is real-world progression-free survival (rwPFS). Secondary endpoints include overall survival (OS), rwPFS2, time to next treatment or death (TTNT), and time to treatment discontinuation or death (TTD). Exploratory endpoints include CNS progression patterns, CNS progression-free survival (CNS PFS), CNS objective response rate (CNS ORR), and incidence of symptomatic CNS radiation necrosis.

Stereotactic Brain-directed Radiation With or Without Aguix Gadolinium-Based Nanoparticles in Brain Metastases

The purpose of this study is to determine whether AGuIX (Activation and Guidance of Irradiation by X-ray) gadolinium-based nanoparticles make radiation work more effectively in the treatment of patients with brain metastases that are more difficult to control with stereotactic radiation alone.

Stereotactic Radiosurgery as Second-line Therapy for Ventricular Tachycardia

The aim of the study is to compare the efficacy and safety of treating recurrent sustained Ventricular Tachycardia (sVT) after prior Catheter Ablation (CA) in patients with Implanted Cardioverter-Defibrillator (ICD) between re-do of conventional endocardial CA and Stereotactic Arrhythmia Radioablation (STAR).

Cadonilimab Combined With Stereotactic Radiotherapy as Second-line Treatment for Brain Metastases

The goal of this clinical trial is to evaluate the efficacy and safety of Cadonilimab combined with stereotactic radiation therapy in the second-line treatment of brain metastases from non-small cell lung cancer (NSCLC). The main questions it aims to answer are: * Does Cadonilimab combined with SRT in the second-line treatment of brain metastases provide better results? * Is the toxicity of Cadonilimab combined with SRT manageable in second-line treatment of brain metastases? Researchers will compare evaluate the efficacy and safety of Cadonilimab combined with SRT as a second-line treatment for patients with advanced NSCLC： * Receive Cadonilimab combined with SRT for brain lesions. * Visit the hospital regularly once every 12 weeks for checkups and tests

Longitudinal Study of Local Ablative Therapy in Oligometastatic Disease

This prospective national multicenter observational and interventional study aims to assess the longitudinal disease trajectory of patients with oligometastatic disease (OMD) who receive local metastasis-directed therapy. Patients with any category of OMD from any non-hematological cancer are eligible for inclusion. Local ablative therapy (LAT) includes surgical metastasectomy, radiotherapy, thermal ablation, and electroporations. The primary objective is to assess the time to failure of LAT strategy in patients with OMD from any primary cancer treated with all LAT modalities.
