Test Code MPCDS mSMART, Plasma Cell Proliferative Disorder, FISH, Bone Marrow


Specimen Required


Only orderable as part of a profile. For more information see MSMRT / Mayo Algorithmic Approach for Stratification of Myeloma and Risk-Adapted Therapy Report, Bone Marrow.


Useful For

Aiding in the diagnosis of new cases of multiple myeloma or other plasma cell proliferative disorders as a part of a profile

 

Identifying prognostic markers based on the anomalies found

Testing Algorithm

This test is designed for diagnostic specimens from patients with multiple myeloma or other plasma cell proliferative disorders. If a request for testing has been submitted within 12 months of a complete and informative plasma cell proliferative disorder fluorescence in situ hybridization (FISH) study, the current test request will be cancelled.

  

For diagnostic samples, all probes in the initial panel will be evaluated if sufficient plasma cells are identified. The initial panel includes testing for the following the probes listed:

17p-, TP53/D17Z1

1q gain, TP73/1q22

14q32 rearrangement, IGH break-apart

8q24.1 rearrangement, MYC break-apart

-13/13q-, RB1/LAMP1

 

Based on the results from the initial panel, reflex testing may be performed to identify the following abnormalities using the probes listed:

t(11;14)(q13;q32), CCND1/IGH fusion

t(14;16)(q32;q23) IGH/MAF fusion

t(4;14)(p16.3;q32) FGFR3/IGH fusion

t(14;20)(q32;q12) IGH/MAFB fusion

t(6;14)(p21;q32) CCND3/IGH fusion

 

Hyperdiploidy will be evaluated and reported by flow cytometry as part of this evaluation and incorporated into the final interpretation. For samples with an unsuccessful flow evaluation for hyperdiploidy and with sufficient plasma cells, FISH testing for the following abnormalities will be performed using the probes listed:

+3/+7, D3Z1/D7Z1

+9/+15, D9Z1/D15Z4

 

For follow-up samples, the following probes will be evaluated if sufficient plasma cells are identified:

17p-, TP53/D17Z1

1q gain, TP73/1q22

8q24.1 rearrangement, MYC break-apart

 

If a diagnostic sample was uninformative for a probe set due to an insufficient number of plasma cells, attempts may be made to achieve results for the missing probe on a subsequent sample (if sufficient plasma cells are identified).
