[Expenditure on the Care of COPD Patients Under Everyday Conditions in Pneumological Practices Differentiated According to Patients in Chronic Care and New Patients and Severity of the Illness]. / Aufwand bei der Betreuung von COPD-Patienten unter Alltagsbedingungen in pneumologischen Praxen differenziert nach bekannten und neuen Patienten und nach Schweregraden der Erkrankung.

New patients in the secondary respiratory care require more time for the first consultation and place a higher diagnostic and therapeutic demand if compared to patients already in chronic care. More diagnostic procedures and patient's education by the team are required. No such burden is observed regarding differential degrees of severity of respiratory diseases, e. g. COPD. The overall demands add up to twice the demands of patients already in care. Thus the time required for the treatment of 50 new patients allows consultations for 100 patients already known in the office.As additional time and effort for new patients is not adequately represented in the German medical tax (EBM) a trend to risk selection and a preference for control patients is observed. In contrast incentives to foster treatment of new patients could be an effective measure to dramatically reduce waiting time for visits with pulmonologists. This should be achieved by changes in the German medical tax (EBM).

[Positionpaper on Telemonitoring in Sleep-Related Breathing Disorders]. / Positionspapier zum Telemonitoring bei schlafbezogenen Atmungsstörungen.

The use of telemonitoring in the care of patients with Sleep-related Breathing Disorders (SBD) can enhance medical support significantly. Telemonitoring aims at helping physicians to detect therapy problems early and thus improve patients' therapy adherence. Diagnostics and therapy decisions in the telemonitoring process nevertheless remain the responsibility of sleep specialists. The selection of data monitored, their evaluation and resulting consequences fall to the physician, who makes decisions and prescribes therapy in consultation with the patient. In light of professional legal and ethical requirements, it must be ensured that the extensive changes to the process flow in sleep medicine are designed in a way to guarantee high-quality patient care. In this position paper, the German Sleep Society, the German Respiratory Society, the Association of Pneumological Hospitals and the Federal Association of German Pneumologists comment on important aspects for implementation of telemonitoring for SRBD and describe the basic conditions required for its use.

The effect of peer review on mortality rates.

OBJECTIVE: Lowering of mortality rates in hospitals with mortality rates higher than accepted reference values for acute myocardial infarction (AMI), congestive heart failure (CHF), pneumonia, stroke, mechanical ventilation (MV) and colorectal surgery by using an external peer review process that identifies areas requiring rectification and implements protocols directed at improving these areas. DESIGN: Retrospective, observational, quality management study using administrative data to compare in-hospital mortality rates (pre and post an external peer review process that included adoption of improvement protocols) with reference values. SETTING: German general hospitals of a large, private group. PARTICIPANTS: Hospitals with mortality rates higher than reference values. INTERVENTIONS: Peer review of medical records by experienced, outside physicians triggered by in-hospital mortality rates higher than expected. Inadequacies were identified, improvement protocols enforced and mortality rates subsequently re-examined. MAIN OUTCOME MEASURES: Mortality rates 1 year before and 1 year after peer review and protocol use. RESULTS: For AMI, CHF, pneumonia, stroke, MV and colorectal surgery, the mortality rates 1 year post-peer review were significantly decreased as compared to pre-peer review mortality rates. The standardized mortality ratio for all of the above diagnoses was 1.45, 1 year before peer review, and 0.97, 1 year after peer review. The absolute risk reduction of 7.3% translates into 710 deaths in this population which could have been prevented. CONCLUSIONS: Peer review triggered and conducted in the manner described here is associated with a significant lowering of in-hospital mortality rates in hospitals that previously had higher than expected mortality rates.

[Cannabis--Position Paper of the German Respiratory Society (DGP)]. / Cannabis--Positionspapier der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin e.V. (DGP).

