Key result
Surgery and multimodal therapy remain primary treatments for aggressive intimal sarcoma driven by MDM2/PDGFRA/CDK4 amplification.
Why the study?
Intimal sarcoma is an exceptionally rare, aggressive vascular malignancy that remains frequently misdiagnosed, making updated guidance urgently needed.
Intimal sarcoma is an ultra-rare vascular malignancy with a poor prognosis that requires early recognition, molecularly guided treatment strategies, and management in specialized multidisciplinary centers.

Alerts clinicians to diagnostic delays in intimal sarcoma; leaves open optimal multimodal strategies pending prospective validation.
Purpose of review Intimal sarcoma is an exceptionally rare and aggressive vascular malignancy that remains frequently misdiagnosed. This review synthesizes recent advances in epidemiology, diagnosis, molecular characterization and treatment, highlighting why updated guidance is urgently needed. Recent findings Current literature emphasizes persistent diagnostic delays due to nonspecific clinical and radiological features. Molecular studies consistently show recurrent amplification of MDM2, PDGFRA and CDK4 as key oncogenic drivers. Surgical resection remains the only potentially curative option, although complete removal is often challenging. Retrospective data suggest that multimodal therapy, particularly anthracycline-based chemotherapy, may improve outcomes in selected patients. Targeted therapies and immunotherapy have shown limited but emerging activity in moleculary defined subgroups. Summary Despite incremental progress, prognosis remains poor, underscoring the need for earlier recognition, molecularly guided treatment strategies and clinical trial participation. Management in specialized multidisciplinary centers is essential to optimized care and advance research in this ultra-rare sarcoma.

Subires et al. (2026) conducted a review in Intimal sarcoma. Surgical resection and multimodal therapy was evaluated. Intimal sarcoma is a rare, aggressive vascular malignancy driven by MDM2, PDGFRA, and CDK4 amplification, for which surgical resection and multimodal therapy remain the primary treatment options.
