Laparoscopic Surgery VS RFA for Recurrent HCC

Management of recurrent HCC is urgent and several treatments have been developed .Repeat hepatectomy is considered to be the first choice for recurrent HCC. Unfortunately, repeated open hepatectomy can be performed only in a small proportion of patients due to inadequate liver function reserve, widespread recurrence or high invasiveness. Given that recurrent tumors are usually detected at small size during follow-up after initial surgery, radiofreqency ablation (RFA), which is less invasive, may be locally curative and causes minimal damage to liver function reserve,has been widely used. However, the re-recurrence rate after RFA is more than 50%,and the recurrence-free survival is less than 20%. Recently, satisfactory short- and long-term oncological outcomes have been reported for laparoscopic surgery (LS) for the treatment for primary HCC with cirrhosis. Some single center pilot studies reported that LS may, compared with open surgery, improve the prognosis of HCC with less blood loss and shorter hospital stay. LS was initially considered not suitable for recurrent HCC due to postoperative adhesions that might make laparoscopic surgical procedure more difficult and less safe. With improvement in technique and experience, recent studies showed that LS for recurrent HCC in cirrhotic patients is a safe and feasible procedure with good short-term outcomes. However, thus far, no study has been performed to evaluate the long-term oncological outcomes of LS for recurrent HCC, and compare those results to that for RFA. To clarify these issues, a multicenter retrospective comparative study by using propensity score matching method that included a large consecutive series of patients with recurrent HCC within Milan criteria, who underwent LS or RFA, was performed.
