Primary Cardiac Osteosarcoma: Epidemiology, Diagnosis, and Management - A Narrative Review

Area of Science:

• Cardiovascular Pathology
• Oncology
• Rare Cancers

Background:

• Primary cardiac sarcomas are rare, with osteosarcoma being one of the rarest subtypes.
• Fewer than 60 cases of primary cardiac osteosarcoma have been reported.
• Diagnosis is challenging due to non-specific clinical presentations mimicking common cardiac diseases.

Purpose of the Study:

• To provide an overview of primary cardiac osteosarcoma.
• To discuss epidemiology, clinical presentation, and management strategies.
• To highlight case reports for understanding variability and complexity.

Main Methods:

• Narrative review of literature.
• Analysis of epidemiological data.
• Examination of clinical case reports and management strategies.

Main Results:

• Clinical presentation often mimics heart failure, mitral stenosis, or coronary artery disease.
• Transthoracic echocardiography is the primary diagnostic imaging modality.
• Surgical resection is the preferred initial treatment for localized disease.

Conclusions:

• Standardized treatment guidelines for primary cardiac osteosarcoma are difficult to establish due to its rarity.
• Current management involves surgery, with potential use of chemotherapy and radiation therapy.
• Improved understanding and management strategies are needed to improve the poor overall prognosis.
