Povzetek: Izhodišča: Pandemija koronavirusne bolezni 2019 (covid-19) je zaradi epidemioloških ukrepov, zlasti spodbujanja fizične distance, marsikje po svetu pospešila uvajanje telemedicine v klinično prakso. Zato smo želeli pridobiti stališča onkoloških bolnikov in zdravnikov do tovrstne obravnave v onkologiji. Metode: K izpolnjevanju dveh ločenih kvantitativnih vprašal-nikov smo med 27. majem in 11. junijem 2020 prek elektronske pošte ter s pomočjo Slovenskega združenja organizacij bolnikov z rakom (ONKO NET) povabili bolnike z rakom, ki so bili bodisi na aktivnem zdravljenju bodisi na sledenju po zaključenem zdravljenju, in zdravnike onkologe. Dodatno je bil v Sektorju radioterapije Onkološkega inštituta Ljubljana izveden presečni dan za bolnike med obsevanjem. Rezultati: Na spletni ali natisnjen vprašalnik za bolnike je odgovorilo 475 bolnikov, od tega 310 (65,3 %) na aktivnem onko-loškem zdravljenju in 132 (27,8 %) v fazi sledenja. Skoraj polovica bolnikov (48,4 %) je kot primarno diagnozo navedla rak dojk. Več kot desetina vseh (11,3 %) je zaradi pandemije želela opustiti zdravniški pregled. V zasebnem življenju jih pametni telefon ali tablico uporablja 72,4 % in vsaj 30 % bolnikov bi bilo pripravlje-nih v bodoče pogosteje uporabljati telemedicinske storitve. Od 168 povabljenih zdravnikov jih je na vprašalnik odgovoril 101 (60 %) in ocenil, da bi s pomočjo telemedicine lahko opravil 21 % (0%80 %) vseh svojih storitev. Če bi se sami znašli v vlogi bolnika, bi bila prip-ravljena po telemedicini poseči dobra polovica sodelujočih (54,5 %). Zaključki: Uporaba telemedicine v onkologiji bi bila ob upošteva-nju nekaterih omejitev sprejemljiva za pomemben del bolnikov in zdravnikov

Povzetek: There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPAR[gamma]:Peroxisome proliferator-activated receptor, NF[kappa]B: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2[alpha]:Elongation initiation factor 2[alpha]). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT1R axis (AT1R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity.

Povzetek: Background: The introduction of targeted treatments for subsets of non-small cell lung cancer (NSCLC) has highlighted the importance of accurate molecular diagnosis to determine if an actionable genetic alteration is present. Few data are available for Central and Eastern Europe (CEE) on mutation rates, testing rates, and compliance with testing guidelines. Methods: A questionnaire about molecular testing and NSCLC management was distributed to relevant specialists in nine CEE countries, and pathologists were asked to provide the results of EGFR and ALK testing over a 1-year period. Results: A very high proportion of lung cancer cases are confirmed histologically/cytologically (75-100%), and molecular testing of NSCLC samples has been established in all evaluated CEE countries in 2014. Most countries follow national or international guidelines on which patients to test for EGFR mutations and ALK rearrangements. In most centers at that time, testing was undertaken on request of the clinician rather than on the preferred reflex basis. Immunohistochemistry, followed by fluorescent in situ hybridization confirmation of positive cases, has been widely adopted for ALK testing in the region. Limited reimbursement is a significant barrier to molecular testing in the region and a disincentive to reflex testing. Multidisciplinary tumor boards are established in most of the countries and centers, with 75-100% of cases being discussed at a multidisciplinary tumor board at specialized centers. Conclusions: Molecular testing is established throughout the CEE region, but improved and unbiased reimbursement remains a major challenge for the future. Increasing the number of patients reviewed by multidisciplinary boards outside of major centers and access to targeted therapy based on the result of molecular testing are other major challenges.

Povzetek: Background: A minority of European countries have participated in international comparisons with high level data on lung cancer. However, the nature and extent of data collection across the continent is simply unknown, and without accurate data collection it is not possible to compare practice and set benchmarks to which lung cancer services can aspire. Methods: Using an established network of lung cancer specialists in 37 European countries, a survey was distributed in December 2014. The results relate to current practice in each country at the time, early 2015. The results were compiled and then verified with co-authors over the following months. Results: Thirty-five completed surveys were received which describe a range of current practice for lung cancer data collection. Thirty countries have data collection at the national level, but this is not so in Albania, Bosnia- Herzegovina, Italy, Spain and Switzerland. Data collection varied from paper records with no survival analysis, to well-established electronic databases with links to census data and survival analyses. Conclusion: Using a network of committed clinicians, we have gathered validated comparative data reporting an observed difference in data collection mechanisms across Europe. We have identified the need to develop a welldesigned dataset, whilst acknowledging what is feasible within each country, and aspiring to collect high quality data for clinical research.

Povzetek: Background. There is a steady decline in cancer mortality in Western Europe (WE), but this trend is not so obvious in Central and Eastern Europe (CEE). One of the largest discrepancies between WE and CEE is the level of investment in cancer care. The objective of our analysis was to examine the correlation between mortality-to-incidence (M/I) ratio and expenditures on oncology drugs in CEE and WE. Materials and Methods. This cross-sectional analysis was done on publicly available data. Data on expenditures for oncology drugs were obtained from QuintilesIMS, and data on M/I ratio from Globocan. The main outcome was mortality-to-incidence ratio, and the primary analysis was performed by Spearman's rank correlation. Results. There is a large discrepancy in expenditure on oncology drugs per cancer case between WE and CEE, and within CEE. Average expenditure on oncology drugs per capita as well as per new cancer case was 2.5 times higher in WE than in CEE. Availability of oncology drugs was highest in Germany (100%), relatively similar in WE (average of 91%), but in CEE it ranged from 37% to 86%, with an average of 70%. Annual expenditures on all oncology drugs per new cancer case was significantly negatively correlated with the M/I ratio (Spearman's p = -0.90, p < .001). Conclusion. There is a financial threshold for oncology drugs per cancer case needed to increase survival. Based on significantly lower expenditures for oncology drugs in CEE in comparison with WE, more investment for drugs as well as better, more organized,value-oriented consumption is needed. Implications for Practice. Cancer is not treated equally successfully in Western Europe (WE) and in Central and Eastern Europe (CEE). This study showed that success in treatment of cancer is associated with the amount of money invested in oncology drugs. CEE countries spend on average 2.5 times less than WE countries for oncology drugs per new cancer case. These findings should be used by healthcare providers and oncologists struggling for more resources and better, more organized, evidence-based allocation of these resources as well as better oncology outcomes.
