 have you had your second scan yet to see whether they were just psuedoprogressors? very common to progress then shrink on the second or later scans. i'm watching this combo and it looks to be a major jump in the standard of care for mss-crc. good luck! keeping my fingers crossed.
I always get the quiet parts and the out-loud parts mixed up.
