Abstract

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%.

与经支气管活检的所有活检标本相比，活检标本中含有肿瘤的比例。

背景:支气管超声引导鞘(EBUS-GS)经肺活检获得的肺癌活检标本偶尔不含癌细胞。问题是，它们可能不含癌细胞。研究目的:探讨含癌细胞的活检标本占总活检标本的比例。材料与方法:选取经EBUS-GS诊断为肺癌的患者。主要终点为EBUS-GS获得的含肿瘤标本占总标本的比例。结果:共调查26例患者。含癌细胞标本占标本总数的79.0%。结论:EBUS-GS法活检标本中含有癌细胞的比例较高，但不是100%。
