Summary in tumor size of pre- and post-fixation, retraction ratio of corresponding area and volume, and actual pathologic volume of ten cervical cancers.

Abbreviations: Dlong = long diameter on transverse plane before formalin fixation; Dshort = short diameter on transverse plane before formalin fixation; dlong = long diameter on transverse plane after formalin fixation; dshort = short diameter on transverse plane after formalin fixation; Area retraction = tumor transverse plane reduction after formalin fixation, which is calculated according to the formula (dlong× dshort)/(Dlong×Dshort); Volume retraction = tumor volumetric retraction after fixation, which equals (area retraction); GTVpath = pathologic tumor volume.
