Summary
Understanding Ewing sarcoma biology is crucial for developing new treatments. Current therapies are limited, especially for metastatic cases, highlighting the need for molecular and antiangiogenic approaches.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Ewing sarcoma is a rare bone cancer.
- It is characterized by specific chromosomal translocations.
- Current treatments have limitations, particularly for advanced disease.
Purpose of the Study:
- To review the literature on Ewing sarcoma biology.
- To assess the impact of biological understanding on treatment development.
- To identify future therapeutic strategies.
Main Methods:
- Literature search of PubMed and The Cochrane Collaboration.
- Analysis of preclinical and clinical research, excluding case reports.
- Focus on recent primary research articles and reviews.
Main Results:
- Ewing sarcoma is linked to specific chromosomal translocations and resultant proteins.
- Advances in understanding have not yet led to significant new treatments.
- Survival rates have improved for localized disease but not for metastatic or recurrent cases.
Conclusions:
- Improved prognosis requires better biomarkers and early diagnosis.
- Identifying the cell of origin is essential.
- Developing molecular therapeutics and antiangiogenic agents holds promise.
- Preclinical data support molecular therapies; early clinical results need further evaluation.

02:30Metastasis
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...

01:03Rous 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...

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
