Abstract

BACKGROUND: During 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 method 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 the age, sex, child-pugh score, liver cirrhosis, and the level of AFP.
RESULTS
Pulmonary metastasis was found in 18.0% (26/144), of witch 92.3%(24/26) and 7.7%(2/26) of the patients with and without transarterial chemoembolization, respectively. Of thepatients, 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 precipitating factors for pulmonary metastasis in TAE in our study. Our results suggest that regular chest X-ray check-up may be more frequently needed by patients who had TAE treatment for hepatocellular carcinoma.
