Cervix Regression and Motion During the Course of External Beam Chemoradiation for Cervical Cancer

To evaluate the magnitude of cervix regression and motion during external beam chemoradiation for cervical cancer.Sixteen patients with cervical cancer underwent computed tomography scanning before, weekly during, and after conventional chemoradiation. Cervix volumes were calculated to determine the extent of cervix regression. Changes in the center of mass and perimeter of the cervix between scans were used to determine the magnitude of cervix...
