Osteopontin (OPN) is known to be overexpressed in numerous carcinomas. Although abundant OPN has been reported to be correlated with poor survival in non-small cell lung cancer (NSCLC) but their clinical and prognostic significance in SCLC remains unknown. In this study, RNA-sequencing was used to obtain gene expression data in SCLC tissue samples and OPN expression levels were then investigated using qPCR, immunohistochemical and Western blot. We found OPN was one of the most upregulated genes. Besides, the correlation of OPN with tumor clinicopathological characteristics was evaluated and we found OPN was associated with advanced tumor stages...

BACKGROUND: Neuroendocrine breast cancer is a rare entity that was defined in 2003 by the World Health Organization as a separate breast cancer subtype. The diagnosis of neuroendocrine breast cancer requires the presence of neuroendocrine features in at least 50% of malignant cells, the exclusion of non-mammary primary tumors, as well as the presence of an in situ component in breast histology. The treatment and prognosis of neuroendocrine breast cancer are still not well established...

Introduction The impact of the introduction of video assisted thoracoscopic surgery (VATS) on the management of lung cancer 20 years ago has been well documented. However, the uptake of VATS lobectomy in surgical practice worldwide has been slower than expected. We believe that this is partly due to a lack of consensus on how this procedure should be integrated into training programmes. We present our initial experience with a newly developed training model, which could help bridge the divide between open and VATS lobectomy...

Chemotherapy-induced peripheral neuropathy (CIPN), a consequence of peripheral nerve fiber dysfunction or degeneration, continues to be a dose-limiting and debilitating side effect during and/or after cancer chemotherapy. Paclitaxel, a taxane commonly used to treat breast, lung, and ovarian cancers, causes CIPN in 59-78% of cancer patients. Novel interventions are needed due to the current lack of effective CIPN treatments. Our studies were designed to investigate if nicotine can prevent and/or reverse paclitaxel-induced peripheral neuropathy in a mouse model of CIPN, while ensuring that nicotine will not stimulate lung tumor cell proliferation or interfere with the anti-tumor properties of paclitaxel...

Lung adenocarcinoma is one of the types of non‑small cell lung carcinoma, which tends to be treated with surgical therapy rather than radiation therapy. It occurs in smokers and non‑smokers, and is the most common form of lung cancer among non‑smokers and women. Gene rearrangements, including ALK, ROS1 and RET, and gene mutations, including epidermal growth factor receptor (EGFR), HER2, Kristen rat sarcoma viral oncogene homolog, BRAF, phosphoinositide‑3‑kinase, catalytic, α polypeptide and MET, have been identified in lung adenocarcinoma, which enable targeted therapy in lung adenocarcinoma, for example erlotinib, gefitinib and afatinib, which are EGFR inhibitors...

La-related protein 1 (LARP1) is a conserved RNA-binding protein and is known to regulate 5'-terminal oligopyrimidine tract (TOP) mRNA translation. Dysregulated LARP1 has been reported to be related to the development of several cancers. However, the exact function and mechanism of LARP1 in non-small cell lung cancer (NSCLC) is largely unknown. In the present study, we found that the mRNA levels of LARP1 were increased in NSCLC cells compared to those in normal control cells. Knockdown of LARP1 inhibited cell proliferation, migration and invasion in NSCLC cells and tumourigenicity in H520 cells...

Discovery of the epidermal growth factor receptor gene mutation and the anaplastic lymphoma kinase chromosomal translocation in non-small cell lung cancer has prompted efforts around the world to identify many less common targetable oncogenic drivers. Such concerted efforts have been variably successful in both non-squamous and squamous cell carcinomas of the lung. Some of the targeted therapies for these oncogenic drivers have received regulatory approval for clinical use, while others have modest clinical benefit...

Programmed death ligand 1 (PD-L1) as one the most important immune checkpoint was verified to involve in chemotherapy resistance in non-small cell lung cancer (NSCLC). Ginsenoside Rg3 is isolated from Chinese herb-Panax ginseng which is recognized to boost immune and has anti-cancer activity against a majority of carcinomas including NSCLC. In this study, we aim to identify whether Rg3 could attenuate the PD-L1 expression induced by resistance to cisplatin and draw out the underlying mechanisms of PD-L1 in this process...

It has been shown that various tRNA synthetases exhibit non-canonical activities unrelated to their original role in translation. We have previously described a signal transduction pathway in which serine 207 phosphorylated lysyl-tRNA synthetase (P-s207 LysRS) is released from the cytoplasmic multi-tRNA synthetase complex (MSC) into the nucleus, where it activates the transcription factor MITF in stimulated cultured mast cells and cardiomyocytes. Here we describe a similar transformation of LysRS due to EGFR signaling activation in human lung cancer...

Elevated VEGF mRNA (-ΔCT) was significantly associated with adenocarcinoma histology (vs squamous) and advanced NSCLC clinical stages in a univariable analysis; however, this association did not remain significant in the multivariable analysis. Of interest, a Kaplan-Meier analysis showed that NSCLC patients with higher VEGF mRNA (-ΔCT ≥10) had a significantly poorer overall survival and shorter postoperative relapse time in adenocarcinoma and in stage III/IV than those with VEGF mRNA of -ΔCT <10 (P < 0...

BACKGROUND: With advent of personalized medicine, precise classification of malignant tumors becomes essential. Squamous cell carcinoma (SCC) is rarely found in serous effusions and has morphologic and immunohistochemical (IHC) overlap with other neoplasms. METHODS: 17-year review identified 49 fluids from 26 patients where SCC was recognized. RESULTS: SCC was more frequent in pleural fluid (84%) and rare in other effusions. Lung SCC was common (65%), followed by head and neck (16%), with other origins less represented...

BACKGROUND: One immunotherapeutic agent for patients with advanced non-small cell lung carcinoma, pembrolizumab, has a companion immunohistochemistry (IHC)-based assay that predicts response by quantifying programmed death-ligand 1 (PD-L1) expression. The current study assessed the feasibility of quantifying PD-L1 expression using cytologic non-small cell lung carcinoma specimens and compared the results with those from small biopsy and surgical resection specimens. METHODS: PD-L1 expression was quantified using the IHC-based 22C3 pharmDx assay, with "positivity" defined as staining in ≥50% viable tumor cells; ≥ 100 tumor cells were required for test adequacy...

The prognostic role of tumor-infiltrating tryptase(+) mast cells in human solid tumors remains controversial. Herein, we conducted a meta-analysis including 28 published studies with 4224 patients identified from PubMed and EBSCO to assess the prognostic impact of tumor-infiltrating tryptase(+) mast cells in human solid tumors. We found that tryptase(+) mast cell infiltration significantly decreased overall survival (OS) and disease-free survival (DFS) in all types of solid tumors. In stratified analyses, tryptase(+) mast cell infiltration was significantly associated with worse OS in non-small cell lung cancer, hepatocellular carcinoma and 5-year survival in colorectal cancer...
