Second and third hepatectomies for recurrent hepatocellular carcinoma are justified

Abstract

Abstract Background Liver resection is the main curative treatment for hepatocellular carcinoma (HCC), but recurrence rates are high. The remnant liver is the most common site of recurrence, but the role of repeat hepatectomy in the treatment of recurrent HCC is controversial. Methods Patients who underwent curative hepatectomy for HCC and subsequent repeat hepatectomy for recurrent HCC between 1990 and 2007 were reviewed retrospectively. Clinicopathological characteristics, and early- and long-term outcomes of patients who had a first, second, third and fourth hepatectomy were compared. Results Some 1177 patients underwent a first hepatectomy for HCC, and 149, 35 and eight patients respectively had a second, third and fourth hepatectomies for recurrence. There were no significant differences in early postoperative outcomes after first and repeat hepatectomies. Five-year disease-free and overall survival rates after first, second and third hepatectomies were 43·6, 31·8 and 33·8 per cent (P = 0·772), and 52·4, 56·4 and 59·4 per cent (P = 0·879), respectively. Patients undergoing second and third hepatectomies for recurrence had better survival rates than those who did not have a repeat hepatectomy, but not those after fourth hepatectomy. Conclusion Second and third hepatectomies seem justified for hepatic recurrence of HCC. The role of fourth hepatectomy needs further investigation.
