Leukopenia- dose limiting. Also infection, bleeding

26
Q

What is the taxane?

A

Paclitaxel

27
Q

MOA of paclitaxel?

A

Bind beta tubulin to prevent microtubule disassembly (opposite of vinca alkaloids)

28
Q

ADE of paclitaxel?

A

Peripheral neuropathy, extravasation

29
Q

What is the anthracycline?

A

Doxorubicin

30
Q

Doxorubicin’s MOA?

A

Dexroxazone

33
Q

VEGF blocker?

A

Bevaciuzmab

34
Q

MOA of bevacizumab?

A

Antibody that binds VEGF –> prevents angiogenesis for tumor growth

35
Q

ADE of bevacizumab?

A

Hemorrhage (esp with squamous NSCLC)

36
Q

TKI’s?

A

Erlotinib, Crizotinib

37
Q

MOA erlotinib?

A

EGFR inhibitor (and HER-1)

38
Q

ADE of erlotinib?

39
Q

MOA of crizotinib?

A

EML4-ALK inhibitor

40
Q

ADE of crizotinib?

A

GI, rash, edema

41
Q

How do you treat NSCLC?

A

First surgery then chemo- Cisplatin and Paclitaxel.. and maybe Erlotinib and maybe Bevacizumab

42
Q

How do you treat adenocarcinoma?

A

First surgery then chemo. Genetic testing is very important. Use Bevacizumab, Crizotinib, Erlotinib

43
Q

How to treat SCLC?

A

No surgery. Just chemo and radiation. Use Etoposide +cysplatin or carboplatin

44
Q

Is KRAS more common in smokers or non-smokers?

A

Smokers
