Role of CDK4/CDK6 inhibitors: Ribociclib, Palbocilcib and Abemacilcib in treatment of metastatic breast cancer / CDK4/CDK6-hämmare: Ribociclib, Palbociclib och Abemaciclib för behandling av metastaserande bröstcancer

Ghobadpour, Nazanin January 2021 (has links)
Breast cancer is the most common cancer among women in Sweden and globally. Socio-demographic, genetic and productive factors together with some endogenous and exogenous hormones and lifestyle are some of the risk factors that can cause this type of cancer. There is no cure for metastatic breast cancer but the treatment goal is to control the disease and prolong the survival. Treatment options in metastatic breast cancer are exactly like the ones in primary breast cancer. Targeted cancer therapy is a treatment that targets either one or some specific characters of the cancer. Serine-threonine kinases called CDK4/6 inhibitors like Ibrance with chemical name palbociclib, Kisqali with chemical name ribociclib and Verzenios with chemical name abemaciclib are used for target therapy against metastatic breast cancer. CDK4/6 inhibitors in combination with aromatase inhibitors, estrogen receptor down regulators or selective receptor modulators are also used to address the treatment resistant metastatic breast cancers. The aim of this thesis is to investigate the role and the effect of CDK4/6 inhibitors in the treatment of metastatic breast cancer. Six randomized controlled trial studies were selected from the PubMed data base. Results from the trial analysis showed equal effects and relative same adverse event profiles between those three mentioned CDK4/6 inhibitors. The primary endpoint, progression free survival and secondary endpoints including overall survival, clinical benefit rate, overall response rate and safety were investigated in these studies. The duration of progression free survival (PFS) and overall response rate (ORR) was longer and improved in most studies however improvement in overall survival (OS) was not achieved. More research studies are needed to determine optimal treatment for patients with metastatic breast cancer who are medicated by CDK4/6 inhibitors. / Bröstcancer är den vanligaste cancerformen bland kvinnor i Sverige och globalt. Sociodemografiska, genetiska och reproduktiva faktorer samt vissa endogena och exogena hormoner och livsstil är några riskfaktorer som kan orsaka denna typ av cancer. Metastatisk bröstcancer innebär att cancer har spridit sig bland andra organ i kroppen bland annat ben, hjärna, lever och lungor. Det finns inget botemedel mot metastatisk bröstcancer men målet är att kontrollera sjukdomen och förlänga överlevnaden och behandlingsalternativ för detta är exakt som den i den primära bröstcancern. Målspecifik cancerterapi är en behandling som riktar sig mot någon specifik karaktär hos cancercellerna. En klass av läkemedel består av en stor familj av serintreoninkinaser som kallas CDK4/6-hämmare: Ibrance (palbocilcib), Kisqali (ribocilcib) och Verzenios (abemaciclib) används mot metastaserad bröstcancer. Syftet med det här examensarbetet var att undersöka rollen samt effekten av CDK4/6 hämmare vid behandling av metastatisk bröstcancer. Sex randomiserade kliniska studier erhölls från artikelsökningar i databasen PubMed. Resultat från artikelanalyser visade likvärdiga effekter samt relativt samma biverkningsprofil mellan de tre ovannämnda CDK4/6 inhibitorerna. Den primära utfallsvariabeln var progressionsfri överlevnad och de sekundära utfallsvariablerna inkluderade total överlevnad, klinisk nytta, den totala svarsfrekvensen och säkerhet undersöktes i dessa studier. Varaktigheten av progressionsfri överlevnad (PFS) samt den totala svarsfrekvensen (ORR) var längre och förbättrades i nästan alla studier medan den totala överlevnaden (OS) kunde inte fastställas då inte tillräckligt med data kunde samlas in. Ytterligare undersökningar behövs för att förstå den fulla mekanismen bakom resistensutveckling samt utöka strategier för att minska negativa biverkningar av CDK4/6 hämmare vid behandling av patienter vid metastatisk bröstcancer.
