RESUMEN
PURPOSE: Leptomeningeal disease (LMD) is a devastating complication of metastatic breast cancer (MBC). It is critical to better understand the risk factors, natural history, and treatment outcomes, including patients in a modern cohort. METHODS: In this single center retrospective cohort study, we identified patients with MBC and LMD who received care from 2000 to 2024 and abstracted key clinical, treatment, and survival data. RESULTS: We identified 111 patients with MBC and LMD, including patients with the following subtypes: HR+/HER2- (n = 53, 47.7%), HER2+ (n = 30, 27.0%), and triple negative breast cancer (TNBC; n = 28, 25.2%). Median time from the diagnosis of MBC to LMD was 16.4 months (range 0-101.3 months). After the diagnosis of LMD, most patients received systemic therapy (n = 66, 59.5%) and/or central nervous system (CNS)-directed therapy (n = 94, 84.7%) including intrathecal therapy (n = 42, 37.8%) and/or CNS-directed radiation therapy (n = 70, 63.1%). In all patients, median overall survival (OS) from the diagnosis of LMD to death was 4.1 months (range 0.1-78.1 months) and varied by subtype, with HR+/HER2- or HER2+ MBC patients living longer than those with TNBC (4.2 and 6.8 months respectively vs. 2.0 months, p < 0.01, HR 2.15, 95% CI 1.36-3.39). Patients who received CNS-directed therapy lived longer than those who did not (4.2 vs. 1.3, p = 0.02 HR 0.54, 0.32-0.91). Patients diagnosed with LMD from 2015 to 2024 lived longer than those diagnosed from 2000 to 2014 (6.4 vs. 2.9 months, p = 0.04, HR 0.67, 95% CI 0.46-0.99). On multivariable analysis, having TNBC was associated with shorter OS from time of LMD to death (p = 0.004, HR 2.03, 95% CI 1.25-3.30). CONCLUSION: This is one of the largest case series of patients with MBC and LMD. Patients diagnosed with LMD from 2015 to 2024 lived longer than those diagnosed from 2000 to 2014, although median OS was short overall. Patients with TNBC and LMD had particularly short OS. Novel therapeutic strategies for LMD remain an area of unmet clinical need.

PURPOSE: Treatment decisions for leptomeningeal disease (LMD) rely on patient risk stratification, since clinicians lack objective prognostic tools. The introduction of rare cell capture technology for identification of cerebrospinal fluid tumor cells (CSF-TCs), such as CNSide assay, improved the sensitivity of LMD diagnosis, but prognostic value is unknown. This study assesses the prognostic value of CSF-TC density in patients with LMD from solid tumors. METHODS: We conducted a retrospective cohort study of patients with newly diagnosed or previously treated LMD from a single institution who had CNSide assay testing for CSF-TCs from 2020 to 2023. Univariable and multivariable survival analyses were conducted with Cox proportional-hazards modeling. Maximally-selected rank statistics were used to determine an optimal cutpoint for CSF-TC density and survival. RESULTS: Of 31 patients, 29 had CSF-TCs detected on CNSide. Median (interquartile range [IQR]) CSF-TC density was 67.8 (4.7-639) TCs/mL. CSF cytology was positive in 16 of 29 patients with positive CNSide (CNSide diagnostic sensitivity = 93.5%, negative predictive value = 85.7%). Median (IQR) survival from time of CSF-TC detection was 176 (89-481) days. On univariable and multivariable analysis, CSF-TC density was significantly associated with survival. An optimal cutpoint for dichotomizing survival by CSF-TC density was 19.34 TCs/mL. The time-dependent sensitivity and specificity for survival using this stratification were 76% and 67% at 6 months and 65% and 67% at 1 year, respectively. CONCLUSIONS: CSF-TC density may carry prognostic value in patients with LMD from solid tumors. Integrating CSF-TC density into LMD patient risk-stratification may help guide treatment decisions.

