HPV Genotyping Linear Assay Test Comparison in Cervical Cancer Patients: Implications for HPV Prevalence and Molecular Epidemiology in a Limited-resource Area in Bandung, Indonesia

Background: Persistent infection with high risk human papillomavirus (hrHPV) is strongly associated with cervical cancer. Normal cervical cells may also harbor hrHPV, and detection of early hrHPV infection may minimize risk of cervical cancer development. This study aimed to compare two commercial HPV genotyping assays that may affordable for early screening in a limited-resource setting in Bandung, Indonesia. Materials and Methods HPV genotyped by Linear Assay 1 (Roche Diagnostics, Mannheim, Germany) or Linear Assay 2 (Digene HPV Genotyping RH Test, Qiagen Gaithersburg, MD). In a subset of samples of each group, HPV genotype results were then compared. Results: Of 28 samples genotyped by linear assay 1, 22 (78.6%) demonstrated multiple infections with HPV-16 and other hrHPV types 18, 45 and/or 52. In another set of 38 samples genotyped by linear assay 2, 28 (68.4%) were mostly single infections by hrHPV type 16 or 18. Interestingly, 4 samples that had been tested by both kits showed discordant results. Conclusions: In a limited-resource area such as in Indonesia, country with a high prevalence of HPV infection a reliable cervical screening test in general population for early hrHPV detection is needed. Geographical variation in HPV genotyping result might have impacts for HPV prevalence and molecular epidemiology as the distribution in HPV genotypes should give clear information to assess the impact of HPV prophylactic vaccines.
