ObjectivesThis study was conducted to determine the prognostic significance of the human papillomavirus (HPV) genotype using the HPV DNA chip (HDC) test and the HPV viral load by the hybrid capture II assay (HC2) in FIGO stage IB–IIA cervical cancer undergoing radical hysterectomy.MethodsBetween January 2001 and December 2005, 204 consecutive patients who underwent radical hysterectomy with pelvic lymphadenectomy for International Federation of Gynecology and Obstetrics (FIGO) stage IB1–IIA cervical cancer were retrospectively reviewed. The Cox proportional hazard models adjusted for covariates were used for analyses and a receiver operating characteristic (ROC) curve was used to determine the HPV viral load in predicting disease progression.ResultsOf the 204 cases, the HDC was positive in 195 (95.6%) and the HC2 was positive in 192 (94.1%). The 5-year progression-free survival (PFS) was 78.4%. On multivariate analysis, HPV-18 positivity was an independent prognostic factor predictive for disease progression. The risk of recurrence was higher for HPV-18 positivity (hazard ratio = 2.664; 95% confidence interval [CI], 1.437–4.938; P = 0.003). The 5-year PFS rate for patients who were HPV-18-negative was 83.8%, which was higher than the 5-year PFS for patients who were HPV-18-positive (54.1%; P < 0.001). The area under the ROC curve for the HPV viral load was 0.550 (P = 0.314; 95% CI, 0.455–0.644).ConclusionsThe HPV-18 genotype is a reliable prognostic factor of early-stage cervical cancer; however, the HPV viral load may not be helpful in predicting disease prognosis.
Research Highlights►The HPV DNA chip test is a newly developed biotechnology which may be applied for the detection and typing of HPV. ►The HPV viral load is not sufficient for predicting recurrent cervical cancer. ►The HPV-18 genotype provides an important tool in determining the prognosis of clinical outcome for FIGO stage IB–IIA.
