Title: A Phase III Prospective Randomized Trial Comparing Radiosurgery With Versus Without Whole Brain Radiotherapy for 1-3 Newly Diagnosed Brain Metastases
Brief Summary: The goal of this clinical research study is to learn if your thinking ability (cognitive function) will be better preserved by delivering whole brain radiation therapy immediately after radiosurgical treatment of 1-3 brain metastases or to carefully observe patients after radiosurgery and hold back whole brain radiation therapy until the disease comes back.


Options:
A: INCLUSION CRITERIA:

* Histologically or cytologically confirmed non-hematopoietic malignancy within the past 5 years

  * If histologic proof of malignancy is from \> 5 years ago, then a more recent pathological confirmation is required (e.g., from systemic metastatic or brain metastasis)
  * Patients with metastasis of unknown primary tumor are permitted
* Measurable brain metastasis outside a 5-mm margin around either hippocampus on gadolinium contrast-enhanced MRI obtained within the past 30 days
* Have not been or will not be treated with stereotactic radiosurgery (SRS) or surgical resection

  * These treatment options are allowed only at relapse
* Patients who have brain metastases at initial presentation allowed and do not need to demonstrate 3 months of stable scans
* At least 1 week since open biopsy
* Karnofsky performance status 70-100%
* Fertile patients must use effective contraception
* Negative pregnancy test 2 weeks or less prior to study entry
* Patients must be English proficient, with patients who speak English as a second language eligible

EXCLUSION CRITERIA:

* Small cell lung cancer or germ cell malignancy
* Leptomeningeal metastases
* Non-small cell lung cancer-associated brain metastases with ≥ 2 organ sites of extracranial metastases
* Radiologic evidence of hydrocephalus
* Serum creatinine \> 1.4 mg/dL within 30 days prior to study entry
* Pregnant or nursing
* Contraindication to MRI imaging such as implanted metal devices or foreign bodies or severe claustrophobia
* Severe, active co-morbidity including any of the following:

  * Unstable angina and/or congestive heart failure requiring hospitalization within the past 6 months
  * Transmural myocardial infarction within the past 6 months
  * Acute bacterial or fungal infection requiring intravenous antibiotics
  * Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects
  * Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy
  * Uncontrolled, clinically significant cardiac arrhythmias
* Prior radiotherapy to the brain
* Plan for chemotherapy or targeted therapies during WBRT or during the subsequent 7 days
B: Inclusion Criteria:

* age \>= 18 years
* recurrence of a histologically confirmed glioblastoma or gliosarcoma
* at least 6 months after first surgery
* at least 6 months after first radiotherapy
* interdisciplinary recommendation for reirradiation
* karnofsky performance status \>= 60, ECOG \<= 2
* creatinine \<= 2,0 mg/dl, urea \<= 100 mg/dl
* ALAT, ASAT \<= 7x upper normal limit

Exclusion Criteria:

* bowel obstruction, subileus
* insulin-dependent diabetes
* decompensated heart failure (NYHA \> 2)
* myocardial infarction within the last 6 months, symptomatic atrial fibrillation
* severe acute infection
* malnutrition, cachexia
* other medical conditions that might increase the risk of the dietary intervention
* pregnancy
* uncontrolled thyroid function
* pancreatic insufficiency
* dementia or other clinically relevant alterations of the mental status which could impair the ability of the patient to apply to the diet or understand the informed consent of the study
C: Inclusion Criteria:

1. age 18 or older
2. fluent in English
3. able to provide informed consent to all procedures
4. diagnosis of a brain tumor
5. indication of lasting post-treatment cognitive deficits (e.g., from clinical presentation, prior neuropsychological assessment, and/or self-report)
6. sufficient motor and sensory functioning to complete study activities
7. availability to complete all study activities
8. for patients treated with cranial radiation, at least 3 months post-radiation

Exclusion Criteria:

(1) comorbid neurological or psychiatric disorder or other medical condition suspected to influence cognition
D: Inclusion Criteria:

1)age 18 and older at time of registration. 2) recursive partitioning class (RPA) I or II. 3) 1 to 3 newly diagnosed brain metastases 4) must be eligible to have all lesions treated by SRS as determined by the radiation oncologist on the basis of location and size. 5)MRI with contrast must be performed with 1 month of registration. 6)Signed informed consent form approved by the IRB agreeing to randomization .

Exclusion Criteria:

1) prior WBRT 2) prior resection of brain metastasis, SRS or Gamma knife. 3) \> 3 brain metastases present on MRI 4) lymphoma, small cell lung cancer, leukemia, germ cell tumors. 5) leptomeningeal disease. 6) unknown primary.7) RPA Class III (i.e. KPS \< 70) 8) pregnancy.

Post-entry exclusion: No post-entry exclusions will be allowed after registration has occurred. All randomized patients will be included in the analysis and those lost to follow-up will be assigned the least favorable outcome (recurrence, death).
