Preliminary analysis of failures in the radiotherapy of uterine cervix cancer with a dynamic dose-fractionation in combination with breathing oxygen at ambient pressure.
Complementary to a previous preliminary analysis of the results obtained in treating head and neck tumors, this paper summarizes observations in testing uterine cervix cancers with a dynamic dose-fractionation regime using Cobalt 60 radiation in combination with oxygen breathing at ambient pressure. A total of 30 cases in different stages are reviewed which had no treatment prior to radiotherapy. In agreement with previous observations, normal tissue reactions were decreased in comparison to those seen after conventional dose-fractionation. Exophytic type of tumors with relatively good vascularization appears to react better to the treatment then less vascularized endophytic tumors. For the evaluation of the possible role of the dynamic fractionation in these results collection of further data is needed.
