1. Do double-expressor high-grade B-cell lymphomas really need intensified treatment : a report from the real-life series of high-grade B-cell lymphomas treated with different therapeutic protocols at the Institute of Oncology LjubljanaLučka Boltežar, Samo Rožman, Gorana Gašljević, Biljana Grčar-Kuzmanov, Barbara Jezeršek Novaković, 2024, izvirni znanstveni članek Povzetek: High-grade B-cell lymphomas with MYC and BCL2 and/or BCL6 rearrangements are known for their aggressive clinical course and so are the ones with MYC and BCL2 protein overexpression. The optimal therapy for these lymphomas remains to be elucidated. A retrospective analysis of all diffuse large B-cell lymphomas and high-grade B-cell lymphomas with MYC and BCL2 and/or BCL6 rearrangements diagnosed between 2017 and 2021 at the Institute of Oncology Ljubljana, Slovenia, has been performed. Only patients with double-expressor lymphoma (DEL), double-hit lymphoma (DHL), or triple-hit lymphoma (THL) were included. Demographic and clinical parameters were assessed, as well as progression-free survival (PFS) and overall survival (OS). In total, 161 cases out of 309 (161/309; 52,1%) were classified as DEL. Sixteen patients had DHL, MYC/BCL2 rearrangement was observed in eleven patients, and MYC/BCL6 rearrangement was observed in five patients. Five patients were diagnosed with THL. Out of 154 patients (according to inclusion/exclusion criteria) included in further evaluation, one-hundred and thirty-five patients had double-expressor lymphoma (DEL), sixteen patients had DHL, and three patients had THL. In total, 169 patients were treated with R-CHOP, 10 with R-CHOP and intermediate-dose methotrexate, 19 with R-DA-EPOCH, and 16 with other regimens. The median follow-up was 22 months. The 5-year OS for the whole DEL group was 57.1% (95% CI 45.9–68.3%) and the 5-year PFS was 76.5% (95% CI 72.6–80.4%). The log-rank test disclosed no differences in survival between treatment groups (p = 0.712) while the high-risk international prognostic index (IPI) carried a significantly higher risk of death (HR 7.68, 95% CI 2.32–25.49, p = 0.001). The 5-year OS for DHL patients was 32.4% (95% CI 16.6–48.2%) while all three TH patients were deceased or lost to follow-up. Our analyses of real-life data disclose that the R-CHOP protocol with CNS prophylaxis is a successful and curative treatment for a substantial proportion of DEL patients.

2. Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) in breast cancer : correlation with traditional prognostic factorsMaja Lampelj, Darja Arko, Nina Čas-Sikošek, Rajko Kavalar, Maja Ravnik, Barbara Jezeršek Novaković, Sarah Dobnik, Nina Fokter Dovnik, Iztok Takač, 2015, izvirni znanstveni članek Povzetek: Background. Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) play a key role in tumour invasion and metastasis. High levels of both proteolytic enzymes are associated with poor prognosis in breast cancer patients. The purpose of this study was to evaluate the correlation between traditional prognostic factors and uPA and PAI-1 expression in primary tumour of breast cancer patients. Patients and methods. 606 primary breast cancer patients were enrolled in the prospective study in the Department of gynaecological oncology and breast oncology at the University Medical Centre Maribor between the years 2004 and 2010. We evaluated the traditional prognostic factors (age, menopausal status, tumour size, pathohistological type, histologic grade, lymph node status, lymphovascular invasion and hormone receptor status), together with uPA and PAI-1. We used Spearman%s rank correlation, Mann Whitney U test and X2 test for statistical analysis. Results. Our findings indicate a positive correlation between uPA and tumour size (p < 0.001), grade (p < 0.001), histological type (p < 0.001), lymphovascular invasion (p = 0.01) and a negative correlation between uPA and hormone receptor status (p < 0.001). They also indicate a positive correlation between PAI-1 and tumour size (p = 0.004), grade (p < 0.001), pathohistological type (p < 0.001) and negative correlation between PAI-1 and hormone receptor status (p = 0.002). Conclusions. Our study showed a relationship between uPA and PAI-1 and traditional prognostic factors. Their role as prognostic and predictive factors remains to be further evaluated.

