Oncology II Flashcards
Whats Dubois and Dubois formula used for? What is the formula?
body surface area
BSA (m^2) = 0.007184 x Height (cm)^0.725 x Weight (kg)^0.425
Whats Mosteller formula used for? What is the formula?
body surface area
BSA = | (Ht -cm x Wt -kg)/ 3600
List phases of cell cycle
M - mitosis - cell divides into 2 daughters
Go - Resting phase post mitosis - no cell division occurs
G1 - Post-mitotic phase - where enzymes & proteins are synthesized
S - DNA synthesis and duplication occurs
G2 - Pre-mitotic phase - RNA and Topoisomerase I and II are produced to prepare for cell division
M phase drugs
Vinca alkaloids
Taxanes
G0 phase drugs
None! No drugs work here
G1 phase drugs
Post-mitotic phase - where enzymes and proteins are synthesized (Cell growth and preparation for DNA replication)
None!
S phase drugs
Topoisomerase I inhibitors
Antimetabolites
- Pyrimidine-analog antimetabolites
- Folate antimetabolites
What’s G2-phase of the cell cycle?
Pre-mitotic phase - RNA and Topoisomerase I and II are produced to prepared for cell division
G2 phase drugs
Topoisomerase II inhibitors
List non-cell cycle specific agents
Alkylating agents
Anthracyclines
Platinum agents
MOA of Alkylators?
Non-cell cycle specific: Cross-links DNA, preventing cell replication
List the main Alkylators?
Cyclophosphamide (Cytoxan)
Ifofsamide (Ifex)
Brand name of Cyclophosphamide? Alkylator (non-cell cycle specific)
Cytoxan
Brand name of Ifosfamide? Alkylator (non-cell cycle specific)
Ifex
Whats concern with High-dose Cyclophosphamide (Cytoxan) and all doses of Ifosfamide (Ifex)? What’s done to mitigate concern?
Hemorrhagic cystitis
Give MESNA (Mesnex) + High-dose Cyclophosphamide (Cytoxan)
MESNA (Mesnex) + ALL doses of Ifosfamide (Ifex)
Which Alkylators is also an MAO-I?
