Colorectal cancer in Russian-speaking Jewish emigrés: community-based screening.
OBJECTIVE
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.
