Double-Dose Third-Generation EGFR-TKI Plus Bevacizumab and Intrathecal Chemotherapy for Refractory Leptomeningeal Metastatic NSCLC: A Phase II Study

The goal of this clinical trial is to explore the efficacy and safety of double-dose third-generation EGFR-TKI combined with bevacizumab and intrathecal chemotherapy in treating advanced non-small cell lung cancer (NSCLC) patients with leptomeningeal metastasis that progressed after prior standard-dose third-generation EGFR-TKI treatment. It also aims to investigate the correlation between cerebrospinal fluid genetic characteristics and prognosis as well as subsequent efficacy prediction in patients with leptomeningeal metastasis after resistance to standard-dose third-generation EGFR-TKI. The main questions it intends to answer are: Does this combined treatment regimen improve leptomeningeal metastasis response rate (LM-ORR) evaluated by RANO-LM? What adverse events occur in patients during the treatment with this combined regimen? Researchers will conduct a single-arm phase II prospective study to assess the effectiveness and safety of the combined treatment, without a control group comparison. Participants will: Receive double-dose third-generation EGFR-TKI (osimertinib 160mg qd, furmonertinib 160mg qd, or almonertinib 220mg qd) + intrathecal pemetrexed (induction phase: 10mg twice a week for 4 weeks; maintenance phase: 10mg once a week for 4 weeks; consolidation phase: 30mg every 4 weeks until disease progression or intolerable toxicity) + bevacizumab 7.5mg/kg. Undergo screening assessments within 28 days before enrollment, including tumor imaging, laboratory tests, and cerebrospinal fluid examination. During the treatment period, conduct regular checkups and tests (such as blood routine, blood biochemistry, electrocardiogram, and imaging examinations) according to the protocol (once every 4 weeks in the first two treatment cycles, then once every 8 weeks). Complete quality of life assessment using the QLQ-C30 scale every 4 weeks and record changes in neurological symptoms and ECOG scores.

Smartphone-based Remote Symptom Monitoring to Improve Postoperative Rehabilitation Exercise Adherence After Video-assisted Thoracic Surgery (VATS) for Lung Cancer

Brief Summary: This randomized controlled trial aims to evaluate whether active remote symptom monitoring and management via a smartphone app utilizing electronic patient-reported outcomes (ePRO) can improve adherence to prescribed outpatient pulmonary rehabilitation exercises among postsurgical lung cancer patients. Eligible patients will use the app for perioperative care and be randomized to an intervention group receiving ePRO-based symptom monitoring with clinician feedback or a control group receiving ePRO without feedback. The primary outcome is rehabilitation exercise adherence rate over 1 month after discharge. If proven effective, the app-enabled remote rehabilitation model can be scaled up to enhance recovery for more postoperative patients. Due to slower-than-expected recruitment, an interim analysis was introduced through a protocol amendment. The amendment was approved by the Ethics Committee before conducting the analysis, and the plan was incorporated into the updated study record. The interim review evaluated feasibility and informed the addition of mean weekly exercise duration as a co-primary endpoint with adjusted statistical thresholds.
