How do you measure if tarceva (erlotinib) is working on the lung cancer? how do you measure the efficacy?
In brief:
Repeat CT scanning
Repeat ct scaning after 2-3 months of
tarceva (
erlotinib) use is done to measure the size of
lung cancer lesions and to see if they are shrinking.
Patients who get a severe
skin rash with tarceva (erlotinib) are often likely to benefit more from tarceva (erlotinib) therapy.

In brief:
How to measure
At least two ways-
- clinically- there is a correlation between the presence of acneiform
rash -usually on the head/face-after you take
tarceva (
erlotinib)- with the efficacy of tarceva (erlotinib).
The rash will start to appear within the first 2-3 weeks after you start tarceva (erlotinib).
~
imaging finding.
Ct scan or pet/ct after a few months on tarceva (erlotinib)- will tell you whether the
cancer responds to tarceva (erlotinib).
