Eligibility Criteria

Inclusion

  • INCLUSION CRITERIA:
  • Patients must have histologically confirmed locally recurrent adenocarcinoma of the prostate after prior radiation (external beam radiation therapy (EBRT) or brachytherapy).
  • Prostate-specific antigen (PSA) failure after definitive radiation as defined by the Phoenix criteria (PSA elevation at least 2 nanograms (ng) per deciliter (dL) above post-radiotherapy nadir)

  • Biochemical recurrence within one year of completion of radiotherapy
  • Need for chronic anticoagulation therapy (chronic low dose aspirin is not an exclusion)
  • Pre-existing and ongoing radiation-related grade 3 bowel or bladder toxicity

  • Serum creatinine \> 2 times the upper limit of normal
  • Total bilirubin \> 2 times the upper limit of normal OR in patients with Gilbert's syndrome, a total bilirubin \> 3.0.
  • Liver transaminases (alanine aminotransferase (ALT), aspartate aminotransferase (AST) greater than 3 times the upper limit of normal
  • Patients with positive Human Immunodeficiency Virus (HIV) status and currently requiring treatment with agents known to sensitize to irradiation, such as protease inhibitors.
