Summary

The purpose of this study is to evaluate the effectiveness of the two most established primary treatments for patients with clinically localized prostate cancer: radical retropubic prostatectomy, and external-beam radiotherapy. The primary aim is assessing biochemical disease-free survival, overall survival, and prostate cancer-specific survival. As secondary objectives quality of Life impact of treatments' side effects will be also assessed.

Detailed description

Eligible patients had clinically localized (clinical TNM classification T1 or T2), biopsy-proven adenocarcinoma of the prostate and were randomly treated with RRP or EBRT. Exclusion criteria included prior treatment for prostate cancer, the presence of metastatic disease on imaging studies, the receipt of neoadjuvant androgen ablation before registration, and an inability to read or understand Italian language. The institutional review boards of every participating centre approved the study design. Every patient enrolled signed an informed-consent form approved by the institutional review boards. Clinical information collected from the medical record included pre-treatment serum prostate-specific antigen (PSA) level, clinical T classification, and biopsy Gleason score. Follow-up assessments were completed before treatment and every 3 months after treatment. Subjects who sought primary treatment elsewhere or did not return follow-up questionnaires beyond the initial assessment were excluded from this analysis.

Type	Name	Description
PROCEDURE	Radical retropubic prostatectomy	The surgery arm underwent radical retropubic prostatectomy, performed by a technique described by Walsh. The prostatectomy is performed in retrograde way, preserving the neurovascular bundles if feasible. The degree to which the surgeon preserve the nerves is categorized as non-nerve-sparing, unilateral nerve-sparing, or bilateral nerve-sparing. Pelvic lymph node dissection is performed if feasible. The operative time is about 2 to 3 hours and required hospital stay. The patient has a urinary catheter placed for 6 to 9 days to facilitate bladder emptying.
RADIATION	External beam radiotherapy	External beam radiotherapy is carried out with intensity-modulated radiation technique. The treatment is designed to maximize the radiation dose to the prostate and seminal vesicles and minimize exposure to surrounding structures, including the bladder and rectum. Radiation to the prostate was delivered in fractionated doses divided over multiple treatments (180 to 200 centigray (cGy) daily fractions, 5 days per week) for a total dose to the prostate of 68 to 77 gray (Gy), prescribed at 90% to 100% of the isodose line.
