What is a carcinoma sarcoma?

Carcinosarcomas are malignant tumors that consist of a mixture of carcinoma (or epithelial cancer) and sarcoma (or mesenchymal / connective tissue cancer). Carcinosarcomas are rare tumors, and can arise in diverse organs, such as the skin, salivary glands, lungs, the esophagus, pancreas, colon, uterus and ovaries.

What is the pathophysiology of carcinosarcoma?

Carcinosarcomas are rare tumors, and can arise in diverse organs, such as the skin, salivary glands, lungs, the esophagus, pancreas, colon, uterus and ovaries. Four main hypotheses have been proposed for the cellular origins of carcinosarcoma, based largely on the pathology of the disease.

What is the main cause of cancer?

There is no one single cause for cancer. Scientists believe that it is the interaction of many factors together that produces cancer. The factors involved may be genetic, environmental, or constitutional characteristics of the individual. Diagnosis, treatment, and prognosis for childhood cancers are different than for adult cancers.

What is a carcinosarcoma of the endometrium?

Micrograph of a carcinosarcoma of the endometrium. H&E stain. Carcinosarcomas are malignant tumors that consist of a mixture of carcinoma (or epithelial cancer) and sarcoma (or mesenchymal / connective tissue cancer).

With five-year survival in the order of 30–39%, outcomes are comparatively worse than those for both grade 3 endometrial cancers and uterine sarcomas. Surgery, including hysterectomy bilateral salpingo-oophorectomy and pelvic lymph node dissection is the primary treatment for UCS.

Is uterine carcinosarcoma curable?

Surgery alone can cure uterine sarcoma if the tumor hasn't spread outside of the uterus. In most cases we recommend other therapies only if the cancer has spread (metastasized) to other organs. These approaches can include chemotherapy, hormone therapy, or radiation therapy.

About two thirds (66%) of women who are diagnosed with early-stage leiomyosarcoma survive 5 years or longer. The prognosis worsens if the cancer has spread beyond the uterus, declining to a 5-year survival rate of 13 to 34%. When uterine sarcoma spreads, it often metastasizes to the lungs or the abdomen.

What are the four hypotheses for carcinosarcoma?

First, the collision tumor hypothesis, which proposes the collision of two independent tumors resulting in a single neoplasm, based on the observation that skin cancers and superficial malignant fibrous histiocytomas are commonly seen in patients with sun-damaged skin; second, the composition hypothesis , which suggests that the mesenchymal component represents a pseudosarcomatous reaction to the epithelial malignancy ; third, the combination hypothesis, which suggests that both the epithelial and mesenchymal components of the tumor arise from a common pluripotential stem cell that undergoes divergent differentiation ; and fourth, the conversion/divergence hypothesis, which argues that the sarcomatous component of the tumor represents a metaplastic sarcomatous transformation of the epithelial component. Despite the remaining uncertainty on the mechanisms that generate these tumors, recent immunohistochemical, ultrastructural, and molecular genetic studies suggest and favor the notion of monoclonality in carcinosarcoma. In addition, identical p53 and KRAS mutations have been identified in both epithelial and mesenchymal components of carcinosarcoma, findings that suggest an early alteration in the histogenesis of the tumor with late transformation or degeneration of the epithelial component into the sarcomatous component.

What is a micrograph of a carcinosarcoma?

What causes sarcomas to form?

It's not clear what causes most sarcomas. In general, cancer forms when changes (mutations) happen in the DNA within cells.

What is the cause of childhood cancer?

Childhood cancers often occur or begin in the stem cells, which are simple cells capable of producing other types of specialized cells that the body needs. A sporadic (occurs by chance) cell change or mutation is usually what causes childhood cancer. In adults, the type of cell that becomes cancerous is usually an epithelial cell.

In adults, the type of cell that becomes cancerous is usually an epithelial cell. Epithelial cells line the body cavity and cover the body surface. Cancer occurs from environmental exposures to these cells over time. Adult cancers are sometimes referred to as acquired for this reason.

Why do stem cells make abnormal cells?

One theory suggests that the cells in the bone marrow, the stem cells, become damaged or defective, so when they reproduce to make more cells, they make abnormal cells or cancer cells.
