Difference in Early Postoperative Recurrence Rate of Hepatocellular Carcinoma
According to the Imaging Modalities Used for Preoperative Staging : Comparison Between CTAP and CTHA,
Lipiodol CT and Three Phase Helical CT
Abstract
- BACKGROUND/AIMS
Computed tomography during arterial portography and computed
tomography during hepatic arteriography (CTAP and CTHA), one of the most sensitive method
in detection of hepatocellular carcinoma (HCC) nodules , is reported to reduce
unnecessary operation of HCC. However, it is not clear whet her CT AP and CT HA can
reduce early post operative recurrence rate of HCC. We performed this study to find
any differences in early postoperative recurrence rate of HCC according to the imaging
modalities used for preoperativest aging.
METHODS
Ninety-seven patients with HCC who had underg one curative hepat icres ection
from Dec.1994 to Mar. 1998 were included (median age = 52 years (26-78), M:F = 85:12).
They were classified into 3 groups according to the imaging methods used for preoper
ative staging: CTAP & CTHA group (n=56), Lipiodol CT group (n=24), and three phase
helical CT group (n=16). No significant inter-group difference was found in preoperative
status of the patients or characteristics of HCC. One-year recurrence rates were
compared by log-rank test.
RESULTS
HCC recurred in 17 of 97 patients (18.7%) within 12 months.
A significant difference in 1- year recurrence rate was observed between the groups:
helical CT , may be a superior imaging modality for preoperative staging of HCC that
can reduce early postoperative recurrence rate.
