5. 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, original scientific article Abstract: 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.

6. Obsevanje benignih bolezniIvica Ratoša, Blaž Grošelj, Boris Jančar, Uroš Smrdel, Jasna But-Hadžić, Helena Barbara Zobec Logar, 2024, review article Abstract: 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.

7. 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, original scientific article Abstract: 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.

8. 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, original scientific article Abstract: 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.
