Brief Summary
This phase II trial studies olaparib and temozolomide in treating patients with uterine leiomyosarcoma (LMS) that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), that has spread from where it first started to other places in the body (metastatic) or cannot be removed by surgery (unresectable). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. 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. Giving olaparib and temozolomide may work better than giving either drug alone in treating patients with LMS.

Outcome Measures
Primary Outcomes (1)
Confirmed Objective Response Rate (ORR) (Complete Response + Partial Response)
Will be measured by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria assessed by MRI: Complete Response (CR), disappearance of all target lesions, any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm (\<1 cm); Partial Response (PR), at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. A response rate of 10% is considered inactive and unworthy of further study. A response rate of 35% would be promising for further study among patients with advanced uterine leiomyosarcoma (LMS) treated with at least one prior systemic regimen. A response rate of 35% for the temozolomide (TMZ) + poly(adenosine diphosphate\[ADP\]-ribose) polymerase inhibitor (PARPi) combination would also be suggestive of superior efficacy over TMZ monotherapy in sarcoma. Will be reported with a 95% confidence interval.

Eligibility Criteria
You may qualify if:
- Patients must have histologically documented LMS of uterine origin. Pathology review and confirmation of diagnosis will occur at the site enrolling the patient on this study.
- Patients must have locally advanced and unresectable or metastatic disease.
- Patients must have disease which is measurable at study entry according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria. Additionally, patients must have a site of disease deemed accessible for biopsy at no or minimal risk to the patient (including through the use of image-guidance). If there are questions regarding the feasibility of biopsy, the case should be reviewed with interventional radiology or the appropriate department at the study site prior to registration.
- Patients must have had prior progression on, or intolerance to, at least one line of systemic therapy for advanced LMS. Adjuvant therapy administered after curative resection will not qualify as prior treatment. There is no upper limit on the number of prior therapies received.
- Patients must be \>= 18 years of age. Uterine LMS affects older adults and is rarely encountered in children and adolescents.
- Patients must demonstrate an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of =\< 2 (Karnofsky \>= 50%).
- Absolute neutrophil count \>= 1,500/mcL (measured within 14 days prior to administration of study treatment).
- Hemoglobin \>= 9 g/dL (without transfusion of packed red blood cells within the past 28 days) (measured within 14 days prior to administration of study treatment).
- Platelets \>= 100,000/mcL (measured within 14 days prior to administration of study treatment).
- Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN) (measured within 14 days prior to administration of study treatment).
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 x institutional ULN (measured within 14 days prior to administration of study treatment).
- Glomerular filtration rate (GFR) \>= 51 mL/min, based on a 24-hour urine test for creatinine clearance or estimated using the Cockcroft-Gault equation (measured within 14 days prior to administration of study treatment).
- If patients have evidence of chronic hepatitis B virus (HBV) infection, HBV viral load must be undetectable on suppressive therapy if indicated. Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody and absence of hepatitis B surface antigen \[HBsAg\]) are eligible.
- If patients have a history of hepatitis C virus (HCV) infection, they must be treated with undetectable HCV viral load (polymerase chain reaction is negative for HCV ribonucleic acid \[RNA\]).
- Patients must be postmenopausal or have evidence of non-childbearing status, OR, for women of childbearing potential, must have a negative urine or serum pregnancy test within 28 days of study treatment and confirmed again on day 1 prior to study treatment.
- +13 more criteria
You may not qualify if:
- Patients must not have had any previous treatment with any poly(adenosine diphosphate\[ADP\]-ribose) polymerase (PARP) inhibitors, including olaparib, or prior treatment with dacarbazine and/or temozolomide.
- Patients must have recovered from adverse events due to prior anti-cancer therapy (i.e., may not have residual toxicities \> grade 1 or above baseline), excluding alopecia. Patients who have endocrinopathies associated with prior immunotherapy treatment but which are controlled with replacement therapy are eligible.
- Prior to initiating study treatment, at least 28 days must have elapsed from the last dose of systemic anti-cancer treatment (cytotoxic, biologic or immunotherapeutic) or radiation therapy (except for palliative radiation, in which case a 14-day washout applies).
- Patients must not have had major surgery within 2 weeks of starting study treatment and must have recovered from any effects of any major surgery that occurred \> 2 weeks before starting study treatment.
- Patients must not be receiving any other investigational agent.
- Patients must not have been diagnosed with another malignancy unless curatively treated with no evidence of disease for \>= 5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), or any other malignant condition considered indolent and unlikely to require active therapy.
- Patients must not have myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or bone marrow biopsy findings consistent with MDS and/or AML.
- Patients must not have active central nervous system (CNS) or leptomeningeal disease at the time of enrollment. Patients with a history of such disease previously treated with curative intent (such as with surgery or radiation) that have not progressed on subsequent imaging, have been clinically asymptomatic, and have not received systemic corticosteroids for at least 28 days, are eligible.
- Patients must not have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to olaparib or TMZ or any of the excipients of any study product.
- Patients must refrain from concomitant use of known strong CYP3A inhibitors (e.g., itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g., ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period for strong or moderate CYP3A inhibitors prior to starting olaparib is 2 weeks. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product.
- Patients must refrain from concomitant use of known strong CYP3A inducers (e.g., phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's wort) or moderate CYP3A inducers (e.g., bosentan, efavirenz, modafinil). The required washout period for strong or moderate CYP3A inducers prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents.
- Patients must not have an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on high resolution computed tomography (HRCT) scan, or psychiatric illness that would limit compliance with study requirements.
- Pregnant women are excluded from this study because olaparib is a PARP inhibitor with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with olaparib, breastfeeding should be discontinued if the mother is treated with olaparib. These potential risks may also apply to other agents used in this study.
- Patients must not have gastrointestinal disorders likely to interfere with absorption of the study medication.
- Patients must not have had involvement in the planning and/or conduct of the study.
