After 2 Keytruda infusions added to my Alimta treatments, the CEA has risen, but after the 2nd Keytruda it has risen half as much as after the first. So although it’s not going down it has slowed so we’re hoping the next blood test in 3 weeks that will actually fall or rise slower. If not, who knows what’s next. Crizotinib is being discussed as next possibility. Getting another PET scan before that. I’m tolerating this current cocktail fairly well, a bit more tired for the week following infusions. But still able to exercise and live normally the other 2 weeks between treatments.
