Abstract

Objective: The soluble urokinase plasminogen activator receptor (suPAR) is a soluble form of the urokinase plasminogen activator receptor expressed in various immune and cancer cells. The levels of suPAR have been demonstrated to correlate with prognosis in various cancers. This study was intended to investigate serum suPAR levels and their effect on prognosis in patients with acute myeloid leukemia (AML).Materials and Methods: Thirty newly diagnosed patients with AML and 29 healthy individuals were enrolled. Serum suPAR levels were analyzed by enzyme-linked immunosorbent assay.Results: Serum suPAR levels were significantly higher in patients with AML than in healthy individuals (9±5.9 ng/mL and 2.4±1.4 ng/mL, respectively; p<0.001). Positive correlation was determined between suPAR levels and white blood cell counts (p<0.01). Serum suPAR levels were lower in patients who achieved complete response than in patients not achieving complete response (5.5±2.2 ng/mL and 12±6.6 ng/mL, respectively; p<0.001). The median overall survival was longer in patients with serum suPAR levels below 6.71 ng/mL than in those with serum suPAR levels above 6.71 ng/mL (12.6±13.2 months and 1.71±0.6 months, respectively; p=0.02). Multivariate Cox regression analysis showed that suPAR had independent prognostic value (95% confidence interval: 1.029-6.259; p<0.05) in AML. Conclusion: Serum suPAR levels can be used as a prognostic marker in AML

Özet

Amaç: Solubl ürokinaz plazminojen aktivatör reseptörü (süPAR) çeşitli immün sistem ve kanser hücrelerinde eksprese edilen ürokinaz plazminojen aktivatör reseptörün çözünür formudur. Çeşitli kanserlerde süPAR düzeyinin prognoz ile ilişkili olduğu gösterilmiştir. Bu çalışmada akut miyeloid lösemili (AML) hastalarda süPAR düzeyi ve prognoz üzerine olan etkisinin araştırılması planlandı. Gereç ve Yöntemler: Çalışmaya yeni tanı almış 30 AML'li hasta ve 29 sağlıklı birey dahil edildi. Serum süPAR düzeyi enzyme-linked immunosorbent assay yöntemi ile analiz edildi. Bulgular: Serum süPAR düzeyi AML'li hastalarda sağlıklı bireylere göre önemli derecede daha yüksek tespit edildi (9±5,9 ng/mL, 2,4±1,4 ng/mL, sırasıyla, p<0,001). süPAR düzeyi ile lökosit sayısı arasında pozitif bir korelasyon izlendi (p<0,01). Serum süPAR düzeyi, tam remisyona giren hastalarda tam remisyona girmeyen hastalara göre daha düşüktü (5,5±2,2 ng/mL, 12±6,6 ng/mL, sırasıyla, p<0,001). Toplam yaşam süresi, serum süPAR düzeyi 6,71 ng/mL'nin altında olan hastalarda, 6,71 ng/mL üstünde olanlara göre daha uzundu (12,6±13,2 ay, 1,71±0,6 ay, sırasıyla, p=0,02). AML'de çok değişkenli Cox regresyon analizi süPAR düzeyinin bağımsız prognostik değere sahip olduğunu gösterdi (%95 güven aralığı: 1,029-6,259; p<0,05).Sonuç: AML'li hastalarda serum süPAR düzeyi prognostik bir belirteç olarak kullanılabilir
