7. Long term results of radiotherapy in vulvar cancer patients in Slovenia between 1997-2004Helena Barbara Zobec Logar, 2017, original scientific article Abstract: The aim of this retrospective single institution study was to analyse long term results of vulvar cancer treatment with conventional 2D radiotherapy in Slovenia between years 1997%2004. Patients and methods. Fifty-six patients, median age 74.4 years +/- 9.7 years, mainly stage T2 or T3, were included in the study. All patients were treated with radiotherapy, which was combined with surgery (group A), used as the primary treatment (group B) or at the time of relapse (group C). Chemotherapy was added in some patients. Histology, grade, lymph node status, details of surgery, radiation dose to the primary tumour, inguinofemoral and pelvic area as well as local control (LC) and survival were evaluated. Results. Overall survival (OS), disease specific survival (DSS) and LC rates at 10-years for all patients were as follows: 22.7%, 34.5% and 41.1%, respectively. The best 10-years results of the treatment were achieved in the primary operated patients treated with adjuvant radiotherapy +/-chemotherapy (OS 31.9%, DSS 40.6% and LC 47.6%). Positive lymph nodes had a strong influence on LC. In case of positive nodes LC decreased by 60% (p = 0.03) and survival decreased by 50% (p = 0.2). There was a trend to a better LC with higher doses % 54.0 Gy (p = 0.05). Conclusions. The best treatment option for patients with advanced vulvar cancer is combined treatment with surgery and radiotherapy +/- chemotherapy, if feasible. Radiotherapy with the dose of % 54.0 Gy should be considered to achieve better LC if positive adverse factors are present.

8. Gamma-enolase : a well known tumour marker, with a less-known role in cancerTjaša Vižin, Janko Kos, 2015, review article Abstract: Gamma-enolase, known also as neuron-specific enolase (NSE), is an enzyme of the glycolytic pathway, which is expressed predominantly in neurons and cells of the neuroendocrine system. As a tumour marker it is used in diagnosis and prognosis of cancer; however, the mechanisms enrolling it in malignant progression remain elusive. As a cytoplasmic enzyme gamma-enolase is involved in increased aerobic glycolysis, the main source of energy in cancer cells, supporting cell proliferation. However, different cellular localisation at pathophysiological conditions, proposes other cellular engagements. The C-terminal part of the molecule, which is not related to glycolytic pathway, was shown to promote survival of neuronal cells by regulating neuronal growth factor receptor dependent signalling pathways, resulting also in extensive actin cytoskeleton remodelling. This additional function could be important also in cancer cells either to protect cells from stressful conditions and therapeutic agents or to promote tumour cell migration and invasion. Gamma-enolase might therefore have a multifunctional role in cancer progression: it supports increased tumour cell metabolic demands, protects tumour cells from stressful conditions and promotes their invasion and migration.

9. Cancer patients’ survival according to socioeconomic environment in a high-income country with universal health coverageVesna Zadnik, Tina Žagar, Sonja Tomšič, Ana Mihor, Katarina Lokar, 2022, original scientific article Abstract: Despite having an established systematic approach to population survival estimation in Slovenia, the influence of socioeconomic environment on cancer patients’ survival has not yet been evaluated. Thus, the main aim of our study was to quantify the potential impact of socioeconomic environment on cancer patients’ survival in our population in the 21st century. The net survival was calculated and stratified into quintiles of Slovenian version of the European Deprivation Index for all adult cancer patients diagnosed between 2004 and 2018 using the national cancer registry data. After accounting for basic demographic variables (age and gender), differences in stage at diagnosis, as well as the impact of the cancer treatment improvements over time, we found that cancer patients in Slovenia with lower socioeconomic status experience worse survival and have higher mortality. In particular, the odds of dying from oral, stomach, colorectal, liver, pancreatic, lung, breast, ovarian, corpus uteri, prostate, and bladder cancers, as well as for melanoma, leukemia, and non-Hodgkin lymphoma, are significantly higher in the socioeconomically most deprived group of patients compared to the most affluent group. The inequalities in cancer burden we found could help decision-makers to better understand the magnitude of this problem.

10. Carboxypeptidase cathepsin X defines a multifunctional role of gamma-enolase in cancerTjaša Vižin, Anja Pišlar, Ib Jarle Christensen, Hans Jørgen Nielsen, Pika Meško-Brguljan, Janko Kos, 2022, original scientific article Abstract: Gamma-enolase enzymatic activity is involved in glycolysis, a prevalent process in cancer cell metabolism. Additionally, gamma-enolase has a pro-survival function, exhibited through the active site at the C-terminal end of the molecule. This activity is regulated by cysteine peptidase cathepsin X, which cleaves two amino acids at C-terminal end of gamma-enolase. In clinical practice, the determination of gamma-enolase as a tumour marker does not differ between total, uncleaved and C-terminally cleaved forms. However, levels of uncleaved gamma-enolase alone may provide additional clinical information. In this study we analysed cathepsin X, C- terminally uncleaved and total gamma-enolase in tumour cell lines and sera from 255 patients with colorectal cancer (CRC) by western blot, immunoprecipitation, enzymatic activity, ELISAs and ECLIA. Results show that uncleaved gamma-enolase, rather than total gamma- enolase, exhibits different levels in cells, being the highest in those, derived from metastatic sites or highly invasive tumours. Gamma-enolase is secreted into the extracellular space predominantly as an uncleaved form and levels were congruent to those within the cells. Furthermore, levels of uncleaved gamma-enolase in cells are inversely related to cathepsin X protein level and its enzymatic activity. Uncleaved gamma-enolase is also predominant form in sera of patients with CRC. Both forms exhibit similar stage dependent distribution, with slightly elevated levels in stage IV patients. Higher levels of total gamma-enolase are significantly related to shorter survival in patients with metastatic CRC. Results support evidence of additional pro-survival function of gamma-enolase in cancer. Future studies should focus on analysis of uncleaved gamma-enolase in tumour samples, which may provide additional relations to clinical indicators of disease progression.
