Abstract

BACKGROUND:

Self-sampling for human papillomavirus (HPV) is useful for triage of ASCUS Papanicolaou (Pap) smears. Tampons with 10-second cervicovaginal cell exposure can detect HPV but appear to be less efficient than two consecutive swabs.

GOAL:

The purpose of this study was to evaluate increased vaginal tampon exposures for detecting high-risk HPV.

STUDY DESIGN:

This longitudinal cohort study followed women who self-sampled weekly with tampons for progressively longer periods of time. A tampon was inserted for 10 seconds at the office visit and 1 hour, 4 hours, and overnight for the three subsequent home samples. Two concurrent swabs were used with each tampon sampling for contemporaneous comparisons. The MY09/MY11 PCR primer system with reverse line blot detection strips was used to detect 18 distinct high-risk HPV types.

RESULTS:

Of the 309 tampons and 618 swabs used at home, 83% were returned. Among normal women, the 10-second tampon detected fewer with normal histology and high-risk HPV than did its swabs ( = 0.0412), but the 1-hour, 4-hour, and overnight tampons had high-risk-HPV detection rates equal to their swabs. In women with CIN, all tampons and swabs equally identified those with high-risk HPV.

CONCLUSION:

Self-sampling for HPV detection is acceptable, feasible, and technically accurate for both tampons with longer cervicovaginal exposures and swabs. The choice of technique is dependent on the woman, her culture, and her clinician.
