“…Radiotherapy techniques having evolved dramatically over the last decade, it is not surprising to observe lower patient numbers for all personnel categories in actual radiotherapy practice, as it reflects the increased time demands of the more complex treatment approaches (e.g., IGRT, adaptive radiotherapy) currently used [3][4][5]. In line with this, recommendations about numerical workloads have slightly reduced since the publication of QUARTS [8,15].…”

The average personnel figures in Europe are now consistent with, or even more favourable than the QUARTS recommendations, probably reflecting a combination of better availability as such, in parallel with the current use of more complex treatments than a decade ago. A considerable variation in available personnel and delivered courses per year however persists among the highest and lowest staffing levels. This not only reflects the variation in cancer incidence and socio-economic determinants, but also the stage in technology adoption along with treatment complexity and the different professional roles and responsibilities within each country. Our data underpin the need for accurate prediction models and long-term education and training programmes.

“…This may be more important for larger patients who are more likely to roll, with longer time on the treatment couch. Time studies comparing CBCT and EPI acquisition times are scarce for breast RT, however, Perrier et al reported the times for image acquisition comparing CBCT and EPI in prostate cancer, and found that the mean times were 4.6 min (SD: 4.5 min) for CBCT and 3.6 min (SD: 1.6 min) for EPI 37. There are also treatment planning steps that can be taken to address minor daily variations and further reduce the necessity for CBCT use in tangential breast RT.…”

Comparison of setup accuracy of three different image assessment methods for tangential breast radiotherapy

IntroductionTo compare the differences in setup errors measured with electronic portal image (EPI) and cone‐beam computed tomography (CBCT) in patients undergoing tangential breast radiotherapy (RT). Relationship between setup errors, body mass index (BMI) and breast size was assessed.MethodsTwenty‐five patients undergoing postoperative RT to the breast were consented for this study. Weekly CBCT scans were acquired and retrospectively registered to the planning CT in three dimensions, first using bony anatomy for bony registration (CBCT‐B) and again using breast tissue outline for soft tissue registration (CBCT‐S). Digitally reconstructed radiographs (DRR) generated from CBCT to simulate EPI were compared to the planning DRR using bony anatomy in the V (parallel to the cranio‐caudal axis) and U (perpendicular to V) planes. The systematic (Σ) and random (σ) errors were calculated and correlated with BMI and breast size.ResultsThe systematic and random errors for EPI (Σ V = 3.7 mm, Σ U = 2.8 mm and σ V = 2.9 mm, σ U = 2.5) and CBCT‐B (Σ V = 3.5 mm, Σ U = 3.4 mm and σ V = 2.8 mm, σ U = 2.8) were of similar magnitude in the V and U planes. Similarly, the differences in setup errors for CBCT‐B and CBCT‐S in three dimensions were less than 1 mm. Only CBCT‐S setup error correlated with BMI and breast size.Conclusions CBCT and EPI show insignificant variation in their ability to detect setup error. These findings suggest no significant differences that would make one modality considered superior over the other and EPI should remain the standard of care for most patients. However, there is a correlation with breast size, BMI and setup error as detected by CBCT‐S, justifying the use of CBCT‐S for larger patients.

“…In addition, image-guidance using cone beam computed tomography (CBCT) and implanted fiducial markers further increased the precision of radiation therapy. Image-guided radiation therapy is applied most commonly in genitourinary malignancies, and incremental costs related to online image-guided treatment strategies are acceptable (1,2). Planning studies have demonstrated that IMRT treatment can reduce the dose to OAR compared to 3D-CRT, without a reduction of planning target volume (PTV) coverage (3)(4)(5)(6).…”

Cost of prostate image-guided radiation therapy: Results of a randomized trial

Abstract: The incremental costs due to different prostate IGRT strategies are relatively moderate, suggesting that daily IGRT combined with intensity-modulated RT (IMRT) could be administered in cases of high-dose radiation delivery to the prostate.
