Chromosomal translocations highlighted in Primitive Neuroectodermal Tumors (PNET) and Ewing sarcoma

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Over 200 molecular markers in oncology are vital for cancer diagnosis, prognosis, and treatment.
• Tumor markers encompass genetic alterations, gene expression changes, protein level variations, and functional cellular differences.
• Cancer is fundamentally a genetic disease driven by deregulation of cell division and growth control pathways.

Purpose of the Study:

• To highlight the significance of molecular markers in understanding cancer biology.
• To define the scope and types of molecules and processes classified as tumor markers.
• To emphasize the genetic basis of cancer, including oncogenes and regulatory pathways.

Main Methods:

• Identification and characterization of molecular alterations at genetic, transcriptional, translational, and functional levels.
• Analysis of cell, tissue, and circulating (sanguine) markers.
• Investigation of regulatory mechanisms controlling cell growth, differentiation, senescence, and apoptosis.

Main Results:

• Established the importance of nearly 200 molecular markers in oncology.
• Detailed the diverse nature of tumor markers, including genetic mutations, gene amplifications, altered protein expression, and abnormal glycosylation.
• Confirmed cancer as a genetic disease involving oncogenes and dysregulated cell cycle control.

Conclusions:

• Molecular tumor markers are indispensable tools in modern oncology.
• Understanding these markers aids in diagnosing, predicting, and treating various cancers.
• The genetic underpinnings of cancer necessitate a comprehensive analysis of molecular alterations.
