Eligibility criteria

Reproduced verbatim from the official record. Eligibility is decided by the study team, never by this page.

Inclusion Criteria:

* Patients must have a locally advanced and unresectable or metastatic gastroenteropancreatic neuroendocrine carcinoma that is either known or suspected to be of gastrointestinal (GI) origin; primary tumors arising from the lung, gynecologic organs or prostate are not permitted
* Patients must have pathologically/histologically confirmed tumor of non-small cell histology
* Patients must have a Ki-67 proliferative index of 20-100% OR at least 10 mitotic figures per 10 high powered fields
* Patients must have measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria; baseline measurements and evaluations of all sites of disease must be obtained within 4 weeks prior to randomization and must be acquired by multiphasic computed tomography (CT) or contrast magnetic resonance imaging (MRI)

  * NOTE: positron emission tomography (PET)-CT scans are allowed provided the CT portion of the exam is equivalent to a diagnostic CT scan and includes both oral and IV contrast
* Any prior surgeries must have been completed at least 4 weeks prior to randomization
* Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
* Patients may not be receiving any other investigational agents while on study treatment
* Patients may not be receiving Coumadin while on treatment; other anticoagulants are allowed
* Leukocytes \>= 3,000/mm\^3
* Absolute neutrophil count \>= 1,500/mm\^3
* Hemoglobin \>= 9 g/dL
* Platelets \>= 100,000/mm\^3
* Total bilirubin =\< institutional upper limit of normal (ULN) or =\< 1.5 X institutional ULN (if the patient has liver metastases)
* Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 X institutional ULN or (=\< 5 X institutional ULN if the patient has liver metastases)
* Serum creatinine =\< 1.5 X institutional ULN and creatinine clearance \>= 60 ml/min

  * NOTE: creatinine clearance must be calculated using the Cockcroft-Gault equation
* Patients must have a life expectancy of \>= 12 weeks as determined clinically by the treating physician
* Patients with impaired decision-making capacity may participate in the study if a legal authorized representative is available to consent
* Women of childbearing potential and sexually active males must be strongly advised to use an accepted and effective method of contraception or to abstain from sexual intercourse for the duration of their participation in the study
* Patients must be able to swallow pills
* Patients must be able to tolerate CT or magnetic resonance (MR) imaging including contrast agents as required for the treatment and the protocol

Exclusion Criteria:

* Patients may not have had any prior systemic treatment for this malignancy (for example chemotherapy or somatostatin analogues); prior palliative radiation is permitted but radiated lesions may not be used for measurement
* Patients may not have received any of the protocol agents within 5 years prior to randomization
* Patients with brain metastases (either remote or current) or presence of carcinomatous meningitis are not eligible
* Patients with known dihydropyrimidine dehydrogenase (DPD) deficiency will be excluded
* Patients must NOT have active or uncontrolled infection, symptomatic heart failure, unstable angina pectoris, cardiac arrhythmia or a serious psychiatric illness/social situation that would limit compliance with study requirements
* Patients must NOT have a history of allergic reactions attributed to compounds of similar chemical or biochemical composition to cisplatin, carboplatin, etoposide, temozolomide or capecitabine
* Patients must NOT have absorption issues that would limit the ability to absorb study agents
* Patients with a history of the following within =\< 12 months of study entry are not eligible:

  * Arterial thromboembolic events
  * Unstable angina
  * Myocardial Infarction
* Patients with symptomatic peripheral vascular disease are not eligible
* Patients must NOT have previous or concurrent malignancy; exceptions are made for patients who meet any of the following conditions:

  * Non-melanoma skin cancer, in situ cervical cancer, superficial bladder cancer, or breast cancer in situ OR
  * Prior malignancy completely excised or removed and patient has been continuously disease free for \> 5 years OR
  * Prior malignancy cured by non-surgical modalities and patient has been continuously disease free for \> 5 years
* Women must not be pregnant or breast-feeding

  * All females of childbearing potential must have a blood test or urine study within 2 weeks prior to randomization to rule out pregnancy
  * A female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
* Patients who are known to have human immunodeficiency virus (HIV) or are on combination antiretroviral therapy are ineligible
