Abstract

Objective: This study aimed to analyze CD 133 stem cell biomarker levels in serum and bronchial lavage, as well as correlate these levels with treatment responses and outcomes in patients with advanced-stage NSCLC. Methods: This is a cross-sectional, observational, and analytical study that analyzed data from NSCLC patients and control at Dr. Wahidin Sudirohusodo Hospital, Makassar. CD 133 levels in serum and bronchial lavages were quantified using ELISA and correlated with treatment responses assessed by RECIST 1.1 criteria. Result: A total of 118 participants were used, with 66 being NSCLC patients and 52 as the control. The results showed significant differences in CD 133 serum and bronchial lavage levels (p<0.05). Moreover, NSCLC patients with advanced tumors (T4) had higher CD 133 levels in bronchial wash (p<0.05). The bronchial wash CD 133 test showed higher sensitivity (83.6%) and specificity (79.2%) compared to serum CD 133. Even though CD 133 levels were not significantly correlated with treatment response, they were higher in patients with advanced tumor stages. Conclusion: CD 133 levels were significantly higher in bronchial wash samples from NSCLC patients with advanced tumors (T4). Also, there was a positive correlation between CD 133 levels in bronchial wash and serum. These results emphasized the potential of CD 133, particularly in bronchial wash, as a valuable diagnostic tool for NSCLC.
