Effect of Herceptin cycle on Scan results
Hi All,
Can the scan results be effected by on which day during the Herceptin cycle we get the scan?
I got my PET/CT scan a week after I got my 3 week dose of Herceptin. My san results showed partial decrease of the disease eventhough the tumor markers(Her2 serum,CEA and CA27.29) showed progression while I was on Navelbine. I am wondering this may be due to getting the scan too close to the Herceptin infusion.
Also the new report shows a nodular contour on the wall of uterus, this may be a benign cyst or something else, I need to get an ultra sound.
Can these cysts alter the tumor markers? Usually Her2 serum is a very reliable indicator for me.
Thanks,
Julie
