ABSTRACT

Purpose: Few data have been published on the management of patients with synchronous head-and-neck cancer (HNC) and lung cancer (LC). This observational study was undertaken to describe the management of these patients in multiple centers. Materials and Methods: All patients consecutively diagnosed with synchronous HNC and LC in 26 French centers were included. Information was collected on patients' clinical characteristics, management, and outcomes. Those characteristics and treatments were analyzed descriptively. Kaplan-Meier progression-free and overall survival probabilities were estimated. Results: The study included 132 patients: 83% male; median age: 63.7 (range: 62.1-65.4) years; all current or former smokers; Eastern Cooperative Oncology Group performance status: 0 or 1 for 21.9% or 65.9% of the patients, respectively; cardiovascular comorbidities: 63%; chronic obstructive pulmonary disease: 33%; and previous cancer: 11%. HNC histology was 98% squamous: 23.5% oral cavity, 26.5% oropharyngeal, 22.0% hypopharyngeal, and 28.0% laryngeal. LCs were mainly localized (47.7% Stage I and 9.9% Stage II): 38% squamous, 49% adenocarcinomas, and 13% others. LC diagnosis impacted HNC management for 38% of the patients, with a median time from HNC diagnosis to first HNC treatment of 40 days. HNC impacted LC management for 48% of the patients, with a median time from LC diagnosis-to-LC treatment interval of 41 days. Conclusions: Synchronous LC at HNC diagnosis impacted management and outcomes of both cancers. Specific recommendations should be elaborated to improve the management of these patients.

ABSTRACT

BACKGROUND: The role and timing of whole or stereotaxic brain radiotherapy (BR) in patients with advanced non-small cell lung cancer (aNSCLC) and asymptomatic brain metastases (aBMs) are not well established. This study investigates whether deferring BR until cerebral progression was superior to upfront BR for patients with aNSCLC and aBM. METHODS: This open-label, multicenter, phase III trial, randomized (1:1) aNSCLC patients with aBMs to receive upfront BR and chemotherapy: platin-pemetrexed and bevacizumab in eligible patients, followed by maintenance pemetrexed with or without bevacizumab, BR arm, or the same chemotherapy with BR only at cerebral progression, chemotherapy (ChT) arm. Primary endpoint was progression-free survival (PFS), secondary endpoints were overall survival (OS), global, extra-cerebral and cerebral objective response rate (ORR), toxicity, and quality of life [ClinicalTrials.gov identifier: NCT02162537]. RESULTS: The trial was stopped early because of slow recruitment. Among 95 included patients, 91 were randomized in 24 centers: 45 to BR and 46 to ChT arms (age: 60 ± 8.1, men: 79%, PS 0/1: 51.7%/48.3%; adenocarcinomas: 92.2%, extra-cerebral metastases: 57.8%, without differences between arms.) Significantly more patients in the BR-arm received BR compare with those in the ChT arm (87% versus 20%; p < 0.001); there were no significant differences between BR and ChT arms for median PFS: 4.7, 95% confidence interval (CI):3.4-7.5 versus 4.8, 95% CI: 2.4-6.5 months, for median OS: 8.5, 95% CI:.6-11.1 versus 8.3, 95% CI:4.5-11.5 months, cerebral and extra-cerebral ORR (27% versus 13%, p = 0.064, and 30% versus 41%, p = 0.245, respectively). The ChT arm had more grade 3/4 neutropenia than the BR arm (13% versus 6%, p = 0.045); others toxicities were comparable. CONCLUSION: The significant BR rate difference between the two arms suggests that upfront BR is not mandatory in aNSCLC with aBM but this trial failed to show that deferring BR for aBM is superior in terms of PFS from upfront BR.

ABSTRACT

OBJECTIVE: To describe the spectrum and outcome of central nervous system complications associated with immune checkpoint inhibitors (CNS-ICI). METHODS: Patients with CNS-ICI were identified and their characteristics compared with ICI-related peripheral neuropathy (PN-ICI). RESULTS: We identified 19 patients with CNS-ICI. The patients were receiving nivolumab (n=8), pembrolizumab (n=6), a combination of ipilimumab-nivolumab (n=3), ipilimumab-durvalumab (n=1), or atezolizumab (n=1). Underlying malignancies included non-small-cell lung cancer (n=8), melanoma (n=3), and other less common tumours (n=8). Neurological phenotypes were limbic encephalitis (n=8), meningoencephalitis (n=4) and cerebellitis (n=4). Two patients developed isolated confusion and one parkinsonism. Associated autoantibodies included onconeural (Ma2, n=7; Hu, n=1), astrocytic (glial fibrillar acidic protein, n=2) and neuronal surface (contactin-associated protein-like 2, n=1) specificities. ICIs were withheld and corticosteroid treatment was given in all cases. Five patients received intravenous immunoglobulin, two rituximab, one plasmapheresis and one infliximab. Overall, six patients died. Readministration of ICI was attempted in three patients, without further relapses. Non-small-cell lung cancer was significantly more frequent in patients with CNS-ICI (p<0.01), while melanoma and ipilimumab treatment were more common in PN-ICI (p<0.01 and p=0.01). Conversely, CNS-ICI cases were more frequently antibody-positive than PN-ICI (p<0.01) and showed a strong trend towards poorer outcome (p=0.053). CONCLUSION: Three main clinical phenotypes characterise CNS complications of ICIs, each with distinct immunological background, disease course and response to treatment. Other clinical manifestations (including parkinsonism and steroid-responsive confusion) are also possible. Underlying cancers, antibody prevalence and outcome appear different from those of patients with PN-ICI.

