Background: Real-world data have suggested a detrimental effect of steroid use in patients with advanced non-small-cell lung cancer (NSCLC) receiving immunotherapy. However, previous studies included heterogeneous cohorts of patients receiving different lines of treatment with several immuno-oncology agents and various combinations of chemotherapy and immuno-oncology agents., Patients and Methods: A comprehensive clinicopathologic database of patients with NSCLC and programmed cell death ligand 1 >50% treated with frontline pembrolizumab monotherapy was constructed in 14 centers in Italy, Spain, Greece, and Switzerland. A multivariate analysis adjusting for the established prognostic factors was performed using a Cox regression model., Results: For the 265 eligible patients, the median age at diagnosis was 67 years, 66% were male, 90% were current or former smokers, 18% had had an Eastern Cooperative Oncology Group performance status of 2 or 3. Of the NSCLC subtypes, 64% were adenocarcinoma and 25% were squamous cell. Of the patients, 18% had had brain metastases at diagnosis and 24% had received steroids before or during pembrolizumab treatment. The median time to progression was 4.4 months with and 13.7 months without steroid use (hazard ratio [HR], 2.55; 95% confidence interval [CI], 1.69-3.85; log-rank P < .001). The median survival was 22.5 months for the whole cohort, 7.7 months for the steroid group, and not reached for the non-steroid group (HR, 3.64; 95% CI, 2.34-5.68; log-rank P < .001). On multivariate analysis accounting for all established prognostic variables, steroid use was still independently associated with a high risk of progression (HR, 1.864; 95% CI, 1.179-2.949; P = .008) and death (HR, 2.292; 95% CI, 1.441-3.644; P < .001) CONCLUSIONS: In patients with advanced NSCLC and programmed cell death ligand 1 expression > 50% receiving frontline pembrolizumab monotherapy, any use of steroids before or during treatment was associated with an 86% increase in the risk of progression and a 2.3-fold increase in the risk of death, even accounting for palliative indication-related bias, including the presence of central nervous system metastasis. The use of steroids for palliative indications should be restricted to absolutely necessary for patients receiving immuno-oncology monotherapy., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: The role of immune-related adverse events (irAEs), as a surrogate predictor of the efficacy of checkpoint inhibitors, has not yet been described in the setting of first-line, single-agent pembrolizumab for patients with metastatic non-small-cell lung-cancer (NSCLC) with a programmed death-ligand 1 (PD-L1) expression of ≥ 50%., Patients and Methods: We previously conducted a multicenter retrospective analysis in patients with treatment-naive metastatic NSCLC and a PD-L1 expression of ≥ 50% receiving first-line pembrolizumab. Here, we report the results of the irAE analysis and the potential correlation between irAEs and clinical outcomes., Results: A total of 1010 patients were included in this analysis; after a 6-week landmark selection, 877 (86.8%) patients were included in the efficacy analysis. Any grade irAEs (P < .0001), grade 3/4 irAEs (P = .0025), leading to discontinuation irAEs (P = .0144), multiple-site and single-site irAEs (P < .0001), cutaneous irAEs (P = .0001), endocrine irAEs (P = .0227), pulmonary irAEs (P = .0479), and rheumatologic irAEs (P = .0018) were significantly related to a higher objective response rate. Any grade irAEs (P < .0001), single-site irAEs (P < .0001), multiple-site irAEs (P = .0005), cutaneous irAEs (P = .0042), endocrine irAEs (P < .0001), gastrointestinal irAEs (P = .0391), and rheumatologic irAEs (P = .0086) were significantly related to progression-free survival. Any grade irAEs (P < .0001), single-site irAEs (P < .0001), multiple-site irAEs (P = .0003), cutaneous irAEs (P = .0002), endocrine irAEs (P = .0001), and