1. The role of neoadjuvant chemotherapy in patients with advanced (stage IIIC) epithelial ovarian cancerErik Škof, Sebastjan Merlo, Gašper Pilko, Borut Kobal, 2016, original scientific article Abstract: Primary treatment of patients with advanced epithelial ovarian cancer consists of chemotherapy either before (neoadjuvant chemotherapy, NACT) or after primary surgery (adjuvant chemotherapy). The goal of primary treatment is no residual disease after surgery (R0 resection) what is associated with an improvement in survival of patients. There is, however, no evidence of survival benefits in patients with R0 resections after prior NACT. Methods. We retrospectively reviewed the records of patients who were treated with diagnosis of epithelial ovarian cancer at Institute of Oncology Ljubljana in the years 2005%2007. The differences in the rates of R0 resections, progression free survival (PFS), overall survival (OS) and in five-year and eight-year survival rates between patients treated with NACT and patients who had primary surgery were compared. Results. Overall 160 patients had stage IIIC epithelial ovarian cancer. Eighty patients had NACT and eighty patients had primary surgery. Patients in NACT group had higher rates of R0 resection (42% vs. 20%; p = 0.011) than patients after primary surgery. PFS was 14.1 months in NACT group and 17.7 months after primary surgery (p = 0.213). OS was 24.8 months in NACT group and 31.6 months after primary surgery (p = 0.012). In patients with R0 resections five-year and eight-year survival rates were 20.6% and 17.6% in NACT group compared to 62.5% and 62.5% after primary surgery (p < 0.0001), respectively. Conclusions. Despite higher rates of R0 resections achieved by NACT, survival of patients treated with NACT was inferior to survival of patients who underwent primary surgery. NACT should only be offered to patients with advanced epithelial cancer who are not candidates for primary surgery.

8. Imunoterapija pri raku telesa materniceErik Škof, 2023, published scientific conference contribution Abstract: Nova molekularna klasifikacija raka telesa maternice je omogočila novo, usmerjeno zdravljenje bolnic z rakom telesa maternice. Glavno novost predstavlja imunoterapija z zaviralci imunskih nadzornih točk (zaviralci PD-1) pri bolnicah z metastatskim rakom telesa maternice v 2. liniji zdravljenja, po predhodnem zdravljenu s kemoterapijo. Evropska agencija za zdravila (EMA) je odobrila uporabo dveh zaviralcev PD-1 receptorjev - dostarlimab in pembrolizumab v monoterapiji v primeru, da gre za okvaro MMR proteinov v tumorju (dMMR/MSI-H karcinom). Odobrena je tudi kombinacija pembrolizumaba in lenvatiniba (zaviralec tirozin kinaz) v 2. liniji zdravljenja metastatske bolezni, po predhodnem zdravljenju s kemoterapijo, ne glede na status MMR proteinov, torej tudi v primeru, da ne gre za okvaro MMR proteinov v tumorju (pMMR/MSS karcinom). Pred kratkim so bili objavljeni rezultati, ki kažejo učinkovitost pembrolizumaba in dostarlimaba v kombinaciji s kemoterapijo v 1. liniji napredovale ali metastatske bolezni. V adjuvantnem zdravljenju zaenkrat še nimamo podatkov o učinkovitosti imunoterapije - potekajo klinične raziskave.

9. Neželeni učinki sistemskega zdravljenja rakaErik Škof, 2022, published scientific conference contribution Abstract: Pri beleženju neželenih učinkov sistemskega zdravljenja uporabljamo mednarodne kriterije “Common Terminology Criteria for Adverse Events”, ki jih je ustanovil Ameriški Nacionalni inštitut za zdravljenje raka. V prispevku prikazujemo definicije izrazov, ki jih uporabljamo pri opisovanju in vrednotenju neželenih učinkov zdravljenja. Po Zakonu o zdravilih in Pravilniku o farmakovigilanci zdravil za uporabo v humani medicini je poročanje o domnevnih neželenih učinkih za zdravstvene delavce obvezno. Prikazujemo osnovna navodila in informacije za prijavo neželenih učinkov zdravljenja.
