Abstract

Objective: Since the accuracy of Pap smear for cervical neoplasm has been questioned, a number of adjunctive tests have been developed. The purpose of this study was to evaluate which protocol is the most effective screening test among cervical cytology (ThinPrep(R)), HPV DNA test (Hybrid capture(R) II) and cervicography.

Methods: We chose 252 patients who were underwent the biopsy among 829 patients who visited our hospital for cervical cancer screening test. These 252 patients were engaged in this study simultaneously. They underwent triple combined test [cervical cytology (ThinPrep(R)), HPV DNA test (Hybrid capture(R) III, cervicography] and colposcopic-directed biopsy or biopsy on operation for diagnostic evaluation.

Results: The triple combined test showed a sensitivity of 96.0%, while double combined test [cervical cytology (ThinPrep(R))+cervicography] showed a sensitivity of 89.0%, the other double combined test [cervical cytology (ThinPrep(G))+HPV DNA test (Hybrid capture(R) III] showed a sensitivity of 86.7%. Cervicography showed a specificity of 75.4% (highest among the single test), positive predictability of 89.8% (also highest).

Conclusion: The sensitivity of cervical cytology was markedly improved by combination with HPV DNA test and cervicography. So the triple combined tests which improved the high false negative rate of cervical cytology may be a new effective method as a cervical cancer screening test, if the effectiveness could be confirmed by mass screening study.
