801. Care of patients with non-small-cell lung cancer stage III : the Central European real-world experienceMilada Zemanova, Robert Pirker, Luboš Petruželka, Zuzana Zbozínkova, Mirjana Rajer, Krisztina Bogos, Gunta Purkalne, Vesna Ceriman, Subhash Chaudhary, Igor Richter, 2020, izvirni znanstveni članek Povzetek: Background. Management of non-small-cell lung cancer (NSCLC) is affected by regional specificities. The present study aimed at determining diagnostic and therapeutic procedures including outcome of patients with NSCLC stage III in the realworld setting in Central European countries to define areas for improvements. Patients and methods. This multicentre, prospective and non-interventional study collected data of patients with NSCLC stage III in a web-based registry and analysed them centrally. Results. Between March 2014 and March 2017, patients (n=583) with the following characteristics were entered: 32% females, 7% never-smokers; ECOG performance status (PS) 0, 1, 2 and 3 in 25%, 58%, 12% and 5%, respectively; 21% prior weight loss; 53% squamous carcinoma, 38% adenocarcinoma; 10% EGFR mutations. Staging procedures included chest X-ray (97% of patients), chest CT (96%), PET-CT (27%), brain imaging (20%), bronchoscopy (89%), endobronchial ultrasound (EBUS) (13%) and CT-guided biopsy (9%). Stages IIIA/IIIB were diagnosed in 55%/45% of patients, respectively. N2/N3 nodes were diagnosed in 60%/23% and pathologically confirmed in 29% of patients. Most patients (56%) were treated by combined modalities. Surgery plus chemotherapy was administered to 20%, definitive chemoradiotherapy to 34%, chemotherapy only to 26%, radiotherapy only to 12% and best supportive care (BSC) to 5% of patients. Median survival and progression-free survival times were 16.8 (15.3;18.5) and 11.2 (10.2;12.2) months, respectively. Stage IIIA, female gender, no weight loss, pathological mediastinal lymph node verification, surgery and combined modality therapy were associated with longer survival. Conclusions. The real-world study demonstrated a broad heterogeneity in the management o f stage III NSCLC in Central European countries and suggested to increase the rates of PET-CT imaging, brain imaging and invasive mediastinal staging.

803. Percutaneous image guided electrochemotherapy of hepatocellular carcinoma : technological advancementMihajlo Djokić, Rok Dežman, Maja Čemažar, Miha Štabuc, Miha Petrič, Lojze Šmid, Rado Janša, Boštjan Plešnik, Maša Omerzel, Urša Lampreht Tratar, Blaž Trotovšek, Bor Kos, Damijan Miklavčič, Gregor Serša, Peter Popović, 2020, izvirni znanstveni članek Povzetek: Background. Electrochemotherapy is an effective treatment of colorectal liver metastases and hepatocellular carcinoma (HCC) during open surgery. The minimally invasive percutaneous approach of electrochemotherapy has already been performed but not on HCC. The aim of this study was to demonstrate the feasibility, safety and effectiveness of electrochemotherapy with percutaneous approach on HCC. Patient and methods. The patient had undergone the transarterial chemoembolization and microwave ablation of multifocal HCC in segments III, V and VI. In follow-up a new lesion was identified in segment III, and recognized by multidisciplinary team to be suitable for minimally invasive percutaneous electrochemotherapy. The treatment was performed with long needle electrodes inserted by the aid of image guidance. Results. The insertion of electrodes was feasible, and the treatment proved safe and effective, as demonstrated by control magnetic resonance imaging. Conclusions. Minimally invasive, image guided percutaneous electrochemotherapy is feasible, safe and effective in treatment of HCC.

