Harnessing Real-World Evidence to Advance Cancer Research

Area of Science:

• Oncology research
• Clinical trial methodology
• Real-world data analysis

Background:

• Randomized controlled trials (RCTs) are crucial for oncology research but can be resource-intensive and limited in generalizability.
• Real-world evidence (RWE) uses data from routine clinical care to complement RCT findings.
• Gaps exist between RCT evidence and clinical practice, necessitating alternative data sources.

Purpose of the Study:

• To review the strengths and limitations of both RCTs and RWE in oncology.
• To propose a framework for the complementary use of RCT and RWE.
• To advance cancer research by integrating different evidence types.

Main Methods:

• Literature review of RCTs and real-world evidence in oncology.
• Analysis of challenges in real-world data collection and causal inference.
• Framework development for integrating diverse evidence sources.

Main Results:

• RCTs provide robust efficacy data in select populations, while RWE reflects broader clinical practice.
• Challenges in RWE include data heterogeneity, access, and methodological quality, particularly for causal inference.
• A framework for complementary use can enhance the reliability and acceptance of RWE.

Conclusions:

• Integrating RCTs and RWE is essential for comprehensive cancer research.
• Addressing RWE challenges will improve its utility in oncology.
• Optimizing RWE research will realize its full potential in clinical practice.
