P1.01-15 - ROS1-Rearranged Non-Small Cell Lung Cancer Is Associated with High Rate of Venous Thromboembolism: Analysis of The METROS Trial (ID 12287)
16:45 - 18:00 | Author(s): Federico Cappuzzo
- Abstract
Background
Patients with lung cancer are at increased risk for venous thromboembolism (VTE) and 8% to 15% of patients with advanced non-small-cell lung cancer (NSCLC) experience a VTE event during the course of their disease. The incidence of VTE in molecularly defined NSCLC is still unknown. However, emerging data suggests that patients harbouring ALKrearrangements are at increased risk of VTE. In light of the high amino-acid sequence and structural homology with ALK protein, we undertook this study to determine the incidence of VTE in patients with ROS1-rearranged NSCLC.
a9ded1e5ce5d75814730bb4caaf49419 Method
The METROS trial is a multicentre prospective phase II study designed to assess efficacy, safety and tolerability of Crizotinib in pre-treated metastatic NSCLC with METamplification or METexon 14 mutation or ROS1rearrangement. ROS1-rearranged patients enrolled within cohort A and expansion cohort of the trial were evaluated in this analysis.

Among 48 patients with ROS1-rearranged lung adenocarcinomas (median [range] age 50 [28-82]); 17 males [35.4%] and 31 females [64.5%]; PS 0-1 [95.8%], 2 [4.2%]; 21 current/former smokers [43.75], 27 never smokers [56.25]) , 20 (41.6%) had at least one VTE event. VTE events consisted in pulmonary embolism (PE) in 11 patients (55%), deep vein thrombosis (DVT) in 11 patients (55%), renal vein thrombosis in 2 patients (10%). Seven patients (35%) had ≥ 1 VTE event. Patients with VTE were more likely to be older than 65 years (P = 0.029). No other associations between clinical characteristics and development of VTE were observed. The occurrence of VTE was not associated with overall survival.
8eea62084ca7e541d918e823422bd82e Conclusion
The incidence of VET is 3- to 5-fold higher in patients harbouring ROS1-rearrangment than previously observed for the general NSCLC population. Whether molecular profile of NSCLC should be incorporated into a risk-stratification tool and decision-making algorithm for VTE diagnosis, prophylaxis and treatment remains to be determined prospectively.

P1.01-53 - Bone Metastases and Efficacy of Immunotherapy in Patients with Pretreated Advanced Non-Small-Cell Lung Cancer (NSCLC) (ID 11980)
16:45 - 18:00 | Author(s): Federico Cappuzzo
- Abstract
Background
Approximately 40% of NSCLC patients develop bone metastases (BoM). Bone has active functions in regulating immune system. To date, no trial evaluated the role of BoM in modulating response to immunotherapy. Aim of the present study was to investigate whether presence of BoM impact on immunotherapy efficacy.
a9ded1e5ce5d75814730bb4caaf49419 Method
Two different cohorts of pretreated NSCLC patients (cohort A: Non-squamous; cohort B: Squamous) were evaluated for nivolumab efficacy in terms of objective response rate (ORR), progression free survival (PFS), and overall survival (OS) according to presence or absence of BoM. All patients received nivolumab at standard dose of 3 mg/kg every 2 weeks within the Italian Expanded Access Program.
4c3880bb027f159e801041b1021e88e8 Result
Cohort A accounted for 1588 patients with non-squamous NSCLC: 626 (39%) with (BoM+) and 962 (61%) without BoM (BoM-). Cohort B accounted for 370 patients with squamous histology: 102 BoM+ (32%) and 251 BoM- (68%). In Cohort A, BoM+ had a significantly lower ORR (12% versus 34%; p < 0.0001), shorter PFS (2.0 versus 4.0 months, p < 0.0001) and shorter OS (7.4 versus 15.3 months, p <0.0001). In cohort B, BoM+ had significantly lower ORR (15% versus 22%; p < 0.04), shorter PFS (2.7 versus 5.4 months, p <0.0001) and shorter OS (5.0 versus 10.9 months, p <0.0001). Presence of BoM negatively affected outcome irrespective of PS (OS cohort A: PS-0 BoM+ 12.0 versus 20.9 months in PS-0 BoM-, p<0.0001; OS cohort B: PS-0 BoM+ 5.8 versus 16.4 months in PS-0 BoM-, p<0.0001). Multivariate analysis confirmed that presence of BoM independently associated with higher risk of death with HR 1.64 and HR 1.78, for Cohort A and B, respectively.
8eea62084ca7e541d918e823422bd82e Conclusion
Our results, the first assessing BoM in patients treated with immunotherapy, suggested that BoM predict lower efficacy of immunotherapy. BoM should be included as stratification factor in clinical trials.
