Abstract:
Objective To investigate the correlation between clinical features and prognosis of patients with neurofibromatosis type 2(NF2)after operation.Methods The clinical features and prognosis of sixty patients with neurofibromatosis type 2(NF2)from 2000 to 2013 in Xi′an No.1 Hospital were analyzed.Cox proportional hazards regression model was used for variable analysis.Results The patients were followed up for 1-188 months,53 patients survived(88.3%,53/60),and 7 patients died(11.7%,7/60).Single factor analysis showed that the first symptom age,age of diagnosis,intracranial meningioma and spinal cord tumor were related to the prognosis of the patients(P<0.05).However,gender,genetic factors,skin lesions,eye diseases, postoperative hearing improvement and relief of dizziness after surgery were not correlated with the prognosis of patients(P>0.05).Spinal cord tumors or intracranial meningiomas were the independent risk factors for the prognosis of NF2 patients(P=0.042,0.037,95%CI=0.021-2.069,0.587-2.543,RR=2.475,3.663).The first symptoms age,age of diagnosis,ocular lesions were the risk factors for the occurrence of spinal cord tumors and intracranial meningiomas(P<0.05).Conclusion NF2 has many clinical symptoms,accompanied by spinal cord tumor and intracranial meningioma,which are the important prognostic factors in patients with poor prognosis.
