HPV Vaccine Protection Outweighs Additional Risk of Cervical Lesions Caused by Non-Preventable HPV Types
In a study published June 2022 in Lancet Oncology, Jaimie Shing, Ph.D., M.P.H., and colleagues observed that HPV types not targeted by the vaccine cause cervical lesions more frequently in vaccinated populations than in unvaccinated populations. However, the number of prevented cervical lesions was considerably greater than the number of additional lesions attributed to non-preventable HPV types, thus confirming the efficacy of the HPV vaccine for cervical cancer prevention.
this study is the first to observe and evaluate clinical unmasking following HPV vaccination. -
Oral Microbiome Linked to Lung Cancer Risk
A study from Emily Vogtmann, Ph.D., M.P.H., senior investigator in the Metabolic Epidemiology Branch, links the oral microbiome to lung cancer risk using data from three DCEG cohorts: the Agricultural Health Study, NIH-AARP Diet and Health Study, and the Prostate, Lung, Colorectal, and Ovarian Cancer Screening trial.

Validation of a Low-cost, Rapid HPV DNA Genotyping Test for Cervical Cancer Prevention
A key deliverable of the Cancer Moonshot initiative to Accelerate Cervical Cancer Control is a rapid, mobile, simple, and affordable HPV DNA typing assay for risk-based screening and management in resource-limited settings where routine screening is logistically and cost prohibitive. Drs. Kanan Desai, Mark Schiffman, Silvia de Sanjose, and colleagues in the Clinical Epidemiology Unit, Clinical Genetics Branch, in cooperation with Atila Biosystems scientists, guided the redesign of an existing test for this purpose.

Two Studies on Disinfection Byproducts in Drinking Water and Cancer Risk
Two studies from the Occupational and Environmental Epidemiology Branch, led by Drs. Laura Beane Freeman and Rena Jones, respectively, investigated the relationship between disinfection byproducts in drinking water and genetic factors for risk for bladder cancer and hormonal factors and risk for endometrial cancer.

Cancer Death Rates Among Black People Declined Over Time, but Remain Higher than Other Racial and Ethnic Groups
Wayne Lawrence, Dr.Ph.H., postdoctoral fellow in the Metabolic Epidemiology Branch, and Meredith Shiels, Ph.D., senior investigator in the Infections and Immunoepidemiology Branch report that from 1999 to 2019, rates of cancer deaths declined steadily among Black people in the United States. Nevertheless, in 2019, Black people still had considerably higher rates of cancer death than people in other racial and ethnic groups.

HPV 16 Variants Associated with Prognosis for Oropharyngeal Cancer
Human papillomavirus-driven oropharyngeal cancer (HPV-OPC), a type of throat cancer caused by oral HPV infection, is rapidly increasing in incidence in the US. This is the first study to sequence the HPV genome in a large number of HPV-OPC, and links HPV16 genetic variants to poorer patient survival. Median survival was 4 years for OPC patients with an HPV infection with one or more of eight specific viral genetic variants compared to 19 years for patients with infections without these variants.

Uterine Cancer Death Rates Rising, Highest Among Black Women in the United States
A study led by Dr. Megan Clarke in the Clinical Epidemiology Unit, finds mortality rates from uterine cancer have been rising in the United States from 2010 to 2017, and are highest among non-Hispanic Black women. The higher death rates are driven by rising incidence of aggressive subtypes of uterine cancer, which are more commonly diagnosed in non-Hispanic Black women.

Spectrum of Skin Cancer Risk Characterized for Solid Organ Transplant Recipients
In the largest cohort study to date of solid organ transplant recipients, Michael Sargen, M.D., and colleagues characterized the spectrum of risk for common and rare non-keratinocyte skin cancers. Key risk factors that may contribute to elevated risk are viruses, UV radiation exposure, and immunosuppression.

Study Suggests HPV Vaccine Would Prevent Most Cervical Cancers/Precancers Across Major U.S. Racial/Ethnic Groups
Investigators from the CDC, Biostatistics Branch, and Clinical Genetics Branch collaborated on a pooled analysis of human papillomavirus (HPV) genotype studies in the U.S. and showed that among major racial and ethnic groups, at least 84% of cervical precancers and 90% of invasive cancers were attributed to HPV types targeted by the 9-valent HPV vaccine. Among non-Hispanic Black women, a higher proportion of squamous cervical precancers were attributed to non-vaccine types, especially HPV 35.

Small Increases in Physical Activity Could Prevent Over 100,000 Deaths/Year
A research letter from Pedro Saint-Maurice, Ph.D., and Charles Mathews, Ph.D., in the Metabolic Epidemiology Branch and Barry Graubard, Ph.D., in the Biostatistics Branch, reported that if the adult population in the United States increased moderate-to-vigorous intensity physical activity by 10 minutes per day, more than 100,000 deaths per year could be prevented. Similar benefits were observed regardless of sex or racial and ethnic group.
