ABSTRACT

BACKGROUND: The management of cervical cancer patients with intraoperative detection of lymph node involvement remains controversial. Since all these patients are referred for (chemo)radiation after the surgery, the key decision is whether radical hysterectomy should be completed as originally planned, taking into account an additional morbidity associated with extensive surgical dissection prior to adjuvant treatment. The ABRAX study investigated whether completing a radical uterine procedure is associated with an improved oncological outcome of such patients. PATIENTS AND METHODS: We performed retrospective analyses of 515 cervical cancer patients (51 institutions, 19 countries) who were referred for primary curative surgery between 2005 and 2015 (stage IA-IIB, common tumour types) in whom lymph node involvement was detected intraoperatively. Patients were stratified according to whether the planned uterine surgery was completed (COMPL group, N = 361) or abandoned (ABAND group, N = 154) to compare progression-free survival. Definitive chemoradiation was given to 92.9% patients in the ABAND group and adjuvant (chemo)radiation or chemotherapy to 91.4% of patients in the COMPL group. RESULTS: The risks of recurrence (hazard ratio [HR] 1.154, 95% confidence intervals [CI] 0.799-1.666, P = 0.45), pelvic recurrence (HR 0.836, 95% CI 0.458-1.523, P = 0.56), or death (HR 1.064, 95% CI 0.690-1.641, P = 0.78) were not significantly different between the two groups. No subgroup showed a survival benefit from completing radical hysterectomy. Disease-free survival reached 74% (381/515), with a median follow-up of 58 months. Prognostic factors were balanced between the two groups. FIGO stage and number of pelvic lymph nodes involved were significant prognostic factors in the whole study cohort. CONCLUSION: We showed that the completion of radical hysterectomy does not improve survival in patients with intraoperatively detected lymph node involvement, regardless of tumour size or histological type. If lymph node involvement is confirmed intraoperatively, abandoning uterine radical procedure should be considered, and the patient should be referred for definitive chemoradiation.

ABSTRACT

Triple-positive breast cancer (TPBC), i.e. HER2-positive (HER2+) and hormone receptors-positive breast cancer, is a specific subgroup of breast cancers. TPBC biology is characterized by strong mutual interactions between signaling pathways stimulated by estrogens and HER2 amplification. The present study aims to carry out a population-based analysis of treatment outcomes in a cohort of hormone receptor (HR) positive and negative breast cancer patients who were treated with anti-HER2 therapy in the Czech Republic. The BREAST research database was used as the data source for this retrospective analysis. The database covers approximately 95% of breast cancer patients treated with targeted therapies in the Czech Republic. The analysis included 6,122 HER2-positive patients. The patients were divided into two groups, based on estrogen receptor (ER) or progesterone receptor (PR) positivity: hormone receptor negative (HR-) patients had both ER- and PR-negative tumors (n=2,518), unlike positive (HR+) patients (n=3,604). HR+ patients were more often diagnosed premenopausal at the time of diagnosis, presented more often at stage I or II and their tumors were less commonly poorly differentiated. The overall survival (OS) was significantly higher in subgroups of HR+ patients according to treatment setting. When evaluated by stages, significantly higher OS was observed in HR+ patients diagnosed at stages II, III, and IV and regardless of tumor grade.

ABSTRACT

OBJECTIVES: HIV-infected individuals are at higher risk of non-AIDS diseases associated with procoagulant status. Microparticles are elevated in disorders associated with thrombosis (e.g., cardiovascular diseases). We investigated the association between microparticle levels in untreated and treated HIV-infected subjects, and determined the association with immune status, viral replication, and duration of antiretroviral therapy. PATIENTS AND METHODS: We included 144 HIV-infected subjects, including 123 on antiretroviral therapy (ART) and 21 before treatment initiation. A control group of 40 HIV-negative healthy adults matched for age and sex was used for comparison of microparticle levels. Treated subjects were divided into five groups depending on the period of antiretroviral exposure. Statistically significant differences were determined by Kruskal-Wallis test and Chi2 test. The relation between microparticles and other parameters was assessed using Spearman's coefficient of correlation. RESULTS: Microparticle levels were significantly higher in treated and untreated HIV-infected subjects than in non-HIV-infected controls (P<0.001). The microparticle level was similar between the groups on treatment (P=0.913). No association between the microparticle level and CD4+ count, CD4+/CD8+ ratio, number of HIV-1 RNA copies, or duration of exposure to antiretroviral treatment was observed. CONCLUSION: Increased levels of microparticles may be due to processes independent of viral replication and CD4+ cell count, and microparticle release might persist even during viral suppression by antiretroviral treatment. Elevated microparticle levels might occur in response to other triggers.

