R. Murakami et al., THE VALUE OF EMBOLIZATION THERAPY IN PAINFUL OSSEOUS METASTASES FROM HEPATOCELLULAR CARCINOMAS - COMPARATIVE-STUDY WITH RADIATION-THERAPY, British journal of radiology, 69(827), 1996, pp. 1042-1044
We evaluated the therapeutic effect of transcatheter arterial emboliza
tion therapy (TAE) for painful osseous metastases from hepatocellular
carcinoma (HCC) in comparison with radiation therapy (RT). TAE using g
elatin sponge particles was performed for seven lesions in seven patie
nts. Selective catheterization and embolization were successfully perf
ormed in all lesions. Within 10 days after TAE, complete pain relief (
CR), partial relief(PR) and no relief(NR) were attained in 57%, 29% an
d 14%, respectively. RT was used to treat 34 lesions in 22 patients. T
he dose fractionation schedules were in the range 28.0-50.4 Gy, with 1
.8-4.0 Gy per fraction. CR: PR and NR were attained in 47%, 47% and 6%
, respectively. There were no serious complications related to these t
reatments. Both TAE and RT are effective and the treatment of choice s
hould be selected on an individual basis.