PURPOSE: Frailty is an independent risk factor for adverse postoperative outcomes following intracranial meningioma resection (IMR). The role of the Risk Analysis Index (RAI) in predicting postoperative outcomes following IMR is nascent but may inform preoperative patient selection and surgical planning. METHODS: IMR patients from the Nationwide Inpatient Sample were identified using diagnostic and procedural codes (2019-2020). The relationship between preoperative RAI-measured frailty and primary outcomes (non-home discharge (NHD), in-hospital mortality) and secondary outcomes (extended length of stay (eLOS), complication rates) was assessed via multivariate analyses. The discriminatory accuracy of the RAI for primary outcomes was measured in area under the receiver operating characteristic (AUROC) curve analysis. RESULTS: A total of 23,230 IMR patients (mean age = 59) were identified, with frailty statuses stratified by RAI score: 0-20 "robust" (R)(N = 10,665, 45.9%), 21-30 "normal" (N)(N = 8,895, 38.3%), 31-40 "frail" (F)(N = 2,605, 11.2%), and 41+ "very frail" (VF)(N = 1,065, 4.6%). Rates of NHD (R 11.5%, N 29.7%, F 60.8%, VF 61.5%), in-hospital mortality (R 0.5%, N 1.8%, F 3.8%, VF 7.0%), eLOS (R 13.2%, N 21.5%, F 40.9%, VF 46.0%), and complications (R 7.5%, N 11.6%, F 15.7%, VF 16.0%) significantly increased with increasing frailty thresholds (p < 0.001). The RAI demonstrated strong discrimination for NHD (C-statistic: 0.755) and in-hospital mortality (C-statistic: 0.754) in AUROC curve analysis. CONCLUSION: Increasing RAI-measured frailty is significantly associated with increased complication rates, eLOS, NHD, and in-hospital mortality following IMR. The RAI demonstrates strong discrimination for predicting NHD and in-hospital mortality following IMR, and may aid in preoperative risk stratification.

PURPOSE: The number of leptomeningeal metastasis (LM) patients has increased in recent years, as the cancer survival rates increased. An optimal prediction of prognosis is essential for selecting an appropriate treatment. The European Association of Neuro-Oncology-European Society for Medical Oncology (EANO-ESMO) guidelines for LM proposed a classification based on the cerebrospinal fluid cytological findings and contrast-enhanced magnetic resonance imaging (MRI) pattern. However, few studies have validated the utility of this classification. This study aimed to investigate the prognostic factors of LM, including the radiological and cytological types. METHODS: We retrospectively analyzed the data of 240 adult patients with suspected LM who had undergone lumbar puncture between April 2014 and September 2021. RESULTS: The most common primary cancer types were non-small-cell lung cancer (NSCLC) (143 (60%)) and breast cancer (27 (11%)). Positive cytology results and the presence of leptomeningeal lesions on contrast-enhanced MRI correlated with decreased survival in all patients. Nodular lesions detected on contrast-enhanced magnetic resonance were a poor prognostic factor in cytology-negative patients, while contrast-enhanced patterns had no prognostic significance in cytology-positive patients. Systemic therapy using cytotoxic agents and molecular-targeted therapy after LM diagnosis correlated with prolonged survival, regardless of the cytology results. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor treatment and systemic chemotherapy after LM improved the survival of EGFR-mutated and wild-type NSCLC patients with positive cytology results. CONCLUSIONS: This study validated the efficacy of prognostication according to the EANO-ESMO guidelines for LM. Systemic therapy after LM diagnosis improves the survival of NSCLC patients.

PURPOSE: To examine demographic and clinical characteristics and their association with survival in grade 2 and 3 pediatric meningiomas in a large cohort using the National Cancer Database (NCDB). METHODS: We conducted a comprehensive analysis using data from NCDB between 2004 to 2018. Tumor-specific data included tumor grade and size. Treatment details, including surgical resection, extent of resection, and radiotherapy, were gathered. Our analytic approach incorporated logistic and Poisson regression, Kaplan-Meier survival estimates, and Cox proportional hazards models. RESULTS: Among the included 239 patients aged 0-21 years, age category distribution was significantly different between grade 2 and grade 3 tumors (p = 0.018). For grade 2 meningiomas, 51.5% of patients were female, and 76.7% were white. 85.3% of patients with grade 2 meningiomas underwent surgical resection, of which 67% underwent gross total resection. Overall survival (OS) was significantly different between resected and non-resected patients (p = 0.048). Uninsured patients were over seven times as likely to have prolonged length of stay (LOS) versus those with private insurance (OR = 7.663, p = 0.014). For grade 3 meningiomas, 51.4% of patients were male, and 82.9% were white. 91.4% of patients with grade 3 meningiomas underwent surgical resection, of which 53.3% underwent subtotal resection. OS was not significantly different between resected and non-resected patients (p = 0.659). CONCLUSION: In summary, there were significant differences in age, maximum tumor dimension, unplanned readmission, radiotherapy, and treatment combinations between grade 2 and 3 meningiomas. These findings highlight the intricacies of managing pediatric meningiomas and emphasize the necessity for tailored therapeutic approaches to enhance outcomes in the future.

