INTRODUCTION: The most recent local study on the incidence of histological subtypes of all brain and spinal tumours treated surgically was published in 2000. In view of the outdated data, we investigated the presenting characteristics, histological subtypes and outcomes of adult patients who underwent surgery for brain or spinal tumours at our institution. METHODS: A single-centre retrospective review of 501 patients who underwent surgery for brain or spinal tumours from 2016 to 2020 was conducted. The inclusion criteria were (a) patients who had a brain or spinal tumour that was histologically verified and (b) patients who were aged 18 years and above at the time of surgery. RESULTS: Four hundred and thirty-five patients (86.8%) had brain tumours and 66 patients (13.2%) had spinal tumours. Patients with brain tumours frequently presented with cranial nerve palsy, headache and weakness, while patients with spinal tumours frequently presented with weakness, numbness and back pain. Overall, the most common histological types of brain and spinal tumours were metastases, meningiomas and tumours of the sellar region. The most common complications after surgery were cerebrospinal fluid leak, diabetes insipidus and urinary tract infection. In addition, 15.2% of the brain tumours and 13.6% of the spinal tumours recurred, while 25.7% of patients with brain tumours and 18.2% of patients with spinal tumours died. High-grade gliomas and metastases had the poorest survival and highest recurrence rates. CONCLUSION This study serves as a comprehensive update of the epidemiology of brain and spinal tumours and could help guide further studies on brain and spinal tumours.

The increasing number of long-term survivors of pediatric brain tumors requires us to incorporate the most recent knowledge derived from cognitive neuroscience into their oncological treatment. As the lesion itself, as well as each treatment, can cause specific neural damage, the long-term neurocognitive outcomes are highly complex and challenging to assess. The number of neurocognitive studies in this population grows exponentially worldwide, motivating modern neuroscience to provide guidance in follow-up before, during and after treatment. In this review, we provide an overview of structural and functional brain connectomes and their role in the neuropsychological outcomes of specific brain tumor types. Based on this information, we propose a theoretical neuroscientific framework to apply appropriate neuropsychological and imaging follow-up for future clinical care and rehabilitation trials.

Patients afflicted with low-grade glioma frequently suffer from seizures. The mechanisms for seizure initiation in these patients remain poorly understood. Tumor location is correlated with seizure initiation. However, these correlative studies rely on dichotomized data analysis which is based on arbitrary lobe assignments. As a result, the lesion-symptom correlation may be incorrectly interpreted. Categorizing patients according to tumor involvement in a single brain lobe might cause the neglect of important information, such as lesion location and lesion volume. Tumors that invaded more than one brain lobe may could be counted repeatedly. The anatomic correlation of the tumor-induced seizures is therefore difficult to be identified. Investigations based on voxel-wise quantitative lesion analysis could avoid the above statistical bias. According to the voxel-wise analysis, the increased seizure risks were identified for patients with low-grade gliomas that involved the left premotor area.

PURPOSE: Increasing number of older adults are receiving cancer surgeries especially for gastrointestinal cancers, which brings forth attention to age-related postoperative complication prevention. Postoperative delirium (POD) is a common complication that rises after surgical procedures involving general anesthesia, largely in the elderly population. Due to its sudden onset and fluctuating symptoms, POD often goes underdiagnosed and undertreated even though it may lead to various adverse outcomes. POD in GI cancer surgical elderly patients is poorly understood in terms of prevalence, pathophysiology, assessment, treatment and nursing management. We aimed to identify available literature and investigate study results to broaden our understanding of geriatric GI cancer POD. METHODS: The search process involved six databases to identify relevant studies abided by inclusion criteria. RESULTS: Eleven studies were selected for this review. Geriatric POD is closely related to frailty and surgical complications. Frailty increases vulnerability to surgical stress and causes cerebral changes that affect stress-regulating neurotransmitter proportions, brain blood flow, vascular density, neuron cell life and intracellular signal transductions. These conditions of frailty result in increased risks of surgical complications such as blood loss, cardiovascular events and inflammation, which all may lead to the POD. Mini Metal State Examination (MMSE), Confusion Assessment Method (CAM) and Delirium Rating Scale-revised-98 (DRS-R-98) are recommended for POD assessment to identify high-risk patients. CONCLUSION: The POD prevalence ranged from 8.2% to 51.0%. The multifactorial causative mechanism suggests nurses to identify highrisk elderly GI-cancer surgical patients by reviewing patient-specific factors and surgery-specific factors.

Fibromyalgia syndrome after comprehensive treatment of breast cancer is rare and seldom reported. Here we present a case of a 50-year-old female patient,who was admitted to the hospital because of generalized fibromyalgia for 3 months and brain metastasis after the right breast carcinoma surgery for 1 month, and the clinical diagnosis was brain metastasis from breast carcinoma combined with fibromyalgia syndrome. The fibromyalgia were relieved with proper symptomatic treatment but the patient eventually died of tumor progression.

