Conclusion:

Limitations of available GRIB data preclude informed advice regarding the minimal interval to GRIB, dose-discount, planning aims and dose constraints, techniques for image registration, dose summation, and radiobiological dose conversions. Based on available evidence, the authors perform intracavitary GRIB alone for the rare patients with central recurrences and up to ~5 mm invasion depth. Deeper lesions require interstitial or combined approach. There is no known clinical advantage of a particular dose rate, but there may be practical differences. Existent OAR dose constraints for the primary setting should be respected whenever possible but are commonly exceeded.
