Summary:Purpose: Surgical treatment of refractory temporal lobe epilepsy (TLE) is promising for selected patients, but only little experience has been acquired in operating on older patients, especially with limited resections. We intend to delineate clinical and surgical factors influencing outcome in patients older than 50 years at operation and to compare the results with those of a younger patient cohort.Methods: Fifty-two patients older than 50 years were operated on for intractable mesial or combined mesiolateral TLE between 1991 and 2002. The mean age at operation was 55 years, and the mean duration of epilepsy was 33 years. Forty selective amygdalohippocampectomies (33 for hippocampal sclerosis, seven for removal of a mesiotemporal lesion), five lateral temporal lesionectomies plus amygdalohippocampectomy, and seven anterior temporal lobectomies were performed. Eleven (21%) patients had undergone invasive presurgical video-EEG monitoring. The mean follow-up period was 33 months. We compared the results with those of a younger cohort operated on in the same time period.Results: Thirty-seven older patients attained complete seizure control (71% class I), and 10 patients had only rare postoperative seizures (19% class II). Four patients improved >75% (8% class III), and one patient did not improve (2% class IV). The same rate of seizure control was attained by 11 patients older than 60 years at surgery. These results were not significantly different from those in a younger patient group. A trend toward better seizure control was noted in 16 patients with an epilepsy duration of <30 years (all class I or II), and in 20 patients with a seizure frequency of fewer than five seizures per month (all class I or II). No mortality resulted from a total of 65 diagnostic and therapeutic procedures. A 3.8% permanent neurologic morbidity (dysphasia and hemiparesis) was noted. Hemianopia occurred in three (5.9%) patients. Neuropsychological testing revealed low preoperative performances and some gradual further deterioration after surgery.Conclusions: Results of surgery for TLE with mainly limited resections are promising in patients older than 50 years and older 60 years, despite the long seizure history. As expected, the risk of complications is somewhat higher compared with that in a younger control group. The impact of low neuropsychological performance is a concern.
Background
In recent years an increasing number of patients with cerebral metastasis (CM) have been referred to the neuro-oncology multidisciplinary team (NMDT). Our aim was to obtain a national picture of CM referrals to assess referral volume and quality and factors affecting NMDT decision making.
Methods
A prospective multicenter cohort study including all adult patients referred to NMDT with 1 or more CM was conducted. Data were collected in neurosurgical units from November 2017 to February 2018. Demographics, primary disease, KPS, imaging, and treatment recommendation were entered into an online database.
Results
A total of 1048 patients were analyzed from 24 neurosurgical units. Median age was 65 years (range, 21-93 years) with a median number of 3 referrals (range, 1-17 referrals) per NMDT. The most common primary malignancies were lung (36.5%, n = 383), breast (18.4%, n = 193), and melanoma (12.0%, n = 126). A total of 51.6% (n = 541) of the referrals were for a solitary metastasis and resulted in specialist intervention being offered in 67.5% (n = 365) of cases. A total of 38.2% (n = 186) of patients being referred with multiple CMs were offered specialist treatment. NMDT decision making was associated with number of CMs, age, KPS, primary disease status, and extent of extracranial disease (univariate logistic regression, P < .001) as well as sentinel location and tumor histology (P < .05). A delay in reaching an NMDT decision was identified in 18.6% (n = 195) of cases.
Conclusions
This study demonstrates a changing landscape of metastasis management in the United Kingdom and Ireland, including a trend away from adjuvant whole-brain radiotherapy and specialist intervention being offered to a significant proportion of patients with multiple CMs. Poor quality or incomplete referrals cause delay in NMDT decision making.
