Meningiomas, which arise from the sphenoid wing and spread to the orbital cavity and inner cranial region, Spheno-Orbital Meningiomas (SOMs) are a unique type of meningiomas. Protheragen offers comprehensive diagnostics and therapeutics development services for SOM, leveraging cutting-edge technologies and expertise in molecular biology and drug development.
Introduction to Spheno-Orbital Meningioma (SOM)
Spheno-orbital meningioma, SOM for short, is an uncommon form of meningioma that develops on the sphenoid wing and projects into the orbit. While benign in nature, SOMs may severely impinge on the quality of life of patients because of their placement, causing much morbidity due to their severe location in regard to the eyes, alongside proptosis and various neurological deficits. SOMs constitute about nine percent of intracranial meningiomas and are usually found in middle-aged females. Their complex anatomical location poses unique challenges for diagnosis and therapy, necessitating advanced therapeutic strategies.

et al., 2024)
The development of Spheno-Orbital Meningiomas stems from several factors ranging from genetic and anatomical to environmental influences. These tumors arise from the arachnoid cap cells of the meninges and demonstrate various degrees of histological manifestations, such as the WHO Grade II meningiomas, which are aggressive and have high recurrence rates. The tumors also extend posteriorly and laterally due to the rich vascular supply of the sphenoid wing and its closeness to the orbit and skull base.
Molecular Diagnostics of Spheno-Orbital Meningioma (SOM)
- Next-Generation Sequencing (NGS): NGS facilitates the detection of oncogenic somatic mutations, for instance, NF2 and TRAF7, which are imperative for the development of tailored therapies.
- Immunohistochemistry (IHC): IHC assists in the detection of protein markers like progesterone receptors and VEGF, contributing to tumor classification and prognostication.
Therapeutics Development for Spheno-Orbital Meningioma (SOM)
SOM growth is managed, and tumor vascularity is reduced with the administration of Bevacizumab which is a monoclonal antibody targeting VEGF. This suggests that the antibody has some degree of effectiveness against SOMs.
The suppression of tumor growth in SOMs with the NF2 mutation is being studied with Everolimus, a powerful mTOR inhibitor.
In SOMs with a positive progesterone receptor, an anti-tumor effect is observed with Mifepristone, which is a progesterone receptor antagonist.
