•Clinical audits using the QUATRO methodology have been successfully carried out in all Belgian radiotherapy departments from 2011 to 2015.•National radiotherapy improvement initiatives should focus ...on quality of the facility and equipment, the development of organisational charts, and the improvement of incident and near-incident feedback.•Formal patient follow-up programs after radiotherapy delivery should be established.•Lack of training and professional development of RTTs was also pointed out as being an area needing to be improved.
A national incentive brought about the instauration of systematic clinical audits of all Belgian radiotherapy departments (n = 25) from 2011 to 2015 using the International Atomic Energy Agency QUATRO (Quality Improvement Quality Assurance Team for Radiation Oncology) methodology. The impact of these audits was evaluated and the emitted recommendations originating from the audit reports were analysed to identify areas of weakness on a national basis.
The QUATRO audits performed in each radiotherapy department gave rise to reports in which each department received a list of recommendations that it is free to implement. These audit reports were analyzed to identify common areas for which improvements were recommended. Moreover, questionnaires were sent to all departments in order to evaluate the overall usefulness of the recommendations as well as the relevancy and the actual impact of each individual recommendation.
Of the 381 emitted recommendations, 34% concerned process optimization of which a quarter involved process improvement and protocol development. Twenty-seven percent of the recommendations concerned infrastructure of which one-third was related to the quality of the equipment or facility. Nineteen and 20% of recommendations addressed department organisational and staff issues respectively.
When analysing the departments’ feedback questionnaires, 54% of the departments evaluated the audits’ recommendations as being very useful. Furthermore, 42.7% of the recommendations were found to be very relevant and 23.5% were deemed to have an important impact.
This first round of audits in Belgium allowed for the identification of common areas for improvements of practice in radiation oncology departments, with a focus on process optimization and infrastructure elements. Similarly, the audits’ emitted recommendations were globally deemed very relevant. Encouraged, by this analysis, a second cycle of audits has started in Belgium with a modified version of the QUATRO document (B-QUATRO).
COVID-19 reached Belgium in February and quickly became a major public health challenge. It is of importance to evaluate the actual impact of COVID-19 on patients and staff in Belgian radiotherapy ...departments (RTDs). This was evaluated through a weekly national survey sent to departments measuring key factors that were affected by the pandemic.
The Belgian SocieTy for Radiation Oncology (BeSTRO) together with the Belgian College for physicians in Radiation Oncology invited all 26 RTD to participate in a survey that started on March 2nd and was re- submitted weekly for 4 months to assess variations in time. The survey focused on: (1) the COVID-19 status of patients and staff; (2) the management of clinically suspected COVID patients and COVID positive patients; (3) the impact of COVID-19 on RTD activities; (4) its impact in radiotherapy indications and fractionation schemes.
Seventy-three percent of 26 RTDs completed the first survey and 57% responded to all weekly surveys. In the RTD staff, 24 members were COVID-positive of whom 67% were RTTs. Over the study period, the number of patients treated dropped by a maximum of 18.8% when compared to March 2nd. In 32.3% of COVID-positive and 54% of COVID suspected patients, treatment was continued without any interruptions. Radiotherapy indications were adapted within the 1st weeks of the survey in 47.4% of RTD, especially for urological and breast tumors. Fractionation schemes were changed in 68.4% of RTD, mainly for urological, breast, gastro-intestinal, and lung tumors.
Between March and June 2020, the COVID-19 pandemic resulted in an important decrease in treatment activity in RTD in Belgium (18.8%). The COVID-19 infection status of patients influenced the continuity of the radiotherapy schedule. Changes in indications and fractionation schedules of radiotherapy were rapidly incorporated in the different RTD.
Over the last decade, the management of locally advanced head and neck cancers (HNCs) has seen a substantial increase in the use of chemoradiation. These guidelines have been developed to assist ...Radiation TherapisTs (RTTs) in positioning, immobilisation and position verification for head and neck cancer patients.
A critical review of the literature was undertaken by the writing committee.
Based on the literature review, a survey was developed to ascertain the current positioning, immobilisation and position verification methods for head and neck radiation therapy across Europe. The survey was translated into Italian, German, Greek, Portuguese, Russian, Croatian, French and Spanish.
Guidelines were subsequently developed by the writing committee.
Results from the survey indicated that a wide variety of treatment practices and treatment verification protocols are in operation for head and neck cancer patients across Europe currently.
The guidelines developed are based on the experience and expertise of the writing committee, remaining cognisant of the variations in imaging and immobilisation techniques used currently in Europe.
