Phase I Stereotactic Body Radiation for Metastatic or Recurrent Platinum-Resistant Ovarian Cancer

PRIMARY OBJECTIVES: I. Evaluate response of platinum-resistant ovarian cancer to stereotactic body radiation therapy (SBRT) using fludeoxyglucose F 18 (18F-FDG) positron emission tomography (PET)/computed tomography (CT) 3 months after therapy. II. Determine the rate of grade 3 or greater non-hematologic acute toxicity from SBRT using Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. SECONDARY OBJECTIVES: I. Evaluate response to SBRT using cancer antigen-125 (CA-125) and symptom assessment using Functional Assessment of Cancer Therapy (FACT)-Ovarian Symptom Index (FOSI). II. Determine the rate of late and non-grade 3 acute toxicity using CTCAE version 4.0. III. Evaluate local control, progression-free survival, and overall survival following SBRT. OUTLINE: Patients undergo SBRT 5 days a week for approximately 1 week in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 6 weeks, 3, 6, 9, and 12 months, and then every 6 months for 4 years.
