Immune aberrations have been demonstrated in tumorogenesis, and myeloid-derived suppressor cells (MDSC) have shown to play a pivotal role in mediating immune suppression in animal models of human tumors. In the present study, we explored the clinical relevance of CD11b+/CD14−/CD15+/CD33+ MDSCs and the association of MDSCs with CD8+ cytotoxic T lymphocytes(More)
RATIONALE Myeloid-derived suppressor cells (MDSCs) are a heterogeneous family of myeloid cells that suppress T-cell immunity in tumor-bearing hosts. Their clinical relevance remains unclear. OBJECTIVES To identify subtypes of myeloid-derived suppressor cells in patients with non-small cell lung cancer (NSCLC) and their clinical relevance. METHODS(More)
Our study investigated whether tumor-associated macrophages (TAMs) in advanced non-small cell lung cancer (NSCLC) are related to treatment response to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) and may be a predictor of survival. Of 206 advanced NSCLC patients treated (first-line) with an EGFR-TKI at the study hospital from 2006(More)
Intravenous ports are widely used for oncology patients. However, catheter fractures may lead to the need for re-intervention. We aimed to identify the risk factors associated with catheter fractures. Between January 1 and December 31, 2006, we retrospectively reviewed the clinical data and plain chest films of 1,505 patients implanted with an intravenous(More)
PURPOSE Most of the patients with stage IIIA pN2 non-small cell lung cancer (NSCLC) develop recurrence after surgery. It is not clear whether post neoadjuvant chemotherapy tumor-associated macrophages is associated with recurrence. PATIENTS AND METHODS Stage IIIA pN2 NSCLC patients underwent cisplatin/docetaxel neoadjuvant chemotherapy and surgery were(More)
BACKGROUND/PURPOSE Isolated intrathoracic lymphadenopathy (IT-LAP) is clinically challenging because of the difficult anatomic location and wide range of associated diseases, including tuberculosis (TB). Although sampling via endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for histopathology is a major development, there is(More)
RATIONALE Fibrocytes possess increased differentiability into α-smooth muscle actin (α-SMA)(+) myofibroblasts in chronic obstructive asthma (COA) and contribute to pulmonary fibrosis. Endothelin-1 (ET-1) induces matrix-associated gene expression through the ETA receptor (ETAR) and promotes fibroblast differentiation. However, the mechanism of fibrocyte(More)
OBJECTIVES Docetaxel and pemetrexed have been validated as therapeutics for previously treated advanced non-small-cell lung cancer (NSCLC), but tolerability is a concern for standard treatment with docetaxel administered once every 3 weeks (tri-weekly 75-mg/m(2) schedule). We conducted this retrospective study to compare the efficacy and toxicity of weekly(More)
OBJECTIVE Smoking has been associated with tuberculosis (TB); however, the effects of smoking on the effectiveness of TB treatment remain unclear. MATERIALS AND METHODS Data were retrieved from case notes and interviews of subjects registered in the TB-reporting system from 2010 to 2012. Study cases were defined as subjects with TB-positive sputum(More)
INTRODUCTION The measurement of C-reactive protein (CRP) to confirm the stability of COPD has been reported. However, CRP is a systemic inflammatory biomarker that is related to many other diseases. OBJECTIVE The objective of this study is to discover a diagnostic biomarker for COPD. METHODS Sixty-one subjects with COPD and 15 healthy controls (10(More)
