1. Ocena finančnega bremena pri bolnikih z rakom v SlovenijiMarjeta Skubic, Katja Vöröš, Andraž Perhavec, Mojca Bavdaž, Petra Došenović Bonča, Tjaša Redek, Ivica Ratoša, Helena Barbara Zobec Logar, 2024, izvirni znanstveni članek Povzetek: Izhodišče: Finančna toksičnost (FT) predstavlja vse objektivne finančne posledice in subjektivne finančne skrbi, ki se pojavljajo pri bolnikih z rakom in njihovih svojcih zaradi bolezni in zdravljenja. Finančno breme, ki ga imajo slovenski bolniki z rakom, pred našo raziskavo še ni bilo opredeljeno, prav tako ni bil poznan vpliv FT na kakovost življenja (QoL).Namen: Cilj raziskave je bila ocena FT pri bolnikih z rakom v Sloveniji, njen vpliv na QoL bolnikov in preizkus dosedanjih inštrumentov za oceno FT in QoL.Metode: Za merjenje FT smo uporabili anketno metodologijo. Razvili smo lasten vprašalnik za oceno FT in uporabili mednaro-dno validirana vprašalnika FACIT-COST in EORTC QLQ-C30. Raziskava je bila prospektivna in presečna, potekala je na Onkolo-škem inštitutu Ljubljana od junija do oktobra 2023. Rezultati: Analizirali smo 590 veljavnih anket. Na podlagi vprašalnika FACIT-COST smo ugotovili, da večina anketiranih bolnikov (53,7 %) nima FT, pri 42,9 % anketiranih bolnikov pa je bila ta večinoma blaga do zmerna. Nizko FT med slovenski-mi bolniki z rakom smo potrdili tudi z vprašalnikom EORTC QLQ-C30 in lastnim vprašalnikom. Večina bolnikov (85,1 %) je ocenila, da zaradi bolezni in zdravljenja niso imeli večjih stroškov. Na podlagi kazalnika finančnega bremena FACIT-COST in EORTC QLQ-C30 smo ugotovili, da so rizične skupine za večjo FT predvsem bolniki z nižjim neto dohodkom na gospodinjstvo (p ≤0,001), mlajši bolniki (p < 0,001), bolniki z rakom dojk (p = 0,016), zaposleni (p < 0,001), pa tudi bolniki na aktivnem onkološkem zdravljenju (p = 0,039). Pri lastnem vprašalniku so se za statistično pomembne pokazali še nižja stopnja izobrazbe (p ≤ 0,001), pode-želsko okolje (p = 0,033) in vrsta zdravstvenega zavarovanja (p = 0,006). Vpliv veroizpovedi na FT na podlagi lastnega vprašalnika ni povezan z večjo FT, kot je to razvidno iz vprašalnikov FACI-T-COST in EORTC QLQ-C30. Potrdili smo tudi vpliv nižjega dohodka na slabšo QoL, ostali parametri, ki vplivajo na QoL, pa so še: zelo nizka ali zelo visoka stopnja izobrazbe, rak glave in vratu in aktivnost onkološkega zdravljenja.Zaključki: V Sloveniji večina bolnikov z rakom ne občuti FT, v 42,9 % pa je ta blaga do zmerna. FT je statistično značilno povezana z višino dohodka, starostjo, vrsto raka, zaposlitvenim statusom, aktivnostjo onkološkega zdravljenja, pa tudi s stopnjo izobrazbe, podeželskim okoljem in vrsto zdravstvenega zavarova-nja. Večja FT je povezana s slabšo QoL. Ta je povezana prav tako z višino dohodka, stopnjo izobrazbe, vrsto raka in aktivnostjo onkološkega zdravljenja.