804. Sorafenib for the treatment of hepatocellular carcinoma : a single-centre real-world studyJurij Hanžel, Tajda Božič, Borut Štabuc, Rado Janša, 2020, izvirni znanstveni članek Povzetek: Background Sorafenib is an oral multi-kinase inhibitor used for the treatment of hepatocellular carcinoma. Its efficacy in randomised controlled trials was demonstrated in patients with well-preserved liver function and good functional status. In the real-world setting, treatment is often offered to patients outside these criteria. We therefore performed a single-centre real-world cohort study on the efficacy of sorafenib in patients with hepatocellular carcinoma. Patients and methods We identified all patients with hepatocellular carcinoma initiating treatment with sorafenib between January 2015 and January 2018. The primary endpoint was overall survival (OS) since starting sorafenib. Clinical and demographic variables associated with survival were studied. Results The median OS was 13.4 months (95% CI 8.2%18.6). Multivariable Cox%s regression identified worse ECOG performance status (HR 2.21; 95% CI 1.56%3.16; P < 0.0001), Child-Pugh class C (HR 52.4; 95% CI 3.20%859; P = 0.005) and absence of prior locoregional treatment (HR 2.30; 95% CI 1.37%3.86; P = 0.002) to be associated with increased mortality. Conclusions Careful selection of patients for treatment with sorafenib is of paramount importance to optimize outcomes.

805. Diagnostic accuracy of (1-3)-[beta]-D-glucan to predict Pneumocystis jirovecii pneumonia in non-HIV-infected patientsPetra Rogina, Miha Skvarč, 2020, izvirni znanstveni članek Povzetek: Background Pneumocystis jirovecii pneumonia (PCP) is a common and potentially fatal opportunistic infection in immunocompromised non-HIV individuals. There are problems with clinical and diagnostic protocols for PCP that lack sensitivity and specificity. We designed a retrospective study to compared several methods that were used in diagnostics of PCP. Patients and methods One hundred and eight immunocompromised individuals with typical clinical picture for PCP and suspicious radiological findings were included in the study. Serum samples were taken to measure the values of (1-3)-[beta]-D-glucan (Fungitell, Associates of Cape Cod, USA). Lower respiratory tract samples were obtained to perform direct immunofluorescence (DIF, MERIFLUOR Pneumocystis, Meridian, USA) stain and real-time PCR (qPCR). Results Fifty-four (50%) of the 108 patients in our study had (1-3)-[beta]-D-glucan > 500 pg/ml. Patients that had (1-3)-[beta]-D-glucan concentrations < 400 pg/ml in serum, had mean threshold cycles (Ct) 35.43 +- 3.32 versus those that had (1-3)-[beta]-D-glucan concentrations >400 pg/mL and mean Ct of 28.97 +- 5.27 (P < 0.001). If we detected P. jirovecii with DIF and qPCR than PCP was proven. If the concentration of (1-3)-[beta]-D-glucan was higher than 400 pg/ml and Ct of qPCR was below 28.97 +- 5.27 than we have been able be certain that P. jirovecii caused pneumonia (odds ratio [OR] 2.31, 95% confidence interval [CI] 1.62-3.27, P < 0.001). Conclusions Measurement of (1-3)-[beta]-D-glucan or qPCR alone could not be used to diagnose PCP. Diagnostic cut-off value for (1-3)-[beta]-D-glucan > 400pg/ml and qPCR below 30 Ct, allow us to conclude that patient has PCP. If the values of (1-3)-[beta]-D-glucan are < 400 pg/ml and qPCR is above 35 Ct than colonization with P. jirovecii is more possible than PCP.

806. Mechanical recanalization for acute bilateral cerebral artery occlusion - literature overview with a caseMiran Jeromel, Zoran Miloševič, Janja Pretnar-Oblak, 2020, pregledni znanstveni članek Povzetek: Background. Acute bilateral internal carotid artery (ICA) and/or middle cerebral artery (MCA) occlusion is extremely rare and associated with poor clinical outcomes. There are only a few reports in the literature about mechanical thrombectomy being performed for acute bilateral occlusions. The treatment strategies and prognoses (clinical outcomes) are therefore unclear. Methods. A systematic review of the literature was performed through several electronic databases with the following search terms: acute bilateral stroke, mechanical recanalization and thrombectomy. Results. In the literature, we identified five reports of six patients with bilateral ICA and/or MCA occlusion treated with mechanical recanalization. Additionally, we report our experience with a subsequent contralateral large brain artery occlusion during intravenous thrombolytic therapy, where the outcome after mechanical thrombectomy was not dependent on the time from stroke onset but rather on the capacity of collateral circulation exclusively. Conclusions. Acute bilateral cerebral (ICA and/or MCA) occlusion leads to sudden severe neurological deficits (comas) with unpredicted prognoses, even when mechanical recanalization is available. As the collateral capacity seems to be more important than the absolute time to flow restoration in determining the outcomes, simultaneous thrombectomy by itself probably does not lead to improved functional outcomes.

