Two different primary tumours of the brain in a patient with breast cancer

Risk of developing glioblastoma following non-CNS primary cancer: a SEER analysis between 2000 and 2018

BACKGROUND

Patients with a prior malignancy are at elevated risk of developing subsequent primary malignancies (SPMs). However, the risk of developing subsequent primary glioblastoma (SPGBM) in patients with a prior cancer history is poorly understood.

METHODS

We used the Surveillance, Epidemiology, and End Results (SEER) database and identified patients diagnosed with non-CNS malignancy between 2000 and 2018. We calculated a modified standardized incidence ratio (M-SIR), defined as the ratio of the incidence of SPGBM among patients with initial non-CNS malignancy to the incidence of GBM in the general population, stratified by sex latency, and initial tumor location.

RESULTS

Of the 5,326,172 patients diagnosed with a primary non-CNS malignancy, 3559 patients developed SPGBM (0.07%). Among patients with SPGBM, 2312 (65.0%) were men, compared to 2,706,933 (50.8%) men in the total primary non-CNS malignancy cohort. The median age at diagnosis of SPGBM was 65 years. The mean latency between a prior non-CNS malignancy and developing a SPGBM was 67.3 months (interquartile range [IQR] 27-100). Overall, patients with a primary non-CNS malignancy had a significantly elevated M-SIR (1.13, 95% CI 1.09-1.16), with a 13% increased incidence of SPGBM when compared to the incidence of developing GBM in the age-matched general population. When stratified by non-CNS tumor location, patients diagnosed with primary melanoma, lymphoma, prostate, breast, renal, or endocrine malignancies had a higher M-SIR (M-SIR ranges: 1.09-2.15). Patients with lung cancers (M-SIR 0.82, 95% CI 0.68-0.99), or stomach cancers (M-SIR 0.47, 95% CI 0.24-0.82) demonstrated a lower M-SIR.

CONCLUSION

Patients with a history of prior non-CNS malignancy are at an overall increased risk of developing SPGBM relative to the incidence of developing GBM in the general population. However, the incidence of SPGBM after prior non-CNS malignancy varies by primary tumor location, with some non-CNS malignancies demonstrating either increased or decreased predisposition for SPGBM depending on tumor origin. These findings merit future investigation into whether these relationships represent treatment effects or a previously unknown shared predisposition for glioblastoma and non-CNS malignancy.

The Association Between Meningioma and Breast Cancer: A Systematic Review and Meta-analysis

Importance

A potential relationship between meningioma and breast cancer was suggested 70 years ago. However, to date, no conclusive evidence is available on this topic.

Objective

To provide a comprehensive review of the literature on the association of meningioma with breast cancer, supported by a meta-analysis.

Data Sources

A 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 Selection

All 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 Synthesis

Data 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 Measures

The 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.

Results

A 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 Relevance

This 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.

Glioblastoma Multiforme and Breast Cancer: Report on 11 Cases and Clinico-Pathological Remarks

The association between breast cancer and glioblastoma multiforme has not been amply analyzed in the literature. We describe 11 female patients with a diagnosis of glioblastoma multiforme who were treated when younger for breast cancer. We believe that this association is not due to chance but rather to genetic changes in hormone status and in particular to sex hormones. Another important point of view is represented by the chemotherapy treatment of breast cancer, which could have a carcinogenic effect and explain the growth of glioblastoma. This consideration, in our opinion, is important, because more effort should be made to understand the pathogenesis of glioblastoma multiforme and to improve the therapeutic approaches.

Metachronous Development of Meningothelial Meningioma, Basal Cell Carcinoma, and Glioblastoma Multiforme in a Patient with Pancreatic Incidentaloma

We report the unique case of a 61-year-old male patient with known pancreatic incidentaloma who additionally developed 3 other histologically different tumors: left sphenoid wing meningothelial meningioma, basal cell carcinoma of the occiput, and right occipital lobe glioblastoma multiforme. The latter were totally removed with a favorable clinical outcome. The patient's family history was unremarkable, and no data on any previous head and neck irradiation were found.

Outcome of patients with malignant glioma and synchronous or metachronous non-central nervous system primary neoplasms

Patients with malignant glioma who are also diagnosed with one or more primary neoplasms of other organs present a unique challenge in both determining prognosis and clinical management. The overlapping impact of the malignancies and their treatment result in confounding variables that may adversely affect optimal management of such patients. Additionally, the glioma-related characteristics and survival outcome of these patients is not well-defined. In this retrospective chart and data review from our longitudinal database, we identified patients with malignant glioma including anaplastic glioma and glioblastoma, diagnosed between January 2005 and June 2011, who were also diagnosed with other non-CNS primary neoplasms. Patients with known genetic syndromes were excluded. The data was analyzed to determine the clinical characteristics and glioma-related survival. A total of 204 patients with malignant glioma (165 glioblastoma and 39 anaplastic glioma) were identified. There was no significant difference in the overall survival or progression-free survival between patients with malignant glioma plus non-CNS primary neoplasm when compared with patients with malignant glioma only. In patients with glioblastoma and non-CNS malignancy, the duration between diagnosis of glioblastoma and non-CNS neoplasms did not significantly alter glioma-related survival. Patients with malignant glioma who were diagnosed with other non-CNS malignancy have survival outcome comparable to those with malignant glioma only. The duration between diagnosis of glioblastoma and diagnosis of non-CNS neoplasms did not affect survival. Further prospective studies specifically addressing survival and molecular characteristics of patients with malignant glioma plus non-CNS cancers are recommended.

