Starting January 1, 2014, only one database for diagnosis years 2010 and forward is available and is referred to as the “Hematopoietic and Lymphoid Neoplasm Database”. The consolidated manual and database include changes from 2010, 2012 and 2014. Earlier versions (2010 and 2012) are no longer available.

Comparison documents have been developed to identify the differences between the 2010, 2012 and 2014 changes of the Hematopoietic manual and database. These documents are meant to be a guide for registrars to how their data may have changed over time. Included with the rules, under the 2014 section in the second document below, is a column that comments on possible changes to incidence. Most of the changes will not affect incidence. There is an explanation of how and what to review where incidence may be affected.

Note: NCI SEER is not requiring review of data already collected based on these documents. If you have any questions, please Submit a question to SEER and choose "Hematopoietic Rules" as the subject.
