Thankyou for all the comments here, very helpful.
My experience here in Australia has been similar. After the 2nd TURB necessitated to clarify the extent of high grade CIS the pathology indicated Stage 1. However the oncologist was concerned about the extent of CIS and explained that an extremely radical approach would be to go for removal. Having said that, he did say that post operative investigations on removed bladders indicate that in 50% of cases there had been no need for removal. His comment on BCG was that it had an excellent chance of success with only a 35% chance of some recurrence in 5 years. (Normally 25% but my situation seemed to be worse). He consulted his peers and they collectively recommended BCG plus a comprehensive and frequent monitoring program. Following 2 TURBS and 9 BCGs I have since had 2 scopes over 6 months both showing no active cancer. I will have another scope in Aug and 3 more BCGs in Oct.
His comment on removal, due to my interest in the 'final solution', was that a second opinion would be great BUT BEWARE WHO GAVE IT. He warned that sadly there are some who would jump at the chance of a privately insured patient to practice their surgical skills at my expense and leave me with life changing results albeit with no cancer. Being UK trained he said he took his Hypocratic Oath to 'do no harm' seriously, and would only advise BCG in my situation. I shall ever be grateful to him.
