LS1081, "A Pilot Study of Dendritic Cell Therapy Delivered Intratumorally After Cryoablation or Intradermally for Patients With B-Cell Non-Hodgkin's Lymphoma"

Inclusion Criteria:

- Histological confirmation of biopsy-proven B-cell non-Hodgkin's lymphoma, excluding
chronic lymphocytic leukemia, primary CNS lymphoma and Burkitt's lymphoma.

- Patient must have at least 2 measurable lesions that are >= 1.5cm in one dimension.
One of the lesions, must meet additional criteria a or b depending on the treatment
arm. a) For Arm A, patient must have at least one lesion that is >= 2.0cm and is
amenable to image-guided cryoablation and multiple vaccine injections as determined
by Interventional Radiology (including tumors that can be safely accessed using
imaging guidance and treated with minimal risk to adjacent structures). b) For Arm B,
patient must have one lesion that can be excised for in vitro vaccine preparation.

- ECOG Performance Status (PS) 0, 1, 2

- Absolute neutrophil count > 1000/uL

- Absolute lymphocyte count > 500/uL

- PLT >= 100,000/uL

- HgB >= 8.0 g/dL

- Total bilirubin =< 1.5 x upper limit of normal (ULN) or if total bilirubin is > 1.5 x
ULN, the direct bilirubin must be normal

- Negative serum pregnancy test done =< 7 days prior to registration, for women of
childbearing potential only

- Provide informed written consent

- Willingness to return to a Lymphoma SPORE enrolling institution for follow-up

- Patient willing to provide tissue and blood samples for research purposes

Exclusion Criteria:

- Pregnant women

- Nursing women

- 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
toxicity of the prescribed regimens

- Patients known to be HIV positive

- Serious non-malignant disease such as active infection, symptomatic congestive heart
failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social
situations or other conditions which in the opinion of the investigator would
compromise protocol objectives

- Receiving any other investigational agent considered as a treatment for the primary
neoplasm

- History of other primary malignancy requiring systemic treatment within 6 months of
protocol enrollment

- Patients must not have another active malignancy requiring treatment

- Patients must not be receiving chemotherapy or immunotherapy for another cancer

- Prior allogeneic bone marrow or peripheral blood stem cell transplantation

- Prior autologous bone marrow or peripheral blood stem cell support within 1 year

- Major surgery other than diagnostic surgery =< 4 weeks

- History of hypersensitivity and anaphylactoid reactions to pneumococcal vaccine or
any component of the formulation, including diphtheria toxoid

- Active autoimmune disease such as Crohn's disease, rheumatoid arthritis, Sjogrens'
disease, systemic lupus erythematosis, or similar conditions

- Coagulopathy, including the use of Coumadin or heparin anticoagulants that cannot be
discontinued for the cryoablation procedure (NOTE: Heparin for line patency without
detectable lab abnormalities for coagulation will be allowed)

- Patients must be off corticosteroids for at least 2 weeks prior to registration (this
includes oral, IV, subcutaneous, or inhaled route of administration); patients on
chronic corticosteroid for adrenal insufficiency or other reasons may enroll if they
receive less than 10 mg/day of prednisone (or equivalent)

- Patients with active CNS malignancy are not eligible for this trial
