Letter to the editor regarding the publication “Association between matrix-metalloproteinase polymorphisms and prostate cancer risk: A metaanalysis and systematic review”

The authors of the article, “Association between matrix-metalloproteinase polymorphisms and prostate cancer risk: a meta-analysis and systematic review”, Zhou et al, have put forth a number of interesting points.1 This paper, published in the journal Cancer Management and Research attempts to link matrix metalloproteinase (MMP) polymorphisms and the propensity to developing prostate cancer. Though a similar study has previously been done on ovarian cancer by authors credited in this study, this study does tread fresh ground on the topic of prostate cancer and has potential to act as a guideline for future research.