ABSTRACT

BACKGROUND: The evaluation of the long-term risk of major adverse cardiovascular events and cardiac death in patients after acute myocardial infarction (AMI) is an established clinical process. Laboratory markers may significantly help with the risk stratification of these patients. Our objective was to find the relation of selected microRNAs to the standard markers of AMI and determine if these microRNAs can be used to identify patients at increased risk. METHODS: Selected microRNAs (miR-1, miR-133a, and miR-499) were measured in a cohort of 122 patients from the PRAGUE-18 study (ticagrelor vs. prasugrel in AMI treated with primary percutaneous coronary intervention (pPCI)). The cohort was split into two subgroups: 116 patients who did not die (survivors) and 6 patients who died (nonsurvivors) during the 365-day period after AMI. Plasma levels of selected circulating miRNAs were then assessed in combination with high-sensitivity cardiac troponin T (hsTnT) and N-terminal probrain natriuretic peptide (NT-proBNP). RESULTS: miR-1, miR-133a, and miR-499 correlated positively with NT-proBNP and hsTnT 24 hours after admission and negatively with left ventricular ejection fraction (LVEF). Both miR-1 and miR-133a positively correlated with hsTnT at admission. Median relative levels of all selected miRNAs were higher in the subgroup of nonsurvivors (N = 6) in comparison with survivors (N = 116), but the difference did not reach statistical significance. All patients in the nonsurvivor subgroup had miR-499 and NT-proBNP levels above the cut-off values (891.5 ng/L for NT-proBNP and 0.088 for miR-499), whereas in the survivor subgroup, only 28.4% of patients were above the cut-off values (p = 0.001). CONCLUSIONS: Statistically significant correlation was found between miR-1, miR-133a, and miR-499 and hsTnT, NT-proBNP, and LVEF. In addition, this analysis suggests that plasma levels of circulating miR-499 could contribute to the identification of patients at increased risk of death during the first year after AMI, especially when combined with NT-proBNP levels.

ABSTRACT

BACKGROUND: Plasma cell leukemia (PCL) is a rare but most aggressive form of monoclonal gammopathies. PCL is characterized by the presence of clonal plasma cells in peripheral blood. There are two forms of PCL - primary which presents de novo in patients with no evidence of previous multiple myeloma and secondary which is a leukemic transformation of relapsed or refractory dis-ease in patients with previously recognized multiple myeloma. MATERIALS AND METHODS: This is the first study to provide information on PCL epidemiology in the Czech population us-ing The Czech National Cancer Registry (CNCR) as the basic source of data for the population-based evaluation of PCL epidemiology. RESULTS: Accord-ing to CNCR data, there were on average six newly dia-gnosed cases of PCL and four deaths caused by PCL each year in the Czech Republic in the period 2000- 2015. PCL incidence in the Czech Republic was reported at 0.57 per million in 2000- 2015. We suppose that most reported cases of PCL are primary PCL because secondary PCL is a relapse of a previously reported myeloma and, in most cases, is not coded as an independent dia-gnosis in the CNCR. CONCLUSION: Data from registries such as the CNCR can provide useful information on epidemiology of various dis-eases. These data, however, have several limitations, such as dia-gnostic criteria and proper cod-ing of not only the dis-ease itself, but also its various forms. These limitations have to be taken into account dur-ing the process of results interpretation. Key words plasma cell leukemia -  epidemiology -  Czech National Cancer Registry (CNCR) -  Czech Republic.

