Abstract:
Meningeal metastasis (LM) is commonly seen in the advanced stages of cancer patients, often leading to a rapid decline in survival time and quality of life. Currently, there is still a lack of standardized treatments. Oncolytic viruses (OVs) are a class of emerging cancer therapeutics with the advantages of selectively replicating in cancer cells, delivering various eukaryotic transgenes, inducing immunogenic cell death, and promoting anti-tumor immunity. Some studies applying OVs intrathoracically or intraperitoneally for the treatment of malignant pleural and peritoneal effusions have shown promising therapeutic effects. If OVs could be applied to treat LM, it would bring significant survival benefits to patients with LM. In this review, we analyzed past research on the use of viruses to treat meningeal metastasis, summarized the efficacy and safety demonstrated by the research results, and analyzed the feasibility of oncolytic virus therapy for meningeal metastasis. We also summarized the existing data to provide guidance for the development of OVs that can be injected into the cerebrospinal fluid (CSF).
Insights
Oncolytic viruses (OVs) show promise for treating meningeal metastasis (LM), a severe cancer complication. This review explores OV therapy
Area of Science:
- Oncology
- Virology
- Cancer Therapeutics
Background:
- Meningeal metastasis (LM) significantly reduces survival and quality of life in advanced cancer patients.
- Standardized treatments for LM are currently lacking.
- Oncolytic viruses (OVs) offer selective cancer cell replication, transgene delivery, and immune stimulation.
Purpose of the Study:
- To review existing research on viral therapies for meningeal metastasis.
- To evaluate the efficacy and safety of oncolytic virus therapy for LM.
- To assess the feasibility of using OVs to treat meningeal metastasis and guide future development for cerebrospinal fluid (CSF) injection.
Main Methods:
- Comprehensive literature review of studies investigating viral treatments for meningeal metastasis.
- Analysis of reported efficacy and safety data from preclinical and clinical research.
- Assessment of the potential for oncolytic virus therapy in the context of LM treatment.
Main Results:
- Previous studies show promising therapeutic effects of OVs in treating malignant effusions (pleural and peritoneal).
- The review synthesizes data on the potential benefits and challenges of applying OVs to treat LM.
- Existing data suggests feasibility for developing OVs for direct administration into the cerebrospinal fluid (CSF).
Conclusions:
- Oncolytic virus therapy presents a potential new avenue for treating meningeal metastasis.
- Further research and development are needed to optimize OVs for CSF delivery and clinical application in LM.
- Successful OV application could significantly improve survival and quality of life for patients with LM.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
