Antibiotic prophylaxis in transarterial chemoembolization of hepatocellular carcinoma

Abstract Background and study aims Transarterial chemoembolization remains a common treatment option in unresectable hepatocellular carcinoma. However, protocols for pre- and post-procedure care and the role of antibiotic prophylaxis have not been evaluated. The aim of this work was to compare 3 different groups of prophylactic antibiotics in patients undergoing chemoembolization and to compare the efficacy of intravenous versus oral route. Patients and methods 180 hepatocellular carcinoma patients undergoing transarterial chemoembolization were selected. Patients were classified into 3 groups; Group 1: 60 patients; 30 received intravenous ceftriaxone, and 30 received oral cefixime. Group 2: 60 patients; 30 patients received intravenous levofloxacin and 30 received oral levofloxacin. Group 3: 60 patients; 30 received intravenous ciprofloxacin and 30 received oral ciprofloxacin. All antibiotics were given one day before intervention and for 4 days afterwards. Complete blood count, C-reactive protein, liver and renal function tests were assessed 1 and 5 days and then 1 month after the procedure. Results The ciprofloxacin group gave better results than the other 2 groups regarding total and differential leucocytic count and C-reactive protein level. No significant difference was found between oral and intravenous routes among the 3 groups. None of the studied patients developed infections or liver abscess after chemoembolization. Conclusion Third generation cephalosporin, levofloxacin or ciprofloxacin all are effective as prophylaxis against post-chemoembolization infections. No significant difference between oral and intravenous administration among the 3 groups. Oral ciprofloxacin is an effective, safe and relatively inexpensive prophylaxis regimen.
