Identification of BRCA1-Associated RING Domain 1 Mutation as a Novel Indicator for Constructing a Prognostic Nomogram...

Area of Science:

• Hematology
• Oncology
• Genetics

Background:

• The prognostic value of BRCA1-associated RING domain 1 (BARD1) in newly diagnosed multiple myeloma (NDMM) requires further definition.
• Multiple myeloma is a hematologic malignancy with complex genetic underpinnings.

Purpose of the Study:

• To investigate the prognostic significance of BARD1 gene mutations in NDMM patients.
• To develop a predictive model for overall survival (OS) and progression-free survival (PFS) in NDMM.

Main Methods:

• Retrospective analysis of 74 NDMM patients.
• Utilized Cox's proportional hazards model to construct a nomogram incorporating R2-ISS staging and BARD1 gene mutation status.

Main Results:

• BARD1 gene mutations and R2-ISS staging showed significant correlations with both OS and PFS (P < 0.01).
• The developed nomogram demonstrated excellent predictive performance for OS and PFS in both training and validation cohorts.

Conclusions:

• A nomogram integrating BARD1 gene status and R2-ISS staging effectively predicts NDMM prognosis.
• Findings may guide future research into targeted therapies for multiple myeloma based on genetic mutations.
