The certificate will be sent to the email address provided at the time of registration. If you have questions about ESA accreditation for Infectious Agents and Cancer Epidemiology Research webinars, please email firstname.lastname@example.org.
Infections are established etiologic factors in several cancers and contribute significantly to the global cancer burden. In 2008, it was estimated that 16.1% of newly diagnosed cancers were attributable to infections. The translational potential for this area of research is significant, as the identification of infections associated with cancers may lead to interventions such as treatment or vaccines to prevent associated cancers. As discussed in a blog post by NCI, DCCPS, EGRP, epidemiologic studies on the interplay of infectious agents and cancer induction could play important roles in answering both old and new questions, which could augment current knowledge and open new areas of research. Understanding the role of infectious agents in cancer may result in discoveries that could lead to better diagnosis, prevention, and treatment of cancers, particularly in resource-poor areas.

Past Topics and Speakers
The Cervical Microbiome in HPV-associated Dysplasia
2:00 p.m. to 3:00 p.m. ET
Cervical cancer is the fourth most common female malignancy worldwide. Approximately 90% of cervical cancer deaths occur in low- and middle-income countries (LMIC), especially in sub-Saharan Africa. HPV has been established as the necessary etiological agent of cervical cancer, but it is an insufficient cause of the disease. HPV infection is common, yet only a small proportion develops into precursor lesions. It has recently been suggested that abnormal cervico-vaginal microbiota may play an important role in the development of cervical dysplasia and cervical cancer. These microbiota are thought to prevent effective HPV clearance. In her presentation, Dr. Uhlemann reviewed recent advances in the field of microbiome and HPV research.
Speaking with Microbes: The Oral Microbiome in Relation to Pancreatic Cancer Risk in African Americans
2:00 p.m. to 3:00 p.m. ET
Pancreatic cancer is the fourth most common cause of cancer death in the U.S. and incidence is increasing. African Americans have the highest incidence and mortality from pancreatic cancer of any racial/ethnic group in the U.S. Poor oral health has been implicated as a risk factor for pancreatic cancer and African Americans are reported to have worse oral health profiles than other racial/ethnic groups in the U.S., largely due to socioeconomic disadvantage and racial discrimination in the health care system, which can reduce access to preventive oral health care. An increased pancreatic cancer risk has been consistently associated with periodontal disease or tooth loss, which in turn correspond with changes in the oral microbiota—the community of microorganisms, including bacteria, fungi, viruses, and archaea, that reside within the oral cavity. This presentation explored the role of oral microorganisms in pancreatic cancer risk and disparities.
Accelerated Control of Cervical Cancer in a Resource Limited Setting
3:00 p.m. to 4:00 p.m. ET
Cervical cancer remains one of the few cancers that could be globally controlled, given the advanced understanding of its cause (human papillomavirus or HPV infection), and the development of prevention methods including HPV vaccines and HPV screening tests. Testing for HPV is now the preferred method for cervical cancer screening. An affordable screening strategy includes self-sampled HPV testing, with the risk of precancer provided by a combination of HPV typing and AI-assisted visual evaluation of the cervical appearance. In this webinar, Dr. Schiffman discussed the promise of this approach for resource-limited settings.
Dr. Mark Schiffman is an expert in using molecular epidemiologic research to address cancer health disparities. He has conducted HPV and cervical cancer research for more than 35 years and has received numerous awards and special honors for his work in molecular epidemiology. Dr. Schiffman is currently the co-Principal Investigator of “Accelerated Control of Cervical Cancer,” a research initiative of the Cancer Moonshot.
Helicobacter pylori and Colorectal Cancer: What Is the Association?
Meira Epplein is a cancer epidemiologist who studies modifiable risk factors in underserved populations, with a focus on the association of infection and cancer. She is Co-Leader of the Cancer Control and Population Sciences Program at Duke Cancer Institute and Associate Professor of Population Health Sciences in the Duke University Medical Center. Dr. Epplein’s research program is centered around the bacteria Helicobacter pylori, a spiral, gram-negative bacterium that infects approximately 50% of the world’s population and is the single leading carcinogenic infectious agent. Her research seeks to understand the heterogeneity of H. pylori, to determine the most toxigenic forms of the bacteria in order to identify the highest risk populations to be targeted for antibiotic therapy, which has been shown to be effective for risk reduction. At the same time, she is committed to furthering understanding of the co-factors involved in both H. pylori-associated disease risk and benefit. Dr. Epplein has three large NIH-funded grants to explore the epidemiology of H. pylori heterogeneity, including an R01 to further investigate, in a large consortium of prospective cohorts across the United States, the novel finding of host immune response to H. pylori protein-specific antibodies and the risk of colorectal cancer. She is also PI of the pilot study, DISH: The Durham Initiative for Stomach Health, which partners with Durham, North Carolina community members to educate and screen for H. pylori among high-risk individuals and to more finely characterize the prevalence of infection with H. pylori locally and the opportunities for targeted eradication therapy.
Understanding Mechanisms of HIV Persistence During Antiretroviral Therapy (ART)
Mary Kearney, Ph.D.
Head, Translational Research Unit
HIV Dynamics and Replication Program
Center for Cancer Research
National Cancer Institute
Dr. Mary Kearney conducts research on the emergence of HIV drug resistance, the persistence of HIV during antiretroviral treatment (ART), and the sources of rebound viremia after stopping ART. Her studies—in collaboration with colleagues in the HIV Dynamics and Replication Program in NCI’s Center for Cancer Research (CCR)—have demonstrated that a diverse population of HIV-infected cells persist during ART, that some infected cells proliferate despite ART, and that residual viremia during ART can result from viral expression from these cells. Dr. Kearney heads the Translational Research Unit in CCR, which aims to understand the genetics, evolution, and persistence of HIV and to design new approaches towards targeting and killing HIV-infected cells.
Dr. Kearney presented on mechanisms of HIV persistence during Antiretroviral Therapy (ART).

Hepatitis B Is the Major Etiology of Liver Cancer: Is a Cure Possible? Is It Necessary?
Timothy M. Block, Ph.D., is President and Co-founder of the Hepatitis B Foundation; its research arm, the Baruch S. Blumberg Institute; and the Pennsylvania Biotechnology Center. His work, with Baruch S. Blumberg, Anand Mehta, and Raymond Dwek, pioneered the use of glycoproteomics for detection of biomarkers of liver cancer, leading to the use of Golph2/GP73 and core fucosylated serum proteins as risk stratifiers for liver cirrhosis and hepatocellular carcinoma. His work with Ying Su led to using “microDNA” detected in the urine as a cancer marker. More recently, he and his colleagues (Ju-Tao Guo, Hai-Tao Guo, and Andy Cuconati) have identified small molecule inhibitors of hepatitis B virus, which are in clinical phase human testing today.
He is the scientific co-founder of several life sciences companies, co-inventor on 20 issued patents and 23 applications, co-author on more than 240 scholarly papers, and was named a “Visionary in Hepatitis” by the World Hepatitis Alliance in 2017. He was elected into the U.S. National Academy of Inventors and was awarded an Honorary Degree from the Bulgarian Academy of Medicine. He is Adjunct Professor at Geisinger Commonwealth School of Medicine and the University of Pennsylvania School of Medicine.
