If there is an aberration in the patterns of February submissions in any particular year due to registry operational issues, then the delay-adjusted preliminary estimates may be biased. For example, this occurred in the February 2020 submission for cases diagnosed in 2018, due to the late arrival of registry software needed to code cases. This also occurred in the February 2022 submission for cased diagnosed in 2020, and was related to issues associated with case finding and consolidation during the pandemic. It should be noted that the true number of 2020 cases were also suppressed due the disruption of the medical care system, leading to delays in both the screening and diagnosis of cancers. The February 2023 submission for cases diagnosed in 2021 showed a pattern where selected registries had lower than expected case accrual based on their February 2023 data submission, so again preliminary estimates were not released. These issues led SRP to revise the prior methodology by including only registries that reached a specified completeness threshold in their February submission (see Selected Registries Based on Completeness). This new methodology was first employed for use with the February 2024 submission for Preliminary Estimates for cases diagnosed 2000-2022.

Registries that reached 95% completeness for 2022 for the February 2024 submission were included in this release: Connecticut, Greater Bay (San Francisco and San Jose), Seattle, Utah, New Jersey, Kentucky, Iowa, Hawaii, and Louisiana.

This is the first preliminary release where a subset of SEER registries that met a specific February submission completeness standard were included, and the first time preliminary estimates were released both on this web page and in SEER Explorer. In addition, race/ethnicity specific preliminary estimates were not released (even though they had been in the past), because SRP felt that for widespread release in Explorer, race/ethnicity specific estimates are not as reliable as those of for all races combined. This will be reevaluated in the future.