PURPOSE: We conducted a National Cancer Database (NCDB) study to investigate the epidemiological characteristics and identify predictors of outcomes associated with geriatric meningiomas. METHODS: The NCDB was queried for adults aged 60-89 years diagnosed between 2010 and 2017 with grade 2 and 3 meningiomas. The patients were classified into three age groups based on their age: 60-69 (hexagenarians), 70-79 (septuagenarians), and 80-89 (octogenarians). The log-rank test was utilized to compare the differences in overall survival (OS). Univariate and multivariate Cox proportional hazards regressions were used to evaluate the mortality risk associated with various patient and disease parameters. RESULTS: A total of 6585 patients were identified. Hexagenerians were the most common age group (49.8%), with the majority of meningiomas being classified as grade 2 (89.5%). The incidence of high-grade meningiomas increased in all age groups during the study period. Advanced age, male sex, black race, lower socioeconomic status, Charlson-Deyo score ≥ 2, and higher tumor grade were independent factors of poor survival. Among the modes of treatment, the extent of surgical resection, adjuvant radiotherapy, and treatment at a noncommunity cancer program were linked with better outcomes. CONCLUSION: In geriatric patients with high-grade meningiomas, the greater extent of surgical resection and radiotherapy are associated with improved survival. However, the management and outcome of geriatric patients with higher-grade meningiomas are also associated with several socioeconomic factors.

BACKGROUND/AIM: Meningeal melanocytomas are rare tumors of the central nervous system and optimal treatment needs further clarification. This study compared subtotal resection (STR), STR plus radiation therapy (RT), gross total resection (GTR), and GTR+RT to better define the role of postoperative RT. PATIENTS AND METHODS: All cases reported in the literature were reviewed. Patients (n=184) with complete data were analyzed for local control (LC) and overall survival (OS). RESULTS: On univariate analysis, GTR (vs. STR) was associated with improved LC (p=0.016). When comparing the treatment regimens, best and worst results were found after GTR+RT and STR alone, respectively (p<0.001). On univariate analysis, GTR resulted in better OS than STR (p=0.041). Moreover, the treatment regimen had a significant impact on OS (p=0.049). On multivariate analyses of LC and OS, extent of resection and treatment regimen were found to be significant factors. After STR, RT significantly improved LC but not OS. After GTR, RT did not significantly improve LC or OS. CONCLUSION: GTR was significantly superior to STR regarding LC and OS. STR+RT resulted in significantly better LC when compared to STR alone.

