[Problems in the standardization of radiotherapy in cervical cancer]

In Japan there exists a interinstitutional difference in the response rate of cervical cancer, which is ascribed to the lack of intracavitary radiotherapy instruments. Provided the standardized treatment schedules are followed in all institutes, the over all responses will be definitely improved. Currently there are two major problems to be solved. Firstly, we have discussed IOR and hyperthermia to individualize locally advanced cervical cancers which are excluded from current standardized treatment method. Next we discussed indications for high dose rate intracavitary brachytherapy and the dose fractionation of it in relation to external beams.
