Abstract

An elevated serum CA19-9 level is an indication of pancreatic and biliary tract cancer. However, it has recently become known that nonmalignant gastrointestinal diseases and a variety of nonmalignant respiratory diseases, such as idiopathic interstial pneumonia, collagen vascular disease associated lung diseases, diffuse panbronchiolitis and bronchiectasis, can also show an elevated serum CA19-9 level. We recently encountered a case of bronchiectasis with persistently elevated serum CA19-9, but without any evidence of malignant disease in endoscopic retrograde pancreatocholangiography, abdominal computed tomography, and positron emission tomography. After serial follow-up of 3 years and 10 months, there was still no evidence of cancer. It is believed that the elevated serum CA19-9 level was due to bronchiectasis. An elevated serum CA19-9 level should be interpreted carefully with the patients' clinical condition.

CA19-9의 상승은 췌장 및 담도계 악성 종양을 시사하는 소견이다. 하지만, 최근에 양성 소화기계 질환 뿐 아니라 특발성 간질성 폐렴, 교원성 폐 질환, 미만성 범세기관지염, 기관지확장증 등 다양한 양성 폐 질환에서도 혈중 CA19-9 수치가 증가되어 있다고 보고된다. 저자들은 최근 지속적으로 혈중 CA19-9 수치는 증가되어 있지만, 내시경적 역류성 담도 췌장 조영술, 복부 전산화 단층 촬영, PET-CT에서 악성 종양이 발견되지 않은 기관지확장증 1예를 경험 하였다. 3년 10개월의 추적 관찰 기간 중에도 췌장암과 같은 악성 종양은 발견되지 않아서, 혈중 CA19-9 수치의 상승은 기관지확장증에 의한 것으로 추정 되었다. 혈중 CA19-9 수치의 상승은 환자의 임상 양상과 연관하여 조심스럽게 판단하여야 될 것으로 생각된다.
