Real world experience with the TREO device in standard EVAR: Mid-term results of 150 cases from a German Multicenter study.

Background: The objective of the study was to analyze mid-term results of unselected patients treated with the TREO (Terumo Aortic, Florida, USA) device at six German hospital sites. Methods: A multicenter, retrospective analysis of patients treated within and outside instructions for use (IFU) from January 2017 to November 2020 was performed. Primary outcomes were technical success, mortality and endograft related complications according to IFU status. Secondary outcomes were aneurysm/procedure related re-interventions. Results: 150 patients (92% male, mean age 73 ±8 years) were treated (within IFU 84% vs. outside IFU 16%) with the TREO device for abdominal aortic aneurysms (n=127 intact, n=17 symptomatic and n=6 ruptured; p=0.30). Technical success was achieved in 147/150 (within IFU 99% vs. outside IFU 92%, p=0.08). 30-day mortality was 2%, one year and overall mortality was 3% and 5%. During a mean follow-up of 28.4 months (range: 1-67.4 months), 35 (25%; within IFU 23% vs. outside IFU 35%, p=0.23) patients suffered from endoleaks. The majority were endoleaks type II (n=33), the remaining type Ia (n=5) and type Ib (n=3). No endoleaks type III-V, migrations or aneurysm ruptures occurred. Overall, 19 patients (13%; within IFU 13% vs. 15% outside IFU, p=0.70) received a secondary intervention: nine endoleak related endovascular procedures, three open conversions, two endograft limb related interventions, four surgical revisions of the femoral access sites and two bowl ischemia related procedures, respectively. Conclusions: This non industry-sponsored, multicenter trial indicates that using the TREO device in a real-world setting (both within and outside IFU) seems feasible in the treatment of patients suffering from AAA. While the rate of complications and secondary interventions is in line with previously published data, the findings highlight the fact that standard EVAR is associated with serious adverse events.

The prognostic relevance of pleural effusion in patients with COVID-19 - A German multicenter study

PurposeThis study evaluates the prognostic significance of pleural effusion (PE) in COVID-19 patients across thirteen centers in Germany, aiming to clarify its role in predicting clinical outcomes. MethodsIn this retrospective analysis within the RACOON project (Radiological Cooperative Network of the COVID-19 pandemic), 1183 patients (29.3 % women, 70.7 % men) underwent chest CT to assess PE. We investigated PE's association with 30-day mortality, ICU admission, and the need for mechanical ventilation. ResultsPE was detected in 31.5 % of patients, showing a significant correlation with 30-day mortality (47.5 % in non-survivors vs. 27.3 % in survivors, p < 0.001), with a hazard ratio of 2.22 (95 % CI 1.65–2.99, p < 0.001). No significant association was found between PE volume or density and mortality. ICU admissions were noted in 46.8 % of patients, while mechanical ventilation was required for 26.7 %. ConclusionPleural effusion is present in a significant portion of COVID-19 patients and independently predicts increased 30-day mortality, underscoring its value as a prognostic marker. Its identification, irrespective of volume or density, should be a priority in radiological reports to guide clinical decision-making.

Comparative effectiveness of vancomycin and metronidazole on event-free survival after initial infection in patients with Clostridioides difficile—a German multicentre cohort study

ObjectivesThe objective of this study is to examine the comparative effectiveness of vancomycin and metronidazole in a confirmatory analysis of event-free survival (EFS) after initial infection in patients with Clostridioides difficile from a German multicentre cohort study. MethodsThe IBIS multicentre cohort enrolled patients with an index episode of C. difficile infection between August 2017 and September 2020. The primary endpoint was EFS, defined as response to treatment with metronidazole or vancomycin within 10 days of initiation, absence of recurrence and death from any cause up to 90 days post-treatment. A Cox proportional hazards model with inverse probability of treatment weighting was used to investigate the comparative effectiveness of this outcome. Additionally, subgroup analyses were performed based on severe and non-severe infections. ResultsOf the 489 patients included, 118 (24%) received initial treatment with metronidazole and 371 (76%) with vancomycin. Of these, 78/118 (66.1%) and 247/371 (66.6%), respectively, responded to treatment within 10 days, neither developed a recurrence nor died within 90 days and thus achieved the outcome of EFS. In the subgroup of non-severe infections, 74/293 patients (25.3%) received metronidazole, and 219/293 (74.7%) received vancomycin. Of these, 33/74 (44.6%) metronidazole patients and 150/219 (68.5%) vancomycin patients survived event free. The Cox proportional hazards model revealed differences in EFS for the overall population and both subgroups (reference metronidazole: all severity levels: hazard ratio [HR] 0.46, [95% CI, 0.33–0.65]; non-severe: HR 0.39; [95% CI, 0.24–0.60]; severe: HR 0.52; [95% CI, 0.28–0.95]). DiscussionOur analysis confirms current changes in guidelines, as it supports the superiority of vancomycin compared with metronidazole across all severity levels.

