Hi,
Wow, you are one of the few folks I've met who has been able to go that far with the Lamm protocol...most find it too toxic to complete without lowering the doses or skipping some instillations. Dr. Lamm himself says that lowering the dose doesn't compromise its effectiveness, so maybe that is an answer for you. Otherwise, couldn't it be that you've completed treatment, you're done?
Aside from BCG there are BCG+IFN (interferon); Gemzar instillations (a chemo drug), and many other new drugs being tried in and out of trials.
I would be very tempted to give myself a break from all the treatments if I were in your shoes...
What was your initial diagnosis, and have you ever had any recurrences while on BCG?
All the best,
Wendy
