Core Tip
Core tip: Recently, many studies have reported the increasing treatment success rate and reduced frequency of complications following RFA treatment of tumors in difficult locations. However, the long-term outcomes of patients with tumors in difficult locations have been rarely reported. Our studies showed no difference in 5- or 7-year overall survival between the difficult location group and the control group even though the local progression rate was higher in the difficult group. These results highlight that optimized individual strategies could achieve acceptable efficacy and safety and could help to expand RFA indications and improve overall outcome.
