PURPOSE Although large-cell neuroendocrine carcinoma (LCNEC) of the lung shares many clinical characteristics with small-cell lung cancer (SCLC), little is known about its molecular features. We analyzed lung LCNECs to identify biologically relevant genomic alterations. EXPERIMENTAL DESIGN We performed targeted capture sequencing of all the coding exons(More)
Immunohistochemical analysis for the identification of clinically relevant biomarkers is important. However, there have been no detailed reports about the heterogeneous expressions of the various markers in squamous cell carcinoma of the lung. A total of 113 patients with squamous cell carcinoma of the lung with lymph node metastasis were included. The(More)
Denosumab reduces the incidence of skeletal-related events (SREs) in solid tumor patients with bone metastases (BM). However, there have been no detailed reports of the efficacy of denosumab in untreated non-squamous non-small cell lung cancer (NSCLC) patients with BM. The medical records of patients with untreated non-squamous NSCLC and BM at diagnosis at(More)
Cancer associated fibroblasts (CAFs) play important roles in the chemotherapeutic process, especially through influencing the resistance of tumor cells to molecular targeted therapy. Here we report the existence of a special subpopulation of patient-specific-CAFs that augment the sensitivity of EGFR gene mutation-positive lung cancer to the EGFR-tyrosine(More)
Although a few investigators have demonstrated the effect of concurrent chemoradiotherapy (CRT) for postoperative recurrent nonsmall cell lung cancer (NSCLC), the outcome of this treatment remains unclear. The aim of this study was to elucidate the efficacy and tolerability of concurrent CRT with cisplatin (CDDP) and vinorelbine (VNR) in patients with(More)
We describe the case of a 60-year-old man suffering from an advanced thymic neuroendocrine tumor with left supraclavicular lymph node and multiple bone metastases. The patient initially underwent systemic therapy with somatostatin analogues. Thereafter, peptide receptor radionuclide therapy (PRRT) was considered because the lesions had remained stable(More)
Histologic classification of invasive lung adenocarcinomas by predominant subtype has prognostic value. Papillary predominant adenocarcinoma (PPA) reportedly shows poorer prognosis than lepidic predominant adenocarcinoma (LPA); however, biological differences between PPA and LPA are unclear. The purpose of this study was to clarify biological differences(More)
