How often are BCG treatments given?
BCG is given once a week for six weeks, starting 2–4 weeks after TURBT surgery. It is put directly into the bladder through a catheter. You may be asked to change position every 15 minutes so the vaccine washes over the entire bladder. Each treatment session takes up to two hours.

Treatment with BCG can cause a wide range of symptoms. It’s common to have flu-like symptoms, such as fever, achiness, chills, and fatigue. These can last for 2 to 3 days after treatment. It also commonly causes a burning feeling in the bladder, the need to urinate often, and even blood in the urine.
What is the success rate of BCG treatment?
A recent study was published evaluating maintenance BCG therapy [23]. The authors observed a three-year recurrence free survival of 75.3% and disease-free survival of 96.1%. However, they reported a high complication rate of 81.5%.
How successful is BCG treatment?
How is intravesical Tice used to treat bladder cancer?
Intravesical TICE BCG has been used as a therapy for, and prophylaxis against, recurrent tumors in patients with carcinoma in situ (CIS) of the urinary bladder, and to prevent recurrence of Stage TaT1 papillary tumors of the bladder at high risk of recurrence. The precise mechanism of action is unknown.
When to take Tice BCG after bladder biopsy?
In addition, use only sterile, preservative-free saline, 0.9% Sodium Chloride Injection USP as diluent. Allow 7 to 14 days to elapse after bladder biopsy before TICE BCG is administered. Patients should not drink fluids for 4 hours before treatment and should empty their bladder prior to TICE BCG administration.
How long does Tice stay in the bladder?
The reconstituted TICE® BCG is instilled into the bladder by gravity flow via the catheter. DO NOT depress plunger and force the flow of the TICE® BCG. The TICE® BCG is retained in the bladder 2 hours and then voided. Patients unable to retain the suspension for 2 hours should be allowed to void sooner, if necessary.
Is there a TICE strain for intravesical use?
TICE® BCG for intravesical use, is an attenuated, live culture preparation of the Bacillus of Calmette and Guerin (BCG) strain of Mycobacterium bovis.1 The TICE® strain was developed at the University of Illinois from a strain originated at the Pasteur Institute.
