Epidemiology and outcomes of hospital-acquired bloodstream infections in intensive care unit patients: the EUROBACT-2 international cohort study. Intensive Care Med 2023; 49:178-190. [PMID: 36764959 PMCID: PMC9916499 DOI: 10.1007/s00134-022-06944-2] [Citation(s) in RCA: 60] [Impact Index Per Article: 60.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 11/23/2022] [Indexed: 02/12/2023]
Abstract
PURPOSE In the critically ill, hospital-acquired bloodstream infections (HA-BSI) are associated with significant mortality. Granular data are required for optimizing management, and developing guidelines and clinical trials. METHODS We carried out a prospective international cohort study of adult patients (≥ 18 years of age) with HA-BSI treated in intensive care units (ICUs) between June 2019 and February 2021. RESULTS 2600 patients from 333 ICUs in 52 countries were included. 78% HA-BSI were ICU-acquired. Median Sequential Organ Failure Assessment (SOFA) score was 8 [IQR 5; 11] at HA-BSI diagnosis. Most frequent sources of infection included pneumonia (26.7%) and intravascular catheters (26.4%). Most frequent pathogens were Gram-negative bacteria (59.0%), predominantly Klebsiella spp. (27.9%), Acinetobacter spp. (20.3%), Escherichia coli (15.8%), and Pseudomonas spp. (14.3%). Carbapenem resistance was present in 37.8%, 84.6%, 7.4%, and 33.2%, respectively. Difficult-to-treat resistance (DTR) was present in 23.5% and pan-drug resistance in 1.5%. Antimicrobial therapy was deemed adequate within 24 h for 51.5%. Antimicrobial resistance was associated with longer delays to adequate antimicrobial therapy. Source control was needed in 52.5% but not achieved in 18.2%. Mortality was 37.1%, and only 16.1% had been discharged alive from hospital by day-28. CONCLUSIONS HA-BSI was frequently caused by Gram-negative, carbapenem-resistant and DTR pathogens. Antimicrobial resistance led to delays in adequate antimicrobial therapy. Mortality was high, and at day-28 only a minority of the patients were discharged alive from the hospital. Prevention of antimicrobial resistance and focusing on adequate antimicrobial therapy and source control are important to optimize patient management and outcomes.

Abstract
Background Health workers have been at the forefront of treating and caring for patients with COVID-19. They were often under immense pressure to care for severely ill patients with a new disease, under strict hygiene conditions and with lockdown measures creating practical barriers to working. This study aims to explore the range of mental health, financial and other practical support measures that 36 countries in Europe and Canada have put in place to support health workers and enable them to do their job. Methods We use data extracted from the COVID-19 Health Systems Response Monitor (HSRM). We only consider initiatives implemented outside of clinical settings where COVID-19 patients are treated, and therefore exclude workplace provisions such as availability of personal protective equipment, working time limits or mandatory rest periods. Results We show that countries have implemented a range of measures, ranging from mental health and well-being support initiatives, to providing bonuses and temporary salary increases. Practical measures such as childcare provision and free transport and accommodation have also been implemented to ensure health workers can get to their workplace and have their children looked after. Other initiatives such as offering continuing professional development credits for knowledge learnt during the crisis were also offered in some countries, albeit less frequently. Conclusions While a large number of initiatives have been introduced, often as ad-hoc measures, their effectiveness in helping staff is unknown in most countries. The effectiveness of these initiatives should be evaluated to inform future crisis responses and strategies for health workforce development.

Abstract
SummaryIn experiments on rabbits it was shown by means of interruption and reestablishment of hepatic and renal circulation that these organs play an essential role in the regulation of the fibrinolytic system of the circulating blood. The kidneys are the source of the plasminogen activator secreted in the blood whereas the liver is responsible for the inactivation of the fibrinolytic system.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. CONCLUSIONS Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically.

