Background/aims: This study examined the prognostic power of hepatocellular carcinoma in patients presenting an episode of spontaneous bacterial peritonitis treated with 3rd generation cephalosporins or quinolones, and subsequent prophylaxis with norfloxacin until death or transplantation.
Methods: The study comprises the prospective evaluation of 168 consecutive cirrhosis patients presenting an episode of spontaneous bacterial peritonitis.
Results: Hepatocellular carcinoma was diagnosed in 35 out of the 168 (20%) patients included in the study (10 single; 25 advanced tumors). Renal impairment developed in 82 patients. Resolution of infection was achieved in 90% of the cases, the hospital survival being 70%. Renal impairment, advanced tumor stage, albumin, and GGT showed independent prognostic value for hospital mortality. At the end of follow-up 101 patients had died, the 1- and 2-year survival being 36% and 31%, respectively. Four variables independently predicted survival: advanced tumor (OR: 3.9; p=0.00001), renal impairment (OR: 2.1; p=0.00001), bilirubin (OR: 1.6; p=0.02) and creatinine (OR: 1.3; p=0.03). Advanced tumor retained independent predictability in patients surviving hospitalization (OR: 7.5; p=0.0001), the 6-month survival being significantly lower in patients with advanced tumor (12% vs 57%, p<0.00001).
Conclusion: The prevalence of hepatocellular carcinoma in cirrhotic patients with spontaneous bacterial peritonitis is high, and its presence should be actively sought. Advanced tumor impairs both hospital and long-term survival, and should be considered in the design of future trials.