Patients’ and caregivers’ perception of multidimensional and palliative care in amyotrophic lateral sclerosis – protocol of a German multicentre study

IntroductionAmyotrophic lateral sclerosis (ALS) is an inevitably fatal condition that leads to a progressive loss of physical functioning, which results in a high psychosocial burden and organizational challenges related to medical care. Multidimensional and multiprofessional care is advised to meet the complex needs of patients and their families. Many healthcare systems, including Germany, may not be able to meet these needs because non-medical services such as psychological support or social counselling are not regularly included in the care of patients with ALS (pwALS). Specialised neuropalliative care is not routinely implemented nor widely available. Caregivers of pwALS are also highly burdened, but there is still a lack of support services for them.MethodsThis project aims to assess the perceptions and satisfaction with ALS care in Germany in pwALS and their caregivers. This will be achieved by means of a cross-sectional, multicentre survey. The examination will assess, to which extend the patients’ needs in the six domains of physical, psychological, social, spiritual, practical and informational are being met by current care structures. This assessment will be linked to mental well-being, subjective quality of life, attitudes toward life-sustaining measures and physician-assisted suicide, and caregiver burden. The study aims to recruit 500 participants from nationwide ALS centres in order to draw comprehensive conclusions for Germany. A total of 29 centres, mostly acquired via the clinical and scientific German Network for Motor Neuron Diseases (MND-NET), will take part in the project, 25 of which have already started recruitment.PerspectiveIt is intended to provide data-based starting points on how current practice of care in Germany is perceived pwALS and their caregivers and how it can be improved according to their needs. Planning and initiation of the study has been completed.Trial registrationThe study is registered at ClinicalTrails.gov; NCT06418646

Safety and Efficacy of Extended Therapy with [177Lu]Lu-PSMA: A German Multicenter Study.

Prospective results have demonstrated favorable safety and efficacy of [177Lu]Lu-PSMA radiopharmaceutical therapy for up to 6 cycles in men with metastatic castration-resistant prostate cancer. However, no systematic data are available outlining the feasibility of extended therapy beyond 6 cycles. We aim to evaluate the safety and efficacy of extended [177Lu]Lu-PSMA radiopharmaceutical therapy in patients who have received more than 6 cycles. Methods: In total, 111 patients were included in this multicenter retrospective analysis. Based on individual decisions, patients underwent uninterrupted continuation of therapy (continuous treatment) or reexposure after a therapy break (rechallenge treatment) between 2014 and 2023. Overall survival, 50% prostate-specific antigen (PSA) decline (measured 8-12 wk after treatment initiation or rechallenge), PSMA PET response, and grades per Common Terminology Criteria for Adverse Events were assessed. χ2 tests, multivariable Cox regression analysis, and log-rank tests were applied for statistical analyses. Results: Patients received extended treatment with [177Lu]Lu-PSMA, either as a continuous treatment (43/111, 38.7%) or as a rechallenge (68/111, 61.3%) treatment, with median cumulative doses of 57.4 or 60.8 GBq, respectively. Overall survival from the initiation of [177Lu]Lu-PSMA was 31.3, 23.2, and 40.2 mo for the entire cohort, the continuous treatment group, and the rechallenge treatment group, respectively. The initial 50% PSA decline was significantly higher in the retreated group than in the continuous group (57/63 [90.4%] vs. 26/42 [61.9%]; P = 0.006). A 50% PSA decline was observed in 23 of 62 patients (37.1%) after the first rechallenge. The rate of grades 3-4 toxicity was comparable between continuous and rechallenge treatments (anemia, 7/43 [16.3%] vs. 13/68 [19.1%)], P = 0.6; leukocytopenia, 1/43 [2.3%] vs. 2/67 [3.0%], P = 0.3; thrombocytopenia, 3/43 [7.0%] vs. 3/68 [4.4%], P = 0.3; renal, 2/43 [4.7%] vs. 5/68 [7.4%], P = 0.2). Conclusion: Extended therapy with [177Lu]Lu-PSMA is safe and has not been associated with increased grades 3-4 toxicity. Patient candidates for extended treatment experienced a favorable median survival of 31.3 mo from the first administration. Response under [177Lu]Lu-PSMA rechallenge demonstrated preserved efficacy of [177Lu]Lu-PSMA after a treatment break.

