Cervical cancer trends in the United States: a 35-year population-based analysis.
ABSTRACT Abstract Purpose: To analyze trends in invasive cervical cancer incidence by age, histology, and race over a 35-year period (1973-2007) in order to gain insight into changes in the presentation of cervical cancer. Methods: Data from the nine Surveillance, Epidemiology, and End Results (SEER) registries that continuously collected information on invasive cervical cancer were analyzed for trends. Standardized to the 2000 U.S population, annual age-adjusted incidence rates were estimated by race and histologic subtype. Histologic subtype was classified into squamous, adenocarcinoma, and adenosquamous. Results: Overall incidence rates for invasive cervical cancer decreased by 54% over the 35 years, from 13.07/100,000 (1973-1975) to 6.01/100,000 (2006-2007), and the incidence rates declined by 51% and 70.2%, respectively, among whites and blacks. The incidence rates for squamous carcinoma decreased by 61.1% from 10.2/100,000 (1973-1975) to 3.97/100,000 (2006-2007). Incidence rates for adenosquamous cell carcinomas decreased by 16% from 0.27/100,000 (1973-1975) to 0.23/100,000 (2006-2007), and incidence rates for adenocarcinomas increased by 32.2% from 1.09/100,000 (1973-1975) to 1.44/100,000 (2006-2007). This increase in adenocarcinomas was due to an increase in incidence in white women; a decrease in incidence was observed for black women. Conclusions: Although marked reductions in the overall and race-specific incidence rates of invasive cervical cancer have been achieved, they mask important variation by histologic subtype. These findings suggest that alternatives to Pap smear-based screening, such as human papillomavirus (HPV) testing and HPV vaccination, need to be prioritized if adenocarcinomas of the cervix are to be controlled.

ABSTRACT: Screening for cervical cancer with DNA ploidy assessment by automated quantitative image cytometry has spread throughout China over the past decade and now an estimated 1 million tests per year are done there. Compared to conventional liquid based cytology, DNA ploidy has competitive accuracy with much higher throughput per technician. DNA ploidy has the enormous advantage that it is an objective technology that can be taught in typically 2 or 3 wk, unlike qualitative cytology, and so it can enable screening in places that lack sufficient qualified cytotechnologists and cytopathologists for conventional cytology. Most papers on experience with application of the technology to cervical cancer screening over the past decade were published in the Chinese language. This review aims to provide a consistent framework for analysis of screening data and to summarize some of the work published from 2005 to the end of 2013. Of particular interest are a few studies comparing DNA ploidy with testing for high risk human papilloma virus (hrHPV) which suggest that DNA ploidy is at least equivalent, easier and less expensive than hrHPV testing. There may also be patient management benefits to combining hrHPV testing with DNA ploidy. Some knowledge gaps are identified and some suggestions are made for future research directions.World journal of clinical oncology. 12/2014; 5(5):931-965.

ABSTRACT: Less-developed-region countries (LDCs) are seeing a rapid rise in cancer incidence owing to changing lifestyles, infections, environmental carcinogens and increasing longevity. LDCs have poor resources to deal with cancers, leading to high mortality rates. Investment in nationally implementable and sustainable cancer prevention and screening strategies would be more appropriate for LDCs. This Science and Society article outlines the burden of preventable cancers in selected LDCs and discusses evidence on cost-effective and widely implementable prevention and screening strategies.Nature reviews.
