“…When compared with studies from western countries, we observed a comparable frequency of nerve sheath tumors as well as of the neuroepithelial tumors in our series, whereas the incidence of meningioma was low (6.3%) as compared to that reported by western authors (16-46%). [10,11,[16][17][18] However, the latter was similar to report by studies from Japan [6] to China [7] (11-15%). This compares favorably with epidemiological studies that Asian populations have a relatively less incidence of spinal meningioma than western countries.…”

Introduction and Methods:We retrospectively analyzed 111 patients with spinal tumors operated over a period of 9 years to observe the relative frequency of different lesions, their clinical profile, functional outcome and prognostic factors. 30/111 (27%) were extradural, 40/111 (36.1%) were intradural extramedullary (IDEM) and 41/111 (36.9%) were intramedullary spinal cord tumors (IMSCTs). Mean age at surgery was 30.81 years (range 1–73 years). The average preoperative duration of symptoms was 16.17 months (15 days to 15 years). Major diagnoses were ependymomas and astrocytomas in IMSCT group, schwanommas and neurofibromas in IDEM group, and metastasis, lymphoma in extradural group. The common clinical features were motor weakness in 78/111 (70.27%), sensory loss in 55/111 (49.54%), pain 46/111 (41.44%), and sphincter involvement in 47/111 (42.43%) cases.Results:Totally, 88/111 (79.27%) patients had improvement in their functional status, 17/111 (15.31%) remained same, and 6/111 (5.4%) were worse at time of their last follow-up. The mean follow-up was 15.64 months (1.5 m−10 years). Totally, 59 out of 79 patients, who were dependent initially, were ambulatory with or without the aid. Most common complication was persistent pain in 10/111 (9%) patients and nonimprovement of bladder/bowel symptoms in 7/111 (6.3%). One patient died 3 months after surgery.Conclusions:(1) Congenital malformative tumors like epidermoids/dermoids (unrelated to spina bifida) occur more frequently, whereas the incidence of spinal meningioma is less in developing countries than western populations. (2) The incidence of intramedullary tumors approaches to that of IDEM tumors. Intramedullary tumors present at a younger age in developing countries. (3) Rare histological variants like primitive neuroectodermal tumors should also be considered for histological differential diagnosis of spinal tumors. (4) Preoperative neurologic status is the most important factor related to outcome in spinal tumors.

“…English-language full text was not available for 26 records; hence, they were excluded. Finally, 53 studies were included for this systematic review: 27 case reports, 14 case series and 12 cancer registry studies . The case reports, case series, and cancer registry studies described a total of 2238 individual patients diagnosed with both pathologies, including patients with intracranial collision tumors.…”

“…When comparing the breast cancer studies, the heterogeneity test results were highly statistically significant (Cochran Q = 345.5; df = 10; P < .001), with an I 2 of 98%, indicating that the between-study heterogeneity was high. Therefore, a random-effects model was chosen for the meta-analysis.…”

The Association Between Meningioma and Breast Cancer

et al. 2023

ImportanceA potential relationship between meningioma and breast cancer was suggested 70 years ago. However, to date, no conclusive evidence is available on this topic.ObjectiveTo provide a comprehensive review of the literature on the association of meningioma with breast cancer, supported by a meta-analysis.Data SourcesA systematic PubMed search was performed up to April 2023 to identify articles on the association of meningioma with breast cancer. The following key words were used strategically: meningioma, breast cancer, breast carcinoma, association, relation.Study SelectionAll studies reporting women diagnosed with meningioma and breast cancer were identified. The search strategy was not limited by study design or publication date but only included articles in English. Additional articles were identified via citation searching. Studies reporting a complete population of meningiomas or breast cancer patients throughout a specific study period and a proportion of patients with a second pathology could be used for the meta-analysis.Data Extraction and SynthesisData extraction was performed by 2 authors in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) statement. Meta-analyses regarding both populations were performed using a random-effects model. Risk of bias was assessed.Main Outcomes and MeasuresThe main measures were whether there was an increased prevalence of breast cancer in female patients with meningioma and whether there was an increased prevalence of meningioma in female patients with breast cancer.ResultsA total of 51 retrospective studies (case reports, case series, and cancer registry reports) describing 2238 patients with both diseases were identified; 18 studies qualified for prevalence analyses and meta-analysis. The random-effects meta-analysis (13 studies) revealed a significantly greater prevalence of breast cancer in female patients with meningioma than in the overall population (odds ratio [OR], 9.87; 95% CI, 7.31-13.32). Meningioma incidence in patients with breast cancer (11 studies) was greater than that in the baseline population; however, the difference according to the random-effects model was not statistically significant (OR, 1.41; 95% CI, 0.99-2.02).Conclusions and RelevanceThis large systematic review and the meta-analysis on the association between meningioma and breast cancer found nearly 10-fold higher odds of breast cancer in female patients with meningioma compared with the general female population. These findings suggest that female patients with meningioma should be screened more intensively for breast cancer. Further research is required to identify the factors causing this association.

“…Gliomas are the most prevalent subgroup of primary brain tumors, a heterogeneous group of uncommon brain cancers with a relatively high mortality. However, there is a rare type among these tumors that are considered to have a better prognosis compared to other subtypes, due to their sensitivity to chemotherapy, known as Oligodendrogliomas ( 1 - 10 ). Recently, a correlation has been found between the response of these tumors to chemotherapy with certain genetic anomalies, including loss of 1p and 19q ( 1 , 5 , 7 , 8 , 11 ).…”

Basic Characteristics of Oligodendrogliomas: The Shohada-e Tajrish Hospital Experience (2008-2014)

et al. 2017

Background and Objectives: Gliomas are the most prevalent subgroup of primary brain tumors with a relatively high mortality. However, oligodendrogliomas have a better prognosis compared to other subtypes due to their sensitivity to chemotherapy. Considering the low incidence and the resulting lack of information about oligodendrogliomas, particularly in Iran, this study aimed at assessing their basic characteristics. Methods: In this descriptive retrospective study, patients with definite diagnosis of oligodendroglioma were identified by reviewing the archives of pathology reports at the department of pathology of Shohada-e Tajrish Hospital during years 2008 to 2014. Age, gender, location, and the grade of the tumor were extracted and entered to the SPSS statistical software for analysis. Results: A total of 182 patients, including 115 males (63.2%) and 67 females (36.8%), were included with a mean age of 38.5±13.36 years. Frontal lobe was involved in 53 patients (29.1%), parietal lobe in 31 (17.0%), temporal lobe in 22 (12.1%), frontoparietal area in 15 (8.2%), parieto-occipital area in 11 (6.0%), temporoparietal and frontotemporal areas each in 9 subjects (4.9%), occipital lobe in 5 (2.7%), and the brainstem in 4 (2.2%). Furthermore, 108 cases (59.3%) had grade-2 and the remaining74 patients (40.7%) had grade-3 anaplastic oligodendrogliomas. The mean age of subjects with brainstem oligodendrogliomas was significantly lower than the other patients (p=0.025). Conclusion: Oligodendrogliomas commonly effects the frontal lobe, followed by the parietal and temporal lobes. The mean age of subjects with brainstem lesions was significantly lower than other patients. Age, gender or location of the tumor did not independently predict a higher grade lesion.
