Research from scientists* across the University of South Carolina and several collaborators from the Baylor College of Medicine has found a link between long-term antibiotic exposure and increased progression of colorectal cancer. Led by Anindya Chanda, assistant professor of environmental health sciences, James Carson, professor and chair of exercise science, and investigators with the USC Center for Colon Cancer Research, the study was published in Cancer Medicine.

The researchers examined the effects of long-term antibiotic exposure on gut microbiota and found an increase in polyps and tumors in the intestinal tract. These results suggest that the antibiotics eliminated the majority of bacterial flora in the gut.

Tracie LewisWe are excited to announce that Tracie Lewis has joined the CCCR’s Colorectal Cancer Prevention Network (CCPN).  In assuming the position of Community Outreach Director, Ms. Lewis has taken on some of Anne Sinclair's and Annie Thibault’s former responsibilities pertaining to oversight of the outreach and development efforts.  Ms. Thibault will assume new responsibilities as CCPN Director, overseeing overall administration of the Network while continuing many of her current activities working alongside Ms. Lewis and Navigation Services Director Renay Caldwell.

Prior to joining the CCPN, Ms. Lewis was the State Health Systems Manager in South Carolina for the American Cancer Society, where she was employed for 17 years.  She received a Bachelor of Arts Degree in Biology from the College of Charleston, and a Master’s Degree in Exercise Science from the Arnold School of Public Health at the University of South Carolina.  She has worked extensively with state agencies, health insurers, and quality improvement networks to increase breast, cervical, and colorectal cancer screening through implementation of evidence-based practices.  Ms. Lewis currently serves on the Cancer Control Advisory Council for the South Carolina Department of Health and Environmental Control, and the Coordinating Council for the South Carolina Cancer Alliance.  She also serves on the Alliance’s Colorectal Cancer Workgroup.

These changes in team structure reflect important growth and expansion of the CCPN over the past few years.  It is our hope that the reach and impact of the Network will increase with regard to colorectal cancer education, awareness, and screening throughout South Carolina.

Recently, the Duke Endowment released its Annual Report for 2016, entitled Working Upstream, which highlighted the Endowment’s philanthropic efforts for the year.  One of the featured programs in the Report is the Center for Colon Cancer Research’s screening program.  The Duke Endowment awarded the CCCR’s statewide Colorectal Cancer Prevention Network $450,000 to further its efforts to provide colorectal cancer screening to uninsured and medically underserved individuals who may not have otherwise had the opportunity to receive this life-saving screen.  You can read more about the CCCR’s efforts to “Fight Cancer through Screening” in the Healthcare section of the Report, which can be accessed at
