Nivolumab and Multi-fraction Stereotactic Radiosurgery With or Without Ipilimumab in Treating Patients With Recurrent Grade II-III Meningioma

Inclusion Criteria

• •Patients must have histologically confirmed World Health Organization (WHO) grade II-III meningioma which has relapsed after prior radiation therapy with radiologically progressive or recurrent disease
• •Patients must have measurable disease, defined as at least 1 lesion that can be accurately measured in at least one dimension as \>= 1 cm on brain magnetic resonance imaging (MRI) but with the maximum dimension =\< 5 cm OR gross tumor volume \< 20 cm\^3. All the relapsed disease would need to be eligible to be treated with reirradiation
• •Patients must have at least one prior surgery with available archival formalin-fixed paraffin-embedded (FFPE) tumor blocks of the initial or recurrent meningioma. If there are multiple tumor blocks from multiple surgeries, the most recent tumor block (and ideally of the relapsed tumor after initial radiation therapy) should be submitted. If a tumor block is not available, an alternative of 20-30 unstained slides may be submitted instead. Annotation regarding whether the tumor block is before or after initial radiation therapy should be provided
• •Prior initial radiation therapy may include external beam radiation or radiosurgery, or combination of both. However, the total dose of prior radiation exposure to the site of recurrent tumor (for consideration of re-irradiation) cannot be more than 70 Gy. The duration since the previous radiation exposure to the site of reirradiation need to be at least 6 months
• •Age \>= 18 years
• •Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%)
• •Leukocytes \>= 3,000/mcL
• •Absolute neutrophil count \>= 1,500/mcL
• •Platelets \>= 100,000/mcL
• •Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN)
• •Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 x institutional ULN
• •Serum creatinine =\< 1.5 x institutional ULN OR glomerular filtration rate (GFR) \>= 30 mL/min/1.73 m\^2 for patients with creatinine levels above 1.5 x institutional normal
• •The effects of nivolumab and/or ipilimumab on the developing human fetus are unknown. For this reason and because radiation therapy is known to be teratogenic, women of childbearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. WOCBP should use an adequate method to avoid pregnancy for 5 months after the last dose of investigational drug. Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin \[HCG\]) within 24 hours prior to the start of nivolumab. Women must not be breastfeeding. Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of investigational product. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception
• •* Women of childbearing potential (WOCBP) is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level less than 40 mIU/mL
• •* WOCBP receiving nivolumab will be instructed to adhere to contraception for a period of 5 months after the last dose of investigational product. Men receiving nivolumab and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of investigational product. These durations have been calculated using the upper limit of the half-life for nivolumab (25 days) and are based on the protocol requirement that WOCBP use contraception for 5 half-lives plus 30 days and men who are sexually active with WOCBP use contraception for 5 half-lives plus 100 days
• •* Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
• •Ability to understand and the willingness to sign a written informed consent document or, if decision-making capacity is impaired, consent of a legally authorized representative (e.g., spouse, adult child, live-in caretaker).
