Molecular detection methods of human papillomavirus (HPV)

Area of Science:

• Molecular Biology
• Gynecologic Oncology
• Virology

Background:

• Cervical cancer risk is identified through Human Papillomavirus (HPV) testing.
• Molecular detection methods are the current gold standard for HPV identification.

Purpose of the Study:

• To review and compare different molecular assays for HPV detection.
• To highlight the advantages of PCR-based methods for HPV DNA detection.

Main Methods:

• Comparison of non-amplified hybridization assays (Southern transfer hybridization, dot blot hybridization, in situ hybridization).
• Evaluation of signal amplified hybridization assays (Hybrid Capture 2).
• Analysis of target amplification assays (Polymerase Chain Reaction, in situ PCR).

Main Results:

• Non-amplified methods like STH are laborious and not reproducible; ISH has moderate sensitivity.
• Hybrid Capture 2 (HC2) shows sensitivity comparable to PCR.
• Polymerase Chain Reaction (PCR) offers high sensitivity and specificity, ideal for low DNA content specimens.

Conclusions:

• PCR-based detection is highly sensitive and specific for HPV DNA.
• Advancements in technology will lead to more rapid, sensitive, and automated viral DNA extraction and amplification systems.
