Lung adenocarcinoma has increased incidence over the past years and is the cause for almost 50% of deaths attributable to lung cancer. The objective of this paper is to identify activated pathways associated with lung adenocarcinoma based on gene co-expression network analysis.

Kyoto Encyclopedia of Genes and Genomes pathway analysis of dysregulated genes was performed based on Expression Analysis Systematic Explorer test to illuminate the biological pathways. Co-expression networks of lung adenocarcinoma in different tumor Stages (IA, IB, IIA, IIB, IIIA, IIIB, and IV) were constructed by Empirical Bayes approach to reweight gene pair scores. Pathway activity analysis was conducted to compute the distribution of pathways in different stages and to identify "activated" pathways in lung adenocarcinoma.

We evaluated 211 dysregulated genes between lung adenocarcinoma patients and normal controls. Pathway activity analysis was performed and P values of pathways, which obtained from co-expression networks (Stage IA, IB, IIA, IIB, IIIA, IIIB, and IV), were calculated. Cell cycle, progesterone-mediated oocyte maturation, and oocyte meiosis were activated during all stages in lung adenocarcinoma.

We successfully identified three activated pathways (cell cycle, progesterone-mediated oocyte maturation, and oocyte meiosis) in different Stages (IA, IB, IIA, IIB, IIIA, IIIB, and IV) of lung adenocarcinoma.

Spirometry is an important tool to monitor treatment response in diseases such as chronic obstructive pulmonary disease and asthma. However, there is lack of evidence to support its application to evaluate response to chemotherapy in advanced lung cancer. It might be a useful adjunct to the imaging-based response evaluation which lacks functional assessment of lungs.

The study was conducted to evaluate the change in spirometry in lung cancer patients after chemotherapy and to find its correlation with change in physical tumor size.

Sixty-two advanced lung cancer patients who were eligible for palliative chemotherapy were enrolled. Baseline tumor size evaluation using Response Evaluation Criteria in Solid Tumor (RECIST)-based scoring system, and spirometry was done. Four cycles of double agent (platinum doublets) chemotherapy were administered, after which treatment response was evaluated. Repeat spirometry was analyzed and correlated with changes in physical tumor size.

Twenty-five patients showed a response (all partial response) to four cycles of chemotherapy. Small cell carcinoma showed a better response rate than non-small cell carcinoma (78% vs. 39%). There was statistically significant improvement in forced expiratory volume in 1 (FEV

) (P = 0.01) and forced vital capacity (P = 0.03) in responders as compared to nonresponders. Change in FEV1 showed a statistically significant correlation with the change in tumor size (RECIST score) (r = -0.34; P = 0.04).

Improvement in spirometry correlates with the tumor response as judged using RECIST criteria after chemotherapy. Further studies with bigger sample size are required to consolidate the results.

There are "blind spots" on chest computed tomography (CT) where pulmonary nodules can easily be overlooked. The number of missed pulmonary nodules can be minimized by instituting a training program with particular focus on the depiction of nodules at blind spots.

The purpose of this study was to assess the variation in lung nodule detection in chest CT based on location, attenuation characteristics, and reader experience.

We selected 18 noncalcified lung nodules (6-8 mm) suspicious of primary and metastatic lung cancer with solid (n = 7), pure ground-glass (6), and part-solid ground-glass (5) attenuation from 12 chest CT scans. These nodules were randomly inserted in chest CT of 34 patients in lung hila, 1

costochondral junction, branching vessels, paramediastinal lungs, lung apices, juxta-diaphragm, and middle and outer thirds of the lungs. Two residents and two chest imaging clinical fellows evaluated the CT images twice, over a 4-month interval. Before the second reading session, the readers were trained and made aware of the potential blind spots. Chi-square test was used to assess statistical significance.

Pretraining session Fellows detected significantly more part-solid ground-glass nodules compared to residents (P = 0.008). A substantial number of nodules adjacent to branching vessels and posterior mediastinum were missed. Posttraining session There was a significant increase in detectability independent of attenuation and location of nodules for all readers (P < 0.0008).

Dedicated chest CT training improves detection of lung nodules, especially the part-solid ground-glass nodules. Detection of nodules adjacent to branching vessels and the posterior mediastinal lungs is difficult even for fellowship-trained radiologists.

Lung cancer is the most common malignant disease and is the topmost cause of cancer deaths in the world across all age groups and in both sexes. It is the most common cause of cancer deaths in developed countries and is also rising at an alarming rate in the developing countries.

The present study was undertaken to explore the clinicopathological and molecular profile of bronchogenic carcinoma in northwestern population of India.

A total of 136 consecutive patients with histologically proven bronchogenic carcinoma, registered between May 2014 and April 2016 at a tertiary care hospital in New Delhi, India, were analyzed.

Out of a total of 136 diagnosed cases, 6% were in the third to fourth decade of life, 49% in the fifth to sixth decade, and 45% in the seventh decade and above. https://www.selleckchem.com/products/epacadostat-incb024360.html Seventy-one percent of patients were male. Smoking was the major risk factor in 65.40% of patients. About 33% of female patients were smokers with a significant overlap in the use of smoking objects. Twenty-one percent of patients had been initially empirically treated with antitubercular therapy.
