From: Tumour and immune cell dynamics explain the PSA bounce after prostate cancer brachytherapy
Prostate-specific antigen values and isotope levels. Individual patient PSA values and model fits (solid line) plotted against normalised 125I levels (dotted line). Isotope levels in both patients without PSA bounce (A) and with bounce (B) show PSA reduction corresponding with the presence of 125I in the first 6 months. However, PSA dynamics during the time of bounce in (B) cannot be due to continued isotope because the PSA bounce occurs after the isotope has effectively decayed.
