Peer review in carcinogenicity bioassays: uses/abuses

Area of Science:

• Pathology
• Regulatory Science
• Biomedical Research

Background:

• Scientific truth relies on rigorous validation processes.
• Peer review is a cornerstone of scientific integrity.
• Diagnostic pathology plays a critical role in regulatory bioassays for drugs and medical devices.

Purpose of the Study:

• To examine the critical role of peer review in diagnostic pathology for regulatory submissions.
• To identify sources of bias in pathology peer review and their impact on study credibility.

Main Methods:

• The study analyzes the inherent subjectivity of diagnostic pathology.
• It discusses potential biases introduced during pathological material handling, interpretation, and reviewer selection.
• The importance of proper study design and reviewer expertise is highlighted.

Main Results:

• Pathology interpretations are central to bioassay outcomes in regulatory science.
• Subjectivity in diagnostic pathology can introduce bias, affecting results.
• Peer review, while intended to reduce bias, can also be a source of bias if not conducted properly.

Conclusions:

• Effective pathology peer review is essential for assuring the validity of results in regulatory bioassays.
• Improperly conducted peer review can compromise study credibility.
• Mitigating bias in pathology peer review is critical for reliable drug and medical device approval.
