Our goal is to enroll 10 patients over a 1-2 year time period with intact cervical cancer (Stage IB-IVA) who will receive definitive radiation therapy at Emory University Hospital and Emory Crawford Long Hospital. Two Calypso beacons will be attached within a cervical "Smit" sleeve [1 superior, 1 inferior] which will be placed within the cervical os prior to CT simulation (radiation planning session). The cervical sleeve will be sutured in with 2 stitches. The location of the transponders will be tracked throughout the treatment delivery. Daily cone beam CT on the radiation treatment machine will also be utilized to confirm transponder placement and evaluate tumor volume changes during the treatment course. There will be no treatment field modifications based on cervical (transponder) displacement. While enrolled on this study, patients will be treated with the current standard of care treatment: 5 weeks of external beam radiation with concurrent weekly cisplatin and followed a focal radiation "boost" using intracavitary brachytherapy. The 5 weeks of external beam radiation therapy will be delivered with a conventional 4-field technique to the whole pelvis for a total of 45Gy at 1.8 Gy per fraction. All external beam radiation treatments will be delivered at the Emory Clinic, Clifton Road. The cervical sleeve will be removed following the external beam portion of therapy.
