title: [Evidence based of chemoradiotherapy in cervix carcinoma].
abstract: Since 10 years, the combination of chemoradiotherapy has become a standard of treatment of the advanced localized cervical cancer. Two systematic reviews of the literature (including the results of the different clinical trials) have already been published. The aim of this article is to present the results of the recent meta-analysis based on individual patient data and to discuss the perspectives. This meta-analysis was rigorously designed: trials selected had the same control arm with the same radiotherapy without concomitant chemotherapy, the definition of the primary outcome (overall survival) was homogeneous and analysis was made in intent to treat. The results confirm the advantage in overall survival in favor of the chemoradiotherapy with an absolute 5-year overall survival benefit of 6% (60-66%) and 8% of 5-year disease-free survival (50-58%). Interestingly, even if cisplatin seems to be the most active drug, a significant advantage is also observed with no platinum chemotherapy. A polychemotherapy is not more active than a monochemotherapy and there was a suggestion of a difference in the size of the survival benefit with tumor stage. Larger benefits were seen for the few trials in which additional chemotherapy was administered after chemoradiotherapy, but results have to be confirmed by other clinical trials. Late toxicity was not well evaluated and a long-term follow-up of the patients is important to assess the real incidence of long-term side effects of the chemoradiotherapy and the impact on quality of life. New strategies combining new chemotherapy protocols or targeted therapy with radiation are promising but have to be evaluated in comparative clinical trials before use in routine.