Assessment of a novel BLOOMY score for predicting mortality in hospitalised adults with bloodstream infection

PurposeA German multicentre study BLOOMY was the first to use machine learning approach to develop mortality prediction scores for bloodstream infection (BSI) patients, but the scores have not been assessed in other cohorts. Our aim was to assess how the BLOOMY 14-day and 6-month scores estimate mortality in our cohort of 497 cases with BSI.MethodsClinical data, laboratory data, and patient outcome were gathered retrospectively from patient records. The scores were calculated as presented in the BLOOMY study with the exception in the day of the evaluation.ResultsIn our cohort, BLOOMY 14-day score estimated death by day 14 with an area under curve (AUC) of 0.87 (95% Confidence Interval 0.80–0.94). Using ≥ 6 points as a cutoff, sensitivity was 68.8%, specificity 88.1%, positive predictive value (PPV) 39.3%, and negative predictive value (NPV) 96.2%. These results were similar in the original BLOOMY cohort and outweighed both quick Sepsis-Related Organ Failure Assessment (AUC 0.76) and Pitt Bacteraemia Score (AUC 0.79) in our cohort. BLOOMY 6-month score to estimate 6-month mortality had an AUC of 0.79 (0.73–0.85). Using ≥ 6 points as a cutoff, sensitivity was 98.3%, specificity 10.7%, PPV 25.7%, and NPV 95.2%. AUCs of 6-month score to estimate 1-year and 5-year mortality were 0.80 (0.74–0.85) and 0.77 (0.73–0.82), respectively.ConclusionThe BLOOMY 14-day and 6-month scores performed well in the estimations of mortality in our cohort and exceeded some established scores, but their adoption in clinical work remains to be seen.

Effectiveness, safety and impact of guselkumab on sexuality and perceived stigmatization in patients with psoriasis in routine clinical practice: Week 28 results from the prospective German multicentre G-EPOSS study.

G-EPOSS is a prospective, non-interventional, German multicentre study of patients with moderate-to-severe plaque psoriasis receiving guselkumab, a therapeutic monoclonal antibody targeting interleukin-23, in a real-world setting. The objective of the study was to evaluate the effectiveness and safety of guselkumab, including its impact on skin, health-related quality of life (HRQoL), sexuality, and perceived stigmatization. Patients (≥18 years old) received guselkumab per routine clinical practice. The primary endpoint was the proportion of patients achieving absolute Psoriasis Area and Severity Index (PASI) ≤ 3 at Week (W)28. Secondary endpoint assessments over 28 weeks included the Nail Psoriasis Severity Index (NAPSI), anogenital Physician's Global Assessment (aPGA), and Dermatology Life Quality Index (DLQI). Sexuality and perceived stigmatization were assessed by patients using the Relationship and Sexuality Scale (RSS) and Perceived Stigmatization Questionnaire (PSQ), respectively. Overall, 293 patients were included in the evaluable set population. Mean age and disease duration were 45.6 and 17.6 years, respectively. At baseline, mean PASI, aPGA and DLQI scores were 15.3, 2.7 and 11.3, respectively. In total, 25.9% of patients had received a prior biologic. Overall, 83.0% of patients achieved PASI ≤ 3, and 56.2%/35.1% achieved PASI ≤ 1/PASI = 0, respectively, at W28. Among those with NAPSI ≥ 1 and aPGA ≥ 1 at baseline, NAPSI = 0 and aPGA = 0 were achieved by 39.2% and 61.1% of patients, respectively, and 61.4% of patients achieved DLQI 0-1 at W28. Improvements were observed over 28 weeks across individual items of the DLQI, RSS and PSQ, indicating improved HRQoL and sex life, and decreased perceived stigmatization. Based on DLQI Question (Q)9, 53.6% of patients experienced sexual difficulties at baseline, which decreased to 12.1% at W28. DLQI Q9 responses were consistent with RSS item responses, highlighting DLQI Q9 as a sentinel for sexual impairment. Guselkumab improved overall skin symptoms and HRQoL in patients with psoriasis and decreased sexual impairment and perceived stigmatization. No new safety signals were observed. CNTO1959PSO4008.

Outcomes with ibrutinib in patients with chronic lymphocytic leukaemia: Results from the German multicentre REALITY study.

To assess treatment adherence, effectiveness and safety outcomes of patients with chronic lymphocytic leukaemia (CLL) receiving ibrutinib in a real-world setting. Patients enrolled in REALITY were ≥18 years with a confirmed diagnosis of CLL and were receiving ibrutinib as a first-line (1L), 2L or ≥3L therapy. Treatment retention, adherence, progression-free survival (PFS), overall survival (OS) and time to next therapy were assessed at 1 and 2 years overall, by typology and by cytogenetic subgroups. PFS and OS were analysed using Kaplan-Meier methods. Exactly 302 patients were enrolled across 57 sites in Germany, from January 2017 to July 2021. One-year retention rates were 69.9% overall (primary endpoint), 77.9% for 1L patients, and 77.6%/78.8% for high-risk patients with del17p/TP53. At 2 years, PFS/OS rates were 77.8%/90.7% overall (1L, 82.7%/90.4%), and were consistent across cytogenetic subgroups. PFS rates were higher for 1L versus ≥3L patients. Patients with the low-acceptance/low-control typology at baseline were less likely to retain treatment at 1 year versus the high-acceptance/high-control typology. No new safety signals were observed. The REALITY study provides further evidence of the effectiveness and safety of ibrutinib in patients with CLL in a real-world setting, particularly in earlier treatment lines.