rheumatologic irAEs (P = .0214) were significantly related to overall survival., Conclusions: This study confirms the feasibility and the safety of first-line, single-agent pembrolizumab, in a large, real-world cohort of patients with NSCLC with PD-L1 expression ≥ 50%. The occurrence of irAEs may be a surrogate of clinical activity and improved outcomes in this setting., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Other than the programmed cell death ligand 1 (PD-L1) value, oncologists have only the clinical characteristics of patients with advanced non-small-cell lung cancer (aNSCLC) to determine candidates for immunotherapy. A clinical prognostic score composed of the Eastern Cooperative Oncology Group performance status, sex, histologic type, stage, platinum-based first-line therapy, and response to first-line therapy has categorized 3 prognostic groups for patients undergoing second-line chemotherapy. We sought to validate the same score for patients with aNSCLC treated with second- or further-line immunotherapy., Materials and Methods: We collected data from 2 Italian centers. A score was generated to divide patients into 3 prognostic groups: best, score < 5; intermediate, score 5 to 9; and worst, score > 9. Overall survival (OS) and progression-free survival (PFS) were the endpoints., Results: A total of 347 patients were included for analysis. Their median age was 66 years (range, 30-88 years), most were aged < 70 years (67.5%), 70.7% were men, 79.5% were smokers, and 74.6% had had adenocarcinoma. The Eastern Cooperative Oncology Group performance status was 0 for 23%, 1 for 54.5%, and 2 for 22.5%. Of the 347 patients, 28% were in the best prognosis, 51% in the intermediate, and 21% in the worst prognosis group, respectively. The median OS was 18.0 months for the best, 8.5 months for the intermediate (hazard ratio [HR] vs. best, 1.83; 95% confidence interval [CI], 1.35-2.47; P < .001) and 2.6 months for worst (HR vs. best, 5.77; 95% CI, 3.99-8.33; P < .001) group. The median PFS was 3.4 months for the best, 3.7 months for the intermediate (HR vs. best, 1.35; 95% CI, 1.03-1.77; P = .032), and 1.9 months for the worst (HR vs. best, 2.51; 95% CI, 1.80-3.50; P < .001) group., Conclusions: The prognostic score was able to predict the outcomes of patients with aNSCLC who had received immunotherapy. The worst category showed a dismal life expectancy and probably would not benefit from active systemic therapy. Thus, for these patients, best supportive care could be the best choice., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Second-line immunotherapy (IO) has shown an overall survival benefit. However, only 18% to 20% of patients with advanced non-small-cell lung cancer (aNSCLC) will respond, with a median progression-free survival (PFS) of 2 to 4 months. Thus, biomarkers to select those patients most likely to benefit from IO are greatly needed., Patients and Methods: We conducted a retrospective analysis of 154 patients with aNSCLC who had received anti-programmed cell death 1 therapy as second line or further treatment. We assessed the absolute neutrophil, lymphocyte, monocyte, and eosinophil counts at baseline (T0) and the second (T1) and third (T2) cycles. The neutrophil/lymphocyte ratio (NLR), derived-NLR (dNLR), lymphocyte/monocyte ratio (LMR), and their percentage of change at T1 and T2 compared with T0 were evaluated. The clinical characteristics and lactate dehydrogenase (LDH) level were also considered. Univariate and multivariate analyses were performed. Significant biomarkers for PFS on multivariate analysis were combined in a prognostic score., Results: For overall survival, the negative prognostic biomarkers were Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2, NLR at T0, and dNLR at T1; the LMR at T0, T1, and T2 was identified as a positive prognostic biomarker. For PFS, the negative prognostic biomarkers were ECOG PS 2, liver metastases, NLR at T0, dNLR at T1 and T2, and ≥ 