In this position paper, the adverse health effects of cannabis are reviewed based on the existing scientific literature; in addition possible symptom-relieving effects on some diseases are depicted. In Germany, cannabis is the most widely used illicit drug. Approximately 600,000 adult persons show abusive or addictive cannabis consumption. In 12 to 17 year old adolescents, cannabis use increased from 2011 to 2014 from 2.8 to 6.4%, and the frequency of regular use from 0.2 to 1.5%. Currently, handling of cannabinoids is much debated in politics as well as in general public. Health aspects have to be incorporated into this debate. Besides analysing mental and neurological side effects, this position paper will mainly focus on the influences on the bronchopulmonary and cardiovascular system. There is strong evidence for the induction of chronic bronchitis. Allergic reactions including asthma are known, too. Associations with other diseases like pulmonary emphysema, lung cancer and pneumonia are not sufficiently proven, however cannot be excluded either. In connection with the use of cannabis cardiovascular events such as coronary syndromes, peripheral vascular diseases and cerebral complications have been noted. Often, the evidence is insufficient due to various reasons; most notably, the overlapping effects of tobacco and cannabis use can frequently not be separated adequately. Empirically, early beginning, high-dosed, long-lasting and regular cannabis consumption increase the risk of various psychological and physical impairments and negatively affect age-based development. Concerns therefore relate especially to children and adolescents. There is only little scientific evidence for medical benefits through cannabis as a remedy; systematic research of good quality, in particular prospective, randomised, placebo-controlled double-blinded studies are rare. The medical societies signing this position paper conclude that cannabis consumption is linked to adverse health effects which have to be taken into consideration in the debate about the social attitude towards cannabinoids. The societies agree that many aspects regarding health effects of cannabis are still uncertain and need clarification, preferably through research provided by controlled studies.

[Daily care of patients with asthma in the pulmonary practice: changes in asthma - control and therapy depending on the initial level of control]. / Alltagsversorgung von Patienten mit Asthma in der pneumologischen Praxis: Veränderungen des Asthma-Kontrollgrades und der Therapie in Abhängigkeit vom ursprünglichen Kontrollgrad.

To assess the quality of treatment of patients with asthma who were treated jointly by pulmonologists and the family doctor, a data analysis was performed in 13 asthma specialists in 894 asthmatics and a written survey of patients after 3 months of treatment.The data analysis related to the current therapy, the therapy changes and the changes in asthma control test (ACT). One focus of the investigation was placed on the separate analysis of patients with controlled and uncontrolled asthma. Both patient groups show both decrease, as well as increases in the number of points of the ACT. In patients with non-controlled asthma, the proportion of an increase in the number of points in the ACT is above average and indicates an improvement of the disease. This is operated in the patient's subjective assessment. In both patient groups there is a large proportion of patients who report a subjective improvement. An improvement is usually achieved by an improved pharmacotherapy, a deterioration usually occurs due to external influences. The differences for the patient groups are here but less significantly. There is a general satisfaction with both the drug therapy, as well as with the handling. The inhalation drug therapy is performed very stable. In patients with poor asthma control therapy is usually intensified. In oral pharmacotherapy oral steroid therapy has a great dynamic in patients with uncontrolled asthma. In this group, the most frequent increases in the dose of inhaled substances are recorded.

[Therapy adherence in bronchial asthma patients: Healthcare under everyday conditions in pulmonological practices]. / Therapieadhärenz bei Asthma bronchiale - Versorgung unter Alltagsbedingungen in der pneumologischen Praxis.

In the present study, patients with asthma were interviewed with regard to their treatment adherence. It was shown that adherence is significantly influenced by age, occupation, quality of information about the disease and interest of the patient in disease, mode of action and use of the inhalation device. Younger, working patients who do not feel "completely adequately" informed are more likely to be not-adherent. Each aspect should be noted separately.The characterization enables forming target groups for appropriate counselling initiatives in pulmonology practice and allows the effectiveness of the measures to be examined. The results confirm the importance of doctor/patient communication for achieving a high level of adherence and thus therapeutic success.It is suggested that, in addition to questionnaires already in use, asthma patients should be given the following questions in writing during routine monitoring of therapy; based on the results of the survey, the extent of advice necessary can be determined -Do you feel sufficiently informed about your illness? -Do you feel sufficiently informed about the effect of the drug therapy? -Do you feel sufficiently informed about the handling of the inhalation drugs? -Are you satisfied with the handling of your inhalation medication? The following options to answer the questions should be available: completely - mainly - somewhat - not at all. There were significant differences in adherence between patients who were completely satisfied with the handling of their device and those that were not. However, there was no significant difference between the devices. Therefore, the same therapy adherence can be predicted for all devices when the device is suitable for the patient and also provides complete satisfaction in handling. Since it is the subjective perception of patients, the data show significant differences between study centres. These were mirrored in a blind benchmark to stimulate improvements.

Identification of prognostic factors predicting outcome in Hodgkin's lymphoma patients relapsing after autologous stem cell transplantation.

