I've had at least 3-4 rounds of BCG since 2017, maybe more. I've never had a clear report. I started with low grade non invasive and graduated to high grade.
On a recent checkup my doctor saw another patch that looked suspicious. He conferred with another oncologist. Keytruda was recently approved for bladder cancer. There is not a lot of data for concurrent BCG and Keytruda, but they could not find a reason not to do it.
I did another 6 weeks of BCG with Keytruda given intravenously every 3 weeks.
After 8 weeks past my last BCG, a cysto showed NOTHING and cytology showed NO CANCER CELLS!!!. I am now on maintenance BCG and will continue with the every three week Keytruda for 2-3 years.
