Bevacizumab in Treating Patients With Recurrent Sex Cord-Stromal Tumors of the Ovary

Inclusion Criteria

• Patients diagnosed with histologically confirmed recurrent ovarian stromal tumor (granulosa cell tumor, granulosa cell-theca cell tumor, Sertoli-Leydig cell tumor [androblastoma], steroid [lipid] cell tumor, gynandroblastoma, unclassified sex cord-stromal tumor, sex cord tumor with annular tubules)
• Patients must have measurable disease by Response Evaluation Criteria In Solid Tumors (RECIST) criteria
• Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded); each ?target? lesion must be >= 20 mm when measured by conventional techniques, including palpation, plain x-ray, computed tomography (CT), and magnetic resonance imaging (MRI), or >= 10 mm when measured by spiral CT
• Patients must have a Gynecologic Oncology Group (GOG) performance grade of 0, 1, or 2
• Patients of childbearing potential must have a negative pregnancy test and must agree to practice an effective means of birth control
• Patients who have met the pre-entry requirements specified
• There are no restrictions on prior therapy; however, patients cannot have previously had treatment with bevacizumab
• Absolute neutrophil count (ANC) >= 1,000/?l
• Platelets greater than or equal to 75,000/?l
• Creatinine = 150 mm Hg or diastolic > 90 mm Hg
• Myocardial infarction or unstable angina within 6 months prior to registration
• New York Heart Association (NYHA) grade II or greater congestive heart failure
• Serious cardiac arrhythmic requiring medication.
• Grade 2 or greater peripheral vascular disease
• Patients with GOG performance grade of 3 or 4
• Patients with clinically significant peripheral arterial disease; e.g., claudication within 6 months
• Patients with known hypersensitivity to Chinese hamster ovary cell products or other recombinant human or humanized antibodies
• Patients with clinically significant proteinuria; urine protein should be screened by urine protein-creatinine ratio (UPCR); the UPCR has been found to correlate directly with the amount of protein excreted in a 24 hour urine collection; specifically; a UPCR of 1.0 is equivalent to 1.0 gram of protein in a 24 hour urine collection; obtain at least 4 ml of a random urine sample in a sterile container (does not have to be a 24 hour urine); send sample to lab with request for urine protein and creatinine levels (separate requests); the lab will measure protein concentration (mg/dL) and creatinine concentration (mg/dL); the UPCR is derived as follows: protein concentration (mg/dL)/creatinine (mg/dL); patients must have a UPCR < 1.0 to allow participation in the study
• Patients with a history of cardiovascular accident (CVA) within 6 months prior to registration
• Patients with any signs of bowel obstruction or patients who require parenteral hydration and/or nutrition
• Patients whose circumstances do not permit completion of the study or the required follow-up
• Patients who are pregnant or nursing; patients who may become pregnant must agree to use contraceptive measures during the study and for at least 3 months after the completion of bevacizumab therapy
• Patients who have a major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to the first date of treatment on this study, or anticipate the need for major surgical procedure during the course of the study; patients with placement of vascular access device or core biopsy within 7 days prior to the first date of treatment on this study
• Patients with active infection requiring parenteral antibiotics
• Patients with a history of other invasive malignancies, with the exception of non-melanoma skin cancer, are excluded if there is any evidence of other malignancy being present within the last five years; patients are also excluded if their previous cancer treatment contraindicates this protocol therapy
