Higher Intake of Plant Protein Compared to Animal Protein Associated with Lower Mortality
Jiaqi Huang and Demetrius Albanes in the Metabolic Epidemiology Branch analyzed the dietary intake of over 400,000 participants from the NIH-AARP Diet and Health Study and found that greater intake of plant protein rather than animal protein was associated with lower overall and cardiovascular disease mortality.

Low Dose Ionizing Radiation Shown to Cause Cancer in Review of 26 Studies
Amy Berrington and colleagues conducted a systematic bias assessment and meta-analysis of 26 studies of low dose ionizing radiation. In a JNCI monograph published July 2020, they report a dose-response and statistically significant cancer risk for solid tumors and leukemia.

Genetic Architecture Study of 14 Cancers Describes Contribution of Common Variants
Montserrat García-Closas and colleagues at Johns Hopkins University and multiple consortia for 14 cancers showed that the utility of polygenic risk scores can vary widely depending on cancer type.
-
Resources from Radiation Epidemiology & Dosimetry Course Now Available
Video recordings and slides from the 2019 Radiation Epidemiology and Dosimetry Course are available online. The course covers the fundamentals of the health effects of radiation exposure, including methods of exposure assessment, and key findings from the latest studies of medical, occupational, and environmental radiation exposures.

2020 Virtual AACR Annual Meeting Features DCEG Research
Investigators and fellows presented their research and engaged virtually at the annual scientific meeting of the American Association for Cancer Research (AACR).

Artificial Intelligence Dual-Stain Approach Improved Accuracy, Efficiency of Cervical Cancer Screening
Nicolas Wentzensen and colleagues developed a computer algorithm to improve the accuracy and efficiency of cervical cancer screening compared with cytology, the current standard for follow-up of women who test positive with primary HPV screening. The new approach has clear implications for clinical care.

Robert Hoover Retires Leaving a Legacy of Cancer Epidemiology Research
In June 2020, Dr. Robert Hoover, Director of the Epidemiology and Biostatistics program, retired from the Division of Cancer Epidemiology and Genetics after a remarkable 48 years of service to the National Cancer Institute.

Nondaily and Low-Intensity Smoking Associated with Increased Risk of Death
Maki Inoue-Choi and collaborators found that nondaily smoking increases risk of death from any cause, compared to both former smokers and never smokers.
-
GWAS of Breast Cancer Subtypes Improves Understanding of Genetic Risk
Montserrat Garcia-Closas and colleagues report findings from a new genome-wide association study (GWAS) for breast cancer identifying 32 novel susceptibility loci. Importantly, this study reveals genetic risk for breast cancer subtypes and expands the potential for the development of subtype-specific polygenic risk scores.

HPV 35 Infection and Associated Cervical Precancer More Common Among Women of African Ancestry
Maisa Pinheiro, Julia Gage, and Lisa Mirabello in the Clinical Genetics Branch find African American women have more HPV 35 infections and HPV 35-associated cervical precancers than women of other races/ethnicities. Genomic analysis also revealed an association with the HPV 35 A2 sublineage and precancer/cancer in women of African ancestry. The highly-effective HPV vaccine covers seven oncogenic HPV types, but does not currently include HPV 35, therefore results from this study warrant further investigation on whether the addition of HPV 35 could provide better protection against cervical precancer for women in Africa or of African ancestry.

HPV Genotype Natural History and Implications for Cervical Cancer Screening
In a study of 11,573 HPV-positive women, Maria Demarco, Ph.D., M.P.H., et al., found HPV type and persistence are the major predictors of progression to cervical precancer. At a minimum, HPV16 is clinically important, and dividing the other HPV types into three risk-groups is worth considering. These findings were published in the journal EClinicalMedicine on April 24, 2020.

Gastrointestinal Cancers Global Burden Expected to Rise
Katherine McGlynn and Christian Abnet in the Metabolic Epidemiology Branch, in collaboration with the International Agency for Research on Cancer, examined the global burden of the five major types of gastrointestinal cancer, which include those of the stomach, liver, esophagus, pancreas, and colorectum.
