Abstract
From October 1966 to March 1983, 780 cases of cervical cancer were treated with radiotherapy. Retrospective study was performed to compare between the following two groups. The first group treated from October 1966 to December 1974 included 393 cases and the second one treated from January 1975 to March 1983 included 387 cases. The mean age, stage balance and histological balance were not different between the two groups. The number of patients treated with external irradiation alone decreased in the second group. Five year-survival rate in the first group was 71.4% for stage I, 58.5% for stage II, 37.1% for stage III, 17.6% for stage IV, and in the second group, 83.7% for stage I, 71.7% for stage II, 47.9% for stage III, 0% for stage lY respectively. Therewas a significant difference (p<0.01) in the five year survival rates in stage I, II and III.
Appropriate diagnosis as well as treatment in the individual cases might be contribu-tory factors for the improvement of prognosis.
