Background: Patients with acute coronary syndrome with signs of ongoing myocardial ischaemia at first medical contact should be indicated for immediate invasive treatment., Aim: To assess the incidence, treatment strategies and outcomes of acute coronary syndrome in a large unselected cohort of patients with respect to the signs of ongoing myocardial ischaemia., Methods: The CZECH-3 registry included 1754 consecutive patients admitted for suspected acute coronary syndrome to 43 hospitals during a 2-month period in the autumn of 2015. Acute coronary syndrome with ongoing myocardial ischaemia was defined by the presence of persistent/recurrent chest pain/dyspnoea and at least one of the following: persistent ST-segment elevation or depression, bundle branch block, haemodynamic or electric instability due to suspected ischaemia. Major adverse cardiac events (death, reinfarction, stroke, unexpected revascularisation, stent thrombosis) and severe bleeding according to Bleeding Academic Research Consortium criteria were evaluated at 30 days., Results: Acute coronary syndrome was ruled out during the hospital stay in 434 (24.7%) patients. Out of 1280 patients with confirmed acute coronary syndrome, 732 (57%) had clinical signs of ongoing myocardial ischaemia at first medical contact. Coronary angiography was performed in 94.7% of patients with confirmed acute coronary syndrome with ongoing myocardial ischaemia and 89% of patients with confirmed acute coronary syndrome without ongoing myocardial ischaemia ( P <0.001). The major adverse cardiac event rate was 9.8% for patients with confirmed acute coronary syndrome with ongoing myocardial ischaemia and 5.5% for patients without ongoing myocardial ischaemia ( P =0.005), the 30-day severe bleeding rate was 1.6% and 1.5% ( P =1.0). Patients with ongoing myocardial ischaemia admitted to regional hospitals had higher major adverse cardiac event rates compared with patients admitted directly to cardiocentres with percutaneous coronary intervention capability (13.3% vs. 8.2%, P =0.034)., Conclusions: Ongoing myocardial ischaemia was present in more than half of patients hospitalised with acute coronary syndrome. These very high-risk patients may benefit from direct admission to percutaneous coronary intervention-capable centres.

Patients with clinically node-positive bladder cancer have a poor prognosis, with many receiving only palliative chemo- therapy. We evaluated oncological results in bladder cancer patients with clinically regional and supraregional lymph- adenopathy treated with induction chemotherapy (IC) and consolidative cystectomy. Twenty-five patients with clinically node-positive bladder cancer (including pelvic and retroperitoneal nodes) were treated with 2-4 cycles of IC followed by consolidative cystectomy between 2010 and 2016. Pathologic complete response (pCR) was defined as no residual tumor in the final specimen (ypT0N0).The 3-year cancer-specific (CSS) and recurrence-free survival (RFS) for the whole cohort were 52% and 39%, respectively. The 3-year RFS differed according to volume of nodal metastases, the rates were 56% for minimal nodal disease (cN1) versus 33% for cN2-3 and 0% for cM1 disease (p<0.001). pCR was seen in 7 (28%) patients; 50% in cN1 versus 13% in cN3-M1. pCR associated with 3-year CSS of 80% versus 45% in patients with persistent disease after IC. In conclusion, a multimodal approach to patients with clinically node-positive bladder cancer, consisting of IC followed by consolidative surgery, may achieve long-term survival in selected patients. Better results may be expected in patients with initially minimal nodal burden and complete pathologic response to chemotherapy. Further studies are warranted to improve patient selection for consolidative surgery, especially with supra-regional metastases.

Background: Multiple myeloma (MM) is a cancer of plasma cells with an incidence of 4.8 cases per 100,000 population in the Czech Republic in 2014; the burden of MM in the Czech Republic is moderate when compared to other European countries. This work brings the latest information on MM epidemiology in the Czech population., Material and Methods: The Czech National Cancer Registry is the basic source of data for the population-based evaluation of MM epidemiology. This database also makes it possible to assess patient survival and to predict probable short-term as well as long-term trends in the treatment burden of the entire population., Results: According to the latest Czech National Cancer Registry data, there were 504 new cases of MM and 376 deaths from MM in 2014. Since 2004, there has been a 26.9% increase in MM incidence and an 8.3% increase in MM mortality. In 2014, there were 1,982 persons living with MM or a history of MM, corresponding to a 74.4% increase when compared to MM prevalence in 2004. The 5-year survival of patients treated in the period 2010-2014 was nearly 40%., Conclusion: The available data make it possible to analyse long-term trends in MM epidemiology and to predict the future treatment burden as well as treatment results.Key words: multiple myeloma - epidemiology - Czech National Cancer Registry - Registry of Monoclonal Gammopathies - Czech Republic.