ABSTRACT

OBJECTIVE: Sentinel lymph node (SLN) biopsy has been increasingly used in the management of early-stage cervical cancer. It appears in guidelines as an alternative option to systematic pelvic lymphadenectomy. The evidence about safety is, however, based mostly on retrospective studies, in which SLN was combined with systematic lymphadenectomy. MATERIALS AND METHODS: SENTIX is a prospective multicenter trial aiming to prove that less-radical surgery with SLN is non-inferior to treatment with systematic pelvic lymphadenectomy. The primary end point is recurrence rate; the secondary end point is the prevalence of lower-leg lymphedema and symptomatic pelvic lymphocele. The reference recurrence rate was set up conservatively at 7% at 24 months after treatment. With a sample size of 300 patients treated per protocol, the trial is powered to detect a non-inferiority margin of 5% (90% power, p = 0.05) for recurrence rate, 30% reduction in the prevalence of symptomatic lymphocele or lower-leg lymphedema, with reference rates of 30% and 6% at 12 months (p = 0.025, Bonferroni correction). The patients eligible for SENTIX have stage IA1/LVSI+, IA2, IB1 (<2 cm for fertility sparing), with negative LN on pre-operative imaging. Intra-operatively, patients are excluded when there is a failure to detect SLN on both sides of the pelvis in cases of more advanced cancer (stage >IB1), or a positive intra-operative SLN assessment. The quality of SLN pathology evaluation will be assessed by central review. Three interim safety analyses are pre-planned when 30, 60, 150 patients complete 12 months' follow-up. CONCLUSIONS: The first patient was enrolled into the study in June 2016 and, by June 2018, 340 patients had been enrolled. The first analysis of secondary outcomes should be available in 2019 and the oncological outcome of 300 patients at the end of 2021. The trial is registered as a CEEGOG trial (CEEGOG CX-01), ENGOT trial (ENGOT-Cx 2), and at the ClinicalTrials.gov database (NCT02494063).

ABSTRACT

Although falls are more prevalent as ageing proceeds, it cannot be assumed that they happen due to ageing alone. The retrospective cohort study of data was targeted to make an analysis of prevalence of falls in anaemic patients in comparison to the non-anaemic elderly admitted to the acute geriatric department and evaluation of pertinent influence of age, gender and immobility on occurrence of falls. During the considered period of four years (2012-2016) the authors treated 9 363 elderly patients aged 79,9±8,6 years (in the majority of them 65+ years). Among them there were 8 809 non-anaemic and subgroup of 551 old anaemic patients (aged 81±7 years) with decreased haemoglobin (<110 g/l). Falls at hospital admission in average was present in 1 766 non-anaemic persons (20%) in comparison to 380 falls among anaemic patients (68,6%). Prevalence in anaemic subgroup is statistically significant higher (p<0,005). Also relation between falls and age, ADL and MMSE test and mobility is highly statistically significant (p<0,001). Meaningfully higher is occurrence of repeated falls in the anaemic subgroup in comparison to the non-anaemic one (41,2 vs 1,7%). The occurrence of falls in female gender in comparison to men is statistically significant higher in non-anaemic patients, not in anaemic group. Authors emphasize that anaemia appears to us as significant risk factor for falls in the elderly.