Correct and Incorrect Recommendations for or against Fine Needle Biopsies of Hypofunctioning Thyroid Nodules: Performance of Different Ultrasound-based Risk Stratification Systems.

To evaluate the recommendations for or against fine needle biopsy (FNB) of hypofunctioning thyroid nodules (TNs) using of five different Ultrasound (US) -based risk stratification systems (RSSs). German multicenter study with 563 TNs (≥ 10 mm) in 534 patients who underwent thyroid US and surgery. All TNs were evaluated with ACR TI-RADS, EU-TIRADS, ATA, K-TIRADS 2016 and modified K-TIRADS 2021. A correct recommendation was defined as: malignant TN with recommendation for FNB (appropriate) or benign TN without recommendation for FNB (avoided). An incorrect recommendation was defined as: malignant TN without recommendation for FNB (missed) or benign TN with recommendation for FNB (unnecessary). ACR TI-RADS demonstrated the highest rate of correct (42.3 %) and lowest rate of incorrect recommendations (57.7 %). The other RRSs showed similar results for correct (26.5 %-35.7 %) and incorrect (64.3 %-73.5 %) recommendations. ACR TI-RADS demonstrated the lowest rate of unnecessary (73.4 %) and the highest rate of appropriate (26.6 %) FNB recommendation. For other RSSs, the rates of unnecessary and appropriate FNB were between 75.2 %-77.1 % and 22.9 %-24.8 %. The lowest rate of missed FNB (14.7 %) and the highest rate of avoided FNB (85.3 %) was found for ACR TI-RADS. For the other RSSs, the rates of missed and avoided FNB were between 17.8 %-26.9 % and 73.1 %-82.2 %. When the size cutoff was disregarded, an increase of correct recommendations and a decrease of incorrect recommendations was observed for all RSSs. The RSSs vary in their ability to correctly recommend for or against FNB. An understanding of the impact of nodule size cutoffs seems necessary for the future of TIRADS.

Paediatric spine injuries in the thoracic and lumbar spine—results of the German multicentre CHILDSPINE study

BackgroundPaediatric thoracolumbar spine injuries are rare, and meaningful epidemiological data are lacking.ObjectivesThe aim of this study was to provide epidemiological data for paediatric patients with thoracolumbar spinal trauma in Germany with a view to enhancing future decision-making in relation to the diagnostics and treatment of these patients.Materials and MethodsA retrospective multicentre study includes patients up to 16 years of age who were suffering from thoracolumbar spine injuries who had been treated in six German spine centres between 01/2010 and 12/2016. The clinical database was analysed for patient-specific data, trauma mechanisms, level of injury, and any accompanying injuries. Diagnostic imaging and subsequent treatment were investigated. Patients were divided into three age groups for further evaluation: age group I (0–6 years), age group II (7–9 years) and age group III (10–16 years).ResultsA total of 153 children with 345 thoracolumbar spine injuries met the inclusion criteria. The mean age at the time of hospitalization due to the injury was 12.9 (± 3.1) years. Boys were likelier to be affected (1:1.3). In all age groups, falls and traffic accidents were the most common causes of thoracolumbar spine injuries. A total of 95 patients (62.1%) were treated conservatively, while 58 (37.9%) of the children underwent surgical treatment. Minimally invasive procedures were the most chosen procedures. Older children and adolescents were likelier to suffer from higher-grade injuries according to the AOSpine classification. The thoracolumbar junction (T11 to L2) was the most affected level along the thoracolumbar spine (n = 90). Neurological deficits were rarely seen in all age groups. Besides extremity injuries (n = 52, 30.2%), head injuries represented the most common accompanying injuries (n = 53, 30.8%). Regarding spinal injuries, most of the patients showed no evidence of complications during their hospital stay (96.7%).ConclusionsThe thoracolumbar junction was more frequently affected in older children and adolescents. The majority of thoracolumbar spinal column injuries were treated conservatively. Nevertheless, 37.9% of hospitalized children had to be treated surgically, and there was an acceptable complication rate for the surgeries that were performed.

Effectiveness, safety and quality-of-life effects of guselkumab and ustekinumab in patients with psoriasis: Week 104 results from the non-interventional, prospective, German multicentre PERSIST study.

