Rapport från ASCO- Och kliniken Målstyrd behandling vid lungcancer Karl-Gustaf Kölbeck, öl, sektionschef Lung Allergikliniken Karolinska Universitetssjukhuset
Vad är målstyrd behandling vid cancer? drugs or other substances that interfere with specific molecules involved in cancer cell growth and survival. Traditional chemotherapy drugs, by contrast, act against all actively dividing cells NCI, 2014 2

Management and Future Directions in NSCLC with Known Activating Mutations Presented By Daniel Costa at 2014 ASCO Annual Meeting
EGFR-muterad lungcancer: Kliniska karakteristika Oberoende av rökstatus (?) Drabbar alla åldrar (>30) Prognostisk betydelse: Fördubblad medianöverlevnad jämfört annan lungcancer Prediktiv betydelse: Svarar bra på både målstyrd behandling och traditionell cytostatikabehandling Titta noggrant på svar från lab: Vilken typ/typer av mutationer? 6

EGFR TKIs and EGFR mutated NSCLC:<br />major mechanisms of resistance to EGFR TKIs (2) Presented By Daniel Costa at 2014 ASCO Annual Meeting
Vad göra vid progress? (Evidensbaserade råd finns ej) Asymtomatisk (långsam) progress: fortsätt med insatt TKI. Planera gärna in re-biopsi! Progress i en metastas: Riktad behandling (ex.srt hjärna, binjure), fortsätt insatt TKI Symtomgivande progress: Traditionell cytostatikabehandling. Om förutsättningar finns först re-biopsi: #T790M påvisad: 1:a-2:a generationens TKI dålig effekt. Studie. #Met-amplifiering: Krizotinib? #Transformering till småcellig lungcancer: Kemo Costa, ASCO 2014 15

Tumor Shrinkage Seen in Intermediate <br />and High MET Cohorts Presented By D. Camidge at 2014 ASCO Annual Meeting
Obesvarade frågor om EGFR-muterad lungcancer (Costa, ASCO 2014) Vilken roll har EGFR-TKI:s vid stadium l-lll? Vilken TKI (gefitinib/erlotinib/afatinib) skall användas för EGFR L858R repektive exon 19 deletion, samt för mindre vanliga mutationer? Vilken plats har fortsatt terapi med initial TKI vid sjukdomsprogression? Vilken tredje generationens TKI skall användas vid T790M mutation? Hur mycket dokumentation/studier behövs innan registrering? Vilka behandlingskombinationer kan försena eller förhindra behandlingsresistens vid EGFR-positiv lungcancer?
