6. Induction chemotherapy, chemoradiotherapy and consolidation chemotherapy in preoperative treatment of rectal cancer : long-term results of phase II OIGIT-01 TrialDanijela Golo, Jasna But-Hadžić, Franc Anderluh, Erik Brecelj, Ibrahim Edhemović, Ana Jeromen, Mirko Omejc, Irena Oblak, Ajra Šečerov Ermenc, Vaneja Velenik, 2018, original scientific article Abstract: The purpose of the study was to improve treatment efficacy for locally advanced rectal cancer (LARC) by shifting half of adjuvant chemotherapy preoperatively to one induction and two consolidation cycles. Patients and methods Between October 2011 and April 2013, 66 patients with LARC were treated with one induction chemotherapy cycle followed by chemoradiotherapy (CRT), two consolidation cycles, surgery and three adjuvant capecitabine cycles. Radiation doses were 50.4 Gy for T2-3 and 54 Gy for T4 tumours in 1.8 Gy daily fraction. The doses of concomitant and neo/adjuvant capecitabine were 825 mg/m2/12h and 1250mg/m2/12h, respectively. The primary endpoint was pathologic complete response (pCR). Results Forty-three (65.1%) patients were treated according to protocol. The compliance rates for induction, consolidation, and adjuvant chemotherapy were 98.5%, 93.8% and 87.3%, respectively. CRT was completed by 65/66 patients, with G % 3 non-hematologic toxicity at 13.6%. The rate of pCR (17.5%) was not increased, but N and the total-down staging rates were 77.7% and 79.3%, respectively. In a median follow-up of 55 months, we recorded one local relapse (LR) (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates were 64.0% (95% CI 63.89%64.11) and 69.5% (95% CI 69.39%69.61), respectively. Conclusions In LARC preoperative treatment intensification with capecitabine before and after radiotherapy is well tolerated, with a high compliance rate and acceptable toxicity. Though it does not improve the local effect, it achieves a high LR rate, DFS, and OS.

7. Health-related quality of life assessed by the EORTC QLQ-C30 questionnaire in the general Slovenian populationVaneja Velenik, Ajra Šečerov Ermenc, Jasna But-Hadžić, Vesna Zadnik, 2017, original scientific article Abstract: The aim of our study was to obtain reference data of the EORTC QLQ-C30 quality of life dimensions for the general Slovenian population. We intend to provide the researchers and clinicians in our country with the expected mean health-related quality of life (HRQL) scores for distinctive socio-demographic population groups. Methods. The EORTC QLQ-C30 questionnaire supplemented by a socio-demographic inquiry was mailed or distributed to 1,685 randomly selected individuals in the Slovenian population aged 18 % 90. Answers from 1,231 subjects representing socio-demographic diversity of the Slovenian population were collected and transformed into EORTC dimensions and symptoms. The impact of socio-demographic features on HRQL scores was assessed by multiple linear regression models. Results. Gender, age and self-rated social class are the important confounders in the quality of life scores in our population. Men reported better quality of life on the majority of the specific scales and, at the same time, reported fewer symptoms. There was no gender-specific difference in cognitive functioning. The mean scores were consistently lower with age in both sexes. Conclusions. This is the first study to report the normative EORTC QLQ-C30 scores for one of the south-eastern European populations. The reported expected mean scores allow Slovenian oncologists to estimate what the quality of life in cancer patients would be, had they not been ill. As they are derived by common methodology, our results can easily be included in any further international comparisons or in the calculation of European summarized HRQL scores.

8. The impact of anaemia on treatment outcome in patients with squamous cell carcinoma of anal canal and anal marginIrena Oblak, Monika Češnjevar, Mitja Anžič, Jasna But-Hadžić, Ajra Šečerov Ermenc, Franc Anderluh, Vaneja Velenik, Ana Jeromen, Peter Korošec, 2016, original scientific article Abstract: Radiochemotherapy is the main treatment for patients with squamous cell carcinoma of the anal canal. Anaemia is reported to have adverse effect on survival in cancer patients. The aim of the study was to evaluate the influence of anaemia on radiochemotherapy treatment outcome in patients with squamous cell carcinoma of the anal canal. Patients and methods. One hundred consecutive patients with histologically confirmed squamous cell carcinoma of the anal canal were treated radically with 3-dimensional conformal or intensity-modulated radiation therapy followed by brachytherapy or external beam radiotherapy boost and with concurrent mitomycin C and 5-fluorouracil. The influence on survival of pre-treatment, mean on-treatment and end-of-treatment haemoglobin (Hb) concentrations was studied. Results. The 5-year locoregional control, disease free survival, disease specific survival and overall survival rates for all patients were 72%, 71%, 77% and 62%, respectively. In univariate analysis, patients with pre-treatment and end-oftreatment Hb > 120 g/L survived statistically significantly better compared to patients with Hb % 120 g/L. Patients with mean on-treatment Hb > 120 g/L only had statistically significant better locoregional control and overall survival than patients with Hb % 120 g/L. In multivariate analysis, independent prognostic factors were pre-treatment Hb (> 120 g/L vs. % 120 g/L) for overall survival (hazard ratio [HR] = 0.419, 95% confidence interval [CI] = 0.190%0.927, p = 0.032) and stage (I & II vs. III) for disease specific (HR = 3.523, 95% CI = 1.375%9.026, p = 0.009) and overall survival (HR = 2.230, 95% CI = 1.167%4.264, p = 0.015). Conclusions. The pre-treatment, mean on-treatment and end-of-treatment Hb concentration > 120 g/L carried better prognosis for patients for with squamous cell carcinoma of the anal canal treated with radiochemotherapy. The pre-treatment Hb > 120 g/L was an independent prognostic factor for overall survival of patients with anal canal cancer.

9. 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, original scientific article Abstract: 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.

10. 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, professional article Abstract: 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.
