Abstract:
:Twenty patients with multiple or recurrent superficial head and facial cancer were treated with low-megavoltage electron-beam therapy, using a readily adaptable polystyrene shield assembly with interchangeable collimators. Patient set-up times were reduced, treatment was simplified, and flexibility of therapy was achieved. Therapeutic response was excellent even in patients with extensive primary or recurrent skin cancer requiring large-field irradiation.
