“…This department has an MRI scanner in the radiotherapy centre. Use and expansion of soft tissue imaging throughout Australia and New Zealand compares favourably to other parts of the world, with uptake exceeding most other countries and regions, Table . The most notable increase in soft tissue imaging has been in the use of ultrasound to aid applicator insertion (86%) and treatment planning (29%).…”

“…Use and expansion of soft tissue imaging throughout Australia and New Zealand compares favourably to other parts of the world, with uptake exceeding most other countries and regions, Table 3. 17,[21][22][23][24][25][26][27] The most notable increase in soft tissue imaging has been in the use of ultrasound to aid applicator insertion (86%) and treatment planning (29%). While many practitioners have reported on the utility of using ultrasound for difficult insertions, Small et al recommend using ultrasound for all insertions as they felt uterine perforation was possible in any patient.…”

Patterns of practice survey for brachytherapy for cervix cancer in Australia and New Zealand

Brachytherapy remains an integral component of definitive treatment for cervix cancer in Australia and New Zealand. There was increased use of soft tissue imaging modalities with emphasis on verification; high rates of volumetric planning, and adherence to a defined overall treatment period. Brachytherapy was not substituted with other EBRT modalities. Despite this, there remain barriers to implementation of image-guided brachytherapy.

“…The fast developments of image-guided adaptive treatment of LACC induces changing 'Patterns of care' [14][15][16][17][18]. The importance of training, audits, and continuous education is widely recognized, and sharing experiences (joys and pitfalls) for chosen approaches can boost clinical implementation.…”

To report on the ''Dutch Quality Improvement Project" regarding external beam (EBRT) and brachytherapy (BT) contouring and treatment planning for locally advanced cervical cancer (LACC). Material and methods: Two rounds of three workshops were organized. Data from two patients with LACC were made available for homework exercises. Contouring and treatment planning was asked for according to the EMBRACE-II protocol. The submissions were analysed and the results were addressed during the workshops. Results: Almost all invited centres participated. EBRT contouring guidelines were followed within acceptable range, with major effort needed with regard to the ITV concept. BT contouring was of good quality, with especially small discrepancies for centres already participating in EMBRACE. EBRT treatment planning results improved between workshops with more centres being able to fulfil the planning aims. Guidance was especially necessary to improve the coverage probability planning for affected nodes. For BT planning prioritizing between target coverage and OAR sparing improved over time; the variation in dose to vaginal points remained considerable, as did variation in loading patterns and spatial dose distribution. The project was highly appreciated by all participants. Conclusion: Homework and workshop activities provide a suitable platform for discussion, exchange of experience and improvement of quality and conformity. Due to this project, radiotherapy for LACC can be administered with better and more comparable quality throughout the Netherlands.

“…Among the therapeutic options, recent studies have indicated that intracavitary brachytherapy (BT) has been shown to increase survival and local control of tumours in addition to external beam radiation therapy . BT is a type of treatment modality that evolved from 2D‐based dosimetry using point‐based dosing to 3D‐based volumetric planning . Volumetric planning, conducted before treatment, could increase the precision of radiation dose delivery by improving the tumour definition and adjacent normal tissues.…”

Comparison of accuracy and long‐term prognosis between computed tomography‐based and magnetic resonance imaging‐based brachytherapy for cervical cancer: A meta‐analysis

High-dose-rate brachytherapy (HDR-BT) has been shown to play an important role in the treatment of cervical cancer patients. The aim of this systematic review and meta-analysis was to compare the dose parameters and long-term effects of MRI-based, CT-based and hybrid imaging (MRI/CT)-based volumetric planning. A systematic search was conducted to identify the clinical studies of BT treatment on cervical cancer patients. After study selection, a total of 13 clinical studies were enrolled for further analysis. No obvious differences were observed among the treatment parameters and the patients included. In detail, no significant difference was observed among these three techniques of volumetric planning in the parameters of high-risk clinical target volume (HR-CTV), total dose of D90 or mean fraction dose of D90. Meanwhile, MRIbased planning was superior to CT-based treatment in the total dose D2cc to organs at risk (OAR) for the bladder, rectum and sigmoid. Furthermore, no significant difference was observed among MRI-, CT-or hybrid-based treatments with the mean fraction dose D2cc to OAR for the bladder, rectum or sigmoid. In conclusion, MRI provides good anatomical delineation of the relevant HR-CTV and OAR, and performed better in the analyses of dose parameters compared with CT. At least one MR image is required to assess the tumour extension, with clinical findings and MRI information facilitating much more accurate CT-based contouring.
