1. Breast cancer during pregnancy : retrospective institutional case seriesErika Matos, Tanja Ovčariček, 2021, izvirni znanstveni članek Povzetek: Pregnancy associated breast cancer is a rare disease. It presents a unique entity of breast cancer with aggressive phenotype. The main aim was to evaluate how the international guidelines were followed in daily practice. Patients and methods. Data concerning patients% and tumours% characteristics, management, delivery and ma-ternal outcome were recorded from institutional electronic database. In this paper a case series of pregnant breast cancer patients treated at single tertiary institution between 2007 and 2019 are presented and the key recommenda-tions on managing such patients are summarized.Results. Fourteen patients met the search criteria. The majority of tumours were high grade, triple negative or HER2 positive, two patients were de novo metastatic. Treatment plan was made for each patient by multidisciplinary team. Eight patients were treated with systemic chemotherapy with no excess toxicity or severe maternal/fetal adverse ef-fects. In all but two patients, delivery was on term and without major complications. Only one event, which was not in whole accordance with international guidelines, was identified. It was the use of blue dye in one patient.Conclusions. Women with pregnancy associated breast cancer should be managed like non-pregnant breast cancer patients and should expect a similar outcome, without causing harm to the unborn child. To achieve a good outcome in pregnancy associated breast cancer, a multidisciplinary approach is mandatory.

6. Triple negative breast cancer : prognostic factors and survivalTanja Ovčariček, Snježana Frković-Grazio, Erika Matos, Barbara Možina, Simona Borštnar, 2011, izvirni znanstveni članek Povzetek: Background. Triple negative breast cancer (TNBC) is defined by a lack of expression of both estrogen (ER) and progesteron(PgR) receptors as well as human epidermal growth factor receptor 2 (HER2). Our retrospective analysis addressed prognostic factors for short- and long-term outcomes of patients (pts) with TNBC pts treated in routine clinical practice. Patient and methods.Our retrospective study included 269 TNBC treated at Institute of Oncology Ljubljana between March 2000 and December 2006. The collected data included patientsć, tumoursć and treatmentsć characteristics. The survival analyses were performed using the Kaplan-Meier method. The Cox proportional hazard model was used in the multivariate analysis. Results. The median age ofour patients was 55.3 yrs (23-88.5) and the median follow-up was 5.9 yrs (0.3-9.6). Six (2%) pts experienced local only, 79 (92%) pts distal recurrenceand 66 (24%) died. The predominant localisation of the first relapsewas in visceral organs (70.4%). The 5-year disease-free survival (DFS) for the entire group was 68.2% and the 5-year overall survival (OS) was 74.5%.We found a pattern of high recurrence rate in the first 3 years following the diagnosis and a clear decline in recurrence rate over the next 3years. In the univariate analysis age, nodal status, size and lymphovascular invasion (LVI) were found to have a significant impact on DFS as well as on OS. In the multivariate analysis only age (HR=1.79; 95%CI=1.14-2.82; p=0.012) and nodal status (HR=2.71; 95%CI=1.64-4.46; p<0.001) retained their independent prognostic value for DFS and for OS only the nodal status (HR=2.96; 95%CI=1.51-5.82; p=0.002).

9. Nemetastatski, na kastracijo odporen rak prostateTanja Ovčariček, 2023, objavljeni znanstveni prispevek na konferenci Povzetek: Nemetastatski, na kastracijo odporen rak prostate (nKORP) je opredeljen kot porast vrednosti za prostato specifičnega antigena (PSA) po lokalnem zdravljenju ob kastracijski vrednosti testosterona, doseženi bodisi s kirurško ali medikamentozno odtegnitvijo androgenov ter brez dokazanih metastaz s konvencionalnimi radiološkimi metodami. Evropska in ameriška agencija za zdravila (EMA in FDA) sta na podlagi izsledkov treh randomiziranih kliničnih raziskav odobrili zdravljenje s kombinacijo antiandrogenov druge generacije (apalutamid, darolutamid, enzalutamid) in zdravljenje z odtegnitvijo androgenov za zdravljenje bolnikov z nKORP z visokim tveganjem za ponovitev bolezni. Bolniki z nKORP običajno nimajo simptomov maligne bolezni, po drugi strani pa gre pretežno za starejšo populacijo bolnikov s številnimi komorbidnostmi. Zato je v zdravljenju nKORP tehtanje med tveganjem in dobrobitjo kombiniranega sistemskega zdravljenja še posebej pomembno.
