Tumor cell plasticity, including epithelial-to-mesenchymal transition (EMT), drives cancer immune evasion and resistance. Targeting this plasticity offers a new strategy for more effective cancer immunotherapies.
Area of Science:
- Oncology
- Cancer Immunology
- Cell Biology
Background:
- Tumor cell plasticity is critical for tumor progression and evading immune surveillance.
- Mechanisms like epithelial-to-mesenchymal transition (EMT) contribute to tumor cell plasticity and immune evasion.
Purpose of the Study:
- To review recent evidence on tumor cell plasticity, its role in generating immunoresistant variants, and the influence of the tumor microenvironment.
- To propose targeting tumor cell plasticity as a novel therapeutic strategy for improving cancer treatment outcomes.
Main Methods:
- Literature review and synthesis of recent research findings.
- Discussion of mechanisms linking tumor cell plasticity, immune evasion, and therapeutic resistance.
Main Results:
- Tumor cell plasticity can lead to the development of variants resistant to immunotherapy.
- The tumor microenvironment actively shapes tumor cell plasticity and the emergence of resistant phenotypes.
Conclusions:
- Targeting carcinoma cell plasticity is a promising strategy to prevent the emergence of resistant variants.
- Developing innovative, integrated immunotherapy approaches is essential for overcoming treatment resistance and improving patient outcomes.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Tumor Progression
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...
