Dette prosjektet fokuserer på verdien av preoperativ avansert funksjonell bildebehandling for å gi funksjonelle og morfologiske svulstkarakteristikker som er relevante for behandling og prognose i endometriekreft. En unik pasientserie som prospektivt blir utsatt for preoperativ funksjonell bildebehandling ved magnetisk resonans imaging (MRI) og positronutslipp tomografi (PET) - computertomografi (CT) i løpet av 2009-2016, vil bli studert. Parallelt vil preklinisk PET-CT utført sekvensielt av en ortotopisk livmorkreft-musemodell bli undersøkt i forløpet av tumorprogresjon og metastase. Funksjonelle bildefunn i pasientene og dyremodellen vil bli utforsket i forhold til kirurgiske staging-resultater, utfall og histologiske og molekylære markører. Prosjektet tar sikte på å 1) Utforske funksjonelle bildefunn, dvs. potensielle bildebehandlingsbiomarkører som predikerer avansert tumorstadium, metastaser og redusert overlevelse i livmorhalskreft. 2) Validere og sammenligne disse billeddannende biomarkørene med etablerte histomorfologiske og molekylære biomarkører i livmorkreft og til slutt; 3) Implementere disse billeddannende biomarkørene i preoperativ risikostratifisering, for å muliggjøre bedre skreddersydd og individualisert behandling av livmorhalskreft.

Dette prosjektet er i samarbeid med Prof Ingfrid S Haldorsen. 

Endometriet er svært hormonfølsomt og uttrykker både østrogen og progesteronreseptorer. I endometriet hemmer progesteron den vekstfremmende effekten av østrogen, og induserer differensiering. Pasienter med høyt plasmaøstrogen og / eller lavt progesteron har økt risiko for endometriecancer, da østrogenets vekstfremmende effekt ikke balanseres av progesterondrevet differensiering. Flere studier har vist at ER og PR-status er viktige prognostiske biomarkører, og predikerer også respons på antihormonell behandling i endometriekreft. Vi har nylig identifisert at også AR har prognostisk innvirkning, og kan potensielt være et attraktivt terapeutisk mål. I dette prosjektet undersøker vi potensialet for faktorer relatert til hormonsignalering, som biomarkører i endometriekreft, og relaterer ekspresjon av disse markørene med klinisk fenotype og endringer i genuttrykk. Vi undersøker også endringer i uttrykk for disse markørene fra primære til metastatiske lesjoner. Det er ingen godkjente målrettede behandlinger, utover hormonell behandling for pasienter med endometriekreft. Derfor er karakterisering av metastasiske lesjoner, identifisering av nye biomarkører og potensielle terapeutiske mål både i primære og metastatiske lesjoner viktig for å forbedre behandlingen for disse pasientene.

Behandling av metastasert kreft er en stor utfordring i kreftbehandling. I denne studien fokuserer vi på endometriekreft, den vanligste gynekologiske krefttypen i Norge og den vestlige delen av verden. Vi har som mål å beskrive genetiske endringer, og å sammenligne den primære svulsten med metastaser hos kvinner med sykdomspredning. Dette ved hjelp av neste generasjons sekvenseringsverktøy (exome-sekvensering). En oppsiktsvekkende heterogenitet ble observert mellom biopsier av parede primære svulster og metastaser fra samme pasient, hvor bare halvparten av mutasjonene er felles i to biopsier -i gjennomsnitt. Når man definerer paret av mutasjoner i hver biopsi, kan et slektstre av den evolusjonære historien til endometriekreft avsløre informasjon om hvordan metastaser utvikler seg. Den nåværende modellen antyder at metastaserende endometriekreft stammer fra én enkelt grunnleggende subpopulasjon av primærtumoren. Denne studien utføres i nært samarbeid med ekspertforskere ved Broad Institute, Boston, USA.

De overordnede målene med denne studien er å identifisere molekylære endringer som kan vise veien til nye behandlingsstrategier i livmorhalskreft, samt å avsløre potensielle biaser introdusert i prosessen med å avdekke molekylære endringer ved molekylærprofileringsteknikker som krever høyt tumorcelleinnhold.

Prosjektet har som mål å identifisere kandidatproteinmarkører (for eksempel HER2, p53) og å evaluere deres potensial som prognostiske og / eller prediktive markører som styrer behandling av livmorkreft. Ekspresjonen av kandidatmarkører er knyttet til kliniske trekk og transkripsjonsprofiler både i endometrie- og livmorkreft. I tillegg sammenlignes proteinekspresjonssmønstre i primære og samsvarende metastaserende endometriekreft-lesjoner.

Vi har etablert musemodeller for endometriekreft, hvor kreftceller er implantert i livmoren hos kvinnelige mus og som dermed vil danne tumor. I tillegg til bruk av kommersielt tilgjengelige kreftcellelinjer, implanterer vi også celler fra pasientenes primære svulster for å lage pasientledede xenografter (PDX), som antas å være mer representative for den kliniske fremstillingen enn cellelinjebaserte modeller. Musemodeller er verdifulle verktøy i preklinisk forskning, og kan brukes til å studere svulsters egenskaper og terapeutiske responser. Vi bruker vår endometriekreft-musemodell for å undersøke mulige forbindelser mellom ekspresjon av spesifikke proteiner i tumorceller og respons på utvalgte kjemoterapeutiske legemidler. Tumorvekst hos mus kan overvåkes over tid med forskjellige små dyrebildningsmodaliteter, og vi bruker for tiden PET-CT og optiske avbildningsteknikker for å visualisere tumorutvikling. Vi arbeider også med å etablere nye bildebehandlings-protokoller som kan brukes i PDX-modeller.
