Incidence and clinical outcome of icteric type hepatocellular carcinoma.

BACKGROUND

To elucidate the incidence of the rare cases of icteric type hepatocellular carcinoma (IHCC), we conducted a retrospective study. The clinical outcomes of IHCC cases were also analyzed.

METHODS

From January 1986 to December 1997, newly diagnosed HCC cases were evaluated and reviewed from an admission registration database in a medical center. Patients who had HCC tumors which were located within biliary tracts, and caused obstructive jaundice as the initial clinical manifestation of HCC, were defined as cases of IHCC. Besides clinical manifestations, the outcomes and survival times of various treatment strategies among the IHCC cases were compared retrospectively.

RESULTS

The incidence of IHCC was 0.53% (10/1897). The median age of the 10 IHCC patients (seven men, three women) was 56.1 years (range = 41-72 years). Most primary HCC lesions (80%) were of expansive type: either single nodular type or multinodular type. All the patients eventually died of cholangitis and sepsis. Besides biliary drainage, seven patients of moderate to good liver reserve function received transarterial chemoembolization (TACE) for palliative treatment, and three of these received additional radiotherapy (R/T) because of the limited effect of TACE (total dosage ranged from 1600 to 5000 cGy). One patient received only radiotherapy (total dosage 1600 cGy) because of having a single tumor and poor liver reserve function. The median survival time among those eight patients who received palliative treatment was 13.4 months (range = 8-26 months), which was significantly longer than for the other two patients without treatment (2 and 4 months).

CONCLUSIONS

Icteric type hepatocellular carcinoma (IHCC) is a rare presentation of HCC. Palliative treatment strategies, including TACE and/or R/T showed a beneficial effect in improving the survival time.
