| Main Objective: The trial aims to investigate the safety and efficacy of verteporfin photodynamic therapy in patients with soft tissue sarcomas in the arms or legs. The primary endpoint is the diameter of necrosis of tumour achieved around a single fibre for a given light energy. We aim to establish the minimum light dose, in the range 20J to 50J, required to induce an area of necrosis with a diameter of at least 12mm. Once we have established the light dose that achieves this in 3 consecutive patients, we will study a further 7 patients with the same light dose.;Secondary Objective: What effect does photodynamic therapy have on the histopathology of the tumour and normal surrounding tissues? To look at the effect of Photodynamic Therapy on the tumour and normal soft tissues and study if necrosis extends to normal tissue. What effect does photodynamic therapy have on the MRI appearance of the sarcoma? To radiologically assess the response of the Photodynamic Therapy on sarcomas we will use pre and post PDT MRI and compare with final histology. We will measure the diameter of necrosis on MRI scan which will be compared with the histological measurement.;Primary end point(s): The primary outcome is the maximum diameter of the area of necrosis (mm) achieved around a single fibre for a given light energy. We aim to achieve a 12mm zone of necrosis in the tumour. | — |
