Clinical recommendations for perioperative immunotherapy-induced adverse events in patients with non-small cell lung cancer.

Perioperative adjuvant treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). In particular, the success of immune checkpoint inhibitors, such as antibodies against PD-1 and PD-L1, in patients with lung cancer has increased our expectations for the success of these therapeutics as neoadjuvant immunotherapy. Neoadjuvant therapy is widely used in patients with resectable stage IIIA NSCLC and can reduce primary tumor and lymph node stage, improve the complete resection rate, and eliminate microsatellite foci; however, complete pathological response is rare.

A continuous responder algorithm to optimize clinical management of small-cell lung cancer with progastrin-releasing peptide as a simple blood test.

This study aimed to investigate whether changes in progastrin-releasing peptide (ProGRP) levels correlate with treatment response and can be used to optimize clinical management of patients with small-cell lung cancer. Patients with small-cell lung cancer (any stage) receiving chemotherapy were eligible. ProGRP was measured in serum/plasma at baseline and after each chemotherapy cycle using the Elecsys ProGRP assay (Roche Diagnostics).

Icotinib as Adjuvant Treatment for Stage II-IIIA Lung Adenocarcinoma Patients with EGFR Mutation (ICWIP Study): Study Protocol for a Randomised Controlled Trial.

The efficacy and possible role of epidermal growth factor receptor tyrosine kinase inhibitors in treating early-stage non-small-cell lung cancer have yet to be established. Therefore, we aimed to explore the efficacy and safety of icotinib in completely resected EGFR-mutant stage II-IIIA lung adenocarcinoma patients who underwent standard chemotherapy. This is a randomised, double-blinded, placebo-controlled, multicentre, Phase III trial.

Macrophage Inhibitory Cytokine-1 as a Novel Diagnostic and Prognostic Biomarker in Stage I and II Nonsmall Cell Lung Cancer.

Background: Increased level of serum macrophage inhibitory cytokine-1 (MIC-1), a member of transforming growth factor-μ superfamily, was found in patients with epithelial tumors. This study aimed to evaluate whether serum level of MIC-1 can be a candidate diagnostic and prognostic indicator for early-stage nonsmall cell lung cancer (NSCLC).

Methods: A prospective study enrolled 152 patients with Stage I-II NSCLC, who were followed up after surgical resection.

Increased lung cancer mortality rates in the Chinese population from 1973-1975 to 2004-2005: An adverse health effect from exposure to smoking.

Background: Lung cancer incidence and mortality rates have increased substantially in China despite improvements in clinical diagnosis and treatment approaches as well as significant advances in the implementation of tobacco-control policies in recent decades.

Methods: Age-standardized mortality rates and age-specific rates of lung cancer in China were estimated for the periods 1973 to 1975, 1990 to 1992, and 2004 to 2005 using data from 3 National Death Surveys. Among patients with lung cancer who were identified from a hospital-based information system, the percentages of ever-smokers were analyzed according to histologic and demographic variables.

LFC131 peptide-conjugated polymeric nanoparticles for the effective delivery of docetaxel in CXCR4 overexpressed lung cancer cells.

CXCR4 is a chemokine receptor which is over expressed in multiple cancers including lung cancers. LFC131 peptide (d-Tyr-Arg-Arg-2-Nal-Gly), an inhibitor of CXCR4-ligand binding, is a low molecular weight CXCR4 antagonist. In this study, we developed novel LFC131 peptide surface conjugated O-carboxymethyl chitosan nanoparticles (O-CMC NP) to target CXCR4 over expressed A549 lung cancer cells.

Multicenter evaluation of a new progastrin-releasing peptide (ProGRP) immunoassay across Europe and China.

Background: We performed a multicenter evaluation of the Elecsys® progastrin-releasing peptide (ProGRP) immunoassay in Europe and China.

Methods: The assay was evaluated at three European and two Chinese sites by imprecision, stability, method comparison and differentiation potential in lung cancer.

Results: Intermediate imprecision across five analyte concentrations ranged from 2.

[A comparative study of complete video-assisted thoracoscopic lobectomy and video-assisted mini-thoracotomy in treatment of lung cancer].

Objective: To explore the clinical application value of complete video-assisted thoracoscopic (cVATS) lobectomy in the mini-invasive treatment of lung cancer.

Methods: 90 patients with non-small cell lung cancer (NSCLC) who had undergone lobectomy were reviewed. According to surgical approach, complete video-assisted thoracoscopic lobectomy group (cVATS, n = 47) and video-assisted mini-thoracotomy group (VAMT, n = 43) were studied.

Inhibition of SENP1 induces radiosensitization in lung cancer cells.

Lung cancer is one of the most common and lethal types of malignancy. To date, radiotherapy and chemotherapy have been used as the two major treatment methods. However, radioresistance of lung cancer remains a therapeutic hindrance.

Adenoviral delivery of the EMX2 gene suppresses growth in human gastric cancer.

Background: EMX2 is a human orthologue of the Drosophila empty spiracles homeobox gene that has been implicated in embryogenesis. Recent studies suggest possible involvement of EMX2 in human cancers; however, the role of EMX2 in carcinogenesis needs further exploration.

Results: In this study, we reported that down-regulation of EMX2 expression was significantly correlated with EMX2 promoter hypermethylation in gastric cancer.

Triparanol suppresses human tumor growth in vitro and in vivo.

Despite the improved contemporary multidisciplinary regimens treating cancer, majority of cancer patients still suffer from adverse effects and relapse, therefore posing a significant challenge to uncover more efficacious molecular therapeutics targeting signaling pathways central to tumorigenesis. Here, our study have demonstrated that Triparanol, a cholesterol synthesis inhibitor, can block proliferation and induce apoptosis in multiple human cancer cells including lung, breast, liver, pancreatic, prostate cancer and melanoma cells, and growth inhibition can be rescued by exogenous addition of cholesterol. Remarkably, we have proved Triparanol can significantly repress Hedgehog pathway signaling in these human cancer cells.

A case of huge esophageal carcinosarcoma.

Carcinosarcoma of the esophagus is a rare malignant neoplasm with both epithelial and mesenchymal (sarcomatous) components. We describe a case of a 72-year-old man with a huge esophageal tumor which could often have been considered inoperable. However, the patient underwent a curative resection and had a good prognosis.

The bone morphogenetic protein antagonist Gremlin is overexpressed in human malignant mesothelioma.

Gremlin is a member of the bone morphogenetic protein (BMP) antagonist family and its antagonistic effect is likely through direct binding to BMP proteins. As an antagonist of BMP, Gremlin plays a role in regulating organogenesis, body patterning and tissue differentiation. Recent studies have shown a deregulation of Gremlin in several types of human cancers.
