A Snapshot of Cervical Cancer
Incidence and Mortality
Although cervical cancer incidence rates have declined 45 percent and mortality rates have declined 49 percent in the United States since 1980, the disease remains a serious health threat. Incidence rates in Hispanic women and American Indian/Alaska Native women are higher than in women from other racial/ethnic groups. Despite recent declines, mortality rates in African American women remain higher than women of any other racial/ethnic group in the United States. Cervical cancer mortality and incidence rates also vary with socioeconomic status and geographic location and cervical cancer screening rates vary across racial/ethnic, socioeconomic, and geographic groups.
Researchers have identified certain types of human papillomavirus (HPV) that are transmitted through sexual contact as the cause of essentially all cervical cancers. Cervical cancer is preventable and curable if detected early. Important strategies to reduce cervical cancer deaths include screening with the Papanicolaou (Pap) test or with both the Pap test and a DNA test for HPV (cotesting). Another strategy is use of the HPV vaccine, which prevents infection with the HPV types that cause most cervical cancers. Standard treatment options for cervical cancer include surgery, radiation therapy, and chemotherapy.
Assuming that incidence and survival rates follow recent trends, it is estimated that $1.3 billion1 will be spent on cervical cancer care in the United States in 2014.
NCI’s Investment in Cervical Cancer Research
To learn more about the research NCI conducts and supports in cervival cancer, visit the NCI Funded Research Portfolio (NFRP). The NFRP includes information about research grants, contract awards, and intramural research projects funded by NCI. When exploring this information, it should be noted that approximately half of the NCI budget supports basic research that may not be specific to one type of cancer. By its nature, basic research cuts across many disease areas, contributing to our knowledge of the underlying biology of cancer and enabling the research community to make advances against many cancer types. For these reasons, the funding levels reported in NFRP may not definitively report all research relevant to a given category.
Other NCI programs and activities relevant to cervical cancer include:
- The Centers for Population Health and Health Disparities are supporting transdisciplinary research on interactions of the social and physical environments, behavioral factors, and biologic pathways that determine health and disease in populations. One center is focused on understanding why cervical cancer incidence and mortality are higher in Appalachian Ohio and West Virginia than in other areas of the United States.
- The Division of Cancer Epidemiology and Genetics (DCEG) is conducting population and multidisciplinary research to discover the genetic and environmental causes of cancer and new approaches to cancer prevention, including studies addressing cervical cancer.
- The Breast and Gynecologic Cancer Research Group conducts and supports research on the prevention and early detection of breast, cervical, endometrial, and ovarian cancers.
- The Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) program is supporting multisite, coordinated, transdisciplinary research on cervical cancer screening to better understand how to improve the screening process, including recruitment, diagnosis, and referral for treatment. The cervical cancer project is comparing self-collection to provider-directed HPV primary screening; analyzing statewide cervical screening, diagnosis, and treatment failures; and comparing the effectiveness of alternative interventions.
- The Molecular Profiling-Based Assignment of Cancer Therapy for Patients With Advanced Solid Tumors (MPACT) trial is assessing whether choosing specific treatment options based on tumor mutations is more effective than standard cancer treatments. MPACT could identify patient subgroups that are likely to benefit from certain treatments and result in new treatments being developed quickly for some cancers.
- The phase III Radiation Therapy With or Without Chemotherapy in Patients With Stage I or Stage II Cervical Cancer Who Previously Underwent Surgery trial is examining whether patients treated with chemoradiotherapy after surgery live longer without any signs or symptoms of cancer compared with patients treated with radiation therapy alone after surgery.
Selected Advances in Cervical Cancer Research
- Genomic comparisons of normal tissue and cervical carcinomas identified several recurrent mutations in cervical carcinomas that suggest new strategies to combat this disease. Published December 2013. [PubMed Abstract]
- A vaccine used to treat women with high-grade precancerous cervical lesions triggers a robust immune response within cervical lesions, while conventional blood analysis detected only a modest immune response, suggesting that measuring responses directly in the lesions may be a more accurate way to evaluate therapeutic vaccines. Published January 2014. [PubMed Abstract]
- In a randomized clinical trial, women with advanced cervical cancer who were treated with bevacizumab and chemotherapy lived about 4 months longer than those who were treated with chemotherapy alone. Published February 2014. [PubMed Abstract]
- HPV types that cause most cervical cancers cause changes in the levels of small molecules called microRNAs in the infected cells and tissue, suggesting that these changes potentially could be used to diagnose or monitor the progression of cervical disease. Published March 2014. [PubMed Abstract]
