Abstract
Background: During the follow up period after transarterial embolization(TAE), cases of pulmonary metastasis were more prevalent in TAE-treated patients than in TAE-untreated patients. Therefore, a study was conducted to evaluate whether TAE increases the incidence of pulmonary metastasis of hepatocellular carcinoma and to clarify the risk factors for pulmonary metastasis. Methods: From March 1991 to March 1995, 156 patients who had been diagnosed with hepatocellular carcinoma by serology, and radiographic and histologic methods at Yeungnam University hospital were involved in this study. We excluded 12 patients with lung metastasis on initial diagnosis and the others. The remaining 144 patients had been followed up for at least 5 months and, divided into four groups according to lung metastasis and trans-arterial embolization treatment, and evaluated for age, sex, child-pugh score, liver cirrhosis, and level of AFP. Results: Pulmonary metastasis was found in 18.0% (26/144), of which 92.3%(24/26) and 7.7%(2/26) of the patients with and without transarterial chemoembolization, respectively. Of the patients, 23.5% (24/102) with TAE had lung metastais during follow-up periods and 4.7% (2/42) without TAE had lung metastasis. There was more likelihood for lung metastasis after TAE. but there was no difference between two groups in age, sex, child-pugh class, the presence of liver cirrhosis, and AFP. Conclusions: The incidence of pulmonary metastasis of hepatocellular carcinoma after TAE was higher. Child-pugh class was the only related clinical preciptating factors for pulmonary metastasis in TAE in our study. Our results suggest that regular chest X-ray check-ups may be more frequently needed by patients who had TAE treatment for hepatocellular carcinoma.
1991년 3월부터 1995년 3월까지 영남대학교 의과대학 부속병원 내과에서 입원해서 혈청학적, 방사선학적 및 조직학적으로 간세포함으로 진단받은 156명의 환자 중 진단당시부터 폐전이를 동반한 12명(7.7%)을 제외한 144명의 환자를 대상으로 최소한 5개월 이상을 추적관찰하여 폐전이를 동반한 경우와 동반하지 않은 경우로 나누어 나이, 성별, Child-Pugh 점수, 간경변증 동반유무, AFP치 및 간동맥 색전술여부 등을 조사하여 그 차이점을 비교 분석하여 다음과 같은 결과를 얻었다. 추적관찰 중 폐전이를 동반한 경우가 26례(18.0%)였는데 간동맥 색전술을 시행한 경우가 26례 중 24례(92.3%), 시행하지않은 경우가 26례 중 2례(7.7%)였다. 폐전이를 동반하지 않은 118례 가운데 간동맥 색전술을 시행한 경우가 78례, 시행하지 않은 경우가 40례였다. 따라서 간동맥 색전술 시행후 폐전이를 동반한 경우가 102례 중 24례(23.5%), 간동맥 색전술을 시행하지 않고 폐전이를 동반한 경우가 42례 중 2례(4.7%)로 나타나서 간동맥 색전술 이후 폐전이가 더 빈번함을 알 수 있었다(p<0.01). 그러나, 나이, 성별, Child-Pugh 접수, 간경변증 동반유무 및 AFP치는 차이를 보이지 않았다. 결론적으로 간세포암에서 간동맥 색전술 이후 폐전이가 보다 많이 동반됨을 알 수 있었고 이에 관련되는 근본적인 설명과 그외 관련인자들에 대한 보다 많은 연구가 필요할 것으로 사료된다.
