Abstract

Insights

Human papillomavirus (HPV) infection may play a role in retinoblastoma (RB), the most common childhood eye cancer. Studies show a wide prevalence range (0-69%), indicating more research is needed to confirm the association.

Area of Science:

  • Ophthalmology
  • Oncology
  • Virology

Background:

  • Retinoblastoma (RB) is the most frequent intraocular malignancy in young children, accounting for 3-5% of childhood cancers.
  • Emerging research suggests a potential interaction between RB tumor suppressors and human papillomavirus (HPV) oncoproteins.

Purpose of the Study:

  • To systematically review existing studies investigating the potential role of HPV infection in retinoblastoma.

Main Methods:

  • A systematic literature search was conducted across major databases (PubMed, Embase, Scopus, Google Scholar, Web of Science).
  • Studies were screened based on PRISMA criteria, focusing on original research in English.
  • Data extraction was performed on 8 selected studies.

Main Results:

  • The prevalence of HPV in retinoblastoma samples varied widely, ranging from 0% to 69%.
  • HPV genotypes 16 and 18 were the most frequently detected types.
  • Polymerase chain reaction (PCR) was the primary detection method, with formalin-fixed, paraffin-embedded tissues being the most common sample type.

Conclusions:

  • The current evidence on the association between HPV and retinoblastoma remains inconsistent.
  • The broad prevalence range (0-69%) underscores the need for further investigation.
  • Larger, worldwide cohort studies are recommended to clarify the prevalence and role of HPV in retinoblastoma.
