Randomized Controlled Trial Multicenter Study Comparative Study
Phase I study of concurrent weekly docetaxel, high-dose intensity-modulated radiation therapy (IMRT) and androgen-deprivation therapy (ADT) for high-risk prostate cancer.
Study Type - Therapy (phase 1) Level of Evidence 2a What's known on the subject? and What does the study add? High-risk and locally advanced prostate cancers are difficult to cure with the standard regimen of radiation therapy (RT) with concurrent androgen-deprivation therapy (ADT). Multiple studies have explored the addition of docetaxel chemotherapy in attempt to improve patient outcomes. Prior Phase I studies have shown that docetaxel 20 mg/m(2) is a safe dose, when given concurrently with 70 Gy of radiation. But current standard RT for prostate cancer uses higher doses, and it is unclear if concurrent chemotherapy is safe with modern RT. This is a Phase I study that explored the addition of concurrent docetaxel chemotherapy to modern RT (intensity-modulated RT to 78 Gy) plus ADT. The study showed that weekly docetaxel at 20 mg/m(2) is safe with modern RT. At a median follow-up of 2.2 years, biochemical progression-free survival was 94%. This triple-therapy regimen is safe and promising for further evaluation in prospective trials. ⋯ • A dose of 20 mg/m(2) of weekly docetaxel given concurrently with high-dose IMRT and ADT appears safe for further study in patients with high-risk prostate cancer.

Randomized Controlled Trial Multicenter Study Comparative Study
Ability of C-reactive protein to complement multiple prognostic classifiers in men with metastatic castration resistant prostate cancer receiving docetaxel-based chemotherapy.
What's known on the subject? and What does the study add? Serum C-reactive protein (C-reactive protein) is emerging as a potential novel prognostic factor in metastatic castration-resistant prostate cancer (mCRPC). In the present study, a prospective trial was investigated retrospectively and a significant prognostic impact for C-reactive protein that was independent of multiple published prognostic models was identified in men receiving docetaxel-based chemotherapy for mCRPC. Prospective validation is warranted. ⋯ • Current prognostic classifications provide modest discrimination of outcomes in mCRPC receiving docetaxel-based chemotherapy, highlighting the need for improved risk-based models. • Baseline C-reactive protein appears to be an useful, independent prognostic factor and prospective external validation is warranted.

Randomized Controlled Trial Multicenter Study
Long-term radical prostatectomy outcomes among participants from the European Randomized Study of Screening for Prostate Cancer (ERSPC) Rotterdam.
Study Type--Therapy (cohort) Level of Evidence 2b. What's known on the subject? and What does the study add? Radical prostatectomy was previously shown to improve long-term outcomes among men with clinically-detected prostate cancer. Our data suggests that radical prostatectomy is also associated with improved outcomes in men with screen-detected prostate cancer. ⋯ • After RP, screen-detected cases had significantly improved PFS, MFS and CSS compared with controls within the available follow-up time. • The screening arm remained significantly associated with lower rates of biochemical recurrence and metastasis after adjusting for other preoperative variables. • However, considering also RP pathology, the improved outcomes in the screening group appeared to be mediated by a significantly lower tumour volume.

Multicenter Study Comparative Study
Comparison of 90-day re-admission rates between open retropubic radical prostatectomy (RRP), laparoscopic RP (LRP) and robot-assisted laparoscopic prostatectomy (RALP).
Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? With the increased use of laparoscopic radical prostatectomy (LRP) and robot-assisted laparoscopic prostatectomy (RALP), a growing number of publications have sought to compare these more advanced techniques to retropubic RP (RRP). Many studies have found RALP and LRP to be associated with lower blood loss, postoperative pain, and hospital stay when compared with RRP. The present study showed that, after adjusting for potential confounders, patients undergoing RALP had a lower risk of 90-day re-admission than patients undergoing RRP. However, there was no significant difference in the odds of being re-admitted ≤ 90 days after RP between patients undergoing a LRP and RRP. ⋯ • Our study shows that patients undergoing a RALP had a lower adjusted risk of 90-day re-admission than patients undergoing RRP. However, no significant differences were identified between LRP and RRP.

Randomized Controlled Trial Multicenter Study
Critical role of prostate biopsy mortality in the number of years of life gained and lost within a prostate cancer screening programme.
Study Type--Therapy (data synthesis) Level of Evidence 2b. What's known on the subject? and What does the study add? The efficacy of prostate cancer screening using PSA testing is still being debated, with conflicting results in randomized trials. The study shows that, even using the hypothesis most favourable to prostate cancer screening with PSA, the net number of years of life does not favour screening. ⋯ • Overall, PSA testing in Europe is associated with a loss in years of life and should thus not be recommended.
