Malignant thymoma: role of radiation therapy in management. 1985

C R Kersh, and D R Eisert, and T A Hazra

Malignant thymoma is a rare tumor generally seen as an anterior mediastinal mass. Radiation therapy in ten patients with malignant thymoma diagnosed in 1968-1983 was reviewed retrospectively. Surgical therapy consisted of subtotal resection in four patients and biopsy only in six. Megavoltage irradiation in the dose range of 4,600-5,250 cGy was employed. In all symptomatic patients, palliation of presenting symptoms was achieved. In seven patients, a greater than 50% reduction in tumor mass followed radiation therapy. Local control was achieved in six patients. Three patients show no evidence of disease clinically, after a minimum follow-up study of 1 year. Radiation therapy is an important therapeutic modality in the control of malignant thymoma.

D011867	Radioisotope Teletherapy	A type of high-energy radiotherapy using a beam of gamma-radiation produced by a radioisotope source encapsulated within a teletherapy unit.	Teleradioisotope Therapy,Teletherapy, Radioisotope,Therapy, Teleradioisotope
D011882	Radiotherapy, High-Energy	Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; x-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle.

D003037	Cobalt Radioisotopes	Unstable isotopes of cobalt that decay or disintegrate emitting radiation. Co atoms with atomic weights of 54-64, except 59, are radioactive cobalt isotopes.	Radioisotopes, Cobalt
D003131	Combined Modality Therapy	The treatment of a disease or condition by several different means simultaneously or sequentially. Chemoimmunotherapy, RADIOIMMUNOTHERAPY, chemoradiotherapy, cryochemotherapy, and SALVAGE THERAPY are seen most frequently, but their combinations with each other and surgery are also used.
