Abstract

Objective: This study aimed to retrospectively evaluate the efficacy, safety, and survival outcome of single-agent ibrutinib therapy in chronic lymphocytic leukemia patients. Materials and Methods: A total of 136 patients (mean age ± standard deviation: 64.6±10.3 years, 66.9% males) who had received at least one dose of ibrutinib were included in this retrospective multicenter, noninterventional hospital-registry study conducted at 33 centers across Turkey. Data on patient demographics, baseline characteristics, laboratory findings, and leukemia-cell cytogenetics were retrieved. Treatment response, survival outcome including overall survival (OS) and progression-free survival (PFS), and safety data were analyzed. Results: Overall, 36.7% of patients were categorized as Eastern Cooperative Oncology Group (ECOG) class 2-3, while 44.9% were in Rai stage 4. Fluorescence in situ hybridization revealed the presence of del(17p) in 39.8% of the patients. Patients received a median of 2.0 (range: 0-7) lines of pre-ibrutinib therapy. Median duration of therapy was 8.8 months (range: 0.4-58.0 months). The 1-year PFS and OS rates were 82.2% and 84.6%, respectively, while median PFS time was 30.0 (standard error, 95% confidence interval: 5.1, 20.0-40.0) months and median OS time was 37.9 (3.2, 31.5-44.2) months. Treatment response (complete or partial response), PFS time, and OS time were better with 0-2 lines versus 3-7 lines of prior therapy (p

Özet

Amaç: Kronik lenfositik lösemi hastalarında tek ajan ibrutinib tedavisinin etkinliğini, güvenliğini ve sağkalım sonuçlarını geriye dönük olarak değerlendirmek. Gereç ve Yöntemler: Otuz üç merkezde yapılan bu retrospektif, çok merkezli, girişimsel olmayan hastane kayıt çalışmasına en az bir doz ibrutinib uygulanan 136 hasta (ortalama ± standart sapma yaş 64,6 10,3, % 66,9’u erkek) dahil edildi. Hastaların demografik verileri, bazal karakteristikleri, laboratuvar bulguları, lösemi hücre sitogenetiği ile ilgili veriler kaydedildi. Tedavi yanıtı, genel sağkalım (OS), progresyonsuz sağkalım (PFS) ve güvenlik verileri analiz edildi. Bulgular: Hastaların %36,7’sinde ECOG 2-3, % 44,9’u Rai evre 4 idi. FISH ile hastaların %39,8’inde del(17p) varlığını gösterdi. Hastalar medyan 2 (0 ila 7 arasında) sıra pre-ibrutinib tedavisi aldı. Medyan tedavi süresi 8,8 aydı (0,4-58 ay). Bir yıllık PFS ve OS oranları sırasıyla %82,2 ve %84,6, medyan (SE, %95 güven aralığı) PFS süresi 30 (5,1, 20-40) ay ve OS süresi 37,9 (3,2, 31,5-44,2) aydı. Tedavi yanıtı (CR veya PR), PFS ve OS süreleri; ibrutinib öncesi 3-7 basamak tedaviye karşı 0-2 basamak tedavi alanlarda (p
