Q. How fast can primary amyloidosis spread? And what is the average survival rate for this disease?

A. Your best bet for one-stop shopping for amyloidosis information on the net is http://www.amyloidosis.org. There is also a Yahoo group named amyloidosis and also a mailing list named amyloid hosted by the Association of Cancer Online Resources. The amyloid list has around 500 subscribers, amyloidosis Yahoo group has maybe half that many. Face-to-face support for patients and caregivers is also available in most large metropolitan areas two or three times a year. See http://www.amyloidosissupportgroups.com for details.

Q. what is the most accurate pathological test to identify the primary source of a cystic mass in the neck? the mass was removed. Pathologist was unable to identify the source and diagnosed the mass as a branchilogic carcinmoa (which is extremely rare, if exists at all). Therefore, I am looking for the most updated test and examinations that can be applied to blocks of the mass and determine their origin (primary source)

A. Pathologic examinaions under a microscope are the most accurate ones there are, and sometimes even they don't help to identify the cell types. I do not have any other ideas on other tests you can do, and I believe you should follow the treatment your doctors will advise you based on this diagnosis they have made.
