Dear Suzi
I am sorry that no one, as yet, has replied to your post. It may be that no one has the experience of non – secretory myeloma. I hope you don’t mind me replying. My name is Ellen and I am one of the Myeloma Information Specialist here at Myeloma UK.
As you know, the majority of myeloma patients secrete a measurable paraprotein. Patients diagnosed with non-secretory myeloma do not produce a paraprotein; this type of myeloma is rare but is no different to secretory myeloma in terms of treatment options and how it affects the body.
The problem is the difficulty in monitoring given the absence of paraprotein in the blood. Most patients with non-secretory myeloma would therefore be monitored through regular bone marrow biopsies, close monitoring of the healthy bloods – the red cells, white cells and the platelets is also important as they can be affected by myeloma activity. It is also important for the patient to report promptly any signs or symptoms that may mean the myeloma is active those may be new or increasing pain or fatigue and recurrent infections.
A PET scan can be useful in identifying response to treatment or relapse in those patients who have non-secretory myeloma as it identifies areas of fast dividing cells and can quickly pick up changes in myeloma activity or areas of new activity. However there are other cells of the body which divide quickly and this can occasionally throw up ‘false positives’. Again this is why the patient needs to be vigilant.
I hope this has been of some help, but if you have any further questions, or would like to talk things through, please feel free to call the Myeloma Infoline on 0800 980 3332. Alternatively you can email directly to askthenurse@myeloma.org.uk and I or one of my colleagues can clarify things for you further.
With best wishes
Ellen
