SEER*Explorer Revision History

Below are a list of updates made to the data in the SEER*Explorer application.

Aug 9 2021

  • The survival by survival time and conditional survival estimates presented for stage specific cancer estimates presented the wrong year range of 2000-2017. The year range has been corrected to 2004-2017.

Jul 12 2021

  • The confidence intervals presented for the annual survival rates under survival recent trends were incorrect. The estimates have been corrected.

Apr 23 2021

  • The age-adjusted prevalence percentages presented for age groups smaller than 'All Ages' were not properly age-adjusted to the 2000 U.S. Standard population. The estimates have been corrected.

Apr 15 2021

  • The application was updated with incidence, survival, prevalence and lifetime risk estimates based on the SEER November 2020 submission.
  • Subtypes for Brain and Other Nervous System and Non-mailgnant Brain and Other Nervous System were added to the application based on the new SEER Brain/CNS Recode.
  • Starting with the November 2020 data submission, SEER now uses "Behavior code ICD-O-3" rather than the "Behavior recode for analysis" field in SEER*Stat and any published statistics. For more information, please see Behavior Variable Changes.
  • Conditional survival estimates were added for a majority of the available cancer sites.

Feb 10 2021

  • A new option was added to the Choose a Statistic to Explore options, Incidence and Mortality Comparison, which allows users to dispaly SEER Incidence and U.S. Mortality series on several of the existing graph types.

Sep 14 2020

  • The application was updated to include mortality estimates through 2018.
  • Delay-adjusted rates, when available, are the default rate type shown for SEER Incidence statistics.

Apr 15 2020

  • The application was updated with incidence, survival, mortality, prevalence and lifetime risk estimates based on the SEER November 2019 submission.
  • A new user-interface for the application is also part of this release.

Apr 15 2019

  • The application was updated with incidence, survival, mortality, prevalence and lifetime risk estimates based on the SEER November 2018 submission.
  • Statistics for several subtypes of larger cancer groupings including:
    • Breast Cancer
    • Esophagus Cancer
    • Lung and Bronchus Cancer
    • Thyroid Cancer
  • Charts for complete and limited-duration prevalence were added to the application.
  • Charts for 5-year recent rates were added for incidence and mortality.

Apr 16 2018

  • The application was updated with incidence, survival, mortality and lifetime risk estimates based on the SEER November 2017 submission.
  • Survival Trends charts were added to the application.
  • Charts for lifetime risk estimates were added to the application.
  • Relative survival for Asian/Pacific Islanders and Hispanic ethnicities were added to the five-year survival and survival by time since diagnosis charts.

Dec 1 2017

  • The user interface was updated based on feedback from usability testing.

May 18 2017

  • The relative survival estimates available under Survival->5-year survival were corrected. Previous estimates were cause-specific survival estimates. The estimates are now relative survival estimates.

Apr 14 2017

  • The application was updated with incidence, survival and mortality estimates based on the SEER November 2016 submission.

Apr 15 2016

  • The application was released with incidence and mortality estimates based on the SEER November 2015 submission.
