Myelodysplastic Syndromes

Austin KulasekararajSlide2

Background and Why?

Described in 1900

Defined as MDS only in 1982-abnormal clone (don’t think it spreads like breast cancer)

No interest in studying MDS

New research, novel treatments and more emphasis on disease biologySlide3

What does the term "myelodysplastic" actually mean?

Myelo

= marrow

Dysplastic

= abnormal or just gone bad or funny looking

Bone marrow cells fail to make enough healthy blood cells- quantity and quality is affected.

Crowding out remaining normal cells (Cancer)Slide4

Red Blood Cells 20 trillionSlide5
Slide6

MDS features

All people with MDS have two things in common

Low count for at least 1 blood cell type (cytopenia)

Bone marrow and blood contain blood cells with an abnormal shape, size, or look.Slide7

Symptoms of MDS

Asymptomatic – abnormal blood count

Fatigue, lack of energy and shortness of breath

- caused by anaemia (low red cells)

Bruising and bleeding

- caused by low platelet cell count

Infection

- due to low numbers and/or poorly functioning white cells Slide8

Prior exposure to chemo and or radiotherapy, but 90% do not have any known exposures

Median age is @ 72 years