807. Studying cell death initiation using a digital microscopeTina Arnšek, Nuša Golob, Nastja Marondini, Maruša Pompe Novak, Kristina Gruden, Tjaša Lukan, 2023, izvirni znanstveni članek Povzetek: Hypersensitive response (HR)-conferred resistance is an effective defense response that can be determined by the N resistance genes. HR is manifested as the formation of cell death zones on inoculated leaves. Here, a protocol for studying the rate of cell death initiation by imaging inoculated leaves in the time between the cell death initiation and the cell death appearance using a digital microscope is presented. The digital microscope enables a continuous imaging process in desired intervals, which allows an accurate determination of cell death initiation rate up to minutes exactly, as opposed to hours in traditional methods. Imaging with the digital microscope is also independent of light and can therefore be used during day and night without disturbing the circadian rhythm of the plant. Different pathosystems resulting in programmed cell death development could be studied using this protocol with minor modifications. Overall, the protocol thus allows simple, accurate, and inexpensive identification of cell death initiation rate.

810. The prevalence of occult ovarian cancer in the series of 155 consequently operated high risk asymptomatic patients : Slovenian population based studyAndreja Gornjec, Sebastjan Merlo, Srdjan Novaković, Vida Stegel, Barbara Gazić, Andraž Perhavec, Ana Blatnik, Mateja Krajc, 2020, izvirni znanstveni članek Povzetek: We assessed the prevalence, localization, type and outcome of occult cancer at risk-reducing salpingo-oophorectomy or salpingectomy (RRSO) in asymptomatic carriers of pathogenic or likely pathogenic BRCA1/2 variants and high-risk BRCA1/2 negative women. Patients and methods. A retrospective analysis of all consecutive gynaecologic preventive surgeries from January 2009 to December 2015 was performed. Participants underwent genetic counselling and BRCA1/2 testing before the procedure. Data on clinical parameters, adjuvant treatment and follow-up were collected and analysed. Results. One hundred and fifty-five RRSO were performed in 110 BRCA1, 35 BRCA2 carriers of pathogenic or likely pathogenic variants and 10 high-risk BRCA1/2 negative women, at the mean age of 48.3 years. Nine occult cancers (9/155, 5.8%) were identified; eight in BRCA1 positive women and one in high-risk BRCA1/2 negative woman. We identified four non-invasive serous intraepithelial tubal carcinomas (3 in BRCA1 carriers and 1 in a high-risk BRCA1/2 negative woman) and five invasive tubo-ovarian high grade serous cancers (all detected in BRCA1 carriers). Only one out of nine patients (11.1%) with occult cancer had a slightly elevated CA-125 value preoperatively. Conclusions. A 5.8% prevalence of occult invasive and noninvasive tubo-ovarian serous cancer after RRSO was found in high risk asymptomatic and screen negative women. We conclude that RRSO should be performed in BRCA1/2 carriers and in high-risk BRCA1/2 negative women. Age of preventive gynaecologic surgery should be carefully planned, taking into account the completion of childbearing age and type of mutation. The results favour the tubal hypothesis of tubal origin of high grade serous ovarian and peritoneal cancer. Cytology result of peritoneal cavity washing was important for the decision making process in determining treatment. Cytology examination should be performed in all cases of RRSO. CA-125 assay did not prove to be an effective screening tool for early cancer detection in our patients.
