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%.
背景
通过支气管内超声引导鞘管（EBUS-GS）经肺活检获取的肺癌活检标本偶尔不含癌细胞。存在可能不含癌细胞这一问题。
研究目的
调查活检标本中含癌细胞的活检标本在总活检标本中的比例。
材料与方法
选取经EBUS-GS诊断为肺癌的患者。主要终点是EBUS-GS获取的总标本中含肿瘤的标本比例。
结果
对26例患者进行了调查。总标本中含癌细胞的标本百分比为79.0%。
结论
EBUS-GS获取的活检标本中含癌细胞的活检标本比例较高，但并非100%。
