We provide a general framework for describing various roles for biomarkers in cancer prevention research (early detection, surrogate endpoint, and cohort identification for primary prevention) and the phases in their evaluation.
Accounting for subject nonadherence and eliminating inappropriate subjects in clinical trials are critical elements of a successful study. Nonadherence can increase variance, lower study power, and reduce the magnitude of treatment effects. Inappropriate subjects (including those who do not have the illness under study, fail to report exclusionary conditions, falsely report medication adherence...
Introduction Conclusions References
Following publication of the original article [1], the authors reported that there was a mistake in the Methods section → Measurements of biomarkers (page 6, line 3): 2000g should read 2500g. So, the correct sentence should be "All samples were obtained by venipuncture into serum monovettes® and centrifuged at 2500g for 10 min at 20 °C."
Biomarkers may be qualified using different qualification processes. A passive approach for qualification has been to accept the end of discussions in the scientific literature as an indication that a biomarker has been accepted. An active approach to qualification requires development of a comprehensive process by which a consensus may be reached about the qualification of a biomarker. Active ...
The 12th meeting of the Scientific Group on Methodologies for the Safety Evaluation of Chemicals (SGOMSEC) considered the topic of methodologies for determining human and ecosystem susceptibility to environmental hazards. The report prepared at the meeting describes measurement of susceptibility through the use of biological markers of exposure, biological markers of effect, and biomarkers dire...
