What feature of the cell cycle accounts for some selective toxicity for antineoplastic agents? (Select all)
A. Drugs that target the G1 phase will not affect our human cells
B. Our normal human cells spend most of their time in G0 phase (resting phase)
C. Cancer cells spend most of their time in the G0 phase (resting phase)
D. Chemotherapeutic medications have a more pronounced effect on cells (cancer or human) when they are in any phase of the cell cycle and are not in the G0 phase.
E. Cancer cells do not enter the G0 phase and are actively replicating
B. Our normal human cells spend most of their time in G0 phase (resting phase)
D. Chemotherapeutic medications have a more pronounced effect on cells (cancer or human) when they are in any phase of the cell cycle and are not in the G0 phase.
E. Cancer cells do not enter the G0 phase and are actively replicating
What is the cell-kill hypothesis?
A. Relates to the magnitued of normal cells killed by chemotherapy with each round of anticancer drugs
B. Relates to the magnitude of tumor and cancer cells killed by chemotherapy with each round of anticancer drugs
C. Relates to the magnitude of tumor and cancer cells that have regenerated despite chemotherapy and anticancer drug adnimistration
D. None of the above
B. Relates to the magnitude of tumor and cancer cells killed by chemotherapy with each round of anticancer drugs
Why are several rounds of chemotherapy given with rest periods? (Select All)
A. Several rounds of chemotherapy are needed because remaining cancer cells can still replicate
B. Several rounds are given because decreasing as many human cells as possible will decrease the chances of the cancer spreading to other healthier cells.
C. The rest period is given to allow normal cells to regenerate from the chemotherapy
D. The rest period is given to allow adequate time for cancer cells to enter the G0 phase and remain dormant.
A. Several rounds of chemotherapy are needed because remaining cancer cells can still replicate
C. The rest period is given to allow normal cells to regenerate from the chemotherapy
Why are chemotherapy drugs given in combination? (Select All)
A. Multiple drugs cover many mechanisms of action and act at different areas of the cell cycle or indipendent of cell cycle.
B. Decreases the likelihood of therapy failure
C. Allows for multiple mechanisms of resistance to develop
D. Allows for the selection of multiple medications in order to treat the condition and manage the drug selection based on side effect profile
