Compilation of polymorphisms being investigated for a role in 02 prostate carcinogenesis. Using only 28 prospective studies- randomized or cohort they reviewed the dietary evidence for 29 prostate cancer associations. The x axis gives the number of studies reporting either 30 inverse, null or positive associations on the y axis with particular dietary component 31 (Dagnelie et al. Other dietary factors were inconclusive, though high levels 36 of calcium [>2000 mg/day] appeared to be adverse (Dagnelie et al.

Aspirin and non-steroidal 31 anti inflammatory drug consumption has had mixed results as to whether there 32 is a null or modest protective association (Habel et al. The primary endpoint of lung 02 cancer prevention was not realized, in the beta carotene arm there were more lung 03 and prostate cancers with a higher total mortality of 8%. In the alpha-tocopherol 04 [Vitamin E] arm but there was a reduction in prostate cancer, 99 versus 151 cases, 05 a reduction by approximately one third [34%]. Hemorrhagic strokes 07 in men with uncontrolled hypertension contributed to the higher mortality in the 08 vitamin E arm, there was a 45% increased risk during the trial (Albanes et al. In a post trial analysis there was a persistent protective effect of vitamin E 10 on prostate cancer after intervention, but diminished fairly rapidly- by the third year 11 (Virtamo et al. Finasteride has been used to treat bladder outlet obstruction from 02 prostate enlargement since 1992. The trial was 06 closed early as the primary endpoint of 25% prostate cancer reduction was achieved 07 in the arm treated with finasteride.
