Abstract
Experience with twice-a-day radiation therapy program for carcinoma of the uterine cervix (FIGO Stages IIB, IIIA & IIIB) is presented. The program consists of delivering 120 cGy per fraction, two fractions a day with 6 hours between fractions. A total of 6000 cGy was delivered in 50 fractions over 5 weeks. A control group was given conventional fractionation 5000 cGy in 25 fractions, 200 cGy per fraction over 5 weeks. This feasibility study enrolled 30 patients, 15 in each group. Normal tissue reactions in skin, mucosa and bowel were recorded. The acute normal tissue reactions were enhanced in the hyperfractionation group. This was significant with regard to the bowel complications. The tumor control rate did not show any significant difference between the two groups. A short follow-up period has revealed complete healing of all acute normal tissue reactions. This study shows that further dose escalation is feasible and a study with large sample size and longer follow-up is required to reach definite conclusions.
