Mechanisms of Retrovirus-induced Cancers

7.3K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Rous Sarcoma Virus (RSV) and Cancer

6.6K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Summary

Cervical cancer is preventable with regular Papanicolaou (Pap) smear screening. Most "rapid-onset" cancers result from screening failures, not fast-growing tumors, highlighting the need for comprehensive programs.

Area of Science:

  • Gynecology
  • Oncology
  • Preventive Medicine

Background:

  • Cervical cancer is largely preventable through early detection via Papanicolaou (Pap) smears.
  • The concept of "rapid-onset" cervical cancer has been used to justify shorter screening intervals, despite evidence to the contrary.
  • Many invasive cervical cancers are diagnosed in women who have never been screened or have not followed recommended screening guidelines.

Purpose of the Study:

  • To investigate the phenomenon of "rapid-onset" cervical cancer.
  • To identify the primary reasons for screening failures in cases of cervical cancer.
  • To propose essential components for an effective, organized cervical cancer screening program.

Main Methods:

  • Review of screening failure reasons in patients diagnosed with cervical cancer.
  • Analysis of the contribution of inadequate smears, false negatives, and lack of follow-up to "rapid-onset" diagnoses.
  • Evaluation of existing screening program shortcomings.

Main Results:

  • Over 95% of "rapid-onset" cervical cancers are attributable to screening failures, including inadequate or false-negative Pap smears and failure to investigate abnormal results.
  • A significant percentage of cervical cancer patients have either never had a Pap smear or have not adhered to the recommended 3-year screening interval.
  • The "rapid-onset" cancer theory is largely unsupported when screening failures are properly accounted for.

Conclusions:

  • "Rapid-onset" cervical cancer is primarily a consequence of screening program deficiencies, not inherent rapid tumor growth.
  • Effective cervical cancer eradication requires organized, comprehensive screening programs.
  • Key components for success include robust recruitment, a reliable recall system for abnormalities, and stringent quality assurance in cytology and colposcopy.
