Prognostic evaluation of serum long non-coding RNA H19 for endoscopic keyhole surgery or craniotomy in glioma

Our study aims to explore the effect of serum long non-coding RNA (lncRNA) H19 level on the long-term prognosis of endoscopic keyhole surgery or craniotomy for glioma.

A total of 264 glioma patients were selected. Patients were randomly divided into the Craniotomy-high H19 group, the Craniotomy-low H19 group, the Endoscopic keyhole surgery-high H19 group and the Endoscopic keyhole surgery-low H19 group.

Compared with adjacent tissues (5.19 ± 1.42), H19 level in cancer tissues (7.45 ± 1.60) and serum (6.44 ± 1.57) was significantly increased (P < 0.05). Compared with serum, H19 level in cancer tissues was significantly increased (P < 0.05). Pearson correlation analysis found that the relative expression level of serum H19 in glioma patients was positively correlated with cancer tissues (r_Pearson = 0.547, P < 0.001), but had no significant correlation with adjacent tissues (r_Pearson = 0.126, P  =  0.207). The expression of H19 in serum was significantly related to WHO grade (r_Pearson = 0.514, P < 0.001). Compared with the Endoscopic keyhole surgery-high H19 group and the Endoscopic keyhole surgery-low H19 group, the survival rate of patients in the Craniotomy-high H19 group (χ² = 17.115 and log-rank P < 0.001; χ² = 18.406 and log-rank P < 0.001) and the Craniotomy-low H19 group was significantly reduced (χ² = 15.007 and log-rank P < 0.001; χ² = 16.121 and log-rank P < 0.001). Cox regression results showed that serum H19 level, craniotomy and WHO grade were risk factors for glioma. When H19 level was lower than 6.28, the 30-month survival rate of patients with the endoscopic keyhole surgery was 100%.

For patients with low H19 level (<5.36), both endoscopic keyhole surgery and craniotomy are available, otherwise, endoscopic keyhole surgery is more recommended.
