The HERe2cure project, which involved a group of breast cancer experts, members of multidisciplinary tumor boards from healthcare institutions in Bosnia and Herzegovina, was initiated with the aim of defining an optimal approach to the diagnosis and treatment of HER2 positive breast cancer. After individual multidisciplinary consensus meetings were held in all oncology centers in Bosnia and Herzegovina, a final consensus meeting was held in order to reconcile the final conclusions discussed in individual meetings. Guidelines were adopted by consensus, based on the presentations and suggestions of experts, which were first discussed in a panel discussion and then agreed electronically between all the authors mentioned. The conclusions of the panel discussion represent the consensus of experts in the field of breast cancer diagnosis and treatment in Bosnia and Herzegovina. The objectives of the guidelines include the standardization, harmonization and optimization of the procedures for the diagnosis, treatment and monitoring of patients with HER2-positive breast cancer, all of which should lead to an improvement in the quality of health care of mentioned patients. The initial treatment plan for patients with HER2-positive breast cancer must be made by a multidisciplinary tumor board comprised of at least: a medical oncologist, a pathologist, a radiologist, a surgeon, and a radiation oncologist/radiotherapist.
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
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
