Background: Dissection of brain surface adhesions during recurrent glioma surgery carries a risk of injury to cortical vessels and important surface vessels. We present our experience with the use of BioD film, a biocompatible amniotic membrane implant, to help prevent postoperative adhesions. We describe a novel method for preventing postoperative adhesions after high-grade glioma surgery using BioD film.
Methods: Amniotic sac implants were laid on the brain surface after resection of gliomas located near major surface arteries (sylvian fissure) and major veins (parasagittal convexity). Seven cases involved reoperation for tumor recurrence.
Results: In all 7 of the cases requiring reoperation, a new arachnoid-like surface layer was formed without any dural adhesions. The newly formed layer allowed for easy and simple dissection and mobilization of surface vessels while avoiding any trauma to the cortex.
Conclusions: Amniotic sac implants have a promising role in preventing most surgical brain adhesions associated with recurrent glioma surgery, reducing the risks of cortical vessel and tissue injury.

Background: Radiotherapy plus temozolomide followed by adjuvant temozolomide was the standard treatment for high-grade gliomas. This study aimed to explore the effectiveness and safety of the addition of apatinib in patients with high-grade gliomas after surgery.
Methods: In this retrospective cohort study, patients with high-grade glioma [World Health Organization (WHO) grade III or IV] treated with apatinib and concurrent chemoradiotherapy (cCRT) after surgery from October 2017 to February 2021 were reviewed.
Gastrin-Releasing Peptide Receptor Targeting PET/CT With 68Ga-NOTA-RM26 in the Assessment of Glioma and Combined Multiregional Biopsies.

From the Department of Nuclear Medicine, State Key Laboratory of Complex Severe and Rare Diseases, Beijing Key Laboratory of Molecular Targeted Diagnosis and Therapy in Nuclear Medicine, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.
Purpose: The aim of this study was to investigate the value of 68Ga-NOTA-RM26 (68Ga-RM26), a gastrin-releasing peptide receptor-targeting antagonist labeled with the radionuclide 68Ga, in the diagnosis of high-grade gliomas and in combination with multiregional biopsies using PET/CT.
Patients And Methods: After institutional review board approval and informed consent, a total of 35 patients with suspected glioma lesions were enrolled in this study. All patients underwent 68Ga-RM26 PET/CT scans within 2 weeks before surgery.

Spinal cord gliomas are commonly malignant tumors of the spinal cord, leading to a high rate of disability. However, uniform treatment guidelines and comprehensive data on spinal cord gliomas remain limited due to the lack of suitable preclinical animal models. Developing a simple and reproducible animal model has become essential for advancing basic and translational research.
