[Multicenter trial for sudden hearing loss therapy - planning and concept]. / Multizentrische Studie zur Hörsturztherapie - Planung und Konzeption.

Systemic steroids are widely used worldwide as a standard of care for primary therapy of idiopathic sudden sensorineural hearing loss (ISSHL). The German ISSHL guideline recommends high-dose steroids for primary therapy of ISSHL, without evidence from randomized controlled trials (RCTs). The rationale for the treatment of ISSHL using high dose steroids is only based on retrospective cohort studies.This article describes the planning and initiation of a multicenter, national, randomized, controlled clinical trial entitled Efficacy and safety of high dose glucocorticosteroid treatment for idiopathic sudden sensorineural hearing loss - a three-armed, randomized, triple-blind, multicenter trial (HODOKORT). This clinical trial aims to compare standard dose with two types of high-dose steroids for primary systemic therapy with respect to their efficacy in improving hearing, and thus communication ability, in patients with idiopathic sudden sensorineural hearing loss.This study is funded by the "Clinical Trials with High Patient Relevance" research program in the health research framework of the German Federal Ministry of Education and Research. It is one of two studies by the German Study Center of Clinical Trials of the German Society of Otorhinolaryngology, Head and Neck Surgery (DSZ-HNO). Planning and initiation was done in cooperation with the DSZ-HNO, the Coordination Center of Clinical Trials of the Martin-Luther-University Halle-Wittenberg, and the Study Center of the University Hospital Freiburg.

Influence of age on outcome after allogeneic hematopoietic cell transplantation: a single center study in patients aged ⩾60.

Reduced intensity conditioning regimens lead to an increasing use of allogeneic hematopoietic cell transplantation (HCT) in elderly patients. We retrospectively analyzed 151 patients aged ⩾60 receiving allogeneic HCT 2000-2012 at our center. Median age was 66 years. Kaplan-Meier estimated 3-year OS was 42% with a median follow-up of 38 months. Cumulative incidences of progression and non-relapse mortality after 3 years were 38 and 24%. OS was better in the group of patients >65 years with a Kaplan-Meier estimated OS of 50% vs 34%, P=0.060. We observed a significant influence of donor age (<50 years: 53% vs >50 years: 30%, P=0.017) and gender match (matched: 57% vs mismatched: 32%, P=0.007) on outcome. The use of a matched related donor was inferior compared with a matched or mismatched unrelated donor (19% vs 47%, P=0.015). On multivariate analysis there was an increased hazard ratio for a non-gender-matched HLA-matched-related donor (hazard ratio 3.23, 95% confidence interval 1.55-6.74, P=0.002). Age had no significant impact on OS (P=0.414). In conclusion, the data suggest that older age alone has no negative impact on the outcome of allogeneic HCT. Transplant decision should be tailored to disease risk and patient performance status rather than age.

Efficacy of bath psoralen plus ultraviolet A (PUVA) vs. system PUVA in psoriasis: a prospective, open, randomized, multicentre study.

BACKGROUND: Plaque psoriasis is an inflammatory disease affecting approximately 2% of the population. The clinical hallmarks of psoriasis are sharply demarcated, erythematous plaques with thick scales. Photochemotherapy (psoralen plus ultraviolet A, PUVA) is one of the most effective therapies of psoriasis. The photosensitizer 8-methoxypsoralen (8-MOP) can be applied either orally (system PUVA) or topically in a warm water bath (bath PUVA). OBJECTIVES: To compare bath PUVA and system PUVA in the treatment of plaque psoriasis. METHODS: This was a randomized, open, prospective, multicentre trial. We included 74 patients with moderate-to-severe plaque psoriasis during a 6-week treatment and a 4-week follow-up period. Of the patients enrolled in the study, 38 received bath PUVA and 36 system PUVA. RESULTS: Both treatment modalities significantly reduced the median Psoriasis Area and Severity Index (PASI) score in the intention-to-treat population. Within 6 weeks bath PUVA reduced the median PASI by 74% (16·4 to 4·2) while system PUVA did so by 62% (15·3 to 5·8). The difference between the two modalities was not significant with regard to treatment efficacy (P = 0·389). CONCLUSION: There is no difference between bath PUVA and system PUVA in the treatment of psoriasis.

Ten-year analysis of the prospective multicentre Chemo-N0 trial validates American Society of Clinical Oncology (ASCO)-recommended biomarkers uPA and PAI-1 for therapy decision making in node-negative breast cancer patients.

