58. Safety and efficacy of drug-eluting microspheres chemoembolization under cone beam computed tomography control in patients with early and intermediate stage hepatocellular carcinomaŠpela Koršič, Nastja Levašič, Rok Dežman, Lara Anja Lešnik Zupan, Blaž Trotovšek, Rado Janša, Lojze Šmid, Peter Popović, 2022, izvirni znanstveni članek Povzetek: Background. Drug-eluting microsphere transarterial chemoembolization (DEM-TACE) is the standard of care in pa-tients with intermediate-stage hepatocellular carcinoma and ensures targeted and controlled cytotoxic and ischemic effects. Proper patient selection and optimized treatment techniques are associated with longer median survival. The aim of this single-institution retrospective study was to evaluate safety and efficacy of DEM-TACE under cone beam computed tomography (CBCT) control in patients with early and intermediate stagehepatocellular carcinoma.Patients and methods. A total of144 patients (mean age 67.9 ± 8.0 years, 127 males and 17 females) between February 2010 and December 2018 were studied. Microparticles of different dimensions according to two manufac-turers (diameter of 70–150 μm, 100–300 μm or 300–500 μm and 40-μm, 75-μm or 100-μm) were used and loaded with 50–150 mg of doxorubicin. The objective tumour response according to the modified Response Evaluation Criteria in Solid Tumours (mRECIST), the time to progression, adverse events and overall survival were (OS) evaluated.Results. In total, 452 procedures were performed (median, 3 per patient). Four (0.9% of all procedures) major com-plications were noted. Postembolization syndrome occurred after 35% of procedures. At the first imaging follow-up 2–3 months after first treatment, 91% of patients achieved an objective response. The median time to progression was 10.2 months (95% CI: 8.3-12.1 months). OS rates at 1, 2, 3, 4, and 5 years were 85%, 53%, 33%, 20% and 14%, respectively. The median survival time was 25.8 months (95% CI: 22.1–29.5 months). Conclusions. DEM-TACE under CBCT control in patients with early and intermediate stagehepatocellular carcinoma is a safe and effective method of treatment with high objective tumour response and survival rates.

59. Crystalloids vs. colloids for fluid optimization in patients undergoing brain tumour surgeryJasmina Markovič Božič, Božidar Visočnik, Polona Mušič, Iztok Potočnik, Alenka Spindler-Vesel, 2022, izvirni znanstveni članek Povzetek: Background. This randomised, double-blinded, single-centre study prospectively investigated the impact of goal directed therapy and fluid optimization with crystalloids or colloids on perioperative complications in patients un-dergoing brain tumour surgery. Main aim of the study was to investigate the impact of fluid type on postoperative complications.Patients and methods. 80 patients were allocated into two equal groups to be optimised with either crystalloids (n = 40) or colloids (n = 40). Invasive hemodynamic monitoring was used to adjust and maintain mean arterial pressure and cerebral oxygenation within the baseline values (± 20%) and stroke volume variation (SVV) ≤ 10%. Postoperative complications from different organ systems were monitored during the first 15 days after surgery. Hospital stay was also recorded.Results. Crystalloid group received significantly more fluids (p = 0.003) and phenylephrine (p = 0.02) compared to colloid group. This did not have any significant impact on perioperative complications and hospital stay, since no dif-ferences between groups were observed. Conclusions. Either crystalloids or colloids could be used for fluid optimization in brain tumour surgery. If protocol-ised perioperative haemodynamic management is used, the type of fluid does not have significant impact on the outcome.
