CircPVT1 was found to be upregulated in various cancers and was investigated for its clinical significance in NSCLC patients receiving cisplatin combined with gemcitabine chemotherapy. The study showed that circPVT1 expression decreased after chemotherapy and was associated with chemotherapy sensitivity.
Objective: CircPVT1 was identified as a tumor-promoted circRNA that is upregulated in several cancers. We researched clinical significance of circPVT1 in patients with non-small cell lung cancer (NSCLC) who received cisplatin combined with gemcitabine chemotherapy. Methods: Reverse transcriptase polymerase chain reaction assays were performed to detect circPVT1 expression in 96 patients with NSCLC. In addition, Kaplan-Meier methods were performed to analyze survival of patients with NSCLC. Results: There is no significant difference between circPVT1 and age, sex, histologic type, lymphatic invasion, or vascular invasion in patients with NSCLC and there is significant difference between circPVT1 and differentiation or p-TNM stage in patients with NSCLC. In addition, after cisplatin combined with gemcitabine chemotherapy, circPVT1 expression was decreased, and circPVT1 expression in the chemotherapy-resistant group was higher than in the chemotherapy-sensitive group. Survival of patients with NSCLC was associated with high circPVT1 expression. Conclusions: Our study revealed the clinical significance of circPVT1 in NSCLC after cisplatin combined with gemcitabine chemotherapy. After treatment, circPVT1 expression was decreased and circPVT1 expression in chemotherapy-resistant patients was higher than in chemotherapy-sensitive patients. Decreased circPVT1 expression in chemotherapy-sensitive patients is more notable than in chemotherapy-resistant patients. Therefore, it is possible to determine the effect of therapy after receiving chemotherapy by detecting the expression of circRNA in serum.
