The objective of the work was an accentuation of clinical appearances of pathogenesis of congestive optic disc as a basis for improving their diagnosis. Material and methods. This work based on the analysis of ophthalmological symptoms in 169 patients with brain tumors that underwent neurosurgical tumor surgery at Neurosurgical Clinic of National Hospital (Ministry of Health of the Kyrgyz Republic) from 2014 to 2019. Patient’s age varied from 14 years to 67 years old, medium age was 34 years. The number of male was 63, and the number of female was 106. All patients were examined by using neurological investigation, MRI of the brain before surgery and MRI/CT after surgery. Benign tumors have been identified in 56 patients and malignant tumors in 50 patients. Glial brain tumors identified in most cases (49 patients). Results. We could investigate visual function of 55 (93 %) patients out of 169 patients with congestive optic disc caused by large appearances in the brain. 46 (27.4 %) of patients out of 169 had reduced visual acuity caused by congestive optic disc. Meanwhile 22 (13.1 %) patients had acuity in both eyes by 1.0; 6 (3.3 %) patients had a blind or a partially blind eye, whereas the reduction of visual acuity was in another eye; additionally 7 (4 %) patients were blind or nearly blind in both eyes. Conclusion. The frequency and severity of visual disorders in congestive optic disc depend on the congestive optic disc stages. The stage of severe congestive optic disc and other already existing visual disorders are prognostically unfavorable for visual functions of patients with congestive optic disc. The terms of congestive optic disc regression depend on the methods of treatment. Congestive optic disc regression is occurring slowly (from 1 month to 3 years) when the medicamental therapy is used for patients with benign intracranial hypertension. Surgical or bypass removal of the large appearance of liquor system of congestive optic disc regression is much faster (1 to 1.5 months).

Resistance To Chemotherapy

Today, there are conflicting data on the content of cancer stem cells responsible for recurrence and resistance to chemotherapy in tumors of human brain. The aim of the study was to analyze the content of CD133+ cells in different brain tumors by immunofluorescence assay and immunohistochemical method. Materials and Methods: The samples of different brain tumors removed during neurosurgical operations were studied for CD133 expression. Results: Immunofluorescence assay of tumor imprints revealed CD133+ cells in 40–85% of tumors regardless of histological type. In malignant tumors, the count of CD133+ cells was higher than in benign tumors. Immunohistochemical method used for detection of CD133+ cells was less sensitive than immunofluorescence technique. The number of CD133+ cells may vary even in tumors of the same histological type. In 20–30% of malignant tumors (glioblastomas, medulloblastomas), the content of CD133+ cells was very low or not detected at all. Conclusions: In tumors of the brain of different genesis and degree of anaplasia CD133+ cells are found out. In malignant tumors (glioblastomas and medulloblastomas), CD133+ cells are much more frequently detected than in benign brain tumors. The content of CD133+ cells in brain tumors is highly variable being small and some malignant tumors, indicating low predictive and diagnostic value of cancer stem cell content in clinical practice.

e14000 Background: The purpose of the study was to analyze changes in the total activity of trypsin-like proteinases (TLPs) in the blood plasma in patients with brain tumors for the preoperative differential diagnosis of benign, primary and secondary malignant brain tumors. Methods: TLPs were measured in 164 patients with brain tumors. The blood had been collected from the patients in a standard plastic tube with 3.8% sodium citrate (9:1) 3 days prior to the surgery. Citrate blood was centrifuged; citrated plasma was obtained and used to determine the total TLP activity by the unified kinetic method. Results were compared with the data in donors. Results: TLP activity in 37 (22.6%) of 164 patients was within the normal range (258–402 IU/mL, on the average 333.0±27.1 IU/mL). Benign brain tumors (meningioma) were diagnosed in all 37 patients after the tumor removal and histological analysis. In 74 (45.1%) of 164 patients, TLP activity was within 1158–1626 IU/mL (on the average 1331.0±102.4 IU/mL, p < 0.05), i.e. 3.8-5.3 times higher than the norm in donors (malignancy coefficient on average 4.4±0.3 times). Primary malignant brain tumors (glioblastoma) were diagnosed in all 74 patients after the tumor removal and histological analysis. In 53 (32.3%) of 164 patients, TLP activity was within 1794–2868 IU/mL (on the average 2227.0±174.1 IU/mL, p < 0.05), i.e. 5.9-9.4 times higher than the norm in donors (malignancy coefficient on average 7.3±0.5 times). Secondary malignant brain tumors (metastases) were diagnosed in all 53 patients after the tumor removal and histological analysis. Conclusions: The specificity of the proposed method for the differential diagnosis of brain tumors was very high: for benign tumors - 97.2%, for primary malignant tumors - 98.6% and for secondary malignant tumors - 98.1%. So, TLP activity indices in the blood plasma are an informative auxiliary laboratory test that will help in clarifying and/or confirming the differential diagnosis of brain tumors.

