[Comparison of conventional radium and high dose rate afterloading brachytherapy in cervix cancer].
The combination of intracavitary and external-beam radiation is the treatment of choice in advanced cervical cancer. Low-dose regimens using radium were widely abandoned in favour of high-dose-rate afterloading systems. We compared in this retrospective analysis of 550 patients the 2 different treatment modalities. We could observe neither in overall survival, nor in the incidence of side effects, any significant difference. Although the change from low- to high-dose-rate radiation therapy was not accompanied by a benefit in survival, the latter modality displayed several advantages e.g. a reduced exposure of personnel to radiation and shorter duration of confinement to bed. Patient survival rate was dependent mainly on parameters of tumour burden (FIGO stage), i.v. pyelogram or CT scan of paraaortic lymph nodes. On the other hand, neither the histological classification as epidermoid or adenocarcinoma nor the WHO grading, were useful predictors of patient outcome.
