title: Intravesical bacille Calmette-Guérin therapy for muscle invasive bladder cancer.
abstract: OBJECTIVE
  This investigation attempted to determine whether the degree of fibronectin expression in the bladders of patients with invasive transitional cell carcinoma correlated with their clinical response to intravesical bacille Calmette-Guerin (BCG) therapy.
  
  
  METHODS
  Following transurethral resection of all invasive disease, 13 patients with Stages T2-T4 bladder cancer were administered intravesical BCG (fo 6 weeks followed by monthly instillations). Fibronectin expression in the patients' resected tumors and normal mucosa was determined by immunohistochemical staining techniques. Minimum disease-free follow-up was 60 months.
  
  
  RESULTS
  Only 1 of 13 patients had neither local nor systemic disease recurrence; 10 of 13 patients developed systemic disease and 7 patients died from metastases. Fibronectin expression was not correlated with the clinical response to BCG.
  
  
  CONCLUSIONS
  Intravesical BCG therapy for the treatment of muscle invasive transitional cell carcinoma of the bladder is ineffective. Fibronectin expression in the bladder of patients with invasive disease is variable and does not correlate significantly with the clinical response to BCG therapy.
