Insights

This review examines outcomes for infants diagnosed with rhabdomyosarcoma (RMS). It highlights strategies to minimize treatment side effects while maintaining survival rates for this rare pediatric cancer.

Area of Science:

  • Pediatric Oncology
  • Rare Cancers
  • Clinical Trials

Background:

  • Rhabdomyosarcoma (RMS) predominantly affects children and adolescents.
  • A small subset of RMS cases occur in infants under one year of age.
  • Infant RMS studies yield varied results due to rarity and differing treatment protocols.

Purpose of the Study:

  • To review outcomes for infants with RMS treated in clinical trials.
  • To discuss strategies used by international groups to reduce treatment-related morbidity and mortality.
  • To explore novel diagnostic and management approaches for infant RMS.

Main Methods:

  • Review of outcomes from infant RMS clinical trials.
  • Analysis of treatment strategies from international cooperative groups.
  • Discussion of unique RMS subtypes: congenital/neonatal, spindle cell, and relapsed.

Main Results:

  • Heterogeneous results reported in existing literature due to small sample sizes and varied approaches.
  • International cooperative groups are actively developing strategies to improve infant RMS care.
  • Novel approaches are under investigation to enhance diagnosis and management.

Conclusions:

  • Infant RMS requires specialized approaches due to its rarity and unique clinical scenarios.
  • Reducing treatment toxicity without compromising survival is a key focus.
  • Ongoing research into novel diagnostic and therapeutic strategies holds promise for improving outcomes.

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...

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
