  • Abstract: Abstract:

    Purpose:Brain metastasis is a common complication in cancer patients. Local recurrence after total resection of metastatic brain tumor has been frequently reported. In this study, we developed a new hyperthermia device and applied it to metastatic brain tumor patients intra-operatively to study if hyperthermia treatment could reduce local tumor recurrence.

    Materials and methods:A total of 63 metastatic brain patients were enrolled in the study with an informed consent obtained from every patient. After total resection of the tumor, the hyperthermia device was applied intra-operatively to the resection cavity. The surrounding brain tissue at 5 mm in depth from the tumor resection margin was raised to 42.5 °C for a total of 60 minutes (Clinical Research Information Service Registration Number: KCT0001308).

    Results:A total of 10 local recurrences were observed in 63 patients who received hyperthermia treatment showing a local recurrence rate of 15.8%. It was significantly lower than the local recurrence rate of those who received conventional treatment (34%) when analyzed with one tailed z -test ( p value: .001). Kaplan–Meier analysis also showed a significantly lower recurrence rate in the hyperthermia treatment group ( p value: .0003). Complications included two cases of seizures and two cases of wound infection.

    Conclusions:Results of this study suggest that intra-operative hyperthermia treatment after total resection of metastatic brain tumor could reduce local recurrence of tumor. We believe that intra-operative hyperthermia treatment could be used as an adjuvant therapy to surgery and post-operative radiotherapy, or as a salvage treatment in patients who cannot receive further radiotherapy.