PURPOSE: Re-irradiation (re-RT) for recurrent intracranial meningiomas is hindered by the limited radiation tolerance of surrounding tissue and the risk of side effects. This study aimed at assessing outcomes, toxicities and prognostic factors in a cohort of patients with recurrent meningiomas re-treated with different RT modalities. MATERIALS AND METHODS: A multi-institutional database from 8 Italian centers including intracranial recurrent meningioma (RM) patients who underwent re-RT with different modalities (SRS, SRT, PT, EBRT) was collected. Biologically Equivalent Dose in 2 Gy-fractions (EQD2) and Biological Effective Dose (BED) for normal tissue and tumor were estimated for each RT course (α/ß = 2 for brain tissue and α/ß = 4 for meningioma). Primary outcome was second progression-free survival (s-PFS). Secondary outcomes were overall survival (OS) and treatment-related toxicity. Kaplan-Meier curves and Cox regression models were used for analysis. RESULTS: Between 2003 and 2021 181 patients (pts) were included. Median age at re-irradiation was 62 (range 20-89) and median Karnofsky Performance Status (KPS) was 90 (range 60-100). 78 pts were identified with WHO grade 1 disease, 65 pts had grade 2 disease and 10 pts had grade 3 disease. 28 pts who had no histologic sampling were grouped with grade 1 patients for further analysis. Seventy-five (41.4 %) patients received SRS, 63 (34.8 %) patients SRT, 31 (17.1 %) PT and 12 (6.7 %) EBRT. With a median follow-up of 4.6 years (interquartile range 1.7-6.8), 3-year s-PFS was 51.6 % and 3-year OS 72.5 %. At univariate analysis, SRT (HR 0.32, 95 % CI 0.19-0.55, p < 0.001), longer interval between the two courses of irradiation (HR 0.37, 95 % CI 0.21-0.67, p = 0.001), and higher tumor BED (HR 0.45 95 % CI 0.27-0.76, p = 0.003) were associated with longer s-PFS; in contrast, Ki67 > 5 % (HR 2.81, 95 % CI 1.48-5.34, p = 0.002) and WHO grade > 2 (HR 3.08, 95 % CI 1.80-5.28, p < 0.001) were negatively correlated with s-PFS. At multivariate analysis, SRT, time to re-RT and tumor BED maintained their statistically significant prognostic impact on s-PFS (HR 0.36, 95 % CI 0.21-0.64, p < 0.001; HR 0.38, 95 % CI 0.20-0.72, p = 0.003 and HR 0.31 95 % CI 0.13-0.76, p = 0.01, respectively). Acute and late adverse events (AEs) were reported in 38 (20.9 %) and 29 (16 %) patients. Larger tumor GTV (≥10 cc) was significantly associated with acute and late toxicity (p < 0.001 and p = 0.009, respectively). CONCLUSIONS: In patients with recurrent meningiomas, reirradiation is a feasible treatment option associated with acceptable toxicity profile. Prognostic factors in the decision-making process have been identified and should be incorporated in daily practice.

BACKGROUND: Leptomeningeal metastasis (LM) is a severe lung cancer complication, with potentially fatal consequences. The use of intrathecal therapy (IT) combined with systemic therapy has shown promise as a treatment approach for LM. Thus, this study aimed to evaluate the features and responses to IT combined therapy and identify determinants affecting patients with leptomeningeal metastasis resulting from lung adenocarcinoma (LM-LA). METHODS: A retrospective analysis of medical records from our hospital database was performed, covering from April 2018 to August 2022, for 37 patients diagnosed with LM-LA and treated with IT combined therapy. Patients who received IT combined therapy for LM-LA were evaluated for demographic characteristics, treatment efficacy, survival, and variables that impacted them. RESULTS: The median overall survival (mOS) of 37 patients was 16.0 months, and the survival rates at 6 and 12 months were 75.7% and 35.1%, respectively. Among the 21 patients with LM-LA who received IT combined with tyrosine kinase inhibitors (TKIs), the mOS was 17.0 months, which was significantly longer than that of patients treated with IT combined with chemotherapy (7.0 months, P = 0.010) and the best supportive care (6.0 months, P = 0.001). However, no significant survival benefit was observed in patients treated with IT combined with TKIs when compared with those treated with IT combined with PD-1 (5.0 months, P = 0.249). Multivariate analysis indicated that the combination of TKIs was an independent favorable prognostic factor for patients with LM-LA. CONCLUSION: Combination treatment is regarded as an additional option for patients with LM-LA. Compared with other combination therapies in our study, IT combined with TKI therapy provided a better survival outcome for patients with LM-LA.

