Intimal sarcoma, review and future perspectives.

Area of Science:

• Vascular Oncology
• Rare Cancers
• Molecular Pathology

Background:

• Intimal sarcoma is an aggressive vascular malignancy.
• It is characterized by frequent misdiagnosis due to nonspecific clinical and radiological features.
• Early recognition and specialized management are critical.

Purpose of the Study:

• To review recent advances in the epidemiology, diagnosis, molecular characterization, and treatment of intimal sarcoma.
• To highlight the urgent need for updated clinical guidance.
• To emphasize the importance of multidisciplinary care in specialized centers.

Main Methods:

• Literature review synthesizing current research on intimal sarcoma.
• Analysis of diagnostic challenges, molecular drivers, and treatment modalities.
• Evaluation of retrospective data on therapeutic outcomes.

Main Results:

• Diagnostic delays are common due to nonspecific presentation.
• Key oncogenic drivers include recurrent amplification of MDM2, PDGFRA, and CDK4.
• Surgical resection is the only potentially curative option, often requiring multimodal therapy.
• Anthracycline-based chemotherapy may improve outcomes; targeted therapies and immunotherapy show emerging activity.

Conclusions:

• Prognosis for intimal sarcoma remains poor despite progress.
• Earlier recognition and molecularly guided treatments are essential.
• Participation in clinical trials and management at specialized centers are vital for optimizing care and advancing research.
