Brief summary
The purpuse of this study is to assess toxicities of angiogenic peptide vaccine therapy with gemcitabine in treating HLA-A\*0201 restricted patient with non-resectable pancreatic cancer.
Detailed description
The prognosis of pancreatic cancer is extremely poor even with extensive surgery, chemotherapy or radiation. It has been required development of new treatment modalities. Immunotherapy is one of the encouraging modalities for cancer patients. The investigators have to assess its toxicities and immune responsiveness.
Interventions
One mg of each peptide will be administered subctaneously on days 1, 8, 15 and 22
Gemcitabine will be administered intravenously at a fixed dose of 1000mg/m2 on day 1, 8, 15.
