The Correlation between the Expression of Long Non-coding RNA UCA1 andthe Radio-sensitivity of Esophageal Squamous Cell Carcinoma Patients

Objective To explore the correlation between the expression of long non-coding RNA(lncRNA) UCA1 and radiotherapy sensitivity in patients with esophageal squamous cell carcinoma. Methods A total of 80 patients with esophageal squamous cell carcinoma admitted to the Affiliated Tumor Hospital of Xinjiang Medical University from February 2020 to February 2022 were selected as the esophageal cancer group, and 50 subjects who underwent health examinations in our hospital during the same period were selected as the control group.Real time fluorescence quantitative PCR was used to detect the plasma lncRNA UCA1 expression levels of all subjects and compare them.The relationship between lncRNA UCA1 levels and clinical pathological indicators in esophageal cancer patients, as well as their relationship with radiation sensitivity, was analyzed. Results The plasma lncRNA UCA1 levels in the esophageal cancer group were higher than those in the control group, and the difference was statistically significant(P0.05);The plasma lncRNA UCA1 levels in patients with TNM stage Ⅲ+Ⅳ esophageal squamous cell carcinoma were higher than those in patients with stage Ⅰ+Ⅱ, and the difference was statistically significant(P2.31) showed a significant decrease in radiotherapy sensitivity(P