ABSTRACT

The purpose of this study is to summarize incidence and trends in the pediatric cancer burden in the Czech Republic over the period 1994-2014. The recently established Childhood Cancer Registry was combined with retrospective data from the Czech National Cancer Registry to analyze the annual patterns of incidence and long-term trends of pediatric cancer patients aged 0-14 years diagnosed between 1994 and 2014. Malignancies were classified according to the International Classification of Childhood Cancer. The distribution of incidence was stratified according to gender, age at diagnosis, type of cancer and geographic area. Annual age-standardized rates were adjusted using the world standard population. Changes over time were quantified as the average annual percentage change. This analysis comprised records of 5,605 children diagnosed with cancer within the period 1994-2014, annually 267 records on average; the overall age-standardized average annual incidence rate was 169 cases per million. Boys were affected more frequently than girls: the M/F crude incidence ratio was 1.2:1. The highest incidence rates were observed for ICCC groups I (27.8%), III (21.8%), II (12.4%) and IV (7.8%); other groups formed 30.2%. There are significant differences in the geographic distribution of incidence between regions. A borderline statistically significant increase (0.6%) in the overall average annual percentage change was detected between 1994 and 2014 (95% CI: 0.01 to 1.12; p = 0.05). This study provides reliable recent information on trends in the incidence of childhood cancers in the Czech Republic.

ABSTRACT

MATERIAL AND METHODS: Oleogel-S10, an ointment containing betulin-rich triterpene dry extract from birch bark was tested in an open, blindly evaluated, prospective, controlled, randomized multicentre study to improve wound healing in donor sites. The primary endpoint was time to wound closure, and secondary endpoints were scar related measurements at the time of wound closure, and 3 and 12 months after wound closure (POSAS, laser speckle contrast analysis, viscoelastic analysis). RESULTS: We report the results from a single centre (Department of Burns and Reconstructive Surgery, University Hospital Brno) of this phase III clinical trial. A total of 32 patients (25 men and 7 women) were included with the mean patient age of 41.8 years (SD, ±11.66). The mean extent of patients donor sites in the study was 56.77cm2 (SD, ±20.39). Median healing time of the verum group (Oleogel-S10) was 7 days (95% Confidence Interval 7-8 days) and for controls 8 days (95% CI 7-10 days). Comparison of POSAS data from the verum group revealed significantly lower values at all three time points as compared to the controls. Perfusion of scars of the verum group reached on average of 115 perfusion units at the end of treatment; the average was 69.8 perfusion units at the 3-month follow-up and 50.2 perfusion units at the 12-month follow-up. Control sites displayed significantly higher values at all time points (122.2 perfusion units, 73.9 perfusion units, 52.2 perfusion units). Significant differences were detected in the skins viscoelastic properties, with sites treated with Oleogel-S10 displaying more favourable values. CONCLUSION: In our results, we demonstrate the significant effectiveness of Oleogel-S10 in donor sites healingKeywords: Donor site, Triterpenes, Oleogel-S10, wound closure.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: Malignant tumors of the small bowel are relatively uncommon neoplasms; their incidence is around 1.5 per 100,000 inhabitants in the Czech Republic. METHOD: 104 patients underwent a resection of the small bowel because of a primary or secondary tumor over the 10-year period between 20062015 at the Masaryk Memorial Cancer Institute. Data from these patients was reviewed retrospectively. Survival rates were analyzed using the Kaplan-Meier method. RESULTS: We observed 45 primary and 59 secondary tumors. The group of primary malignancies included 12 adenocarcinomas, 14 cases of GIST and 19 cases of NET. Neuroendocrine tumors showed the best prognosis with a 62% probability of five-year survival. Patients with gastrointestinal stromal tumors had a 39% probability of five-year survival and those with adenocarcinomas had a 32% probability of five-year survival. Secondary tumors were caused mostly by metastatic colorectal carcinoma (22 times), malignant melanoma (11 times) and ovarian cancer (10 times). The probability of five-year survival was 15% in the group of secondary tumors. CONCLUSION: Malignant tumors of the small intestine are rare, but their incidence has increased in the last decades. The main prognostic factors include advancement of the tumor and radicality of surgical resection.Key words: small bowel tumors - adenocarcinoma - sarcoma - NET - GIST - lymphoma.

ABSTRACT

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.

