Chemoimmunotherapy is the standard first-line therapy for patients with extensive-stage small cell lung cancer (ES-SCLC). However, whether findings from pivotal trials can be extrapolated to clinical practice setting remains unclear.To compare treatment outcome gaps following chemoimmunotherapy ES-SCLC between those who met and did not meet eligibility criteria used in previous trials.A prospective cohort study was conducted September 1, 2019, 30, 2020, at 32 hospitals Japan, least 12 months...

Pleomorphic carcinoma (PC) of the lung is a rare type non‐small cell cancer, exhibiting aggressive behavior and resistance to chemotherapy radiotherapy. A previous study reported that PCs expressed high levels PD‐L1, suggesting potential efficacy immune checkpoint inhibitors in these tumors. We retrospectively reviewed clinical records three patients with PC treated nivolumab: 59‐year‐old woman (Case 1), 66‐year‐old man 2), an 83‐year‐old 3). PD‐L1 was highly their tumor cells. Two cases...

Abstract Background Despite the wide-spread use of immune checkpoint inhibitors (ICIs) in cancer chemotherapy, reports on patients developing acquired resistance (AR) to ICI therapy are scarce. Therefore, we first investigated characteristics associated with shorter durable responses treatment and revealed clinical patterns AR prognosis involved. Methods We conducted a retrospective multi-center cohort study that included NSCLC PD-L1 tumor proportion scores ≥50% who received first-line...

The aim of the present study was to analyze impact metastatic status on prognosis epithelial growth factor receptor (EGFR) mutation-positive patients with non-small cell lung cancer (NSCLC) treated first-generation EGFR-tyrosine kinase inhibitors (TKIs). A total 178 EGFR stage IIIB-IV and relapsed NSCLC who were gefitinib or erlotinib as first-line treatment enrolled in study. Metastatic status, progression-free survival (PFS), overall (OS) treatment-response rates investigated. association...

Abstract To investigate the exposure–safety relationships of afatinib in Japanese population, we performed population pharmacokinetics (PK) analysis advanced non-small cell lung cancer patients harboring epidermal growth factor receptor mutation. Plasma samples were collected at 0.5–1, 2–3, 8–12, and 24 h after oral (40 mg) administration on day 1 8. concentrations determined using high-performance liquid chromatography. Data was analyzed following approach software Phoenix ® NLME TM Version...

Background Pembrolizumab is currently approved as a first-line therapy for advanced non-small cell lung cancer (NSCLC) patients with programed death ligand-1 (PD-L1) expression ≥50%. However, the association between efficacy of pembrolizumab and PD-L1 levels in ≥50% has not been fully elucidated. Methods We retrospectively analyzed NSCLC tumor proportion score (TPS) who received at 11 institutions Japan February 2017 January 2018. Patients were divided into TPS 50–89% 90–100% (ultra-high...

Background Pirfenidone is an antifibrotic agent that potentially effective for the treatment of idiopathic pulmonary fibrosis (IPF). However, no study has reported on its prophylactic value against chemotherapy‐associated acute IPF exacerbations when combined with chemotherapy non‐small cell lung cancer (NSCLC). The present assessed safety and effectiveness pirfenidone carboplatin‐based or immune checkpoint inhibitors (ICIs) in patients NSCLC. Methods A total 14 NSCLC who received from 2013...

Nivolumab is an anti-PD-1 blocking monoclonal antibody approved for the treatment of non-small cell lung cancer (NSCLC). However, some patients on immunotherapy may experience rapid progression and worsening clinical status, known as hyperprogressive disease. We retrospectively reviewed records with NSCLC administered nivolumab therapy at Toneyama National Hospital, Japan, from January 2016 to 2018. Of 87 therapy, five experienced during one cycle therapy. Four were treated corticosteroids...

Abstract Background Pembrolizumab is effective as first-line therapy against advanced non-small cell lung cancer (NSCLC) in patients with programmed death ligand-1 (PD-L1) expression levels ≥50% [1]. However, it not all patients, and the factors predicting responses among this population remain unknown. Methods We retrospectively analyzed NSCLC a PD-L1 tumor proportion score (TPS) > 50%, who received monotherapy pembrolizumab from February 1, 2017 to April 30, 2018. The study included 11...

Malignant pleural effusion (MPE) is associated with poor treatment outcome in patients NSCLC receiving immune checkpoint inhibitors (ICIs). ICIs and chemotherapy (ICI/Chemo) combination therapy currently the standard for NSCLC, some ICI/Chemo regimens nonsquamous (non-Sq) contain bevacizumab (BEV), which effective controlling MPE may enhance response. This study aimed to determine optimal first-line this clinical population.We retrospectively enrolled consecutive non-Sq who received or...

Although small cell lung cancer (SCLC) is initially sensitive to chemotherapy, it recurs in most cases. Standard regimens for salvage chemotherapy have not been established, and the prognosis of relapsed SCLC remains poor. In present study, we investigated clinical efficacy safety nanoparticle albumin-bound paclitaxel (nab-paclitaxel) treatment SCLC. this retrospective multicenter analysis, 14 patients (3 women 11 men; median age 71 years) with received nab-paclitaxel alone or combination...

The diagnostic yield of peripheral pulmonary lesions (PPLs) by flexible bronchoscopy (FB) is still insufficient. To improve the bronchoscopy, several techniques such as endobronchial ultrasound (EBUS), virtual bronchoscopic navigation (VBN), and rapid on-site evaluation (ROSE) have been examined. primary purpose present study was to evaluate usefulness combining EBUS, VBN, ROSE for diagnosing small PPLs.Patients with PPLs 30 mm or less on chest computed tomography (CT) were prospectively...

Abstract Background The therapeutic efficacy of cytotoxic anticancer drugs has been reported to be enhanced after immune checkpoint inhibitors (ICI) in non–small cell lung cancer; however, it is unclear whether the same applicable for small cancer (SCLC). We evaluated second‐line amrubicin (AMR) following first‐line platinum‐based chemotherapy and ICI combination therapy (chemo‐ICI) SCLC. Patients Methods retrospectively enrolled consecutive patients with SCLC treated AMR as a chemo‐ICI...
