ABSTRACT
Locoregional therapies (lrts) play an important role in the treatment of hepatocellular carcinoma (hcc), with the aim of increasing overall survival while preserving liver function. Various forms of lrt are available, and choosing the best one depends on technical aspects, liver morphology, tumour biology, and the patient's symptoms. The purpose of the present review article is to provide an overview of the current evidence relating to the use of percutaneous ablation, transarterial chemoembolization, and transarterial radioembolization for the curative or palliative treatment of hcc. Special situations are also reviewed, including the combined use of systemic therapy and lrt, indications and techniques for bridging to transplant and downstaging, and the use of lrt to treat patients with hcc and macrovascular invasion.

Approximately 5% of patients with end-stage cirrhosis undergoing orthotopic liver transplantation have occult hepatocellular carcinoma. Careful follow up is required to detect recurrent tumour, and knowledge of the patterns of recurrence may avoid diagnostic confusion with other malignancies, such as post-transplantation lymphoproliferative disorder. This case report illustrates an unusual presentation of recurrent hepatocellular carcinoma in a 56-year-old man presenting with a para-aortic soft tissue mass, thought clinically and radiologically to represent lymphoma or post-transplantation lymphoproliferative disorder. This case demonstrates that recurrent hepatocellular carcinoma can present late after transplantation as retroperitoneal lymphadenopathy, and should alert physicians and radiologists to be aware of the radiological appearances of recurrence and of the need for early biopsy to avoid diagnostic confusion with other malignancies.
