My husband has been on Afatinib since October last year, The first CT-scan after 6 weeks was very good- majority of the cancer nodules showed significant shrinkage. Since then, he was doing well, and the doctor has been using X-ray for monitoring the progress. Recently, he felt the pain slowly coming back, and so is the shortness of breath. But last week's X-ray result shows "no significant change". I am worried and wondering whether I should talk to doctor to do a CT-scan on him or continue using X-ray to monitor his progress in the next appointment?
How big the difference is between a CT-scan result and an X-ray result? is it good enough using X-ray for monitoring significant progress? The rational here is: if he is slowly progressing, he should stay on Afatinib. Only if he has major progress, we should stop the medicine.
