High-risk HPV platforms and test of cure: should specific HPV platforms more suited to screening in a ‘test of cure’ scenario be recommended?

tial increase in the number of cytology-negative/hrHPV-positive test-of-cure (ToC) samples after large loop excision of the transformation zone (LLETZ) was noted. We explore the potential reasons for these increased rates and discuss the implications this may have on the English NHS cervical screening programme (CSP). Methods: A retrospective cohort study with interval analysis between June 2007 and June 2012. Results: ToC was performed on 1530 women with HC2 and 396 with cobas 4800: 95.1% and 92.4% of women had negative cytology at ToC in the HC2 and cobas4800 testing period, respectively. Of these 13.9% and 27.8% tested positive for hrHPV in the HC2 and cobas 4800 group, respectively (P =< 0.0001). No clinically significant increase in the number of cases of cervical intraepithelial neolpasia (CIN) was detected by the cobas4800 test in spite of doubling the number of cytology-negative/hrHPV-positive ToC samples. Conclusions: As far as we are aware, this is the first study reporting potential differences between different HPV platforms currently available in the English programme. The immediate impact of this increase in rates of hrHPV detection with cobas4800 is an increased number of colposcopy referrals to our service. The NHSCSP needs to assess whether this increase is acceptable and, if not, whether specific HPV platforms more suited to screening in a ToC scenario should be recommended.