These guidelines have been developed to provide RTTs with guidance on positioning, immobilisation and position verification of HNC patients. The guidelines will also provide RTTs with the means to critically reflect on their own daily clinical practice with this patient group.
Abstract PET/CT imaging modalities have been shown to be useful in the diagnosis, staging, and monitoring of malignant diseases. Its inclusion into the treatment planning process is now central to ...modern radiotherapy practice. However, it is essential to be cognisant of the factors that are necessary in order to ensure that the acquired images are consistent with the requirements for both treatment planning and treatment delivery. Essential parameters required in image acquisition for radiotherapy planning and treatment include consistencies of table tops and the use of laser light for patient set-up. But they also include the accurate definition of the patient’s initial positioning and the use of proper immobilization devices in the radiotherapy department. While determining this optimum set-up, patient psychological factors and limitations that may be due to the subsequent use of PET/CT for planning purposes need to be taken into account. Furthermore, patient set-up data need to be properly recorded and transmitted to the imaging departments. To ensure the consistency of patient set-up, the radiation therapist should ideally be directly involved in informing and positioning the patient on the PET/CT. However, a proper exchange of patient-related information can also be achieved by a close liaison between the two departments and by the use of clear detailed protocols per type of patient set-up and/or per localization of tumour site.
•The collection of quality indicators on a national level is a valuable process in steering quality improvement initiatives.•Radiotherapy specific quality indicators have been collected on a yearly ...and national basis in Belgium from 2016 until now.•The feasibility of collecting radiotherapy specific quality indicators on a national basis was demonstrated with a high level of participation.•Personalized feedback of the collected QIs have shown to guide departments in setting up quality improvement initiatives.
To promote best practice and quality of care, the Belgian College of Physicians for Radiotherapy Centers established a set of radiotherapy specific quality indicators for benchmarking on a national level. This paper describes the development, the collected QIs, the observed trends and the departments’ evaluation of this initiative.
The Donabedian approach was used, focussing on structural, process and outcome QIs. The criteria for QI selection were availability, required for low-threshold regular collection, and applicability to guidelines and good practice. The QIs were collected yearly and individualized reports were sent out to all RT departments. In 2021, a national survey was held to evaluate the ease of data collection and submission, and the perceived importance and validity of the collected QIs.
18 structural QI and 37 process and outcome parameters (n = 25 patients/pathology/department) were collected. The participation rate amounted to 95 % overall. The analysis gave a national overview of RT activity, resources, clinical practice and reported acute toxicities. The individualized reports allowed departments to benchmark their performance.
The 2021 survey indicated that the QIs were overall easy to collect, relevant and reliable. The collection of acute recorded toxicities was deemed a weak point due to inter-observer variabilities and lack of follow-up time.
QI collection on a national level is a valuable process in steering quality improvement initiatives. The feasibility and relevance was demonstrated with a high level of participation. The national initiative will continue to evolve as a quality monitoring and improvement tool.
•Reproducibility/Stability of MANIV-DIBH is non-inferior to surface-guided DIBH.•A better cardiopulmonary protection is achieved with mechanical ventilation.•Comfort and treatment time with MANIV are ...similar to surface-guided DIBH.•MANIV enables better inter-fraction heart repositioning.
Deep inspiration breath-hold (DIBH) protects critical organs-at-risk (OARs) for adjuvant breast radiotherapy. Guidance systems e.g. surface guided radiation therapy (SGRT) improve the positional breast reproducibility and stability during DIBH. In parallel, OARs sparing with DIBH is enhanced through different techniques e.g. prone position, continuous positive airway pressure (CPAP). By inducing repeated DIBH with the same level of positive pressure, mechanically-assisted and non-invasive ventilation (MANIV) could potentially combine these DIBH optimizations.
We conducted a randomized, open-label, multicenter and single-institution non-inferiority trial. Sixty-six patients eligible for adjuvant left whole-breast radiotherapy in supine position were equally assigned between mechanically-induced DIBH (MANIV-DIBH) and voluntary DIBH guided by SGRT (sDIBH). The co-primary endpoints were positional breast stability and reproducibility with a non-inferiority margin of 1 mm. Secondary endpoints were tolerance assessed daily via validated scales, treatment time, dose to OARs and their inter-fraction positional reproducibility.
