title: Adjuvant therapy for high-risk, early stage cervical cancer.
abstract: The identification of various pathologic risk factors after primary surgical management of early stage cervical cancer portends a higher rate of relapse and decreased survival. Historical attempts to improve outcome focused mainly on the use of adjuvant pelvic radiation, with limited success overall. Analysis of patterns of failure after radical hysterectomy led to better stratification of patients into risk groups and incorporated testing of systemic agents in those considered at high risk of distant failure. Two recently reported randomized, clinical trials have greatly advanced our understanding of the role of postoperative therapy in cervix cancer. In patients with positive nodes, the use of combined adjuvant chemotherapy and radiation significantly improves relapse-free survival and overall survival, compared with radiation alone. For node-negative patients with other primary tumor risk features, pelvic radiation significantly improves relapse-free survival, compared with no further therapy. An observed improvement in survival for irradiated patients awaits statistical confirmation after maturation of the data. Further improvements in adjuvant therapy for high risk, early stage cervical cancer will come from enhanced definition of prognostic variables, better patient selection, and refinements in both local and systemic therapies.
