Project description:There is a need to understand genetic and lifestyle factors that may influence the risk of cancer progression in men who have organ-confined prostate cancer and have chosen a programme of 'active surveillance' as opposed to radical treatment with the associated health risks. Epidemiological studies have suggested that consumption of cruciferous vegetables is associated with reduced risk of developing aggressive prostate cancer. In this study we recruited men on active surveillance for low- to intermediate-risk prostate cancer to determine whether a 12-month dietary intervention can elicit transcriptional or nmetabolic responses in their prostate that would be consistent with a reduction in the risk of progression. We undertook RNAseq on prostate biopsies collected before and after a 12-month intervention with broccoli soups.
Project description:The dataset consists of 266 NCCN very low/low or favorable-intermediate risk PCa patients who underwent diagnostic prostate biopsy between 2000 and 2014 and were treated with RP in six community or academic practices: University of Calgary, Cedars-Sinai, Spectrum Health, Cleveland Clinic, MD Anderson Cancer Center and Johns Hopkins. All patients had complete tumor pathology from biopsy and prostatectomy. Low risk PCa was defined as T1c or cT2a, and Gleason score (GS) ≤ 6, and PSA < 10ng/ml and favorable-intermediate risk was no greater than predominant GS 3 and percent positive biopsy cores < 50%, and either cT2b-cT2c or PSA 10-20ng/ml.

Project description:Untargeted metabolomics analyses were performed on clinically matched baseline plasma samples (n = 16 per group) prospectively collected from patients with clinically low-risk early stage prostate cancer undergoing AS who exhibited early disease progression (DP) (defined as upgrading of Gleason score (GS) and/or increased tumor volume on surveillance biopsy within 18 months after start of AS) or indolent disease (no progression for five or more years after start of AS) as well as 459 baseline plasma samples prospectively collected from patients with early-stage prostate cancer undergoing AS.