2. Obsevanje benignih bolezniIvica Ratoša, Blaž Grošelj, Boris Jančar, Uroš Smrdel, Jasna But-Hadžić, Helena Barbara Zobec Logar, 2024, pregledni znanstveni članek Povzetek: Cilja zdravljenja z obsevanjem benignih bolezni sta povrnitev funkcije in izboljšanje kakovosti življenja. Obsevanje benignih bolezni se običajno izvaja z nizko dnevno in celokupno obsevalno dozo. V primerjavi z dozo, ki se jo uporablja za zdravljenje malignih obolenj, je doza tukaj navadno precej nižja. S sodobnimi obsevalni-mi tehnikami, ki se uporabljajo v radioterapiji v zadnjem desetletju, je tveganje za poškodbe zdravega tkiva majhno. Z natančnim načrtovanjem obsevanja se žarki usmerijo na prizadeto območje, kar omogoča ohranitev zdravih tkiv. Obsevanje je tako varno in učinkovito, a je treba kljub temu vedno oceniti, kdaj je dobrobit obsevanja večja od morebitnih neželenih učinkov.

3. Association between PIK3CA activating mutations and outcomes in early-stage invasive lobular breast carcinoma treated with adjuvant systemic therapyDomen Ribnikar, Valentina Jerič Horvat, Ivica Ratoša, Zachary Veitch, Biljana Grčar-Kuzmanov, Srdjan Novaković, Erik Langerholc, Eitan Amir, Boštjan Šeruga, 2023, izvirni znanstveni članek Povzetek: The aim of the study was to evaluate the independent prognostic role of PIK3CA activating mutationsand an association between PIK3CA activating mutations and efficacy of adjuvant endocrine therapy (ET) in patientswith operable invasive lobular carcinoma (ILC).Patients and methods.A single institution study of patients with early-stage ILC treated between 2003 and 2008 wasperformed. Clinicopathological parameters, systemic therapy exposure and outcomes (distant metastasis-free sur-vival [DMFS] and overall survival [OS]) were collected based on presence or absence of PIK3CA activating mutationin the primary tumor determined using a quantitative polymerase chain reaction (PCR)-based assay. An associationbetween PIK3CA mutation status and prognosis in all patient cohort was analyzed by Kaplan-Meier survival analysis,whereas an association between PIK3CA mutation and ET was analyzed in estrogen receptors (ER) and/or progester-one receptors (PR)-positive group of our patients by the Cox proportional hazards model.Results. Median age at diagnosis of all patients was 62.8 years and median follow-up time was 10.8 years. Among365 patients, PIK3CA activating mutations were identified in 45%. PIK3CA activating mutations were not associatedwith differential DMFS and OS (p = 0.36 and p = 0.42, respectively). In patients with PIK3CA mutation each year oftamoxifen (TAM) or aromatase inhibitor (AI) decreased the risk of death by 27% and 21% in comparison to no ET, re-spectively. The type and duration of ET did not have significant impact on DMFS, however longer duration of ET hada favourable impact on OS.Conclusions. PIK3CA activating mutations are not associated with an impact on DMFS and OS in early-stage ILC.Patients with PIK3CA mutation had a statistically significantly decreased risk of death irrespective of whether theyreceived TAM or an AI.

4. Breast size and dose to cardiac substructures in adjuvant three-dimensional conformal radiotherapy compared to tangential intensity modulated radiotherapyIvica Ratoša, Aljaša Jenko, Željko Šljivić, Maja Pirnat, Irena Oblak, 2020, izvirni znanstveni članek Povzetek: The aim of the study was to quantify planned doses to the heart and specific cardiac substructures in free-breathing adjuvant three-dimensional radiation therapy (3D-CRT) and tangential intensity modulated radiotherapy (t-IMRT) for left-sided node-negative breast cancer, and to assess the differences in planned doses to organs at risk according to patients% individual anatomy, including breast volume. Patients and methods. In the study, the whole heart and cardiac substructures were delineated for 60 patients using cardiac atlas. For each patient, 3D-CRT and t-IMRT plans were generated. The prescribed dose was 42.72 Gy in 16 fractions. Patients were divided into groups with small, medium, and large clinical target volume (CTV). Calculated dose distributions were compared amongst the two techniques and the three different groups of CTV. Results. Mean absorbed dose to the whole heart (MWHD) (1.9 vs. 2.1 Gy, P < 0.005), left anterior descending coronary artery mean dose (8.2 vs. 8.4 Gy, P < 0.005) and left ventricle (LV) mean dose (3.0 vs. 3.2, P < 0.005) were all significantly lower with 3D-CRT technique compared to t-IMRT. Apical (8.5 vs. 9.0, P < 0.005) and anterior LV walls (5.0 vs. 5.4 Gy, P < 0.005) received the highest mean dose (Dmean). MWHD and LV-Dmean increased with increasing CTV size regardless of the technique. Low MWHD values (< 2.5 Gy) were achieved in 44 (73.3%) and 41 (68.3%) patients for 3D-CRT and t-IMRT techniques, correspondingly. Conclusions. Our study confirms a considerable range of the planned doses within the heart for adjuvant 3D-CRT or t-IMRT in node-negative breast cancer. We observed differences in heart dosimetric metrics between the three groups of CTV size, regardless of the radiotherapy planning technique.

