Second Primary Cancer after Radiotherapy for Cervical Cancer

Radiation is a treatment for many gynecological malignancies, especially locally advanced cervical cancer. Development of sarcoma due to previous radiation occurs very rarely. They develop within the radiation field. We report a case of carcinosarcoma in our patient developed 8 years after the radiotherapy (RT) that she received in the form of external beam radiation and intracavitary RT along with concomitant chemotherapy consisting of cisplatin. Although the development of secondary primary cancer is rare, for every patient who receives radiation for treatment of cancer, close follow-up is recommended as they may have viable endometrium.
