Hi Marilyn .....
I took time to go back a re-read your previous posts on Mike's long AN journey.
You do not say if you have been consulting with Drs. Slattery/Schwartz during the discovery of the latest regrowth, but I certainly hope so.
I know you consulted with Dr. Friedman in the past. If you have not already contacted him, I would for another opinion, because USC has a very multi-faceted approach to AN treatment, including dealing with regrowth using radiation, as well as surgery.
Drs. Friedman/Schwartz did my translab surgery for regrowth three years ago and I still send all of my post-op MRIs to Dr. Friedman ..... in fact, he sends the order for them to the imaging facility. I also make a 3-hr drive each time to a university medical center that has the largest Tesla MRI machine to be able to do finer cuts on the scan to see growth more quickly.
Dr. Fred Barker, from Massachusetts General, gave a talk at the ANA Symposium in LA a year ago on regrowth. Among many other things, he said that if the original tumor was a rapidly growing one (unusual for ANs), any regrowth is likely to be rapid. This seems to be Mike's case.
Regrowth is still considered extremely rare because usually any remaining tumor will die when the blood supply is cut. However, if even one cell is left from a highly active tumor, the potential for regrowth is there.
So many thoughts and prayers for both Mike and you. PM me if you would like to talk.
