Primary Tumor Resection With EGFR TKI for Stage IV NSCLC
- Conditions
- NSCLC Stage IV
- Interventions
- Procedure: therapeutic thoracic surgery
- Registration Number
- NCT05215548
- Lead Sponsor
- National Taiwan University Hospital
- Brief Summary
Our project is going to enroll patients with stage IV NSCLC with EGFR mutation and evaluate whether primary tumor resection after receiving the afatinib can prolong survival. This project is supposed to establish a new treatment protocol for stage IV NSCLC with EGFR mutation.
- Detailed Description
In Taiwan, non-small cell lung cancer (NSCLC) has been the leading cause of cancer death, making a phenomenal impact on public health. By understanding the oncogenic driver mutations of NSCLC (e.g. EGFR mutation or ALK rearrangement), the target therapy has taken the place of chemotherapy for its effectiveness and specificity, becoming the new standard of care for stage IV NSCLC. Despite the progress of medical treatment, the majority of patients with stage IV NSCLC still underwent disease progression after a period of time. Noticeably, more than half of the progression was restricted to the original sites of the tumor. It brings up the hypothesis that a combination of local consolidative therapy (e.g. surgery or radial therapy) and medical treatment could be beneficial for these patients. This has been advocated by the latest clinical trials as well.
Our project is going to enroll patients with stage IV NSCLC with EGFR mutation and evaluate whether primary tumor resection after receiving the afatinib can prolong the progression-free survival. This project is supposed to establish a new treatment protocol for stage IV NSCLC with EGFR mutation.

- Arm && Interventions
Group Intervention Description Group I : Surgery group therapeutic thoracic surgery The surgery group would receive take 12 weeks of EGFR TKI before randomization. After randomization, the surgery group would receive thoracic surgery with maximal regional control intent. Patients continue afatinib 1 to 2 weeks after surgery until disease progression or unacceptable toxicity. The residual local and metastatic sites of disease could undergo either surveillance or maintenance radio-treatment at the discretion of the treating physician. Group I : Surgery group Afatinib The surgery group would receive take 12 weeks of EGFR TKI before randomization. After randomization, the surgery group would receive thoracic surgery with maximal regional control intent. Patients continue afatinib 1 to 2 weeks after surgery until disease progression or unacceptable toxicity. The residual local and metastatic sites of disease could undergo either surveillance or maintenance radio-treatment at the discretion of the treating physician. Group II : Maintenance group Afatinib The control group would receive take 12 weeks of EGFR TKI before randomization. After randomization, the control group would receive afatinib until disease progression or unacceptable toxicity. The residual local and metastatic sites of disease could undergo either surveillance or maintenance radio-treatment at the discretion of the treating physician.
- Primary Outcome Measures
Name Time Method 2 year progression free survival rate start date of afatinib assessed up to 2 years Will be estimated using Kaplan-Meier method. The stratified log-rank test will be performed to test the difference in time-to-event distributions between treatment groups. Stratified Cox proportional hazards model will be utilized to include multiple covariates in the time-to-event analysis and to estimate hazard ratios.
- Secondary Outcome Measures
Name Time Method Progression free survival From the start date of afatinib assessed up to 4 years Will be estimated using Kaplan-Meier method. The stratified log-rank test will be performed to test the difference in time-to-event distributions between treatment groups. Stratified Cox proportional hazards model will be utilized to include multiple covariates in the time-to-event analysis and to estimate hazard ratios.
Overall survival From the start date of afatinib assessed up to 4 years Will be estimated using Kaplan-Meier method. The stratified log-rank test will be performed to test the difference in time-to-event distributions between treatment groups. Stratified Cox proportional hazards model will be utilized to include multiple covariates in the time-to-event analysis and to estimate hazard ratios.
Treatment-related adverse events From the start date of afatinib assessed up to 4 years It refers to the number of adverse events related to afatinib monotherapy or platinum-based chemotherapy as evaluated according to CTCAE v4.0.
R0 resection rate From the start date of afatinib assessed up to 12 weeks It is defined as the proportion of patients with negative surgical margin and no residual found under microscope after resection in all patients who have completed the thoracic surgery treatment.
resistant mutation events 12 weeks to 4 years Patient in the surgery and control group would receive next generation sequencing for tumor mutation check. The surgery group would receive next generation sequencing twice (1. after surgery 2. progression of disease or unacceptable toxicity.) The control group would receive next generation sequencing once (progression of disease or unacceptable toxicity.)
