4. Rak neznanega izvora : nas izvor bolezni še zanimaErika Matos, Snežana Pavlović Djokić, Srdjan Novaković, Marina Čakš, Rok Devjak, Nežka Hribernik, Kaja Cankar, 2024, professional article Abstract: Rak neznanega izvora (RNI) je opredeljen kot karcinom ali nediferencirana neoplazma, pri kateri z naborom standardnih diagnostičnih postopkov ni mogoče odkriti izvornega mesta bolezni. Tradicionalno RNI delimo v dve podskupini, pri čemer le približno 15 % primerov predstavlja prognostično ugodno skupino. Velika večina bolnikov spada v prognostično neugodno skupino in ima ob prvi prezentaciji obsežno breme bolezni. Možnosti zdravljenja so omejene, izidi bolnikov, zdravljenih z empirično kemoterapijo (KT) s platino ali taksani, pa so še vedno slabi, srednje celokupno preživetje je manj kot 10 mesecev. Za mnoge bolnike ostaja optimalna izbira najboljše možno podporno zdravljenje. Novi pristopi k obravnavi teh bolnikov se zdijo obetavni in so temeljit premik v paradigmi zdravljenja RNI; od zdravljenja, specifičnega za organ/tkivo, k zdravljenju, usmerjenemu na posameznega bolnika, ki temelji na genomskih spremembah njegovega tumorja. Prispevek povzema trenutne dokaze o uporabi vsakega od teh pristopov. Predstavljeno je tudi zdravljenje treh bolnikov z neugodnim RNI.

5. Retrospective analysis of treatment-naive Slovenian patients with metastatic melanoma treated with pembrolizumab : real-world experienceNežka Hribernik, Marko Boc, Janja Ocvirk, Jasna Knez Arbeiter, Tanja Mesti, Marija Ignjatović, Martina Reberšek, 2020, original scientific article Abstract: Based on recent data from clinical trials, the immune checkpoint inhibitor pembrolizumab prolongs survival and has a good toxicity profile in patients with advanced or metastatic melanoma. However, the question remains whether these results are transmitted into daily clinical practice. The aim of this study was to assess the efficacy and toxicity of pembrolizumab in treatment-naive patients with metastatic melanoma in everyday clinical practice in Slovenia and compare it to the results from clinical trials. Patients and methods. This observational retrospective cohort study included 138 consecutive metastatic treatment-naive melanoma patients treated with pembrolizumab at the Institute of Oncology Ljubljana in Slovenia, from January 2016 to December 2018. Patient and treatment characteristics were retrospectively collected from hospital data base. Statistical data was obtained using the SPSS software version 22. Survival rate was calculated with the Kaplan-Meier method. Observation period took place between January 2016 and the end of June 2019. Results. The estimated median overall survival (OS) was 25.1 months (95% CI, 14.6%35.6) and the median progressionfree survival (PFS) was 10.7 months (95% CI, 5.9%15.4). Among all patients, 29 (21.0%) achieved complete response, 31 (22.5%) partial response and 23 (16.7%) reached stable disease. The number of organs with metastatic involvement and the level of baseline lactate dehydrogenase (LDH) concentration had significant influence on survival rates. Immune-related adverse events (irAE) were reported in 88 (63%) patients, while grade 3%4 irAE occurred in 12 (8.7%). Due to toxicity, 16 (11.6%) patients discontinued the treatment. Conclusions. Our real-world data from single centre retrospective analysis of treatment-naive metastatic melanoma patients treated with pembrolizumab showed inferior median OS and similar median PFS, compared to the results from clinical trials. However, patients with normal serum levels of LDH and a small number of organs with metastatic involvement had comparable survival outcomes. Toxicity rates of pembrolizumab were quite similar. These results further support the use of pembrolizumab for metastatic treatment-naive melanoma patients.

10. Sistemsko zdravljenje melanomskih bolnikov z zasevki v centralnem živčnem sistemuNežka Hribernik, 2023, published scientific conference contribution Abstract: Bolniki z metastatskim melanomom, ki imajo možganske zasevke, so posebna podskupina melanomskih bolnikov z zelo slabim preživetjem. Pri obravnavi teh bolnikov je ključen multidisciplinaren pristop, ki vključuje tako lokalno zdravljenje (nevrokirurgija, radioterapija) kot specifično sistemsko onkološko zdravljenje. Z novimi možnostmi lokalne in sistemske terapije so se preživetja bolnikov z možganskimi zasevki izboljšala. Glede zaviralcev imunskih kontrolnih točk je kombinirana imunoterapija s PD-1/ CTLA 4 protitelesi uspešnejša napram mono-imunoterapiji. S kombinirano imunoterapijo je bil v randomiziranih kliničnih raziskavah pri bolnikih z asimptomatskimi možganskimi zasevki ugotovljen visok odgovor na zdravljenje. Ugotavljali so dolgotrajne remisije. Pri bolnikih s simptomatskimi možganskimi zasevki, ki so potrebovali sistemski glukokortikoid, tega uspeha niso beležili. Glede tarčne terapije z BRAF in MEK zaviralci je bil pri kombinaciji dabrafeniba in trametiniba dokazan hiter in visok delež odgovorov, vključno pri bolnikih, ki so prejemali sistemski glukokortikoid. Žal pa je bilo trajanje odgovorov kratko, povprečno manj kot 6 mesecev. Raziskujejo se novi načini zdravljenja, ki bodo dodatno izboljšali preživetja teh bolnikov.
