Tumor Progression02:07

Tumor 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...

Summary

Diagnosing small intestinal tumors is challenging due to inaccessibility. Advanced endoscopic and radiologic tools now improve visualization and accuracy for better patient surveillance and minimally invasive therapies.

Area of Science:

  • Gastroenterology
  • Oncology
  • Medical Imaging

Background:

  • Small intestinal tumors present diagnostic challenges due to their location and non-specific symptoms.
  • Accurate diagnosis is crucial for effective patient management and treatment.
  • Traditional diagnostic methods have limitations in visualizing the small bowel.

Purpose of the Study:

  • To review the general aspects of small intestinal tumors.
  • To focus on novel diagnostic modalities for small intestinal tumors.
  • To highlight advancements in endoscopic and radiologic technologies for small bowel visualization.

Main Methods:

  • Review of current endoscopic technologies, including balloon-assisted enteroscopy.
  • Analysis of advanced radiologic imaging techniques for small bowel assessment.
