To study the HPV viral load (VL) in the prediction of the persistence and/or progression in LSIL cases.
Prospective study. 102 consecutive cases diagnosed as LSIL in 2006 with follow-ups at 6, 12 and 24 months subsequent to diagnosis.
Liquid based cytology (ThinPrep庐, Hologic, Malborough, MA, USA), for the cytological study. Hybrid Captute II Test (HCII-HR, Quiagen, Hilden, Germany), for the determination of the presence or absence of High-Risk HPV.
87 of the 102 cases studied were HR-HPV positive (85.3%). The presence or progression was detected in 54%, 42%and 33.35%of the cases in the first, second and third controls respectively. No lesion was demonstrated in 46%, 57%and 66.7%of the cases at first, second and third controls respectively. 19 cases progressed to HSIL; 11 of which were detected on the first control, 6 on the second and 2 on the third. The sensitivity of the VL for detecting HSIL never exceeded 89%, with a specificity always inferior to 40%.
The VL determined by the HC2 method is not a useful indicator of prognosis in the follow-up of LSIL cases.
