Notes

9732 Multiple myeloma **Note 1:** The following sources were used in the development of this schema * SEER Extent of Disease 1988: Codes and Coding Instructions (3rd Edition, 1998) (https://seer.cancer.gov/archive/manuals/EOD10Dig.3rd.pdf) * SEER Summary Staging Manual-2000: Codes and Coding Instructions (https://seer.cancer.gov/tools/ssm/ssm2000/) * Collaborative Stage Data Collection System, version 02.05: https://cancerstaging.org/cstage/Pages/default.aspx * Chapter 82 *Plasma Cell Myeloma and Plasma Cell Disorder*, in the AJCC Cancer Staging Manual, Eighth Edition (2017) published by Springer International Publishing. Used with permission of the American College of Surgeons, Chicago, Illinois. **Note 2:** TNM data elements are not defined for this schema. TNM Stage Group is defined for multiple myeloma only (see Note 3) **Note 3:** The *Revised International Staging System (RISS)* is being used to stage plasma cell myeloma/multiple myeloma (9732). The following variables must be collected at the time of diagnosis for staging: * High Risk Cytogenetics [NAACCR Data Item #3857] * LDH Pretreatment Level [NAACCR Data Item #3932] * Serum Albumin Pretreatment Level [NAACCR Data Item #3930] * Serum Beta-2 Microglobulin Pretreatment Level [NAACCR Data Item #3931]
