Abstract
To investigate the expression of Circ_cgga162 in serum of mantle cell lymphoma (MCL) patients and analyze its potential as a prognostic biomarker. The expression of Circ_cgga162 in 86 cases of mantle cell lymphoma and 50 cases of lymph node reactive hyperplasia (RH) were detected by real-time quantitative polymerase chain reaction (qRT-PCR). The relationship between the expression of Circ_cgga162 and clinicopathological features was analyzed by univariate analysis. The relationship of Circ_cgga162 expression with progression-free survival time and overall survival time was analyzed by Kaplan-Meier. The relationship between expression of Circ_cgga162 and prognosis of patients was analyzed by univariate and multivariate analysis. The expression level of Circ_cgga162 in MCL patients was significantly higher than that in control (RH) group (P＜0.01). The expression of Circ_cgga162 not correlated with age, gender, B symptoms and LDH (all P＞0.05), but correlated with the expression of MCL International Prognostic Index (IPI), Ann Arbor stage, bone marrow infiltration and Ki67 (all P＜0.05). In addition, Kaplan-Meier analysis showed that the progression-free survival time and overall survival time of the MCL patients with high expression of Circ_cgga162 were significantly shorter than those of the MCL patients with low expression (P＜0.01). Univariate analysis showed that Ann Arbor stage, Circ_cgga162 expression, MIPI, bone marrow infiltration and Ki67 were the prognostic factors for MCL patients (all P＜0.05). Multivariate Cox regression analysis showed that Ann Arbor stage, Circ_cgga162 expression and MIPI were independent factors affecting the prognosis of MCL patients (all P＜0.05). Circ_cgga162 is highly expressed in serum of patients MCL, which relates with the prognosis of MCL patients. Circ_cgga162 can be used as a potential prognostic marker and therapeutic target for MCL patients.
