Gastrointestinal bleeding in cirrhotic patients with hepatocellular carcinoma undergoing intrahepatic artery chemotherapy.

Background: Hepatocellular carcinoma in cirrhotic patients increases the risk of variceal bleeding. We sought to characterize bleeding in a cirrhotic patient population undergoing intrahepatic artery chemotherapy for hepatocellular carcinoma and to determine the possible influence of this treatment on gastrointestinal bleeding.

Methods: We retrospectively reviewed 179 patients with hepatocellular carcinoma who underwent intrahepatic artery doxorubicin and cis-platinum chemotherapy to determine the incidence of gastrointestinal bleeding and compared them with 434 hepatocellular carcinoma historic controls not undergoing regional chemotherapy.

Results: Of the 179 patients, 27 patients (15.1%) developed upper gastrointestinal bleeding over a mean follow-up of 15.2 months; 18 of the 27 (66.7%) bled from a variceal source and 9 (33.3%) bled from a nonvariceal source: ulcer (n = 6), gastropathy (n = 1), Mallory-Weiss (n = 1), erosive gastritis (n = 1). Twenty-one patients developed bleeding after initiation of chemotherapy (14 variceal and 7 nonvariceal). The number of chemotherapy sessions among patients with variceal and nonvariceal bleeding was similar (2.1 +/- 0.4 and 4.0 +/- 1.2; p = Not significant). Patients with variceal and nonvariceal bleeding were comparable with respect to Child-Pugh classification, pTNM stage, age, time to bleeding, and gender.

Conclusions: Regional intra-arterial chemotherapy for hepatocellular carcinoma is associated with a low risk of variceal bleeding. Nonvariceal sources of upper gastrointestinal bleeding in this population account for a significant component of bleeding episodes.
