Abstract

Objective: Significant developments occurred in the clinicalmanagement of acute lymphoblastic leukemia (ALL) in adults inrecent decades. However, treatment results are still not satisfactory,especially in routine practice. The objective of this study was toevaluate the general clinical features, treatment details, and outcomesof a large group of patients followed in multiple centers in Turkeywith a diagnosis of ALL.Materials and Methods: A retrospective analysis of the data ofpatients with ALL was made, the patients having been diagnosed andtreated between January 2003 and June 2017 by different protocols inthe hematology clinics of ten different centers. A total of 288 patients,aged between 17 and 76 years old, were included in the study. In thisretrospective multicenter analysis of patients with ALL, classificationof patients was performed based on treatment period, Philadelphiachromosome positivity, treatment regimen, and administration ofallogeneic hematopoietic stem cell transplantation (allo-HSCT).Results: The majority of cases were B-cell in origin, while 224 patientshad B-ALL and 64 of the patients had T-ALL. Median follow-upduration for all patients was 18.2 months (range: 0.03-161 months).Philadelphia chromosome positivity was determined in 49 patients(21.9%), and 54 patients (18.8%) were receiving allo-HSCT. Afterinduction chemotherapy, 219 patients (76.0%) achieved complete remission, 32 patients (11.2%) were evaluated as treatment refractory,and 37 patients (12.8%) were deceased. Median overall survivalwas 47.7 months (95% confidence interval: 36.1-59.2) and mediandisease-free survival was 23.4 months (95% confidence interval: 6.7-40.0) for all patients.Conclusion: Multicenter studies are extremely important for definingthe specific clinical features of a particular disease. The results of thisstudy will make a significant contribution to the literature as theyreflect real-life data providing valuable information about the TurkishALL patient profile.

Özet

Amaç: Son yıllarda erişkinlerde akut lenfoblastik löseminin (ALL) tedavi yönetiminde önemli gelişmeler meydana gelmiştir. Bununla birlikte, özellikle rutin uygulamada tedavi sonuçları hala tatmin edici değildir. Çalışmanın amacı, Türkiye’de birden fazla merkezde takip edilen geniş bir ALL hasta grubunun genel klinik özelliklerini, tedavi özelliklerini ve sağkalım sonuçlarını değerlendirmektir. Gereç ve Yöntemler: Ocak 2003 ile Haziran 2017 tarihleri arasında on farklı merkezdeki hematoloji kliniğinde tanı konulan ve farklı protokollerle tedavi edilen ALL hastalarının verilerinin retrospektif analizi yapıldı. Çalışmaya yaşları 17 ile 76 arasında değişen toplam 288 hasta dahil edildi. Bu çalışmada ALL’li hastalar tedavi periyoduna, Philadelphia kromozom pozitifliğine, tedavi protokolü ve allojenik hematopoetik kök hücre nakli (AHKHN) yapılıp yapılmamasına göre sınıflandırıldı. Bulgular: Olguların 224’ü B-ALL, 64’ü T-ALL idi. Tüm hastalar için ortanca takip süresi 18,2 ay (dağılım, 0,03-161 ay) idi. Philadelphia kromozomu (Ph+) pozitifliği 49 (%21,9) hastada saptandı ve 54 hastaya (%18,8) AHKHN yapıldığı izlendi. İndüksiyon kemoterapisinden sonra 219 hasta (%76) tam remisyona girdi, 32 hasta tedaviye refrakter (%11,2) olarak değerlendirildi, 37 hastada ise (%12,8) mortalite gözlendi. Ortanca genel sağkalım 47,7 ay (%95 güven aralığı: 36,1- 59,2) ve ortanca hastalıksız sağkalım tüm hastalar için 23,4 ay (%95 güven aralığı: 6,7-40,0) idi.Sonuç: Sonuç olarak, çok merkezli çalışmalar, belirli bir hastalığın spesifik klinik özelliklerini tanımlamak için büyük öneme sahiptir. Bu çalışmanın sonuçları, Türk ALL hasta profili hakkında değerli bilgiler sağlayan gerçek hayat verilerini yansıttığı için literatüre önemli bir katkı sağlayacaktır.
