Intrauterine high dose rate afterloading brachytherapy: experience of fractionated therapy using a cervical sleeve technique.
Using a standard three-channel Manchester-type tube and ovoid high dose rate applicator system, 46 consecutive patients have been treated for carcinoma of the cervix or endometrium. To facilitate fractionated treatments using high dose rate afterloading, a technique has been developed using an indwelling cervical sleeve inserted under an initial general anaesthetic. All patients received at least two insertions; in five patients we have delivered a total of six consecutive fractions on an outpatient basis without anaesthesia once the sleeve was in situ. Acute morbidity related to the procedure was some degree of uterine pain, which was relieved with nitrous oxide inhalation, and mild, but self-limiting, vaginal discharge. Complete late morbidity data are not yet available, but, in 30% of 25 evaluable patients, minor problems have been observed, particularly vaginal oedema and stenosis. Only one major late event has required surgery. Fractionated afterloading intrauterine brachytherapy can be delivered on an outpatient basis without anaesthesia using this cervical sleeve technique.
