Introduction/Objective. The goal of our research was to evaluate diagnostic
and prognostic role of positron emission tomography/computed tomography
(PET-CT) in patients previously treated for uterine cancer and compare it to
conventional imaging methods (CIM). Methods. We analyzed 37 patients
examined on PET-CT for follow-up or suspicion of uterine cancer recurrence,
and who were previously treated with surgery and/or chemoradiotherapy. All
patients underwent computed tomography or magnetic resonance imaging prior
to PET-CT, and were followed-up for at least one year. Results. PET-CT
showed sensitivity, specificity and diagnostic accuracy in uterine cancer
relapse detection of 96.3%, 70% and 89.2%, while those values for CIM were
92.6%, 40% and 78.4 %, respectively. Correlation of PET-CT and CIM findings
was 78% (29/37). In 13 out of 25 true positive patients on CIM, PET-CT found
greater number of active sites missed by conventional imaging. Positive
findings on PET-CT were associated with shorter progression free survival (p
= 0.023, logrank test). Conclusion. PET-CT constitutes an important
diagnostic method in management of recurrent cancer of uterine corpus,
demonstrating high sensitivity and accuracy. In comparison to CIM, PET-CT
can discover larger number of active tumor sites, and also shows better
specificity. PET-CT positive patients have worse prognosis with shorter
progression free survival.