✓ Fourteen children aged 1 week to 16 years, with a variety of large or superficial brain tumors, underwent localized in vivo 31P magnetic resonance spectroscopy of their tumor. Quantitative spectral analysis was performed by measuring the area under individual peaks using a computer algorithm. In eight patients with histologically benign tumors the spectra were considered to be qualitatively indistinguishable from normal brain. The phosphocreatine/inorganic phosphate ratio (PCr/Pi) averaged 2.0. Five patients had histologically malignant tumors; qualitatively, four of these were considered to have abnormal spectra, showing a decrease in the PCr peak. The PCr/Pi ratio for this group averaged 0.85, which was significantly lower than that seen in the benign tumor group (p < 0.05). No difference between the two groups was seen in adenosine triphosphate or phosphomonoesters. It is concluded that a specific metabolic “fingerprint” for childhood brain tumors may not exist, but that some malignant tumors show a pattern suggestive of ischemia.

Associated Functions

Brain tumors occur when abnormal cells form within the brain.There are two main types of tumors: malignant and benign tumors. Then, tumors can be divided into primary that start within the brain, and secondary tumors that have spread from somewhere else, known as brain metastasis tumors. Secondary brain tumors occur in approximately 15 % of cancer patients with about half of metastases coming from lung cancer. Primary brain tumors occur in around 250,000 people a year globally, making up less than 2% of whole body tumors. According to American Brain Tumor Association the most common types of primary tumors are gliomas, representing 74,6 % of all malignant tumors and meningiomas ( 36,6% ) while more affected region is frontal lobe, about 22 % . Particularly, prefrontal cortex ( PFC ), the anterior part of the frontal lobe that is highly developed in humans plays a role in the regulation of personality, emotional, and behavioral functioning, leading to serious cognitive impairments 1. These are the psychological signs of frontal lobe tumors, in addition to other functions such as the expressive language of Broca's area or those relating to voluntary movement, linked to frontal cortical motor areas. It relates to the so-called higher nervous functions, concerning the life of relationship and communication. The PFC physiology explains the psychological mechanisms of its associated functions: connections with the limbic cortex, thalamus, hypothalamus, basal ganglia and other subcortical areas.The regions of the PFC at the base of the psychophysiological mechanisms involved are basically the dorso-lateral, the ventro-medial, the orbito-frontal establishing contacts primarily with limbic structures, such as the cingulate gyrus, hippocampus, amygdala.

In order to investigate the effectiveness and accuracy of magnetic resonance imaging (MRI) in the diagnosis of benign and malignant thoracic tumors, the research retrospectively selected 80 patients with thoracic tumors admitted from May 2019 to May 2020 as the study subject and all patients were underwent MRI detection. Using pathological diagnostic results as the gold standard, the research analyzed the detection of benign and malignant thoracic tumors by MRI, as well as the diagnostic sensitivity and specificity. After pathological diagnosis, there were 35 malignant tumors and 45 benign tumors. 41 cases of malignant tumors and 39 cases of benign tumors were diagnosed by MRI, with a diagnostic sensitivity of 80.00%, a diagnostic specificity of 71.11%, and a diagnostic compliance rate of 75.00%. In the MRI diagnosis of tumors in different parts of the chest, the diagnostic sensitivity for lung tumors, mediastinal tumors, chest wall tumors, and esophageal tumors was 83.33%, 71.43%, 83.33%, 75.00%, and 87.50%, respectively, and the specificity was 66.67%, 77.78%, 57.14%, 50.00%, and 91.67% according to and breast tumors, respectively. And the accuracy was 73.33%, 75.00%, 69.23, 62.50%, and 90.00%, respectively, with the highest diagnostic sensitivity, specificity, and accuracy for breast tumors. MRI has a good effect on the diagnosis of benign and malignant thoracic tumors and has a high diagnostic value, which is helpful to identify the location, nature, source, and lesion scope of the tumor. It is safe and worthy of promotion.

