Ovarian metastases from colorectal cancer: a clinicopathological analysis of 103 patients.
OBJECTIVE
To improve management of ovarian metastasis through assessment of clinicopathological features and treatment outcomes associated with ovarian metastasis from colorectal cancer.


METHODS
We recruited 103 subjects who were diagnosed with ovarian metastasis and subjected to surgery between June 1989 and December 2005. Clinical and pathological variables were evaluated. Survival and its associated factors were analysed with a median follow-up of 31 months after ovarian surgery (range 1-129 months).


RESULTS
The mean age at diagnosis was 46 years (range 14-72 years), synchronous ovarian metastasis occurred in 74 patients and metachronous in 29 patients. The primary tumour was more commonly associated with the colon rather than the rectum (84/1608, 5.2%vs 19/1534, 1.2%, P < 0.001). Combined metastases occurred in 69 patients (67%). Complete resection was achieved in 34 (33%) patients without other metastases. The estimated 5-year disease free survival and overall survival rate were 40.1% and 26.6%, respectively. From univariate analysis, lymphovascular invasion (35.6%vs 12.8%, P = 0.034), combined metastasis (50.9%vs 15.6%, P = 0.0035) and bilaterale ovarian metastasis (36.4%vs 10.6%, P = 0.015) were identified as significant poor prognosis factors, and from multivariate analysis combined metastasis and bilaterale ovarian metastasis were significant (P = 0.034 and P = 0.015, respectively).


CONCLUSIONS
This study suggests a role for regular follow-up computed tomography scans within 6 months postoperatively and tumour marker assays for the early detection of ovarian metastasis in premenopausal women after primary surgery, especially in colonic patients with poor prognostic factors.
