Background: Metastatic malignancy occurs rarely in the colon or rectum. We presented 14 patients with colorectal metastasis (CRM). Methods: A retrospective review was conducted on a computerized colorectal tumor database at the Taipei Veterans General Hospital from January 2000 to June 2013. Results: The incidence of CRM was 0.19% (14 in 7,524 patients). There were 6 males and 8 females with a mean age of 66.9 ± 13.6 years. Origins of the CRM included lung cancers (n = 3), prostate cancers (n = 2), and others (n = 1, respectively). Clinical presentations were not specific and colonoscopic pictures were indistinguishable from primary colorectal cancers; 5 of the 9 biopsies identified metastasis. Eight patients had extracolonic metastasis and 6 patients had CRM only. Significantly better survival was observed in the CRM-only group (p = 0.037). The mean interval from the treatment of primary tumor to the diagnosis of CRM was 30.2 ± 49.0 months. The mean survival time after CRM was 24.9 ± 30.8 months. Conclusion: Clinical features and colonoscopic findings of CRM were indistinguishable from primary colorectal cancer. Histopathological review of the biopsy could be helpful in identifying the primary lesion. Surgical resection with curative intent provided longer survival in CRM-only patients.
