Brief Summary:

Rationale: Broccoli sprout extract contains ingredients that may prevent or slow the growth of certain cancers.

Purpose: This pilot study is studying the side effects of broccoli sprout extract in treating patients with transitional cell bladder cancer undergoing surgery.

Condition or disease Intervention/treatment Phase
Recurrent Bladder Cancer Stage 0 Bladder Cancer Stage I Bladder Cancer Stage II Bladder Cancer Transitional Cell Carcinoma of the Bladder Drug: broccoli sprout extract Other: laboratory biomarker analysis Other: Mango Juice Not Applicable

Detailed Description:

Primary Objectives:

I. To determine the tolerability and toxicity of a broccoli sprout extract (providing 200 micro mol isothiocyanate/dose/per day) given for 14 days in patients destined to undergo definitive bladder resection for bladder cancer.

Secondary Objectives:

I. Establish the safety of administration of the broccoli extract on the bladder surgery specifically.

II. Determine the levels of isothiocyanates and their metabolites in urine, blood, benign urothelium and bladder cancer tissue.

III. Assess the antitumor effects of broccoli extract on the primary bladder tumor by measuring angiogenesis, cell proliferation and apoptosis.

IV. Determine the feasibility of treating patients with 200 micro mol isothiocyanate per dose per day of broccoli sprout extract in future therapeutic and prevention clinical trials.

Outline: Patients receive oral broccoli sprout extract once daily on days 1-14 in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed at 4 weeks.

Inclusion Criteria:

  • Any patient eligible for superficial bladder cancer
  • Patients must be considered fit for surgical resection with curative intent

Exclusion Criteria:

  • Have participated in any clinical trial involving conventional or investigational drugs or devices within the previous 4 weeks
  • Prior radiation to the pelvis
  • Intractable urinary tract infection that has not responded to antibiotic treatment
  • Active, uncontrolled bacterial, viral, or fungal infection including HIV
  • Have had major surgery within 4 weeks of starting therapy (not including placement of vascular access device or TURBT)
  • Poor medical risk in the opinion of the treating oncologist due to non-malignant systemic disease
  • Pregnant or lactating patients: patients must be postmenopausal or practicing an accepted form of birth control; for patients where pregnancy is a possibility, a pregnancy test will be required prior to initiation of therapy
  • Have a history of myocardial infarction or angina pectoris/angina equivalent in the last 6 months (the patient may be on anti-anginal medications if the symptoms have been entirely controlled for greater than 6 months), or have uncontrolled congestive heart failure
  • Have a history of bleeding disorders or thrombosis; patients on therapeutic doses of anticoagulation (including coumadin or heparins) are not permitted on trial (this exclusion criterion does not include those patients receiving low dose or prophylactic dose anticoagulation [i.e. coumadin 1 mg daily in patients with central intravenous lines])
  • Radiotherapy during the course of the trial
  • Inability to tolerate proposed treatment or procedures
  • Have additional uncontrolled serious medical conditions or psychiatric illness
  • Patients with a history of hepatitis (including but not exclusive to viral hepatitis auto-immune or alcoholic)