PERSIST was a prospective, non-interventional, real-world study of guselkumab and ustekinumab in adult patients with moderate-to-severe plaque psoriasis in Germany. To examine effectiveness, safety and quality-of-life (QoL) outcomes to Week (W) 104 of treatment with guselkumab and ustekinumab in patients with moderate-to-severe plaque psoriasis. Patients (≥18 years of age) received guselkumab or ustekinumab as per routine clinical practice. Outcomes to W104 were examined separately in guselkumab and ustekinumab recipients. An ad hoc exploratory analysis of outcomes with guselkumab versus ustekinumab was also performed following propensity score matching. Overall, 302 and 313 patients received guselkumab and ustekinumab, respectively. Patients in both cohorts experienced improvements in disease activity and QoL that were maintained to W104, with 64.7% and 63.6% of guselkumab- and 54.6% and 64.4% of ustekinumab-treated patients achieving a Psoriasis Area and Severity Index (PASI) 90 response and a Dermatology Life Quality Index (DLQI) 0/1 score, respectively. Propensity score matching yielded well-balanced baseline characteristics except for prior biologic use, which was higher in guselkumab versus ustekinumab recipients (51.7% vs. 32.0%). Achievement of PASI ≤1 at W104 was more common in guselkumab versus ustekinumab recipients (58.7% vs. 49.7%). The W104 PASI90 response rate was 65.6% with guselkumab and 56.0% with ustekinumab; corresponding rates for PASI100 were 44.3% and 28.5%. In guselkumab recipients, response rates were higher in biologic-naïve versus biologic-experienced patients (PASI90, 77.1% vs. 53.4%; PASI100, 55.0% vs. 33.0%). A high level of response for QoL outcomes was observed for both treatments. Ustekinumab and guselkumab led to improvements in physician-assessed and patient-reported outcomes that were sustained for up to 2 years, with no new safety signals identified. Following propensity score matching, greater improvements in PASI outcomes were observed with guselkumab versus ustekinumab. Improvements with guselkumab were highest in biologic-naïve patients, highlighting the value of early treatment.

BTA stat®, NMP22® BladderChek®, UBC® Rapid Test, and CancerCheck® UBC® rapid VISUAL as urinary marker for bladder cancer: Final results of a German multicenter study

Introduction and objectiveBTA stat®, NMP22® BladderChek®, UBC® Rapid Test, and CancerCheck® UBC® rapid VISUAL are urinary-based rapid tests. This multicenter study is the first study comparing all available rapid tests on a large cohort of bladder cancer patients and healthy controls in one setting. MethodsIn total 732 urine samples (second morning urine) in a real-world assessment have been analyzed. We evaluated clinical samples from 464 patients with histologically confirmed urothelial tumors of the urinary bladder (17 solitary CIS, 189 low-grade, 187 high-grade nonmuscle invasive, 71 high-grade muscle invasive), 77 patients with No Evidence of Disease (NED), and from 191 healthy controls. Urine samples were analyzed by the BTA stat®, NMP22® BladderChek®, UBC® Rapid Test point-of-care (POC) system using the concile Omega 100 POC reader, and CancerCheck® UBC® rapid VISUAL. Sensitivities and specificities were calculated by contingency analyses. ResultsAll investigated urinary markers detected more pathological concentrations in urine of bladder cancer patients compared to tumor-free patients. The calculated diagnostic sensitivities for BTA stat®, NMP22® BladderChek®, UBC® Rapid Test, CancerCheck® UBC® rapid VISUAL, and cytology were 62.4%, 13.4%, 58.2%, 28.6%, 36.2% for low-grade, 83.4%, 49.5%, 84.5%, 63.1%, 71.2% for high-grade nonmuscle invasive, and 95.8%, 35.2%, 76.1%, 50.7%, 67.7% for high-grade muscle-invasive bladder cancer. The specificity was 67.9%, 95.5%, 79.4%, 94.4%, and 83.7%, respectively. The area under the curve (AUC) after receiver operating characteristics (ROC) analysis for high-grade non–muscle-invasive tumors was 0.757, 0.725, 0.819, 0.787, and 0.774, respectively. ConclusionsThe analysis of more than 700 urine samples offers an objective view on urine-based rapid diagnostics. Elevated pathological concentrations of markers in urine of bladder cancer patients were detected in all investigated tests. The highest sensitivities for high-grade non–muscle-invasive tumors were calculated for BTA stat® and UBC® Rapid Test, whereas NMP22® BladderChek®, and cytology showed the highest specificities. BTA stat® and UBC® Rapid Test have the potential to be used as a clinical valuable urinary protein biomarker for the detection of high-grade non–muscle-invasive bladder cancer patients and could be included in the management of these tumors.

Development Trajectories of Fatigue, Quality of Life, and the Ability to Work among Colorectal Cancer Patients in the First Year after Rehabilitation-First Results of the MIRANDA Study.