BACKGROUND: Giant meningiomas may show special features in terms of biological behavior and management. We aimed to research recurrence and mortality of giant meningiomas. METHODS: Medical files of patients with meningioma with at least 1 dimension of ≥5 cm in any plane in radiological investigations between December 2012 and January 2022 were retrospectively reviewed. Tumor dimensions were measured on magnetic resonance images except 1. All patients except two underwent clinical follow-up at a mean of 27.19 ± 29.87 (range, 4-112) months. RESULTS: There were 42 patients, 26 (61.9%) women and 16 (38.1%) men who ranged in age from 31 to 85 (mean, 60.31 ± 14.86) years. Headache (57.1%) was the most common symptom. The mean tumor size was 70.14 ± 19.03 (range, 50-152) mm. Tumors were most located at the frontal convexity (40.5%). Simpson grade I resection was achieved in 19% of the cases. The tumors were World Health Organization grade 1 in 74% and grade 2 in 26% of the cases. Major complications developed in 26.1% of the patients. Recurrence happened in 5 (11.9%) cases. The number of World Health Organization grade 2 tumors (P = 0.013; P < 0.05) and tumor size (P = 0.006; P < 0.01) were significantly higher in the recurrent cases. Mortality was % 11.9 and statistically significantly higher in the recurrence group (P = 0.025; P < 0.05). CONCLUSIONS: Giant intracranial meningiomas are challenging because of surgical experience, tumor size, peritumoral edema, blood supply, anatomical changes, and limited visibility. They have a high risk of recurrence and mortality.

OBJECTIVES: To find predictive biomarkers for recurrence and progression of meningioma. BACKGROUND: Despite great advances in meningioma treatment, the prognosis remained unfavorable due to the high recurrence rate. METHODS: In this study, we evaluated the immunohistochemical expression of FOXM1, MMP-9, and Ki67 in 50 cases of intracranial meningioma to detect its potential role in meningioma progression, recurrence, and patients' survival. RESULTS: Strong FOXM1 expression was detected in 20% of the cases and was significantly associated with meningioma grade ( P = 0.002) and peritumoral brain edema (PTBE; P <0.001). Strong MMP-9 expression was noted in 32% of the cases and was significantly associated with meningioma grade and PTBE ( P <0.001, P <0.001, respectively). High Ki67 was noted in 50% and significantly associated with tumor grade and PTBE ( P <0.001, P = 0.002, respectively). The follow-up period revealed that meningiomas with strong FOXM1, strong MMP-9, and high Ki67 expression were associated with tumor recurrence, shorter OS, and recurrence-free survival. Furthermore, up-regulation of FOXM1 and MMP-9 expression had a significant relation with poor clinical response to the therapy ( P = 0.010, P = 0. 001, respectively). However, high Ki67 cases were more sensitive to clinical therapy ( P = 0.005). CONCLUSION: Strong FOXM1, strong MMP-9, and high Ki67 in meningiomas indicate highly aggressive tumors with a shortened survival rate, dismal outcome, and high risk of recurrence after the standard protocol of therapy.

BACKGROUND: Meningiomas are the most frequent primary intracranial tumor. While histological grade and grade of excision are established predictors of recurrence, the predictive ability of other clinical features, such as the role of radical excision of dural attachment and postoperative radiation therapy in intermediate-risk groups, remains unknown. METHODS: Clinical and radiological features and surgical details were analyzed in 451 World Health Organization (WHO) grade 1 intracranial meningiomas and 248 WHO grade 2 meningiomas operated on between 2010 and 2015. Outcomes were assessed in 352 WHO grade 1 and 208 WHO grade 2 meningiomas, studying the effect of extent of resection and use of radiation therapy. Kaplan-Meier analysis was used to determine differences in survival by extent of resection and use of postoperative radiation therapy in the treatment of the meningiomas. RESULTS: The mean age of the cohort was 46.3 years, with a female predominance. On univariate analysis, sex, WHO grade, and Simpson grade were significant predictors of recurrence. On multivariate analysis, WHO grade and Simpson grade remained significant predictors of recurrence. Recurrence was significantly associated with poor performance status and mortality. Postoperative radiation significantly improved progression-free survival among patients with grade 2 meningiomas who underwent gross total resection, but not among patients with grade 1 and grade 2 meningiomas who underwent subtotal resection. CONCLUSIONS: WHO grade and Simpson grade are independent predictors of recurrence in meningiomas. Regardless of WHO grade, gross total resection must be performed when possible, and postoperative radiation therapy may be recommended in grade 2 meningiomas.

