This trial studies the side effects of partial brain radiation therapy, temozolomide, chloroquine, and tumor treating fields therapy for the treatment of newly diagnosed glioblastoma. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Chloroquine is normally used to treat strains of malaria and prior preclinical and clinical data suggests that it may increase the efficacy of both radiation and tumor treating fields therapy. Tumor treating fields therapy uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and potentially causing cancer cells to die. The purpose of this study is to determine the safety of partial brain radiation therapy, temozolomide, chloroquine, and tumor treating fields therapy in patients with gliobastoma
PRIMARY OBJECTIVE:
I. To determine the safety of partial brain radiation therapy plus temozolomide and chloroquine followed by tumor treating fields (TTFs) plus temozolomide and chloroquine, specifically grade 3 or higher dermatitis within the first 3 months of the adjuvant therapy phase.
SECONDARY OBJECTIVE:
I. To measure treatment effect via advanced magnetic resonance imaging (MRI) and alpha-[11C]methyl-L-tryptophan (AMT)-positron emission tomography (PET).
OUTLINE:
Patients undergo 30 fractions of 3-dimensional conformal radiation therapy (3D CRT) or intensity-modulated radiation therapy (IMRT) and receive temozolomide orally (PO) and chloroquine PO daily from day 1 for the duration of radiation therapy up to day 49. Treatment continues in the absence of disease progression or unacceptable toxicity.
ADJUVANT TREATMENT: Beginning 4 weeks after the last day of radiation therapy, patients receive temozolomide PO once daily (QD) on days 1-5 and chloroquine PO daily on days 1-28. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients demonstrating continued benefit may continue to receive temozolomide and chloroquine for up to 12 cycles. Patients also undergo TTF therapy over 18 hours or longer per day.
After completion of study treatment, patients are followed up monthly for 3 months.

Female subjects of childbearing potential (i.e., those who are not postmenopausal for at least 1 year or surgically sterile by bilateral tubal ligation, bilateral oophorectomy or hysterectomy) and their male partners should practice at least one of the methods of birth control listed below during study entry, for the entire duration of the study and for at least 6 months after treatment with temozolomide and chloroquine:
* A vasectomized male subject or a vasectomized partner of a female subject; hormonal contraceptives (oral, parenteral, or transdermal) for at least 3 months prior to study drug administration; intrauterine device (females); double-barrier method (condoms, contraceptive sponge, diaphragm or vaginal ring with spermicidal jellies or cream)
Exclusion Criteria:
Severe, active, co-morbidity defined as follows:
* Moderate or severe hepatic impairment (Child-Pugh category B or higher [score of 7 or higher ]); unstable angina and/or congestive heart failure within the last 6 months; transmural myocardial infarction within the last 6 months; evidence of recent myocardial infarction or ischemia by the findings of S-T elevations of >= 2 mm using the analysis of an electrocardiogram (EKG) performed within 14 days prior to enrollment; New York Heart Association grade II or greater congestive heart failure requiring hospitalization within 12 months prior to enrollment
Patients undergo 30 fractions of 3D CRT or Intensity-modulated radiation therapy (IMRT) and receive temozolomide by mouth (PO) and chloroquine PO daily from day 1 for the duration of radiation therapy up to day 49. Treatment continues in the absence of disease progression or unacceptable toxicity. ADJUVANT TREATMENT: Beginning 4 weeks after the last day of radiation therapy, patients receive temozolomide PO QD on days 1-5 and chloroquine PO daily on days 1-28. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients demonstrating continued benefit may continue to receive temozolomide and chloroquine for up to 12 cycles. Patients also undergo TTF therapy over 18 hours or longer per day.
