e20601 Background: Central nervous system (CNS) metastases (mets) occur in 30% of patients with advanced non-small cell lung cancer (NSCLC) and are associated with poor overall survival (OS). Although nivolumab, a programmed death-1 immune checkpoint inhibitor antibody, has demonstrated a longer survival benefit compared with docetaxel in previously treated NSCLC patients (CheckMate 017 and 057; N Engl J Med, 2015), patients with symptomatic or untreated CNS mets were excluded in these trials. In CheckMate 012 Arm M, 2 of 12 patients (16.7%) with untreated CNS mets showed intracranial responses, but the effect of nivolumab treatment for CNS mets was not fully investigated. Methods: To investigate the effect and safety of nivolumab for CNS mets in NSCLC patients, we retrospectively analyzed 48 patients with NSCLC who were treated with nivolumab from February 2016 to December 2016 at Okayama University Hospital. Results: Twenty-nine patients (60%) had no CNS lesions (group A) and 19 patients (40%) had brain mets (BM) (group B). In group B, 15 patients (79%) received radiotherapy (RT) for BM, including 5 patients who received RT just before nivolumab treatment. The responses of extra-CNS lesions to nivolumab are shown in the table. The PFS was longer in group A than in group B (p=0.14). In group B, the PFS of patients who received prior RT tended to be longer than in those without RT (p=0.42); OS was not reached in either group. In group B, the effects of nivolumab treatment for CNS mets were evaluated in 12 patients: SD occurred in 3 patients (25%), PD in 4 patients (33%), and NE in 5 patients (42%). All 4 patients with PD in the CNS lesion also showed PD in the extra-CNS lesion. In group A, no patients showed progression only in the CNS lesion. Conclusions: In this retrospective study, there were no patients treated only with nivolumab who showed a response to CNS mets. RT prior to nivolumab might be more effective, so future investigations should involve additional cases and prospective studies. [Table: see text]

Abstract Background The purpose of this study was to compare the efficacy of osimertinib (OSI) versus afatinib (AFA) in patients with T790M-positive, non-small-cell lung cancer (NSCLC) and multiple central nervous system (CNS) metastases after failure of initial epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment. Methods Consecutive patients with T790M-positive NSCLC and multiple CNS metastases after failure of initial EGFR-TKI treatment were retrospectively identified from our medical institution during 2016–2018 and underwent either oral 80 daily OSI or oral 40 daily AFA every 3 weeks for up to 6 cycles, until disease progression, intolerable adverse events (AEs), or death. The co-primary endpoints were overall survival (OS) and progression-free survival (PFS). Results The cohort consisted of 124 patients (OSI: n = 60, mean age = 64.24 years [SD: 12.33]; AFA: n = 64, mean age = 64.13 years [SD: 13.72]). After a median follow-up of 24 months (range, 3 to 28), a significant improvement in OS was detected (hazard ratio [HR] 0.59, 95% confidence interval [CI], 0.39–0.91; p = 0.0160; median, 13.7 months [95% CI, 11.1–14.8] for OSI vs 9.6 months [95% CI, 8.4–10.2] for AFA). The median duration of PFS was significantly longer with OSI than with AFA (HR 0.62; 95% CI, 0.41–0.91; p = 0.014; median, 4.5 months [95% CI, 3.5–5.7] vs 3.9 months [95% CI, 3.1–4.8]). The proportion of grade 3 or higher adverse events (AEs) was lower with OSI (22.4%) than with AFA (39.4%). Conclusions In patients with T790M-positive NSCLC and multiple CNS metastases after failure of initial EGFR-TKI treatment, OSI may be associated with significantly improved survival benefit compared with AFA, with a controllable tolerability profile.

Abstract Background Non–small-cell lung cancer (NSCLC) has been reported to develop in patients with interstitial pneumonia (IP); however, clinical, radiological, and pathological features remain to be elucidated. Methods We retrieved the records of 120 consecutive NSCLC patients associated with IP who underwent surgery at Toranomon Hospital between June 2011 and May 2017. We classified the patients into three groups according to NSCLC location using high-resolution computed tomography: group A, within a fibrotic shadow and/or at the interface of a fibrotic shadow and normal lung; group B, within emphysematous tissue and/or at the interface of emphysematous tissue and normal lung; and group C, within normal lung. In 64 patients, programmed death ligand-1 (PD-L1) status was assessed with immunohistostaining. Results Most of the patients (89; 70%) were classified as group A. This group tended to have squamous cell carcinoma with the usual interstitial pneumonia (UIP). These cancers were located mainly in the lower lobes and seven of the eight postoperative acute exacerbations (pAE) of IP developed in this group. NSCLC in the group B were mainly squamous cell carcinomas located in the upper lobes. No patient with PD-L1 negative was classified into group B. None of the patients in group C showed UIP. and most of the cancers were adenocarcinoma. The frequency of epidermal growth factor receptor mutation-positive NSCLC was the highest in this group. Conclusions The three groups each showed characteristic features in terms of tumor location, histopathology, PD-L1 expression, and frequency of pAEof IP.
