title: Comparison of skin erythemas under two different fractionation schemes.
abstract: This paper reports the results of a prospective clinical trial comparing 200 rads daily five times weekly for four weeks with 400 rads twice weekly for four weeks. Total dose in the first case was 4,000 rads and in the second 3,200 rads. Thirty patients threated palliatively for bronchial carcinoma are involved in this report. Treatment was given at 220 kV and the intensity of skin erythema at the end of the treatment was the measure of comparison. Generally 200 rads daily five times weekly for four weeks produced more intense erythema than the other scheme used.
