Epidemiology and prognosis of ovarian metastases in colorectal cancer.
Summary of "Epidemiology and prognosis of ovarian metastases in colorectal cancer."
BACKGROUND:
: National guidelines for prophylactic oophorectomy in women with colorectal cancer are lacking. The aim of this population-based cohort study was to report on the prevalence, incidence and prognosis of ovarian metastases from colorectal cancer, providing information relevant to the discussion of prophylactic oophorectomy.
METHODS:
: All 4566 women with colorectal cancer in Stockholm County during 1995-2006 were included and followed until 2008. Prospectively collected data regarding clinical characteristics, treatment and outcome were obtained from the Regional Quality Registry.
RESULTS:
: The prevalence of ovarian metastases at the time of diagnosis of colorectal cancer was 1.1 per cent (34 of 3172) among women with colonic cancer and 0.6 per cent (8 of 1394) among those with rectal cancer (P = 0.105). After radical resection of stage I-III colorectal cancer, metachronous ovarian metastases were found during follow-up in 1.1 per cent (22 of 1971) with colonic cancer and 0.1 per cent (1 of 881) with rectal cancer (P = 0.006). Survival in patients with ovarian metastases was poor.
CONCLUSION:
: Ovarian metastases from colorectal cancer are uncommon. Copyright (c) 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

Medical and Biotech [MESH] Definitions
Colorectal Neoplasms
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Genes, Mcc
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
Genes, Dcc
Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
Colorectal Neoplasms, Hereditary Nonpolyposis
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Hemibody Irradiation
Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (UHBI) or lower hemibody irradiation (LHBI). Less common is mid-body irradiation (MBI). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with WHOLE-BODY IRRADIATION. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (P. Rubin et al. Cancer, Vol 55, p2210, 1985)