ABSTRACT

BACKGROUND: The Registry of Monoclonal Gammopathies (RMG) was established by the Czech Myeloma Group in 2007. RMG is a registry designed for the collection of clinical data concerning diagnosis, treatment, treatment results and survival of patients with monoclonal gammopathies. Data on patients with monoclonal gammopathy of undetermined significance (MGUS), Waldenström macroglobulinaemia (WM), multiple myeloma (MM) or primary AL ("amyloid light-chain") amyloidosis are collected in the registry. DATA: Nineteen Czech centres and four Slovak centres currently contribute to the registry. The registry currently contains records on more than 5,000 patients with MM, almost 3,000 patients with MGUS, 170 patients with WM and 26 patients with primary AL amyloidosis, i.e. more than 8,000 records on patients with monoclonal gammopathies altogether. RESULTS: This paper describes technology employed for the collection, storage and subsequent online visualisation of data. The CLADE-IS platform is introduced as a new system for the collection and storage of data from the registry. The form structure and functions of the new system are described for all diagnoses in general; these functions facilitate data entry to the registry and minimise the error rate in data. Publicly available online visualisations of data on patients with MGUS, WM, MM or primary AL amyloidosis from all Czech or Slovak centres are introduced, together with authenticated visualisations of data on patients with MM from selected centres. CONCLUSION: The RMG represents a data basis that makes it possible to monitor the disease course in patients with monoclonal gammopathies on the population level.Key words: Registry of Monoclonal Gammopathies - RMG - registries - monoclonal gammopathies - CLADE-IS - data visualisation - database.

ABSTRACT

BACKGROUND: Monoclonal gammopathy of undetermined significance (MGUS) and smouldering multiple myeloma (SMM) are premalignant stages of multiple myeloma (MM). MM is a malignancy of plasma cells, which is associated with a median overall survival of 5 to 7 years. MM accounts for approximately 10% of hematological malignancies. PATIENTS AND METHODS: Descriptive analysis of data from 19 Czech centres collected in the Registry of Monoclonal Gammopathies (RMG) was performed. RESULTS: Over the last 10 years of prospective collection of data, together with retrospectively recorded data on patients diagnosed before the registry establishment, data on 7,467 patients with either asymptomatic or symptomatic form of MM have been gathered. Validation criteria for the analysis were met by 2,506 MGUS patients, 400 SMM patients and 4,738 MM patients. The median duration of follow-up was 4.3 years in MGUS patients and 2.4 years in SMM patients. The overall risk of progression from MGUS to malignancy was 1.7% per year. The risk of progression from SMM to MM was highest in the 1st years after diagnosis: overall, this risk was 16.6% per year. The median duration of follow-up was 2.8 years in MM patients. The median overall survival from the diagnosis was 5.7 years. The median OS from treatment initiation/progression-free survival decreased from 60.5/21.0 months in the 1st line therapy to 34.3/12.4 months in the 2nd line therapy, 22.6/8.9 months in the 3rd line therapy and 13.8/5.8 months in the 4th or higher line therapies. Thanks to the availability of novel drugs for MM treatment in the Czech Republic, treatment strategies have changed dramatically over the last decade. CONCLUSION: RMG is a registry designated for the collection of data on diagnosis, treatment, treatment results and survival of patients with monoclonal gammopathies in the long-term follow-up. RMG is a valuable source of data from real clinical practice.Key words: registries - monoclonal gammopathy of undetermined significance - smouldering multiple myeloma - multiple myeloma - progression - treatment - survival.

