| Abstract | ||
| Background: Multiple myeloma (MM) is a blood cancer caused by uncontrolled plasma cell growth, leading to protein buildup, organ damage. CD56, a cell adhesion molecule, is common in MM cells, but its prognostic role is debated. This study aimed for early prediction of response to therapy & outcome of patients with multiple myeloma expressing CD 56 correlated with other prognostic factors. Methods: In the prospective cohort study conducted at Zagazig University Hospitals, 30 newly diagnosed chemotherapy-naïve MM patients were enrolled. CD56 expression in bone marrow plasma cells was evaluated, dividing the patients into CD56-positive CD56-negative groups. Clinical, laboratory, and treatment parameters were evaluated and compared between the groups. Results: CD56 expression was detected in 60% of the patients. CD56-positive patients demonstrated significantly higher red blood cell counts (4.49 ± 0.33 vs. 4.01 ± 0.28 ×10⁶/µL; P = 0.0003), hemoglobin levels (10.31 ± 0.68 vs. 9.01 ± 0.32 g/dL; P < 0.0001), and platelet counts (194.11 ± 44.08 vs. 125.67 ± 15.08 ×10³/µL; P = 0.0001). Conversely, CD56-negative patients had significantly lower serum creatinine (1.79 ± 0.42 vs. 2.77 ± 0.86 mg/dL; P = 0.0034) LDH levels (315.56 ± 28.04 vs. 398.58 ± 68.1 U/L; P = 0.0019). Conclusion: CD56 expression has been shown to correlate with better hematological parameters, less disease burden and longer survival in MM patients. This CD56 negative patients present more aggressive disease features and may require different therapeutic approaches. These findings suggest a possible role for CD56 in stratifying risk and personalized treatment approaches for MM. | ||
