Radiotherapy With Single-Agent Cisplatin or Combination Chemotherapy in Defined Poor-Prognostic Cervical Cancer

Concurrent radiotherapy with cisplatin-based chemotherapy has become the standard treatment for patients with cervical cancer. However, in patients with advanced cervical cancer, half of them treated with contemporary radiotherapy plus single agent cisplatin still suffered from the local or distant relapse. How to improve the treatment outcome of these patients is a very important issue and requires further clinical investigation. The major aim of this project is to conduct a prospective, randomized phase III clinical trial to examine if cervical cancer patients treated by radiotherapy with cisplatin and gemcitabine have better survival rates than those treated by radiotherapy with cisplatin alone. Gemcitabine has been demonstrated to be a good radiosensitizer. In keeping with this, few clinical trials in early phases showed promising results when using concurrent radiotherapy with cisplatin and gemcitabine. According to these positive results, the investigators expect this trial has the potential to improve the survival in patients with advanced cervical cancer, reduce the medical costs due to tumor relapse, and then benefit the whole society.
