Rituximab, Cyclophosphamide, Bortezomib, and Dexamethasone in Treating Patients With Relapsed or Refractory Low-Grade Follicular Lymphoma, Waldenstrom Macroglobulinemia, or Mantle Cell Lymphoma

Inclusion Criteria:

* Histological confirmation of relapsed or refractory follicular Grades 1 or 2 lymphoma, mantle cell lymphoma (MCL), small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL), extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) type, nodal marginal zone B-cell lymphoma, splenic marginal zone B-cell lymphoma, or lymphoplasmacytic lymphoma (Waldenstrom's macroglobulinemia/WM) by biopsy ≤ 6 months prior to registration

  * NOTE: MCL diagnosis should be confirmed by cyclin D1 staining or fluorescence in situ hybridization (FISH) (t(11;14))
* Measurable disease by computed tomography (CT), positron emission tomography (PET)/CT or magnetic resonance imaging (MRI) scans with lymph nodes ≥2.0 cm in at least one dimension or tumor cells in the blood ≥ 5 x10\^9/L

  * NOTE: Lymphoplasmacytic lymphoma (WM) patients without lymphadenopathy must have 1.) \>10% lymphocytes, lymphoplasmacytic cells or plasma cells on a bone marrow aspirate/biopsy, and 2.) quantitative IgM ≥ 400mg/dL
* Expected survival \> 3 months
* ECOG Performance Status (PS) 0, 1 or 2
* Absolute Neutrophil Count ≥ 1200
* Platelet ≥ 75000
* Hemoglobin ≥ 8.0 g/dL
* Total bilirubin ≤ 1.5 x upper limit of normal (ULN)
* Alkaline phosphatase ≤ 3 x ULN
* Aspartate aminotransferase (AST) ≤ 3 x ULN
* Creatinine ≤ 1.5 x ULN
* Female subject is either postmenopausal for at least 1 year before the screening visit, is surgically sterilized or if they are of childbearing potential, agree to practice 2 effective methods of contraception from the time of signing the informed consent form through 30 days after the last dose of VELCADE (bortezomib), or agree to completely abstain from heterosexual intercourse
* Male subjects, even if surgically sterilized (i.e., status postvasectomy) must agree to 1 of the following: practice effective barrier contraception during the entire study treatment period and through a minimum of 30 days after the last dose of study drug, or completely abstain from heterosexual intercourse
* Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care
* Willingness to return to Mayo Clinic institution for follow-up
* Negative serum pregnancy test done \<7 days prior to registration, for women of childbearing potential only
* Willingness to complete questionnaires by themselves or with assistance

Exclusion Criteria:

* Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:

  * Pregnant women -- confirmation that the subject is not pregnant must be established by a negative serum B-human chorionic gonadotropin (B-hCG) pregnancy test result obtained during screening. Pregnancy testing is not required for post-menopausal or surgically sterilized women;
  * Nursing women;
  * Men or women of childbearing potential who are unwilling to employ adequate contraception
* Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and adverse event of the prescribed regimen
* Patients known to be human immunodeficiency virus (HIV) positive
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
* Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm
* Diagnosed or treated for another malignancy ≤ 3 years prior to registration, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy or low-risk prostate cancer after curative therapy

  * NOTE: If there is a history of prior malignancy, they must not be receiving other specific treatment (other than hormonal therapy) for their cancer
* Patient has received other investigational drugs ≤ 14 days prior to registration
* Patient has hypersensitivity to bortezomib, boron or mannitol
* Myocardial infarction ≤ 6 months prior to registration or has New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities

  * NOTE: Prior to study entry, any electrocardiogram (ECG) abnormality at Screening has to be documented by the investigator as not medically relevant
* Previous cancer therapy, hormonal therapy and surgery \< 4 weeks prior to registration
* Patient has ≥ Grade 2 peripheral neuropathy
* Radiation therapy within 3 weeks before randomization

  * Enrollment of subjects who require concurrent radiotherapy (which must be localized in its field size) should be deferred until the radiotherapy is completed and 3 weeks have elapsed since the last date of therapy
