Hi, @pmm - what to do if the hematologists/oncologists at your clinic "don't treat MGUS"?
I was recently diagnosed with MGUS at Mayo Clinic. It seems to be kappa light-chain MGUS from comparing my test results to my extensive reading.
FLC ratio is 5.64, bone marrow was 5% abnormal kappa plasma cells, mutation from FISH testing was t(11;14)(q13;32).
I had pushed for further testing due to the LC ratio and so got fat pad and bone marrow biopsies done. The internal medicine doc handling this was commendably open to my concerns about progressing to AL amyloidosis, given my presenting symptom of somewhat rapidly-progressing length-dependent axonal peripheral neuropathy.
But I have not spoken with a hem/onc because "this is only MGUS". Rather, a hem/onc was called as a consult to my doctor, not to me. Fortunately he did agree to the bone marrow biopsy with FISH analysis and ordered it, so now I have a better picture of what's going on.
Because my abnormal plasma cells are only at 5% and my light chains are relatively low, though with an abnormal ratio, and no amyloids were found by biopsy, I've been advised to wait 6 months and test again. But what about the peripheral neuropathy? It started at the bottoms of my feet in July, approximately, and had progressed to the top of my knees by November.
For my own peace of mind, I found a local lab where I can get the FLC test run for under $200 self-pay, so I can check that before having to wait 6 more months to check whether there's progression.
