Which of the following tumours metastases to heart?
Ans: a (Ca breast)Ref: Journal of Continuing Medical Education of Radiology, Annals of Oncology; Vol. 15, Issue 3"Metastases to the heart and pericardium are much more common than primary cardiac tumors and are generally associated with a poor prognosis.Tumours that are most likely to involve the heart and pericardium include cancers of the lung and breast, melanoma, and lymphoma.Tumour may involve the heart and pericardium by one of four pathways: retrograde lymphatic extension, hematogenous spread, direct contiguous extension, or transvenous extension.""In principle, every malignant tumour can metastasize to the heart. To date, only tumours of the central nervous system have not been proven to develop cardiac metastases. The most common tumours with cardiac metastatic potential are carcinomas of the lung, the breast and the esophagus, malignant lymphoma, leukemia, and malignant melanoma""Carcinoma of the breast, lung, oesophagus, pancreas, malignant melanoma, and malignant lymphoma are mentioned most frequently in the literature as the primary tumor. In fact, almost all types of tumors have occasionally metastasized to the heart."Ca urinary bladder- vascular spread is most commonly to bone, particularly axial skeleton although liver and lung metastasis do occur, usually at a very late stage. (Cushieri 4th ed. pg. 1251)In summary, metastasis are 100 times more common thanprimary tumors of the heart. Most commonly metastasizingto the heart are lung, breast, malignant melanoma, lymphoma.
