Of 730 patients, 17 (1.9%) had BMs, median age 61 years (range 15-77); 8 (53%) male, unknown primary NEN site: 40%. Patients with BMs had grade 3 (G3) EP-NENs 11 (73%), G2: 3 (20%), G1: 1 (7%). Eight ...
BMs in patients with EP-NENs are rare and of increased risk in G3 vs. G1 + G2 EP-NENs. Survival outcomes are poor, and a greater understanding is needed to improve therapeutic outcomes....
Postradiation treatment necrosis is one of the most serious late sequelae and appears within 6 months. The magnetic resonance spectroscopy imaging (MRSI) has been used for the detection of brain tumor...
The research was performed in accordance with the preferred reporting items for systematic review and meta-analysis guidelines. International electronic databases including 15 English sources were inv...
Nine studies were enrolled in the meta-analysis with a total of 354 patients (203 male and 151 female) whose average age ranged from 4 to 74 years. Anbarloui et al., Elias et al., Nemattalla et al., S...
MR spectroscopy is effective in distinguishing recurrent brain tumors from necrosis. Our meta-analysis revealed that Cho/NAA, Cho/Cr, and NAA/Cr ratios were significantly better predictor of detected ...
Neurosurgeons often face this dilemma. Brain neoplasm patients undergoing neurosurgery are at a high risk of venous thrombosis. However, antithrombotic drugs may induce bleeding complications. Therefo...
Despite advances in endoscopic techniques for management of benign colonic neoplasms, a rise in rates of surgical treatment has been reported. We used a nationally representative cohort to characteriz...
All patients undergoing elective partial colectomy for benign or malignant colonic neoplasms were identified using the 2012-2019 National Inpatient Sample. Those presenting with inflammatory bowel dis...
Of 569,280 colectomy procedures included for analysis, 153,435 (27.0%) were performed for benign lesions. The proportion of Benign operations decreased from 28.6% in 2012 to 23.7% in 2019 (P for trend...
The present national study identifies a decrease in colectomy for benign polyps from 2012-2019. Future investigations should identify patients who would most benefit from surgical resection and addres...
Differentiating tumefactive demyelinating lesions (TDL) from neoplasms of the central nervous system continues to be a diagnostic dilemma in many cases....
Our study aimed to examine and contrast the clinical and radiological characteristics of TDL, high-grade gliomas (HGG) and primary CNS lymphoma (CNSL)....
This was a retrospective review of 66 patients (23 TDL, 31 HGG and 12 CNSL). Clinical and laboratory data were obtained. MRI brain at presentation were analyzed by two independent, blinded neuroradiol...
Patients with TDLs were younger and predominantly female. Sensorimotor deficits and ataxia were more common amongst TDL whereas headaches and altered mental status were associated with HGG and CNSL. C...
Careful evaluation of clinical and radiological features helps in differentiating TDLs at first presentation from CNS neoplasms....
The aim of the study was to investigate the concentration and activity of tissue factor (TF) and Tissue factor pathway inhibitor (TFPI) as well as the concentration of thrombin-antithrombin (TAT) comp...
Pediatric benign laryngeal tumors can often be treated as same-day surgeries. This study identified factors associated with prolonged hospital stay in children undergoing laryngeal surgery for benign ...
A retrospective analysis of records of pediatric patients who underwent laryngeal surgery with a post-op diagnosis of benign tumor was performed with the American College of Surgeons Pediatric Nationa...
1775 patients were identified with a mean age at time of surgery of 8.95 years (95% CI 8.76-9.14). 966 (54.4%) were males and 809 (45.6%) were females. Mean LOS was 0.22 days (95% CI 0.12-0.32). Only ...
This study suggests that laryngeal surgery for benign tumors is safe but recognizes that patients with comorbidities or young children may require a prolonged stay. Awareness of these implications may...
Preoperative anxiety is common among patients, particularly in neurosurgical patients. The aim of the study was to evaluate the incidence and predictive factors of preoperative anxiety using the state...
Sixty patients aged 18 to 65 years with American Society of Anesthesiologists physical status score I/II scheduled for elective craniotomy for a supratentorial neoplasm were recruited into this prospe...
Sixty percent of patients had preoperative anxiety (STAI-S ≥37). An APAIS score of 10 identified preoperative anxiety with a sensitivity, specificity, and positive predictive value of 97%, 96%, and 97...
Patients with supratentorial neoplasms have a high incidence of preoperative anxiety; an APAIS score of 10 is the optimal cutoff to identify anxious patients in the preoperative period. Need-for-infor...
During the V Siena Immuno-Oncology (IO) Think Tank meeting in 2021, conditions were discussed which favor immunotherapy responses in either primary or secondary brain malignancies. Core elements of th...
Gliomas are malignant tumors in the central nervous system. Cuproptosis is a newly discovered cell death mechanism targeting lipoylated tricarboxylic acid cycle proteins. Previous studies have found t...