AIM: Final 10-year analysis of the prospective randomised Chemo-N0 trial is presented. Based on the Chemo-N0 interim results and an European Organisation for Research and Treatment of Cancer (EORTC) pooled analysis (n=8377), American Society of Clinical Oncology (ASCO) and Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) guidelines recommend invasion and metastasis markers urokinase-type plasminogen activator (uPA)/plasminogen activator inhibitor-1 (PAI-1) for risk assessment and treatment decision in node-negative (N0) breast cancer (BC). METHODS: The final Chemo-N0 trial analysis (recruitment 1993-1998; n=647; 12 centres) comprises 113 (5-167) months of median follow-up. Patients with low-uPA and PAI-1 tumour tissue levels (n=283) were observed. External quality assurance guaranteed uPA/PAI-1 enzyme-linked immunosorbent assay (ELISA) standardisation. Of 364 high uPA and/or PAI-1 patients, 242 agreed to randomisation for CMF chemotherapy (n=117) versus observation (n=125). RESULTS: Actuarial 10-year recurrence rate (without any adjuvant systemic therapy) for high-uPA/PAI-1 observation group patients (randomised and non-randomised) was 23.0%, in contrast to only 12.9% for low-uPA/PAI-1 patients (plog-rank=0.011). High-risk patients randomised to cyclophosphamide-methotrexate-5-fluorouracil (CMF) therapy had a 26.0% lower estimated probability of disease recurrence than those randomised for observation (intention-to-treat (ITT)-analysis: hazard ratio (HR) 0.74 (0.44-1.27); plog-rank=0.28). Per-protocol analysis demonstrated significant treatment benefit: HR 0.48 (0.26-0.88), p=0.019, disease-free survival (DFS) Cox regression, adjusted for tumour stage and grade. CONCLUSIONS: Chemo-N0 is the first prospective biomarker-based therapy trial in early BC defining patients reaching good long-term DFS without adjuvant systemic therapy. Using a standardised uPA/PAI-1 ELISA, almost half of N0-patients could be spared chemotherapy, while high-risk patients benefit from adjuvant chemotherapy. These 10-year results validate the long-term prognostic impact of uPA/PAI-1 and the benefit from adjuvant chemotherapy in the high-uPA/PAI-1 group at highest level of evidence. They thus support the guideline-based routine use of uPA/PAI-1 for risk-adapted individualised therapy decisions in N0 breast cancer.

[Symptom-oriented follow-up of early breast cancer compared to intensive surveillance. Results of a prospective multicentre study: update and 10-year overall survival]. / Symptomorientierte Nachsorge nach Mammakarzinom im Vergleich zur intensiv-apparativen Nachsorge. Ergebnisse einer prospektiven multizentrischen Studie: Update und 10-Jahres-Überlebenszeit.

BACKGROUND AND OBJECTIVE: In a prospective, non-randomised, multicentre cohort study we compared intensive surveillance to symptom-oriented control in the follow-up of patients with early breast cancer after curative surgical treatment. Five-year overall survival had shown that symptom-oriented follow-up was not inferior to intensive control. However, a more intensive, instrumental based follow-up is still claimed by many patients and their physicians. In this context the recent data of 10-year overall survival (OS) are reported. PATIENTS AND METHODS: In the prospective, non-randomised, multicentre cohort study carried out between 1995 and 2000, 244 patients underwent an intensive follow-up (scheduled laboratory tests including CEA and CA 15-3, chest X-rays and liver ultrasound). 426 patients were monitored in a symptom-oriented manner (additional tests only in the case of symptoms indicating possible recurrence). Mammography, structured histories and physical examinations were done regularly in both groups. RESULTS: In the clinical follow-up group, 90 deaths (21.2 %) were observed with an estimated 10-year overall survival rate of 83.0 % (95 % CI 79.1 -86.3 %).  In the intensive follow-up group, 59 deaths (24.2 %) were observed with an estimated 10-year overall survival rate of 78.5 % (95 % CI 72.6 -83.2 %). The Cox proportional hazards model for OS includes the variables follow-up form, stage of primary tumor and lymph nodes, hormone receptor status, grading and age at diagnosis. This model resulted in a hazard ratio of 1.10 (95 % CI 0.78-1.54) for the follow-up protocol (intensive vs. clinical). Welleks' test for non-inferiority showed that clinical follow-up is not inferior in comparison to intensive follow-up (p < 0.05) for a non-inferiority limit of + 7 % at 10-years. CONCLUSION: This analysis of 10-year overall survival of patients with early breast cancer after curative primary treatment confirms that follow-up without regular imaging and laboratory tests is not inferior in the sense of a relevant higher mortality. To what extent new concepts in the treatment of breast cancer have any influence on follow-up care has to be examined in further studies.

An international opinion research survey of the etiology, diagnosis, therapy and outcome of Kienböck's disease (KD).

