| Abstract |
Objective
Benign brain tumors are commonly found in elderly. It has been known that elderly patients tend to carry higher rate of comorbidities
which result in increased operative risks. But only few reports have been made analyzing the post-operative complication and prognosis
of benign brain tumor surgery in elderly patients. In this study, we analyzed the preoperative conditions of the patient and the results of the
treatment to find out whether the surgical treatment of the benign brain tumor is beneficial to the patients.
Methods
Retrospective analysis was made for patients aged 65 or more than 65 with benign brain tumors who received surgical resection.
Patient-related factors including age, sex and preexisting comorbidities and tumor-related factors including complexity of the surgery were
analyzed to show its relationship with the postoperative Karnofsky Performance Score (KPS) at six months after surgery.
Results
Among 56 patients enrolled for the study, 48 patients (85.7%) showed improved or stationary KPS postoperatively compared to that
of before the operation. 8 patients (14.3%) showed aggravated KPS after the operation. Difficulty of the surgery was related with the patient’s
postoperative KPS but age, sex and preexisting comorbidities were not related with the postoperative KPS.
Conclusion
Tumor-related factor is important in surgery of benign brain tumor in elderly patients. Preoperative comorbidities of the patients
did not affect the result of the operation and the patient’s functional outcome. In the era of the advanced anesthetic and microsurgical technique,
old age is not risk factor for the benign brain tumor surgery. |