Abstract
BACKGROUND There is a positive correlation between the volume of physical activity performed and the incidence of lower extremity overuse injuries. Difficulty in evaluating the amount of activity in which highly specialised military units are engaged has prevented the implementation of a strict training programme designed to minimise overuse injuries. PURPOSE To quantify the ambulatory physical activity performed by trainees during the initial training phase in a Naval Commando Unit, with a view to developing more exact physical performance guidelines for the unit and the Israel Defense Forces, in general. METHODS Twenty-four accelerometers were worn by two teams each day. Trainees were instructed to wear the device on their non-dominant wrist 24 h a day, during all types of activities. Twice a week, the devices were collected, checked for damage and recharged, and the data were transferred to a computer. RESULTS Six trainees failed to complete the 9-week training period. Of the total 1512 accelerometer-days, 1075 readings (71%) were included in the study data. Trainees ambulated on average a distance of 15.5±8.61 km/day and 95.5 km/week. Accelerometer readings (estimated distances) were averaged each week for the two teams. The total distance measured over the 9-week study period was 911.15 km in team A and 808.38 km in team B. The total distance measured in both teams was, thus, almost double the planned 440 km (p=0.001). CONCLUSIONS Trainees greatly exceeded the planned safe distance. High variability was observed between trainees from the same team.

Abstract
CD55 (decay-accelerating factor, DAF) is overexpressed in several types of cancer, including colorectal cancer. Because of its inhibitory effect on the complement system, it has been suggested as a possible target for cancer immunotherapy. However, CD55 is also expressed in normal tissues, body fluids and stroma, limiting the use of anti-CD55 therapeutic antibodies. Two novel CD55 splice variants or isoforms have recently been identified. These have been shown to contain part or all of intron 7 (CD55(int7+)), in contrast to the previously identified splice variants (CD55(wt)), which do not contain intron 7. Our aim was to determine the pattern of expression of the CD55(int7+) isoforms in normal and cancer tissues and to compare it to CD55(wt). We found that while CD55's isoforms levels vary directly, CD55(wt) is much more abundant (on average 48 times more) than CD55(int7+). Moreover, colon cancers that express high CD55(wt) mRNA levels tend to upregulate CD55(int7+) to a further extent. Finally, we compared the protein levels of CD55(int7+) to CD55(wt) by immunohistochemistry in various colorectal pathological conditions including neoplasia, and found that the levels of both isoforms were elevated in all types of colonic pathology. These results show that the levels of CD55(int7+) in normal tissue are much lower than CD55(wt), while in tumors it is restricted to the epithelial structures unlike CD55(wt). Thus, CD55(int7+) may be a more suitable target for cancer immunotherapy.

Abstract
592 Background: Patients who present with peritoneal carcinomatosis (PC) from colorectal cancer are considered terminal, with an expected median survival of 6-8 months. Therapy is often considered palliative and aggressive treatments are nihilistically ignored. This study investigates the clinicopathologic characteristics and clinical outcomes of CRC patients who present with PC. Methods: This is a retrospective review of all patients who presented with stage IV CRC from 1/2000-12/2008 to a single, tertiary care institution. Patients with PC at the time of presentation were identified. Demographic data, clinicopathologic characteristics, treatment and survival data were collected and analyzed. Results: 591 patients who presented with stage IV colorectal cancer were identified. Complete data was available on 216 patients. PC was confirmed in 106 patients (17.9%). PC was the only site of metastatic disease in 40 patients (6.7%). Compared with patients who did not have PC, patients with PC had significantly more right-sided primary tumors (28% vs 47%) and more mucinous tumors (7% vs 22%). The median overall survival for patients with isolated PC was 11.1 months as compared with 9.1 months for PC patients with extraperitoneal metastases (p = 0.5). Conclusions: Patients with right-sided and mucinous primary colon cancers are at increased risk of developing PC. Despite a lack of aggressive therapy, patients with isolated PC achieved a 11 month median survival. Treating PC patients and patients at-risk for PC with optimal oncologic therapy, including cytoreduction and intraperitoneal chemotherapy, will improve survival and should be considered early in the management of PC patients. No significant financial relationships to disclose.

