Spots Global Cancer Trial Database for Erlotinib Before and After Surgery in Treating Patients With Muscle-Invasive Bladder Cancer

Study Description

Brief Summary: RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erlotinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving erlotinib after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying how well erlotinib works when given before and after surgery in treating patients with muscle-invasive bladder cancer.

Detailed Description: OBJECTIVES: Primary * Determine the effect of neoadjuvant erlotinib hydrochloride on histopathological, molecular, and genetic correlates in patients undergoing radical cystectomy for muscle-invasive bladder cancer. Secondary * Determine the pathological complete response rate in surgical specimens from patients treated with this drug. * Determine recurrence and progression rates after cystectomy (up to 2 years after surgery) in patients treated with neoadjuvant and adjuvant erlotinib hydrochloride. * Determine 2- and 5-year disease-free, disease-specific, and overall survival rates in patients treated with this drug. * Determine the safety of this drug in these patients. OUTLINE: This is an open-label study. Patients receive oral erlotinib hydrochloride once daily for 4 weeks. Patients then undergo radical cystectomy with curative intent. Within 12 weeks after surgery, patients resume oral erlotinib hydrochloride\* once daily for up to 2 years in the absence of disease progression or unacceptable toxicity. Note: \*Patients who are candidates for adjuvant chemotherapy (e.g., found to have pathologic stage T3 (pT3), Node positive (N+) disease) do not receive erlotinib hydrochloride after surgery. Tumor tissue is obtained at baseline (at the original or confirmatory transurethral resection of the bladder tumor) and at the time of cystectomy for analysis of drug-specific and tissue-based biomarkers by western blot, immunohistochemistry, and gene array techniques. Histopathological, molecular, and genetic correlates are analyzed to better understand the potential effects of the epidermal growth factor receptor (EGFR) inhibition in transitional cell carcinoma and to determine the effect of neoadjuvant erlotinib on gene expression. Tumor tissue is also evaluated by real-time polymerase chain reaction to confirm drug effects on expected targets and on EGFR expression, activity, and affected signaling pathways in the disease state and by microarray analysis to define expression phenotypes correlating with outcome, distinguish responders from nonresponders, and determine effects of drug treatment on gene expression in disease. Patients are followed periodically for up to 5 years after surgery.