Multicentric Glioblastoma Multiforme in a Patient with BRCA-1 Invasive Breast Cancer

Breast cancer is the most common cancer in women. Germline mutations in BRCA-1 and BRCA-2 significantly increase the risk of developing breast and ovarian cancers, and are also associated with an increased incidence of primary cancers at other sites. We report the case of a 46-year-old woman previously treated for ductal adenocarcinoma of the breast with BRCA-1 who subsequently was diagnosed with multicentric glioblastoma multiforme (GBM) in the right temporal and right occipital lobes. We briefly discuss the incidence of BRCA-1 mutations in breast cancer as well as other primary neoplasms and consider potential mechanisms shared in the pathogenesis of breast and glial tumors.

Intracranial meningioma and breast cancer

Breast carcinoma has a high predisposition to metastasize to the brain parenchyma. An association between carcinoma of the breast and intracranial meningioma has been reported. The available published articles regarding patients with intracranial meningioma and breast carcinoma have been reviewed. To the best of our knowledge, 86 cases including our 4 cases have so far been reported. All cases were female, and the mean age was 62.4 years when intracranial meningioma was diagnosed. The mean interval of the 2 tumours was 4.5 years. Twenty-five cases of breast tumour were infiltrating duct carcinomas. The location of intracranial meningioma and pathologic subtype showed no specific predominance. Hormone receptor study was performed in 28 cases. In meningioma, the positive rate of progesterone receptor (32.1%) is higher than oestrogen receptor (7.1%); while the positive rate of oestrogen receptor (53.6%) is higher than the progesterone receptor (42.9%) in breast cancer. A review of this study is presented with emphasis on the existence of intracranial meningioma and breast cancer in one patient at different periods. Lesions of the central nervous system in patients with breast cancer should not be immediately labeled as metastases. Intracranial meningioma should be excluded. Likewise, patients with meningioma should have periodic physical examinations and mammographies whereby disease may be diagnosed and treated at an early stage

Adamantinoma and meningioma occurring synchronously in a patient with breast cancer: a case report

Screening mammography of a woman with no symptoms led to the diagnosis of carcinoma of the breast, an intracranial meningioma, and adamantinoma of the right tibia. This is the first reported case of three synchronous primary tumors of different tissue origins. Biopsy is essential for diagnosing or excluding primary tumor(s) in cases of suspected metastases occurring at a limited number of sites.

Gliomatosis cerebri mimicking a metastatic breast cancer: fatal outcome

Gliomatosis cerebri (GC) is defined by the World Health Organization as a neoplasm of the glial cells. It is extremely rare, and there exists only 160 documented cases since 1897. There is no known treatment and the median survival rate is one year. The association of extracranial and CNS tumors is unusual, only three cases of breast cancer have been associated with gliomas and meningiomas but none with GC. Below we describe a case of breast cancer associated with GC and review the anatomoclinical and radiological manifestations of Gliomatosis Cerebri.

Concurrent adjacent meningioma and astrocytoma: a report of three cases and review of the literature

Three patients presenting with an adjacent meningioma and astrocytoma are described. A review of the literature discusses several modes of neuroimaging and the difficulties in diagnosing simultaneous adjacent tumors. Aspects of the pathology and etiology of these tumors are also reviewed.

Intracranial meningiomas associated with glial tumours: a review based on 54 selected literature cases from the literature and 3 additional personal cases

The simultaneous occurrence of meningioma and glioma is extremely rare. Three new cases and 54 adequately described in the literature are analyzed. Clinical diagnosis may be difficult due to discrepancy between clinical and radiological findings. Unexpected clinical deterioration following removal of a tumour and relapse simulating recurrence may occur. The introduction of CT technology does not seem to have offered the expected contribution to the early diagnosis of these coincidental lesions, at least before the introduction of the newer generation scanners or MRI. While removal of both tumours in one session yielded the best results, surgery for the sole glioma appeared to be associated with an unacceptably high mortality. Although several aetiopathogenetic hypotheses have been suggested for explaining this curious association, coincidental meningioma and glioma are most likely to be different primary brain tumours occurring randomly in the same individual.
