Pathogenesis of peri-tumoral edema in intracranial meningiomas

Area of Science:

• Neuro-oncology
• Neoplasm Research
• Edema Pathogenesis

Background:

• Peri-tumoral edema frequently complicates intracranial meningiomas, affecting patient morbidity and mortality.
• Despite the prevalence of edema, causative factors like age, gender, tumor volume, and location have not been definitively identified.
• The underlying pathogenesis of peri-tumoral edema in meningiomas remains largely debated, even with advancements in imaging and molecular biology.

Purpose of the Study:

• To review and synthesize the current understanding of factors implicated in the pathogenesis of peri-tumoral edema in meningiomas.
• To explore various hypotheses regarding the molecular and cellular mechanisms driving edema formation.
• To identify potential therapeutic targets for managing peri-tumoral edema in meningioma patients.

Main Methods:

• Comprehensive literature review of studies investigating peri-tumoral edema in intracranial meningiomas.
• Analysis of proposed etiological factors, including molecular signaling pathways and cellular mediators.
• Synthesis of evidence on the roles of vascular endothelial growth factor, metalloproteinases, interleukins, and other potential contributors.

Main Results:

• Numerous factors have been investigated for their role in meningioma edema, but none have been conclusively proven as sole causative agents.
• Current hypotheses suggest a multifactorial pathogenesis, likely involving a complex interplay of various molecular and cellular factors.
• Vascular endothelial growth factor, matrix metalloproteinases, and interleukins are among the frequently cited potential contributors.

Conclusions:

• The pathogenesis of peri-tumoral edema in meningiomas is complex and likely multifactorial, involving a combination of investigated elements.
• Understanding these contributing factors is crucial for developing effective therapeutic strategies.
• Further research is warranted to elucidate the precise mechanisms and validate potential therapeutic targets for edema management.
