Chemoradiotherapy for cervical cancer.
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 has been tested. Recently, five randomised trials performed by the Gynecologic Oncology Group (GOG), Radiation Therapy Oncology Group (RTOG) and the SouthWest Oncology Group (SWOG) 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 two trials compared cisplatin-based concurrent chemotherapy and radiation to radiation with hydroxyurea. In all of the trials, cisplatin-based chemotherapy administered concurrently with radiation therapy was more effective at reducing the risk of death by 30-50%. Acute toxicities, principally neutropenia and gastrointestinal, were more common with chemoradiation, but were transient and the rates of late complications (complications that persisted or occurred for more than 60 days after the treatment) were similar. Based on the results of these five randomised trials, the National Cancer Institute (NCI) released a Clinical Announcement stating that cisplatin-based chemotherapy, as used in these trials (i.e. concurrently with radiation therapy), as the new standard of therapy for cervical cancer.
