New
research on the genetic and metabolic level of prostate cancer is important
for future disease management in diagnostics, choice of treatment and
prognosis. This study describes a highly standardized method for
snap-freezing of a whole prostate slice that is safe (without interfering
with the routine diagnostics), easy to practise, and results in tissue with
highly intact molecular content suitable for ex vivo MR spectroscopy and gene
expression of the same sample. The present harvesting method is applicable to
all prostate cancer patients and stores the snap-frozen tissue without fixatives,
leaving it available for all kinds of future research technologies.
