Objective: Long noncoding RNAs (lncRNAs) are key regulators during
ovarian cancer initiation and progression and are involved in mediating autophagy. In this study, we aimed to develop a prognostic autophagy-related
lncRNA signature for
ovarian cancer. Methods: Autophagy-related abnormally expressed lncRNAs were screened in
ovarian cancer with the criteria values of |correlation coefficient| > 0.4 and p < 0.001. Based on them, a prognostic
lncRNA signature was established. The Kaplan-Meier overall survival analysis was conducted in high- and low-risk samples in the training, verification, and entire sets, followed by receiver operating characteristics (ROCs) of 7-year survival. Multivariate Cox regression analysis was used for assessing the predictive independency of this signature after adjusting other clinical features. The associations between the risk scores and immune cell infiltration, PD-L1 expression, and sensitivity of
chemotherapy drugs were assessed in
ovarian cancer. Results: A total of 66 autophagy-related abnormally expressed lncRNAs were identified in
ovarian cancer. An autophagy-related
lncRNA signature was constructed for
ovarian cancer. High-risk scores were indicative of poorer prognosis compared with the low-risk scores in the training, verification, and entire sets. ROCs of 7-year survival confirmed the well-predictive efficacy of this model. Following multivariate Cox regression analysis, this model was an independent prognostic factor. There were distinct differences in infiltrations of immune cells, PD-L1 expression, and sensitivity of
chemotherapy drugs between high- and low-risk samples. Conclusions: This study constructed an autophagy-related
lncRNA signature that was capable of predicting clinical outcomes and also therapeutic responses for
ovarian cancer.
