All women managed for an epithelial ovarian cancer between 1 January 2000 and 30 June 2016 were included if they had a FDG PET CT, before initiation of any treatment (neoadjuvant chemotherapy or frontline cytoreductive surgery). The extent of disease on histology samples from cytoreductive surgery/observations during exploratory laparoscopy were compared with the PET CT results.
Over the study period, 980 women were managed for epithelial ovarian cancer, among them 90 (9.2%) had a PET CT before any treatment. The diagnostic reliability of an ovarian lesion was 67.8%, a colon lesion was 61.25%, a small intestine lesion was 50.6%, an epiploic lesion was 41.7%, a pelvic ganglionic invasion was 62.9% and a paraortic lymph node invasion was 61.5%. PET CT was less effective than a standard CT examination.
PET CT is not the most effective imaging examination to estimate the extent of peritoneal carcinomatosis during the initial management of an epithelial ovarian cancer.
