I can't answer that question specifically. but the time limit between the debulking surgery for the metastasis on my spine and post-op SBRT radiation was a bit over a month — I suspect that's how long before there was a risk of any remaining cancer cells consolidating and the lesion growing back — but I'm just guessing. It could be an entirely different time window with your treatments.

They said I could wait up to a year on Firmagon and Erleada before getting the high dose of SBRT for the prostate itself, but I elected to do it sooner (after 6 months) because at the time COVID outbreaks were still sometimes causing hospitals to suspend outpatient services, and leaving it too long didn't seem wise