3. The influence of folate pathway polymorphisms on high-dose methotrexaterelated toxicity and survival in children with non-Hodgkin malignant lymphomaNina Erčulj, Barbara Faganel Kotnik, Maruša Debeljak, Janez Jazbec, Vita Dolžan, 2014, izvirni znanstveni članek Povzetek: Background. We evaluated the influence of folate pathway polymorphisms on high-dose methotrexate (HD-MTX) related toxicity in paediatric patients with T-cell non-Hodgkin lymphoma (NHL). Patients and methods. In total, 30 NHL patients were genotyped for selected folate pathway polymorphisms. Results. Carriers of at least one MTHFR 677T allele had significantly higher MTX area under the time-concentration curve levels at third MTX cycle (P = 0.003). These patients were also at higher odds of leucopoenia (P = 0.006) or thrombocytopenia (P = 0.041) and had higher number of different HD-MTX-related toxicity (P = 0.035) compared to patients with wild-type genotype. Conclusions. Our results suggest an important role of MTHFR 677C>T polymorphism in the development of HD-MTXrelated toxicity in children with NHL.

4. MRI-assisted cervix cancer brachytherapy pre-planning, based on application in paracervical anaesthesia : final reportPrimož Petrič, Robert Hudej, Omar Hanuna, Primož Marolt, Barbara Šegedin, 2014, izvirni znanstveni članek Povzetek: Background. Optimal applicator insertion is a precondition for the success of cervix cancer brachytherapy (BT). We aimed to assess feasibility and efficacy of MRI-assisted pre-planning, based on applicator insertion in para-cervical anaesthesia (PCA). Patients and methods. Five days prior to BT, the pre-planning procedure was performed in 18 cervix cancer patients: tandem-ring applicator was inserted under PCA, pelvic MRI obtained and applicator removed. Procedure tolerability was assessed. High risk clinical target volume (HR CTV) and organs at risk were delineated on the pre-planning MRI, virtual needles placed at optimal positions, and dose planning performed. At BT, insertion was carried out in subarachnoidal anaesthesia according to pre-planned geometry. Pre-planned and actual treatment parameters were compared. Results. Pre-planning procedure was well tolerated. Median difference between the pre-planned and actual needle insertion depth and position were 2 (0%10) mm and 4 (0%30) degrees, respectively. The differences between the pre-planned and actual geometric and dosimetric parameters were statistically non-significant. All actual needles were positioned inside the HR CTV and outside the organs at risk (OAR). Conclusions. Our pre-planning approach is well tolerated and effective. Pre-planned geometry and dose distribution can be reproduced at BT.

5. Clonality analysis of lymphoid proliferations using the BIOMED-2 clonality assays : a single institution experienceIra Koković, Barbara Jezeršek Novaković, Petra Škerl, Srdjan Novaković, 2014, izvirni znanstveni članek Povzetek: Background. Clonality determination in patients with lymphoproliferative disorders can improve the final diagnosis.The aim of our study was to evaluate the applicative value of standardized BIOMED-2 gene clonality assay protocolsfor the analysis of clonality of lymphocytes in a group of different lymphoid proliferations.Materials and methods. With this purpose, 121 specimens from 91 patients with suspected lymphoproliferationssubmitted for routine diagnostics from January to December 2011 were retrospectively analyzed. According to thefinal diagnosis, our series comprised 32 cases of B-cell lymphomas, 38 cases of non-Hodgkins T-cell lymphomas and51 cases of reactive lymphoid proliferations. Clonality testing was performed using the BIOMED-2 clonality assays.Results. The determined sensitivity of the TCR assay was 91.9%, while the sensitivity of the IGH assay was 74.2%. Thedetermined specificity of the IGH assay was 73.3% in the group of lymphomas and 87.2% in the group of reactivelesions. The determined specificity of the TCR assay was 62.5% in the group of lymphomas and 54.3% in the group ofreactive lesions.Conclusions. In the present study, we confirmed the utility of standardized BIOMED-2 clonality assays for the detectionof clonality in a routine diagnostical setting of non-Hodgkins lymphomas. Reactions for the detection of thecomplete IGH rearrangements and reactions for the detection of the TCR rearrangements are a good choice forclonality testing of a wide range of lymphoid proliferations and specimen types while the reactions for the detectionof incomplete IGH rearrangements have not shown any additional diagnostic value.

7. What about the family? : The well-being of migrant children in comparative perspectiveZorana Medarić, Barbara Gornik, 2024, izvirni znanstveni članek Povzetek: This article explores the subjective perceptions of well-being of migrant children attending primary school (9-14 years) and secondary school (15-18 years) in Slovenia. It focuses on how they conceptualise their fears, worries and concerns, what is important for them to feel accepted and safe, and how they think about their past and the future. Using a comparative perspective, similarities and differences in the experience of well-being of these two age groups of migrants are explored. The analysis is based on open-ended narrative interviews with migrant children and revolves around the question of whether and how age influences their subjective perception of well-being. The article sheds light on age-specific meanings and understandings of migration processes based on the views and experiences of migrant children and youth regarding their well-being, bringing to the fore the perspectives of children that are often missing or underrepresented in integration policy.