Abstract
Abstract. The fatty acid composition of meat and subcutaneous adipose tissue of the indigenous Slovenian pig breed (Krškopolje, KP), which is raised extensively, was compared with that of commercial fatteners (CP) from intensive farms. Commercial fatteners were divided into three groups according to lean meat percentage: meaty, normal and fatty. The m. longissimus dorsi of Krškopolje pigs contained less C18:0 fatty acids than that of commercial fatteners and less C16:0 than that of the fatty group. The proportions of long chain fatty acids C20:4 n-6, C20:5 n-3 and C22:5 n-3 in the Krškopolje pigs and fatty groups were also significantly different. The highest proportion of essential C18:2 n-6 and C18:3 n-3 fatty acids were found in the meaty and normal groups. Intramuscular fat content of the m. longissimus dorsi did not differ between the Krškopolje pigs, and the fatty and normal groups. The Krškopolje pigs had the lowest proportion of saturated fatty acids (SFAs), while both the Krškopolje pigs and the fatty group have a lower proportion of polysaturated fatty acids (PUFAs) than the meaty group. The fatty group had a lower polyunsaturated : saturated fatty acid ratio than the meaty and normal groups. In the subcutaneous adipose tissue, Krškopolje pigs had the highest proportion of C18:1 n-9 and differed from the normal group in C18:0 content, from the fatty group in C16:1 n-7 and from the meaty and fatty groups in C18:2 n-6. Furthermore, the Krškopolje pigs had the highest monounsaturated fatty acids (MUFAs), and lower PUFAs and n-6 PUFAs proportions than the fatty group. The meaty group had a higher n-6 : n-3 PUFA ratio than the Krškopolje pigs.

Abstract
BACKGROUND AND OBJECTIVE Methodological variability in the assessment of white matter hyperintensities (WMH) in dementia may explain inconsistent reports of its prevalence and impact on cognition. We used a method of brain MRI segmentation for quantifying both tissue and WMH volumes in Alzheimer's disease (AD) and examined the association between WMH and structural and cognitive variables. METHODS A consecutive series of 81 patients meeting NINCDS-ADRDA criteria for probable AD was studied. Nineteen healthy volunteers of comparable age served as the control group. Patients had a complete neurological and neuropsychological evaluation, and a three dimensional MRI was obtained. Images were segmented into grey matter, white matter, and cerebrospinal fluid. WMH were edited on segmented images, and lobar assignments were based on Talairach coordinates. RESULTS Mild and moderate to severe AD patients had significantly more WMH than controls (p<0.05). WMH preferentially involved the frontal lobes (70%), were inversely correlated with grey matter cortical volume (R(2) = 0.23, p<0.001), and were significantly associated with vascular risk factors and with a worse performance on memory tasks. CONCLUSION Objective measurements of tissue volumes in AD demonstrated that WMH are significantly related to cortical atrophy and neuropsychological impairment.

Abstract
Protein undernutrition inhibits adenosine triphosphate (ATP)-dependent muscle protein degradation-a hallmark of the proteasome system. Here we report decreased myofibrillar protein degradation during dietary protein restriction without a concomitant decrease in proteasome gene expression, proteasome protein abundance, or proteasome in vivo fractional synthesis rate. Healthy human subjects consuming the average minimum adult protein requirement (0.71 g x kg(-1) fat-free mass x d(-1)) exhibited substantially lower (68%) excretion of 3-methylhistidine, an indicator of myofibrillar protein breakdown, when compared with subjects consuming an ample, American-style protein intake (1.67 g x kg(-1) fat-free mass x d(-1)). However, they displayed no difference in the expression of mRNA for proteasome subunits C2 or C3, in the content of C2 protein, or in the rate of incorporation of stable isotopically labeled l-[1-(13)C]-leucine into proteasome proteins. The results demonstrate that nutritional inhibition of myofibrillar protein degradation does not involve suppression in vivo of proteasome production in man. This suggests that other elements of the ubiquitin-proteasome system, such as ubiquitination pathways, are more important than proteasome abundance in the nutritional regulation of skeletal muscle mass.

Abstract
The potential for emergence of resistance to biocides has been a concern in recent years. This study tested whether an association exists between the intensity of chlorhexidine use and chlorhexidine susceptibility of micro-organisms isolated from patients in different clinical areas in an acute-care general hospital. Organisms frequently involved in nosocomial infections in the hospital were chosen for study over a six week period: Staphylococcus aureus (60 isolates), coagulase-negative staphylococci (48), Klebsiella pneumoniae (32), Pseudomonas aeruginosa (60), Acinetobacter baumannii (16) and Candida albicans (35). An index of chlorhexidine exposure for each clinical unit was derived for the year preceding organism collection. Chlorhexidine susceptibility was evaluated using agar incorporation minimum inhibitory concentrations (MICs) and disk diffusion. A statistically significant inverse correlation was shown between intensity of chlorhexidine use and the overall susceptibility of all study organisms taken together. There was no association when individual taxa were considered. These findings must be interpreted with caution considering that greater use of chlorhexidine is likely to occur in difficult clinical disciplines where antibiotic use, invasive procedures and other intensive care-related procedures, cross-infection and immunosuppression are all potential confounding factors. There was an excellent correlation between MICs and disk testing, suggesting that disk diffusion might be useful in studies involving more than one biocide.