30% increase of NLR from T0 to T1; the positive prognostic biomarkers were heavy smoking, LDH, and LMR at T2. The ≥ 30% increase of LMR from T0 to T1 and T0 to T2 correlated with the overall response rate. A prognostic score (EPSILoN score; smoking, ECOG PS, liver metastases, LDH, NLR) identified 3 prognostic groups (median PFS, 10.2, 4.9, and 1.7 months, respectively; P < .001)., Conclusions: The EPSILoN score combines 5 baseline clinical and blood biomarkers and can help to identify patients with aNSCLC who will most likely benefit from second-line IO. Further studies are warranted., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Patients with 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 subgroups is still unclear. In this study, we investigated the incidence and the clinical correlates of VTE in patients with ROS1-rearranged NSCLC enrolled in the METROS trial (NCT02499614)., Patients and Methods: The METROS trial is a prospective phase II study designed to assess efficacy, safety, and tolerability of crizotinib in patients with pre-treated metastatic NSCLC ROS1 rearrangement (cohort A) or with MET amplification or MET exon 14 mutation (cohort B). Patients with ROS1-rearranged NSCLC enrolled within cohort A and the expansion cohort of the trial were included in the primary analysis., Results: Among 48 patients with ROS1-rearranged NSCLC enrolled in the METROS study, 20 (41.6%) of 48 had at least 1 VTE event. Among them, 7 (35%) of 20 patients had ≥ 2 VTE events. VTE events consisted of pulmonary embolism (46.4%), deep vein thrombosis (39.2%), renal vein thrombosis (7.1%), internal jugular thrombosis (3.5%), and peripheral inserted central catheter-related thrombosis (3.5%). VTE events occurred at disease progression in 35.7% of cases, at diagnosis in 32.1% of cases, and during chemotherapy or crizotinib in 17.8% and 14.2%, respectively., Conclusion: The incidence of VTE is 3- to 5-fold higher in patients harboring ROS1-rearrangment than previously observed for the general population with NSCLC. Larger studies are warranted to confirm our findings and determine whether the molecular profile of NSCLC should be incorporated into a risk-stratification tool and decision-making algorithm for VTE diagnosis and prophylaxis., (Copyright © 2019 Elsevier Inc.

Background: Owing to the expected poor long-term outcomes and high postoperative morbidity and mortality, patients with stage IIIA-N2 tumors candidate to pneumonectomy (PN) are usually excluded from surgery. This study aims to analyze the outcome of patients who underwent PN to prove its safety and feasibility., Patients and Methods: We retrospectively analyzed data from 233 patients who underwent PN for N2 non-small-cell lung cancer (NSCLC) between 1998 and 2015. Eighty-five patients were occult N2 disease (group 1), whereas 148 patients underwent induction therapy (IT) for stage IIIA-N2 (group 2)., Results: Overall morbidity, postoperative mortality, and 90-day mortality rates were 46.8%, 2.6%, and 8.6%, respectively. The 2 groups (group 1 vs. 2) had similar postoperative and 90-day mortality rates: 2.4% versus 2.7% (P = 1.00), and 9.4% versus 8.1% (P = .81), respectively. The incidence of major morbidity was higher and statistically significant in group 2 compared with group 1: 23% versus 12.9% (P = .1). Postoperative bronchopleural fistula occurred in 4.7% (4/85) of patients with occult N2 (group 1) and in 10.1% (15/148) of patients undergoing IT (group 2) (P = .10). Median overall survival (OS) was 2.2 years, with a 3 and 5-year OS of 43.4% and 31.6%, respectively. Disease-free survival (DFS) was 1.5 years, with 3 and 5-year DFS of 41.6% and 32%, respectively; no difference in OS and DFS between the 2 groups was found., Conclusions: Considering the acceptable morbidity and mortality rate and the long-term survival, PN should not be excluded for selected patients with stage IIIA-N2 NSCLC as a matter of principle., (Copyright © 2018 Elsevier Inc.

