“…(3) t-IMRT dose distribution was superior to t-VMAT [Figure 1a - f and 2 ], and (4) IMRT generated the flash margin more easily than VMAT. [ 22 ] In our clinical practice, it is mandatory to write the tumor’s quadrant (a permutation of upper-lower-inner-outer). When the treatment plan is complete, the treatment planner and clinicians double-check that the noted tumor quadrant and surgical clip, if any, are adequately covered.…”

“…More importantly, in IMRT, generating the flash margin is very simple, whereas in VMAT, it requires the addition of an additional virtual target volume. [ 22 ] It is difficult for us to burden the treatment planner with additional contouring to generate the flash margin in a tertiary cancer care hospital with high patient footfall. If breast cancer cases are excluded, we have a 95% VMAT compliance rate for any other planning, including palliative treatments.…”

This article aims to identify, through a literature review, the best intensity-modulated technique (IMRT)/volumetric-modulated arc therapy (VMAT) for the breast/chest wall (Br/CW) as a function of the treatment planning system (TPS) and present the institutional dosimetric data for the same. A PubMed search was conducted following intensity-modulated irradiation techniques (IMRT) presented in the study: field-in-field (FiF), tangential IMRT (t-IMRT), multi-field IMRT, tangential VMAT (t-VMAT), half-arc VMAT (HA-VMAT), and large arc VMAT (LA-VMAT). The literature with at least one arm VMAT is included in this study. A total of 370 articles were identified between 2010 and 2022, out of which 19 articles were found to be unique. These articles were classified in terms of the TPS used: Eclipse (9), Monaco (6), RayStation (2), Pinnacle (1), and one unidentified TPS. Based on the literature review, dosimetric attributes, and second cancer risk analysis (SCRA), t-IMRT was found to be the most preferable technique in Eclipse, Pinnacle, and RayStation TPS. However, for Monaco TPS, t-VMAT (approximately 30° tangential arc) offers better dose coverage with lower organ-at-risk (OAR) doses. In terms of OAR doses and SCRA, LA-VMAT (≥210°) and HA-VMAT (180°) are avoidable techniques in any TPS, and FiF should be preferred over these two techniques. In our present institution, which uses the Eclipse TPS, data for 300 patients treated with t-IMRT were collected. The data included beam angle, monitor unit [MU], target coverage (D95% and V105% [cc]), and analysis of the maximum (%), and mean dose (%) of the OAR. t-IMRT utilizes two medial and three lateral tangential beams placed at a spread of approximately 10° and 20°, respectively. The results showed a D95% of 96.3 ± 1.2% and a V105% of 4.9 ± 7.0 cc. The mean doses to the heart and ipsilateral lung were 10.1 ± 20.9% and 11.4 ± 10.2%, respectively. The mean MU was 1282.7 ± 453.4. Based on the findings, the most preferred intensity-modulated technique for Eclipse, Pinnacle, and RayStation is t-IMRT, while for Monaco, it is t-VMAT. The data from the Eclipse planning system demonstrate a satisfactory dosimetric outcome for t-IMRT. However, the use of VMAT techniques employing an arc angle between 180° and 210° or higher is strongly discouraged.

Publishing papers in journals has long been an important way to exchange ideas and propagate knowledge. Recently, open access (OA) journals have gained growing attention as they provide greater accessibility to a wider guidance. However, the difference in the financial model between the OA journals and conventional subscription journals has brought many controversies. Some think that the OA financial model can facilitate the growth of medical physics in low-and middle-income countries (LMICs), while others have significant concerns about financial burdens that OA can bring to potential authors will hinder medical physics research in LMICs. This is the premise debated in this month's Point/Counterpoint.

Análisis de los riesgos asociados al uso de la técnica VMAT frente a 3DCRT en tratamientos de mama con cadenas ganglionares axilo-claviculares

et al. 2021

La utilización de arcoterapia volumétrica de intensidad modulada (VMAT) para el tratamiento de cáncer de mama siempre ha sido un asunto controvertido. La mayor conformación de las dosis absorbidas altas que se consigue con la VMAT frente a la radioterapia conformada (3DCRT) viene acompañada de un incremento del volumen irradiado con dosis absorbidas bajas, cuyas consecuencias hay que analizar. El presente estudio pretende, mediante el análisis de las dosimetrías clínicas de 80 pacientes con cáncer de mama tratadas en nuestro centro con ambas técnicas, evaluar la idoneidad de la elección de una técnica frente a la otra para el tratamiento de pacientes con cáncer de mama que precisan la irradiación de cadenas ganglionares axilo-claviculares, pero no de la cadena mamaria interna. Para ello se tienen en cuenta por un lado criterios puramente dosimétricos, como el cumplimiento de los límites de dosis absorbida establecidos en órganos de riesgo, y por otro se realiza una estimación del aumento en la probabilidad de desarrollar tumores secundarios sólidos por la irradiación a baja dosis de órganos sanos y se evalúan las posibles la toxicidades, cardiacas y pulmonares, en base a lo descrito en la literatura.
