肿瘤性心包炎发现在癌瘤扩散患者的尸检中10～20%肿瘤已累及心脏及心包,而心包是转移性病变的最好发部位,占心脏受累的85%。在心包转移瘤病例中,有渗出液者仅12～25%。转移癌累及心脏的发病率已有增加,可能是使用化疗及放疗增加生存期的结果。心包恶性肿瘤大多起源于心外,男性主要来自肺,女性主要来自乳房,但任何原发肿瘤均可能转移至心包。如黑色素瘤、多发性骨髓瘤及结肠腺癌等。妇科肿瘤同所有发生在膈下的原发恶性病变一样,不是恶性心包病常见的原因。转移至心包的妇癌大多数来源于子宫(宫体+宫颈)或卵巢,组织学诊断有鳞癌、腺癌和肉瘤。
Tumorous pericarditis found that 10 to 20% of the tumors in the autopsy of patients with cancer spread have involved the heart and pericardium, and the pericardium is the best site for metastatic disease, accounting for 85% of the heart involvement. In cases of pericardial metastases, there are only 12 to 25% of exudate. The incidence of metastatic cancer involving the heart has increased, probably as a result of increased survival with chemotherapy and radiotherapy. Most pericardial malignancies originate outside the heart, mainly from the lungs of men, mainly from the breast of women, but any primary tumor may be transferred to the pericardium. Such as melanoma, multiple myeloma and colon adenocarcinoma. Gynecologic cancer, like all primary malignant lesions that occur under the diaphragm, is not a common cause of malignant heart disease. The majority of women who metastasize to the pericardium come from the uterus (Palace + Cervix) or ovaries and have squamous, adenocarcinoma and sarcomas diagnosed histologically.
