AIM To investigate the diagnostic significance of cytology and telomerase activity in the exfoliated cells ofcardia obtained from endoscopic brushing in the cardiac cancer.METHODS The techniques of the qualitative TRAP-silver staining and quantitative TRAP-PCR-ELISAwere employed to detect telomerase activity in the exfoliated cells of cardia obtained from endoscopicbrushing in 72 cases with cardial lesions, cytological diagnosis was made at the same time.RESULTS Telomerase activity with cardiac cancer group (1.521 ± 0. 192) was significantly higher than thatwith cardialitis group (0.065± 0.014). Positive rate of telomerase activity detected in cardiac cancer group(88.89%) was significantly higher than that with cardialitis group (11.11%), the former was significantlyhiger than cytological examination (77.78%). The diagnostic rate of cardiac cancer reached 93.33% iftelomerase activity and cytology were examined at the same time.CONCLUSION Cytology and telomerase activity in the exfoliated cardiac cells may be an effective andsensitive methods in the diagnosis of cardiac cancer. This research can be a basis for the mass screening ofcardiac cancer.
