Two UNC scientists, both national experts who have served on numerous guideline development groups, are co-authors: Michael Pignone, MD, MPH, professor of medicine and chief of the division of general medicine and epidemiology, and David Ransohoff, MD, professor of medicine and clinical professor of epidemiology in the UNC Gillings School of Global Public Health. Both are members of UNC Lineberger Comprehensive Cancer Center.
Pignone has served on guideline panels for the American Diabetes Association and American Heart Association, advisory panels for the National Committee on Quality Assurance and has performed systematic evidence reviews for the US Preventive Services Task Force.Ransohoff has served as a reviewer in the guidelines-making process of the US Preventive Services Task Force and the European Union.
Shelley Earp, MD, professor of medicine and pharmacology and director of UNC Lineberger Comprehensive Cancer Center, said, "We applaud the efforts of the American Cancer Society to address the challenging and sometimes emotional issue of cancer screening guidelines.
“Mike Pignone and David Ransohoff are experts in evaluating large scale data sets and distilling knowledge into practice guidelines that make sense. Their participation and co-authorship of the new ACS process speaks to their international leadership in this important area.”
The new process stresses transparency, with activities and timelines posted publicly on the American Cancer Society web site. To align with the new IOM standards, the ACS process will separate expert input from the writing of the guideline, so an independent writing group will receive appropriate subspecialty expertise while protecting it from the appearance of professional conflict of interest.
The process will incorporate a systematic evidence review that will use methods consistent with IOM standards, and the guidelines group will grade the strength of its recommendations. The guidelines will explicitly describe potential benefits and harms of screening and will articulate any differences between its recommendations and those of other groups and the reasons for those differences.
The new process will conclude with a formal review that will include opportunities for experts and professional organizations to comment on draft guidelines. Finally, the guideline process itself will be reviewed periodically by an independent advisory group to assure clarity, utility, and influence of the guidelines. There will be a formal review and rewriting of every ACS cancer screening guideline at least every five years.
“Historically, the ACS has convened ad hoc screening guideline groups to come up with its recommendations for methods of cancer screening,” said Tim Byers, MD, MPH, of the Colorado School of Public Health. Dr Byers headed the Guidelines Process Workgroup convened by the ACS Board of Directors in 2010 and co-authored the new report. “Although that approach has resulted in highly credible and useful guidelines, we saw that the ACS process could be improved in terms of consistency, transparency, scientific rigor, and communications. This new process should ensure that ACS will remain the national leader in creating and communicating trustworthy information to guide clinical practice, personal choices, and public policy about cancer screening.”
