Plasma plastin-3: A tumor marker in patients with non-small-cell lung cancer treated with nivolumab.

ABSTRACT: Plastin-3 (PLS3) is a circulating tumor cell marker associated with aggressive cancer phenotypes. The present study aimed to investigate the usability of plasma PLS3 concentration in assessing the diagnosis, prognosis and sensitivity to treatment in patients with non-small-cell lung cancer (NSCLC) treated with nivolumab. A total of 33 patients with recurrent or advanced NSCLC were treated with nivolumab, and 10 healthy volunteers were retrospectively enrolled. Plasma concentrations of PLS3 were determined by ELISA. Plasma PLS3 concentration in patients with NSCLC was significantly higher compared with that in healthy volunteers (median 7.64 ng/ml vs. 3.13 ng/ml, P<0.001). Univariate analysis indicated that PLS3 ?5.43 ng/ml was a predictor of partial response. Patients with PLS3 >8.55 ng/ml exhibited a poorer prognosis compared with those in the PLS3 ?8.55 ng/ml group. A high plasma PLS3 concentration was a predictor of poor overall survival. In conclusion, plasma PLS3 concentration was identified as a marker for the diagnosis, treatment sensitivity and prognosis in patients with NSCLC treated with nivolumab. Plasma PLS3 may be a clinically useful tumor marker in patients with NSCLC; future prospective studies may confirm these results and explore its use in other cancers.

Project description:Importance:Nivolumab and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are now the standard-of-care therapies in non-small cell lung cancer (NSCLC). Although EGFR-TKIs are well understood and have well-defined safety profiles, our experience with immune checkpoint inhibitors is still growing, particularly regarding the use of combinations of different classes of antitumor agents, including both the concomitant and sequential use of such agents. Objective:To determine whether nivolumab increases EGFR-TKI-associated interstitial pneumonitis (IP). Design, Setting, and Participants:A database study of 20 516 participants with NSCLC in the US Food and Drug Administration Adverse Event Reporting System (FAERS) database, performed between April 2015 and March 2017. Main Outcomes and Measures:We compared the incidence of EGFR-TKI-associated IP in patients receiving and not receiving nivolumab treatment. Results:The mean (SD) age of participants treated with EGFR-TKI, with and without nivolumab, was 64.4 (15.5) and 68.9 (11.8) years, respectively, and the proportion of men was 40.0% and 53.8%, respectively. Of the 20 516 participants with NSCLC, 985 cases (4.80%; 95% CI, 4.51-5.10) developed IP. Of 5777 patients treated with EGFR-TKI, 265 developed IP (4.59%; 95% CI, 4.06-5.16). Of 70 patients treated with both EGFR-TKI and nivolumab, 18 developed IP (25.7%; 95% CI, 16.0-37.6). The adjusted odds ratio for an interaction between EGFR-TKI and nivolumab was 4.31 (95% CI, 2.37-7.86; P < .001), suggesting the existence of an interaction. When we further stratified the patients by treatment with and without nivolumab, the odds ratio of EGFR-TKI-associated IP in cases with and without nivolumab treatment was 5.09 (95% CI, 2.87-9.03) and 1.22 (95% CI, 1.00-1.47), respectively. Conclusions and Relevance:We found a higher proportion of reports of IP for nivolumab in combination with EGFR-TKI vs treatment with either drug alone. Owing to the limitations of this study, the results warrant further confirmation. However, careful consideration should be given to the possibility of an increased risk of IP when EGFR-TKI is administered in combination with nivolumab, including concomitant and sequential use, and careful monitoring for IP is recommended.

Project description:ImportanceEvidence regarding real-world effectiveness of therapies for patients with advanced non-small cell lung cancer (NSCLC) whose tumors are resistant to platinum-based chemotherapy is lacking.ObjectiveTo compare the effectiveness of the immune checkpoint inhibitors atezolizumab (programmed cell death ligand 1 inhibitor) and nivolumab (programmed cell death 1 inhibitor) and the chemotherapy drug docetaxel in patients with advanced NSCLC resistant to platinum-based chemotherapy.Design, setting, and participantsThis comparative effectiveness study compared patients aged 18 years or older with advanced NSCLC who initiated atezolizumab, docetaxel, or nivolumab and who had previously been exposed to platinum-based chemotherapy using nationally representative real-world data from more than 280 US cancer clinics. Patients were followed-up from May 2011 to March 2020. Data analysis was performed between April and June 2021. Comparisons of interest were between atezolizumab vs docetaxel and atezolizumab vs nivolumab.ExposuresInitiation of atezolizumab, nivolumab, or docetaxel monotherapy.Main outcome and measuresThe main outcome was overall survival (OS).ResultsA total of 3336 patients (mean [SD] age, 67.1 [9.49] years; 1820 [54.6%] men and 1516 [45.4%] women) were assessed in the main analysis, including 206 patients receiving atezolizumab, 500 receiving docetaxel, and 2630 receiving nivolumab. Patients receiving atezolizumab were older than those treated with docetaxel (mean age [SD], 68.3 [9.4] years vs 65.6 [9.5] years), and were more likely to have been treated in an academic setting (39 patients [18.9%]) than those receiving docetaxel (49 patients [9.8%]) and nivolumab (128 patients [4.9%]). After adjustment for baseline characteristics, atezolizumab was associated with a significantly longer OS compared with docetaxel (adjusted hazard ratio [aHR], 0.79; 95% CI, 0.64-0.97). No significant difference in OS was observed between atezolizumab and nivolumab (aHR, 1.07; 95% CI, 0.89-1.28). These findings were consistent across all patient subgroups tested, and robust to plausible deviations from random missingness for Eastern Cooperative Oncology Group performance status in real-world data (eg, the tipping point for loss of a significantly beneficial effect for atezolizumab vs docetaxel was achieved if patients in the docetaxel group missing baseline Eastern Cooperative Oncology Group performance status had a mean performance status of 1.43 higher than expected).Conclusions and relevanceIn this comparative effectiveness study, atezolizumab was superior to docetaxel and matched nivolumab in prolonging OS in a real-world cohort of patients with advanced NSCLC who previously received platinum-based chemotherapy.