Cancer-related fatigue, low quality of life (QoL), and low ability to work are highly prevalent among colorectal cancer (CRC) patients after tumor surgery. We aimed to analyze their intercorrelations and trajectories in the first year after in-patient rehabilitation in the German multicenter MIRANDA cohort study. Recruitment is ongoing, and we included the first 147 CRC patients in this analysis. Participants filled out questionnaires at the beginning of in-patient rehabilitation (baseline) and at 3, 6, 9, and 12 months after the baseline. The EORTC-QLQ-C30-General-Health-Status (GHS)/QoL, the FACIT-F-Fatigue Scale, and the FACIT-F-FWB-ability-to-work items were used to evaluate QoL, fatigue, and ability to work, respectively. The fatigue and QoL scales were highly correlated (r = 0.606). A moderate correlation was observed between the fatigue and ability to work scales (r = 0.487) and between the QoL and ability to work scales (r = 0.455). Compared to the baseline, a statistically significant improvement in the QoL, ability to work, and fatigue scales were observed at the 3-month follow-up (Wilcoxson signed rank test, all p < 0.0001). The three scales plateaued afterward until the 12-month follow-up. In conclusion, fatigue, QoL, and ability to work were highly interrelated, improved quickly during/after in-patient rehabilitation, and did not change much afterward in German CRC patients.

Pediatric cervical spine injuries—results of the German multicenter CHILDSPINE study

ObjectivesThe aim of this study was to provide epidemiological data of pediatric patients suffering from cervical spinal trauma in Germany, in order to integrate these data in future decision-making processes concerning diagnosis and therapy.Materials and MethodsRetrospective multicenter study includes all patients up to 16 years suffering from cervical spine injuries who were treated in six German spine centers between 01/2010 and 12/2016. The clinical databases were screened for specific trauma mechanism, level of injury as well as accompanying injuries. Diagnostic imaging and the chosen therapy were analyzed. Patients were divided into three age groups for further evaluation: age group I (0–6 years), age group II (7–9 years), age group III (10–16 years).ResultsA total of 214 children with 265 cervical spine injuries were included during the mentioned period. The mean age at the time of injury was 11.9 (± 3.9) years. In age group I, 24 (11.2%) patients were included, age group II consisted of 22 patients (10.3%), and 168 patients belonged to age group III (78.5%). Girls and boys were equally affected. In all age groups, falls and traffic accidents were the most common causes of cervical spine injuries. A total of 180 patients (84.1%) were treated conservatively, while 34 (15.9%) children underwent surgery. Distorsion/whiplash injury was the most common entity (n = 165; 68.2%). Children aged 0–9 years had significantly (p < 0.001) more frequent injuries of the upper cervical spine (C0-C2) compared to older age groups. Patients of age group III were more likely to suffer from injuries in subaxial localizations. Neurological deficits were rarely seen in all age groups. Head injuries did represent the most common accompanying injuries (39.8%, n = 92).ConclusionsThe upper cervical spine was more frequently affected in young children. Older children more often suffered from subaxial pathologies. The majority of cervical spinal column injuries were treated conservatively. Nevertheless, 15% of the hospitalized children had to be treated surgically.

Patients' perspectives on a patient-oriented electronic decision support tool to reduce overuse of proton pump inhibitors (arriba-PPI): a qualitative study in primary care

BackgroundTo evaluate patients’ perspectives and their experiences with a consultation involving a computer-assisted and patient-centered discontinuation strategy (arriba-PPI tool) as part of a German multicenter study on reducing the prescription of proton pump inhibitors (PPIs).MethodsQualitative in-depth telephone interviews on proton pump inhibitors with patients who had received an arriba-PPI tool-based counseling by their general practitioner (GP). A random sample of 30 patients was taken from study participants. Interviews were conducted in 2020 and analyzed using a thematic qualitative text analysis.ResultsAlthough this was meant to be the key to shared decision making with regard to PPI reduction, study participants mostly did not recall the visual features of the tool. However, a few patients remembered them very clearly. Above all, patients appreciated a trustful relationship with the GP as well as comprehensive, individualized counseling.ConclusionApplication of the arriba-PPI tool can support the decision process but can also hinder the consultation process if the tool is not properly embedded in the consultation. GPs using the arriba-PPI tool to support the shared decision-making process should consider the patients’ and their own expectations on the benefit of the visual representation of the tool.

Predictors of Decreased Quality of Life in Breast Cancer Survivors Five Years After Diagnosis.

