The purpose of this study was to assess the risk of lung cancer occurrence among Egyptian workers involved in the rubber industry using two circulating protein biomarkers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This study was performed in a rubber manufacturing factory in Shubra El-Kheima region in Greater Cairo, Egypt. Environmental assessment for the suspended particulate matter of size 10 \u00b5m (PM10) concentrations was done. Levels of plasma pro-surfactant protein B (pro-SFTPB) and serum high-sensitivity C-reactive protein (HsCRP) were measured among the studied population ( n = 155) who were divided into two groups. The first group included 75 workers exposed to rubber manufacturing process while the control group involved 80 administrative subjects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The levels of PM10 neither exceeded the Egyptian nor the international permissible limits where the highest levels were observed in the mixing department. However, through medical history and clinical examination, it was observed that some general and respiratory manifestations were more prevalent among the exposed group when compared with their controls. Laboratory investigations revealed that the mean values of pro-SFTPB and HsCRP levels among exposed workers were significantly higher than those of the control group. These increased circulating proteins levels were strongly and positively correlated with each other and with the duration of employment of exposed workers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The study results support the conclusion that prolonged occupational exposure to rubber manufacturing process is associated with an elevated risk of lung cancer.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0748233720923504","type":"journal-article","created":{"date-parts":[[2020,5,18]],"date-time":"2020-05-18T08:04:33Z","timestamp":1589789073000},"page":"237-249","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Prediction of lung cancer risk using circulating pro-surfactant protein B and high-sensitivity C-reactive protein among Egyptian workers in the rubber industry"],"prefix":"10.1177","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3698-9343","authenticated-orcid":false,"given":"Basma Hussein","family":"Mourad","sequence":"first","affiliation":[{"name":"Department of Occupational and Environmental Medicine, Faculty of Medicine, Cairo University, Cairo, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,5,18]]},"reference":[{"key":"bibr1-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.2011.501"},{"key":"bibr2-0748233720923504","doi-asserted-by":"publisher","DOI":"10.11606\/issn.1679-9836.v98i1p60-72"},{"key":"bibr3-0748233720923504","first-page":"104","volume":"16","author":"Arslan S","year":"2010","journal-title":"Journal of Agricultural Sciences"},{"key":"bibr4-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1177\/216507991306100505"},{"key":"bibr5-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2012.5521"},{"key":"bibr6-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyx146"},{"key":"bibr7-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2009.27.0454"},{"key":"bibr8-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1539\/joh.49.418"},{"key":"bibr9-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201508-1545CI"},{"key":"bibr10-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1016\/j.canep.2009.06.013"},{"key":"bibr11-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1093\/occmed\/kql171"},{"key":"bibr12-0748233720923504","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4878(99)00110-6"},{"key":"bibr13-0748233720923504","unstructured":"Egyptian Environmental Affairs Agency.
