[Regression of cervix uteri neoplasms in combined radiotherapy using low dose gamma-neutron irradiation].
The authors compared the results in the regression of uterus cervix tumour after intracavital therapy with gamma-neutron irradiation by 252cf and conventional sources of radiation gamma 226Ra in the course of a combined radiotherapy procedure. On the basis of a randomized study in 20 patients for a group it became obvious that due to the irradiation of the tumour in the initial phase of therapeutic cycle by physical dose 2 Gy of neutron component of 252Cf in the point A there was an increased regression of the tumour process causing in the 6th week since the beginning of the therapy a significant difference in the size of the tumours in both groups of patients. The time period required for 50% tumour reduction from the beginning of the therapy proved to be 23 days in patients treated with the 252Cf nuclide as compared with 48 days in the group of patients after conventional therapy.
