Definition of biochemical failure:
After primary RT, with or without short-term hormonal manipulation, the RTOG-ASTRO Phoenix Consensus Conference definition of PSA failure (with an accuracy of > 80%) is any PSA increase > 2 ng/mL higher than the PSA nadir value, regardless of the serum concentration of the nadir.
Your nadir seems to be 0.3 and your most recent PSA is 0.8 - so not a failure yet!