Abstract
Rats exposed to a novel environment just prior to or 1-2 h, but not 4 or 6 h, before retention testing exhibited an enhanced retrieval of a one-trial inhibitory avoidance training. The bilateral intrahippocampal infusion of PD098059, an inhibitor of mitogen-activated protein kinase (MAPK), the specific upstream activator of p42 and p44 MAPKs, given 10 min before the exposure to the novel environment, blocked the enhancing effect of novelty on memory retrieval. In addition, prenovelty infusion of DL-2-amino-5-phosphonovalerate (APV), an antagonist of glutamate NMDA receptors, produced similar effects. The exposure to the novel environment is associated with an activation of p42 and p44 MAPKs and an increase in the phosphorylation state of the transcription factor cAMP response element binding protein (CREB). No changes were observed in cAMP-dependent protein kinase (PKA) activity or in alpha-CAMKII activation. Taken together, our results indicate that novelty activates hippocampal MAPKs, which are necessary, along with glutamate NMDA receptors, for the enhancing effect of novelty on retrieval.

Abstract
From mollusks to mammals the activation of cAMP response element-binding protein (CREB) appears to be an important step in the formation of long-term memory (LTM). Here we show that a 5 min exposure to a novel environment (open field) 1 hr after acquisition of a one-trial inhibitory avoidance training hinders both the formation of LTM for the avoidance task and the increase in the phosphorylation state of hippocampal Ser 133 CREB [phosphorylated CREB (pCREB)] associated with the avoidance training. To determine whether this LTM deficit is attributable to the reduced pCREB level, rats were bilaterally cannulated to deliver Sp-adenosine 3', 5'-cyclic monophosphothioate (Sp-cAMPS), an activator of PKA. Infusion of Sp-Adenosine 3',5'-cyclic monophosphothioate Sp-cAMPS to CA1 region increased hippocampal pCREB levels and restored normal LTM of avoidance learning in rats exposed to novelty. Moreover, a 5 min exposure to the open field 10 min before the avoidance training interferes with the amnesic effect of a second 5 min exposure to the open field 1 hr after avoidance training and restores the hippocampal levels of pCREB. In contrast, the avoidance training-associated activation of extracellular signal-regulated kinases (p42 and p44 mitogen-activated protein kinases) in the hippocampus is not altered by novelty. Together, these findings suggest that novelty regulates LTM formation by modulating the phosphorylation state of CREB in the hippocampus.

Abstract
Long-term habituation to a novel environment is one of the most elementary forms of nonassociative learning. Here we studied the effect of pre- or posttraining intrahippocampal administration of drugs acting on specific molecular targets on the retention of habituation to a 5-min exposure to an open field measured 24 h later. We also determined whether the exposure to a novel environment resulted in the activation of the same intracellular signaling cascades previously shown to be activated during hippocampal-dependent associative learning. The immediate posttraining bilateral infusion of CNQX (1 microg/side), an AMPA/kainate glutamate receptor antagonist, or of muscimol (0.03 microg/side), a GABA(A) receptor agonist, into the CA1 region of the dorsal hippocampus impaired long-term memory of habituation. The NMDA receptor antagonist AP5 (5 microg/side) impaired habituation when infused 15 min before, but not when infused immediately after, the 5-min training session. In addition, KN-62 (3.6 ng/side), an inhibitor of calcium calmodulin-dependent protein kinase II (CaMKII), was amnesic when infused 15 min before or immediately and 3 h after training. In contrast, the cAMP-dependent protein kinase (PKA) inhibitor Rp-cAMPS, the mitogen-activated protein kinase kinase (MAPKK) inhibitor PD098059, and the protein synthesis inhibitor anisomycin, at doses that fully block memory formation of inhibitory avoidance learning, did not affect habituation to a novel environment. The detection of spatial novelty is associated with a sequential activation of PKA, ERKs (p44 and p42 MAPKs) and CaMKII and the phosphorylation of c-AMP responsive element-binding protein (CREB) in the hippocampus. These findings suggest that memory formation of spatial habituation depends on the functional integrity of NMDA and AMPA/kainate receptors and CaMKII activity in the CA1 region of the hippocampus and that the detection of spatial novelty is accompanied by the activation of at least three different hippocampal protein kinase signaling cascades.