Introduction: Contract research organization (CRO) support is largely included in clinical trial management, although its effect in terms of time savings and benefit has not yet been quantified. We performed a retrospective multicenter analysis of lung cancer trials to explore differences in term of trial activation timelines and accrual for studies with and without CRO involvement., Materials and Methods: Results regarding study timelines from feasibility data to first patient enrollment were collected from 7 Italian thoracic oncology departments. The final accruals (screened/enrolled patients) are reported. We considered CRO/sponsor-administered and CRO-free trials according to who was responsible for the management of the crucial setup phases., Results: Of 113 trials, 62 (54.9%) were CRO-administered, 34 (30.1%) were sponsor-administered, and 17 (15.0%) were CRO-free. The median time from feasibility invitation to documentation obtainment was 151 days in the CRO-administered trials versus 128 in the sponsor-administered and 120 in the CRO-free trials. The time from document submission to contract signature was 142 days in the CRO-administered versus 128 in the sponsor-administered and 132 in the CRO-free trials. The time from global accrual opening to first patient enrollment was 247 days for the CRO-administered versus 194 in the sponsor-administered and 151 in the CRO-free trials. No significant differences were observed in terms of the median overall timeline: 21 months in the CRO-administered, 15 in the sponsor-administered, and 18 months in the CRO-free studies (P = .29)., Conclusion: Although no statistically significant differences were identified, the results of our analysis support the idea that bureaucratic procedures might require more time in CRO-administered trials than in sponsor-administered and CRO-free studies. This bureaucratic delay could negatively affect Italian patients' screening and enrollment compared with other countries., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Beyond progression after tyrosine kinase inhibitor in EGFR-positive non-small-cell lung cancer patients (BE-POSITIVE) was the first Italian multicenter observational study that reported the outcomes of first-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) in a "real-life" Caucasian EGFR-mutated non-small-cell lung cancer (NSCLC) population. The sharing of multi-institutional experiences represents a crucial strategy to enrich knowledge about uncommon EGFR mutations. Therefore, we performed a post hoc analysis of the BE-POSITIVE study., Patients and Methods: Data of advanced NSCLC patients with uncommon EGFR mutations who received first-line first-generation EGFR-TKIs in 24 Italian Hospitals were collected. In this analysis we aimed to evaluate overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) of EGFR-TKIs in NSCLC patients harboring uncommon EGFR mutations., Results: Thirty-five patients harboring uncommon EGFR mutations (any mutation other than deletion 19 or substitution of leucine by arginine at codon 858) were included of the original 312 EGFR-mutated cases. Most of them were female (n = 20, 57.1%), former smokers (n = 23, 65.7%), with adenocarcinoma (n = 31, 88.6%). The most frequent EGFR mutations were G719X (n = 6, 17.2%) and L861Q (n = 5, 14.2%). The population presented an ORR of 25.7%, a median PFS of 5.19 months, and a median OS of 14.49 months. When stratified according to type of EGFR mutation, median OS ranged from 3.65 months for unspecified mutations to 21.29 for double EGFR mutations. Median PFS ranged from 1.77 months for unspecified mutations to 20.83 months for concomitant EGFR-anaplastic lymphoma kinase alteration. ORR varied from 0% in exon 18, 20 and double gene alteration to 66.6% in exon 19., Conclusion: Our study supports the existence of a strong outcome heterogeneity within patients harboring uncommon EGFR mutations, which needs to be clarified to achieve a real personalized treatment strategy., (Copyright © 2017 Elsevier Inc.

