This pilot study was designed to assess the potential of photodynamic therapy (PDT) using meso tetra hydroxy phenyl chlorin (mTHPC) for organ confined prostate cancer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design\/Patients and Methods<\/jats:title><jats:p>Six men with organ confined prostate cancer were photosensitised with mTHPC (0.15 mg\/kg). Between 2 and 5 days later, red light (652 nm) was delivered to areas of biopsy proven cancer via fibres inserted through transperineal needles (50\u2013100 J per site).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After 8 of 10 PDT sessions, the prostate specific antigen (PSA) fell by up to 67%. Early MRI scans showed oedema and patchy necrosis, which resolved over 2 months. Biopsies of treated areas revealed necrosis and fibrosis at 1\u20132 months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>PDT for primary prostate cancer appears safe and can reduce PSA levels. As this was a phase I study, no attempt was made to treat the whole prostate; this or targeted tumour ablation could be attempted in a phase II study with an increased number of fibres. This technique merits further investigation in early prostate cancer. Lasers Surg.
