For most cervical cancers, radiotherapy is the mainstay of treatment. The introduction of concurrent chemotherapy to radiation at the end of the 20th century led to a significant improvement in disease survival. Now, techniques such as intensity-modulated radiotherapy, which allow a high degree of conformity to the tumor, offer the opportunity to further improve outcome by reducing treatment-related toxicity and also to potentially improve local control by an increase in tumor dose. This review will outline the history and current state of play of cervical radiotherapy.
