Monoclonal immunoglobulin or free light chains can be present
What affect does multiple myeloma have on the body - what does it affect?
1) Bone marrow failure
2) Renal failure
3) Destructive bone disease
4) Hypercalcaemia
Why are bones affected in Multiple Myeloma?
1) Rapid growth of myeloma cells inhibits osteoblast formation
2) Myeloma cells release OAFs that stimulate osteoclasts - reducing bone

2) <10% plasma cell in bone marrow
What is asymptomatic myeloma criteria?
1) >10% plasma cells in bone marrow
2) No related organ or tissue involvement
What are the clinical entities of symptomatic myeloma?
1) Paraprotein
2) Clonal plasma cells in bone marrow
3) Related organ or tissue involvement

1) Lump e.g. in the neck or arm
2) Compression syndrome - blood supply compression leads to oedema
3) B type systemic symptoms - loss of weight, loss of appetite and night sweats
How is Lymphoma diagnosed?
1) Blood film
2) Bone marrow biopsy
3) Lymph node biopsy
4) Immunophenotyping - CD markers
5) Cytogenetics
