Cysview is an optical imaging agent used to detect non-muscle invasive bladder cancer in patients suspected or known to have lesion(s) on the basis of a prior cystoscopy, or in patients undergoing surveillance cystoscopy for bladder cancer. Cysview is not a replacement for random bladder biopsies or other procedures used in the detection of bladder cancer. False-positive fluorescence may occur due to inflammation, trauma from past cystoscopies, scar tissue, previous bladder biopsy, and recent Bacillus Calmette-Guérin (BCG) therapy or intravesical chemotherapy.
Anaphylactoid shock, hypersensitivity reactions, bladder pain, bladder inflammation (cystitis), and abnormal urine tests have been reported after administration of Cysview. The most common adverse reactions seen in clinical trials were bladder spasm, trouble urinating, discomfort when urinating, frequent urination, blood in the urine, and bladder pain.
Cysview should not be used in patients with large amounts of blood in their urine, any known allergy to Cysview or any derivative of aminolevulinic acid, or porphyria, a condition that means you already have high levels of porphyrins in your body. No specific drug interaction studies have been performed.
There are no available data on Cysview use in pediatric patients, pregnant women, or nursing mothers.

Bacillus Calmette-Guérin (BCG) is an immunotherapy that is put into the bladder directly to treat early-stage bladder cancer (NMIBC).1
Immunotherapies work by causing the body’s immune system to attack the cancer cells.1

Not all bladder cancer is the same so to help identify it and decide the best treatment option, it is classified according to stage and grade.1
Stage is determined by how far the cancer has gone into the bladder wall and spread, with the stages as follows:1
T0: No tumor
Ta: Papillary tumor without invading the bladder wall
TIS (CIS): Carcinoma in situ (non-invasive flat high-grade (G3) cancer)
T1: Tumor invades the connective tissue under the surface lining
T2: Tumor invades the muscle layer
T3: Tumor penetrates the bladder wall and invades the surrounding fat layer
T4: Tumor invades other organs (i.e., prostate, uterus, vagina, pelvic wall)
Grade is expressed as a number between 1 (low) and 3 (high, i.e., G3); the higher the number, the more the tumor is abnormal. Your urologist, however, may refer to the tumor as either low grade or high grade instead of using a number.1

TURBT is a surgical procedure where a urologic oncologist removes tumors from the bladder wall. The procedure is performed under general anesthesia in the operating room.1