7. Preoperative treatment with radiochemotherapy for locally advanced gastroesophageal junction cancer and unresectable locally advanced gastric cancerIvica Ratoša, Irena Oblak, Franc Anderluh, Vaneja Velenik, Jasna But-Hadžić, Ajra Šečerov Ermenc, Ana Jeromen, 2015, izvirni znanstveni članek Povzetek: To purpose of the study was to analyze the results of preoperative radiochemotherapy in patients with unresectable gastric or locoregionally advanced gastroesophageal junction (GEJ) cancer treated at a single institution. Between 1/2004 and 6/2012, 90 patients with locoregionally advanced GEJ or unresectable gastric cancer were treated with preoperative radiochemotherapy at the Institute of Oncology Ljubljana. Planned treatment schedule consisted of induction chemotherapy with 5-fluorouracil and cisplatin, followed by concomitant radiochemotherapy four weeks later. Three-dimensional conformal external beam radiotherapy was delivered by dual energy (6 and 15 MV) linear accelerator in 25 daily fractions of 1.8 Gy in 5 weeks with two additional cycles of chemotherapy repeated every 28 days. Surgery was performed 4-6 weeks after completing radiochemotherapy. Following the surgery, multidisciplinary advisory team reassessed patients for the need of adjuvant chemotherapy. The primary endpoints were histopathological R0 resection rate and pathological response rate. The secondary endpoints were toxicity of preoperative radiochemotherapy and survival. Treatment with preoperative radiochemotherapy was completed according to the protocol in 84 of 90 patients (93.3%). Twenty patients (22.2%) did not undergo the surgery because of the disease progression, serious comorbidity, poor performance status or still unresectable tumour. In 13 patients (14.4%) only exploration was performed because the tumour was assessed as unresectable or diffuse peritoneal carcinomatosis was established. Fifty-seven patients (63.4%) underwent surgery with the aim of complete removal of the tumour. Radical resection was achieved in 50 (55.6%) patients and the remaining seven (7.8%) patients underwent non-radical surgery (R1 in five and R2 in two patients). In this group of patients (n = 57), pathological complete response of tumour was achieved in five patients (5.6% of all treated patients or 8.8% of all operated patients). Down-staging was recorded in 49 patients (86%), in one patient (1.8%) the stage after radiochemotherapy was unchanged while in seven patients (12.3%) the pathological stage was higher than clinical, mainly due to higher pN stage. No death was recorded during preoperative radiochemotherapy. Most grade 3 and 4 toxicities were due to vomiting, nausea and bone marrow suppression (granulocytopenia). Twentysix (45.6%) patients died due to GEJ or gastric carcinoma, one died because of septic shock following the surgery and a reason for two deaths was unknown. Twenty-eight patients (49.1%) were disease free at the time of analysis, while 29 patients (50.9%) developed the recurrence, mostly as distant metastases. At two years, locoregional control, diseasefree survival, disease-specific survival and overall survival were 82.9%, 43.9%, 56.9% and 53.9%, respectively. Preoperative radiochemotherapy was feasible in our group of patients and had acceptable toxicity. Majority of patients achieved down-staging, allowing greater proportion of radical resections (R0), which are essential for patientsʼ cure.

