title: Hysterectomy-corrected incidence rates of cervical and uterine cancers in Massachusetts, 1995 to 2010.
abstract: OBJECTIVE
  The aim was to provide ethnicity-specific incidence trends of cervical and uterine cancers uncorrected and corrected for the prevalence of hysterectomy in Massachusetts.
  
  
  METHODS
  We used incidence data of invasive cervical (International Classification of Diseases for Oncology, Third Edition: C53) and uterine cancer (International Classification of Diseases for Oncology, Third Edition: C54-C55) diagnosed from 1995 to 2010 from the Massachusetts Cancer Registry. Data from the Behavioral Risk Factor Surveillance Survey for Massachusetts were used to model the ethnicity-specific prevalence of hysterectomy. We standardized rates by the US 2000 population standard for the periods 1995 to 1998, 1999 to 2002, 2003 to 2006, and 2007 to 2010.
  
  
  RESULTS
  Depending on the period, corrected cervical cancer rates increased by 1.2 to 2.8, 5.6 to 8.3, and 3.2 to 8.2 per 100,000 person-years, and uterine cancer rates increased by 14.3 to 16.7, 14.8 to 29.3, and 6.7 to 15.4 per 100,000 person-years among white non-Hispanic women, black non-Hispanic women, and Hispanic women, respectively. Corrected estimated annual percentage changes increased for uterine cancer among black non-Hispanic women aged 60 years and older. Ethnic disparities between white non-Hispanic women and the other groups became smaller for uterine cancer and larger for cervical cancer after correction.
  
  
  CONCLUSIONS
  Corrections of cervical and uterine cancer rates for hysterectomy prevalence are important as ethnic disparities, age patterns and time trends of cervical and uterine cancer incidence rates change.
