Professor Stricker, who is now one of the most experienced in the world in focal NanoKnife therapy, was invited this month to do an editorial for a publication on focal NanoKnife therapy published from the Sloan Kettering in New York. Professor Stricker who has now done approximately 120 cases and has submitted results for focal NanoKnife therapy both in the setting of primary treatment and also after failed radiotherapy. He commented on the excellent outcomes in terms of sexual function and urinary function but did critique the study from Sloan Kettering. In particular he made a comment that patient selection in this group of people is critical to getting ideal outcomes and in his own series has recognised that the selection of the appropriate patient for focal NanoKnife therapy is critical to getting good outcomes both in terms of salvage treatment and primary treatment. In his own series, he is currently achieving an 80-90% clearance of tumour in the area treated in the primary and salvage setting.