Due to improved therapy, early diagnosis, and growing incidence rates, the number of long-term breast cancer survivors is increasing. Survivors can still be affected by aftercare, resulting in reduced quality of life (QoL). Thus, in this study, we investigated possible predictors of decreased physical and social functioning in breast cancer survivors. In a German multicenter prospective study, we enrolled 759 female patients with breast cancer before surgery (t1), and contacted them again 5 years after surgery (t4). Data on QoL were assessed at t4 using the European Organization for Research and Treatment of Cancer QoL Core Questionnaire (EORTC QLQ-C30) and its breast cancer module EORTC QLQ-BR23. Predictors of decreased physical and social functioning were analyzed using logistic regression with odds ratios as effect estimates and 95% confidence intervals. Thresholds for the clinical importance of detrimental effects on QoL were defined according to Giesinger. Questionnaires from 759 patients were retrieved at t1. Of these, 456 participated in the study at t4. Poor QoL 5 years after diagnosis was reported by 20%-50% of the participants. Age, mastectomy, chemotherapy, education, employment, cohabitation, psychiatric comorbidities at t1, anxiety, depression, and intensity of physical activity emerged as predictors of decreased physical and social functioning 5 years after diagnosis. Relief of symptoms and improvement in the QoL should be priorities in aftercare. Detecting patients with a decreased QoL is a rising challenge. Healthcare providers should take special care of patients aged 50-59 years, patients with psychiatric comorbidities and depression, and patients who have undergone mastectomy.

Inotuzumab Ozogamicin Induction Followed By Standard Chemotherapy Yields High Remission Rates and Promising Survival in Older (>55 Years) Patients with De Novo B-Lymphoblastic Leukemia (GMALL-Initial1 Trial)

Introduction: Acute lymphoblastic leukemia (ALL) represents approx. 5% of all newly diagnosed leukemias in patients (pts) between 55 and 70 years of age. Incorporation of novel antibody-based therapies in the first line induction therapy bears the potential of a significantly increased response rates and survival together with a reduction of treatment toxicity. Methods: This open label phase II study (ClinicalTrials.gov, identifier: NCT03460522) of the German Multicenter Study Group on Adult Acute Lymphoblastic Leukemia was conducted at 13 centers. Pts aged >55 years with newly diagnosed Ph/BCR-ABL negative B-precursor ALL (at least CD20 positivity of leukemic blasts) were eligible. The 1st induction cycle consisted of InO 0.8mg/m2 on day1 and 0.5mg/m2 on d8 and d15 together with dexamethasone 10 mg/m2 (day7-8, day14-17) and one intrathecal injection (i.th.) of methotrexate (MTX), cytarabine (AraC) and dexamethasone (Dex). The 2nd and 3rd induction cycle consisted of InO 0.5mg/m2 on day 1, 8 and 15 plus i.th. MTX/AraC/Dex. Pts achieving a complete remission (CR) were offered to receive 5 conventional consolidation therapies (3 x ID-MTX/asparaginase; 2 x ID-AraC) and one reinduction therapy (idarubicine/ AraC/ cyclophosphamide / Dex.) in combination with rituximab (for CD20+ ALL), followed by a maintenance therapy with 6-MP/MTX. The primary endpoint was event free survival (EFS) at 12-months follow-up. An event was defined as any of the following: persisting bone marrow blasts after 2 cycles of InO, relapse or death. An event rate of ≤40% at 12 months follow-up was considered to qualify the experimental treatment as very promising for additional testing. Results: 43 out of the 45 pts included were analyzed regarding the primary end point. Two pts were excluded per protocol from further analysis, as they received only one cycle of induction or withdraw consent. At diagnosis, median age was 64 years (range 56-80 years, 20 pts ≥65 years and 12 pts ≥70 years), median bone marrow blast count was 80% and median CD22 expression on leukemic blasts was 69% (range 21-99). 38 pts were diagnosed with a common- and 5 with a pro-B ALL. 42/43 pts completed all 3 cycles of induction therapy. All 43 pts achieved a complete remission (CR/CRi), mainly after the 1st induction. Median time between start of 1st induction to start 2nd induction, from 2nd to 3rd induction and from 3rd induction to 1st consolidation therapy was 21 days, 28 days and 30 days, respectively. Results of minimal residual disease (MRD), measured by real-time quantitative PCR, are available for all 43 pts, with 23/43 (53%) and 31/42 (74%) pts being MRD negative after 2nd and 3rd induction therapy, respectively. With a median follow-up of 697 days, the probability of OS at 1 and 2 years is 91% (95% C.I. 82-99%) and 81% (95% C.I. 69-94%), respectively. No patient died within the first 6 months after start of induction therapy. 5 events occurred within the first year after study inclusion, 3 deaths in CR and 2 relapsed ALL, resulting in event rate of 12% and a probability of EFS at 1 year (primary endpoint of the study) of 88% (95% CI 79-98). EFS at 2 years was 73% (95% CI 59-88). So far, 7 pts with persisting/reappearance of MRD (2 pts) or relapse (5 pts) were treated with blinatumomab. 9 pts received an aSCT (4 pts in CR1 and 5 pts >CR1), 6 of these pts are alive in CR. Regarding adverse events (AEs) during induction cycles 1, 2 and 3, most common AEs ≥CTC grade 3 reported were leukocytopenia (in 74%, 19% and 2% of all cases, respectively), anemia (37%, 5%, 0%), thrombocytopenia (49%, 7%, 2%) and elevation of liver enzymes (14%, 5%, 0%). One patient was reported with suspected veno occlusive disease (after 2nd induction therapy). Classical factors which may be associated with inferior survival outcomes like age, diagnosis of pro-B ALL, disease burden at diagnosis, co-morbidity or no MRD negative CR after induction had no significant impact on OS or EFS. Conclusion: Three cycles of InO as induction therapy for the treatment of older pts with de novo acute B-lymphoblastic leukemia resulted in a very high remission rate. Given that our study met the primary end point (predefined event rate at 1 year ≤40%, observed event rate 12%), these promising study results could be a rationale for integrating InO induction therapy in future treatment recommendations. Ideally, this novel induction therapy should be evaluated in prospective randomized trials. Figure 1View largeDownload PPTFigure 1View largeDownload PPT Close modal

