Sarcoma following irradiation for breast cancer. Report of three unusual cases including one malignant mesenchymoma of bone.
Three cases of sarcoma developing after irradiation for breast cancer are reported. A malignant mesenchymoma in the sternum--a combination of osteogenic sarcoma and rhabdomyosarcoma--is the first documented case of its kind occurring after radiation therapy. Of the other two tumors one was an extraskeletal osteogenic sarcoma in the soft tissues of the thoracic wall and one a rhabdomyosarcoma in the axilla.
