Term
what are 4 characteristics of a tumor that show it will respond well to chemo
Definition
fast growth
smaller
in growth stage (current proliferation)
areas of metastasis die easier
Term
how can you perdict the size of a tumor
Definition
mass doubling is inversley proportional to growth fraction
tumors >1cm cause symptoms
Term
why do we do multiple rounds of chemo 2
Definition
to prevent resistance

pt may appear in remission because tumor decreased in size but it isn't gone
Term
why do we follow cancer surgery with chemo
Definition
chemo has a hard time penetrating large tumors, if there was tissue left it should be easily penetrated
Term
why do some tumors have necrosis and some dont
Definition
diffusion of blood only goes 150um

some tumors are in steady state with a diffusion distance where rate of death equals rate of new cells

some outgrow their distance from the vessel and undergo necrosis

some make VEGF and produce their own vessels to avoid this problem
