“Uterus with large carcinosarcoma which fills the uterine cavity and invades superficially into the myometrium”. •Now what is Carcinosarcoma ? Carcinosarcoma is a malignant tumour composed of carcinoma(Epithelial cancer) and sarcoma (cancer of connective tissues) extensively intermixed.These tumours are also called “Malignant Mixed Mullerian Tumours”. They typically arise within the endometrial cavity but, in rare cases, they may arise in the cervix. •Risk factors: Risk factors for the development of carcinosarcoma are similar to those of endometrial carcinoma and include nulliparity, advanced age, obesity, exposure to exogenous estrogens, and long-term use of tamoxifen. •Treatment: To date, no national consensus guidelines have been established for the management of uterine carcinosarcomas but the following methods are considered to take effect upto some extent: 1. Radiotherapy. 2. Chemotherapy. 3. Treating the patient with certain anti-cancerous drugs. If the above treatment options fail to work then the uterus is totally removed surgically, Called Hysterectomy.
