Abstract
In an unselected group of 51 patients with carcinoma of the uterine cervix stage II vitamin A absorption tests were performed before treatment and at intervals during radiation treatment. All the patients received a combination of external fractionated betatron treatments to external pelvic fields and local radium applications by a modified Paris technique. The results show a reduced absorption of vitamin A during radiotherapy, with large individual variations but no apparent progression with increasing radiation dosage.
