We investigated the prognostic value of some variables of effective ketoconazole treatment for metastatic castration-resistant prostate cancer (mCRPC). In total, 163 patients with mCRPC were eligible, receiving ketoconazole 200-400 mg three times daily with replacement doses of prednisone. Progression-free survival (PFS) was calculated from the beginning of the ketoconazole therapy to the onset...

OBJECTIVES To present the results of a prospective phase IIa study assessing the role of primary zonal High Intensity Focused Ultrasound (HIFU) for prostate cancer treatment. METHODS 31 consecutive patients with unilateral organ confined prostate cancer primarily treated by zonal HIFU (from February 2007 to June 2011) were recruited into a single centre prospective phase IIa feasibility study...

BACKGROUND AND PURPOSE Treatment of intermediate and high-risk prostate cancer with a high BED has been shown to increase recurrence free survival (RFS). While high dose rate (HDR) brachytherapy, given as a boost is effective in delivering a high BED, many patients are not candidates for the procedure or wish to avoid an invasive procedure. We evaluated the use of stereotactic body radiotherapy...

At the time of diagnosis, prostate cancer is organ confined in 70% of the cases. A quarter of these patients undergo local therapy (surgery/radiation); 75% risk disease progression by "watchful waiting" or systemic side effects through hormonal ablation. Local high-intensity focused ultrasound (HIFU), as minimal invasive tissue coagulation (85 degrees C), ablates prostatic tissue with high prec...

In 1996 the American Society for Therapeutic Radiology and Oncology (ASTRO) sponsored a Consensus Conference to establish a definition of biochemical failure after external beam radiotherapy (EBRT). The ASTRO definition defined prostate specific antigen (PSA) failure as occurring after three consecutive PSA rises after a nadir with the date of failure as the point halfway between the nadir date...

BACKGROUND The objective of this study was to evaluate the safety, feasibility, side-effect profile, and proof of concept for focal salvage therapy using high-intensity focused ultrasound (HIFU). METHODS A registry-based analysis was conducted between 2004 and 2009 of 430 patients who underwent HIFU. Thirty-nine patients received focal salvage therapy for localized recurrence after external b...

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 p...

PURPOSE The value of total transurethral resection of prostate cancer (TURPC) as an alternative therapy was first recognized by Hans J. Reuter. Thus, we conducted the study of prospectively collected data to verify total TURPC as an alternative therapy forlocalized prostate cancer. METHODS From January 2008 to July 2011, 14 patients with a mean age of 76.1 years (range, 66 to 89 years) with c...

We investigated the potential value of prostate-specific antigen half-life (PSAHL) and decreasing velocity (PSAVd) to predict progression-free survival (PFS) and overall survival (OS) in Chinese patients with prostate cancer. A total of 153 patients treated with hormonal therapy were included in the study. Of these, 78 patients progressed to hormone-refractory prostate cancer (HRPC) and 24 pati...

OBJECTIVE The present study was done to investigate the effects of supersensitive PSA-controlled inductive treatment on positive margins, detection of tumor and epithelial cells in bone marrow of 101 patients with untreated and clinically localized prostatic carcinoma (cT1-3N0M0). METHODS Hormonal treatment was given until PSA (DPD Immulite(R) third-generation assay) reached <0.1 ng/ml or the...
