Introduction: Cervical cancer (CC) is one of the most common types of cancer in women and is closely associated with persistent infection by oncogenic types of the human papillomavirus (HPV). The World Health Organization (WHO) aims to eradicate CC as a public health problem by 2100. However, challenges such as vaccination limitations and the spread of misinformation hinder vaccine uptake, despite its proven efficacy (1). The prognosis of CC depends on the stage of the disease and becomes more unfavorable in advanced stages. Therefore, the search for effective biomarkers for diagnosis and monitoring is essential to improve early detection and treatment follow-up. Objectives: This study aimed to explore the role of long non-coding RNAs (lncRNAs) in CC, focusing on identifying and characterizing relevant lncRNAs, understanding their regulatory mechanisms and molecular interactions, and analyzing their expression patterns in patients with different responses to chemoradiotherapy. Methods: A retrospective observational study was conducted, analyzing RNA samples from 31 patients treated at the Mário Penna Institute (2017-2019) (2). The expression of lncRNAs was analyzed by RNA-seq, and molecular interactions were investigated using bioinformatics tools such as AnnoLnc2 and ClusterProfiler. Decision tree analyses and Kaplan-Meier survival curves were performed to assess the association between lncRNAs and clinical outcomes. Results: Among the 417 differentially expressed lncRNAs identified, three stood out: ENSG00000267838, ENSG00000266340, and FRMD6-AS1. High expression of ENSG00000267838 and ENSG00000266340 correlated with treatment resistance and a worse prognosis, while their low expression indicated a better therapeutic response. Kaplan-Meier analysis showed that high expression of these lncRNAs was associated with shorter progression-free survival. The decision tree model demonstrated high accuracy (87.09%) in distinguishing between responder and non-responder patients. Conclusions: Three lncRNAs, ENSG00000267838, ENSG00000266340, and FRMD6-AS1, were identified as being positively associated with non-response to chemoradiotherapy and poorer progression-free survival in CC patients. Specifically, the upregulation of lncRNA ENSG00000267838 was linked to treatment resistance, while its downregulation was associated with a favorable response to chemoradiotherapy.