Abstract
We investigated the association of p53 abnormalities (gene mutations by DNA sequencing and protein over-expression by immunostaining) with clinical data and prognosis in 74 patients with resected non-small cell lung cancer (NSCLC). DNA analysis of exons 5-8 of the p53 gene showed 34 mutations in 74 resected primary NSCLC (45.9%). Immunohistochemical study of the p53 protein revealed that 41 of 74 (55.4%) samples had positive staining. We found strong agreement between the results of the p53 protein expression test (p53-PE) and the p53 gene mutation test (p53-M) (Cohen's kappa = 0.65, 95% CI 0.48-0.82). Joint distribution of the results (analysed using the bivariate Dale model) was mainly influenced by, histological type of tumour. A positive result for the p53-PE test significantly increased (estimated odds ratio 84.5; 95% CI 8.89-803.03) the odds of observing a positive result in the p53-M test. In the univariate analysis (log rank test), positive results in the p53-M test and the p53-PE test were significantly associated with overall survival (P < 0.001 and P = 0.005, respectively). In the multivariate analysis (Cox's proportional hazard model), a positive result for the p53-M test significantly increased relative risk for overall survival (RR 9.56; 95% CI 2.62-34.87; P < 0.001). When the result of the p53-M test was accounted for, a positive result for the p53-PE test did not offer any additional prognostic information due to the strong dependence of results of the tests. However, when the result of the p53-M test was removed from the model, a positive result for the p53-PE test became a significant unfavourable prognostic factor (P = 0.009). We conclude that p53 gene mutation and protein expression analyses are in a strong agreement. Joint distribution of the results depends mainly on histological type of tumour. When considered separately, both tests are unfavourable prognostic factors in NSCLC. When the result of the p53-M test is taken into account, the p53-PE test does not offer any additional prognostic information.

Abstract
Several evidences demonstrate that protein kinase C (PKC) is involved in hippocampal long-term potentiation (LTP) and in different forms of learning, including inhibitory avoidance training in rats. Here, we evaluated the levels of conventional PKC isozymes (alpha, betaI, betaII, gamma) in synaptic plasma membrane (SPM) fractions isolated from hippocampus of rats subjected to a one-trial inhibitory avoidance paradigm. At 0, 30 and 120 min after training, there was a significant increase in the total amount of PKCbetaI. Densitometric analysis of the immunoblots showed an increase of 142+/-11% at 0 min, 193+/-16% at 30 min and 156+/-6% at 120 min after training relative to shocked control values. No changes were found in PKCbetaI levels in SPM fractions of the shocked animals relative to naive control values. No training-specific increments in the levels of PKCalpha, betaII and gamma were observed at any time point tested. However, an increase in PKCgamma levels was found in trained and shocked animals sacrificed 120 min after each experimental procedure. In addition, bilateral microinjections of a fairly selective inhibitor of PKCbetaI isozyme into the CA1 of the dorsal hippocampus produced amnesia when given 10 min before training, or 50, 110, but not 170 min, after training. Thus, the present findings demonstrate the participation of PKCbetaI in the early synaptic events responsible for the acquisition and consolidation of an inhibitory avoidance learning, and suggest a putative role of this presynaptic isozyme on the enhanced PKC-dependent B-50/GAP-43 phosphorylation previously detected by us during this associative learning.

