Tumor Progression

7.8K
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...

Metastasis02:30

Metastasis

6.8K
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...

Cancer

55.5K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Research

Background:

  • Malignancy progression involves infiltration and metastasis.
  • The tumor microenvironment (TME) is integral to tumor morphology, growth, and invasiveness.
  • The TME comprises extracellular matrix, various cells, and signaling molecules regulating cell communication and tumor progression.

Purpose of the Study:

  • To review tumor cell strategies during progression.
  • To examine the influence of the microenvironment on metastasis formation.
  • To identify the metastatic niche as a potential therapeutic target.

Main Methods:

  • Literature review of tumor progression mechanisms.
  • Analysis of the role of the tumor microenvironment in metastasis.
  • Exploration of pre-metastatic niche formation and function.

Main Results:

  • The TME facilitates tumor cell migration and the establishment of distant growth sites.
  • Primary tumors induce pre-metastatic niches essential for tumor cell survival.
  • Elimination of primary tumors can still lead to metastasis via activated niches.

Conclusions:

  • Understanding TME's role in metastasis is key to developing effective cancer therapies.
  • The metastatic niche represents a promising target for novel anti-metastatic treatments.
  • Targeting the metastatic niche could offer a new strategy for controlling cancer spread.