ABSTRACT

INTRODUCTION: Using immune-checkpoint inhibitors (ICIs) to manage cancer is associated with various immune-related adverse events. Central and/or peripheral neurological disorders are rare and potentially serious. We analyzed the characteristics of non-small-cell lung cancer (NSCLC) patients who developed immune-related encephalitis under anti-programmed-death protein-1 or its ligand (PD-1/PD-L1). METHODS: Clinical, biological and radiological characteristics of ICI-treated NSCLC patients with immune-related encephalitis, from 6 centers, were evaluated retrospectively. RESULTS: The 6 centers included 9 patients: all men, all smokers, median (range) age 67 (48-77) years, 78% adenocarcinomas, first- or second-line ICI for 5 and 4 patients, respectively. Two patients had non-active cerebral metastases at ICI onset. A median of 5 (1-22) ICI infusions preceded neurological symptoms, the most frequent being confusion (78%), fever (45%) and cerebellar ataxia (33%). CSF analyses revealed a median white blood cell count of 22/mm3 (1-210/mm3), with hyperlymphocytosis in 8 patients and high protein levels in all. All bacteriological and virological analyses were negative. Cerebral MRI was considered normal for 5 patients; 4 patients had FLAIR hypersignals consistent with brain parenchyma inflammation. Three patients required intensive care. All patients received corticosteroids (different doses), a median of 8.5 (6-18) days post-onset. Corticosteroids achieved rapid symptom regression without sequelae in 8 patients. The last patient, with the longest time until corticosteroid introduction, died. ICIs were never restarted in any patient. CONCLUSION: Immune encephalitis, a rare but serious complication of anti-PD-1/PD-L1 therapy, carries a good prognosis when managed with early corticosteroids.

ABSTRACT

BACKGROUND: The resistance mutation T790M is reported in 50-60% of patients pretreated with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). Osimertinib has been approved in these patients, but data in octogenarians remain rare. OBJECTIVE: The objective of this retrospective analysis was to evaluate in real life the efficacy of osimertinib in a population of octogenarian patients. METHODS: This retrospective multicentric study included pretreated octogenarian patients with EGFR T790M-mutated advanced non-small cell lung cancer (NSCLC) in the setting of the French early access program for osimertinib. The primary endpoints were progression-free survival (PFS) and overall survival (OS) from osimertinib initiation. RESULTS: In total, 43 patients were included (mean age 84.6 years; women 90.7%: adenocarcinoma 100%; never smokers 90.5%; at osimertinib initiation: performance status ≥ 2, 42.4%; stage 4, 93.0%; brain metastases 16.3%). Patients received a median of two lines of treatment before osimertinib initiation, and all received first- or second-generation EGFR TKIs before osimertinib (first line in 79.1%). Osimertinib was used as a second-line treatment in 41.9% of cases and third line or more in 58.1%. Median PFS was 17.5 (95% confidence interval [CI] 12.2-19.0) months for the entire population: 20.6 (95% CI 18.8-not reached) months in patients with brain metastases and 16.7 (95% CI 10.4-18.9) months in patients without (p = 0.1). There was no significant difference for osimertinib treatment as second or third line or more (17.1 vs. 18.6 months, respectively). OS was 22.8 (95% CI 15.7-not reached) months from osimertinib initiation. CONCLUSION: The efficacy of osimertinib as second-line treatment or more in octogenarian pretreated patients with EGFR T790M-mutated advanced NSCLC in a real-life setting was similar to that in randomized controlled trials.

ABSTRACT

BACKGROUND: Chromosomal translocations involving the anaplastic lymphoma kinase gene (ALK) are rare oncogenic events found in 3-5% of non-small-cell lung cancers (NSCLC). Limited data have been published on the management of these patients outside clinical trials. OBJECTIVE: To investigate the clinical characteristics and management of patients with NSCLC harboring ALK translocations (ALK+) in a real-life setting in France. METHODS: This multicenter, observational, retrospective study included all NSCLC patients harboring ALK translocations diagnosed in participating centers between January 2012 and December 2014. Patient data include clinical characteristics, disease management, and outcomes [progression-free survival (PFS) and overall survival (OS)]. RESULTS: The 31 participating centers reported data on 132 patients, of whom 51% (n = 67) were male. The median age was 60.1 ± 14.5 (standard deviation) years; 89% (n = 106/119) had performance status 0/1 at diagnosis; 79% (n = 103/130) were non- or former smokers; 93% (n = 120/129) had adenocarcinomas and 74%(n = 97)/19%(n = 25)/7%(n = 10) had disease stages IV/III/I-II at diagnosis, respectively; co-mutations included EGFR (n = 2), BRAF (n  = 2), KRAS (n = 1), and HER2 (n = 1). Of the patients with stage IV NSCLC (n = 97), 96% received first-line treatment [75% chemotherapy-based, 21% ALK tyrosine kinase inhibitor (TKI)], with an associated response rate (RR), disease-control rate (DCR), and PFS of 42%, 64%, and 7.5 [95% confidence interval (CI) 5.9-9.5] months, respectively; 62% received second-line treatment (28% chemotherapy, 72% ALK TKI) with an associated RR, DCR, and PFS of 43.4%, 70%, and 4.7 (95% CI 4.0-8.1) months, respectively. The 2-year OS was 56.7% (95% CI 45.5-70.4%); median OS was not reached. CONCLUSION: The results of this real-life analysis suggest that the prognosis of NSCLC patients with theALK translocation may be better than that of the overall NSCLC population, but the outcomes were poorer than those of ALK+ NSCLC patients included in clinical studies.
