APHON:12 Principles of Cancer Chemotherapy ppt 12

QuestionAnswer
Two drugs origionally designed as antibiotic's that are antimetabolites (anti cancer drugs)? Actinomycin (second antibiotic ever developed) & Daunorubicin
Class of dDrugs developed specifically for cancer treatment? ANTIMETABOLITES: interfere with metabolic pathways or disrupt DNA synthesis
NCI formed in what decade? 1930's
Clinical trials on 1st chemo (nitrogen mustard) completed in what decade? 1940's
Def: Pharmacokinetics Pharmacokinetics:drug absorption, metabolism, and excretion. How the body processes drugs.
Def: Pharmocodynamics CONCENTRATION of Rx in vivo BIOPHYSICAL MECHANISM. Principles of pharmacokinetics and pharmocodynamics are used to develop drug dose and schedules, which will maximize tumor cell kill and minimize toxicity.
Def: Multimodal Therapy Use of several forms of therapy in the course of treatment. Chemotherapy, surgery, hematopoietic cell transplant (HCT),radiation (XRT).
Def Adjuvant chemotherapy use of chemotherapy following another form of therapy, such as surgery, to treat residual disease or undetectable metastasis.
Def: Neoadjuvant chemotheapy Neoadjuvant chemotherapy is used preoperatively to decrease tumor bulk in order to make it easier to remove the tumor surgically.
Def Sanctuary site places within the body that tumor cells can hide. Sites not easily reached by systemic chemotherapy. Ex: CNS in leukemia.
How does chemo work "indiscriminately kills rapidly dividing cells". Malignant & normal cells (BM, oral mucosa, GI tract, hair folicles)
Goals of chemo cure dx, control dx or palliation
Cell cycle: what is G 0 (gap 0)? RESTING PHASE: cells not dividing. length extremely variable. (not "in cell cycle")
Cell cycle: what is G 1 (gap 1)? Second phase. POST-MITOTIC PHASE; cells enter cell cycle. Production of enzymes needed for DNA synthesis, proteins and RNA synthesis occurs. The length 18 hours.
Cell cycle: what is S (synthesis) phaze? DNA DUPLICATION PHASE in preparation for cellular division. Length 20 hours.
Cell cycle: what is G2 (gap 2)? PREMITOTIC PHASE. Both protein and RNA synthesis occur and the precursors to the mitotic spindle apparatus are produced. This phase is very short.
Cell cycle: what is M (Mitosis) phaze? CELL DEVISION. Four phases: Prophase: nuclear membrane breaks down chromosomes clump. Metaphase chromosomes align in middle of the cell. Anaphase chromosomes separate move to centriole. Telophase cell division two identical “daughter” cells. one hour.
Cell cycle: what is Prophase? phase 1 of Mitosis: . During prophase the nuclear membrane breaks down and chromosomes clump
Cell cycle: what is metaphase? Phase 2 of Mitosis: In metaphase the chromosomes align in the middle of the cell.
Cell cycle: what is Anaphase? Phase 3 of Mitosis: During anaphase the chromosomes separate and move to the centriole
Cell cycle: what is Telophase? Phase 4 of mitosis:Telophase results in actual cell division and the production of two identical “daughter” cells. This process takes approximately one hour.
Cell cycle: what is cell cycle time? Significance? time for cell to move from one mitotic episode to another. Length dependent on cell type & time in GO. Short cycle= higher kill with cycle specific agents. Continuous infusion of these Rx => higher cell kill in tumors with short cell cycle times.
What is the Cell Kill Hypothesis Sates that a percent of CA cells are killed with each cycle of chemo. ultimately only a few cells remain and the immune system destroys them. Rational for multiple cycles of chemo. Peds Ca high growth fraction so are suseptible to tx.
Def: Growth Fraction % of cells actively dividing at a given point in time - higher growth fraction ->higher cell kill with cycle specific agents - tumors with greater fraction of cells in G0 will be more sensitive to cell cycle nonspecific agents
Def: Tumor burden # of cells in tumor - ca with small tumor burden more responsive to antienoplastic tx. - Higher cell burden -> Rx resistance
Def: Gompertzian function Tumor burden growth is initially exponential but levels off as blood, O2 & nutrient supply is limits. Center of tumor becomes necrotic.
6 characteristics of malignant cells 1)Mutated DNA alters function 2) Parasitic to host 3)Uncontrolled reproduction 4) Invade surrounding tissues and metastasize 5)immortal (no apoptosis) 6)cell birth> cell death
6 mechanisms of Rx resistance -decreased drug uptake by cell -increased excretion out of cell -detoxification of drug by cell -increased DNA repair -alterations in structure of Rx receptor sites -decreased apoptosis
3 reasons for multidrug resistance gene (MDR) - intrinsic (MDR present in tumor prior to tx) - acuired (resullt from genetic mutation following chemo) -Results from P-glycoprotein (rapidly eliminates Rx from cell eg anthracycline, vinca alkaloids)
3 reasons for multidrug resistance gene (MDR) - intrinsic (MDR present in tumor prior to tx) - acuired (resullt from genetic mutation following chemo) -Results from P-glycoprotein (rapidly eliminates Rx from cell eg anthracycline, vinca alkaloids)
4 principles of combination chemotherapy - 2+ Rx have greater response (act in diff phases of cycle, vary toxicities) - each Rx has independent action - synergistic effects -decreased Rx resistance
4 characterists of cell cycle specific chemo -greatest effect on actively deviding cells -not active in G0 -best as in divided doses or as continuous infusion -cytotoxic effects occur when cell repair or devision attempted
4 characteristics of cell cycle non-specific chemo -work in any phase -active in G0 - best as bolus -cytotoxic effects when cell division attempted

What does zinecard do? protects heart from doxorubicin
What does mesna do? To prevent haemorrhagic cystitis and haematuria when a patient receives ifosfamide or cyclophosphamide for cancer chemotherapy which converts tp urotoxic metabolites such as acrolein. Increases excretion & binds to toxin.
What does amifostine do? reduce neutropenia-related fever and infection induced by DNA-binding chemo. alkylating agents (e.g. cyclophosphamide) and platinum-containing agents (e.g. cisplatin). It is also used to decrease the cumulative nephrotoxicity with platinum-containing rx.
