Abstract
OBJECTIVE: This study aims to measure arsenic concentration in bronchoalveolar lavage fluid (BALF ) of newly diagnosed lung cancer and its corelation with clinical profiles. METHODS: This study is a cross-sectional study to identify arsenic levels in newly diagnosed lung cancer patients. Bronchoalveolar lavage fluid was taken during the bronchoscopy. Arsenic concentration was measured using an ICP-EOS spectrometer. RESULTS: Forty-two subjects who met inclusion criteria were recruited in this study. Arsenic metals were detected among 40% of subjects with mean, highest, and lowest values are 0.38 µg/L, 0.5 µg/L, and 0.3 µg/L, respectively. There is no significant difference between arsenic level and patients' demographic and clinical data. CONCLUSION: Arsenic was detected in BALF in majority of newly diagnosed lung cancer patients. Despite the insignificant relationship between arsenic level and patients characteristic, this results is evidence of which arsenic metal exposure in lung cancer during their lifetime and should raise public health awareness regarding mitigating the source of exposure and its potential as lung carcinogenic agent.
