Abstract

Introduction
Pleural malignancy, particularly malignant pleural mesothelioma (MPM) is increasing in incidence due to the long latency period from exposure to asbestos to development of the disease. MPM can be challenging to diagnose. For patients presenting without a pleural effusion, CT guided biopsy, remains the primary choice of biopsy, but the diagnostic sensitivity of this investigation is 70-75%. Therefore, a proportion of patients will go on to require further biopsies. If the first biopsy is non-diagnostic the chances of further non-diagnostic biopsies are high in MPM.

Methods:
TARGET is a multi-centre randomised controlled trial, aiming to recruit 78 patients over an 18-month period, from 10 centres in the UK. Patients will be randomised to either the standard arm which is a second CT guided biopsy, or the interventional arm, a PET-CT scan followed by a targeted CT guided biopsy. Patients will be followed up for 12 months (patients recruited in the last 6 months of recruitment will have 6 months of follow-up). MPM biomarker Mesothelin will be checked at baseline, at 6-month and 12-month follow-up appointments where patients.

Ethics and dissemination:
Ethical approval for this trial was granted by the South West – Exeter research and ethics committee (reference number 15/SW/0156). Results of the trial will be published in a peer reviewed journal and presented at an international conference.
