Introduction: Transurethral resection of the prostate is considered the standard technique for patients with moderate or severe lower urinary tract symptoms related to benign prostatic hyperplasia (BPH). Pathologically BPH is characterized by an increased proliferation of stromal and acinar cells, sustained by increased vascularization (neoangiogenesis). Recent studies have also shown that finasteride reduces angiogenesis and prostatic bleeding associated with BPH. Reducing the volume as a final step in reducing neoangiogenesis could thus represent a fundamental advance in limiting intra- and postoperative bleeding in patients undergoing transurethral resection of the prostate (TURP). Materials and Methods: Our study included 60 patients undergoing TURP between January 2001 and January 2002. Of the patients, 30 received pretreatment with finasteride while 30 did not undergo any pretreatment (control group). In all the patients we evaluated the degree of peri-surgical bleeding, intended as a reduction in hemoglobin values in the 24 h following surgery. Results and Conclusions: In the group of patients pretreated with finasteride, blood loss, evaluated as a reduction in hemoglobin values, was minimal, and none of the patients required blood transfusion. The average hemoglobin loss in the 24 h following surgery was 0.9%. In the control group (average age 67 years), 4 patients (12%) required blood transfusion. The loss of hemoglobin was 2.36%. Finasteride, therefore, seems to play a fundamental role in the pretreatment of TURP patients, since by reducing dihydrotestosterone synthesis, it interacts with endothelial growth factors, thus reducing angiogenesis and preventing bleeding.

Background: Stereotactic body radiotherapy (SBRT) can emulate high dose rate brachytherapy (HDR-BRT) dose fractionation. We report our preliminary results using SBRT in monotherapy or pre-external-beam radiotherapy (EBRT) boost in patients with localized prostate cancer (LpC). The primary end point was the evaluation of both acute and late toxicities; secondary end point was the observation of prostate-specific antigen (PSA) nadir. Patients and Methods: Patients with LpC having prostate volume 90 cm 3 were enrolled in the present study. Patients were treated with SBRT alone or in combined modality (SBRT þ EBRT). SBRT was performed using a CyberKnife System (Accuray Incorporated, Sunnyvale, California) and fiducial tracking system. Results: From February 2008 to July 2013, 21 patients for monotherapy (38 Gy/4 fractions) and 5 for combined modality (9.5 Gy/2 fractions plus 46 Gy/23 fractions EBRT) were enrolled. Androgen deprivation therapy (ADT) was administered in 16 of the 26 patients. The median pretreatment PSA was 9.4 (range, 4.5-14.3) ng/mL. All patients completed the planned therapy. Acute Grade 1 toxicity was observed in 18 patients, genitourinary (GU) in 12 / 26 patients, and gastrointestinal (GI) in 6 / 26 patients. Acute Grade 2 GU toxicity was reported in 1 / 26 patients, and Grade 2 GI toxicity was observed in 2 / 26 patients. The median PSA nadir was 0.15 (range, 0.02 ¼ 1.4) ng/mL. Late toxicities were observed in 5 / 26 patients: Grade 1 GU (3 of 26), Grade 2 GU (1 of 26), and Grade 1 GI (1 of 26). Median follow-up was 21.5 (range, 8-65) months. Conclusions: Our preliminary results of SBRT ''simulating'' HDR for LpC confirm a minimal toxicity and an optimal PSA response. The PSA nadirs appear comparable with HDR-BRT.

The most effective of the three methods for pain control we used was intrarectal local anesthetic administration and lidocaine local spray 15% that enables an ideal patient comfort.
