Hi Janice, it's standard protocol to do a second TURBT when the cancer is high-grade and the original biopsy/sample does not include muscle tissue. They need the muscle tissue to accurately Stage the cancer (ta, t1, t2, t3) and determine if the tumor was superficial or invasive. The treatment paths will depend on the grade of the cancer and whether it is noninvasive or invasive. At this point, you only know the grade. I do suggest that once you have the second TURBT, have your slides sent out for a second opinion to confirm the pathology/diagnosis. (I had mine sent to Johns Hopkins.)
BCG treatments are normally used for noninvasive, high-grade bladder cancer. There is an induction phase of 1x a week for 6 weeks. After the 6 induction treatments, they do a cystoscope and take a peek inside the bladder to make sure that the tumor(s) did not return. If there is no recurrence of tumors, they usually wait a few weeks after the scope, then start the BCG maintenance treatments. If the scopes are all clear, then the Maintenance treatments are usually 1x a week for 3 weeks at 3 months, 6 months, 12 months, 18 months, 24 months, 30 months, 36 months, and then some.
I hope this helps,
Take Care,
