Radiological staging of ovarian cancer: imaging findings and contribution of CT and MRI.
Ovarian cancer is the most lethal among the gynecologic malignancies with approximately 70% of patients presenting with advanced tumor stage. The prognosis of patients with ovarian cancer is directly related to the tumor stage and residual tumor burden after cytoreductive surgery. Exploratory laparotomy has been the cornerstone in the management of ovarian cancer, as it offers staging and tumor debulking. Understaging at initial laparotomy, however, is a problem in up to 30%, mainly due to insufficient technique and unexpected peritoneal spread outside the pelvis. Sites difficult to assess intraoperatively including the posterior aspect of the liver and the dome of the diaphragm can be well demonstrated with multiplanar imaging. CT and alternatively MRI have been accepted as adjunct imaging modalities for preoperative staging ovarian cancer. Of these, multidetector CT is the imaging modality of choice for staging ovarian cancer. In a multidisciplinary team approach patient management may be guided towards an individualized treatment plan. The contribution of imaging includes (1) surgery planning including referral practice, (2) selection of candidates for primary chemotherapy by demonstration of non (optimally) resectable disease, and (3) tissue sampling in peritoneal carcinomatosis.
