SSDI-HIGH RISK CYTOGENETICS

Introducing himagine’s Tumor Tip of The Week. Do you know the correct answer?

Scenario

Patient diagnosed with Plasma Cell Myeloma 04-18-2018.

Question:

What tests should we refer to in order to determine if high risk cytogenetics are present?

Answer:

High-risk cytogenetics consist of one or more of the following: del17p, t(4;14), or t(14;16).

Rationale:

This is a great example of when the information in a drop down in your registry software or the limited information in SEER*RSA is just not enough.  You must go to the source, the actual full SSDI Manual for clarification.  Site-Specific Data Item (SSDI) Manual Effective with Cases Diagnosed 1/1/2018 and Forward Published February 2019 Version 1.5 page 387 https://www.naaccr.org/SSDI/SSDI-Manual.pdf?v=1565354436

Tip:

Disregard other FISH tests being abnormal, currently the only cytogenetics we are reviewing can be found in AJCC Cancer Staging Manual, Eighth Edition American College of Surgeons. Chapter 82 *High-risk cytogenetics consist of one or more of the following: del17p, t(4;14), or t(14;16).
