Eligibility Criteria:
Inclusion Criteria:
* Histologically confirmed mantle cell lymphoma (MCL); the diagnosis must be confirmed by NCCTG pre-registration pathology review by Dr. Paul Kurtin or his designate; it is recommended that the biopsy be an excisional biopsy, but adequate core-needle biopsies will be accepted as long as they are considered adequate for registration by Dr. Kurtin or his designate; the tumor must be cyclin D-1 positive by immunohistochemistry or have evidence of a t(11;14) translocation by fluorescence based in situ hybridization (FISH) or cytogenetics

* Splenic enlargement may be used as a measurable parameter if the spleen is palpable \>= 3 cm below the left costal margin
* Diffuse infiltration of an organ such as the stomach, bone marrow, peripheral blood, liver, lungs, or bowel by lymphoma without a discrete mass would constitute assessable, but not measurable, disease

* Serum total bilirubin (or direct bilirubin if total is abnormal) =\< institutional upper limit of normal (ULN) with or without secondary liver involvement
* Serum glutamic oxaloacetic transaminase (SGOT) =\< 3 x institutional ULN (exception: if there is liver involvement, SGOT must be =\< 5 x institutional ULN)
* Negative pregnancy test done =\< 7 days prior to registration, for women of childbearing potential only
* Willingness to return to NCCTG enrolling institution for follow-up
* Willingness to provide the blood specimens as required by the protocol
* Willingness to provide tissue specimens as required by the protocol
* Willing to return to NCCTG enrolling institution for follow-up
* Willing to provide blood and tissue specimens as required by the protocol
* Willing to abstain from eating grapefruit or drinking grapefruit juice
* Willingness to abstain from eating grapefruit or drinking grapefruit juice for the duration of the study
Exclusion Criteria
* Any prior therapy for mantle cell non-Hodgkin lymphoma including radiation therapy; exception: patient may have undergone a splenectomy for diagnosis, cytopenia, or systematic splenomegaly

* Medical or psychiatric conditions which, in the opinion of the investigator, make the patient a poor risk for participation
* Known to be human immunodeficiency virus (HIV) positive; HIV testing is not required but should be done if clinically indicated; HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study
* Concurrent malignancy =\< 5 years ago; exceptions: carcinoma in situ of the cervix, resected basal cell or squamous cell carcinomas of the skin, or prostate cancer that is in remission following a radical retropubic prostatectomy or radiation therapy; if there is a history of prior malignancy, they must not be receiving other specific treatment (other than hormonal therapy) for their cancer
* Known hypersensitivity to rituximab or its components, or to murine proteins
* Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm
* Prior treatment with an mTOR inhibitor
