This is a single-arm open-label pilot Phase II study. Following informed consent, eligible subjects will undergo excisional biopsy of a lymphoma-containing lymph node for diagnosis and for generation of the Oncoquest-L vaccine. Patients will receive subcutaneous injections consisting of their autologous tumor-derived Oncoquest-L vaccine starting at approximately 4 to 8 weeks after the biopsy. The first two doses will be given at a 2-week interval and the remaining 3 doses at monthly intervals. Patients will be monitored for response by performing imaging studies at baseline and 1 month after the fifth vaccination (Week 19). Additional imaging studies will be performed every 3 months for the first year and every 6 months during the second year until relapse or disease progression whichever occurs sooner.