ABSTRACT

GOAL: Determination of basic epidemiological parameters of burn patients with micromycetes infection. Identification of the most important micromycetes in burn patients. MATERIAL AND METHODS: Monocentre retrospective study enrolling all adult burn patients who were hospitalized between 2007 and 2015 and in whom micromycetes were isolated during hospitalization. ABSI index (Abbreviated Burn Severity Index) was used to evaluate severity of thermal trauma. Results were statistically analysed. RESULTS: There were 61 patients with thermal trauma identified in total during the period of observation, and there were yeast or fibrous fungi isolated. There were 37 males and 24 females (M:F ratio - 1.5:1) in this group. The average age of patients was 57.3 years (29 patients were aged up to 60 years, 32 patients were over the age of 60 years, inclusive). 6 patients died (lethality was 9.8%). The average extent of the burn area was 21.6% TBSA (median 14.0%). There were 90 strains of micromycetes cultured in total in these patients (79 yeasts, 11 fibrous fungi). Micromycetes were isolated from burn area in 30 patients, from the lower airways in 19 patients, from the urogenital area in 15 patients and from blood culture in 7 patients. Non-albicans Candida species were predominant among yeasts (60 strains); Candida albicans was isolated 16 times in total. Aspergillus fumigatus (4 isolations) and Fusarium species (2 isolations) were predominant species among fibrous fungi. CONCLUSION: We successfully identified the basic epidemiological parameters in burn patients with micromycetes infection, similarly to the most important yeasts and fibrous fungi causing infection in these patients.

ABSTRACT

BACKGROUND: Survival rate of breast cancer patients has improved significantly in recent years. Cancer diagnosis represents a great psychological distress for patients which may not stem solely from the disease itself. Patients may experience higher distress even several years after treatment. PATIENTS AND METHODS: The study was carried out at the Department of Obstetrics and Gynecology and Department of Internal Medicine, Haematology and Oncology, Faculty Hospital Brno. Results of 85 patients at 4.5 years after diagnosis of breast cancer compared to 72 healthy controls are presented in this paper. The data were collected in the form of semi-structured interviews, from the patients medical records and by Symp-tom Check List-90. RESULTS: The overall rate of psychological distress (GSI) 4.5 years after breast cancer dia-gnosis does not differ significantly (p = 0.703) from the healthy population. Also, we did not find any statistically significant relationship between the observed factors and the level of psychological distress in breast cancer patients. CONCLUSION: Screening investigation showed no difference in the psychological distress in breast cancer patients 4.5 years following diagnosis, compared with the healthy population.

ABSTRACT

UNLABELLED: The objective of this study was to determine the prevalence of infectious complications in burn patients requiring intensive care in a one-day multicenter study encompassing burn centers in various European countries. MATERIAL AND METHODS: The European Burns Association database identified 87 centers in Western and Eastern Europe, 27 of which agreed to cooperate. American Burn Association recommendations were used for diagnosis of various infectious complications in patients with thermal trauma. RESULTS: From those centers, we randomly assigned 134 patients (44 women) to the analysis. Mean age of the group was 40.39 ± 22.17(SD) years. Mean abbreviated burn severity index was 7.5±2.54, mean size of burned area was 30.49 ± 20.14% of total body surface area. Mean length of hospitalization to date was 24.32 ± 30.64 days. Infectious complications were observed in 92 patients (68.7%), 76 (56.7%) of whom met the criteria for infection of the burned area, 26 patients (19.4%) for bloodstream infection, 21 (15.7%) for pneumonia, and 13 (9.7%) for urinary system infection. Multifocal infections were found in 29 patients (21.6%). Gram-positive bacterial strains as potentially pathogenic microorganisms were identified in 67 patients (50.0%), Gram-negative bacterial strains in 73 (54.5%), and yeasts in 18 (13.4%) patients. Filamentous fungi were not isolated from any patient in the group. CONCLUSION: Cornerstone future standards in individual burn centers should be to monitor the occurrence of infectious complications in burn patients, prevent the spread of these complications, and report resistant pathogens. This work constitutes an important project in this area.

