Decipher™ is the only genomic classifier that is validated for this purpose:
Genomic classifier can help identify patients who may not need adjuvant radiationBut it costs around $4,000 - check with your insurance first. It's only good at predicting who
doesn't need adjuvant radiation, but it's not so good in predicting who does need it. So if your GC score is, say 0.4 (most guys have scores of about
that), it gives you no more decision-making guidance than you have now.
A recent study showed that PSA≥0.03 predicts recurrence, and treatment after waiting for that point (early salvage)has no worse outcomes compared to adjuvant radiation. There's no advantage to jumping the gun.
When should the patient and doctor consider salvage radiation therapy?- Allen
