within 28 days prior to registration) OR aggregates or sheets of one of the
following:

- Measurable disease defined as a quantitative IgM monoclonal protein of ≥ 1000
mg/dL

immunohistochemistry or flow cytometry

- Lymph node biopsy must be done =< 28 days prior to registration if used as an
eligibility criterion for study entry

prior to registration

- In addition to measurable disease, patients must have symptomatic disease defined by
one or more of the following:

- Laboratory studies defining eligibility (Hgb, platelet count, viscosity) must
have been obtained within 28 days prior to registration; if more than one test
was obtained, the most recent one will be utilized

- Hemoglobin =< 11 g/dL

- Hyperviscosity syndrome or measured viscosity level of >= 4 centipoise

- NOTE: For these patients it is strongly recommended that they undergo
therapeutic plasmapheresis prior to initiation of therapy

- Platelet count < 100,000/MM^3

- Symptomatic lymphadenopathy, splenomegaly, or hepatomegaly

- Constitutional symptoms including fever, night sweats, or unexplained weight
loss (at least 10% of body weight in < 6 months)

- Additional requirements for Waldenstrom's macroglobulinemia (WM) patients (Phase I):

- Patients must have received previous treatment with at least one standard
regimen and are no longer responsive to that regimen

- If last regimen is with rituximab there must have been at least 6 months since
last rituximab dose, and if without rituximab there must have been at least 3
months since last regimen

- Additional requirements for WM patients (Phase II):

- For previously treated patients, no more than 4 prior regimens are allowed

- If last regimen is with rituximab there must have been at least 6 months since
last rituximab dose, and if without rituximab there must have been at least 3
months since last regimen

2.5 x institutional upper limit of normal (ULN), within 28 days prior to registration

- 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
cannot be enrolled if they do not meet these criteria on or off lipid lowering
medication; patients must start lipid lowering medication and cholesterol and
triglycerides must be below said levels before study entry

- Patients must not have had prior exposure to mammalian target of rapamycin (m-TOR)
inhibitors (sirolimus, temsirolimus, everolimus)

- Women must not be pregnant or breast-feeding due to the fact that the reproductive
risk to humans taking temsirolimus is unknown; all females of childbearing potential
must have a blood test or urine study within 2 weeks prior to registration 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)

- Women of childbearing potential and sexually active males must use an accepted and
effective method of contraception throughout the study and for 8 weeks following
discontinuation of everolimus

- Patients must have no history of prior malignancy except for adequately treated basal
cell or squamous cell skin cancer or in-situ cervical cancer; the patient may also
have had other cancer for which the patient was curatively treated with surgery alone
and from which the patient has been disease free for >= 5 years

- Platelets >= 75,000mm^3

- Serum creatinine =< 2.5 mg/dL

- Patients must be tested for hepatitis B surface antigen (HBsAg) and hepatitis B core
antibody (anti-HBc) within 28 days of registration and will not be eligible if found
to be positive

- Patients must not have any severe and/or uncontrolled medical condition or other
conditions that could affect their participation in the study, including, but not
restricted to:

- Symptomatic congestive heart failure of New York Heart Association class III or
IV

- Unstable angina pectoris, symptomatic congestive heart failure, myocardial
infarction within 3 months of start of study treatment, serious uncontrolled
cardiac arrhythmia or any other clinically significant heart disease