PURPOSE: We aimed to evaluate the histologic and radiologic findings of vascular lesions after stereotactic radiosurgery (SRS) categorized as radiation-induced cavernous hemangioma (RICH). MATERIALS AND METHODS: Among 89 patients who underwent neurosurgery for cavernous hemangioma, eight RICHs from 7 patients and 10 de novo CHs from 10 patients were selected for histopathological and radiological comparison. RESULTS: Histologically, RICHs showed hematoma-like gross appearance. Microscopically, RICH exhibited a hematoma-like area accompanied by proliferation of thin-walled vasculature with fibrin deposits and infiltrating foamy macrophages. In contrast, CHs demonstrated localized malformed vasculature containing fresh and old clotted blood on gross examination. Typically, CHs consisted of thick, ectatic hyalinized vessels lined by endothelium under a light microscope. Magnetic resonance imaging of RICHs revealed some overlapping but distinct features with CHs, including enhancing cystic and solid components with absence or incomplete popcorn-like appearance and partial hemosiderin rims. CONCLUSION: Together with histologic and radiologic findings, RICH may result from blood-filled space after tissue destruction by SRS, accompanied with radiation-induced reactive changes rather than vascular malformation. Thus, the term "RICH" would be inappropriate, because it is more likely to be an inactive organizing hematoma rather than proliferation of malformed vasculature.

OBJECTIVETo propose a clinically practical and simple fiber tracking method for language pathways, and to explore its feasibility in preoperative planning for brain tumors adjacent to the language cortex.

METHODSDiffusion tensor imaging was examined in 18 healthy subjects and 13 patients with brain tumors adjacent to the language cortex between December 2013 and June 2014. The associated fibers of language pathways were reconstructed using a commercial software (Syngo workstation). Firstly, the feasibility of fiber tracking method for language pathways in healthy subjects were studied, and then its application was assessed in patients with brain tumors. The anatomic relationship between tumors and the associated fibers was analyzed.

RESULTSBy selecting appropriate regions of interest, the associated fibers in the dorsal pathways (superior longitudinal fasciculus/arcuate fasciculus, including both direct and indirect pathways) and ventral pathways (uncinate fasciculus, middle longitudinal fasciculus, inferior longitudinal fasciculus and inferiorfronto-occipital fasciculus) were reconstructed in all 18 healthy subjects. In patients with brain tumors, the relationship between the tumors and adjacent associated fibers were divided into two types: adjacent associated fibers could be displaced or separated, and involved the superior longitudinal fasciculus/arcuate fasciculus (n=6), middle longitudinal fasciculus (n=4), uncinate fasciculus (n=3), inferior longitudinal fasciculus (n=3) and inferiorfronto-occipital fasciculus (n=2); alternatively, the adjacent associated fibers were infiltrated or destroyed, and involved the inferiorfronto-occipital fasciculus (n=10), uncinate fasciculus (n=8), middle longitudinal fasciculus (n=5), inferior longitudinal fasciculus (n=4) and superior longitudinal fasciculus/arcuate fasciculus (n=3).

CONCLUSIONSThe associated fibers of language pathways could be visualized rapidly and in real-time by fiber tracking technology based on diffusion tensor imaging. This is feasible for preoperative planning regarding brain tumors adjacent to the language cortex.

BACKGROUND: Craniofacial resection (CFR) has been regarded as a standard treatment for various tumors involving the anterior skull base. The purpose of this study was to evaluate the results of CFR for the patients with anterior skull base malignancies in our hospital. METHODS: We retrospectively analyzed 17 patients with anterior skull base malignancies treated with CFR between 2001 and 2012. Mean follow-up duration was 41 months (range, 2-103 months). RESULTS: Intracranial involvement was found in 11 patients (65%) and orbital extension in 6 patients (35%). Classical bifrontal craniotomy was combined with endoscopic endonasal approach in 14 patients and external approach in 3 patients. Vascularized flap was used for reconstruction of the anterior fossa floor in 16 patients (94%). The most common pathological type was squamous cell carcinoma (6 patients). Gross total resection was achieved in all cases. Postoperative complications developed in 4 patients (24%) and included local wound problem and brain abscess. One patient with liver cirrhosis died from unexpected varix bleeding after the operation. Although postoperative treatment, such as radiotherapy or chemotherapy, was performed in 14 patients, local recurrence was seen in 6 patients. The mean overall survival time after the operation was 69.0 months (95% confidence interval: 47.5-90.5 months) with a 1-, 2-, and 5-year survival rate of 82.3%, 76.5%, and 64.7%, respectively. Postoperative radiotherapy was found to be the powerful prognostic factor for favorable survival. CONCLUSION: Considering the higher local control rate and acceptable complication or mortality rate, CFR with adjuvant radiotherapy is a gold standard treatment option for malignant tumors involving anterior skull base, especially with extensive intracranial involvement.
