Abstract Introduction Patients with advanced non-small cell lung cancer (NSCLC) benefit from treatment with immune checkpoint inhibitors (ICIs). Biomarkers such as programmed death-ligand 1 (PD-L1), the tumor mutational burden (TMB) and the mismatch repair (MMR) status are used to predict the prognosis of ICIs therapy. Nevertheless, novel biomarkers need to be further investigated, and a systematic prognostic model is needed for the evaluation of the survival risks of ICIs treatment.Methods A cohort of 240 patients who received ICIs from the cBioPortal for Cancer Genomics was evaluated in this research. Clinical information and targeted sequencing data were acquired for analyses. The Kaplan-Meier plot method was used to perform survival analyses, and selected variables were then confirmed by a novel nomogram constructed by the “rms” package of R software.Results Seven percent of the NSCLC patients harbored ARID1A mutations, while 4% of the NSCLC patients harbored ARID1B mutations. Mutations in ARID1A and ARID1B were confirmed to be associated with sensitivity to ICIs. Patients harboring these mutations were found to have a better response to treatment (ARID1A: P=0.045; ARID1B: P=0.034) and prolonged progression-free survival (ARID1B: P=0.032). Here, a novel nomogram was constructed to predict the prognosis of ICIs treatment. Elevation of the TMB, enhanced expression of PD-L1 and activation of the antigen presentation process and cellular immunity were found to be correlated with ARID1A and ARID1B mutations.Conclusion ARID1A and ARID1B could serve as novel biomarkers for the prognosis and sensitivity to ICIs of advanced NSCLC.

e21198 Background: Venous thromboembolism is a frequent complication of non-small cell lung cancer (NSCLC) and is associated with a worse prognosis, a reduced quality of life, and increased healthcare costs. Immune checkpoint inhibitors (ICI) are revolutionizing the management of NSCLC, but little is known about their impact on thrombosis. This study aims to define the incidence and clinical relevance of thrombosis in NSCLC patients receiving these treatments. Methods: A retrospective multicentric cohort study including 593 patients from three centers in Canada and France was performed. The cumulative incidence of venous thrombotic events after ICIs was calculated, and the impact of these events on survival and response to treatment was determined. Finally, univariate log-rank tests were performed to identify thrombosis risk factors. Results: The incidence of venous thrombosis in the cohort was 9.9% for an incidence rate of 76.5 thrombosis per 1000 person-years, with most thromboses occurring rapidly after treatment initiation. Thrombosis was not correlated with overall survival, progression-free survival, or objective response to ICIs (summarized in the table below). Age ˂ 65 years old (HR = 1.66; 95 % CI = 1.00 – 2.82) and a delay of less than 12 months from diagnosis to the first ICI treatment (HR = 1.74; 95 % CI = 1.03 – 2.87) were associated with an increased risk of thrombosis. Tumors with PD-L1 > 1% were associated with more thrombosis in the first year since the beginning of therapy (HR = 3.06; 95 % CI = 1.19 – 4.76, p=0.015). Conclusions: This study suggests that the time distribution and incidence of thrombotic events in NSCLC patients treated with ICI are comparable to what is reported in other cohorts of patients treated with chemotherapy. In our cohort, thrombosis was not a prognostic factor for survival or response to therapy. Patient age < 65 and tumors with PD-L1 > 1% were associated to a higher risk of thrombotic events.[Table: see text]

BackgroundImmune checkpoint inhibitors (ICIs) have become a high-profile regimen for malignancy recently. However, only a small subpopulation obtains long-term clinical benefit. How to select optimal patients by reasonable biomarkers remains a hot topic.MethodsPaired tissue samples and blood samples from 51 patients with advanced malignancies were collected for correlation analysis. Dynamic changes in blood PD-L1 (bPD-L1) expression, including PD-L1 mRNA, exosomal PD-L1 (exoPD-L1) protein and soluble PD-L1 (sPD-L1), were detected after 2 months of ICIs treatment in advanced non-small-cell lung cancer (NSCLC) patients. The best cutoff values for progression-free survival (PFS) and overall survival (OS) of all three biomarkers were calculated with R software.ResultsIn 51 cases of various malignancies, those with positive tissue PD-L1 (tPD-L1) had significantly higher PD-L1 mRNA than those with negative tPD-L1. In 40 advanced NSCLC patients, those with a fold change of PD-L1 mRNA ≥ 2.04 had better PFS, OS and best objective response (bOR) rate. In addition, a fold change of exoPD-L1 ≥ 1.86 was also found to be associated with better efficacy and OS in a cohort of 21 advanced NSCLC cases. The dynamic change of sPD-L1 was not associated with efficacy and OS. Furthermore, the combination of PD-L1 mRNA and exoPD-L1 could screen better patients for potential benefit from ICIs treatment.ConclusionThere was a positive correlation between bPD-L1 and tPD-L1 expression. Increased expression of PD-L1 mRNA, exoPD-L1, or both in early stage of ICIs treatment could serve as positive biomarkers of efficacy and OS in advanced NSCLC patients.