BACKGROUND: High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is the standard of care for patients with relapsed Hodgkin's lymphoma (HL). However, there is currently little information on the predictors of outcome for patients whose disease recurs after ASCT. METHODS: Five hundred and eleven adult patients with relapsed HL after ASCT from EBMT-GITMO databases were reviewed. RESULTS: Treatments administered following ASCT failure included conventional chemotherapy and/or radiotherapy in 294 (64%) patients, second ASCT in 35 (8%), and alloSCT in 133 (29%). After a median follow-up of 49 months, overall survival (OS) was 32% at 5 years. Independent risk factors for OS were early relapse (<6 months) after ASCT, stage IV, bulky disease, poor performance status (PS), and age ≥50 years at relapse. For patients with no risk factors OS at 5 years was 62% compared with 37% and 12% for those having 1 and ≥2 factors, respectively. This score was also predictive for outcome in each group of rescue treatment after ASCT failure. CONCLUSION(S): Early relapse, stage IV, bulky disease, poor PS, and age ≥50 years at ASCT failure are relevant factors for outcome that may help to understand the results of different therapeutic approaches.

IL-10 promoter polymorphisms influence susceptibility to aGvHD and are associated with proportions of CD4+FoxP3+ lymphocytes in blood after hematopoietic stem cell transplantation.

Four hundred and ninety-five patients (390 and 105 grafted from unrelated and sibling (SIB) donors, respectively) and their donors were analyzed for the impact of interleukin-10 (IL-10) promoter genotype [rs18000896 (-1082 G/A), rs18000871 (-819 C/T) and rs18000872 (-592 C/A)] on the outcome of hematopoietic stem cell transplantation (HSCT). Patients having ACC haplotype were at a lower risk of acute graft versus host disease (aGvHD, grade > I) if transplanted from human leukocyte antigen (HLA) well-matched (10/10) unrelated donors (20/135 vs 39/117, P < 0.001, Pcorr = 0.002), which was not seen if patients were transplanted from either sibling (SIB) or poorly matched (<10/10) unrelated donors (MUD). In addition, GCC haplotype positive recipients of unrelated donor transplants tended to be more susceptible to aGvHD (68/199 vs 39/169, P = 0.019, Pcorr = 0.057). Multivariate logistic regression analysis in the MUD transplanted group showed that donor-recipient human leukocyte antigen (HLA) mismatch [odds ratio (OR) = 3.937, P = 0.001] and a lack of ACC haplotype in recipients (OR = 0.417, P = 0.013) played a significant role as independent risk factors of aGvHD grade > I. ACC carriers had higher proportions of FoxP3+ lymphocytes gated in CD4+ lymphocytes as compared with patients with other IL-10 haplotypes. It was seen at the time of hematological recovery (mean ± SEM: 3.80 ± 0.91% vs 2.06 ± 0.98%, P = 0.012) and 2 weeks later (5.32 ± 0.87% vs 2.50 ± 0.83%, P = 0.013); -592 C/A polymorphism was separately analyzed and it was found that AA homozygotes tended to have a higher incidence of aGvHD (8/15 vs 116/456, P = 0.034) and low proportions of FoxP3 CD4+ lymphocytes in blood (0.43 ± 0.22% vs 4.32 ± 0.71%, P = 0.051) measured 2 weeks after hematological recovery. Functional IL-10 polymorphism associated features influenced the risk of aGvHD with a positive effect of ACC on the pool of Treg in blood.

Leukemia and risk of recurrent Escherichia coli bacteremia: genotyping implicates E. coli translocation from the colon to the bloodstream.

In patients with leukemia, the portal(s) and reasons for the persistence of an Escherichia coli recurrent bacteremia remain unclear. Adult Hematology Clinic (AHC) databases at the State Clinical Hospital in Gdansk were reviewed to evaluate the frequency of E. coli bacteremia between 2002 and 2005. Blood and bowel E. coli strains were obtained and the genetic relatedness of the strains was analyzed. The rate of E. coli bacteremia per 1,000 admissions at the AHC was higher (85.0) than in the other clinics of the hospital (2.9), p < 0.001. A higher mortality was observed in patients with a history of E. coli versus non-E. coli bacteremia [30/95 (31 %) vs. 53/430 (12 %), p < 0.001]; 72.8 % of patients with leukemia had an unknown source of bacteremia. In 2005, 6 out of 25 (24 %) patients with leukemia had ≥2 episodes of E. coli-positive blood cultures. These gastrointestinal E. coli isolates were replaced within 3-8 weeks with a new E. coli H genotype. A recurrent episode of bacteremia was usually caused by an infection with a transient E. coli H genotype identical to that found in the subject's bowel. Consistent with the definition of bowel/blood translocation, the bowel appeared to be a portal for E. coli in these subjects and, hence, a clear source for their recurring bacteremia.

