  Purpose

Chemotherapy is the current standard treatment for unresectable recurrent cervical carcinoma after radiotherapy or distant metastasis of cervical carcinoma. The most effective regimens are cisplatin-based chemotherapy. After failure of the cisplatin-based chemotherapy, there is still no treatment that has been proved to be effective.

Human papilloma viruses (HPV) have been consistently implicated in causing cervical cancer especially those high-risk types (HPV 16,18,31,45) have been strongly associated with cervical cancer. HPV 16 was found in more than 50% of cervical cancer tissues. Results from many animal tumor models have indicated that immunization with tumor antigen-pulsed dendritic cells can trigger a long-lasting anti-tumor immune response and significantly inhibit the growth of implanted tumor cells. Recently, many clinical trials have been conducted to evaluate the feasibility and safety of immunizing cancer patients with tumor antigen-pulsed dendritic cells. No severe toxicity has been reported and some patients were shown to respond to the treatment. Based on previous animal and clinical studies by other investigators, we propose to evaluate the potential of immunizing cancer patients with antigen-pulsed autologous dendritic cells as a cancer vaccine to treat for recurrent cervical cancers after failure of cisplatin-based chemotherapy treatment or refusing chemotherapy. In this study, we will generate dendritic cells by culturing patient's autologous PBMC with GM-CSF and IL-4 in vitro. These dendritic cells will be pulsed with synthetic peptides representing the CTL epitopes on HPV Type 16 E7. Antigen-pulsed dendritic cells will be injected into inguinal lymph nodes under the guidance of real-time sonography. Each patient will receive four injections and 12 patients in total will be recruited for this study.
