Postoperative seizure in high grade glioma patients treated with BCNU wafers. A mono-institutional experience.
Trial report in Journal of neuro-oncology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 4 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Anticonvulsant therapy is usually recommended before surgery in all patients affected by high grade glioma who are planned to be treated with Carmustine 1,3-bis [2 chloroetyl]-1-nitrosurea, or BCNU) wafers. In fact, phase III studies have reported a risk of seizures higher than 30% in this group of patients. The aim of the study was the evaluation of rate type time of occurrence of seizures in BCNU-treated patients in the postoperative period as well as the investigation into possible risk factors for seizure occurrence in this population. From April 2007 to September 2010, 55 patients underwent surgical removal of malignant glioma and BCNU wafers implantation at the Department of Neurosurgery of Padova. All patients were given antiepileptic prophylaxis for 3 months after surgery. Clinical data (including preoperative seizure history), radiological data, surgical treatment, antiepileptic treatment were retrospectively reviewed. Nine percent of the patients treated with BCNU wafers presented seizures in the postoperative course. Seizures were partial in 80% of cases; they occurred within 30 days after surgery and in 80% of cases within the first 7 days. Patients with preoperative seizures presented more frequently postoperative epilepsy than patients who were preoperatively seizure-free [P = 0.0006; OR = 48 (2,4;945)]. Postoperative seizures were more common among patients affected by one or more wafers related adverse event than among patients without adverse events [P = 0.006; OR = 21 (2,06;213)]; however, they did not appear associated to the number of implanted wafers. Patients with a sub-therapeutic level of AED at the seventh day after surgery presented a higher seizure occurrence [P = 0.02; OR = 11 (1,5;79,8)]. In our experience, postoperative seizures in BCNU-treated patients were less frequent than expected. Careful patient selection and postoperative monitoring could probably play a role in order to decrease seizure occurrence.