Introduction: Pemetrexed maintenance therapy (MT) after induction with platinum-based chemotherapy has recently become a common treatment strategy for advanced nonsquamous non-small-cell lung cancer (NSCLC). However, the benefits of MT should be weighed with consideration of the patients' perceptions and preferences. The aim of the present study was to evaluate patients' attitudes toward MT and to describe physicians' awareness of their patients' inclinations., Materials and Methods: We administered a 12-question anonymous survey and the Distress Thermometer Questionnaire to patients with advanced or recurrent nonsquamous NSCLC. The survey was also distributed to the referring physicians., Results: From December 2014 to July 2015, 92 patients and 37 physicians were enrolled. All 92 patients completed the questionnaire at T0 (before starting chemotherapy) and 56.5% also did so at T1 (after completion of induction). The physicians completed the survey only at T0. Most patients had a positive attitude toward MT at both T0 (78.9%) and T1 (86.5%), and 100% of the physicians thought their patients would be in favor of MT. The physicians believed that their patients' attitudes toward MT would decrease proportionally with the reduction in the magnitude of the overall survival increase and expected benefits. The decrease expected by the physicians was much greater than that reported by the patients. This was especially true for an overall survival increase as small as 1 month (51.9% of patients accepting MT vs. 13.5% supposed by physicians) or when the only treatment benefit was radiologic tumor stabilization (69.3% of patients accepting MT vs. 37.8% supposed by physicians)., Conclusion: NSCLC patients have a generally positive attitude toward MT, which is not directly proportional to the expected benefits and greater than the attitude expected by physicians., (Copyright © 2016 Elsevier Inc.

Randomized clinical trials (RCTs) of concurrent epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) plus chemotherapy for unselected patients with advanced non-small-cell lung cancer (NSCLC) produced negative results. Intercalated administration could avoid the reduction of chemotherapy activity due to G 1 cell-cycle arrest from EGFR-TKIs. A PubMed search was performed in December 2015 and updated in February 2016. The references from the selected studies were also checked to identify additional eligible trials. Furthermore, the proceedings of the main international meetings were searched from 2010 onward. We included RCTs comparing chemotherapy intercalated with an EGFR-TKI versus chemotherapy alone for patients with advanced NSCLC. Ten RCTs were eligible (6 with erlotinib, 4 with gefitinib): 39% of patients had a known EGFR mutational status, 43% of whom EGFR mutation positive. The intercalated combination was associated with a significant improvement in overall survival (OS; hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.71-0.95; P = .01), progression-free survival (PFS; HR, 0.60; 95% CI, 0.53-0.68; P < .00001), and objective response rate (ORR; odds ratio [OR], 2.70; 95% CI, 2.08-3.49; P < .00001). Considering only first-line trials, similar differences were found in OS (HR, 0.85; 95% CI, 0.72-1.00; P = .05), PFS (HR, 0.63; 95% CI, 0.55-0.73; P < .00001), and ORR (OR, 2.21; 95% CI, 1.65-2.95; P < .00001). In EGFR mutation-positive patients, the addition of an intercalated EGFR-TKI produced a significant benefit in PFS (129 patients; HR, 0.24; 95% CI, 0.16-0.37; P < .00001) and ORR (168 patients; OR, 11.59; 95% CI, 5.54-24.25; P < .00001). In patients with advanced NSCLC, chemotherapy plus intercalated EGFR-TKIs was superior to chemotherapy alone, although a definitive interpretation was jeopardized by the variable proportion of patients with EGFR mutation-positive tumors included., (Copyright © 2016 Elsevier Inc.

