Study summary

The primary aim for this trial is to assess whether the RFA aspirator device is safe and of clinical benefit in patients with primary or secondary malignant liver tumours

Read the detailed description

Patients with unresectable primary or secondary malignancies of the liver have limited treatment options which often only give a small survival benefit. RFA has been demonstrated to be effective in local tumour eradication and to extend patient survival. In this study RFA aspiration will be used to treat unresectable primary or secondary tumours of the liver. RFA will be used to develop a shell of tissue destruction around the tumour, with aspiration removing tissue and fluid from the centre of the lesion. The potential advantages of aspirating during ablation could be to reduce aerosol spread of tumour within the liver parenchyma and peritoneum. Additionally, aspirating the ablated tissue may reduce the incidence of systemic side effects related to RFA when larger lesions are treated. This study would establish the safety and efficiacy of RFA aspiration in the treatment of unresectable primary/secondary malignancies of the liver.

This protocol is for a prospective multi-centre clinical trial of the use of RFA aspiration in the treatment of patients with primary/secondary malignancies of the liver, which are not suitable for formal liver resection. The basis for unresectability being the presence of extra-hepatic disease, limited liver synthetic function, co-morbidity (ASA>3), bilobar disease and anatomical location. Early and late complications relating to the usage of the RFA aspirator will be analysed. Additionally, local recurrence and long term survival will be assessed. If the use of the RFA aspirator produces improved survival with minimal morbidity and mortality. Then these initial results will justify further in depth studies to establish its clinical role.

II. SPECIFIC AIMS/OBJECTIVES

The primary aim for this trial is to assess whether the RFA aspirator device is safe and of clinical benefit in patients with primary or secondary malignant liver tumours.

III. STUDY OVERVIEW

It is anticipated that 100-200 participants will be recruited. The time period for patient recruitment will be for 2 years with follow up for 3 years. The total study period will be 5 years in order to allow the assessment of complications, local ablation success and survival benefit.
