Conclusions: It is not logical to lower the prostate specific ant

Conclusions: It is not logical to lower the prostate specific antigen threshold based on only the hemodilution effect since body mass index related prostate volume enlargement can increase prostate specific antigen in obese men. Another tool is needed and prostate specific antigen mass ratio may be an option.”
“Purpose: The effect of statin medication use on the risk of prostate cancer is unknown.

Materials and Methods: We examined data from a longitudinal, population based cohort of 2,447 men between 40 and 79 years old who were followed from 1990 to 2007. Information on statin mTOR inhibitor use was self-reported and obtained by biennial questionnaires. A randomly

selected subset of men (634, 26%) completed biennial urological examinations that included serum prostate specific antigen measurements. Information on prostate biopsy and prostate cancer was obtained through review of community medical records.

Results: Of 634 statin users 38 (6%) were diagnosed with prostate cancer vs 186 (10%) of 1,813 nonstatin users. Statin use was associated with a decreased risk of undergoing prostate biopsy (HR 0.31; 95% CI 0.24, 0.40), receiving a prostate cancer diagnosis (HR 0.36; 95% CI 0.25, 0.53) and receiving a high grade (Gleason 7 or greater) prostate cancer diagnosis (HR 0.25; 95% CI 0.11, 0.58). Statin use was also associated with a nonsignificantly decreased risk of exceeding

a prostate specific antigen threshold of 4.0 ng/ml (HR 0.63; 95% CI 0,35, 1.13). In addition, a longer duration of statin use was associated with a lower risk of these outcomes (all tests for trend p <0.05).

Conclusions:

“Purpose: Five genetic variants along chromosomes 8q24 and 17q have a cumulative association with prostate cancer risk. Our research group previously reported an association between these variants and clinicopathological characteristics. More recently 4 additional prostate cancer susceptibility variants were identified on chromosomes 2p15, 10q11, 11q13 and Xp11. We performed Selleckchem Quizartinib cumulative risk assessment incorporating all 9 genetic variants and determined the relationship of the new variants to clinicopathological tumor features.

Materials and Methods: The genotype of 9 variants was determined in 687 men of European ancestry who underwent radical prostatectomy from 2002 to 2008 and in 777 healthy volunteer controls. We compared the incidence of these variants in prostate cancer cases and controls, and assessed their cumulative risk. We also determined the relationship of carrier status for the 4 new variants and clinicopathological tumor features.

Results: Prostate cancer cases had an increased incidence of all 9 risk variants compared to controls.
