Summary
The immune system can prevent tumor growth by holding cancer in a dormant state, a concept known as cancer immunoediting. Future research aims to leverage this for new cancer immunotherapies.
Area of Science:
- Immunology
- Oncology
- Cancer Research
Background:
- The immune system plays a critical role in tumor development.
- Cancer immunoediting describes the dynamic interplay between cancer and immunity.
Purpose of the Study:
- To review the concept of cancer immunoediting, focusing on the equilibrium phase.
- To present evidence for immune-mediated cancer dormancy.
- To establish a framework for developing novel immunotherapeutic strategies.
Main Methods:
- Literature review of cancer immunity and immunoediting.
- Detailed examination of the equilibrium phase of immunoediting.
- Description of a mouse model demonstrating immune control of preformed tumors.
Main Results:
- Cancer immunoediting involves elimination, equilibrium, and escape phases.
- Immunity can maintain established tumors in a dormant state (equilibrium).
- A mouse model confirmed that immunity can control preformed cancers.
Conclusions:
- Immune-mediated cancer dormancy is a validated phenomenon.
- Findings support further investigation into human cancer dormancy.
- This research provides a basis for developing new cancer immunotherapies.

Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cell-mediated Immune Responses
Overview
Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
