-Abstract-
Background/Aims : Hypoxia upregulates insulin-like growth factor II (IGF-II) and thus,
stimulates the growth of hepatocellular carcinoma (HCC) cells. We evaluated
prospectively the changes of plasma IGF-II levels in HCC patients following
transcatheter arterial chemoembolization (TACE), which usually gives hypoxic insults to
liver tissue. We also evaluated the association between the changes of plasma IGF-II
levels following TACE and the progression of HCC, especially in relation to metastasis.
Methods : Plasma IGF-II levels were measured before and 4 weeks after TACE in 46
patients with HCC. Three months following TACE, plasma IGF-II levels of the patients
were evaluated for the presence of metastases. Results : In 13 of the 46 subjects,
plasma IGF-II levels were decreased more than 20% (Group I); those of 18 patients
were changed within 20% (Group II) and those of 15 were increased more than 20%
(Group III). Plasma IGF-II levels tended to be increased in patients with large-sized
tumors, high serum AFP levels and heterogeneous uptake of Lipiodol. In 8 patients
(60%) of Group III, metastatic foci were observed, in contrast to 3 patients (17%) of
Group II and none of Group I (p=0.001). In multivariate analysis, high Child-Pugh score
and the increasing plasma IGF-II levels were independent risk factors for metastasis.
Conclusions : it is suggested that increased plasma IGF-II levels which is common in
patients with large-sized tumors and high serum AFP levels, might be closely
associated with the metastasis of HCC following TACE.
