Hello @beachdog

I appreciate you offering some perspective to the CA19-9 numbers as it relates to the progression of pancreatic cancer. You provided some great personal examples. You mentioned your wife having "chemo, sbrt. and surgery." I'm not sure what "sbrt" stands for. Can you explain?

Sbrt is focused radiation treatment. Gold fiducials are implanted in the target area of the pancreas via EUS. The fiducials are targeted during the radiation which creates a pattern like the spokes of a bicycle wheel. That way the target gets the main radiation and the rest of the body receives minimal exposure. In my wife's case, they used photon radiation and the tumor was 100% necrotic after 5 treatments. There are a limited number of facilities with the technology to perform sbrt.
