title: Analysis of metastatic ovarian tumors from extragenital primary sites.
abstract: OBJECTIVE
  The aim of this study was to evaluate patients with metastatic ovarian tumors from extragenital primary sites.
  
  
  METHODS
  The medical records of 75 patients were reviewed retrospectively for age at diagnosis, presenting symptoms, preoperative tumor marker levels, preoperative diagnostic workup, operative technique, intraoperative evaluation, frozen-section and pathology results, laterality of metastasis, and primary tumor site. The specific impact of metastasis from colorectal and gastric primary sites on laterality, gross features and dimensions of ovarian mass, volume of ascites and tumor marker levels was investigated.
  
  
  RESULTS
  Primary sites were stomach (37.3%), colorectal region (28%), lymphoma (12%), breast (6.7%), biliary system (2.7%), appendix (1.3%) and small intestine (1.3%). It was not possible to identify the primary tumor site in 8 (10.7%) patients. Bilateral metastasis was found in 86.4% patients; 42.7% of the metastatic ovarian tumors were Krukenberg tumors; 50.7% of the ovarian masses were solid. Frozen section was confirmed by postoperative pathological results in 98% of the patients. The mean preoperative serum levels of tumor markers were 298.7 U/mL, 178 U/mL and 113.3 U/mL for CA 125, CA 19-9 and CA 15-3, respectively. CA 125 levels were above 35 U/mL in 81.3% of the patients. The presence of ascites was more frequent in ovarian tumors originating from colorectal and gastric primaries.
  
  
  CONCLUSIONS
  Surgery is essential for the diagnosis of the primary tumor and necessary for relief of symptoms. The identification of the primary site is required to plan adequate treatment.
