TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['To study the anti-tumor immunotherapeutic effect induced by the suicidalcancer vaccine FC/TK, and to evaluate the safety of this vaccine.', 'The suicidal cancer vaccine, named FC/TK, was prepared by fusion of suicide gene (HSVI,-TK gene) -modified ovarian carcinoma NuTu-19 cells with rat bone marrow-derived dendritic cells (DCs). The morphology of FC/TK was evaluated by scanning electron microscopy. The stimulatory effect of FC/TK on T cells was determined by T cell proliferation assay. In immunotherapeutic studies in vivo, Fischer344 rats were injected subcutaneously with NuTu-19 cells, followed by treatment of FC/TK on days 7 and 14, compared to controls treated with irradiated FC/TK, FC or PBS, respectively. Tumor incidence and volume were measured in 90 days after challenge. To determine the killing effect of FC/TK in vivo, TUNEL assays were applied to detect apoptotic cell death in spleen of vaccinated rats with prodrug ganciclovir administration.', 'FC/TK cells were of irregular shape with surface membrane processes. Compared to the control groups, FC/TK significantly promoted T cell proliferation (P <0.01). The rats vaccinated with FC/TK and FC significantly inhibited the tumor growth compared to rats vaccinated with irradiated FC/TK (P <0.05) or with PBS ( P <0.01). The immunotherapeutic effect induced by FC/TK was similar to that using FC. Fluorescence microscopy showed that fluorescein-stained FC/TK cells migrated into spleen also showed to be TUNEL-positive, suggesting that the FC/TK cells were killed by ganciclovir in vivo.'] Does [ Suicidal cancer vaccine enhance anti-tumor immunotherapeutic effect and its safety in the treatment of ovarian cancer ]?
