SUAREZ FERNANDEZ, J. P. et al. Aportación de la Tomografía por Emisión de Positrones (PET) al manejo de los tumores malignos de ovario y útero. Oncología (Barc.) [online]. 2005, vol.28, n.5, pp.12-25. ISSN 0378-4835.

Positron Emission Tomography (PET) has a limited value in both detecting and staging ovarian cancer, although it can provide aditional information to conventional imaging. PET cannot replace the "second-look" surgical procedures because it frequently misses micronodular disease. Nevertheless, PET imaging shows a high accuracy for detecting recurrent or residual disease, so it should be recommended as the diagnostic technique of choice in these situations. The new PET-CT hybrid cameras will increase diagnostic accuracy and will probably replace dedicated PET scanners. PET is a useful non-invasive method to assess the stage of cervical cancer prior to therapy, and may help to plan surgery or irradiation. Follow-up with PET studies allows to an early and accurate diagnosis of residual or recurrent disease with better results than conventional imaging. It can also provide useful data to predict prognosis and monitorize treatment response, in order to identify high-risk patients who will receive more aggressive therapies. Further investigations are needed to assess the value of PET in the cancer of the uterine body.
