Antineoplastic Flashcards
(157 cards)
The branch of medicine concerned with the study of malignancy-development, dx, tx, and prevention is defined as:
Oncology
Pertaining to a substance, procedure, or measure that prevents proliferation of cells is defined as:
antineoplastic
The pharmaceutical agents used to destroy CA cells are defined as:
antineoplastics or cytoxic drugs
What phase of the cell cycle is not as sensitive to antineoplastic Tx as the other phases of the cell:
Go
What type of cells arise from a single abnormal cell that multiplies and grows:
CA cells
What happens as abnormal cells continue to divide:
They lose some of their original characteristics
What are the characteristics of CA cells:
anaplasia; autonomy; metastasis; angiogenesis
The loss of cellular differentiation and organization is defined as what type of CA characteristic:
anaplasia
To grow in an uninhibited way/manner is defined as what type of CA characteristic:
autonomy
The ability to travel to other sites of the body is defined as what type of CA characteristic:
metastasis
The ability to grow new bld vessels to feed a tumor is defined as what type of CA characteristic:
angiogenesis
What are the specific protocols used before giving chemotherapy to pts:
type/extent of malignancy; type of chemo given; side effects; amount of time normal cells need to recover=giving the chemo in cycles
What are the major factors that affect the CA cells response to chemotherapy:
Growth fraction and doubling time
The percent of actively dividing cells is defined as:
growth fraction
The time it take the cell to double in size is defined as:
Doubling time/growth rate
Anticancer drugs are most effective on CA cells d/t what major factor:
Cells with high growth fraction
Antineoplastic/Anticancer drugs treat malignancies by directly killing tumor cells how:
Damaging the DNA; inhibiting DNA synthesis from replication; stoping mitosis
Antineoplastic drugs destroy CA cells by inhibiting cell division but also affect normal cells. What type of normal cells do they affect the most:
Rapidly multiplying cells or cells that replaces themselves quickly; thus, causing side effects
This type of chemotherapy is used to relieve S/S associated with advanced CA (pain, breathing…) and improve quality of life is defined as:
palliative chemotherapy
This category of antineoplastic drugs exert their influence during a specific phase of the cell cycle; are the most effective against rapidly growing CA cells is defined as and what are the examples:
CCS (cell-cycle specific or cell-cycle dependent); antimetabolites and mitotic inhibitors
This category of antineoplastic drugs exert their influence during any phase of the cell cycle, especially the Go phase is defined as and what are the examples:
CCNS (Cell-cycle nonspecific or cell- cycle independent); alkylating; anti-tumor antibiotics; hormones
The combined use of CCS and CCNS drugs maximize cell death is defined as:
synergistic effect
The synergistic effect of the combination of CCS and CCNS is:
Kills cells in all phases of the cell cycle, especially the cells that have a high fraction rate; decreases drug resistance and increases destruction of CA cells
What are the causes of MDRL:
Cell mutation; natural resistance; gene amplification; repair DNA damage