OBJECTIVE: To analyze the factors associated with EGFR-mutated lung cancer with leptomeningeal metastasis (LM) in the real world that affects the prognosis of patients. MATERIALS AND METHODS: The clinical data of 123 patients with advanced EGFR mutated lung cancer combined with LM treated at Henan Cancer Hospital and confirmed by histology between January 2016 and December 2020 were retrospectively collected, and all patients were followed up until September 2021. Analyze the median overall survival (mOS) time of patients with clinical characteristics and treatment factors to explore the factors influencing the prognosis of lung cancer patients with LM. RESULTS: A total of 123 patients with EGFR-mutated lung cancer and LM were included in this study. Overall, patients with exon 19 deletion (19del) in the classical mutation of the EGFR gene had a prolonged mOS compared to patients with exon 21 L858R mutation (21L858R) (30.1 months vs. 26.0 months); patients with primary LM (mOS 21.2 months) had a significantly shorter mOS than those with secondary LM (mOS 28.3 months); mOS was also significantly shorter in patients with combined brain metastases (mOS of 25.4 months) than in patients without combined brain metastases (mOS of 33.4 months); Patients treated with tyrosine kinase inhibitors (TKI) combined with antiangiogenic therapy (bevacizumab) experienced delayed onset of LM (mOS1: 19.4 months vs. 13.9 months), and prolonged survival after LM compared with those treated with EGFR-TKI alone (mOS2: 14.5 months vs. 10.0 months); There is no survival benefit to the patients treated with EGFR-TKI combined with chemotherapy compared to the patients treated with EGFR-TKI alone. CONCLUSION: Among NSCLC-LM patients with EGFR mutation, receiving EGFR-TKI combined with antiangiogenic therapy may result in a better survival benefit. The factors of primary LM, combined brain metastasis may be prognostic factors for poor OS.

Meningioma is the most common primary brain tumor and many studies have evaluated numerous biomarkers for their prognostic value, often with inconsistent results. Currently, no reliable biomarkers are available to predict the survival, recurrence, and progression of meningioma patients in clinical practice. This study aims to evaluate the prognostic value of immunohistochemistry-based (IHC) biomarkers of meningioma patients. A systematic literature search was conducted up to November 2023 on PubMed, CENTRAL, CINAHL Plus, and Scopus databases. Two authors independently reviewed the identified relevant studies, extracted data, and assessed the risk of bias of the studies included. Meta-analyses were performed with the hazard ratio (HR) and 95% confidence interval (CI) of overall survival (OS), recurrence-free survival (RFS), and progression-free survival (PFS). The risk of bias in the included studies was evaluated using the Quality in Prognosis Studies (QUIPS) tool. A total of 100 studies with 16,745 patients were included in this review. As the promising markers to predict OS of meningioma patients, Ki-67/MIB-1 (HR = 1.03, 95%CI 1.02 to 1.05) was identified to associate with poor prognosis of the patients. Overexpression of cyclin A (HR = 4.91, 95%CI 1.38 to 17.44), topoisomerase II α (TOP2A) (HR = 4.90, 95%CI 2.96 to 8.12), p53 (HR = 2.40, 95%CI 1.73 to 3.34), vascular endothelial growth factor (VEGF) (HR = 1.61, 95%CI 1.36 to 1.90), and Ki-67 (HR = 1.33, 95%CI 1.21 to 1.46), were identified also as unfavorable prognostic biomarkers for poor RFS of meningioma patients. Conversely, positive progesterone receptor (PR) and p21 staining were associated with longer RFS and are considered biomarkers of favorable prognosis of meningioma patients (HR = 0.60, 95% CI 0.41 to 0.88 and HR = 1.89, 95%CI 1.11 to 3.20). Additionally, high expression of Ki-67 was identified as a prognosis biomarker for poor PFS of meningioma patients (HR = 1.02, 95%CI 1.00 to 1.04). Although only in single studies, KPNA2, CDK6, Cox-2, MCM7 and PCNA are proposed as additional markers with high expression that are related with poor prognosis of meningioma patients. In conclusion, the results of the meta-analysis demonstrated that PR, cyclin A, TOP2A, p21, p53, VEGF and Ki-67 are either positively or negatively associated with survival of meningioma patients and might be useful biomarkers to assess the prognosis.