Brain tumors are caused by the growth of abnormal cells inside the Brain. Brain tumor can be classified as Benign (non cancerous) and malignant(cancerous). Malignant brain tumors usually grow rapidly when compared to benign tumors, and aggressively spread and affect the surrounding tissues. Detection of tumor in brain can turn out to be cumbersome, owing to the complex organization of the Brain. The cost of making an error in Identifying a Malignant Tumor from a Benign Tumor is too high. At a time, when cases of Brain Tumors are growing, mostly among people of age between 65 and 79, but not just confined to that age bracket, we can take advantage of the advancement in the field of technology and accurately identify tumors and help save lives.

Abstract Objective Brain tumors have become the most common solid tumors in children. The epidemiology is poorly described in China. This retrospective study aimed to describe the epidemiologic characteristics, clinical presentation, and prognosis in national health center for children. Method From January 2015 to December 2020, 484 cases age 0-18 years old diagnosed with brain tumors and receiving neurosurgery treatment were enrolled into the database. Pathology was based on the World Health Organization 2012 nervous system tumor classification, and tumor behavior were classified on International Classification of Diseases for Oncology, third edition. A descriptive and comparative statistic was performed on clinical manifestation, symptom duration, sex, age, tumor location, tumor behavior, and survival time. Results Among the 484 brain tumors, the median age at diagnosis was 4.62 [2.19, 8.17] years old (4.07 [1.64, 7.13] for benign tumors and 5.36 [2.78, 8.84] for malignant tumors). The overall male to female ratios were 1.33:1, with 1.09:1 and 1.62:1 for benign and malignant tumors respectively. Nausea and vomiting, headache were the most frequent initial symptoms. The median symptoms duration was 4[2, 21] weeks. The three most frequent tumor type were embryonal tumors (22.45%), other astrocytic tumors (20.17%), and diffuse astrocytic tumors (11.02%). Supratentorial tumors comprise 57.38% of all brain tumors. And the most common tumor locations were cerebellum and forth ventricles (38.67%), sellar region (22.87%) and ventricles (10.60%). Male were more common among choroid plexus tumors (63.64%), embryonal tumors (61.11%), ependymal tumors (68.57%), and germ cell tumors (78.13%). Patients were followed for 1 to 82 months. The overall 5-year survival was 77.4%, with 90.0% for benign tumor and 65.3% for malignant tumors. log-rank test found significant different at p <0.001 level. Conclusion Brain tumors presented particularly sexual, age dependent, and regional dependent epidemiological characteristic. Our results were consistent with previous reports, and might reflect the real epidemiology status in China.

e13543 Background: Activation of trypsin-type proteinases in cancer is a proven fact. Activity of enzymes synthesized and secreted by a malignant tumor is generally not controlled by endogenous inhibitors. Benign tumors do not come into metabolic conflict with the carrier body, at least prior to their possible malignant transformation. The purpose of the study was to analyze changes in activity of trypsin proteinases (ATP) in the blood plasma of patients to determine possible application of the parameter as an additional test in the differential diagnosis of brain tumors. Methods: The blood plasma of 164 patients was studied: 37 benign brain tumors, 74 primary glioblastomas (G) and 53 brain metastases (MTS) from breast cancer. ATP was determined before treatment using the U-2900 UV Solutions double-beam spectrophotometer (USA). The results were compared to the values in 39 healthy donors (N). The data were processed using the Statistica 10 program. Results: ATP did not differ from N in 37 of 164 patients (22.6%). After removal of the brain tumors, histological examination of surgical material showed benign brain tumors in all 37 cases. ATP in 74 of 164 patients (45.1%) exceeded N by 3.8-5.3 times (on average 4.4±0.3). Histological examination after removal of the brain tumors showed primary G in all 74 cases. ATP was 5.9-9.4 times higher than N (on average 7.3±0.5) in 53 of 164 patients (32.3%). Histological examination after removal of the brain tumors showed MTS in all 53 cases. Conclusions: ATP value similar to N indicates a benign tumor. ATP increase by 3.8-5.3 times shows the presence of a primary malignant tumor. ATP increase by 5.9-9.4 times supposes MTS.

