    A nomogram to predict early hematoma expansion of hypertensive cerebral hemorrhage

    by Si Hu, WenGuo Sheng, Yi Hu, Qiang Ma, Bin Li, RuiZhang Han

    Early hematoma expansion of hypertensive cerebral hemorrhage is affected by various factors. This study aimed to clarify the risk factors and develop a nomogram to predict early hematoma expansion. A retrospective analysis was carried out in patients with hypertensive cerebral hemorrhage admitted to our institution between January 1, 2012 and December 31, 2018; the patients were divided into 2 groups according to the presence of early hematoma expansion. Univariate and multivariate analyses were performed to analyze the risk factors of hematoma expansion. The nomogram was developed based on a multivariate logistic regression model, and the discriminative ability of the model was analyzed. A total of 477 patients with hypertensive cerebral hemorrhage and with a baseline hematoma volume <30 ml were included in our retrospective analysis. The hematoma expansion rate was 34.2% (163/477). After multivariate logistic regression, 9 variables (alcohol history, Glasgow coma scale score, total serum calcium, blood glucose, international normalized ratio, hematoma shape, hematoma density, volume of hematoma on initial computed tomography scan, and presence of intraventricular hemorrhage) identified as independent predictors of hematoma expansion were used to generate the nomogram. The area under the receiver operating characteristic curve of the nomogram was 0.883 (95% confidence interval 0.851–0.914), and the cutoff score was −0.19 with sensitivity of 75.5% and specificity of 87.3%. The nomogram can accurately predict the risk of early hematoma expansion.


  • Clinical features and prognostic factors of WHO II and III adult spinal meningiomas: analysis of 25 cases in a single center

    by Jingliang Ye, Guoguang Lv, Jun Qian, Junle Zhu, Ruizhang Han, Chun Luo

    Spinal World Health Organization (WHO) II and III meningiomas are relatively rare, and often associated with great clinical aggressiveness and poor overall survival. There are controversies over factors affecting the prognosis of this disease. The aim of this retrospective study was to evaluate factors that may affect the therapeutic outcome and prognosis of adult high-grade spinal meningiomas by reviewing the medical records of 25 patients who were surgically treated in our hospital between 2001 and 2014. Univariate and multivariate analyses were performed to identify prognostic variables relative to patient and tumor characteristics, and treatment modalities. All 25 patients (14 men and 11 women; mean age 46.6 ± 16.1 years) underwent surgical resection. Local recurrence was occurred in 13 (52.0 %) patients, and 10 (40.0 %) patients died during the follow-up periods. The 5-year recurrence rate was 60.0 % and the 5-year survival rate was 68.0 %. The results of statistical analysis suggested that Simpson resection grade and the number of involved segments were prognostic factors related to progression-free survival and that sex, age, preoperative Frankel score, the number of involved segments and WHO grade were closely correlated with survival. Furthermore, we confirmed that the number of involved segments was the major independent factor affecting recurrence of patients with adult spinal high-grade meningiomas, and that sex, age and WHO grade were prognostic factors affecting survival but not recurrence.
