9 Environmental exposition
42-year-old nurse presenting with severe sideroblastic anemia She used a caraff from the island of Samos, Greece for juice. Lead-containing glaze burnt at suboptimal temperature. Large quantities of lead release into juice, and ingested by patient Hellström Lindberg, Int Arch Occup Environ Health (2):165-8.

10 Vanliga debutsymptom vid MDS
Ibland inga symptom Ofta smygande start Trötthet, uttröttbarhet Andfåddhet, minskad fysisk prestationsförmåga OBS noggrann anamnes hos äldre Blåmärken, blödningar Infektioner

11 Ibland akut presentation
Svår infektion Blödning Trombocytopeni DIC

12 Inflammatoriska symptom
Ses hos ca 10% av MDS Skala från SR stegring utan symptom till svår generell inflammation Kan påverka olika organ Vanligare vid högrisk MDS ofta dispyt med reumatologer om inflammationen är hönan eller ägget Behandling Steroider / immunosuppression Behandling av MDS klonen Saif, Leukemia & Lymphoma 2002 and Bouali, Rev Med Intern 2005

13 Sweet syndrom - acute neutrophilic dermatosis
Buck, Int J Dermatol 2008

14 Sweet syndrom - pyoderma gangrenosum (PG)
Avivi, Leuk Res. 1999 Buck, Int J Dermatol 2008

15 Konstitutionella symptom
Ganska vanligt vid CMML och “mixed MDS/MPN, unclassifiable” Förekommer vid andra typer av MDS “B-symptom” Splenomegali (oftast CMML) Behöver inte alltid vara tecken på högrisk sjukdom Neukirchen, 2900 pts, Eur J Hematol 2009

16 Blödning Måttligt förhöjt APTT utan symptom är ganska vanligt vid CMML
Allvarlig koagulationsrubbning kan förekomma vid högrisk sjukdom Blödningsbenägenhet behöver inte vara direkt kopplat till trombocyttal Germing et al, Haematologica 2007

17 MDS (?) responding to IS Woman born 1963, second opinion in Autoimmune disorders in family Onset of anemia, high SR, leg pain in 2004 BM TLD, erythroid hyperplasia, cellularity 70%, fibrosis, 46XX. RCMD with fibrosis Rheumatology work-up – “must be paramalignant” ATG in 2007 & 2008, normal Hb, decreased inflammation 2009 relapse in anemia - cyclosporin A restarted 2015, slight leg pain, normal blood values, less fibrosis in BM and in full activity Maintains a low dose CsA

20 WHO Classification for MDS 2008
Refractory cytopenia with unilineage dysplasia Refractory anemia with RS Refractory cytopenia with multilineage dysplasia +/- RS Refractory anemia with excess blasts (RAEB-1, 5-9% / RAEB-2 ≥10%) MDS-unclassified MDS with isolated del(5q) and BM blasts <5% Cazzola et al., Hematol Clin Oncol North Am 2010

21 WHO classification of myelodysplastic / myeloproliferative neoplasms
Chronic myelomonocytic leukemia (CMML) Atypical chronic myeloid leukemia, BCR-ABL1 neg Juvenile myelomonocytic leukemia MDS/MPN, unclassifiable RARS associated with marked thrombocytosis Dysplasia. Ph neg. Monocytes >109/l for >3 months, marrow/blood blasts 0-20% Dysplasia. Ph neg. Myeloid non-monocytoid, non-basophil proliferation, marrow/blood blasts 0-20% 0-14 years. Dysplasia. Ph neg. WBC>10, Monocytes >109/l, marrow/blood blasts 0-20%, often monosomy 7 Mix of dysplastic and proliferative features, not fulfilling criteria above Provisional entity, RARS-T

22 Terapirelaterad MDS 10% av MDS, internationellt och i INCA registret
Oftast cytostatika (alkylerare, antracycliner, övriga) Strålbehandling, men ovanligt vid isolerad strålning över begränsade fält Vanligen 2-7 år efter primärbehandling Beslut om “tMDS” konsensusbedömning diagnostik-klinik Fianchi et al, J Hematol Oncol 2012, Klimek, Leuk Res 2012 Quintas-Cardama A, Blood 2011;118(Suppl. 1): Abstract 967.

23 Typfall 55-årig man, behandlad pga Hodgkins sjukdom för 3 år sedan, CR. Långsamt sjunkande blodvärden, fr a neutrofiler (0,2) och trc (50). RCMD, 4% blaster, karyotyp 45, XY, -7, +15. 70-årig kvinna med myelom sedan 3 år, tredjelinjens behandling med lenalidomide. Sjuknande blodvärden under 3 månder, nu grav pancytopeni och blödningar. RAEB-2,10% plasmacller i BM, gravt komplex karyotyp inkluderande del(5q), -6, -7, -11, -13, del(17p) 75-årig kvinna behandlad för bröstcancer med op och strålning for 20 år sedan. Macrocytär anemi, RARS, normal karyotyp. Fianchi et al, J Hematol Oncol 2012, Klimek, Leuk Res 2012 Quintas-Cardama A, Blood 2011;118(Suppl. 1): Abstract 967.

24 Terapirelaterad MDS WHO klassifikationen ganska fyrkantig; tMDS och tAML sammanförs till en kategori Dock; vanliga riskkriterier lika viktiga vid tMDS som vid de novo MDS. NMDSG och INCA rekommenerar att klassa enligt de novo MDS men ange “tMDS” som sannolik orsak Fianchi et al, J Hematol Oncol 2012, Klimek, Leuk Res 2012 Quintas-Cardama A, Blood 2011;118(Suppl. 1): Abstract 967.

25 Riskbedömning vid MDS Förväntad överlevnad AML transformation
Komplikationer till cytopeni Sannolikhet att svara på olika behandlingar Fianchi et al, J Hematol Oncol 2012, Klimek, Leuk Res 2012 Quintas-Cardama A, Blood 2011;118(Suppl. 1): Abstract 967.

26 Kromosomer vid MDS 50-60% av MDS uppvisar kromosomförändringar
40-50% har normal karyotyp Vanligare hos RARS och CMML Vanligaste förändringarna isolerad del(5q) > monosomi 7 > trisomi 8 -Y räknas som klonal förändring om klonen är dominant Komplex karyotyp också vanligt (≥3 aberrationer) Enligt IPSS-R är ≥4 sämre än ≥3 Enligt IPSS-R ger –Y och del(11q) bättre prognos än normal karyotyp Stark relation till mutationer

37 Multiprofessionella konferenser
MDS är en klinisk diagnos som kräver input från olika professioner Anamnes (familjehistoria, exposition, andra orsaker till cytopeni, etc) Morfologi och histopatologi Cytogenetik, mutationsanalys Detta leder till WHO diagnos IPSS och IPSS-R score / risk grupp Information om prognos och behandling Behandlingsbeslut inklusive expektans, transfusioner och SCT Registrering I INCA
