Abstract:
Historically, therapy of metastatic disease has essentially been limited to using strategies that were identified and established to shrink primary tumors. The limited efficacy of such treatments on overall patient survival stems from diverging intrinsic and extrinsic characteristics of a primary tumor and metastases originating therefrom. To develop better therapeutic strategies to treat metastatic disease, there is an urgent need to shift the paradigm in preclinical metastasis research by conceptualizing metastatic dissemination, colonization, and growth as spatiotemporally dynamic processes and identifying rate-limiting vulnerabilities of the metastatic cascade. Clinically, while metastatic colonization remains the most attractive therapeutic avenue, comprehensive understanding of earlier steps may unravel novel metastasis-restricting therapies for presurgical neoadjuvant application. Moving beyond a primary tumor-centric view, this review adopts a holistic approach to understanding the spatial and temporal progression of metastasis. After reviewing recent developments in metastasis research, we highlight some of the grand challenges and propose a framework to expedite mechanism-based discovery research feeding the translational pipeline.
Insights
Developing effective metastatic disease therapies requires a paradigm shift. Understanding metastasis as a dynamic process, not just primary tumor shrinkage, reveals new therapeutic targets for improved patient survival.
Area of Science:
- Oncology
- Cancer Metastasis Research
Background:
- Current metastatic disease therapies primarily focus on primary tumor shrinkage.
- Limited efficacy of primary tumor-centric strategies is due to intrinsic and extrinsic differences between primary tumors and metastases.
Purpose of the Study:
- To shift the paradigm in preclinical metastasis research by viewing metastasis as a dynamic, spatiotemporal process.
- To identify rate-limiting vulnerabilities within the metastatic cascade for novel therapeutic development.
- To propose a framework for mechanism-based discovery research to advance translational oncology.
Main Methods:
- Review of recent developments in metastasis research.
- Holistic analysis of the spatial and temporal progression of metastasis.
- Identification of challenges and opportunities in metastasis research.
Main Results:
- Current therapeutic strategies for metastatic disease have limited efficacy due to tumor heterogeneity.
- Understanding earlier steps of metastasis, beyond colonization, can reveal novel therapeutic targets.
- A holistic, spatiotemporal approach is crucial for advancing metastasis research.
Conclusions:
- A paradigm shift towards understanding metastasis as a dynamic cascade is essential for developing effective therapies.
- Targeting earlier steps in metastasis, alongside colonization, offers potential for novel treatments.
- A proposed framework can accelerate mechanism-based research for translational application in oncology.
