Summary

RATIONALE: Vaccines, such as dendritic cell therapy (DC) made from a person's tumor cells and white blood cells may help the body build an effective immune response to kill tumor cells. Cryosurgery kills cancer cells by freezing them. Giving vaccine therapy together with cryosurgery may kill more tumor cells. PURPOSE: This clinical trial studies giving vaccine therapy together with or without cryosurgery in treating patients with B-cell Non-Hodgkin's lymphoma.

Detailed description

PRIMARY OBJECTIVES: I. Evaluation of safety and tolerability as measured by the incidence of significant toxicity of an autologous DC vaccine injection into a cryoablated tumor site (Arm A). II. Evaluation of safety and tolerability as measured by the incidence of significant toxicity of an autologous mature DC vaccine + tumor lysate generated in vitro and delivered intradermally (ID) (Arm B). SECONDARY OBJECTIVES: I. For cryoablation candidates: To assess feasibility, overall response rate, clinical benefit rate, time to response, and duration of response (Arm A). II. For patients receiving ID vaccine without cryoablation: To assess feasibility, clinical response rate, time to response, and duration of response (Arm B). TERTIARY OBJECTIVES: I. For cryoablation candidates: To assess the change over time in non-cryoablated nodes selected as the index lesions (Arm A). II. For patients receiving ID vaccine without cryoablation: To assess the change over time in measurable nodes selected as the index lesions (Arm B). III. To monitor patients' immune response after vaccine therapy. IV. Assess the immune response to Prevnar in cancer patients. V. Assess the effect of DC vaccination on presence of myeloid suppressors. VI. Assess the effect of tumor antigen delivery methods (in vivo DC into cryoablated tumor vs. ID injection of in vitro generated DC + lysate) on T cell response. OUTLINE: Patients are assigned to 1 of 2 treatment arms. In both arms, treatment continues in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 1 year, and then every 6 months for up to 2.5 years.