Experience with Optivate®, a new high purity concentrate of factor VIII with von Willebrand factor, in patients undergoing surgery.

The efficacy and safety of Optivate(®) was assessed in 23 surgical operations, orthopaedic (12) including 5 revision arthroplasties, ophthalmic (1), ENT (1), dental (6), liver biopsy (2), and removal of portacath (1) on 15 teenagers and adults with severe haemophilia A. The preoperative dose was calculated to raise the FVIII concentration to 100 IU dL(-1). Subsequent doses were targeted to maintain at least 50 IU dL(-1). There were 11 major and 12 minor operations categorized as receiving intensive replacement therapy for ≥ 5 days or < 5 days respectively. The median preoperative dose was 50.4 (range 18.2-88.2) IU kg(-1). The median incremental recovery based on this first dose in 10 procedures (5 patients) was 2.9 (range 2.4-3.4 IU dL(-1) ) per IU kg(-1). The daily doses decreased during the first 4 days of the study. The patients in this study received 173 infusions in total. Outcome was 'good' or 'excellent' for 19 (83%) of 23 operations, 'uncertain' in three procedures because an antifibrinolytic agent was used as well and for one procedure outcome was not assessed. Tolerance was good. There were no excessive bleeds, no inhibitors and no virus transmissions.

Clinical assessment of Optivate®, a high-purity concentrate of factor VIII with von Willebrand factor, in the management of patients with haemophilia A.

Factor VIII (FVIII) concentrates have revolutionized the treatment of patients with haemophilia A. Concerns over the transmission of viral infections through these products have been addressed through stringent, donor-screening procedures and robust antiviral manufacturing steps. Bio Products Laboratory has developed a high-purity FVIII product with von Willebrand factor, Optivate(®). Its safety, tolerability and efficacy as prophylaxis and treatment of bleeds have been established in long-term studies. Seventy previously treated patients with severe haemophilia A, with ≥ 20 exposure days, were recruited into two long-term, multicentre, open-label studies. The protocols were virtually identical. Patients received Optivate(®) either prophylactically or on-demand. A mean of 159.0 EDs were experienced over 11,320 infusions. Under both conditions, Optivate(®) was well tolerated. Only 10% of patients experienced a treatment-related adverse event; the most commonly reported were headache (4% of patients) and dizziness (3% of patients). The mean number of bleeds/patient over the 2 year treatment period was 23.5 during prophylactic use and 70.4 during on-demand use. In patients treated prophylactically, clinical responses to breakthrough bleeds were rated by physicians as excellent or good and as very helpful or helpful by patients in 95% of bleeds. Clinical responses for on-demand patients were rated as excellent or good by physicians and helpful or very helpful by the patients for 91% of bleeds. There were no viral transmissions or inhibitors. The studies confirm the clinical efficacy and safety of Optivate(®) in both prophylactic and on-demand management of patients with haemophilia A.

Pharmacokinetics of Optivate(®), a high-purity concentrate of factor VIII with von Willebrand factor, in patients with severe haemophilia A.

Optivate(®) is a high purity factor VIII/von Willebrand factor (FVIII/VWF) concentrate, which is manufactured using two antiviral processes: solvent/detergent and terminal dry heating (80 °C for 72 h). A multicentre, non-randomized open-label study in 15 patients was conducted to test the pharmacokinetics (PK) of Optivate(®). PK variables were analysed for the patients' prior FVIII product (PK1), their first dose of Optivate(®) (PK2) and at 3 months therapy (PK3). Mean non-compartmental half-lives (h) were 14.1, 12.4 and 12.1, respectively (P = 0.45), mean clearances (mL h(-1) kg(-1)) were 3.6, 3.2 and 3.1, respectively (P = 0.051), MRTs (h) were 19.0, 17.3 and 17.4, respectively (P = 0.39) and mean AUC(0-48h) (h IU mL(-1)) were 14.3, 15.4 and 16.6, respectively (P = 0.051) and mean AUC(0-∞) (h IU mL(-1)) were 15.9, 16.4 and 17.9, respectively (P = 0.18). The recovery data from this PK study was aggregated with recovery data collected from another study, with similar design but devoid of the other PK measurements. A total of 309 recoveries were conducted in 70 patients. The overall mean recovery per subject across 27 Optivate(®) batches was 2.7 IU dL(-1) per IU kg(-1). There were no clinical differences between Optivate(®) and other FVIII products, and except for volume of distribution (Vd), no statistically significant differences were seen with respect to any of the other PK variables, or in recovery between weeks 0 and 12. Therefore, the PK of FVIII is not affected by the processes used to manufacture Optivate(®), which can be expected to be effective in the management of patients with haemophilia A.

