Effective September 1, 2021, for all cases diagnosed January 1, 2022 and forward.
As stated in the SEER online article, What is a Cancer Registry?, “cancer registries receive and collect data about cancer patients,” that is securely stored and submitted to other organizations, such as state Central Registries, SEER (Surveillance, Epidemiology, and End Results Program), NCDB (National Cancer Database), and other organizations. This information is then used by these organizations, such as “the SEER Program” which “receives the de-identified information - free of any identifiers of cancer patients” and “makes the data available to researchers and the public who are looking for cancer statistics such as incidence, mortality, survival, and prevalence. This information is disseminated in the form of fact sheets, reports, publications, media, research databases, and websites.” Cancer Registry, as with most things in life, requires changes to be made from time to time to keep up with advancements or to expand our knowledge as we continue to grow and learn new things every day.
Cancer registry guidelines and rules are written and developed by what the field calls, “Standard Setters.” Some of the organizations that are a part of this elite group are “The World Health Organization (WHO), the American Cancer Society (ACS), and the American Joint Committee on Cancer (AJCC).” At times, each of the organizations need to make changes to their guidelines, but it is important that they don’t all make changes at the same time. When one organization makes changes, it has to work smoothly with the requirements of other organizations. The last major changes in the world of cancer registry were in 2018. The large number of changes made trickled down and caused issues in other areas such as the release date of the registry software from the software vendors. This delay in turn delayed the processing of cancer abstracts and submissions to other organizations to be used in research. For 2021, we are seeing additional changes being made by some standard setters, but in a lesser degree.
This week we are continuing our review of some of the new rule changes to the Solid Tumor Rules. In the last two weeks we reviewed rule changes for head/ neck cancers and breast cancer. This week we are covering new changes being made to colon cancer.
