Randomized Controlled Trial Comparative Study
CheckMate 025 Randomized Phase 3 Study: Outcomes by Key Baseline Factors and Prior Therapy for Nivolumab Versus Everolimus in Advanced Renal Cell Carcinoma.
The randomized, phase 3 CheckMate 025 study of nivolumab (n=410) versus everolimus (n=411) in previously treated adults (75% male; 88% white) with advanced renal cell carcinoma (aRCC) demonstrated significantly improved overall survival (OS) and objective response rate (ORR). ⋯ We investigated the impact of demographic and pretreatment features on survival benefit and tumor response with nivolumab versus everolimus in advanced renal cell carcinoma (aRCC). Survival benefit and response were observed for multiple subgroups, supporting the use of nivolumab as a new standard of care across a broad range of patients with previously treated aRCC. The trial is registered on ClinicalTrials.gov as NCT01668784.

Review Comparative Study
Quality of Life Outcomes after Primary Treatment for Clinically Localised Prostate Cancer: A Systematic Review.
Current evidence-based management for clinically localised prostate cancer includes active surveillance, surgery, external beam radiotherapy (EBRT) and brachytherapy. The impact of these treatment modalities on quality of life (QoL) is uncertain. ⋯ Our review of the current evidence suggests that for a period of up to 6 yr after treatment, men with localised prostate cancer who were managed with active surveillance reported high levels of quality of life (QoL). Men treated with surgery reported mainly urinary and sexual problems, while those treated with external beam radiotherapy reported mainly bowel problems. Men eligible for brachytherapy reported urinary problems up to a year after therapy, but then their QoL returned gradually to as it was before treatment.

Multiparametric magnetic resonance imaging (mpMRI) is gaining widespread acceptance in prostate cancer (PC) diagnosis and improves significant PC (sPC; Gleason score≥3+4) detection. Decision making based on European Randomised Study of Screening for PC (ERSPC) risk-calculator (RC) parameters may overcome prostate-specific antigen (PSA) limitations. ⋯ Combined risk models including clinical and imaging parameters predict clinically relevant prostate cancer significantly better than clinical risk calculators and multiparametric magnetic resonance imaging alone. The risk models demonstrate a benefit in making a decision about which patient needs a biopsy and concurrently help avoid unnecessary biopsies.

Some of the high costs of robot-assisted radical prostatectomy (RARP), intensity-modulated radiotherapy (IMRT), and proton beam therapy may be offset by better outcomes or less resource use during the treatment episode. ⋯ We review the cost and cost effectiveness of robot-assisted radical prostatectomy, intensity-modulated radiotherapy, and proton beam therapy in prostate cancer treatment. These technologies are costlier than their traditional counterparts. It remains unclear whether their use is associated with improved cure and reduced morbidity, and whether the increased cost is worth the expense.