Differences between both arms for positional breast reproducibility and stability occurred at a sub-millimetric level (p < 0.001 for non-inferiority). The left anterior descending artery near-max dose (14,6 ± 12,0 Gy vs. 7,7 ± 7,1 Gy, p = 0,018) and mean dose (5,0 ± 3,5 Gy vs. 3,0 ± 2,0 Gy, p = 0,009) were improved with MANIV-DIBH. The same applied for the V5Gy of the left ventricle (2,4 ± 4,1 % vs. 0,8 ± 1,6 %, p = 0,001) as well as for the left lung V20Gy (11,4 ± 2,8 % vs. 9,7 ± 2,7 %, p = 0,019) and V30Gy (8,0 ± 2,6 % vs. 6,5 ± 2,3 %, p = 0,0018). Better heart’s inter-fraction positional reproducibility was observed with MANIV-DIBH. Tolerance and treatment time were similar.
Mechanical ventilation provides the same target irradiation accuracy as with SGRT while better protecting and repositioning OARs.
In this study, we intend to compare two different setup procedures for female breast cancer patients.
Imaging in radiotherapy provides a precise localization of the tumour, increasing the accuracy of ...the treatment delivery in breast cancer.
Twenty breast cancer patients who underwent whole breast radiotherapy (WBRT) were selected for this study. Patients were divided into two groups of ten. Group one (G1) was positioned by tattoos and then the patient positioning was adjusted with the aid of AlignRT (Vision RT, London, UK). In group two (G2), patients were positioned only by tattoos. For both groups, the first 15 fractions were analyzed, a daily kilovoltage (kV) cone beam computed tomography (CBCT) image was made and then the rotational and translational displacements and, posteriorly, the systematic (Σ) and random (σ) errors were analyzed.
The comparison of CBCT displacements for the two groups showed a statistically significant difference in the translational left–right (LR) direction (ρ=0.03), considering that the procedure with AlignRT system has smaller lateral displacements. The results of systematic (Σ) and random (σ) errors showed that for translational displacements the group positioned only by tattoos (G2) demonstrated higher values of errors when compared with the group positioned with the aid of AlignRT (G1).
AlignRT could help the positioning of breast cancer patients; however, it should be used with another imaging method.
For cancer patient populations worldwide, the synchronous scale-up of diagnostics and treatments yields meaningful gains in survival and quality of life. Among advanced cancer therapies, radiotherapy ...(RT) and theranostics are key to achieving practical, high-quality, and personalized precision medicine - targeting disease manifestations of individual patients and broad populations, alike. Aiming to learn from one another across different world regions, the six country vignettes presented here depict both challenges and victories in de novo establishment or improvement of RT and theranostics infrastructure.
The International Atomic Energy Agency (IAEA) convened global RT and theranostics experts from diverse world regions and contexts to identify relevant challenges and report progress in their own six countries: Belgium, Brazil, Costa Rica, Jordan, Mongolia, and South Africa. These accounts are collated, compared, and contrasted herein.
Common challenges persist which could be more strategically assessed and addressed. A quantifiable discrepancy entails personnel. The estimated radiation oncologists (ROs), nuclear medicine physicians (NMPs), and medical physicists (MPs for RT and nuclear medicine) per million inhabitants in the six collective countries respectively range between 2.69-38.00 ROs, 1.00-26.00 NMPs, and 0.30-3.45 MPs (Table 1), reflecting country-to-country inequities which largely match World Bank country-income stratifications.
Established goals for RT and nuclear medicine advancement worldwide have proven elusive. The pace of progress could be hastened by enhanced approaches such as more sustainably phased implementation; better multinational networking to share lessons learned; routine quality and safety audits; as well as capacity building employing innovative, resource-sparing, cutting-edge technologic approaches. Bodies such as ministries of health, professional societies, and the IAEA shall serve critical roles in convening and coordinating more innovative RT and theranostics translational research, including expanding nuanced global database metrics to inform, reach, and potentiate milestones most meaningfully.

Abstract Introduction In 2007 ESTRO proposed a revision and harmonisation of the core curricula for radiation oncologists, medical physicists and RTTs to encourage harmonised education programmes for ...the professional disciplines, to facilitate mobility between EU member states, to reflect the rapid development of the professions and to secure the best evidence-based education across Europe. Material and methods Working parties for each core curriculum were established and included a broad representation with geographic spread and different experience with education from the ESTRO Educational Committee, local representatives appointed by the National Societies and support from ESTRO staff. Results The revised curricula have been presented for the ESTRO community and endorsement is ongoing. All three curricula have been changed to competency based education and training, teaching methodology and assessment and include the recent introduction of the new dose planning and delivery techniques and the integration of drugs and radiation. The curricula can be downloaded at http://www.estro-education.org/europeantraining/Pages/EuropeanCurricula.aspx. Conclusion The main objective of the ESTRO core curricula is to update and harmonise training of the radiation oncologists, medical physicists and RTTs in Europe. It is recommended that the authorities in charge of the respective training programmes throughout Europe harmonise their own curricula according to the common framework.
