Hi, I am not a doctor but I failed BCG treatments and have been given intravesical gemcitabine and now intravesical mitomycin. I believe that BCG has a higher percentage of success but I do believe that gemcitabine is also often successful.
You didn't list your stage and grade. Mine is low grade intermediate risk (I have had many recurrences). At the moment I am on a maintenance schedule of mitomycin. Last 2 cystos were No evidence of disease. I get checked again in November after my 3 weeks of mitomycin.
I'm going on 6 years of various treatments. So far no progression.
Hopefully the chemo will work for you too.
