A 48-year-old woman has a routine physical examination. A 4 cm diameter non-tender mass is palpated in her right breast. The mass appears fixed to the chest wall. Another 2 cm non-tender mass is palpable in the left axillary node. A chest radiograph reveals multiple 0.5 to 2 cm nodules in both lungs. Which of the following TNM classifications best indicates the stage of her disease? A. T1 N1 M0 B. T1 N0 M1 C. T2 N1 M0 D. T3 N0 M0 E. T4 N1 M1
E, metastasis present because it spread to lungs
27
3 things cancer is characterized by
uncontrolled cell growth tissue invasion metastasis
28
v-Src is a/an _____
oncogene
29
RB1 is a __________ _________
tumor suppressor
30
Most tumor suppressors need to be a __________ deletion/mutation
homozygous
31
Which type of tumor suppressor mutations can be inherited?
heterozygous
32
T or F a "loss of heterozygosity" leads to a higher predisposition to cancer
True
33
Most cancers are relatively _____geneous and have a variety of gene mutations
hetero
34
T or F: BRCA1 and BRCA2 are oncogenes
False dumbass, theyre tumor suppressors
35
The BRCA1 and 2 genes encode for proteins involved in ______
DNA repair
36
BRCA mutations in breast cancer increase susceptibility to ______ inhibitors
PARP
37
Olaparib: Class: ________ MOA: Primarily for cancers with ________ mutations:
-PARP inhibitor - "trapping" PARP to DNA so it can't go fix strand breaks - BRCA1/2
38
cell is quiescent or accumulating "building blocks" required for division A. G0/G1 B. S C. G2 D. M
A. G0/G1
39

C. g2
41
Mitosis A. G0/G1 B. S C. G2 D. M
D. M (no shit)
42
______ and ______ are master regulators of cell cycle initiation
Cyclin D, CDK4/6
43
what is a mitogen?
something that promotes growth
44
Palbociclib class / MOA
CDK4/6 inhibitor
45
Which of the following is potentially true of a tumor suppressor gene? A. Allows unrestricted cell growth and proliferation. B. Promotes different phases of the cell cycle. C. Produces proteins that block the activity of cyclins. D. Is often overexpressed in cancer
C
46
T or F: loss of checkpoint control results in decreased cell death with chemotherapy
false, increased
47
Which cell cycle checkpoint ensures integrity of the genome?
G1 checkpoint
48
in what phase are drugs that do not require cycling cells effective in? (this is worded terribly im sorry)
G0
49
A chemotherapy that interferes with DNA synthesis is A. S-phase specific B. G1-phase specific C. cell cycle non-specific D. M-phase specific
A
50
Which phase of the cell cycle do you think is targeted by Palbociclib (the CDK4/6 inhibitor)? A. G1 B. S C. G2 D. M
A
51
T or F: Single doses of chemotherapy drugs will select for cells resistant to drug instead of killing all tumor cells
True
52
Things listed under "major dose-limiting toxicities"
Hematopoietic- WBC, infections, platelets, hemostasis, RBC (all go together when you think about it) and GI upset, N/V, loss of appetite
53
2 advantages of combination chemotherapy
- no additive toxicity for drugs with non-overlapping* toxicities - increased cell killing
54
Chemoresistance: what are the 2 pumps that increase transport of drugs out of the cell through efflux pumps?
P-glycoprotein (PgP Multi-drug resistance associated protein (MRP)
55
Chemoresistance: what are two ways cancer cells reduce drug transport into the cell?
loss of drug importer decreased membrane permeability
56
Chemoresistance: T or F: Cancer cells can decrease the activation of prodrugs
True
57
Chemoresistance: Cancer cells may _________ ________ or processes that detoxify the drug, making it less harmful or ineffective.
upregulate enzymes
58
T or F: Cancer cells that metastasize to the brain can avoid certain chemo drugs
True, some drugs don't cross the BBB
59
What happens due to cancer cells making a physiological change in cell state such as EMT (epithelial mesenchymal transition)?
Slows cell cyle, increases drug efflux pumps and increases anti-apoptotic proteins
