In this retrospective study, the investigators assessed the application of radiofrequency-assisted liver resection in intractable liver cancer resection, and plan to analysis the different factors.

The primary clinical treatment of liver cancer is surgical resection, although many integrated applications develop rapidly, surgery is still the best way to remove the tumour lesion. Traditional ways that have curative removed tumours in three methods, which are liver resection, liver transplantation and radiofrequency ablation (RFA).

As for primary liver cancer, surgery, and RFA are both effective and safety, but for the complexity of end-stage liver cancer, surgical resection may not remove the tumours alone. Surgical resection with radiofrequency ablation therapy for intractable liver cancer is a kind of active plan. The therapy can eliminate the tumour, maximize the protection of patient liver tissue, reduce operation damage, reduce the incidence of complications, and improve patients quality of life after surgery.
