The main outcomes of the study was success and complication rates. Table 1 EUS-guided intra-arterial chemotherapy appears to be safe feasible in a subset of patients with metastatic liver disease. Further studies are necessary before a formal recommendation is made. Table 1.

“EUS guided intratumoral therapy is a promising development in the treatment of pancreatic cancer. Intratumoral vaccination

is an emerging strategy for immunotherapy of tumors. Our laboratory was the first to demonstrate effective treatment of murine solid tumor models with intratumoral poxvirus vaccine. The recombinant pox viral vaccine “Panvac” encodes tumor antigens CEA and Muc-1 and 3 immune co-stimulatory antigens B7, LFA-3 and ICAM1. Intradermal and subcutaneous administration of this vaccine was previously studied for treatment of colorectal and pancreatic cancer. We present here, a human phase I trial of EUS guided intratumoral, and systemic administratation of Panvac for treatment of patients with locally advanced inoperable CYTH4 pancreatic adenocarcinoma. Thirteen patients

were enrolled at 2 dose levels of the intrapancreatic vaccine, Panvac-F (Fowlpox encoding MUC-1, CEA, TRICOM). Dose level 1 was 108 plaque-forming units (PFU); dose level 2 was 109 PFU. Systemic therapy consisted of subcutaneous Panvac-V (vaccinia, 2 X 108 PFU) and subcutaneous Panvac-F. Patients received a total of 2 EUS guided fine needle injections (EUS-FNI) given 2 weeks apart, 1 subcutaneous Panvac-V and 4 subcutaneous Panvac-F boosts given with GMCSF, extending to day 71. Patients were allowed to transition to standard care at day 35. EUS-FNI was performed with a standard 22 or 25 gauge needle. Procedural complications, toxicity, tumor progression, serum CA 19-9 and CEA levels were monitored. In the lower dose cohort, 2 out of 7 patients were removed from study after two weeks due to rapid disease progression locally, and died two and six months after trial initiation. One patient had mild pancreatitis that resolved allowing completion of protocol therapy. Two patients are alive at 15 and 30 months into follow up.
