In the context of cardiac tumors, what is a key characteristic that distinguishes primary malignant tumors from metastatic lesions regarding treatment response?
In the context of cardiac tumors, what is a key characteristic that distinguishes primary malignant tumors from metastatic lesions regarding treatment response?
- Primary malignant tumors are more susceptible to surgical resection, leading to better prognosis compared to metastatic lesions.
- Both primary and metastatic lesions respond equally well to chemotherapy and radiation therapy (XRT).
- Metastatic lesions are generally more responsive to chemotherapy but resistant to XRT, unlike primary malignant tumors.
- Primary malignant tumors, with the exception of lymphoma, along with metastatic lesions, exhibit resistance to chemotherapy and XRT, leading to a poor prognosis. (correct)
A patient presents with positional symptoms suggestive of a cardiac tumor. Which of the following clinical scenarios would most strongly indicate the presence of a benign myxoma?
A patient presents with positional symptoms suggestive of a cardiac tumor. Which of the following clinical scenarios would most strongly indicate the presence of a benign myxoma?
- Gradual development of dyspnea and chest pain, unrelated to body position.
- Sudden onset of symptoms when changing position, along with an early diastolic sound resembling a 'tumor flop.' (correct)
- Anemia and significant weight loss over a short period, with no positional relation.
- Sudden onset of symptoms that are exacerbated by lying supine.
Considering the treatment strategies for primary cardiac tumors, which of the following statements is most accurate regarding surgical intervention?
Considering the treatment strategies for primary cardiac tumors, which of the following statements is most accurate regarding surgical intervention?
- Surgical resection is generally avoided for benign tumors due to their slow growth and minimal impact on cardiac function.
- Surgery for cardiac sarcomas and metastatic lesions is primarily curative, offering long-term survival in most cases.
- Most benign lesions are resectable and potentially curable with surgery. (correct)
- Surgical intervention is only considered for patients with advanced metastatic disease to alleviate symptoms.

Study Notes
- This study note covers cardiac tumors across 8 slides.
Cardiac Tumors
- Primary tumors of the heart are rare, occurring in 0.002-0.3% of autopsy series.
- Most primary cardiac tumors are benign, resectable, and potentially curable.
- With the possible exception of lymphoma, most malignant primary and metastatic cardiac lesions are resistant to chemotherapy and radiation therapy, leading to a poor prognosis.
Types of Primary Cardiac Tumors
- Benign cardiac tumors include myxoma, rhabdomyoma, papillary fibroelastoma, fibroma, lipoma, and mature teratoma.
- Malignant cardiac tumors include sarcomas (rhabdomyosarcoma, angiosarcoma), lymphoma, immature teratoma, metastatic carcinoma (lung, breast, sarcoma, melanoma, renal cell), and lymphoma.
Benign Myxoma
- A myxoma is the most common type of primary cardiac tumor in all age groups.
- Myxomas are most commonly found in the atria.
- Clinical symptoms of myxoma include fever, weight loss, anemia, and signs of systemic embolization.
- Presyncope or syncope commonly present with sudden onset of positional symptoms.
- Positional symptoms are often triggered by changes in position, such as rolling over in bed or bending over, due to gravity's effect on the tumor.
- May present with a characteristic early diastolic sound or "tumor flop".
Treatment of Cardiac Tumors
- Most benign cardiac lesions are resectable and curable.
- Surgery for cardiac sarcomas and metastatic lesions is usually for diagnostic purposes or palliative resection.
- Long-term survival for malignant cardiac tumors is generally poor.
