Many of you know that I am fighting metastatic (stage IV) breast cancer. I had a PET/CT scan on Monday which showed a great deal of progression - the chemo I was taking didn't do its job, so it's time to move on to another one. I have a team of oncologists from Dana Farber who are searching through clinical trials to determine which would be the best one for my situation. The kicker is that they want me to wean myself off metformin. That will open up additional trials to me - in many of them, you must be diet-controlled rather than on a medication.
One didn't understand why I was on it as I had a "perfectly normal" a1c. She is extremely knowledgeable about breast cancer but maybe not so wise about diabetes and managing glucose levels to get as close to normal as possible. And in these clinical trials, they seem to indicate that an a1c below 8.0 is diet-controlled enough.
So, I am weaning myself off 2000 mg of metformin. I think I can manage to the mid-6 range without it. Even with metformin, my morning fasting numbers range in the 110-140 range, but then tend to go down for the rest of the day. I have been pretty loose lately but I'll have to tighten up and pay closer attention. It will be interesting to see how I do with this.
Keep in mind that I am over 60 and many doctors are suggesting looser targets for us "seniors." And to be honest, complications from higher than normal blood sugars are the least of my worries. I can do the clinical trials and since they usually last for just several months, I can get back on the metformin if necessary.
One interesting trial uses a platinum chemo (known to be somewhat successful with my particular type of breast cancer) combined with generic Actos. That one interests me because the Actos would control the blood sugar (it's hard for me to let go of the idea of tight control) while, combined with the carboplatin, would hopefully knocking out the nasty cancer. I think there is some risk of congestive heart failure with Actos, but I have no known heart issues so I think I'd probably tolerate it OK.
I have some challenges ahead, for sure!
