Chemoradiation in cervical carcinoma: a must?

Abstract

Cervical carcinoma is one of the most frequent gynecological malignancies. Literature shows that while the rate is exceedingly low in systematically screened populations, the incidence remains high because of large populations of at-risk women--particularly in underserved nations and in medically indigent subpopulations of Western nations--who are not screened. Recently, a series of randomized trials has demonstrated the possibility to dramatically improve the prognosis of these patients by using concurrent chemoradiation. In particular, concurrent chemoradiation represents a major treatment option in patients with bulky IB-IIA disease, IIB-IVA disease and resected IB-IIA disease with poor prognostic factors. However, further studies are necessary to optimize treatment schedules and particularly to define the best drug combination to be used during radiation therapy, improve patients selection by the analysis of anatomical (TNM stage) and non-anatomical (tumor oxygenation, genetic markers, tumor angiogenesis) prognostic factors, explore novel treatment strategies, such as use of neoadjuvant chemoradiation in locally advanced tumors, integration of antiangiogenetic therapies in chemoradiation schedules, use of supportive treatments aimed to overcome tumor hypoxia, to evaluate the possibility of 'cure' of locally recurrent tumors by chemoradiation and finally to define the best 'second-line' treatment for patients failing after chemoradiation with or without surgery.
