Leptomeningeal Metastases - Epidemiology Forecast - 2034
Description
Key Highlights
Leptomeningeal metastases, also known as leptomeningeal carcinomatosis or neoplastic meningitis or carcinomatous meningitis or leptomeningeal disease, represent a serious and often debilitating complication of advanced metastatic solid tumors.
Leptomeningeal metastases, frequently seen in breast, lung, or melanoma cancers, cause CSF buildup and increased brain pressure, leading to headaches, balance issues, and cranial nerve-related weakness, numbness, or pain.
In 2024, the incident cases of leptomeningeal metastases were approximately 300,000 in the 7MM, reflecting a significant clinical burden.
As per DelveInsight analysis, the US showed the highest number of incident cases of leptomeningeal metastases, accounting for approximately 40% of the incident cases in the 7MM in 2024.
DelveInsight’s “Leptomeningeal Metastases – Epidemiology Forecast – 2034” report delivers an in-depth understanding of leptomeningeal metastases, historical and forecasted epidemiology in the United States, EU4 (Germany, France, Italy, and Spain) and the United Kingdom, and Japan.
Leptomeningeal Metastases Understanding
Leptomeningeal metastases, also known as leptomeningeal carcinomatosis or neoplastic meningitis refer to the dissemination of malignant cells into the leptomeninges (the pia and arachnoid mater) surrounding the brain and spinal cord, as well as into the CSF. These cells disrupt normal CSF drainage pathways, resulting in fluid buildup and increased intracranial pressure. The ensuing pressure causes a range of nonspecific yet troubling symptoms, often more prominent in the morning, including headaches, nausea, vision problems, and impaired balance or coordination. Cranial nerve involvement can further cause numbness, muscle weakness, or pain. This condition typically stems from the progression of systemic cancers, most frequently those originating in the breast, lungs, gastrointestinal tract, hematologic system, melanoma, or the CNS.
Diagnosing leptomeningeal metastases begins with a comprehensive review of the patient’s medical history and a detailed physical and neurological examination. This assessment helps determine the extent of neurological involvement and raises suspicion for leptomeningeal disease. Once suspected, CSF analysis and neuroimaging become essential next steps. Tumor markers in CSF are valuable for early detection, monitoring treatment response, and predicting outcomes. General markers like lactate dehydrogenase and beta-2 microglobulin, along with specific markers such as alpha-fetoprotein (AFP), beta-human chorionic gonadotropin (ß-hCG), and carcinoembryonic antigen (CEA), can provide important diagnostic insights.
Leptomeningeal Metastases Epidemiology
The leptomeningeal metastases epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by Total Incident Cases of Leptomeningeal Metastases, Incident Cases of Leptomeningeal Metastases by Cancer Type, Leptomeningeal Metastases Cases by risk type, Gender-specific Cases of Leptomeningeal Metastases, Leptomeningeal Metastases Treated Patient Pool in the United States, EU4 countries (Germany, France, Italy, Spain) and the United Kingdom, and Japan from 2020 to 2034.
In 2024, the total incident cases of leptomeningeal metastases were approximately 120,000 in the US, reflecting its significant disease burden and the pressing need for improved diagnostic tools and more effective treatments.
In 2024, breast cancer recorded the highest incident cases of leptomeningeal metastases among all cancer types across EU4 and the UK, with approximately 30,000 cases reported.
In Germany, incident leptomeningeal metastases cases were stratified by risk classification, with 66% of patients falling under the “good risk” category and the remaining 34% categorized as “poor risk” during 2024.This distribution highlights a predominance of favorable prognostic profiles within the affected population.
KOL Views
To gaze into the epidemiology insights of the real world, we take KOLs and SMEs’ opinions working in the domain through primary research to fill the data gaps and validate our secondary research on disease incidence.
DelveInsight’s analysts connected with 10+ KOLs to gather insights; however, interviews were conducted with 5+ KOLs in the 7MM. Centers such as the Georgetown University Hospital, Department of Medical Oncology, and South Miyagi Medical Center, etc, were contacted. Their opinion helps understand and validate current disease incidence, gender involved with the disease, diagnosis rate, and diagnostic criteria.
Scope of the Report
The report covers a segment of executive summary, descriptive overview of leptomeningeal metastases, explaining its causes, signs and symptoms, and currently available diagnostic algorithms and guidelines.
Comprehensive insight has been provided into the epidemiology segments and forecasts, the future growth potential of diagnosis rate, disease progression, and diagnosis guidelines.
