P1.01-104 - Survivals in ROS1-Rearranged Advanced Non-Small-Cell Lung Cancer Treated with First-Line Crizotinib (ID 1735)
09:45 - 18:00 | Author(s): Bin-Chao Wang
The c-ros oncogene 1 (ROS1)-rearranged non-small-cell lung cancer (NSCLC) can be treated effectively with crizotinib, a tyrosine kinase inhibitor (TKI) of anaplastic lymphoma kinase (ALK), ROS1, and mesenchymal-epithelial transition (MET). However, few studies have investigated on survivals in ROS1-rearranged advanced NSCLC patients treated with first-line crizotinib.Method
We retrospectively analyzed clinicopathological and survival data of ROS1-rearranged patients with advanced NSCLC treated with crizotinib between August 2013 and January 2019 at the Guangdong Provincial People's Hospital. ROS1 rearrangements were detected by Reverse Transcription-Ploymerase Chain Reaction(RT/PCR),Fluorescence in situhybridization (FISH), or Next-generation Sequencing (NGS) . Overall survival (OS) and progression-free survival (PFS) were compared between first-line crizotinib, chemotherapy followed by crizotinib and first-line chemotherapy without any subsequent targeted therapy.Result
Among totally 40 patients with ROS1-rearranged advanced NSCLC, 29 were treated with crizotinib (16 with first-line; 13 with second- or further-line), and 11 were not treated with crizotinib at data cutoff (April 4, 2019). Median OS was significantly prolonged in patients with first-line crizotinib (N=16) than those with first-line chemotherapy followed by subsequent crizotinib (N=9), not reached vs. 27.1 months, P=0.042. However, there was no significant difference in median PFS between the two groups, 16.3 vs. 5.7 months, P=0.054. Meanwhile, first-line crizotinib (N=16) was significantly superior to first-line chemotherapy without any subsequent targeted therapy (N=8) in both median OS (not reached vs. 9.1 months, P=0.024) and PFS (16.3 vs. 4.8 months, P=0.017).Conclusion
First-line crizotinib prolongs survivals than chemotherapy for patients with ROS1-rearranged advanced NSCLC.
