Influencing factors of seizures in glioma patients and its relationship with recurrent epilepsy / 国际外科学杂志

ABSTRACT

Objective To analyze the influencing factors of epilepsy in patients with glioma,and to explore the relationship between the epileptic factors and the recurrence of epilepsy after surgery.Methods From January 2012 to December 2015,clinical data of 95 glioma patients in the Fifth Affiliated Hospital of Zhengzhou University were retrospectively analyzed,which were divided into two groups,including 54 cases with epilepsy and 41 cases without epilepsy,all patients were underwent tumor resection,to search and resect epilepsy lesions in patients with epilepsy,Follow-up using outpatient examination and telephone interview was performed to record seizure recurrence after operation,sort and analyze the clinical data of patients,to investigate the influencing factors of epileptic seizures,and the relationship between the factors associated with epileptic seizures and postoperative recurrence of epilepsy.The epileptogenic factors were analyzed using x2 test and multifactor Logistic regression model,epileptogenic factors and recurrent epilepsy after operation were analyzed usingx2 test.Results Logistic regression model showed that peritumoral edema ＞ 2 cm(OR =6.905,95％ CI2.787-17.106),low tumor pathological grade (0R =5.032,95％ CI1.696-14.931) were independent risk factors for epileptic seizures;Follow-up situations16 cases (13 cases of epilepsy group,3 cases of no epilepsy group) showed epileptic seizure in different time after the operation,preoperative epilepsy history,peritumoral edema were related to the recurrence of epileptic seizures in epilepsy group and the patients without epilepsy (x2 =2.940,3.049,all P ＜ 0.05),the pathological grade was related to the recurrence of epileptic seizures in epilepsy group (x2=4.774,P ＜ 0.05),however,it was not associated with the patients without epilepsy (x2 =0.060,P ＞ 0.05),and there was a correlation between the preoperative history of epilepsy and the postoperative recurrent seizures (x2 =4.672,P ＜ 0.05).Conclusions Peritumoral edema ＞ 2 cm and low tumor pathological grade are the factors that lead to epileptic seizures and postoperation epilepsy recurrence in glioma patients.It's expected to take some positive treatment to reduce epileptic seizures,we should pay special attention to glioma patients with epilepsy.
