Lung Cancer at a University Hospital: Epidemiological and Histological Characteristics of a Recent and a Historical Series

Epidemiological and Clinicopathological Characteristics of Lung Cancer in a Teaching Hospital in Iran

“…The mean age of our patients was 65.7 years (SD=11.2) years which was close to other studies previously reported from Iran (Ehteshamifar et al, 2001;Hosseini et al, 2009;Tarrahi et al, 2009;Zahir and Mirtalebi, 2012;Ghobadi et al, 2013). This finding was also similar to those found in several studies carried out in other countries (Santos-Martinez et al, 2005;Missaoui et al, 2011;Demirci et al, 2013;El-Basmy, 2013). Clinically, similar to other studies, the majority of patients seeking medical advice complained of cough, dyspnea, chest pain, and hemoptysis (Ehteshamifar et al, 2001;Ghobadi et al, 2013;Mandal et al, 2013).…”

“…The contribution of smoker women in our study was 15.8% .This contribution was 13-14% (Ehteshamifar et al, 2001;Hosseini et al, 2009) or 38.7% (Tarrahi et al, 2009) in other Iranian studies. Meanwhile, the propportin of female smokers in some reports from other countries was much higher than what we found, including 34.1% in Turkey (Demirci et al, 2013), 38% in Spain (Santos-Martinez et al, 2005), and 68% in India (Mandal et al, 2013). A probable reason for this could be a lower rate of smoking in Iranian women than those countries.…”

“…Smoking is the most common risk factor of lung cancer and associated with these 3 types of malignancies however, this association is higher with SCC and SC than AC. On the other hand, AC in women, regardless of smoking, is higher than men as reported in a study from Spain in which AC in women ranked first with an incidence rate of 56.2% (Santos-Martinez et al, 2005). Therefore, given the low percentage of smoker female patients in our study, it was expected AC to have a higher contribution than SCC which failed to achieve.…”

Role of Bronchial Brush Cytology in Diagnosis of Central Bronchial Carcinoma

“…This result was also in agreement with other studies. 24,25.26 While Shah et al 27 reported the mean age of their patients with bronchial carcinoma was 45.6 years which was lower than the present study and Santos-Martínez et al 28 reported that the mean age was 67.1 (± 11.1), which was higher than the present study.…”

“…Similar male preponderance of bronchial carcinoma were reported in several other studies. 3,23,28,29 Male-Female ratio in this study is markedly increased which can be explained by some reasons like small sample size, less reporting of female patients in a tertiary care hospital and less common smoking habit in female in our country.…”
