Summary
Optimal dose fractionation for high-dose-rate (HDR) brachytherapy in gynaecological cancer lacks consensus. Australian radiation oncology departments show variations in HDR brachytherapy protocols, particularly in the number of fractions used.
Area of Science:
- Oncology
- Radiation Therapy
- Gynaecological Oncology
Background:
- High-dose-rate (HDR) brachytherapy is increasingly utilized for gynaecological malignancies.
- There is a lack of established consensus regarding optimal dose fractionation schedules for HDR brachytherapy in this patient population.
Purpose of the Study:
- To survey Australian public hospital departments of radiation oncology regarding their current HDR brachytherapy protocols for gynaecological cancer.
- To present the existing protocols and identify variations in practice.
Main Methods:
- A survey was conducted among Australian public hospital departments of radiation oncology.
- Departments using or planning to use HDR brachytherapy for gynaecological cancer were included.
Main Results:
- Protocols for HDR brachytherapy in gynaecological cancer are generally similar in biological principles across surveyed departments.
- Practical aspects, specifically the number of fractions administered, show variability.
- Observed variations may stem from resource limitations or differing clinical interpretations of literature and best practices.
Conclusions:
- While biological principles are consistent, practical implementation of HDR brachytherapy for gynaecological cancer varies among Australian centers.
- Further research or guideline development may be needed to address the discrepancies in fractionation schedules.
