via MedWire News – Oncology – PCA3 predicts prostate tumor volume and could indicate AS suitability.
I have been using PCA3 tests to estimate tumor burden for men choosing active surveillance for about 2 years. I also check a PCA3 test after some time for men on active surveillance. The values that are considered to be significant will need to be studied.
