Abstract

Introduction: Lung cancer remains the leading cause of cancer-related death worldwide, with non–small cell lung cancer (NSCLC) accounting for approximately 85% of cases. Gefitinib is a tyrosine kinase inhibitor frequently used in NSCLC with favorable outcome. However, many patients develop severe adverse effects which might be influenced by genetic variability. Therefore, we aim to systematically review the gene variants and its association with adverse effects of gefitinib in NSCLC patients. Methods: A systematic search was conducted according to PRISMA guidelines across PubMed, Scopus, and Cochrane. Studies investigating the association between genetic variations with adverse effects following gefitinib in NSCLC were included. Extracted data encompassed study and patient characteristics, adverse effects, and identified gene variations. Risk of bias was assessed using the RoB-2 for randomized trials and Newcastle–Ottawa Quality Assessment Scale for cohort and case–control studies. Results: Nineteen studies involving 2.087 patients were included, with Japanese populations being the most studied. Polymorphisms in EGFR and ABCG2 were among the most studied genes. Rash, diarrhea, and hepatotoxicity are the most common adverse effects reported. Poor metabolizers of CYP2D6 and CYP3A53/3, and variations in ABCG2, ABCB1, and EGFR were associated with higher incidence of adverse effects. However, several studies demonstrated no associations between gene variations with adverse effects.  Conclusion: Genetic variations in ABCG2, ABCB1, CYP2D6, CYP3A53/3, and EGFR  may influence gefitinib-associated adverse effects, highlighting the need of pharmacogenomic testing to guide personalized treatment and improved patient safety.

Abstract

Introduction: Lung cancer remains the leading cause of cancer-related death worldwide, with non–small cell lung cancer (NSCLC) accounting for approximately 85% of cases. Gefitinib is a tyrosine kinase inhibitor frequently used in NSCLC with favorable outcome. However, many patients develop severe adverse effects which might be influenced by genetic variability. Therefore, we aim to systematically review the gene variants and its association with gefitinib-related adverse effects in NSCLC patients, as well as investigate the biological process involved. Methods: A systematic search was conducted according to PRISMA guidelines across PubMed, Scopus, and Cochrane. Studies investigating the association between genetic variations with gefitinib-related adverse effects in NSCLC were included. Risk of bias was assessed using the Cochrane RoB-E. Extracted data encompassed study and patient characteristics, adverse effects, and gene variations. Significant genes identified from included studies were analyzed through PPI network analysis, and the hub proteins found were visualized through Chimera. Results: Sixteen studies involving 1,176 patients were included, with Japanese populations being the most studied. Gene variants of CYP2D6, CYP3A4, ABCB1, ABCG2, EGFR, FOXO3, IKBKB, and AKT1 were found to be associated with adverse effects such as hepatotoxicity, skin rash, and diarrhea among NSCLC patients. Metabolism and inflammatory pathways might be involved in gefitinib-related adverse effects. Conclusion: Genetic variations in CYP2D6, CYP3A4, ABCB1, ABCG2, EGFR, FOXO3, IKBKB, and AKT1 may influence gefitinib-associated adverse effects, highlighting the need of pharmacogenomic testing to guide personalized treatment and improved patient safety.