ABSTRACT Objective To describe a unique operative strategy, instead the classical pterional approach, and to analyses it safety and effectiveness for removal of anterior cranial fossa meningiomas. Method We identify 38 patients with tuberculum sellae and olphactory groove meningiomas operated between 1986 and 2013. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed and analyzed retrospectively. The pterional craniotomy is extended toward the frontal bone providing access through the subfrontal route, besides the usual anterolateral view provided by the classical pterional approach. Results Surgical mortality occurred in one patient (2.6%). Gross total resection was achieved in 27 patients (86.8%). Median time of follow-up was 69.4 months. Conclusion The extended pterional approach allows excellent results. Total removal of meningiomas of the anterior cranial fossa was obtained in 86.8 % of patients, with low morbidity and mortality.
RESUMO Objetivo Descrever a craniotomia pterional estendida, ao invés da abordagem pterional clássica, e analisar sua segurança e eficácia para a remoção dos meningiomas da fossa anterior. Método Identificamos 38 pacientes com meningiomas do tubérculo da sela e da goteira olfatória operados entre 1986 e 2013. Os prontuários, relatórios cirúrgicos, exames de imagem e acompanhamento pós-operatório foram analisados retrospectivamente. A craniotomia pterional com extensão para o osso frontal permite acesso pela via subfrontal além da via anterolateral do acesso pterional clássico. Resultados A mortalidade cirúrgica foi de 2,6% (um paciente). A remoção total foi alcançada em 86,8% (27 pacientes) com um tempo médio de seguimento de 69,4 meses. Conclusão A abordagem pterional estendida permite excelentes resultados. A remoção total dos meningiomas da fossa craniana anterior foi obtida em 86,8% dos pacientes, com baixa morbi-mortalidade.

Atypical/anaplastic (World Health Organization (WHO) grades II and III) are less common and have poorer outcomes than benign meningiomas. This study aimed to analyze the outcome of patients with these tumors.Method Overall/recurrence-free survivals (RFS) and the Karnofsky Performance Scale of 52 patients with grades II (42) and III (9) meningiomas surgically treated were analyzed (uni/multivariate analysis).Results Total/subtotal resections were 60.8%/35.3%. Patients <60 years-old and grade II tumors had longer survival. Grade II tumors, total resection andde novo meningioma had better RFS (univariate analysis). Patients >60 years-old, de novo meningioma and radiotherapy had longer survival and patients <60 years-old and with grade II tumors had longer RFS (multivariate analysis). Recurrence rate was 51% (39.2% Grade II and 66.7% Grade III). Operative mortality was 1.9%.Conclusion Age <60 years-old, grade II tumors and de novomeningiomas were the main predictors for better prognosis among patients with grades II and III meningiomas.

The purpose of this study was to evaluate treatment patterns, outcome and prognosticators for patients with leptomeningeal metastases from solid tumor. Medical records of 80 patients from January 1, 2004 to May 31, 2011 were retrospectively reviewed. Most frequent site of origin was the lung (59%) followed by the breast (25%). Most patients were treated with intrathecal chemotherapy (90%) and/or whole brain radiotherapy (67.5%). Systemic therapy was offered to 27 patients (33.8%). Percentage of patients treated with single, dual, and triple modality were 32.5%, 43.8%, and 23.8%, respectively. Median survival was 2.7 months and 1 yr survival rate was 11.3%. Multivariate analysis showed that negative cerebrospinal fluid cytology, fewer chemotherapy regimen prior to leptomeningeal metastases, whole brain radiotherapy, systemic therapy, and combined modality treatment (median survival; single 1.4 vs. dual 2.8 vs. triple 8.3 months, P<0.001) had statistical significance on survival. Subgroup analysis of non-small cell lung cancer (NSCLC) patients showed that targeted therapy had significant independent impact on survival (median survival; 10.5 vs. 3.0 months, P=0.008). Unlike previous reports, survival of patients with NSCLC primary was comparable to breast primary. Furthermore, combined modality treatment for all patients and additionally targeted therapy for NSCLC patients should be considered in the treatment of leptomeningeal metastases from solid tumor.

