In Jan 2007, my 76 years old father was diagnosed with aggressive prostate cancer (PSA 197, Gleason 9 (4+5), no tertiary pattern. Ultra sound says "Prostate 100gram would account for PSA of 12.1 but not 197". Metastasis not seen but presumed for treatment purposes Note says "lymph/vascular invasion: suspicious but not confirmed " This was treated with external beam radiation (about 5 -6 months, 43 sessions) and hormone therapy (ongoing to present). PSA dropped below 1 post treatment for 18 months and then started rising over 6 months, now at 7 or 9. Is this a likely recurrence? Or possibly OK as long as PSA is under 12.1?
