RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Biological therapies such as BCG use different ways to stimulate the immune system and stop cancer cells from growing. It is not yet known whether AD 32 is more effective with or without BCG after surgery for superficial bladder cancer.
PURPOSE: Randomized phase II trial to compare the effectiveness of AD 32 with or without BCG after surgery in treating patients who have newly diagnosed or recurrent superficial bladder cancer.
- Evaluate the efficacy of peri-operative intravesical AD 32 alone or supplemented with BCG in patients with newly diagnosed or recurrent superficial bladder cancer characterized as either high risk or low risk based on the tumor markers p53 and pRb.
- For low-risk patients, assess the efficacy of peri-operative AD 32 in preventing tumor recurrence.
- For high-risk patients, assess the efficacy of combined intravesical therapy with AD 32 administered within 8 hours after transurethral resection along with BCG in decreasing the incidence of tumor progression.
- Evaluate systemic exposure and urine recovery of AD 32 through pharmacokinetic analysis in a subset of patients.
OUTLINE: This is a randomized, open-label study.
All patients undergo complete transurethral resection to remove bladder tumors. AD 32 is administered by catheter into the bladder within 8 hours after surgery. Patients must hold the AD 32 in the bladder for 90 minutes.
After pathological and tumor marker analysis, patients are assigned to the low or high-risk group as defined by their p53 and pRb phenotype.
- Low risk: Patients with carcinoma in situ receive BCG by catheter into the bladder once weekly for 6 weeks beginning 7-21 days after treatment with AD 32. Patients assigned to the low-risk group who do not have carcinoma in situ receive no further treatment.
- High-risk: Patients also receive BCG once weekly for 6 weeks and then once weekly for 3 weeks at 3 months, 6 months, and then every 6 months for a total of 3 years after the first BCG treatment.
All patients undergo cystoscopy every 3 months for the first year and then every 6 months for the next 2 years.
PROJECTED ACCRUAL: Approximately 200 patients will be accrued for this study.

To monitor the quality of bladder cancer care, the Swedish National Register of Urinary Bladder Cancer (SNRUBC) was initiated in 1997. During 2015, in order to study trends in incidence, effects of tr...
To evaluate the diagnostic accuracy of the Xpert Bladder Cancer (BC) Monitor, compared to cystoscopy and cytology in the oncological follow-up of non-muscle invasive bladder cancer (NMIBC).
Molecular markers of clinical outcome may aid in designing targeted treatments for bladder cancer. However, only a few bladder cancer biomarkers have been examined as therapeutic targets.
Bladder cancer is a common disease with a stable incidence for the past few decades despite advancements in molecular and genetic determinants of cancer development and progression. Cystoscopy remains...
Tetrandrine and Fangchinoline (Fcn) are two natural products that are found in Stephania tetrandra. Tetrandrine is a known anti-bladder cancer compound, but the effects of Fcn on bladder cancer have b...
Tumors or cancer of the URINARY BLADDER.
A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.
A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)
A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
A live attenuated virus vaccine of chick embryo origin, used for routine immunization of children and for immunization of adolescents and adults who have not had mumps or been immunized with live mumps vaccine. Children are usually immunized with measles-mumps-rubella combination vaccine.
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
