Abstract

Increased research efforts have demonstrated that lncRNAs are associated with multiple head and neck tumors and play important roles in cancer. We previously found that RP11-169D4.1-001 plays a tumor-suppressive role in laryngeal cancer, but its function in human hypopharyngeal squamous cell carcinoma (HSCC) remains unknown. Thus, this research aimed to analyze the relationship between RP11-169D4.1-001 expression and HSCC clinicopathological features.Real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the expression of RP11-169D4.1-001 in 70 pairs of HSCC and adjacent normal tissues.The expression level of RP11-169D4.1-001 in HSCC tissues was significantly lower than that in adjacent normal tissues (P = .001). The expression of RP11-169D4.1-001 had no significant relationship with tumor differentiation, stage, smoking, drinking, age, tumor location, or treatment. RP11-169D4.1-001 expression was associated with T category (P = .008) and lymph node metastasis (P = .001). Survival data were assessed by Kaplan-Meier curves. Patients with high RP11-169D4.1-001 expression were found to have a shorter overall survival than patients with low RP11-169D4.1-001 expression. Multivariate analysis also indicated that target RNA was an independent factor for prognosis. The ROC curve was constructed to clarify the diagnostic value of RP11-169D4.1-001.RP11-169D4.1-001 may serve as a new biomarker and potential drug target and can be used as a new biomarker and a potential drug target for the detection and treatment of hypopharyngeal cancer, respectively. Furthermore, RP11-169D4.1-001 expression may be an independent prognostic factor affecting the survival of hypopharyngeal cancer patients.
