- "BCG" as a Bladder Cancer Treatment
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: After the necessary tests and biopsy, I am told by my doctor that I
- have a type of bladder cancer that should respond to a new treatment called
- "BCG". I understand that this is a bacteria that causes tuberculosis, and do
- not understand how this is used to treat my disease. I can't find any
- information about it, and hope you may be able to explain it to me. Please!

- ANSWER: Little wonder that you are confused, for this is a brand new
- development in the treatment of a type of a carcinoma of the bladder known as
- carcinoma-in-situ. The medication just recently approved for this use by the
- Food and Drug Administration is called TheraCys, and is manufactured by
- Connaght Laboratories Limited of Toronto, Canada. The letters "BCG" stand
- for the "bacillus of Calmette and Geurin," two French researchers who cultured
- a strain tuberculosis bacteria in eggs until it lost its ability to produce
- the disease in man but could still stimulate the immune response. Though it
- was first used as a vaccine for this purpose in 1924, it is still considered
- controversial, and while it is used in most third world countries, it is not
- widely used in the United States. In 1976, Dr. Alvero Morales of Queen's
- University in Kingston, Ontario, documented that a different formulation and
- concentration of BCG was effective in the treatment of bladder cancer
- patients. The treatment begins from 7 to 14 days after a biopsy or bladder
- surgery, when the medication is placed into the bladder itself. This is
- repeated each week for six weeks (induction therapy), after which it is
- followed up by a maintenance schedule given at 3, 6, 12, 18 and 24 months
- following the initial treatment. The most common adverse reactions are
- flu-like symptoms including fever, chills and malaise. The clinical studies
- showed a average complete response rate, that is no recurrence of tumors, of
- 74 percent, as compared to 42 percent with adriamycin, another cancer fighting
- drug.