9. Stereotaktična radioterapija za zdravljenje refraktarne prekatne tahikardije: prikaz primerovTamara Jarm, Krištof Knap, Bor Antolič, Boštjan Berlot, Rihard Hudej, Aljaša Jenko, Ajra Šečerov Ermenc, Jasna But-Hadžić, Ivica Ratoša, 2023, strokovni članek Povzetek: Stereotaktična radioterapija aritmij (STAR) predstavlja novo in obetavno možnost za bolnike z refraktarno prekatno tahikardijo, ki je odporna proti konvencionalnim metodam zdravljenja. STAR omogoča natančno neinvazivno ablacijo aritmogenega substrata ob minimalni prizadetosti sosednjih organov. Ta metoda zdravljenja je uporabna za bolnike, pri katerih je tarčno tkivo s katetrsko ablacijo nedosegljivo, pogosti šoki implantabilnega kardioverter-defibrilatorja pa močno nižajo njihovo kakovost življenja ali kadar sta ti metodi zdravljenja zaradi slabega zdravstvenega stanja kontraindicirani. Tarčo obsevanja (predel levega prekata) natančno opredelimo s predhodno slikovno diagnostiko, elektrokardiogramom, posnetki prekatne tahikardije in po potrebi invazivnim ali neinvazivnim elektrofiziološkim mapiranjem srca. Po pripravi na obsevanje na simulatorju sledi enkratno obsevanje z visokim odmerkom 25 Gy, ki je trenutno edina standardna frakcionacija. Bolniki obsevanje dobro prenašajo. Dosedanje raziskave so poročale o dobri učinkovitosti zdravljenja z bistvenim zmanjšanjem pogostosti epizod prekatne tahikardije in brez večjih neželenih učinkov. Poročamo o prvi skupini štirih bolnikov z visokorizično refraktarno prekatno tahikardijo, ki so bili zdravljeni s stereotaktično radioterapijo na Onkološkem inštitutu Ljubljana. Izvedba STAR se je izkazala kot učinkovita metoda z nizko stopnjo akutnih neželenih učinkov in predstavlja novo možnost obravnave te ranljive skupine bolnikov v slovenskem prostoru.

10. Protibolečinsko obsevanje kostnih zasevkovEva Pribožič, Ivica Ratoša, Jasna But-Hadžić, 2023, drugi znanstveni članki Povzetek: Kostni zasevki povzročajo bolečino, ki vpliva na kakovost življenja bolnika in lahko vodijo do zapletov, ki zahtevajo urgentno ukrepanje. Ko zaradi kostnih zasevkov grozi oziroma je prisoten patološki zlom ali maligna kompresija hrbtenjače, je nujno oceniti, ali bolnik potrebuje kirurško intervencijo, ki ji sledi pooperativno obsevanje. Kadar bolnik ni kandidat za operativno zdravljenje, se priporoča urgentno obsevanje. Pri bolečih kostnih zasevkih, brez grozečega oziroma prisotnega patološkega zloma ali maligne utesnitve hrbtenjače, ne glede na velikost samega zasevka, prvi pristop zdravljenja bolečine predstavlja farmakološko zdravljenje, ki ga podpre in dopolni protibolečinsko paliativno obsevanje. Pri paliativnem obsevanju so celokupne obsevalne doze nizke, obsevanje je izvedeno v enem odmerku ali v kratkih obsevalnih režimih. Bolniki, ki ne odgovorijo na prvo obsevanje, ali se jim bolečina ponovi, so lahko varno ponovno obsevani na istem mestu. Na Onkološkem inštitutu Ljubljana smo opravili retrospektivni pregled paliativnih obsevanj kosti med leti 2018 – 2021. Letno obsevamo 800 kostnih zasevkov, upažamo pa upad števila obsevanj. Najpogostejša frakcionacija je 5 x 4 Gy, samo 10% bolnikov pa prejme obsevanje v enem odmerku. Protibolečinsko obsevanje kosti je učinkovito, stroškovno učinkovito in varno. Pomembno je prepoznati bolnike, ki bi imeli korist od protibolečinskega obsevanja, in jih napotiti na konzilij. S poenostavitvijo radioterapevtskih postopkov in odločitvijo za obsevanje v enem odmerku, je lahko obsevalno zdravljenje bolniku prijaznejše in dostopnejše.
