• About 1,500 cases of gynechological cancer have been treated using high dose rate interacavitary irradiation since 1968 up to the present at NIRS-hospital. Five year crude survival rates of intact cervix cancer in each stages were 85.9% (67/78) in stage 1,69.3% (95/137) in stage 2,54.4% (112/206) in stage 3 and 20% (12/60) in stage 4 respectively. Incidence of moderate radiation complications in high dose intracavitary irradiation were 6.2% on rectum and 4.4% on urinary bladder respectively, however, there was no difference with that of in low dose rate intracavitary irradiation. The optimal dose to point A' were estimated as 2,900 rad in high dose rate intracavitary irradiation and 5,000 rad in low dose rate one, so the dose rate effect was 1.7. The merit or demerit of high dose rate irradiations was disscussed.
