This is a phase I clinical trial of cytotoxic T cell injection induced by dendritic cells loaded with 6B11 anti-idiotype minibody (6b11-OCIK injection) for recurrent drug-resistant ovarian cancer. Main purpose of this research is to determine the maximum tolerable dose (MTD) of 6B11-OCIK injection in the treatment of patients with ovarian cancer. Moreover, secondary purpose is to evaluate the effect of 6B11-OCIK injection on the immune system of patients, the efficacy of autologous 6B11-OCIK injection in the treatment of patients with ovarian cancer obtain and the correlation between OC166-9 antigen expression and efficacy of 6B11-OCIK injection. Thirdly, exploratory purpose is to evaluate the effect of 6B11-OCIK injection on laboratory examination.