Spinal cord tumors are a rare neoplasm of the central nervous system (CNS). The occurrence of metastases is related to poor prognosis. The authors analyzed one series of metastasis cases and their associated mortality. METHODS: Clinical characteristics were studied in six patients with intramedullary tumors with metastases in a series of 71 surgical cases. RESULTS: Five patients had ependymomas of which two were WHO grade III. The patient with astrocytoma had a grade II histopathological classification. Two patients required shunts for hydrocephalus. The survival curve showed a higher mortality than the general group of patients with no metastases in the CNS (p<0.0001). CONCLUSION: Mortality is elevated in patients with metastasis and greater than in patients with only primary lesions. The ependymomas, regardless of their degree of anaplasia, are more likely to cause metastasis than spinal cord astrocytomas.
Tumores da medula espinhal são neoplasias raras do sistema nervoso central (SNC). A ocorrência de metástases é relacionada a pior prognóstico. Os autores analisaram uma série de casos de metástases e a mortalidade relacionada. MÉTODO: Foram estudadas as características clínicas em seis pacientes com metástases tumorais numa série de 71 casos operados. RESULTADOS: Cinco pacientes tinham ependimomas e dois dos quais foram grau III pela classificação da OMS. O paciente portador de astrocitoma tinha classificação histopatológica de grau II. Dois pacientes necessitaram de derivação devido à hidrocefalia. A curva de sobrevivência mostrou mortalidade mais elevada no grupo de pacientes com disseminação pelo SNC (p<0,0001). CONCLUSÃO: A mortalidade, além de elevada em pacientes com metástases, é maior do que em pacientes apenas com lesão primária. Os ependimomas, independentemente do seu grau de anaplasia, costumam causar mais metástases do que os astrocitomas medulares.

BACKGROUND: Olfactory groove meningiomas comprise 4-10 percent of the intracranial meningiomas. Generally they give signs of brain compression due to great size they reach before diagnosis. In this study, the clinical outcome of patients with olfactory groove meningiomas surgically treated was analyzed. METHOD: 17 patients operated on from 1988-2006. Female: 16, Male: 1. Age: 19-76 years-old (mean=53.12± 13.11). Follow-up: 1-209 months (mean=51.07±12.73. Bifrontal/bifrontal-bi-orbital approaches were used. Outcome was analyzed using survival/recurrence-free Kaplan-Mayer curves. RESULTS:16 had WHO grade 1; one grade 2 meningiomas. Resection Simpson's grade 1 was in achieved in 64.7 percent, grade 2 in 29.4 percent and grade 3 in 5.9 percent. There was no recurrence during the follow-up. Global and operative mortality were 11.8 percent. Main postoperative complications were osteomielitis (11.8 percent) and pneumonia (5.9 percent). CONCLUSION: Extensive approaches allowed total resection of most olfactory groove meningiomas with no recurrence during the follow-up, but operative mortality and local complications were high.
INTRODUÇÃO: Os meningiomas da goteira olfatória constituem 4-10 por cento dos meningiomas intracranianos. Geralmente eles causam sinais de compressão do tronco cerebral porque atingem grandes tamanhos antes do diagnóstico. Neste estudo foram analisadas os resultados do tratamento cirúrgico de pacientes com meningiomas da goteira olfatória. MÉTODO: 17 pacientes operados de 1988-2006. Mulheres: 16. Homens: 1. Idade: 19-76 anos (média=53,12±13,11). Seguimento: 1-209 meses (média=51,07±12,73. Foram utilizados acessos bifrontal/bifrontal bi-orbital. A evolução clinica foi analisada usando curvas de sobrevida e de sobrevida livre de doença de Kaplan-Mayer. RESULTADOS: 16 pacientes tinham meningioma WHO grau 1; um tinha meningioma grau 2. Ressecção Simpson grau 1 foi obtida em 64.7 por cento, grau 2 em 29.4 por cento e grau 3 em 5.9 por cento. Não houve recidiva durante o seguimento. A mortalidade global e a pós-operatória foram 11.8 por cento. As principais complicações pós-operatórias foram osteomielite (11.8 por cento) e pneumonia (5.9 por cento). CONCLUSÃO: Abordagens extensas possibilitaram ressecção total da maioria dos meningiomas da goteira olfatória sem recidiva durante o seguimento, mas a mortalidade operatória e as complicações locais foram altas.
