Appendix R: ICD-O-3 Lymphatic and Hematopoietic Diseases - Subsequent Diagnoses

The CCR is concerned with identifying lymphomas and leukemias that are or might be treatment induced, usually as a result of chemotherapy plus radiotherapy or chemotherapy with alkylating agents.

The ICD-O-3 version of the hematopoietic primaries table is very different from the ICD-O-2 version in both format and medical understanding of these diseases. As a result, it is not possible to use the tables interchangeably. The first link indicated below, Definitions of Single and Subsequent Primaries for Hematologic Malignancies Based on ICD-O-3 Reportable Malignancies, Effective with Diagnoses 01/01/2001 and After, explains the reasoning that underlies the ICD-O-3 table.

From January 1, 2001 Forward

Use the ICD-O-3 table found in http://seer.cancer.gov/icd-o-3/hematopoietic_primaries.d03152001.pdf, if both diseases are diagnosed after January 1, 2001 or if a first diagnosis was prior to 2001, but a second diagnosis was after January 1, 2001.

Also review the following errata files.
