There is an error in final paragraph of the Discussion. The correct sentence is:

In summary, low concentration of spermine and high tChoCre/Spm ratio, determined by HR-MAS MRS of prostate cancer tissue, were associated with shorter time to recurrence.

The results are correctly described throughout the rest of the manuscript, but in this sentence the words ‘low’ and ‘high’ were used incorrectly.
