Outline of Final Research Achievements

We performed a phase II clinical trial of HLA-A24 and A2 restrictive Glypican-3 (GPC3) peptide vaccine for 92 ovarian clear cell carcinoma patients as one of the immunotherapy for refractory ovarian carcinoma. We confirmed three partial responses in a advanced patient. However our resuths showed that the patients with peritoneal dissemination had slightly effectiveness of peptide vaccine. We investigated the interaction between ovarian clear cell carcinoma cells and peritoneal cells. We showed that the expressions of VEGF, IL-6 and IL-8 elevated and the functions of CD8 possitive T cells (CTL) were decreased. Our results showed that peritoneal dissemination of ovarian carcinoma was immunosuppresive environment.
