BACKGROUND AND PURPOSE:
The aim of this randomised trial was to investigate whether hyperthermia (HT) combined with interstitial brachytherapy (ISBT) has any influence on local control (LC), disease-free survival (DFS), or acute and late side effects in patients with advanced cervical cancer.
MATERIALS AND METHODS:
After radiochemotherapy, consecutive patients with cervical cancer (FIGO stage II-III) were randomly assigned to two treatment groups, either ISBT alone or ISBT combined with interstitial hyperthermia (ISHT). A total of 205 patients were included in the statistical analysis. Once a week, HT, at a temperature above 42.5°C, was administered for 45min before and during the HDR BT.
The median follow-up time was 45months (range 3-72months). An effect of hyperthermia was not detected for disease-free survival (DFS) (log-rank test: p=0.178) or for local control (LC) (p=0.991). According to Cox's analysis, HT did not significantly influence failure or interactions with potential prognostic factors for LC or DFS. Statistical differences were not observed for the distribution of early and late complications between the HT and non HT groups.
ISHT is well-tolerated and does not affect treatment-related early or late complications. Improvements in DFS and LC were not observed following the addition of ISHT to ISBT.
