| E.4 | Principal exclusion criteria | 
1.All patients whose current pre-operative cardiac evaluation does not show their fitness for a procedure requiring general anesthesia; 2.Patients with a history of inflammatory bowel disease or other factors which may increase the risk of fistula formation; 3.Men who have received any hormonal manipulation (excluding 5-alpha reductase inhibitors) or androgen supplements within the previous 6 months; 4.Men previously treated by radiation therapy (external therapy or brachytherapy) or chemotherapy or any therapy for prostate cancer; 5.Men who have received or are receiving chemotherapy for prostate carcinoma or other significant cancer; 6.Men who have undergone previous TURP (trans-urethral resection of the prostate); 7.Men who are currently (within the month before the treatment procedure) receiving any medications having potential photosensitizing effects (e.g. tetracyclines, sulfonamides, phenothiazines, sulfonylurea hypoglycemic agents, thiazide diuretics and griseofulvin);  8.Men who are currently receiving anticoagulant drugs (e.g.: coumadin, warfarin)  9.Patient who stopped long term treatment of acetylsalicylic acid (aspirin) or other anti platelets agents less than 15 days before the procedure; 10.Patient suspected of Disseminated Intravascular Coagulation (DIC) as defined by the presence of three out of the five following criteria: platelets decrease, increase of PT, increase of aPTT, fibrinogen decrease, D-Dimer increase. 11.A history of sun hypersensitivity or photosensitive dermatitis; 12.Renal disorders (blood creatinine > 1.5 x ULN) or known post mictional residue > 150cc 13.Hepatic disorders (transaminases > ULN, bilirubin > ULN, GGT > ULN).  In case of slight abnormalities, another exam could be performed.  If the results are within normal ranges, then the patient can be included; 14.Hematological disorders (white cells < 2500/mm3, neutrophils < 1500/mm3, platelets < 140.000/mm3, Hb < 8 g/dl);

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
The result of the Month 3 12-core prostate biopsy will give the primary efficacy criterion of this study.  
 Primary criterion: success of the treatment for a patient is defined by negative biopsy in the treated lobes that initially contained the tumor(s).
