Brief summary: RATIONALE: Everolimus may stop the growth of stomach or esophageal cancer by blocking blood flow to the tumor. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing, or by stopping them from spreading. Giving everolimus together with combination chemotherapy may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of everolimus when given together with combination chemotherapy in treating patients with metastatic stomach or esophageal cancer that has spread to other places in the body.

Detailed description: OBJECTIVES:

I. To determine the maximum tolerated dose of everolimus to use in combination with mFOLFOX6 \[oxaliplatin, leucovorin (leucovorin calcium), 5-FU (fluorouracil)\].

II. To better describe the toxicities associated with the combination of everolimus with mFOLFOX6.

III. To assess response rate and progression-free survival in this patient population.

IV. To assess overall survival in patients with metastatic gastric, esophageal and gastroesophageal junction (GEJ) adenocarcinoma treated with the combination of mFOLFOX6 + everolimus.

OUTLINE: This is a dose-escalation study of everolimus. Patients receive fluorouracil intravenously (IV) continuously over 46 hours, leucovorin calcium IV over 2 hours, and oxaliplatin IV over 2 hours on day 1. Patients also receive oral everolimus once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically for 1 year.

Eligibility criteria: Inclusion Criteria:

* Patients must have histologically confirmed diagnosis of gastric, esophageal, and GEJ adenocarcinoma
* Patients must have metastatic disease
* Patients must not have received any chemotherapy for metastatic disease
* Patients may have received prior adjuvant chemotherapy; completion of chemotherapy must be greater than 6 months from date of recurrent disease
* Patients must have computed tomography (CT) or magnetic resonance imaging (MRI) scan; patients must have at least one measurable site of disease according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria that has not been previously irradiated; if the patient has had previous radiation to the marker lesion(s), there must be evidence of progression since the radiation
* Patients must have a ECOG Performance Status of 0-1
* Absolute neutrophil count (ANC) \> 1,500/mcl
* Platelet count \> 100,000/mcl
* Hemoglobin (Hg) \> 9 g/dL
* Serum creatinine \< 1.5 mg/dl and/or Creatinine clearance \> 60 cc/min

* Serum glutamic oxaloacetic transaminase (SGOT) and/or serum glutamic pyruvic transaminase (SGPT) =\< 2.5 x institutional upper limit of normal (IULN) (=\< 5 x upper limit of normal \[ULN\] in patients with liver metastases)
* Fasting serum cholesterol =\< 300 mg/dL or =\< 7.75 mmol/L
* Fasting triglycerides =\< 2.5 x ULN; NOTE: in case one or both of these thresholds are exceeded, the patient can only be included after initiation of appropriate lipid lowering medication
* Patients should have controlled diabetes as evidenced by hemoglobin (Hb)A1C =\< 8%

* Due to the possibility of harm to a fetus or nursing infant from this treatment regimen, patients must not be pregnant or nursing (or plan to become pregnant); women and men of reproductive potential must have agreed to use a highly effective contraceptive method for at least 8 weeks after treatment
* Patients with risk factors for contraction hepatitis B or C should undergo screening prior to treatment on protocol. Patients with detectable viral titers are required to receive treatment for 4 weeks prior to starting protocol therapy.
* Patients must be able to swallow pills
* No other prior malignancy within the past 3 years is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years
* All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines
* Patients must have pathology specimen available for submission

Exclusion Criteria:

* Patients currently receiving anticancer therapies or who have received anticancer therapies within 4 weeks of the start of study drug (including chemotherapy, radiation therapy, antibody based therapy, etc)
* Patients who have received prior treatment with an mammalian target of rapamycin (mTOR) inhibitor (sirolimus, temsirolimus, everolimus)
* Patients with a known hypersensitivity to everolimus or other rapamycins (sirolimus, temsirolimus) or to its excipients
