Effect of statins on survival not evident in new meta-analysis ? THE ...

A new meta-analysis has (once again) demonstrated that statin therapy does not appear to be associated with a survival benefit in men who have received first-line treatment for prostate cancer with surgery or radiation therapy.

This new paper (by Scosyrev et al.) in BJU International seems to confirm an earlier meta-analysis by Bonovas et al. (published in 2008) which came to comparable conclusions.

The core data from the new paper are as follows:

  • The meta-analysis was based on data from eight primary studies.
    • Five of the primary studies were based on radical prostatectomy (RP) patient series
    • Three were based on radiotherapy (RT) patient series.
    • The eight studies included 2,812 statin users and 10,031 statin non-users.
  • Pooled estimates of the hazard ratios (HRs) for the risk of biochemical recurrence in statin users vs. statin non-users were
    • 0.91 for the whole set of all eight studies
    • 1.02 for the RP series
    • 0.71 for the RT series

However, there was distinct evidence of heterogeneity

  • Across the whole set of eight studies (P = 0.002)
  • Within the RP series (P = 0.05)
  • Within the RT series (P = 0.01)

What?s the bottom line?

Well it certainly looks as though we are going to need a series of carefully conducted, 20-year-long, randomized, double-blind trials to really discover whether taking a statin affects survival after initial treatment for prostate cancer. ? And what do think the chances of that happening are in our currently depleted economy? (That is not, we hasten to add, any sort of snide political comment.)
