OBJECTIVES: Colorectal cancer (CRC) screening by fecal occult blood testing and flexible sigmoidoscopy is recommended by many authorities for those older than age 50. Ashkenazi Jews have been shown to have a higher level of CRC and polyps than the general population. A subset of Ashkenazi Jews, Russian-speaking Jewish immigrants to the United States (RJIs), have not been studied extensively for CRC and may have additional risk factors not found in other Ashkenazi populations. METHODS: A retrospective chart review was undertaken of fecal occult blood tests, endoscopy reports, and pathology reports of 132 RJIs and 124 non-RJI controls over age 50 between 1987 and 1999 at the Jewish Hospital of Cincinnati Medical Outpatient Clinic. RESULTS: Mean ages at the time of diagnosis or flexible sigmoidoscopy were 68 yr for RJIs and 66 yr for the non-RJI patients. Of the RJI patients, 38.7% had positive findings: 37 (28.0%) with lesions < 2 cm, five (3.8%) with lesions > 2 cm, and nine (6.8%) with CRC. Of the non-RJI control group patients, 16.9% had positive findings: 16 (12.9%) with lesions < 2 cm, three (2.4%) with lesions > 2 cm, and two (1.6%) with CRC. Age- and sex-matched statistical analysis revealed significantly greater CRC and significantly more polyps > 2 cm for the RJI patients (p < 0.003). This is higher than in other studies of Ashkenazis, which show a 2.3% incidence, and in statistics from the National Cancer Institute, which reveal a national CRC incidence rate for those over age 65 to be 0.30%. CONCLUSIONS: RJIs in our study have polyps > 2 cm and CRC at a rate of 10.6%, as compared with 4.0% for in-clinic controls and a national average of 0.30% for patients over age 65. This suggests a need for more aggressive screening of this patient population for CRC.
