Adenocarcinoma among Patients Diagnosed with Lung Cancer in a Tertiary Care Centre: A Descriptive Cross-sectional Study

Introduction: Lung cancer is the leading cause of cancer deaths all over the world and adenocarcinoma is the most common type. Diagnosis is made usually at an advanced stage of lung cancer in patients, making it nearly impossible to cure. The aim of this study is to find out prevalence of adenocarcinoma among patients diagnosed with lung cancer in a tertiary care centre. Methods: A descriptive cross-sectional study was carried out in the Department of Pulmonary Medicine of a tertiary care centre among 69 patients from October, 2018 to September, 2019. Ethical approval was taken from the Institutional Review Committee of a tertiary care hospital (Reference number: 54/2018). A convenience sampling technique was used. Data were entered and analysed using the Statistical Package for the Social Sciences version 21.0. Point estimate at 90% Confidence Interval and descriptive statistics were interpreted as frequency, percentage, or as mean and standard deviations. Results: Among 69 lung cancer patients, adenocarcinoma was seen in 27 (39.13%) (29.47-48.79 at 90% Confidence Interval). Out of 27, 10 (37.04%) were male and 17 (62.96%) were female. Chronic obstructive pulmonary disease was the major comorbidity seen among 17 (62.96%) patients. Conclusions: The prevalence of adenocarcinoma was similar to other studies done in similar settings.
