Teratocarcinoma of the brain -- a treatable disease?

Teratocarcinoma of the brain is a rare teratoid tumor. Less than 100 cases have been previously reported and only 4 were patients with tumors in the lateral ventricular system. At the Children's Hospital of Philadelphia, 2 patients with teratocarcinoma of the lateral ventricle of the brain have been treated in the past 5 years and both are long-term survivors. A third patient with a recurrence at University Hospital is now receiving chemotherapy. Our experience suggests that a combination of radical surgery, supervoltage radiotherapy and chemotherapy may be successful in controlling these neoplasms. Furthermore, since there is increasing evidence that they have a strong histologic relationship to the embryonal carcinomas that arise in the testes and elsewhere, it appears logical to apply chemotherapeutic strategies to these intracranial neoplasms based on experience with such tumors located in other regions of the body.
