The same time, the mechanism underlying increased incidence of cancer in individuals with COPD is still not totally explained. It’s usually believed that an important role within this field could be played by chronic inflammation, throughout which several cytokines, chemokines, and development variables exert stimulatory action toward several elements of cancer cell progression.2 Probably the most basic components of cancer cell invasiveness, specifically in metastatic tumors, is their potential to migrate.5,6 In relation to COPD, the course in the pathology consists of increased secretion of a variety of agents, the activity of which could, at the very least theoretically, market the migration of lung cancer cells.7,8 In current years, significantly attention has been paid towards the function of chemokines as mediators of cancer cell migration, for example, chemokines CCL21, CXCL5, and CXCL12 have already been found to contribute towards the migratory properties of breast cancer cells.91 The identical chemokines are recognized to mediate various elements of lung cancer cell progression, including proliferation,12,13 adhesion,14 and invasion.15 At the similar time, their part within the migration of lung cancer cells, in particular in sufferers with COPD, remains unknown. This study was made to examine whether serum obtained from sufferers with COPD with several smoking status (smokers, former smokers, nonsmokers) andInternational Journal of COPD 2016:11 1061Correspondence: Barbara KunarKamiska Department of Pulmonology, allergology and respiratory Oncology, Pozna University of Healthcare sciences, szamarzewskiego 84 street, Pozna 60-569, Poland Tel/fax +48 6 1841 7061 e-mail [email protected] your manuscript | www.dovepress.comDovepresshttp://dx.doi.org/10.2147/COPD.S2016 Kunar-Kamiska et al.

(St Louis, MO, USA). Tissue culture plastics have been from Nunc (Roskilde, Denmark).Measurement of cancer cell migrationCancer cell migration by way of a polycarbonate membrane (eight pores) toward the chemotactic gradient generated by the serum from patients with COPD and from wholesome controls was examined using ChemoTx chambers (Neuro Probe, Gaithersburg, MD, USA).
