Abstract:
Metastasis is the primary cause of death in cancer patients and current treatments fail to provide durable responses. Efforts to treat metastatic disease are hindered by the fact that metastatic cells often remain dormant for prolonged intervals of years, or even decades. Tumor dormancy reflects the capability of disseminated tumor cells (DTCs), or micrometastases, to evade treatment and remain at low numbers after primary tumor resection. Unfortunately, dormant cells will eventually produce overt metastasis. Innovations are needed to understand metastatic dormancy and improve cancer detection and treatment. Currently, few models exist that faithfully recapitulate metastatic dormancy and metastasis to clinically relevant tissues, such as the bone. Herein, we discuss recent advances describing genetic cell-autonomous and systemic or local changes in the microenvironment that have been shown to endow DTCs with properties to survive and eventually colonize distant organs.
Insights
Metastatic cancer cells can remain dormant for years, evading treatment and treatment detection. Understanding tumor dormancy mechanisms is crucial for developing new therapies to combat cancer spread and improve patient survival.
Area of Science:
- Oncology
- Cancer Biology
- Cellular Biology
Background:
- Metastasis is the leading cause of cancer-related mortality, with current treatments often failing to achieve lasting results.
- Tumor dormancy, characterized by dormant disseminated tumor cells (DTCs), poses a significant challenge, as these cells can evade therapy and persist for years before causing overt metastasis.
- Effective models that accurately replicate metastatic dormancy and colonization of critical tissues like bone are scarce, hindering research and therapeutic development.
Approach:
- This review synthesizes recent advancements in understanding the factors contributing to metastatic dormancy.
- It explores both intrinsic genetic properties of DTCs and extrinsic microenvironmental changes that promote their survival and colonization.
- Focuses on models that recapitulate dormancy and metastasis to clinically relevant tissues, particularly bone.
Key Points:
- Dormant disseminated tumor cells (DTCs) can evade cancer treatments and persist for extended periods.
- Both genetic factors within DTCs and the surrounding microenvironment influence their survival and ability to colonize distant sites.
- The development of improved models is essential for studying metastatic dormancy and bone metastasis.
Conclusions:
- Further research into the mechanisms of tumor dormancy is vital for improving cancer detection and treatment strategies.
- Targeting both cell-autonomous and microenvironmental factors may offer novel therapeutic avenues for managing metastatic disease.
- Innovations in modeling metastatic dormancy are needed to advance our understanding and clinical management of cancer metastasis.
