The limitations of overall treatment time and the maximal dose of RT that can be safely delivered to the pelvis targets make cervical carcinoma a tumor in which Tomotherapy can potentially improve the therapeutic ratio. Tomotherapy's ability to deliver more conformal RT to target structures and minimize dose to normal structures may allow for delivery of altered fractionation radiation plans for cervix cancer with acceptable rates of RT-related toxicities. Tomotherapy allows for delivery of differential daily doses of RT to target volumes that lie within larger target volumes which in effect delivers a simultaneous integrated boost (SIB) to areas of gross disease which lie within a larger volume at risk for harbouring micrometastases. Delivery of the boost dose of radiation in a simultaneous as opposed to sequential fashion decreases the overall RT treatment time which theoretically reduces the effects of accelerated tumor cell repopulation. Delivering higher doses per fraction to areas of gross disease would theoretically increase the radiobiologic enhancement effects of concurrent cisplatin chemotherapy.
