Background:
The lung cancer biopsy specimens obtained by endobronchial ultrasound-guide sheath (EBUS-GS) trans lung biopsy occasionally do not contain cancer cells. It is a problem that there is a possibility that they may not contain cancer cells.
Aim Of The Study:
To investigate the proportion of biopsy specimens containing cancer cells in total biopsy specimens.
Materials & Methods:
Patients with lung cancer diagnosed by EBUS-GS were selected. The primary end point was the proportion of specimens containing tumors in the total specimens obtained by EBUS-GS.
Results:
Twenty-six patients were investigated. The percentage of specimens containing cancer cells in the total specimens was 79.0%.
Conclusion:
The proportion of biopsy specimens containing cancer cell to all biopsy specimens by EBUS-GS was high, but not 100%.
