Often asked by people, you see who has lung cancer, or breast cancer, gastrointestinal cancer, thyroid cancer, etc., who has never heard of a heart tumor. Why is the heart not growing cancer? Indeed, unlike other organs and tissues, human cardiomyocytes do not divide and multiply after birth. Cardiomyocytes are called “terminally differentiated cellsâ€, that is, the lifespan of such cells is the same as human beings. After birth, it no longer divides and proliferates, its quantity remains unchanged, it is highly differentiated, and it has only certain functions. The genes involved in division and proliferation cannot be expressed, so it is difficult for cardiomyocytes to develop primary cancer. At the same time, the blood flow in the heart is extremely fast. It is also difficult for other cancer cells to fall into the blood to deposit cancer on the heart, because the transfer of cancer cells requires not only the easy fallout of cancer cells, but also the need for cancer cells to be in the body. The local area is under the development of the camp. Although there are nervous system, fat, mesothelium and other tissues in the heart, the blood flow in the heart is too fast. Most cancer cells have no chance to rest their feet and they are brought out of the heart by the blood. . Therefore, the heart is also a rare area for metastasis. What tumors may the heart itself grow? However, rare is rare, the heart can still grow tumors. Cardiac myxoma Cardiac myxoma is the most common benign tumor of the heart. Nearly 75% of atrial myxoma is confined to the left atrium and interatrial septum. In general, cardiac myxoma often has a "pedicle". Ultrasound can be seen that this "pedicle" suspends the myxoma on the atrial side. When the heart is dilated, the myxoma can be prolapsed through the mitral valve to the left ventricle. Myxoma is more common in women aged 30-60 years. 90% of patients may have systemic symptoms such as weight loss, fever, anemia, elevated erythrocyte sedimentation rate, and elevated levels of immunoglobulins (usually IgG). Arterial embolism can occur in 50% of patients, involving the brain (50% of embolism), heart, kidney, limb extremities, and aortic branches. Especially when young people have embolism and heart rhythm is sinus rhythm, they should be highly alert to cardiac myxoma. Left atrial myxoma, mitral or pulmonary venous obstruction, secondary right heart failure due to pulmonary vein or pulmonary hypertension. Symptoms of left atrial myxoma include difficulty breathing, sitting breathing, and symptoms of acute pulmonary edema, hemoptysis, dizziness, and syncope. Occasionally, sudden death can occur. Changes in the patient's position may also produce symptoms. Once confirmed, surgical myxomatosis should be performed. Primary cardiac malignancy Almost all primary cardiac malignancies are sarcomas - the most common angiosarcoma, often originating in the right atrium or pericardium. 25% of angiosarcomas can cause valvular obstruction, right heart failure, and hemorrhagic pericardial effusion leading to pericardial tamponade. Surgical removal of tumors, radiotherapy, and chemotherapy can alleviate some symptoms. Pericardial tumor Because 75% of pericardial cysts are asymptomatic, they are often found when they are examined by chance. Cysts are mostly located in the right heart angle, and echocardiography and CT examination can identify pericardial cysts and solid tumors. Mesothelioma, a pericardial malignancy, may present severe conditions including pericarditis, restrictive pericardial disease, and inferior vena cava obstruction. Histological examination of pericardial effusion is often helpful in diagnosis. The prognosis of mesothelioma is poor. Roughly resected mesothelioma by surgery, radiotherapy and chemotherapy can only temporarily relieve symptoms.
