Study Type--Therapy (cohort) Level of Evidence 2a. What's known on the subject? and What does the study add? Patient-reported quality of life (QoL) in prostate cancer is recognized as an important outcome, and has been shown in multiple studies to capture the incidence and timing of patient symptoms more accurately than physician-graded toxicity reports. Although the long-term QoL after completing radiation therapy (RT) has been previously studied, patient experience during RT is not well described in the literature. The present study collected patient-reported QoL during RT in a prospective phase II clinical trial. The study describes in detail the time course and severity of gastrointestinal and genitourinary symptoms during radiation, providing clinically useful information for patients and physicians considering RT during the treatment decision-making process. ⋯ • Urinary symptoms were common during RT, and bowel symptoms were less frequent. • These results inform patients and physicians during the decision-making process about potential patient quality of life experiences during RT, and also provide a benchmark for comparative effectiveness studies against newer treatments and technologies.

What's known on the subject? and What does the study add? In spite of its low specificity, PSA is the most widely used screening test for prostate cancer (PCa), and is considered the main cause of the stage migration recently observed. The ratio of free to total PSA (%fPSA) has been shown to increase PSA accuracy in cancer detection; however, few screening studies have systematically evaluated its role in cancer detection rates in men with PSA levels <4.0 ng/mL and normal DRE. The present study supports a possible role of %fPSA as an adjunct to screening in men with total PSA 2.5-4.0 ng/mL and normal DRE, with a marked increase in cancer detection rates in a large Brazilian PCa screening study. We believe that %fPSA maybe a useful refinement to biopsy indications in men with low PSA levels. ⋯ • The use of %fPSA ≤ 15 as a biopsy indication in men with normal DRE and PSA 2.5-4.0 ng/mL in a PCa screening programme, increased cancer detection rates. Tumours in this subset of patients had similar pathological characteristics. • Using %fPSA ≤ 15 to indicate biopsy in men with PSA 2.5-3.9 ng/mL is a useful adjunct to PCa screening.

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
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.

Randomized Controlled Trial Multicenter Study Comparative Study
Androgen deprivation therapy for volume reduction, lower urinary tract symptom relief and quality of life improvement in patients with prostate cancer: degarelix vs goserelin plus bicalutamide.
Study Type--Therapy (RCT) Level of Evidence 1b. What's known on the subject? and What does the study add? Androgen deprivation therapy (ADT) is commonly used as a primary treatment for patients with prostate cancer (PCa) who are not eligible for radical treatment options. ADT is also used in patients with PCa as neo-adjuvant hormone therapy to reduce prostate volume and down-stage the disease before radiotherapy with curative intent. The present study showed that ADT with the gonadotropin hormone-releasing hormone (GhRH) antagonist degarelix is non-inferior to combined treatment with the LHRH agonist goserelin and bicalutamide in terms of reducing prostate volume during the treatment period of 3 months. Degarelix treatment evokes, however, significantly better relief of lower urinary tract symptoms in patients having moderate and severe voiding problems. ⋯ • Medical castration reduces TPV and could also improve LUTS in patients with PCa. • While the short-term efficacy of degarelix and goserelin + bicalutamide was the same in terms of TPV reduction, degarelix showed superiority in LUTS relief in symptomatic patients, which could highlight the different actions of these drugs on extrapituitary gonadotrophin-releasing hormone (GnRH) receptors in the bladder and/or the prostate.