Introduction: Cisplatin with pemetrexed (CP) and carboplatin with paclitaxel and bevacizumab (CbTB) are standard first-line treatments for patients with advanced nonsquamous (NS) non-small-cell lung cancer (NSCLC). Quality of life (QoL) is a key objective in the management of advanced NSCLC. Thus, effect on QoL could be an additional factor in the choice of treatment., Patients and Methods: Patients with untreated stage IIIB/IV NS-NSCLC and Eastern Cooperative Oncology Group performance status of 0 or 1 were randomized to receive first-line chemotherapy with cisplatin 75 mg/m(2) and pemetrexed 500 mg/m(2), every 3 weeks, for 6 cycles followed by maintenance pemetrexed; or carboplatin area under the curve 6, paclitaxel 200 mg/m(2), and bevacizumab 15 mg/kg, every 3 weeks, for 6 cycles followed by maintenance bevacizumab. The primary end point was the difference in QoL between the 2 treatment arms after 12 weeks of maintenance, measured using the EuroQoL 5 Dimensions-Index (EQ5D-I) and EQ5D-visual analogue scale (EQ5D-VAS)., Results: One hundred eighteen patients were randomized to CP (n = 60) or CbTB (n = 58). Baseline characteristics were well balanced. The proportion of patients evaluable for the primary end point was lower than planned. After 12 weeks of maintenance, the difference between mean changes in EQ5D-I was 0.137, favoring CP (95% confidence interval [CI], -0.02 to 0.29, Wilcoxon P = .078), although not statistically significant; and the difference between mean changes in EQ5D-VAS was 0.97 (95% CI, -9.37 to 11.31, Wilcoxon P = .41)., Conclusion: Although the study was underpowered because of a small number of patients evaluable for the primary end point, QoL did not differ between treatment arms. Other factors such as comorbidities and schedule should be used when deciding on first-line treatment., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background: The purpose of this study was to evaluate the efficacy of afatinib in EGFR-mutant metastatic NSCLC patients with acquired resistance to erlotinib or gefitinib., Materials and Methods: We retrospectively analyzed the outcome of patients with EGFR-mutant advanced NSCLC treated with afatinib after failure of chemotherapy and EGFR TKIs., Results: A total of 96 individuals were included in the study. According to EGFR status, most patients (n = 63; 65.6%) harbored a deletion in exon 19, and de novo T790M mutation was detected in 2 cases (T790M and exon 19). Twenty-four (25%) patients underwent repeated biopsy immediately before starting afatinib and secondary T790M was detected in 8 (33%) samples. Among the 86 patients evaluable for efficacy, response rate was 11.6%, with a median progression free-survival (PFS) and overall survival (OS) of 3.9 and 7.3 months, respectively. No significant difference in PFS and OS was observed according to type of last therapy received before afatinib, type of EGFR mutation or adherence to Jackman criteria, and patients benefiting from afatinib therapy had longer PFS and OS (P < .001). Outcome results for repeated biopsy patients were similar to the whole population, with no evidence of response in T790M-positive patients. All patients were evaluable for toxicity, and 81% experienced an AE of any grade, with grade 3 to 4 AEs, mainly diarrhea and skin toxicity, occurring in 19 (20%) patients., Conclusion: Our results showed that afatinib has only modest efficacy in a real life population of EGFR mutant NSCLC patients with acquired resistance to erlotinib or gefitinib., (Copyright © 2014 Elsevier Inc.

Introduction/background: Patients with advanced NSCLC who experience disease progression after second-line therapy might receive further active treatment. LIFE was an Italian cohort multicenter observational study composed of a cross-sectional and a longitudinal phase., Patients and Methods: In the longitudinal phase, described here, the primary aim was to determine the proportion of patients receiving third-line therapy among those who received second-line active treatment according to clinical practice. The proportion of patients receiving further treatment lines was also estimated., Results: The longitudinal phase was conducted between January and August 2012. Of 464 patients who began second-line therapy outside of clinical trials within the baseline evaluation, 56 (12.1%) were still receiving second-line therapy at the end of the observation period and 17 (3.7%) withdrew during or after second-line therapy. Of the remaining 391 patients, 158 (40.4%) received third-line treatment outside of clinical trials: 93 received a third-line chemotherapy and 65 a targeted agent. The main reason for interrupting third-line treatment was disease progression or death. During the same observation period, 25 of 113 patients who completed a third-line therapy received a fourth line of treatment. From diagnosis of NSCLC to the end of observation, biomarkers were tested in 323 patients (59.7%): epidermal growth factor receptor mutations in 315 (58.2%), Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) mutations in 83 (15.3%) and Anaplastic lymphoma kinase (ALK) translocation in 84 (15.5%)., Conclusion: In Italian clinical practice, the proportion of patients with advanced NSCLC receiving more than 2 treatment lines of therapy is not negligible., (Copyright © 2014 Elsevier Inc.
