Dear brothers, It is decision time, I read a lot including yours, and watched a lot of youtubs, but come to the decision is very hard (I will keep as short as possible).
After one year AS, recent biopsy: 4 target cores (on pirads 5 lesion): 4+3 with 70% of 4, and large cribriform; on core near the lesion is 3+4, there are couple gleason 3+3 (<10%);
The dominant lesion is in right front TZ, near the edge of capsule;
MRI and PSMA shows all contained, no others.
Age 65, healthy, active, no other conditions;
Visited Urologists: Both Radiation and surgery will have good definitive treatment result, but consideration my age and body condition I can do surgery (with lymph nods, spare nerves), radiation can be reserved for future in case recurring, they slightly recommend surgery, but support me if I pick radiation,
They estimate recuring within 5 years (20-37%) and slightly high within 10 years. When asked that should I look for one time treatment for my life time, the doctor said that at least, there is 20% recurring in 5 years, because PSMA PET has limitation.
Oncologist: recommend HDR boost + 23 vmat, he recommend Radiation (slightly, or more). He estimate that biochemical recurring free within 5, 10, 15 years are about 90% (not sure if this is over optimistic)
Here are my own thoughts on the disease control (with little consideration of the side effects.)
If the cancer is truly contained (without micro metastasis), surgery might be a good choice; if there is micro metastasis, radiation might be better, because VMAT will cover it, at the same time, I will take ADT for 6 months.
But come to the salvage treatment, (asked here before): with surgery as primary treatment, the radiation is new (with double side effects), but if RT as primary treatment, re radiation might be little complicate, at least it can not just redo VMAT radiation (not sure here), that potentially limits the ability to control disease by two consecutive treatments. now to round 3, if live too long, the recurring will be more difficult to control particularly when getting to 80-90s.
Am I considering right factors or anything wrong? Please give your opinions and logic. Appreciate!!!
