Öğe Real-world data on efficacy and safety of first-line alectinib treatment in advanced-stage, alk-positive non-small-cell lung cancer patients: A turkish oncology group study(Atypon, 2022) Hızal, Mutlu; Bilgin, Burak; Paksoy, Nail; Kılıçkap, Saadettin; Atcı, Muhammed Mustafa; Kahraman, Seda; Ayhan, Murat; Tural, Deniz; Yaman, Şebnem; Kutlu, Yasin; Korkmaz, Mustafa; Aksoy, Asude; Arak, Hacı; Korkmaz, Taner; Ak, Naziye; Akdeniz, Nadiye; Sakin, Abdullah; Fulden Yumuk, PerranAims: In this multicenter study, the authors aimed to determine the real-life efficacy and safety of first-line alectinib. Materials & methods: This retrospective trial included advanced-stage, ALK-positive non-small-cell lung cancer patients who were treated with first-line alectinib in terms of ALK-tyrosine kinase inhibitors, regardless of previous chemotherapy. The co-primary end points were progression-free survival both for all patients and for the treatment-naive population. The secondary end points were overall response rate, overall survival, rate of CNS progression and safety. Results & conclusion: A total of 274 patients (n = 177 for treatment-naive patients) were enrolled in the study. The median progression-free survival was 26 and 28.8 months for all patients and the treatment-naive group, respectively. The overall response rate, CNS progression rate and 1-year overall survival ratio were 77.9, 12.4 and 77%. Alectinib is a highly effective therapy with a favorable safety profile.