Abstract INTRODUCTION The frequency of intraorbital tumors is small as 0.9% of all brain tumors, but its pathological type is diverse. Among them, the diagnosis of whether particularly malignant tumor scan clinically, is extremely important. Nuclear medical testing is essential for non-invasive differential diagnosis in brain tumors. SPECT, good malignancy differentiation, evaluation of malignancy, usefulness such as differentiation of non-tumorous lesions have been reported many. However, there are few reports that SPECT was useful in preoperative differential diagnosis of orbital tumors. Since 123IMP-SPECT was useful in preoperative differential diagnosis of intraorbital tumors, we report some literature considerations. METHOD Among the 27 cases of intraorbital tumors that were operated on in our clinic between August 2005 and August 2016, 14 cases of SPECT prior to surgery were examined for the usefulness of preoperative differential diagnosis. Breakdown of cases, as the malignant tumor, two cases of malignant lymphoma, MALT lymphoma 2 cases, adenoid cystic carcinoma 1 case, in one case plasma cytoma, as a benign tumor, false tumors 4 cases, three hemangioma cases, neurocytoma 1 case it was. RESULTS In IMP early image, accumulation of clear IMP was observed in all six cases of malignant tumors. In benign tumors, there is no accumulation in hemangioma and neurosheath, there is a strong accumulation in one of the four cases in false tumors, it was observed mild accumulation in the remaining two cases. Tumor to normal ratio of IMP early image was an average of 2.39 in six malignant tumors and 1.52 in 8 benign tumors. CONCLUSION This time, we examined the usefulness of 123IMP-SPECT in preoperative differential diagnosis of intraorbital tumors. The T/N ratio of intraorbital malignant tumors is higher than benign tumors, and it was thought to help to evaluate preoperative malignancy of intraorbital tumors.

AbstractThere are only a few reports examining the impact of oxidative stress in patients with benign and malignant brain tumors. In this study we investigated whether there are changes in antioxidant system (AOS) parameters and key trace elements between control, benign and malignant brain tissues. The study also aimed to examine correlations between the analyzed parameters. The study enrolled both types of brain tumors, benign tumors (BT) and malignant tumors (MT). The results were compared with control tissue (CT) without tumor infiltration collected from patients with BT. The following antioxidant parameters were determined: activities of total, manganese-containing, and copper/zinc-containing superoxide dismutase (TotSOD, MnSOD and CuZnSOD), activities of catalase, glutathione peroxidase, glutathione S-transferase, glutathione reductase and acetylcholine esterase (AChE), the concentrations of glutathione and sulfhydryl groups and of manganese (Mn), copper (Cu), zinc (Zn), and selenium (Se). BT and MT had altered activities/levels of multiple AOS parameters as compared to CT, indicating that tumor cells had an altered cell metabolism and changes in AOS represent adaptive response to increased oxidative stress. Low MnSOD and AChE and high GST activities were significant for distinguishing between MT and CT. Malignant tissue was also characterized by lower Mn and Cu concentrations relative to CT and BT. Principal Component Analysis clearly discriminated BT from CT and MT (PC1, 66.97%), while PC2 clearly discriminated CT from BT and MT (33.03%). Most correlative relationships were associated with Se in the BT group and Cu in the MT group. The results of this study reveal differences between the AOS parameters and the essential trace elements between the analyzed groups. The observed dysregulations show that oxidative stress could have an important role in disrupting brain homeostasis and its presence in the pathogenesis of benign and malignant brain tumors.
