When sent to Bostwick we thought they were doing other tests but none had been done.
I'm no expert, but I think some special staining is required. In reading about
one type of rare cancer, it says, "Immunohistochemistry can be useful in identifying this malignancy, with CD-56 staining positive in 92% of cases and synaptophysin positive in 85% of cases, which is helpful in discriminating this tumor from poorly differentiated acinar adenocarcinoma (Gleason 5)" Perhaps the pathologist has to suspect what he's looking for in order to find it.

They even make us choose bone scan, MRI or PET scan. Not a combo.... Really strange.
The PET scan comes with a CT scan. (The new models come with MRI instead.) That is the best indicator available. I know I asked before, but I forgot your answer - did you look into Dr. Schuster's FACBC PET at Emory? If that wasn't possible, you might be able to get him a free PET at NIH, and they cover all travel expenses too. This is the one Sonny and Wampuscats had - he might be eligible for Arm 3. Contact:

Do you think knowing he has the BRCA genes makes any difference in any treatment plan?
Do you have reason to believe he might? It's a relatively rare occurrence, so unless he has a family history that clearly points in that direction (e.g., mother dying young of breast cancer, relatives with multiple cancers), I don't think it's worth the outlay of $3000 or so (insurance seldom covers this for anybody). If you do have reason to believe he might and want to come up with the money, there are clinical trials for PARP1 inhibitors, like olaparib, that he might qualify for.
My hunch is that it's much more likely that his cancer is positive for the growth hormone receptor. Special Lady had a doctor's name in Germany who could do the relatively inexpensive test, but there must be labs in the US that can do it, or possibly even the lab at Emory. If so, he may respond to therapy with pasireotide,octreotide,lanreotide, or Somavert.

but I have not seen one iota of solid proof of anything but prostate involvement.
A biopsy would be ideal, but lacking that, there is something else that can be done. It's called "CellSearch" and it counts the number of circulating tumor cells in the bloodstream. When there are more than 5, it's prognostic for systemic disease (although there can be false negatives). Here's a link for the test that has a number you can call, and you can ask if insurance covers it:
