What is the carcinosarcoma?

Carcinosarcoma is a tumor involving epithelial cells that line the organs of the body and connective tissues such as cartilage or bone. This combination of cancer and sarcoma is relatively rare, but aggressive, which in many cases suggests a poor prognosis. A small percentage of breast cancer meets diagnostic criteria for carcinosarcoma and was sometimes found as the cause of malignant lung tumors. Its most common location is in the uterus and nearby reproductive tissues, where it represents up to five percent of the reported neoplasms. Carcinomas are cancer of epithelial cells that line the skin and many organs in the body and are quite common. Sarcomas are rare, malignant tumors of connective tissues, including bones and cartilage, and each year there are less among reported cancer cases. Both types of neoplasm are present in the same organ or tissue. The older name for this disease, the malignant mixed mesodermal tumor, reflects the fact that the connective tissue comes from the embryonic mesoderm.

in the breast isIn carcinosarcoms the most precious type of cancer. While cancers usually cause mammary gland neoplasms, sarcomas occur in less than one percent of cases. Sarcomas of soft tissues in breast fat are similar to mixed cellular cancer cancer, but are not the same in their origin or aggressiveness.

There is a significant risk that the tumor will spread from the breast to the neighboring lung tissue. Treatment with surgical removal of malignant tissue had mixed results. It is important to note that the number of cases available for the statistical analysis of forecast and the success of treatment was small.

lung carcinosarcoma, although unusual, is aggressive malignancy, which was historically difficult to diagnose from other lung cancer. Microscopic slides were once used to identify the presence of both connective and epithelial cancer, but immunohistology, improved diagnostic technique introduced in the 80's, is effectmore. The survival and recovery prognosis depends less on the cancer component than on the connective tissue tumor - sarcoma, which is often a variable that affects survival and recovery.

Some female reproductive organs contain both epithelial and connective tissue, which makes them relatively more vulnerable to cancer. In the uterus, fallopian tubes and ovaries, this condition is also called a mixed Müllerian tumor. Sometimes the sarcoma is present in the endometrium, but on other occasions it is in a muscle or cartilage outside the uterus or ovaries. They are generally found in menopause women, its causes are unclear. However, there are several known risk factors that are to share with other cancers, including estrogen therapy and radiation treatment near female reproductive organs.
