“…Training organized by the American Brachytherapy Society impacted the practice of BT, and about 80% of participants utilized this training in clinical practice [ 27 ]. A survey on prostate cancer in France among 54 centers also revealed that policy-makers need to facilitate logistics and training facilities across the centers for patients to obtain benefits of optimal treatment [ 28 ]. We advocate for dedicated workshops to adequately train our peers and encourage practice of this modality.…”

Purpose This survey aimed to understand the practice pattern and attitude of Indian doctors towards prostate brachytherapy. Material and methods A 21-point questionnaire was designed in Google form and sent to radiation oncologists practicing in India, using texts, mails, and social media. Responses were collated, and descriptive statistical analysis was performed. Results A total of 212 radiation oncologists from 136 centers responded to the survey questionnaire, with majority (66%) being post-specialty training > 6 years. We found that about 44.3% ( n = 94) of respondents do not practice interstitial brachytherapy for any site, and majority (83.3%, n = 175) do not practice high-dose-rate (HDR) prostate brachytherapy. Only 2.8% ( n = 6) of doctors preferred boost by brachytherapy compared with 38.1% ( n = 80) of respondents, who favored stereotactic body radiation therapy (SBRT) boost. When asked about the indication of HDR prostate brachytherapy in Indian setting, 32.5% ( n = 67) of respondents favored monotherapy, 46.1% ( n = 95) of oncologists thought boost as a good indication, and 21.4% ( n = 44) preferred re-irradiation/salvage setting. The most cited reason for prostate brachytherapy not being popularly practiced in India was lack of training (84.8%, n = 179). It was also noted that out of 80 respondents who practiced SBRT for prostate boost, 37 would prefer HDR brachytherapy boost if given adequate training and facilities. Conclusions The present survey provided insight on practice of prostate brachytherapy in India. It is evident that majority of radiation oncologists do not practice HDR prostate brachytherapy due to lack of training and infrastructure. Indian physicians are willing to learn and start prostate brachytherapy procedures if dedicated training and workshops are organized.

“…However, brachytherapists are in short supply in brachytherapy centers. For example, while at least 3 large randomized phase III studies have shown the benefit of a brachytherapy boost for intermediate- or high-risk prostate cancers, a simulation published by the team of Nice (France) within the framework of the French Society of Radiotherapy and Oncology (Société Française de Radiothérapie et d’Oncologie – SFRO) brachytherapy group has shown that, in order to deal with new indications, each French brachytherapist trained in prostate brachytherapy would have to perform 8 implants per week in 2025 [ 1 ]. It is therefore crucial to properly train young radiation oncologists.…”

Purpose A previous survey conducted in 2012 showed that 82% of radiation oncology residents felt they were not receiving optimal brachytherapy training. With almost 10 years of hindsight, the aim was to update these results. Material and methods An anonymized questionnaire based on the 2012 survey was submitted to the 161 French residents enrolled in the 2021 French Society of Young Radiation Oncologists (Société Française des Jeunes Radiothérapeutes Oncologues – SFJRO) national brachytherapy courses. Results With a participation rate of 73%, 86% of the residents were interested in brachytherapy, but 80% consider their training in brachytherapy insufficient. 88% and 69% of the residents stated that they knew gynecological and prostate brachytherapy indications correctly, respectively. The residents have achieved proficiency in the technique of brachytherapy of vaginal vault in 36% (compared with 21% in 2012), utero-vaginal in 13% (12% in 2012), including 4% with interstitial implants, and prostate in only 4% (4% in 2012). In their brachytherapy internships, 18% of the residents declared having no role or an observational role. The main obstacles to training were the need to go to several centers to see several indications (85%), lack of brachytherapy activity in the center (72%), and the difficulty of freeing themselves from hospital duties (71%). Conclusions With results globally stable compared with 2012, brachytherapy training needs improvement. In the absence of a mandatory internship in a reference center or dedicated fellowships, residents must have protected access to training sites by favoring inter-hospital exchanges.

Objective: The objective of the study was to determine the correct CTV-PTV margin, depending on the method used to verify the PG position. In the study, 3 methods of CBCT image superimposition were assessed as based on the location of the prostate gland (CBCT images), a single gold marker, and pubic symphysis respectively.Materials and methods: The study group consisted of 30 patients undergoing irradiation therapy at the University Hospital in Zielona Góra. The therapy was delivered using the VMAT (Volumetric Modulated Arc Therapy) protocol. CBCT image-based superimposition (prostate-based alignment) was chosen as the reference method. The uncertainty of the PG positioning method was determined and the margin to be used was determined for the CBCT-based reference method. Then, changes in the position of the prostate gland relative to these determined using the single marker and pubic symphysis-based methods were determined. The CTV-PTV margin was calculated at the root of the sum of the squares for the doubled value of method uncertainty for the CBCT image-based alignment method and the value of the difference between the locations of planned and actual isocenters as determined using the method of interest and the CBCT-based alignment method for which the total number of differences accounted for 95% of all differences.Results: The CTV-PTV margins to be used when the prostate gland is positioned using the CBCT imaging, single marker, and pubic symphysis-based methods were determined. For the CBCT-based method, the following values were obtained for the Vrt, Lng, and Lat directions respectively: 0.43 cm, 0.48 cm, 0.29 cm. For the single marker-based method, the respective values were 0.7 cm, 0.88 cm, and 0.44 cm whereas for the pubic symphysis-based method these were 0.65 cm, 0.76 cm, and 0.46 cm.Conclusions: Regardless of the method, the smallest margin values were obtained for the lateral direction, with the CBCT-based method facilitating the smallest margins to be used. The largest margins were obtained using the single marker-based alignment method.