Distress in soft-tissue sarcoma and gastrointestinal stromal tumours patients-Results of a German multicentre observational study (PROSa).

Soft tissue sarcomas (STS) and gastrointestinal stromal tumours (GIST) are a group of rare malignant tumours with a high and heterogenous disease burden. As evidence is scarce, we analysed the prevalence of increased emotional distress and identified distress-associated factors in these patients. The PROSa-study (Burden and medical care of sarcoma) was conducted between 2017 and 2020 in 39 study centres. Cross-sectional data from adult STS and GIST patients were analysed. Distress was measured with the Patient Health Questionnaire (PHQ-4). The relation of socioeconomic and clinical factors with distress was explored in adjusted logistic regression models. Among 897 patients, 17% reported elevated anxiety and 19% reported depression. Unemployed patients (odds ratio [OR] 6.6; 95% CI 2.9-15.0), and those with a disability pension (OR 3.1; 95% CI 1.9-5.0) were more likely to experience distress compared to employed patients. Also, patients with a disability pass had higher odds of increased distress than those without (OR 1.8; 95% CI 1.2-2.7). Lowest distress was observed in patients 2 to <5years and ≥5years after diagnosis (comparison: <6months) (OR 0.4; 95% CI 0.2-0.6) and (0.3; 95% CI 0.2-0.6). Patients with thoracic STS (vs. lower limbs) had twice the odds to experience distress (OR 2.0; 95% CI 1.1-3.6). Distress was seen almost twice as often in patients with progressive disease (vs. complete remission) (OR 1.7; 95% CI 1.1-2.8). The prevalence of elevated distress in STS and GIST patients is high. In unemployed patients, in those with a disability pension and in newly diagnosed patients a noticeable increase was observed. Clinicians should be aware of these factors and consider the social aspects of the disease.

Evaluation of FAM19A4/miR124-2 methylation performance in the management of CIN3 diagnosed pregnant women.

Pregnant women diagnosed with CIN3 have high regression rates after delivery. Biomarkers are needed to only identify pregnant women with progressive CIN requiring treatment to reduce overreferral and overtreatment. In our study we evaluated the performance of the FAM19A4/miR124-2 methylation test for molecular triage on FFPE samples of CIN3+-diagnosed pregnant women with known clinical course over time as well in a cross-sectional setting. In this German multicenter retrospective study biopsy material was collected from pregnant women diagnosed with cervical cancer (n=16), with CIN3 that progressed to cancer during pregnancy (n=7), with CIN3 that regressed to CIN1 or less within 6months after delivery (n=41), without CIN (n=16), CIN3 covering 3-4 quadrants (n=14) and randomly selected CIN3 (n=41). FAM19A4/miR124-2 methylation analysis was performed blinded on first diagnosis. All pregnant women with cervical cancer and with CIN3 progressing to cancer tested positive for FAM19A4/miR124-2 methylation (100%, 22/22). In the regressing CIN3 group 47.5% and in the group without CIN 21.6% tested methylation positive. High-volume CIN3 and random selected CIN3 were methylation-positive in 91.7% and 82.1%, respectively. Methylation levels were significantly higher in progressive CIN3 and cancer compared to the controls (P < .0005). The likelihood ratio of a negative methylation test (LR-) for progressive CIN3+ was 0 (95% CI: 0-0.208). A negative FAM19A4/miR124-2 methylation test can rule out progressive CIN disease in pregnant women diagnosed with CIN3. This can help the clinician by managing these pregnant women with conservative follow-up until after delivery.
