Abstract

Radiation was until recently the key and only modality for the routine treatment of locally advanced cervical carcinoma. However after years of studying multi-modality treatments as an alternative to radiation alone in randomized phase III trials, the standard treatment has changed to chemo-radiation based on cisplatin. Three recent meta-analyses have confirmed that cisplatin-based chemo-radiation adds an absolute 12% benefit in five-year survival over radiation therapy alone. Neoadjuvant chemotherapy followed by radiation has not been of proven benefit, but when neoadjuvant chemotherapy is followed by surgery, an absolute increase of 15% in five-year survival over radiation alone is seen. This benefit in survival is comparable to that obtained with the current chemo-radiation schedules based on cisplatin. Despite these encouraging results there remains room for improvement as the five-year survival of patients treated with chemo-radiation ranges from nearly 80% in bulky IB tumours to only 25% in stage IVA disease. Other therapeutic approaches need to be fully evaluated including the use of chemo-radiation after neoadjuvant chemotherapy; the use of new drug combinations and the multi-modality combination of neoadjuvant chemotherapy followed by radical surgery plus adjuvant chemo-radiation. Likewise, the addition of radiosensitizers to cisplatin, preoperative chemo-radiation and/or adjuvant chemotherapy may eventually improve the currents results of cisplatin-based chemo-radiation. Nevertheless, it is hard to foresee a dramatic increase in cure rate, even with the most optimal combination of cytotoxic drugs, surgery and radiation, and thus the testing of molecular targeted therapies against cervical cancer is a logical step to follow.
