Abstract:
Metastases are a major cause of cancer-related death and despite the fact that they have been focus of intense research over the last two decades, effective therapies for patients with distant secondary lesions are still very limited. In addition, in some tumor types metastases can grow years after the patients have been declared clinically cured, indicating that disseminated cancer cells (DCCs) persist undetected for years, even decades in a quiescent state. Clinical and experimental data highlight the importance of the immune system in shaping the fitness and behaviour of DCCs. Here, we review mechanisms of survival, quiescence and outgrowth of DCCs with a special focus on immune-regulation and we highlight the latest cutting-edge techniques for modelling the biology of DCCs in vitro and for studying the metastatic niche in vivo. We believe that a wide dissemination of those techniques will boost scientific findings towards new therapies to defeat metastatic relapses in cancer patients.
Insights
Metastases cause many cancer deaths, with limited therapies for secondary lesions. This review explores how the immune system influences dormant disseminated cancer cells (DCCs) and discusses new research techniques.
Area of Science:
- Oncology
- Immunology
- Cancer Metastasis Research
Background:
- Metastases are a leading cause of cancer mortality, with limited effective treatments for distant secondary lesions.
- Disseminated cancer cells (DCCs) can remain dormant for years, leading to late relapses even after apparent cure.
- The immune system plays a critical role in regulating the survival, dormancy, and outgrowth of DCCs.
Purpose of the Study:
- To review mechanisms governing the survival, quiescence, and outgrowth of DCCs.
- To emphasize the role of immune regulation in the metastatic process.
- To highlight advanced techniques for studying DCC biology and the metastatic niche.
Main Methods:
- Review of existing clinical and experimental data on cancer metastasis and immune interaction.
- Focus on immune-regulatory mechanisms affecting disseminated cancer cells.
- Discussion of cutting-edge in vitro and in vivo modeling techniques.
Main Results:
- The immune system significantly influences the behavior and fate of disseminated cancer cells.
- Understanding immune regulation is key to addressing dormant DCCs.
- New in vitro and in vivo models are crucial for advancing DCC research.
Conclusions:
- Effective therapies for metastatic cancer remain limited, necessitating further research into DCC biology.
- Targeting immune regulation of DCCs holds promise for preventing metastatic relapse.
- Dissemination of advanced modeling techniques will accelerate discoveries for novel anti-metastasis therapies.
