For our study, we sought to construct a risk model that could guide the prognosis of ovarian cancer patients, which consisted of five m7G-related lncRNAs (KRT7-AS, USP30-AS1, ZFHX4-AS1, ACAP2-IT1, and TWSG1-DT) could not only serve as an independent prognostic factor for ovarian cancer patients, but also it was indicative of instructing and predicting the overall survival of ovarian cancer. This evidence concerns the gene TWSG1 and ovarian carcinoma.