International registry on the use of the CytoSorb® adsorber in ICU patients : Study protocol and preliminary results.

INTRODUCTION: The aim of this clinical registry is to record the use of CytoSorb® adsorber device in critically ill patients under real-life conditions. METHODS: The registry records all relevant information in the course of product use, e. g., diagnosis, comorbidities, course of the condition, treatment, concomitant medication, clinical laboratory parameters, and outcome (ClinicalTrials.gov Identifier: NCT02312024). Primary endpoint is in-hospital mortality as compared to the mortality predicted by the APACHE II and SAPS II score, respectively. RESULTS: As of January 30, 2017, 130 centers from 22 countries were participating. Data available from the start of the registry on May 18, 2015 to November 24, 2016 (122 centers; 22 countries) were analyzed, of whom 20 centers from four countries provided data for a total of 198 patients (mean age 60.3 ± 15.1 years, 135 men [68.2%]). In all, 192 (97.0%) had 1 to 5 Cytosorb® adsorber applications. Sepsis was the most common indication for CytoSorb® treatment (135 patients). Mean APACHE II score in this group was 33.1 ± 8.4 [range 15-52] with a predicted risk of death of 78%, whereas the observed mortality was 65%. There were no significant decreases in the SOFA scores after treatment (17.2 ± 4.8 [3-24]). However interleukin-6 levels were markedly reduced after treatment (median 5000 pg/ml before and 289 pg/ml after treatment, respectively). CONCLUSIONS: This third interim report demonstrates the feasibility of the registry with excellent data quality and completeness from 20 study centers. The results must be interpreted with caution, since the numbers are still small; however the disease severity is remarkably high and suggests that adsorber treatment might be used as an ultimate treatment in life-threatening situations. There were no device-associated side effects.

Ureteric Stenting in Kidney Transplant Recipients, Gdansk Centre Experience, Poland.

BACKGROUND: The role of ureteric stenting in kidney transplant recipients is still debatable. Stenting can reduce the incidence of urine leaks and ureter stenosis, but can be also associated with specific complications, particularly urinary tract infections (UTIs). MATERIAL AND METHODS: To estimate the influence of ureteric stenting on urological complications in kidney transplantation (KTx), we retrospectively analyzed all KTx performed between January 2011 and December 2016 in Gdansk Transplantation Centre, a total of 628 patients. Ureteric stenting was used in 502 patients (80%)-double-J (DJ) group. Catheters were implanted during the surgical procedure and left in situ for a mean time of 30 days. RESULT: The frequency of urinary leaks was 10 times higher in patients without stenting (10%). Ureter stenosis was also more frequent in the non-DJ group (8.7% vs 1.6%, P < .05). Multiple-regression modeling showed that the urinary not stenting was a risk factor for urinary leak (adjusted odds ratio [AOR] = 0,1; 95% confidence interval [CI]: 0.03-0.26; P < .01), ureter stenosis (AOR = 0,16; 95% CI: 0.06-0.41; P < .01), and generally reoperation after KTx (AOR = 0,46; 95% CI: 0.28-0.77; P < .01). Acute rejection and delayed graft function were equal in both groups. Mean serum creatinine concentration 1 month after transplantation was similar in both groups (1.5 mg/dL in the DJ group and 1.44 mg/dL in the non-DJ group, P > .05). UTIs were more frequent in the DJ group (22.1% vs 16.7%), but the difference was not significant. Time of hospitalization was longer in patients with UTI (34 vs 22 days, P < .05). CONCLUSIONS: Ureteric stenting can protect patients from most frequent urological complications like urine leaks and ureter stenosis. The influence of ureteric stenting on UTI development is not strong in our material.

Two autologous transplants in the treatment of patients with Hodgkin's lymphoma: analysis of prognostic factors and comparison with a single procedure.

