Undersøgelse af blodprøver fra nyfødte med Downs syndrom

2. oktober 2023 opdateret af: Children's Oncology Group

Biologisk undersøgelse af forbigående myeloproliferativ lidelse (TMD) hos børn med Downs syndrom (DS)

Denne forskningsundersøgelse ser på blodprøver fra nyfødte med Downs syndrom. At studere generne udtrykt i blodprøver fra patienter med Downs syndrom kan hjælpe læger med at identificere biomarkører relateret til kræft.

Detaljeret beskrivelse

PRIMÆRE MÅL:

I. At fremme vores biologiske forståelse af den naturlige historie af forbigående myeloproliferativ lidelse (TMD) og dens forhold til efterfølgende leukæmi ved at facilitere udviklingen af ​​en TMD-celle- og proteinbank og opbevaring af DNA/RNA fra megakaryoblaster til fremtidige biologiske undersøgelser.

II. At undersøge biologien af ​​TMD-molekylære ændringer forbundet med opløsning af TMD eller dets omdannelse til akut myeloid leukæmi inden for hver dødelighedsrisikogruppe ved at udføre GATA1-mutationsanalyser, hæmatopoiese klonalitetsundersøgelser, vurdering af RAS-mutationer og genomiske ustabilitetsundersøgelser ved hjælp af glycophorin A-assays.

III. For at bestemme, om højopløsnings mikroarray-genomisk analyse af TMD-blaster (ved hjælp af Affymetrix SNP Genechip-teknologi til at vurdere genekspression, kopiantal variation og tab af heterozygositet) kan forudsige udviklingen af ​​efterfølgende leukæmi.

IV. At bestemme forholdet mellem minimal resterende sygdom (overvåget af perifer blodgennemstrømningscytometri og GATA1 mutationsundersøgelser) til klinisk remissionsstatus og udvikling af efterfølgende leukæmi inden for hver mortalitetsrisikogruppe af TMD-patienter.

V. At evaluere forholdet mellem karyotype (herunder FISH-analyse) og efterfølgende leukæmi hos TMD-patienter.

VI. At undersøge farmakogenetik og in vitro lægemiddelfølsomhed over for cytarabin (MTT-assay) i blaster fra TMD-patienter.

VII. At undersøge forholdet mellem funktionelle polymorfier i fase I og fase II lægemiddelafgiftningsgener, DNA-reparation og DNA-synteseveje, der kan ændre modtageligheden for leukæmi og resultatet hos TMD-patienter.

VIII. For at bestemme forholdet mellem fibrose-associerede serumfaktorer (f.eks. blodplade-afledt vækstfaktor, transformerende vækstfaktor beta, N-terminalt peptid af III procollagen, type IV kollagen og hyaluronsyre) og begivenhedsfri overlevelse.

OVERSIGT: Dette er en multicenterundersøgelse.

Patienter gennemgår periodisk opsamling af perifert blod til biomarkøranalyse. Prøver analyseres for GATA1-mutationer ved realtids-PCR, polymorfismer, cytogenetik og K-RAS-mutationer, genekspression, lægemiddelfølsomhedsmønstre og minimal resterende sygdom ved flowcytometri.

Patienterne følges op med jævne mellemrum i 5 år.

Beskrivelse

Inklusionskriterier:

  • Diagnose af forbigående myeloproliferativ lidelse (TMD) ved < 90 dages alder og opfylder 1 af følgende kriterier:

    • En diagnose af Downs syndrom eller Downs syndrommosaicisme OG ikke-erytroide og ikke-lymfoide blaster (en hvilken som helst mængde) i det perifere blod verificeret med en anden prøve

      • Patienter med typiske fysiske karakteristika for Downs syndrom er tilladt før cytogenetisk eller FISH bekræftelse af diagnosen

    • Trisomi 21-positive leukæmiblaster dokumenteret ved biopsi af ethvert organ (inklusive > 5 % ikke-erythroide/ikke-lymfoide blaster dokumenteret ved knoglemarvsaspirat eller biopsi)

  • Institutionel immunfænotypekarakterisering er påkrævet for tilmelding til undersøgelse

Hjælpe-korrelativ
Patienter gennemgår periodisk opsamling af perifert blod til biomarkøranalyse. Prøver analyseres for GATA1-mutationer ved realtids-PCR, polymorfismer, cytogenetik og K-RAS-mutationer, genekspression, lægemiddelfølsomhedsmønstre og minimal resterende sygdom ved flowcytometri.
