This cohort study aims to investigate the clinical value of Hybrid APC for treatment of early central lung cancer.

Primary Outcome Measures

  • Successful remission rate: [ Time Frame: 3 months ]
    successful remission is defined as absence of intraepithelial neoplasia in biopsies of original locations at 3 months after HybridAPC upon follow up

Secondary Outcome Measures

  • Complications [ Time Frame: 3 months ]
    possible complications include perforation, bleeding, fever, stenosis, cough and etc.
