Focal therapy for prostate cancer: fact or fiction?
Prostate cancer is the commonest male cancer diagnosed in men in the UK, and the treatment of organ confined prostate cancer is a subject of much debate. Focal therapy for prostate cancer intends to treat the cancer within the prostate, whilst sparing the majority of the benign prostate tissue. In addition, the intention is to avoid treatment effects in the surrounding structures, the damage of which leads to the side effects commonly associated with radical whole gland therapies. This relies on accurate localization of the prostate cancer by biopsy and imaging followed by treatment using a modality capable of delivery to a focal area within the prostate. Focal therapy lies between the current extremes of radical whole gland treatment and active surveillance. There have been many articles reviewing the concept of focal therapy for organ confined prostate cancer, but with a paucity of data available for analysis. This is being addressed with an increase in the published data on focal therapy, using a number of different modalities. In this review, we address the question of whether the data currently published does in fact support the further development of the focal therapy approach, or whether it is a concept best relegated to the realms of fiction.
