5. Outcome of severe infections in afebrile neutropenic cancer patientsKsenija Strojnik, Ksenija Mahkovic Hergouth, Barbara Jezeršek Novaković, Boštjan Šeruga, 2016, original scientific article Abstract: In some neutropenic cancer patients fever may be absent despite microbiologically and/or clinically confirmed infection. We hypothesized that afebrile neutropenic cancer patients with severe infections have worse outcome as compared to cancer patients with febrile neutropenia. Patients and methods. We retrospectively analyzed all adult cancer patients with chemotherapy-induced neutropenia and severe infection, who were admitted to the Intensive Care Unit at our cancer center between 2000 and 2011. The outcome of interest was 30-day in-hospital mortality rate. Association between the febrile status and in-hospital mortality rate was evaluated by the Fishers exact test. Results. We identified 69 episodes of severe neutropenic infections in 65 cancer patients. Among these, 9 (13%) episodes were afebrile. Patients with afebrile neutropenic infection presented with hypotension, severe fatigue with inappetence, shaking chills, altered mental state or cough and all of them eventually deteriorated to severe sepsis or septic shock. Overall 30-day in-hospital mortality rate was 55.1%. Patients with afebrile neutropenic infection had% a trend for a higher 30-day in-hospital mortality rate as compared to patients with febrile neutropenic infection (78% vs. 52%, p = 0.17).

6. Dedni rak telesa maternice : kdaj je indicirano genetsko svetovanjeKsenija Strojnik, Ana Blatnik, Mateja Krajc, 2023, published scientific conference contribution Abstract: Tudi genetski dejavniki imajo vlogo pri nagnjenosti k razvoju raka telesa maternice. Najpogosteje se pojavlja v sklopu dednega sindroma Lynch (približno 3 % vseh bolnic z rakom telesa maternice). Pri vseh bolnicah s karcinomom endometrija se zato opravlja presejanje za sindrom Lynch, in sicer z imunohistokemičnim barvanjem za izražanje beljakovin popravljanja neujemanja in/ali z določanjem mikrosatelitne nestabilnosti iz primarnega tumorja. Pri vseh je tudi zelo pomembno natančno preveriti družinsko in osebno anamnezo drugih malignih ali benignih tumorjev. Na ta način aktivno iščemo tiste, ki imajo večjo verjetnost, da so nosilke genetskih okvar, povezanih z dedno obliko raka telesa maternice. Te potrebujejo napotitev in obravnavo pri kliničnem genetiku. V Ambulanti za onkološko genetsko svetovanje Onkološkega inštituta Ljubljana obravnava teh bolnic in njihovih svojcev poteka v okviru multidisciplinarne obravnave. Nosilci podedovanih genskih okvar lahko na podlagi genetskega izvida informirano soodločajo o preventivnih ukrepih glede na njihovo ogroženost za rake, ki so povezani v določen dedni sindrom.

8. Dedni dejavniki, povezani z rakom prostateMateja Krajc, Ana Blatnik, Ksenija Strojnik, 2023, published scientific conference contribution Abstract: Rak prostate je najpogostejši rak pri moških tako v svetu kot tudi v Sloveniji. Najpomembnejši nevarnostni dejavniki za raka prostate so starost, etnična pripadnost in družinska anamneza raka prostate. Rak prostate se lahko pojavlja v sklopu različnih dednih sindromov, kot sta npr. sindrom dednega raka dojk in/ ali jajčnikov in sindrom Lynch. Moških z rakom prostate in pozitivno družinsko anamnezo rakavih obolenj ne testiramo le zato, da bi ocenili njihovo ogroženost za razvoj drugih rakov v sklopu dednega sindroma. Zaradi razvoja specifičnih zdravil je izvid genetskega testiranja lahko pri njih pomemben tudi za načrtovanje zdravljenja. Zadnjih nekaj let smo priča hitremu razvoju genetskih testiranj za zarodne patogene in verjetno patogene različice v genih, ki visoko in zmerno ogrožajo za raka prostate in lahko napovedujejo agresivnost bolezni in odziv na specifično zdravljenje. Obenem se uveljavlja tudi genetsko testiranje vzorcev tumorske DNA, ki zazna tako zarodne kot pridobljene, t. i. somatske patogene različice, vpletene v proces kancerogeneze. Genetski izvid je pomemben tudi za krvne sorodnike testiranih. Če je v določenem genu prisotna zarodna patogena različica, je možno odkrivanje nosilcev te okvare tudi med ostalimi sorodniki. Zdravim nosilcem lahko tako omogočimo njim prilagojene presejalne programe za rake, za katere so lahko visoko ali zmerno ogroženi.

10. Identification of spliceogenic variants beyond canonical GT-AG splice sites in hereditary cancer genesVita Šetrajčič Dragoš, Ksenija Strojnik, Gašper Klančar, Petra Škerl, Vida Stegel, Ana Blatnik, Marta Banjac, Mateja Krajc, Srdjan Novaković, 2022, original scientific article Abstract: Pathogenic/likely pathogenic variants in susceptibility genes that interrupt RNA splicing are a well-documented mechanism of hereditary cancer syndromes development. However, if RNA studies are not performed, most of the variants beyond the canonical GT-AG splice site are characterized as variants of uncertain significance (VUS). To decrease the VUS burden, we have bioinformatically evaluated all novel VUS detected in 732 consecutive patients tested in the routine genetic counseling process. Twelve VUS that were predicted to cause splicing defects were selected for mRNA analysis. Here, we report a functional characterization of 12 variants located beyond the first two intronic nucleotides using RNAseq in APC, ATM, FH, LZTR1, MSH6, PALB2, RAD51C, and TP53 genes. Based on the analysis of mRNA, we have successfully reclassified 50% of investigated variants. 25% of variants were downgraded to likely benign, whereas 25% were upgraded to likely pathogenic leading to improved clinical management of the patient and the family members.
