Abstract

Although exophytic endobronchial lesions can readily be diagnosed by routine forceps biopsy through the fiberoptic bronchoscope, submucosal or peribronchial tumor can be difficult to diagnose. So we evaluated the diagnostic utility of transbronchial needle aspiration (TBNA) through the fiberoptic bronchoscope in patients presenting with endoscopic abnormalities suggestive of submucosal or peribronchial tumor. Patients and Methods : Retrospective review of 120 lung cancer patients who were found to have the lesions suggestive of peribronchial and submucosal tumor during fiberoptic bronchoscopy was performed from Jan. 1994 to Dec. 2002 at Severance Hospital, Yonsei University College of Medicine. Results : Forcep biopsy was positive in 63 cases (52.5%) and TBNA in 91 (75.8%), which was significantly better than forcep biopsy (p=0.001). The combination of forceps biopsy and TBNA was positive in 106 cases (88.3%), which was significantly better than forceps biopsy alone (p=0.0001). The difference of TBNA yield according to cell type or bronchoscopic appearance of lesion was not significant, but it showed the relatively better result in small cell carcinoma. Conclusions : We concluded that TBNA significantly increase the yield over forcep biopsy alone in the detection of submucosal or peribronchial bronchogenic carcinoma.

목 적 : 폐암의 진단에 있어서 진단율이 낮은 기관지주위나 점막하 병변에서 TBNA의 진단율을 조직 생검과 비교하여 TBNA의 임상적인 유용성에 대해 조사하였다. 방 법 : 연세대학교 의과대학 세브란스병원에서 1994년 1월부터 2002년 12월까지 5,582예의 굴곡성 기관지내시경검사를 시행하였으며, 기관지주위나 점막하 병변을 보여 TBNA와 조직생검을 시행한 환자 중 폐암이 확진되었던 120예를 대상으로 후향적으로 조사하였다. 결 과 : 기관지주위나 점막하 병변을 가진 폐암에서 TBNA의 진단율은 75.8%로 생검(52.5%)에 비해 진단율이 높았으며(p=0.001), 생검 단독에 비해 TBNA와 생검을 병용하는 경우 진단율이 유의하게 높았다(88.3%, p=0.0001). 폐암의 세포형이나 내시경적 형태에 따른 TBNA의 진단율은 유의한 차이가 없었으나, 소세포암에서 좀 더 높았다. 결 론 : 기관지주위나 점막하 병변을 가진 폐암의 진단에 있어서 TBNA는 생검보다 진단율이 높았고 생검과 같이 시행함으로써 폐암의 진단율을 향상시킬 수 있었다.
