Krukenberg tumors: can management be improved?
OBJECTIVE
The Montefiore Medical Center experience with women with gastrointestinal (GI) cancer was reviewed to: (1) evaluate clinical parameters in patients with Krukenberg tumor (GI cancer metastatic to the ovaries) and (2) evaluate oophorectomy in GI cancer patients.


METHODS
(1) Charts of all female patients admitted between 1985 and 1996 with gastric or colon cancer were reviewed.


RESULTS
The frequency of Krukenberg tumor was 7/1,021 (0.7%). The median age at presentation was 39.5 years (range 35-80); 5 were premenopausal, 2 of whom were postpartum. Krukenberg tumor was significantly more common in the premenopausal patients with gastric cancer (p = 0.002), colon cancer (p = 0.001), and in both sites combined (p < 0.001). Our rate of pregnancy-associated Krukenberg tumors (28.6%) was significantly higher (p < 0.05) than that found in 4 of 5 large studies. The average survival of our 7 patients was 12.3 months (range 4 days to 26 months), with secondary debulking and chemotherapy offering 1 patient the longest longevity. Only 19/788 (2.4%) women had oophorectomy during their colon cancer surgery revealing 2 (10.5%) Krukenberg tumors, 6 (31.6%) benign solid or cystic ovarian tumors, and 11 (57.9%) normal or atrophic ovaries.


CONCLUSIONS
Krukenberg tumors are rare. There is no uniformity of data reported in the literature. Krukenberg tumors were more common in premenopausal women with gastric or colon cancer compared to postmenopausal women. Our rate of pregnancy-associated Krukenberg tumors appeared to be higher compared to other studies. Prophylactic oophorectomy in pre- and postmenopausal women should be considered at the time of GI cancer surgery, and requires further study. A national registry combined with prospective, multisite studies are needed to gather data and evaluate treatment.
