General Pharm (Chemo/Alkylating&Hormones/Anti-Metabolites) Flashcards
Gompertzian Growth
tumor takes constant amount of time to double its size
Goldie-Coldman Hypothesis
best strategy prevention of tumor resistance is to initiate treatment early and use a combination of drugs with non-overlapping toxicities
Partial response to anti-cancer
reduction of at least 50% in the diameter of all measurable lesions
Stable disease
range from decrease of < 50% to increase of < 25% in diameter product of tumor
Progressive disease
increase of more than 25% in diameter product of any lesion
