samples from 856 subjects were collected using aspiration and brush methods. Cytological examination results showed suspicious or positive findings in either or both methods compared to those of histological examinations. Results In the 1099 samples, the difference in the proportion of samples unsatisfactory for evaluation in the aspiration and brush methods was statistically significant at 15.6 versus 5.3 p 0.01. Among 160 subjects with suspicious or positive results in either or both methods, 120 75 had endometrial cancer or associated lesions. The rate of suspicious or positive findings in the aspiration method was 94.2 113 120 versus the brush method at 93.3 112 120. Conclusion The diagnostic accuracy of the brush method appears equivalent to that of the aspiration method. The ratio of samples unsatisfactory for evaluation with the brush method was significantly lower, however, than for evaluation with the aspiration method. The brush method may therefore be advantageous when used as a tool for screening endometrial cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
