“…Our results showed that the prone group had greater total couchposition deviation (S) than the supine group (P=0.001); the deviation was apparent in the cranial-caudal (P=0.003) and ventral-dorsal (P=0.003) directions. Similarly, previous literature has also reported that the prone position decreases setup reproducibility, especially in the cranial-caudal and ventral-dorsal directions, and the belly board increases setup error (15)(16)(17)(18).…”

Background: To evaluate the influence of patient positioning on target dose coverage and dose distribution to the small bowel in intensity-modulated radiation therapy (IMRT) for rectal cancer patients.Methods: Twenty-four consecutive rectal cancer patients undergoing postoperative radiation were selected and set up in either a prone or supine position. All patients received computed tomography (CT) scans before and during treatment (1-4 weeks). The CT images were defined as plan, 1W, 2W, 3W, or 4W. The plan, 1W, 2W, 3W and 4W CT images were fused. The clinical target volume (CTV) and planning target volume (PTV) delineated on the plan CT were copied onto the 1-4W CT. The treatment plans based on the plan CT were also copied onto the 1-4W CT. The target dose coverage rate was assessed. The couchposition data of the linear accelerator were acquired.Results: Failure rates of the CTV and PTV target dose coverage were higher in the prone group than in the supine group (18.60% vs. 0% and 69.76% vs. 53.65%) during the treatment. The total couch-position deviation for the prone group (1.23±0.76 cm) was significantly greater than that of the supine group (0.28± 0.18 cm; P=0.001). Compared with the supine group, the prone group had significantly less irradiated small bowel volume at V5 (P=0.003) and V10 (P=0.004). Conclusions:The supine position maintained better target dose coverage and setup reproducibility in rectal cancer patients treated with IMRT. The prone position combined with the belly board can reduce the dose received by the small bowel.

“…It can be more useful to apply BBD (Belly Board device) for pelvic malignancies whenever the small bowel dose could be a restrictive factor for target dose escalation in clinical routine ( Estabrook et al, 2016 ). For lung cancer, the supine position is superior to prone orientation by mitigating the target margins ( Guy et al, 2020 ).…”

Treatment management of cancer patients in the radiation oncology departments during the current COVID-19 pandemic is challenging. A systematic review of published consensus/guidelines on the role of radiotherapy prioritization, suggested treatment protocols, and set up management was undertaken based on the PRISMA protocol and through PubMed/PMC, Scopus, Google Scholar, Web of Science databases until 01/20/2021. One hundred and sixty-eight publications or regional consensus were included. Summary of recommendations contained: (1) using hypo-fractionated (Hypo-F) regimens for therapeutic/palliative indications, (2) delaying radiotherapy for several weeks or until pandemic over, (3) omitting radiotherapy by replacement of alternative therapies or active surveillance, (4) applying safer patients' setup and preparation protocols, (5) developing telemedicine/telehealth service. To conclude, it is essential to carefully weigh the risk of exposure to COVID-19 infection and the benefit of treating cancer patients during the pandemic. Trying to have a global guideline facing this or any other probable crisis is crucial for health care service.

ApstraktCilj: prikazati metodologiju rada primjenom modernih tehnika zračenja. Pozadina: Tehnološki razvoj rezultirao je implementacijom novih tehnika zračenja i omogućio preciznu isporuku visokih doza zračenja na ciljni volumen uz maksimalnu poštedu okolnih zdravih tkiva. Metodologija: priprema pacijenta na 4DCT-simulatoru uz adekvatnu imobilizaciju, fuzija simulacione CT slike s dijagnostičkim CT/MRI/PET, delineacija volumena zračenja i zdravih organa. Planiranje zračenja provodi se prema VMAT/RapidArc: Eclipse TPS protokolu s ciljem eskalacije doze u targetu i maksimalnom poštedom zdravih tkiva strmim padom doze. To se postiže izocentričnom isporukom doze iz više sekvencijalnih malih snopova zračenja nejednakog intenziteta (IMRT) ili Arc-tehnikom iz izvora koji kruži oko pacijenta za 360 o , dok je volumen zračenja moduliran dinamičkim pomjeranjem listova kolimatora (VMAT SRS/SRT, SBRT). Preciznost isporuke doze provjerom pozicije targeta osigurava se slikovnim vođenjem radioterapije (IGRT) tokom isporuke doze (OBI CBCT). Diskusija: primjena modernih tehnika zračenja zahtijeva visokosofisticiranu opremu i educirano osoblje, što omogućava isporuku visokih doza zračenja na tumorsko tkivo. Pošteda zdravih tkiva je značajna u odnosu na ranije tehnike, ali istovremeno se malim dozama ozrači veći volumen zdravog tkiva. Zaključak: Isporuka visokih doza zračenja na tumorsko tkivo je u direktnoj korelaciji s boljom tumorskom kontrolom, uz doze na zdrava tkiva ispod granice doze koja ne dovodi do značajnijeg poremećaja funkcije (<5% komplikacija). Provođenje QA procedura u cilju kontrole visokih terapijskih doza na target i niskih doza na zdrava tkiva u cilju prevencije ranih i kasnih nusefekata.Ključne riječi: zaštita, zračenje, SRT/SBRT, IMRT.* Studija prikazana u članku provedena je u Affidea IMC Centru za radioterapiju Banja Luka
