| Research Abstract |
HLA-A24 or HLA-A2 positive 17 patients with recurrent colorectal cancers were accepted cancer vaccine therapy. All the patients was ineffective at chemotherapy. First, we had checked skin test and CTL precursor frequency of patient for our cancer peptide vaccines. Then, each patient had been tried 3mg of three or four most frequent cancer vaccines intradermaly three times bi-weekly, and at the fourth trial, cancer peptide vaccines and intravenous 5FU(750mg) and Leucovorin(250mg) combined therapy had been star every other weeks. We have been investigated CTL precursor frequency all the period. CTL precursor frequencies were increased in all the patients. At seven of 14 patients, Ig G antibodies for cancer peptide vaccines were increased. And there were no severe adverse effects. Tumor markers (CEA) and tumor sizes were decreased and alive more than ten months. Two ware survived more than 1 year and two ware survived more than 2 years. We think our combined cancer vaccine and chemotherapy, intravenous 5FU(750mg) and Leucovorin(250mg), may be effective for patients with recurrent colorectal cancers after sugery.
