Is There Gender Disparity in RANZCR Radiation Oncology Grants and Prizes Success?
J Med Imaging Radiat Oncol
January 2025
Introduction: Recent RANZCR studies have demonstrated gender disparity in research publication output of both radiation oncology (RO) trainees and specialists, favouring men. The purpose of this project was to examine success rates by gender of grant and prize (G&P) submissions to the RO Research Committee (RORC) to determine if anything needs to be done about the appraisal process to potentially address that disparity.
Methods: College records between 2011 and 2024 (where applicable) were searched by gender for one RO trainee, and two other research manuscript prizes, and two research grant rounds.
Article Synopsis
- The study followed patients with early-stage follicular lymphoma (ESFL) who were treated with involved field radiotherapy (IFRT) alone or combined with chemotherapy (cyclophosphamide/vincristine/prednisolone) and later added rituximab to the treatment, analyzing its effects over an 11.3-year period.* -
- Results showed that those receiving IFRT plus rituximab (IFRT + R-CVP) had significantly better progression-free survival rates (62% vs. 43%) compared to IFRT alone, even though overall survival rates didn’t differ significantly.* -
- Additionally, higher expression of the CD8A gene in biopsy samples was associated with improved outcomes, suggesting that immune
Publication output of RANZCR radiation oncologists in 2022-23.

Introduction: The purpose of this work was to determine the current publication output of Royal Australian and New Zealand College of Radiologists radiation oncologists (ROs) to serve as a baseline contributing to future assessment of the effectiveness of the College's Research Action Plan 2024-26.
Methods: An online survey was sent to all ROs in the College's member database in March-April 2024 requesting a list of publications between 2022 and 2023. A PubMed search was performed to cross-check the self-reported publications.
Article Synopsis
- The study aimed to assess the use of various palliative radiation therapy techniques across Australia and New Zealand, focusing on the preferences of radiation oncology practitioners.
- An anonymous online survey was conducted with 146 radiation oncology fellows, revealing that many prefer advanced techniques like stereotactic body radiation therapy for specific cancer cases, though there is considerable variation in practice between Australia and New Zealand.
- Results showed that New Zealand practitioners are more likely to use basic technologies due to limitations in the availability of advanced options and waiting lists, which impacts patient treatment choices.
Research productivity of RANZCR radiation oncology trainees from 2014 to 2023.

Introduction: The aim of this study was to describe the research productivity among RANZCR Radiation Oncology (RO) trainees.
Methods: Publicly available data on RO fellows, who were awarded the RANZCR fellowship between July 2014 and June 2023, was extracted from the RANZCR Annual Reports. Fellows who had qualified overseas and did not undertake full RANZCR training were excluded.
