Summary

The purpose of this study is to evaluate the relevance of intratumoral washing for detection of EGFR mutation (including T790M positivity).

Conditions

  • Non Small Cell Lung Cancer
  • EGFR Gene Mutation

Interventions

DIAGNOSTIC_TEST

Ultarthin bronchoscopy with intratumoral washing

Each subject with NSCLC will undergo bronchooscopic procedure. First, ultrathin bronchoscope is inserted and placed within tumor under radial EBUS, virtual bronchoscopic navigation, and fluoroscopy guidance. Then, intratumoral washing is performed. Subsequently, transbronchial lung biopsy is performed under radial EBUS, virtual bronchoscopic navigation, and fluoroscopy guidance.
