Typical means used to evaluate the effects of a drug in animal models
of cancer include which of the following? (there may be more than one)
a. measurement of % inhibition of tumor growth
b. measurement of time of delay for the tumore to grow to a certain
size
c. measurement of the weight changes of the lungs in experimental lung
metastatic tumor models
d. measurement of time to death

Hi -

These are all measured endpoints in various studies.

Answers a,b are similar methods for estimating the effect upon growth
- answer b is an example of a threshold type measurement.  A company
which offers services such as these:
