Medical Oncology - CRC and lung cancer Flashcards
Drugs for colorectal cancer (CRC)
5-Floruracil
Capecitabine
Irinotecan
Cetuximab
Panitumumab
Pembrolizumab
Nivolumab
CRC- 5- fluorouracil utility/mutations
DPD *2A - splicing mutation
DPD is needed for pyrimidine catabolism
CRC - 5 fluorouracil IM and PM
IM: reduce dose by 50%
PM: don’t use
CRC - capecitabine utility/mutation
DPD
DPD needed for pyrimidine catabolims
CRC - irinotecan utility/mutation
UGT1A16/28 allele
causes reduced enzyme activity and toxicity
CRC - cetuximab utility/ mutations
KRAS/NRAS/EGFR
- focus on exons 2, 3, 4
mutations in KRAS = unchecked growth
CRC - panitumumab utility and mutaion
KRAS/NRAS/EGFR
- exon 2, 3, 4
mutauion in KRAS = unchcked growth
CRC- Pembrolizumab utility/mutation
MS1/MLH1/MSH2/MSH6/PMS2/CD274
when MSI-H or dMMR present
express PD-L1 (CD274) expression
CRC- nivolumab utility /mutation
MS1/MLH1/MSH2/MSH6/PMS2/CD274
when MSI-H and dMMR present
expresses PD-L1 (CD274) expression

CRC what is the only pro-drug?
irinotecan
Lung Cancer - what are the KRAS mutation drugs?
Sotorasib and Adagraside
Lung Cancer - Sotorasib utility/mutation
KRAS mutation in G12C
Lung Cancer - Adagrasib utility/mutation
KRAS - G12c mutation
Lung Cancer - what are the EGFR drugs?
Geftitinib
Erlotinib
Afatinib
Docomitinib
Osimertinib
Mobocertinib
Lung Cancer - gefitinib mutation/utility
EGFR
- exon 19 deletion or exon 21 substituion
- not effective against exon 20 mutation
Lung Cancer - Erlotinib mutation/utility
EGFR
- exon 19 deletion, exon 21 substitution
not effective against exon 20 mutation
Lung Cancer - Afatinib mutation/utility
EGFR
- exon 19 deletion, exon 21 substitution
not effective against exon 20 mutation
Lung Cancer - dacomitinib mutation/utility
EGFR
- exon 19 deletion, exon 21 substitution
not effective against exon 20 mutation
