The dormant cancer cell life cycle.

Area of Science:

• Oncology
• Cancer Biology
• Translational Medicine

Background:

• Targeted therapies and immunotherapies show promise for cancer cure, but drug resistance and relapse remain significant challenges.
• Relapse is often caused by dormant cancer cells that evade treatment and hide in specific niches.
• Current research faces hurdles due to inconsistent definitions, limited models, and lack of interdisciplinary approaches.

Purpose of the Study:

• To synthesize recent advances in understanding cancer cell dormancy.
• To describe the hallmarks of cancer cell dormancy and its life cycle.
• To identify opportunities for targeting dormant cells and their microenvironment for durable cancer cures.

Main Methods:

• Review and synthesis of recent scientific literature.
• Application of high-resolution, single-cell technologies.
• Analysis of cellular ecosystems and transcriptional landscapes controlling dormancy.

Main Results:

• Cancer cell dormancy is characterized by specific hallmarks and a distinct life cycle.
• Single-cell technologies provide a global view of the complex factors controlling dormancy.
• Dormant cancer cells can be targeted, along with their environment, to prevent relapse.

Conclusions:

• Understanding cancer cell dormancy is crucial for preventing disease relapse.
• Targeting dormant cancer cells and their niches offers a promising strategy for achieving durable cancer cures.
• Interdisciplinary approaches and advanced technologies are key to overcoming challenges in this field.
