From September, 1974 through December, 1979, a total of 249 patients with carcinoma of the cervix uteri Stage IIb and III were randomly allocated to either remotely controlled high-dose-rate intracavitary radiotherapy or manual afterloading low-dose-rate therapy, with radiotherapy of 20 Gy in 2 weeks to Point A to whole pelvis and 40 Gy in 4 weeks to the parametria. The dose to Point A by intracavitary radiotherapy was 40-60 Gy with one or two fractions in the low-dose-rate group and 30 Gy for the high-dose-rate group by 3 fractions with a once a week schedule. The purpose of this paper is to compare the results between the groups and to clarify the problems in the high-dose-rate group clinically. The local control rate was higher in the high-dose-rate group; however, the complication rate was also higher in this group than in the low-dose-rate group. The dose schedule and the place of rectal dose measurement is discussed. The overall cumulative survival rate was nearly the same in both groups (55% at 5 years), although some difference was noted in each stage. The most common cause of death was distant metastasis outside the pelvis and the second most common was intercurrent disease in Stage IIb and local failure in Stage III.
