Local Ablation in the Management of Primary and Metastatic Gynecologic Cancers: A Review of Evidence and Indications for Stereotactic Body Radiotherapy (SBRT)

July 2, 2025

The role of SBRT in local ablation of oligometastatic or locally progressive gynecologic cancers will be reviewed. Ongoing studies and future directions in utilization of SBRT in this patient group will also be discussed. SBRT as a primary boost for gynecologic cancers will be evaluated, in scenarios where brachytherapy is not desired or possible. Patient cases will be examined including possible challenges and strategies to address them. SBRT as re-treatment for recurrences in the pelvis or para-aortic region, including experience with radiotherapy doses utilized and toxicity will be discussed.

Learning objectives:

1.        Review current evidence in the role of Stereotactic body radiotherapy (SBRT)  for oligometastatic gynecologic cancers

2.        Discuss clinical cases where SBRT may be considered as a primary boost for gynecologic cancers, where brachytherapy is not desirable or feasible

3.        Understand current literature regarding SBRT for re-irradiation in the pelvis for recurrences of gynecologic cancers

Dr Lalondrelle is a Consultant Clinical Oncologist at the Royal Marsden Hospital, specialising in the treatment of gynaecological cancers with radiotherapy, brachytherapy and chemotherapy. She also holds Honorary Faculty status at the Institute of Cancer Research. She qualified from the University of Southampton in 1998 and trained in oncology at The Royal Marsden and in South West Thames, completing her research thesis in adaptive radiotherapy for pelvic cancers at the University of London.

Dr Lalondrelle is actively involved in clinical research with particular interests in radiotherapy technologies, particularly stereotactic radiotherapy and adaptive planning to improve accuracy and reduce toxicity. She is the global lead for the gynaecology group of the MRlinac consortium.  She is also involved in image-guided brachytherapy, the assessment of functional imaging for radiotherapy planning and the combination of biological and immunotherapy agents with radiotherapy.
