Transforming growth factor (TGF)-β regulates a wide variety of cellular responses, including cell growth arrest, apoptosis, cell differentiation, motility, invasion, extracellular matrix production, tissue fibrosis, angiogenesis, and immune function. Although tumor-suppressive roles of TGF-β have been extensively studied and well-characterized in many cancers, especially at early stages, accumulating evidence has revealed the critical roles of TGF-β as a pro-tumorigenic factor in various types of cancer. This review will focus on recent findings regarding epithelial-mesenchymal transition (EMT) induced by TGF-β, in relation to crosstalk with some other signaling pathways, and the roles of TGF-β in lung and pancreatic cancers, in which TGF-β has been shown to be involved in cancer progression. Recent findings also strongly suggested that targeting TGF-β signaling using specific inhibitors may be useful for the treatment of some cancers. TGF-β plays a pivotal role in the differentiation and function of regulatory T cells (Tregs). TGF-β is produced as latent high molecular weight complexes, and the latent TGF-β complex expressed on the surface of Tregs contains glycoprotein A repetitions predominant (GARP, also known as leucine-rich repeat containing 32 or LRRC32). Inhibition of the TGF-β activities through regulation of the latent TGF-β complex activation will be discussed.

Lung cancer contributes substantially to the global burden of disease and healthcare costs. New screening modalities using low-dose computerized tomography are promising tools for early detection leading to curative surgery. However, the screening and follow-up diagnostic procedures of these techniques may be costly. Focusing on prevention is an important factor to reduce the burden of screening, treatment, and lung cancer deaths. The International Agency for Research on Cancer has identified several lung carcinogens, which we believe can be considered actionable when developing prevention strategies. To curb the societal burden of lung cancer, healthcare resources need to be focused on early detection and screening and on mitigating exposure(s) of a person to known lung carcinogens, such as active tobacco smoking, household air pollution (HAP), and outdoor air pollution. Evidence has also suggested that these known lung carcinogens may be associated with genetic predispositions, supporting the hypothesis that lung cancers attributed to differing exposures may have developed from unique underlying genetic mechanisms attributed to the exposure of interest. For instance, smoking-attributed lung cancer involves novel genetic markers of risk compared with HAP-attributed lung cancer. Therefore, genetic risk markers may be used in risk stratification to identify subpopulations that are at a higher risk for developing lung cancer attributed to a given exposure. Such targeted prevention strategies suggest that precision prevention strategies may be possible in the future; however, much work is needed to determine whether these strategies will be viable.

Pathogenesis sequences in Gejiu miners with lung cancer: an introduction

Tin miners in Gejiu, Yunnan Province, China are at high risk of developing lung cancer with significant occupational characteristics. Tissue samples from these miners presented pathological characteristics, such as fibroplasia in carcinomas, peri-cancerous tissue in lung cancers, and hyperplasia and dysplasia of epithelial cells in peri-cancerous tissue. Carcinomas induced by Yunnan tin mine dust in the animal experiment underwent inflammation, fibroplasia, hyperplasia, dysplasia, and carcinogenesis of epithelial cells. A correlated and synergistic relationship was observed between bronchial epithelial cell transformation and fibroblast activation in vitro induced by mine dust. Fibroblast hyperplasia and activation are important factors that promote the transformation and carcinogenesis of epithelial cells. Our findings suggested that pulmonary fibrosis may increase the risk and promote the occurrence of lung cancer, which can lead to lung fiber hyperplasia.

Xuanwei City (formerly known as Xuanwei County) locates in the northeastern of Yunnan Province and is rich in coal, iron, copper and other mines, especially the smoky (bituminous) coal. Unfortunately, the lung cancer morbidity and mortality rates in this region are among China’s highest, with a clear upward trend from the mid-1970s to mid-2000s. In 2004–2005, the crude death rate of lung cancer was 91.3 per 100 000 in the whole Xuanwei City, while that for Laibin Town in this city was 241.14 per 100 000. The epidemiologic distribution (clustering patterns by population, time, and space) of lung cancer in Xuanwei has some special features, e.g., high incidence in rural areas, high incidence in females, and an early age peak in lung cancer deaths. The main factor that associates with a high rate of lung cancer incidence was found to be indoor air pollution caused by the indoor burning of smoky coal. To a certain extent, genetic defects are also associated with the high incidence of lung cancer in Xuanwei. Taken together, lung cancer in this smoky coal combustion region is a unique model for environmental factor-related human cancer, and the current studies indicate that abandoning the use of smoky coal is the key to diminish lung cancer morbidity and mortality.

MicroRNAs and lung cancers: from pathogenesis to clinical implications

Lung cancer is the leading cause of cancer-related deaths in the US and worldwide. Better understanding of the disease is warranted for improvement in clinical management. Here we summarize the functions of small-RNA-based, posttranscriptional gene regulators, i.e. microRNAs, in the pathogenesis of lung cancers. We discuss the microRNAs that play oncogenic as well as tumor suppressive roles. We also touch on the value of microRNAs as markers for diagnosis, prognosis and the promising field of microRNA-based novel therapies for lung cancers.

Diffuse cystic lung diseases are uncommon but can present a diagnostic challenge because increasing number of diseases have been associated with this presentation. Cyst in the lung is defined as a round parenchymal lucency with a well-defined thin wall (<2 mm thickness). Focal or multifocal cystic lesions include blebs, bullae, pneumatoceles, congenital cystic lesions, traumatic lesions, and several infectious processes such as coccidioidomycosis, Pneumocystis jiroveci pneumonia, and hydatid disease. “Diffuse” distribution in the lung implies involvement of all lobes. Diffuse lung involvement with cystic lesions can be seen in pulmonary lymphangioleiomyomatosis, pulmonary Langerhans’ cell histiocytosis, lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, amyloidosis, light chain deposition disease, honeycomb lung associated with advanced fibrosis, and several other rare causes including metastatic disease. High-resolution computed tomography of the chest helps define morphologic features of the lung lesions as well as their distribution and associated features such as intrathoracic lymphadenopathy. Correlating the tempo of the disease process and clinical context with chest imaging findings serve as important clues to defining the underlying nature of the cystic lung disease and guide diagnostic evaluation as well as management.

Video-assisted thoracoscopic surgery (VATS) provides a new approach for treating early-stage lung cancer. Lobectomy by VATS has many advantages over conventional thoracotomy, such as shorter recovery time, less postoperative pain, and faster resumption of a normal lifestyle. However, there is still much debate on the role of VATS in lobectomy for the treatment of lung cancer. Concerns regarding safety, the extent of mediastinal lymph node dissection, and long-term survival have made some surgeons apprehensive of its validity for lung cancer. In this paper, we review the development of thoracoscopy, the present status of VATS for early stage of non-small cell lung cancer (NSCLC), and comparison between VATS and open thoracotomy in the management of NSCLC.
