Cervical cancer is a tumor with the second highest morbidity and mortality in the world, and it is also the most common cancer and the eighth lethal factor among malignant tumors in Chinese female. This study aimed to identify long noncoding RNAs (lncRNAs) that related to diagnosis and prognosis in cervical cancer to improve early diagnosis and treatment. First, we extracted transcriptome profilings of cervical cancer samples from the cancer genome atlas (TCGA) database, and then extracted the lncRNAs and mRNAs expression profiles. Based on the lncRNAs expression profiles of test set, we screened lncRNAs that related to progression of cervical cancer tumors. We found six lncRNAs associated with tumor progression in cervical cancer patients, in which five lncRNAs have highly similar expression patterns but the other one has the opposite expression pattern. We found that these six lncRNAs might be related to keratinization and immunity by enrichment analysis, and two of them (AC126474 and C5orf66‐AS1) were associated with prognosis in patients with cervical cancer. And these results were validated using the validation set. Overall, we identified six lncRNAs that played an important role in the development of cervical cancer, and two of them might be associated with the prognosis of cervical cancer, which provides new insight into the diagnosis and treatment of cervical cancer.
