@jeffmarc They can do an accurate Decipher on biopsy material over a year old?
Or are you suggesting a new biopsy on an already irradiated prostate?

The biopsy material is frozen, sliced into thin sections and put on slides. They can last many years. I don’t think one year would be a problem three or four might be.
From AI
To do a Decipher test for prostate cancer, labs need a sample of your actual prostate tumor tissue, usually a Formalin-Fixed Paraffin-Embedded (FFPE) block or unstained slides from a previous biopsy or surgical removal (prostatectomy), containing enough tumor cells (around 0.5mm for biopsy). They don't need new samples; they use existing pathology materials, along with the required physician forms, to perform genomic analysis on the cancer's genes to predict aggressiveness.
