Esophageal Cancer Evolution

Esophageal Cancer

Evolution of Esophageal Cancer

1 Normal cell stage

  • Characteristics: The esophageal mucosa is composed of normal epithelial cells, with regular cell morphology and normal function.

2 Pre-cancerous lesion stage

  • Low-grade intraepithelial neoplasia (LGIN):
    • Characteristics: Cells show mild atypia, but have not breached the basement membrane. Cell proliferation capacity is enhanced, but the degree of differentiation is still relatively high.
    • Genetic changes: TP53 gene monoallelic mutations may occur, but the mutation frequency is low. Other genes, such as NOTCH1, have a higher mutation frequency.
  • High-grade intraepithelial neoplasia (HGIN):
    • Characteristics: Significant increase in cell atypia, further enhancement of cell proliferation capacity, and a decrease in the degree of differentiation. Cells may breach the basement membrane, but have not yet formed invasive cancer.
    • Genetic changes: Clones with biallelic deletion of the TP53 gene gradually dominate, and genomic instability increases.

3 Carcinoma in situ stage

  • Characteristics: Cancer cells are confined within the epithelial layer and have not breached the basement membrane, but have already acquired the morphology and biological characteristics of cancer cells.
  • Genetic changes: Clones with biallelic deletion of the TP53 gene further expand, and genomic instability significantly increases.

4 Invasive cancer stage

  • Characteristics: Cancer cells breach the basement membrane, invade the lamina propria or deeper tissues, and form invasive cancer. Tumors may further invade the various layers of the esophageal wall, and even involve surrounding tissues and organs.
  • Genetic changes: The tumor mutation burden further increases, especially with a significant increase in copy number variations (CNAs). Clones with biallelic deletion of the TP53 gene continue to dominate.

5 Further development and metastasis stage

  • Locally advanced stage:
    • Characteristics: Tumors invade deeper layers of the esophageal wall and may involve surrounding tissues and organs, such as the trachea, bronchi, lungs, and pericardium.
    • Genetic changes: Genomic instability further intensifies, and new genetic mutations and copy number variations continue to emerge.
  • Distant metastasis stage:
    • Characteristics: Cancer cells metastasize to distant organs through the lymphatic or blood system, such as the liver, lungs, bones, etc.
    • Genetic changes: Genomic instability reaches its peak, and the invasive and metastatic capabilities of tumor cells are significantly enhanced.

6 Terminal stage

  • Characteristics: Widespread metastasis of tumors leads to multiple organ failure, and patients enter the terminal stage.

Understanding the evolution of esophageal cancer helps in early detection and intervention, improving treatment outcomes and patient survival rates. Early detection and intervention can significantly improve prognosis, especially when intervention is carried out at the pre-cancerous lesion stage, which can effectively prevent further cancer development.
