My husband was on Tarceva 150mg for 26 days. Had to take 4 days off due to rash and then began again at 75 mg.
On Tarveva day 63, March24, a scan was done . Result- several small suspected cancerous nodules seen on January scan (all less than cm) are showing small progression. A 2.5 cm nodule shows no real change.
Oncologist wanted to stop further treatment. We requested that we stay the course for another 4-6 weeks and he agreed.
My questions are as follows:
is a rash a predictor that Tarceva is working or can none responders develop it as well?
is 63 days enough time to determine that Tarceva is or is not working given inconsistency of dosing?
Note:We were used to 3 month scans previously.
would going up to 150 mg for another month to 6 weeks and staying on it consistently be a better predictor if/how Tarceva is working.
Thanking you in advance..
