Abstract
Since 1972 over 100 patients were treated by frequent daily sessions of radiotherapy with a short overall time. 60Co teletherapy and 250 kV X-ray beams were used with radical or palliative dosage. The tolerance to these regimes of the skin, breast, chest wall, neck, lung and pelvis is discussed and laryngeal, hypopharyngeal, breast and bronchial tumor responses were described. Radiotherapy by multiple daily sessions is clinically possible and often an advantage. Its therapeutic ratio is not inferior to comparable regimes using longer intervals.
