Heart Cancer: A Rare and Serious Condition

Heart cancer, also known as primary cardiac cancer, is a rare type of cancer that begins in the heart. It's a serious condition that requires immediate medical attention.

• Types of Heart Cancer: There are two main types of heart cancer: sarcoma and carcinoma. Sarcoma is a type of cancer that originates in the soft tissues of the body, including the heart (1). Carcinoma, on the other hand, is a type of cancer that begins in the lining of the heart (5).
• Causes and Risk Factors: The exact cause of heart cancer is unknown. However, it's believed to be related to genetic mutations and environmental factors (3).
• Symptoms: The symptoms of heart cancer vary depending on where the tumor is located. Common symptoms include numbness or weakness in the face, arm, or leg, confusion or trouble speaking, and shortness of breath (7). In children, symptoms may also include chest pain, fatigue, and loss of appetite (8).
• Treatment Options: Treatment for heart cancer typically involves surgery to remove the tumor, followed by chemotherapy and radiation therapy. The goal of treatment is to cure the cancer or relieve symptoms (2).

Key Statistics

• Heart cancer is a rare condition, accounting for only 1-3% of all cancers (4).
• The prognosis for heart cancer patients is generally poor, with a five-year survival rate of around 10-20% (6).

It's essential to seek medical attention immediately if you or someone you know is experiencing symptoms that may be related to heart cancer. Early detection and treatment can significantly improve outcomes.

Common Signs and Symptoms of Heart Cancer

Heart cancer, also known as cardiac sarcoma, is a rare type of cancer that affects the heart. The symptoms of heart cancer can be similar to those of other heart conditions, making it challenging to diagnose. However, there are some common signs and symptoms to look out for.

Early Warning Signs

• Sudden, unexplained heart failure [2]
  • This is a top sign of heart cancer, where the heart suddenly stops functioning properly.
• Shortness of breath [2, 3, 8]
  • Difficulty breathing or feeling winded even when sitting still can be an early warning sign.
• Extreme fatigue [4, 9]
  • Feeling extremely tired or weak, even after resting.

Other Possible Symptoms

• Arrhythmia (irregular heartbeat) [3, 7]
  • An irregular or abnormal heart rhythm can be a symptom of heart cancer.
• Chest pain [3, 5, 8]
  • Pain or discomfort in the chest area can be a sign of heart cancer.
• Stroke (slurred speech or weakness on one side) [5]
  • Tiny pieces of cardiac sarcoma may break off and travel to other parts of the body, causing a stroke.

Additional Symptoms

• Dizziness and fainting [4]
• Fatigue [4, 9]
• Fever and chills [4]
• Heart palpitations [4]
• Joint pain [4]
• Loss of appetite [4]
• Night sweats [4]

It's essential to note that these symptoms can also be caused by other heart conditions or diseases. If you're experiencing any of these symptoms, it's crucial to consult a doctor for proper evaluation and diagnosis.

Diagnostic Tests for Heart Cancer

Heart cancer, also known as cardiac sarcoma, can be challenging to diagnose due to its rarity and non-specific symptoms. However, various diagnostic tests can help identify this condition.

• Imaging Tests: These are the primary tools used to diagnose heart tumors. They include:
  • Echocardiogram: This test uses sound waves to create a moving image of the heart's structure and function [1].
  • Cardiac MRI (Magnetic Resonance Imaging): A cardiac MRI can be very useful in diagnosing heart tumors, especially when an echocardiogram is inconclusive [2].
  • CT scans: These tests take pictures of the heart or its arteries to help doctors see whether there are any problems [3].
• Blood Tests: Blood samples can be used to look for small pieces of cancer cells' genetic material, called DNA. This test can help identify early signs that your heart may be under strain [4].
• Natriuretic Peptide Tests (BNP or NT-proBNP): These tests can also show whether the heart is under strain and can help find early signs of cardiac sarcoma [5].

In addition to these tests, a complete medical history and physical examination are essential in diagnosing heart cancer. Your doctor may also use other diagnostic procedures, such as an electrocardiogram (ECG) or exercise stress test, to rule out other conditions.

Treatment Options for Heart Cancer

Heart cancer, also known as cardiac sarcoma, is a rare and aggressive type of cancer that affects the heart muscle or blood vessels. While there are no specific treatments for heart cancer, various medications can help manage symptoms and improve quality of life.

• Chemotherapy: Chemotherapy or radiation therapy (or a combination of both) can sometimes shrink a heart tumor and relieve symptoms [1].
• Targeted Therapy: Certain targeted therapies, such as trastuzumab, may be used to treat specific types of cardiac sarcoma [5].
• Imatinib and Dasatinib: These small molecule TKIs have been used to treat chronic myelogenous leucemia (CML) and gastrointestinal stromal tumors (GISTs), but their effectiveness in treating heart cancer is not well established [6].

Challenges in Treating Heart Cancer

The treatment of heart cancer can be challenging due to the delicate nature of the heart muscle. Chemotherapy and radiation therapy can sometimes cause damage to the heart, leading to further complications.

• Cardiotoxicity: Certain chemotherapy drugs, such as doxorubicin, can cause cardiotoxicity, which can lead to heart problems [3].
• Heart Failure: Heart cancer can also lead to heart failure, a condition in which the heart is unable to pump enough blood to meet the body's needs.

New Developments in Treatment

Researchers are exploring new treatments for heart cancer, including:

• Drug-Screening Tool: A powerful new drug-screening tool has been developed at UVA Health to identify potential treatments for heart failure [4].
• Lisinopril and Carvedilol: These medications have been shown to be effective in preventing cardiotoxicity in patients receiving trastuzumab with prior exposure to anthracycline [9].

It's essential to note that the treatment of heart cancer is often individualized and may involve a combination of these therapies. Patients should consult with their healthcare provider to determine the best course of treatment for their specific condition.

Differential Diagnosis of Heart Cancer

The differential diagnosis of heart cancer, also known as cardiac tumors, involves a thorough evaluation to distinguish it from other cardiac masses such as thrombi or vegetations. This is crucial for planning the most appropriate therapy.

Key Considerations:

• Thrombi vs. Tumors: Contrast echocardiography helps in differentiating between tumor and thrombus by examining tissue perfusion [4]. In contrast to thrombi, malignant tumors tend to show evidence of rapid growth, local invasion, and presence of feeding vessels [5].
• Age and Location: Both benign and malignant tumors can be differentiated based on age of presentation, location, morphological features on echocardiography, and other clinical factors [6].
• Common Differential Diagnoses:
  • Aortic Regurgitation
  • Aortic Stenosis
  • Hypertrophic Cardiomyopathy
  • Infective Endocarditis
  • Libman-Sacks Endocarditis

Rare but Important Considerations:

• Primary vs. Metastatic Tumors: Primary cardiac tumors are rare, and the incidence is from 0.001 to 0.3% by autopsy [10]. They can be classified into three clinicopathological groups: benign congenital tumors, benign acquired tumors, and malignant tumors.
• Metastatic Cancer to the Heart: Metastatic cancer to the heart is significantly more common than primary cardiac tumors [15]. The most common cancers to metastasize to the heart are lung (37%), breast (7%), and esophageal cancers (6%) and hematologic malignancies such as lymphoma (20%).