We summarized registry data of the long term observation of 35 patients treated with two autologous transplants. Prognostic factors for overall survival (OS) and DFS were analyzed. The OS was compared with 105 patients from a single transplant group. Two factors were significant in univariate analysis of DFS after the second transplant: response to the first transplant (complete remission (CR) versus progressive disease (PD) p = 0.041) and the disease status at the time of the second autologous stem cell transplantation (ASCT) (CR versus partial remission (PR) p = 0.004; CR versus PD p = 0.0002). In the multivariate analysis only the last of the parameters remain significant (RR 2.30, p = 0.004, 95% CI; 1.30 - 4.04). In the analysis of OS, two factors were significant in univariate analysis: status of the disease at the first transplant (PR versus PD p = 0.008) and response to the first transplant (CR versus PD p = 0.025). None of those factors remained significant in a multivariate analysis. A probability of 5-year survival after the first transplant in patients treated with two transplants was 83% (95% CI; 70 - 97%). A tendency towards better survival was seen in patients treated with two transplants (p = 0.01). The trend toward better survival from the time of diagnosis is kept for those who entered CR or PR after standard chemotherapy (p = 0.097) but not for the whole group (p = 0.13).

Treatment-free remission following frontline nilotinib in patients with chronic myeloid leukemia in chronic phase: results from the ENESTfreedom study.

The single-arm, phase 2 ENESTfreedom trial assessed the potential for treatment-free remission (TFR; i.e., the ability to maintain a molecular response after stopping therapy) following frontline nilotinib treatment. Patients with Philadelphia chromosome-positive chronic myeloid leukemia in chronic phase with MR4.5 (BCR-ABL1⩽0.0032% on the International Scale (BCR-ABL1IS)) and ⩾2 years of frontline nilotinib therapy were enrolled. Patients with sustained deep molecular response during the 1-year nilotinib consolidation phase were eligible to stop treatment and enter the TFR phase. Patients with loss of major molecular response (MMR; BCR-ABL1IS⩽0.1%) during the TFR phase reinitiated nilotinib. In total, 215 patients entered the consolidation phase, of whom 190 entered the TFR phase. The median duration of nilotinib before stopping treatment was 43.5 months. At 48 weeks after stopping nilotinib, 98 patients (51.6%; 95% confidence interval, 44.2-58.9%) remained in MMR or better (primary end point). Of the 86 patients who restarted nilotinib in the treatment reinitiation phase after loss of MMR, 98.8% and 88.4%, respectively, regained MMR and MR4.5 by the data cutoff date. Consistent with prior reports of imatinib-treated patients, musculoskeletal pain-related events were reported in 24.7% of patients in the TFR phase (consolidation phase, 16.3%).

Treatment and outcome of 2904 CML patients from the EUTOS population-based registry.

The European Treatment and Outcome Study (EUTOS) population-based registry includes data of all adult patients newly diagnosed with Philadelphia chromosome-positive and/or BCR-ABL1+ chronic myeloid leukemia (CML) in 20 predefined countries and regions of Europe. Registration time ranged from 12 to 60 months between January 2008 and December 2013. Median age was 55 years and median observation time was 29 months. Eighty percent of patients were treated first line with imatinib, and 17% with a second-generation tyrosine kinase inhibitor, mostly according to European LeukemiaNet recommendations. After 12 months, complete cytogenetic remission (CCyR) and major molecular response (MMR) were achieved in 57% and 41% of patients, respectively. Patients with high EUTOS risk scores achieved CCyR and MMR significantly later than patients with low EUTOS risk. Probabilities of overall survival (OS) and progression-free survival for all patients at 12, 24 and 30 months was 97%, 94% and 92%, and 95%, 92% and 90%, respectively. The new EUTOS long-term survival score was validated: the OS of patients differed significantly between the three risk groups. The probability of dying in remission was 1% after 24 months. The current management of patients with tyrosine kinase inhibitors resulted in responses and outcomes in the range reported from clinical trials. These data from a large population-based, patient sample provide a solid benchmark for the evaluation of new treatment policies.

Antineoplastic activity of selected constituents of Duguetia glabriuscula.

The cytotoxic effects of seven constituents isolated from Duguetia glabriuscula were evaluated against Hep2 human larynx carcinoma cells. The cytotoxicity exhibited by beta-sitosterol was as strong as that of cis-platin. (+)-Alloaromadendran-10,14beta-diol caused inhibition of cellular growth with IC50 values lower than 25 microg/ml, a feature that was considered as revealing significant activity. Polycarpol showed borderline cytotoxicity, whereas the other compounds were inactive.
