Abstract
Introduction: The persistent infection of the high-risk Human Papiloma Virus (VPH-AR in Spanish) causes uterine cervix cancer (CCU in Spanish). There are molecular essays for detection and genotyping of gen L1 of VPH. However, L1 may get lost during the viral integration. The expression and integration of oncogene E7 is fundamental for the development of CCU. Objective: To standardize a multiplex PCR (mPCR) of oncogene E7 (E7-mPCR) for genotyping the VPH-AR of highest frequency in CCU (VPH-16, -18, -31, -33, -45 y -52). Method:
We obtained cervix brushing simples from volunteers and we analyzed them by amplifying the L1 gene through PCR with a sub-sequent reverse hybridization. After that, we chose 59 positive VPH-AR samples and we analyzed them for E7-mPCR. Results: We found out a high concordance between the results of the essay E7-mPCR and those of L1 PC (Observed concordance was of 95.1%, Cohen’s Kappa = 0.88), and we revealed a higher number of infections for VPH-AR in a 15.8% with E7-mPCR. Conclusion: E7-mPCR is an economic diagnostic tool with high concordance which can be adapted to a platform with more complexity to process and detect a higher number of samples and VPH-AR genotypes.