Background: Cancer burden in the Czech population ranks among the highest worldwide, which introduces a strong need for a prospective modelling of cancer incidence and prevalence rates. Moreover, a prediction of number of cancer patients requiring active antitumor therapy is also an important issue. This paper presents the stage-specific predictions of cancer incidence and prevalence, and the stage- and region-specific patients requiring active antitumor therapy for the most common cancer diagnoses in the Czech Republic for years 2015 and 2020. The stage-specific estimates are also presented with regard to the treatment phase as newly diagnosed patients, patients treated for non-terminal recurrence, and patients treated for terminal recurrence., Patients and Methods: Data of the Czech National Cancer Registry from 1977 to 2011 has been used for the analysis, omitting the records of patients diagnosed as death certificate only or at autopsy. In total, 1,777,775 incidences have been considered for the estimation using a statistical model utilizing solely the population-based cancer registry data. All estimates have been calculated with respect to the changing demographic structure of the Czech population and the clinical stage at diagnosis., Results: Considering year 2011 as the baseline, we predict 89%, 15%, 31% and 32% increase in prostate, colorectal, female breast and lung cancer incidence, respectively, in 2020 resulting in 13,153, 9,368, 8,695, and 8,604 newly dia-g--nosed cancer patients in that year, respectively. Regarding cancer prevalence in 2020, the estimated increase is 140%, 40%, 51%, and 17% for prostate, colorectal, female breast and lung cancer, respectively, meaning that more than 100,000 prevalent female breast cancer patients as well as more than 100,000 prevalent prostate cancer patients are expected in the Czech Republic. The estimated numbers of patients requiring active antitumor therapy for prostate, colorectal, female breast and lung cancer in the Czech Republic in 2020 are 23,652, 14,006, 14,759 and 8,272; respectively., Conclusions: The analysis documents a serious increase in cancer incidence and prevalence in the Czech Republic in years 2015 and 2020 when compared to the situation in 2011. Regarding the estimated numbers of patients requiring active antitumor therapy, the model confirms a continuous increase that must be accounted for in the future planning of health care in the Czech Republic.

Background: The Czech Republic ranks among the countries with the highest cancer burden in Europe as well as worldwide. The purpose of this study is to summarize longterm trends in the cancer burden and to provide up-to-date estimates of incidence and mortality rates after 2011., Data and Methods: The Czech National Cancer Registry (CNCR) was instituted in 1977 and contains information collected over a 34-year period of standardized registration covering 100% of cancer diagnoses within the entire Czech population. The CNCR analysis is supported by demographic data and by the Death Records Database. An overview of the epidemiology of malignant tumors in the Czech population is available online at www.svod.cz., Results: All neoplasms, including nonmelanoma skin cancer, reached a crude incidence rate of almost 802 cases per 100,000 men and 681 cases per 100,000 women in 2011. The annual mortality rate exceeded 258 deaths per 100,000 individuals; in other words, more than 27,000 individuals die of cancer each year. The overall incidence of malignancies has increased with a growth index of +27.6% during the last decade (2001- 2011), while the mortality rate has been stabilized over the time span (growth index in 2001- 2011: - 5.0%). Consequently, the prevalence has significantly increased in the observed period and exceeded 475,000 cases in 2011. In addition to demographic aging of the Czech population, the cancer burden has also increased due to the growing incidence of multiple primary tumors (recently more than 15% of the total incidence). The most frequent diagnoses include colorectal cancer, lung cancer, breast cancer, and prostate cancer. Although some neoplasms are increasingly diagnosed at an early stage (e. g. the proportion of stage I or II was 75.3% for female breast cancer and 84.2% for skin melanoma), the numbers of early diagnosed cases are generally insufficient, even in the case of highly prevalent cancers such as colorectal carcinoma (only 46.1% of incident cases are diagnosed at stage I or II, according to recent data)., Conclusion: Population-based data on malignant tumors are available in the Czech Republic. The data survey can help us define national cancer management priorities. The current priority is to achieve a sustained reduction of cases diagnosed at an advanced stage and reduction of the significant regional differences in diagnostic efficiency.