ABSTRACT

INTRODUCTION: The aim is to map the current situation in the surgical treatment of pancreatic cancer in the Czech Republic. This information has been obtained from surgical treatment providers using a simple questionnaire and by identifying the so called high volume centres. The information has been collected in the interest of organizing and planning research projects in the field of pancreatic cancer treatment. METHOD: We addressed centres known to provide surgical treatment of pancreatic cancer. A simple questionnaire formulated one question about the total number of pancreatic resections, also separately for the diagnoses PDAC - C25, in the last two years (2014 and 2015). Other questions focused on the use of diagnostic methods, neoadjuvant therapy, preoperative assessment of risks, the possibility of rapid intraoperative histopathology examination, Leeds protocol, monitoring of morbidity and mortality including long-term results, and the method of postoperative follow-up and treatment. ÚZIS (Institute of Health Information and Statistics of the Czech Republic) was addressed with a request to analyze the frequency of reported total numbers for DPE, LPE, TPE and to do the same with respect to diagnosis C 25 for the last two years, available for the entire Czech Republic (2013, 2014). RESULTS: Altogether 19 institutions were identified by the preceding audit, which reported more than 10 pancreatic resections annually; these institutions were addressed with the questionnaire. Sixteen institutions responded to the questions, 13 of them completely. CONCLUSION: The majority of potentially radical surgeries for PDAC in the Czech Republic are carried out at 6 institutions. All of the institutions that participated in the survey collect data about morbidity and mortality and monitor their results. KEY WORDS: pancreas cancer outcomes surgery.

ABSTRACT

BACKGROUND: This study examined the impact of breast cancer on quality of life (QOL) of Czech women by comparing the QOL of breast cancer patients with that of age-matched healthy controls. METHODS: The sample consisted of 74 breast cancer patients who filled in self-assessment questionnaires retrospectively before treatment and at the time of the study. In addition, 73 healthy controls completed the same battery of questionnaires. QOL was assessed using the Rand 36-Item Health Survey, the Life Satisfaction Questionnaire, and the Czech research version of Functional Assessment of Breast Cancer Therapy. The Wilcoxon paired test and Mann-Whitney U test were used for data analysis. RESULTS: A statistically significant decline in QOL in breast cancer patients was found for the following components: Physical Functioning (p = 0.021), Role Functioning-Physical (p < 0.001), Bodily Pain (p = 0.001), General Health (p = 0.031), Role Functioning-Emotional (p = 0.023), and Physical Well-being (p = 0.001). The only significant increase over time was observed in Social/Family Well-being (p = 0.024). For most of the components, patients showed a statistically significant lower QOL than that of healthy controls. A recent diagnosis, advanced disease stage, more comorbidities, a higher BMI, and other sociodemographic characteristics were associated with a higher incidence of a lower QOL over time. CONCLUSION: Perceived QOL decreased over time in breast cancer patients mainly in components such as physical and emotional functioning, bodily pain, and general health, with several risk factors strongly influencing this change. The QOL of patients was lower than that of the non-cancer population, indicating that subsequent care should be improved to minimize the adverse effects that breast cancer has on QOL.

ABSTRACT

BACKROUND: We aimed to determine prognosis of vitality change and functional status of breast cancer survivors after primary oncological treatment using time-related differences of elevated levels of highly sensitive proinflammatory C-reactive protein (CRP). PATIENTS AND METHODS: The test group consisted of 46 elderly breast cancer survivors (median age was 65 years) who completed Vitality Scale of Short Form 36 (SF-36) after completing treatment and another retrospectively at diagnosis. Data on tumor-related factors, treatment, and outcomes were obtained retrospectively from medical records, and linear regression analysis was performed. CRP was followed at diagnosis and one year after primary treatment. Within the scope of this study, clinically important difference in the Vitality Scale was set at five points of change. RESULTS: Results showed a statistically significant relationship between CRP change and vitality component of SF-36 change (rs = - 0.350, p = 0.023) in which a decrease in CRP inversely correlated with the quality of life component. The overall change was 1.078 of the vitality scale score (approximately 1 point) for each 1 unit decrease of CRP (1 mg/ L). Association of CRP levels (before and after treatment, its difference between these time points) with age, number of comorbidities and stage of the disease was analyzed and no statistically significant relationship was found in our study. CONCLUSION: Preliminary results suggested time-related differences in elevated CRP levels as a potentially suitable predictor for change in vitality status for long term, chronic condition for older breast cancer survivors. We suggest the interpretation schema including an understanding that CRP change of 5 mg/ L and more should be considered a potential risk factor for subsequent negative clinical outcomes.
