<p>Uvod: Učestalost neželjenih efekata uzrokovanih zračenjem kod pacijenata sa karcinomom glave i vrata zavisi od tehnike planiranja, sprovođenja radioterapije kao i primarne lokalizacije tumora. Cilj: Osnovna uloga našeg istraživanja je da se utvrdi učestalost neželjenih efekata tokom zračne terapije kod pacijenata sa tumorom glave i vrata tretiranih 2D konvencionalnom radioterapijom, 3D konformalnom radioterapijom planiranoj samo na osnovu CT-a nasuprot 3D konformalnoj terapiji planiranoj na osnovu fuzije kompjuterizovane tomografije sa magnetno rezontnim imidžingom (CT-MRI). Metode: Prospektivno je analizirano 90 pacijenata sa karcinomom glave i vrata kod kojih je sprovedena zračna terapija. 30 pacijenata sa karcinomom glave i vrata je zračeno 2D konvencionalnom tehnikom, drugih 30 pacijenata je zračeno 3D konformalom tehnikom na osnovu CT-a, a preostalih 30 pacijenata sa fuzijom CT-MRI. Kod svih bolesnika je primenjena standardna frakcionacija sa 2 Gy dnevno, pet dana sedmično. Rezultati: Od ukupno 90 pacijenata lečenih primenom zračne terapije, kod 72 pacijenta (72/90; 64,8%) su zabeleženi neželjeni efekti zračne terapije a učestalost komplikacija je veća kod primene 2D tehnike zračenja (28/72; 38,9% for 2D RT vs 24/72; 33,3% for 3D CT RT vs 20/72; 27,8% for 3D CT-MRI; p=0,015). Zaključak: 3D tehnika radioterapije planirana samo na osnovu CT-a je povezana sa visokom stopom toksičnosti koje znatno utiču na kvalitet života zračenih pacijenata. 3D konformalna tehnika radioterapije planirana sa CT-MRI fuzijom smanjuje pojavu oralnih komplikacija. Slično razvijenim zemljama, trebalo bi razmotriti uvođenje ove tehnike kao standardnu metodu zračenja bolesnika sa tumorom glave i vrata. Za isporuku viših tumorskih doza uz manju učestalost komplikacija je podesnija tehnika planiranja sa fuzionisanom tehnikom pomoću MR imidžinga. 2D tehnika radioterapije glave i vrata se preporučuje samo za palijativne zračne tretmane.</p> / <p>Introduction: The incidence of radiation-induced side effects in patients with head and neck cancer (H&N) depends on technique of planning and the irradiation dose as well as primary tumor location within the H&N region. Objective: The aim of our research is to establish the incidence of side effects in patients with head and neck cancer treated with 2D- conventional radiotherapy, 3D-conformal radiotherapy planning with computed tomography (CT) or computed tomography fusion with magnetic resonance imaging (CT-MRI fusion). Methods: Prospective analysis was performed on 90 patients with head and neck carcinoma prospectively followed after radiotherapy. 30 patients with H&N cancer were irradiated by using 2D conventional radiotherapy, other 30 patients irradiated with 3D conformal radiotherapy planning with CT, while other 30 patients were treated using 3D conformal radiotherapy planning with CT-MRI fusion. In all cases standard fractionation was used at 2 Gy per day /5 days a week. Results: Of the total number (n=90) of treated patients, 72 patients (72/90; 64,8%) reported a side effect and the incidence of complications was higher in patients irradiated with 2D technique planning radiotherapy (28/72; 38,9% for 2D RT vs 24/72; 33,3% for 3D CT RT vs 20/72; 27,8% for 3D CT-MRI; p=0,015). Conclusion: 3D radiotherapy technique planned solely on the basis of CT is related to high incidence of toxicity which significantly affects the quality of life of irradiated patients. 3D conformal radiotherapy planned with CT-MRI fusion reduces the incidence of oral complications. Following the example of developed countries, this technique should be considered as a standard method for irradiating patients with head and neck cancer. Planning technique with fusion technique using MR imaging is more suitable for delivering higher doses to the tumor with fewer side effects. Recommendation 2D conventional radiotherapy is more for palliative treatments.</p>
