Incidence of Hepatocellular Carcinoma and Cumulative Long-term Survival Rate
in Patients with Membranous Obstruction of Inferior Vena Cava
Abstract
- Membranous obstruction of inferior vena cava (MOIVC) has been known as
one of the risk factors for hepatocellular carcinoma (HCC). However, the incidence
of HCC in patient with MOIVC or the effect of treament on the natural history of the
patients has not yet been evaluated. The present study was to analyze the incidence
of HCC and the survival rate, and then, to determine whether treatment may modify
the clinical course.
METHODS
The medical records of 39 patients diagnosed as MOIVC
at Seoul National University Hospital from December 1984 to November 1997 were
retrospectively analyzed.
RESULTS
Seven patients had HCC at the time of diagnosis.
We performed angioplasty for 21 of the rest patients, surgery for 4, and supportive
care for 7. The 5- and 10-year survival rates of all patients were 90% and 69%, respectively.
The 1-, 2- and 7-year incidence of HCC was 5%, 11% and 26%, respectively. The 10-year
survival rates of treated and non-treated patients were 75% and 66%, respectively (p>0.05).
The 5-year incidence of HCC in treated and non-treated patients was 14% and 0%,
respectively (p>0.05).
CONCLUSIONS
The treatment of MOIVC did neither increase
survival rate nor prevent the development of HCC. Therefore, the efficacy of treatment
for MOIVC should be reevaluated and patients should be followed up for the detection of HCC.
