Brief summary

RATIONALE: Stereotactic radiosurgery can send x-rays directly to the tumor and cause less damage to normal tissue. PURPOSE: This clinical trial studies stereotactic radiosurgery using CyberKnife works in treating women with advanced or recurrent gynecological malignancies.

Detailed description

PRIMARY OBJECTIVES: I. The primary goal of this study is to estimate the rate of grade 3 or higher acute toxicities observed during a 6 month period following CyberKnife radiosurgery for gynecologic cancers. II. To evaluate clinical response to radio-surgery for gynecologic tumors. III. To assess general and site specific quality of life (using SF-12, FACT-En, FACT-O, FACT-Cx or FACT-V) and to evaluate patient's level of pain. SECONDARY OBJECTIVES: I. As a secondary objective, toxicities during the 2 years following CyberKnife radiosurgery will also be described. OUTLINE: Patients undergo 3 fractions of CyberKnife stereotactic radiosurgery. After completion of study treatment, patients are followed at 1, 3, 6, 12, 18 and 24 months.

Interventions

RADIATIONstereotactic radiosurgery

Radiation will be delivered in 3 fractions. The dose level will range between 500 to 800cGy per fraction at the discretion of the treating radiation oncologist

Inclusion criteria

Inclusion * Pathologically proven gynecologic malignancy * No prior cryosurgery or radiofrequency ablation, in target lesion * Patient is able to give and sign study specific informed consent * Measurable disease, according to RECIST criteria * Laboratory parameters and appropriate clearance from anesthesia based on other medical co-morbidities for placement of fiducials; these would include CBC, basic metabolic panel, BUN, and creatinine * \>= 4 weeks from previous treatment (chemotherapy or radiation) of malignancy * ECOG performance status of 0-3 as this procedure is minimally invasive and considered palliative in these patients Exclusion * Any patient with active connective tissue disease such as lupus or dermatomyositis is excluded * Any patient with active Crohn's disease or active ulcerative colitis is excluded * Major medical or psychiatric illness, which would prevent completion of treatment or interfere with follow-up is excluded
