    Abstract:
    A study of 191 screenees at high risk for colorectal neoplasm was undertaken to evaluate the value of the leukocyte adherence inhibition (LAI) test in detecting colorectal neoplasms. All screenees underwent total colonoscopy and LAI test. Results show that 94/191 (49.2%) screenees had neoplasms. Overall LAI positivity was 18.3% (35/191), which was highly significant, versus an asymptomatic comparison group (7.5%, 11/146). LAI test sensitivity, specificity, and positive and negative predictive values were, respectively, 19.8, 82.7, 45.7, and 58.5%. In this study the LAI test was not found to be a sensitive screening test for colorectal neoplasms. However, as the LAI test result was a significant finding within the study group, it may possibly be a risk factor and identify a subgroup that will require careful prospective evaluation.
