Rous Sarcoma Virus (RSV) and Cancer

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

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,...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Area of Science:

Oncology
Pathology
Genetics

Background:

Malignant small round cell tumors (MSRCTs) are a group of neoplasms characterized by small, undifferentiated cells.
Differential diagnosis is difficult due to the primitive nature of these tumors, often hindering definitive morphological identification.
Common examples include Ewing's sarcoma, neuroblastoma, and Wilms' tumor, among others.

Purpose of the Study:

To highlight the diagnostic challenges associated with malignant small round cell tumors.
To emphasize the utility of fine needle aspiration cytology (FNAC) in obtaining diagnostic material.
To review the ancillary techniques crucial for accurate classification of MSRCTs.

Main Methods:

Fine needle aspiration cytology (FNAC) for cell collection.
Immunohistochemistry and immunophenotyping by flow cytometry.
Molecular genetic approaches including RT-PCR and FISH.

Main Results:

FNAC provides viable cells suitable for various ancillary diagnostic techniques.
A multimodal diagnostic approach combining cytology with ancillary methods improves classification accuracy.
Molecular genetic characterization of chromosomal breakpoints and genes offers precise detection capabilities.

Conclusions:

Accurate diagnosis of MSRCTs often requires a combination of morphological assessment and advanced ancillary techniques.
FNAC is a valuable initial diagnostic tool for MSRCTs.
Molecular diagnostics play an increasingly important role in the precise classification and understanding of MSRCTs.
