Epidemiologic and Histopathologic Feature of Lung Cancer in Central Iran (2012-2018)

Abstract

Background: Lung cancer is one of the common causes of death worldwide.Although the incidence rate of lung cancer in Western countries is decreasing, it presents a growing trend in developed countries. Since there is no accurate enough information about the epidemiological and Histopathologic features of lung cancer in central Iran, Isfahan, we were motivated to conduct this research. Materials and Methods: This was a descriptive, cross-sectional study carried out in central Iran, Isfahan. All demographic, histopathological and clinical data of the lung cancer patients registered in MACSA, a referral charity-based cancer center in central Iran, was analyzed within 2012-2018 using SPSS v.22 software.Results: Altogether 260 patients with lung cancer were included in this study from 6127 cancer patients registered within 2012-2018 (4.2%). Out of them, 66.2% were men, and 18.8 % of the patients were alive at the time of the study. The mean age of the patients at diagnosis was 61.56 (SD=14.11, range: 9-93). Altogether, 63.1% of patients had metastasis of whom 57.6% were in stage IV at diagnosis. The Frequency of different types of lung cancer was 36.9% adenocarcinomas, 14.2% squamous cell Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 8 April 2020 carcinoma, 9.6% bronchogenic carcinoma and 8.1% small cell lung cancer, respectively. Altogether, 128 cases were smokers with an average 35.45 ± 14 packyears. Only in 36.2% of the patients, the diagnostic and therapeutic biomarkers had been checked, and CK7 was positive in 88.9% of the cases in which the biomarker had been checked. Conclusion:Despite to similar Iranian studies, the most common histopathologic type of lung cancer among the patients was adenocarcinoma that it may be attributed to the lower consumption of smoking in our population and their different genetic context. Molecular biomarkers had been checked in a small portion of the patients.More education of the clinicians along with the development of cancer molecular testing may lead to promote the personalized-based approach.

Opium as a carcinogen: A systematic review and meta-analysis

“…It is the third most common cause of death in Iran [2]. The incidence of cancer is increasing in developing countries due to lifestyle changes such as rises in tobacco consumption, which is the most important risk factor for malignancies and the cause of 22% of cancer-related deaths [1,3]. However, cancer cannot be addressed as a mono-factorial disease or even a multifactorial disorder with completely known risk factors.…”
