Multicenter, Retrospective Study to Evaluate Necitumumab Plus Cisplatin and Gemcitabine After Immune Checkpoint Inhibitors in Advanced Squamous Cell Lung Cancer in Japan: The NINJA Study.

Introduction: Necitumumab plus gemcitabine and cisplatin (GCN) is a standard therapy for patients with advanced lung squamous cell carcinoma (LSqCC). However, the efficacy and tolerability of GCN in second-line or later treatment for patients previously treated with immune checkpoint inhibitors (ICIs) remain unknown.

Methods: This multicenter, retrospective, cohort study assessed the efficacy and tolerability of GCN initiated between November 1, 2019 and March 31, 2022 as second-line to fourth-line treatment in patients with advanced LSqCC who had been pretreated with ICIs.

Fatal rupture of pulmonary artery pseudoaneurysm after thoracic radiation therapy against lung squamous cell carcinoma: A case report and literature review.

Pulmonary artery pseudoaneurysm is a rare but fatal condition. It has been associated with lung cancer, abscesses, and radiation therapy. Identification in patients with hemoptysis is critical, and timely interventional therapy is warranted.

[Serious S-1-Induced Lung Injury Diagnosed by Early Lung Biopsy-A Case Report].

The patient was a 65-year-old man who developed dyspnea after 6 courses of S-1 and oxaliplatin(SOX)chemotherapy for advanced stomach cancer. The chemotherapy regimen consisted of SOX chemotherapy. The patient developed hypoxemia, and chest radiography revealed ground-glass opacity in both lungs.

Beneficial Effect of Early Intervention with Garenoxacin for Bacterial Infection-Induced Acute Exacerbation of Bronchial Asthma and Chronic Obstructive Pulmonary Disease.

Background: Chronic obstructive pulmonary disease (COPD) and asthma have similar clinical features and are both exacerbated by airway infection.

Objective: To determine whether garenoxacin mesylate hydrate (GRNX) added to the standard care for bacterial infection-induced acute exacerbation of asthma or COPD in adults has clinical benefits.

Method: This single-arm clinical trial was conducted from January 2015 to March 2016.

Distinct Afatinib Resistance Mechanisms Identified in Lung Adenocarcinoma Harboring an EGFR Mutation.

EGFR tyrosine kinase inhibitors (TKI) are associated with significant responses in non-small cell lung cancer (NSCLC) patients harboring -activating mutations. However, acquired resistance to reversible EGFR-TKIs remains a major obstacle. In particular, although the second-generation irreversible EGFR-TKI afatinib is currently used for treating NSCLC patients, the mechanisms underlying acquired afatinib resistance remain poorly understood.

Acquired Resistance Mechanisms to Combination Met-TKI/EGFR-TKI Exposure in Met-Amplified EGFR-TKI-Resistant Lung Adenocarcinoma Harboring an Activating EGFR Mutation.

Met-amplified EGFR-tyrosine kinase inhibitor (TKI)-resistant non-small cell lung cancer (NSCLC) harboring an activating EGFR mutation is responsive to concurrent EGFR-TKI and Met-TKI treatment in a preclinical model. Here, we determined that Met-amplified gefitinib-resistant cells acquire dual resistance to inhibition of EGFR and Met tyrosine kinase activities. PC-9 lung adenocarcinoma cells harboring 15-bp deletions (Del E746_A750) in EGFR exon 19 were treated with increasing concentrations of the Met-TKI PHA665752 and 1 μmol/L gefitinib for 1 year; three resistant clones were established via Met amplification.

[Successful Treatment of Seasonal Influenza A (H3N2) infection-related Hemophagocytic Lymphocytosis in an Elderly Man].

A 79-year-old man experienced severe chronic obstructive pulmonary disease (COPD) and was receiving treatment for ischemic heart disease. Starting from dizziness and chilliness, he lost consciousness after few days. He was taken to our emergency department.

Association of pharmacokinetics and pharmacogenomics with safety and efficacy of gefitinib in patients with EGFR mutation positive advanced non-small cell lung cancer.

Objectives: Gefitinib is a potent epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor and is a key drug for patients with EGFR mutation-positive advanced non-small cell lung cancer (NSCLC). The pharmacokinetics of orally administered gefitinib varies greatly among patients. We prospectively evaluated the association of pharmacokinetics and pharmacogenomics with the safety and efficacy of gefitinib in patients with EGFR mutation-positive advanced NSCLC.

Evaluation of the safety and efficacy of combination chemotherapy with vinorelbine and platinum agents for patients with non-small cell lung cancer with interstitial lung disease.

Background: Acute chemotherapy-associated exacerbation of interstitial lung disease (ILD) can occur in patients with non-small cell lung cancer (NSCLC). The safety and efficacy of cytotoxic chemotherapy has not yet been established for NSCLC with ILD. Thus, patients with advanced NSCLC with ILD usually receive only best supportive care.

Relationship of circulating tumor cells to the effectiveness of cytotoxic chemotherapy in patients with metastatic non-small-cell lung cancer.

The aim of this study was to investigate the relationship of the number of circulating tumor cells (CTCs) with the effectiveness of cytotoxic chemotherapy in patients with metastatic non-small-cell lung cancer (NSCLC). We prospectively evaluated CTCs in the peripheral blood of patients with previously untreated metastatic NSCLC. From May 2008 through August 2010, 33 patients (23 men and 10 women; median age, 64 years; range, 46-74 years) were enrolled.

Phase II trial of the combination of carboplatin and irinotecan in elderly patients with small-cell lung cancer.

Aim: The aim of the present phase II study was to assess the antitumour activity and safety of the combination of irinotecan and carboplatin in elderly patients with small-cell lung cancer (SCLC).

Material And Methods: Patients with previously untreated SCLC were eligible if they had a performance status of 0-2, were 70 years or older, and had adequate organ function. Patients were treated with carboplatin at an area under the plasma concentration versus time curve of 5 min/ml on day 1 and with irinotecan at 50mg/m(2) on days 1 and 8 every 3 weeks.

Phase II study of S-1, a novel oral fluoropyrimidine, and biweekly administration of docetaxel for previously treated advanced non-small-cell lung cancer.

Purpose: We examined the safety and efficacy of the combination of S-1 and biweekly docetaxel in patients with previously treated advanced non-small-cell lung cancer (NSCLC).

Methods: Patients with previously treated advanced NSCLC were eligible if they had a performance status of 2 or less, were 80 years or younger, and had adequate organ function. Forty-nine patients (38 men and 11 women; median age, 66 years; range 43-79 years) were enrolled.
