Abstract

Cervical cancer remains a major health problem worldwide, despite advances in screening. For patients with locally advanced stage disease, failure to obtain local-regional control usually results in death. In an effort to improve local-regional tumour control, neoadjuvant and concurrent chemoradiation have been tested. Recently, 5 randomised trials performed by the Gynecologic Oncology Group, Radiation Therapy Oncology Group and the Southwest Oncology Group studying cisplatin-based chemoradiation have demonstrated a significant survival advantage. Three of the trials compared cisplatin-based concurrent chemotherapy and radiation to radiation alone and 2 trials compared cisplatin-based concurrent chemotherapy and radiation to radiation with hydroxyurea. In all trials, cisplatin-based chemotherapy administered concurrently with radiation therapy was the more effective therapy, reducing the risk of death by 30 to 50%. Acute toxicities, principally neutropenia and gastrointestinal, were more common with chemoradiation but were transient and rates of late complications were similar between treatment groups. Based on the results of these 5 randomised trials, the National Cancer Institute released a Clinical Announcement stating that cisplatin-based chemotherapy as used in these trials concurrently with radiation therapy should be the new standard of therapy for high risk early stage and locally advanced stage cervical cancer.
