I ran across this article that talks about using lower dosages of chemo drugs. It mentions one of my drugs, trastuzumab (Herceptin). I'm supposed to be on it for a year.
There was a large U.K. study that showed that six months on the drug was just as effective as 12 months. But there was also a French study that showed that six months was not as effective.
One serious side effect of Herceptin is heart problems such as reduced heart function and congestive heart failure. That's why I had to get an echocardiogram before starting chemo. I'll have to ask my oncologist for her opinion about the studies. It would be nice not to have to be on Herceptin and Perjeta for a year.
