Hi Pauline,
Sorry that your Dad has to walk this path. Please check my stats below. They will give you the dates and timeline of my pT3b diagnosis. I saw my urologist/surgeon, a medical oncologist/hematologist, and a radiation oncologist. The consensus was that I needed to start Adjuvant Combination Therapy as soon as possible. My positive margins were fairly extensive at the base, and the seminal vesicle involvement was the clincher for doing both Androgen Deprivation Therapy (Lupron) and IMRT. 1st Lupron injection was on Oct 20. IMRT will begin on Jan 12. My 1st PSA was at 1 month and was undectable at <0.01. 2d PSA at 2 months gave the same result. With pT3b, you don't want to wait for a rising psa to start salvage radiation therapy. Hope this helps.
Roger
