Insights

Viruses are a major cause of hematologic malignancies (HMs). This review details key viruses linked to HMs, their mechanisms, and management strategies for clinicians.

Area of Science:

  • Oncology
  • Virology
  • Hematology

Background:

  • Hematologic malignancies (HMs) represent a significant global health burden, with over one million new cases in 2020.
  • Infectious agents, particularly viruses, are recognized as significant contributors to oncogenesis in hematologic cancers.
  • Understanding viral associations is crucial for managing HMs and preventing complications.

Purpose of the Study:

  • To review the current understanding of viral associations with hematologic malignancies.
  • To identify key viruses implicated in HM development and their oncogenic mechanisms.
  • To provide an overview of current management principles for virus-associated HMs.

Main Methods:

  • A comprehensive literature search of the PubMed database was conducted.
  • The review focused on identifying evidence linking specific viruses to hematologic malignancies.
  • Information on oncogenic mechanisms and clinical management was synthesized.

Main Results:

  • Epstein-Barr virus, human immunodeficiency virus, human T-lymphotropic virus, hepatitis C virus, and Kaposi sarcoma herpesvirus show strong evidence of association with HMs.
  • Reactivation of latent hepatitis B virus is a concern during HM treatment regimens.
  • Mechanisms of viral oncogenesis and current management strategies are summarized.

Conclusions:

  • Viruses play a critical role in the etiology of many hematologic malignancies.
  • Clinicians can utilize this information to determine malignancy etiology and implement preventive strategies.
  • Effective management requires addressing both the malignancy and the associated viral factors.

Mechanisms of Retrovirus-induced Cancers

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 Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

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...

Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Hematopoiesis01:21

Hematopoiesis

The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
