Objective: The aim of this study was to analyze clinical data such as diagnosis, surgical treatment and follow-up of patients with Krukenberg tumor (KT). We also reviewed literature of the subject.
Material and methods: We retrospectively analyzes medical data of 34 patients who were operated in Gynecology Clinic of Medical University of Gdansk in years 1999-2003. The definition of KT was that of Krukenberg's.
Results: The mean age of patients was 52, 23 of them were postmenopausal. Fourteen patients were diagnosed with malignant disease before surgery for ovarian tumor--11 were treated for breast cancer, 2 underwent resection of the stomach and one had rectosigmoidectomy. Before surgery a diagnosis for ovarian tumor such as ultrasonography, computer tomography and Ca125 were performed--in most cases sonography findings revealed mixed cystic and solid tumor of 320 cm in diameter; in 70% cases serum Ca125 was elevated with the highest result of 772 IU/ml. From among 20 patients who were suspected for primary ovarian cancer with no other malignant disease before surgery 9 had stomach cancer, 6 colon cancer, in 2 cases ovarian tumor was a metastasis from breast and in 1 from gall bladder; in 2 patients primary tumor was not found. The surgery performed in patients with KT was that of done for primary ovarian cancer. In 5 cased partial resection of colon was necessary. Surgical findings revealed ovarian tumor of 3-10 cm in diameter, solid and bilateral in most cases. The mean survival in our group was 4,7 months. The mean time between diagnosis of malignant disease and metastases to the ovary was 18 months. The best overall prognosis was for patients with breast cancer and the worst for cases with stomach cancer.
Conclusions: There is a poor prognosis for patients with Krukenberg tumor. The diagnosis is late, in most cases during surgery for ovarian tumor. The most often site of primary malignancy was breast and stomach.
