Enhertu cycle 9 started

David got his 9th dose of Enhertu chemo today (the 4th dose since he restarted chemo in June). Unfortunately, his CEA did not go down much (it was 19 three weeks ago and 18.9 this time).

So, Dr. Brooks advocated increasing the strength of the chemo dose today, and David agreed. That will probably mean stronger side effects, especially since the side effects already became a bit stronger after the last dose. Dr. Brooks said cumulative doses do tend to increase side effects, so he and David will monitor what happens after today’s dose before deciding what to do for the next scheduled dose on Sept. 8.
