Abstract

Purpose: Individual responses to platinum-based treatment for Non-Small Cell Lung Cancer (NSCLC) are influenced by genetic polymorphisms, including Single Nucleotide Polymorphisms (SNPs). This study aimed to explore the role of ERCC2 in the Nucleotide Excision Repair (NER) pathway for platinum-based chemotherapy in NSCLC. While is widely studied, data for Southeast Asian populations are lacking. Addressing this gap could improve personalized treatment strategies for NSCLC in this demographic.

Patients And Methods: This study recruited 82 NSCLC patients with wildtype mutations of at Dr. H.A. Rotinsulu Lung Hospital, Bandung, and Dharmais Cancer Hospital, Jakarta. Data were collected prospectively from whole blood samples and medical records, while the effectiveness of chemotherapy was assessed by evaluating the response using RECIST 1.1 criteria on fourth cycle of chemotherapy.

Results: The results of this study showed the presence of genotype variation among the subjects, with frequency distribution as follows: AA genotype (82.9%), AC genotype (15.9%), and CC genotype (1.2%). The analysis of the association between rs13181 CC + AC versus AA with RECIST 1.1 yielded an odds ratio (OR) of 1.042 (95% CI: 0.292-3.715; p=0.950). A multivariate analysis that included cancer stage and chemotherapy regimen as additional variables produced an adjusted odds ratio (aOR) of 0.970 (95% CI: 0.263-3.568; p=0.963).

Conclusion: This study did not find statistically significant associations between rs13181 polymorphisms and chemotherapy responses. However, this research highlights the presence of genetic variation within the Indonesian population, with the AA genotype being the most prevalent, which may influence chemotherapy responses. The results provided preliminary data and lay the foundation for future comprehensive cohort observational investigations.
