PET/CT and RT in Ovarian cancer

28 PET/CT-IMRT 30 CT-IMRT

58 pts with recurrent ovarian cancer

Changes in GTV (PETvsCT) delineation in 10 pts (35.7%) inclusion of metastatic LN and distant mts . Tumor response : 64.3% vs. 46.7% 3-year overall survival : 34.1% vs. 13.2

PET/CT guided IMRT in recurrent ovarian cancer patients improve the delineation of GTV and reduce the likelihood of geographic misses and therefore improve the clinical outcome.
