Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the adult mammalian brain, but exerts physiologic effects other than that on neurotransmitter in non-neuronal peripheral tissues and organs. GABA may affect cancer growth through activation GABA receptors. We investigated the gene expression of GABA receptors in tissue of non-small(More)
The expression of programmed cell death 1 (PD-1) and its ligand (PD-L1) has been observed in various epithelial-originated malignancies. However, whether the expression of PD-L1 on tumor cells or the expression of PD-1 on tumor-infiltrating lymphocytes (TILs) is associated with patients' survival remains controversial.Electronic databases were searched for(More)
BACKGROUND With the development of imaging technology, an increasing number of multiple primary lung cancers (MPLC) are diagnosed in recent years. However, there is still ambiguity in the stage classification rules for patients with MPLC. Our purpose was to access the prognosis of synchronous and metachronous MPLC. METHODS A systematic literature search(More)
BACKGROUND Visceral pleural invasion (VPI) is considered an aggressive and invasive factor in non-small cell lung cancer (NSCLC). Recent studies found that depending on tumor size, VPI influences T stage, but there is no consensus on whether VPI is important in node-negative NSCLC. In addition, its role in stage IB NSCLC is still uncertain. In this(More)
Adjuvant chemotherapy is recommended for postoperative stage II-IIIB nonsmall cell lung cancer patients. However, its effect remains controversial in stage IB patients. We, therefore, performed a meta-analysis to compare the efficacy of adjuvant chemotherapy versus surgery alone in stage IB patients. Six electronic databases were searched for relevant(More)
BACKGROUND Currently, blockade of the programmed cell death 1 (PD-1)/PD-1 ligand 1 (PD-L1) signaling pathway has been proved one of the most promising immunotherapeutic strategies against cancer. Several antibodies have been developed to either block the PD-1 or its ligand PD-L1 are under development. So far, a series of phase I trials on PD-1/PD-L1(More)
OBJECTIVES To comparatively assess the impact of non-intubated intravenous anaesthesia with spontaneous ventilation (NIIASV) versus intubated anaesthesia with single-lung mechanical ventilation (IASLV) on early outcomes of video-assisted thoracoscopic (VATS) anatomical resection of non-small-cell lung cancer (NSCLC). METHODS A total of 339 patients with(More)
PURPOSE According to the lung cancer staging project, T1a (≤ 2 cm) non-small-cell lung cancer (NSCLC) should be additionally classified into ≤ 1 cm and > 1 to 2 cm groups. This study aimed to investigate the surgical procedure for NSCLC ≤ 1 cm and > 1 to 2 cm. METHODS We identified 15,760 patients with T1aN0M0 NSCLC after surgery from the Surveillance,(More)
An increased risk of non-small cell lung cancer (NSCLC) in cystic fibrosis (CF) patients and carriers of CF transmembrane conductance regulator (CFTR) mutations has been proposed. However, the role of CFTR in lung cancer remains controversial. In the present study, CFTR expression was assessed in 165 NSCLC tumors and 22 normal lung samples with validation(More)
