Diagnosis of recurrent uterine cervical cancer: computed tomography versus positron emission tomography.
OBJECTIVE
To determine the accuracy of CT and positron emission tomography (PET) in the diagnosis of recurrent uterine cervical cancer.


METHODS
Imaging findings of CT and PET in 36 patients (mean age, 53 years) in whom recurrent uterine cervical cancer was suspected were analyzed retrospectively. Between October 1997 and May 1998, they had undergone surgery and/or radiation therapy. Tumor recurrence was confirmed by pathologic examination or follow-up studies.


RESULTS
In detecting recurrent uterine cervical cancer, the sensitivity, specificity, and accuracy of CT were 77.8%, 83.3%, and 80.5%, respectively, while for PET, the corresponding figures were 100%, 94.4%, and 97.2%. The Chi-square test revealed no significant difference in specificity (p =.2888), but significant differences in sensitivity (p =.0339) and accuracy (p =.0244).


CONCLUSIONS
PET proved to be a reliable screening method for detecting recurrent uterine cervical cancer, but to determine the anatomical localization of recurrent tumors, and thus decide an adequate treatment plan, CT was eventually needed.