Abstract
Molecular genetic studies have revealed mutations in a number of oncogenes and tumor suppressor genes in lung cancer. The bcl-2 gene product (bcl-2 protein) is implicated in oncogenesis by its ability to prolong cell death through the inhibition of apoptosis. We investigated expression of bcl-2 in 84 resected human non-small cell lung cancers (NSCLC) and correlated this phenomena with clinicopathology and survival. Immunohistochemical analysis with a monoclonal antibody specific for bcl-2 (Clone 124; Dako) was used to detect the protein in tumor samples. Overall, bcl-2 was detectable in 39 of 84 (46%) NSCLC. The percentage of bcl-2 positive cases varied according to the histological type. Positive bcl-2 immunostaining was observed in 27 of the 46 squamous cell carcinomas (59%), 7 of the 25 adenocarcinomas (28%) and 5 of the 13 large cell carcinomas (38%). The frequency of positive bcl-2 expression in squamous cell carcinomas was significantly higher than that in other histological two types (p = 0.037). Statistical comparisons between the patients' clinical characteristics and bcl-2 status revealed no significant differences in the frequency of bcl-2 expression with respect to sex, T and N factors, as well as TNM stage. The relationship between bcl-2 protein expression and postoperative survival was analyzed in 84 patients. Patients with bcl-2 negative tumors showed significantly shorter survival times than those with bcl-2 positive tumors. In univariate analysis of various potential prognostic factors only TNM stage and bcl-2 test were significant prognostic factors (p < 0.009 and p < 0.008, respectively). In multivariate analysis (Cox proportional hazard model), bcl-2 status (negative test) was independent unfavorable prognostic factor (p = 0.017). In conclusion, this set of observations suggests that assessment of the expression status of bcl-2 by tumors may provide prognostic information on the clinical behavior of NSCLC.

Abstract
Cytokeratin 19 is particularly abundant in carcinoma of the lung. The CYFRA 21-1 assay has recently been developed for detection of a cytokeratin 19 fragment in serum. In the current study, the prognostic information provided by the CYFRA 21-1 assay in operable nonsmall cell lung cancer (NSCLC) was analysed. Serum levels of CYFRA 21-1 were measured using an immunoradiometric assay (DiaSorin) in 94 patients with operable NSCLC. Survival and disease-free survival curves related to initial levels of this marker were estimated using the Kaplan-Meier method. Elevated preoperative CYFRA 21-1 levels were identified in 42% of patients with NSCLC. The number of patients with elevated levels of this marker increased with tumour node metastasis (TNM) stage (p=0.02). In univariate analysis elevated levels of CYFRA 21-1 were significantly associated with poor overall survival (p<0.001) and with disease-free survival (p<0.001). The results remained significant when the comparisons were adjusted, using the stratified log-rank test, for patient's TNM stage (p<0.001 for both overall and disease-free survival). Elevated preoperative levels of CYFRA 21-1 decreased the probability of survival or surviving without recurrence 15 months or more after the operation. This was confirmed by the results of the multivariate analysis. In conclusion, CYFRA 21-1 may be an independent prognostic parameter of survival and tumour relapse in nonsmall cell lung cancer and may be useful in identifying resected cancer patients at high risk for treatment failure.

Abstract
BACKGROUND Serum antibodies against p53 protein (p53-Abs) have been detected in some cancer patients. The significance and use of p53-Abs as a marker of the clinical behavior of lung cancer is currently under investigation. PURPOSE In this study, we measured the serum p53-Abs in 84 patients with operable non-small cell lung cancer (NSCLC) and evaluated potential association between the presence of these antibodies and prognosis. METHODS Enzyme-linked immunosorbent assay (ELISA) was used to detect p53-Abs in serum. Survival and disease-free survival curves related to initial p53-Abs status were estimated using the Kaplan-Meier method. RESULTS At the time of diagnosis 19 (22.6%) of 84 analyzed patients had positive result from the serum p53 antibodies (p53-Abs) test. No association was found between p53-Abs, histological types of tumors and clinical stage of disease. We found that patients with a positive result from the p53-Abs test had lower probability of overall and disease-free survival. The unfavorable effect was significant both in the univariate analysis, as well as in the multivariate analysis (after adjustment for sex, histopathological type of tumor. TNM stage). CONCLUSION The results of the present study indicate that serum p53 antibodies may be an independent prognostic factor in NSCLC, especially in the squamous cell carcinoma (SqCC) patients and may be useful in identifying resected lung cancer patients at high risk for treatment failure.