OBJECTIVES: Every fourth publication on Kienböck's disease (KD) is based for the most part on rather divergent expert opinion. We therefore surveyed expert opinion on KD in three European countries: (1) for the suspected aetiologies; (2) routinely used diagnostic tools; (3) recommended treatment and (4) expected outcome. METHODS: A questionnaire consisting of 16 questions was handed out at the national meetings for surgery of the hand in Germany (DE), France (FR) in 2009 and in the United Kingdom (UK) in 2010. RESULTS: Among the 126 surgeons who participated in the survey, 82 had a national diploma for surgery of the hand. None of the most commonly discussed etiopathological hypotheses were estimated as being very likely. Hand/arm vibration exposure was considered less likely among respondents in France and the UK than among respondents in Germany. Treatment recommendations are very heterogeneous for stage IIIB according to Lichtman. CONCLUSIONS: Expert opinions on diagnostic criteria, the pathogenesis and the choice of treatment are not consistent and may vary from one country to another.

Effect of water management, arsenic and phosphorus levels on rice in a high-arsenic soil-water system: II. Arsenic uptake.

Rice consumption is one of the major pathways for As intake in populations that depend on a rice diet in several countries of South and South-east Asia. Pot experiments were undertaken to investigate the effects of water management (WM), arsenic (As) contaminated soil-water and Phosphorus (P) rates on As uptake in rice plants. There were 18 treatments comprising of three each of As rates (0, 20 and 40 mg kg(-1) soil) and P rates (0, 12.5 and 25 mg kg(-1) soil) and two WM (aerobic and anaerobic) strategies on winter (boro var. BRRI dhan 29) and monsoon (aman var. BRRI dhan 32) rice at the Wheat Research Center (WRC), Nashipur, Dinajpur, Bangladesh. Arsenic concentrations in rice grain and straw increased significantly (P ≤ 0.01) with the increasing As rates in the soil. Arsenic availability in soil pore-water solution was less (58%) under aerobic WM (redox potential-Eh=+135 to +138 mV; pH-6.50 at 24.3 °C) as compared to anaerobic WM (flooded: Eh=-41 to -76 mV; pH-6.43 at 23 °C). The highest total grain As content 2.23 ± 0.12 mg kg(-1) and 0.623 ± 0.006 mg kg(-1) was found in T(6) (P(12.5)As(40)-anaerobic) and T(9) (P(25)As(40)-anaerobic) in BRRI dhan 29 and BRRI dhan 32, respectively, which was significantly higher (41-45%) than in the same As and P treatments for pots under aerobic WM. The As content in rice straw (up to 24.7 ± 0.49 ppm in BRRI dhan 29, 17.3 ± 0.49 mg kg(-1) in BRRI dhan 32 with the highest As level) suggested that As can more easily be translocated to the shoots under anaerobic conditions than aerobic condition. BRRI dhan 29 was more sensitive to As than BRRI dhan 32. Under aerobic WM, P soil amendments reduced As uptake by rice plants. The study demonstrated that aerobic water management along with optimum P amendment and selection of arsenic inefficient rice varieties are appropriate options that can be applied to minimize As accumulation in rice which can reduce effects on human and cattle health risk as well as soil contamination.

[100 years after Kienböck's description: review of the etiology of Kienböck's disease from a historical perspective]. / 100 Jahre nach Kienböck: Literaturübersicht über die Ursachenforschung der Mondbeinnekrosen.

Kienböck's disease (KD) leads to collapse of the lunate bone with severe consequences for the wrist function which for some patients may result in occupational invalidity. The many synonyms of KD (aseptic necrosis or avascular necrosis) insinuate that the true etiopathology remains poorly understood. This reviews aims at exploring the level of evidence which brought forward the different hypotheses on the origin of KD. The widespread theories about the origin were formed about 100 years ago but a specific therapy is still not within reach. Although the cause of the disease remains essentially unknown it is officially recognized as an occupational disease in Germany. Empirical attempts to explain the etiopathology are based on compression of the lunate, impaired vascularity through vibration exposition, fracture and dislocation of the lunate from the radiolunate fossa. The level of evidence urges a cautious interpretation of currently discussed hypotheses on the etiology of KD.

Prospective comparison of PCR-based vs late mRNA-based preemptive antiviral therapy for HCMV infection in patients after allo-SCT.

Human CMV (HCMV)-directed preemptive therapy has helped to improve the outcome following allo-SCT. In this study, we evaluated the safety and efficacy of a late mRNA-based (NucliSens CMV pp67) anti-HCMV treatment strategy. A prospective randomized multicenter pilot trial was performed comparing PCR-based, with late mRNA-based preemptive HCMV-directed antiviral therapy in patients after allo-SCT. In all, 133 patients were randomized in three different centers at the time of transplant, 130 of whom are evaluable. Viral screening was performed weekly. Antiviral therapy was initiated at the second consecutive positive PCR result, or at the first detection of late mRNA. The therapy was stopped if clearance of HCMV DNA or late mRNA was demonstrated after 14 days of antiviral therapy. If HCMV infection persisted, antiviral therapy was continued in a reduced dose. The median duration of antiviral therapy during the first treatment episode was 28 days for PCR-, and 19 days for mRNA-screened patients (P<0.02). However, the overall duration of antiviral therapy, as well as the incidence of HCMV disease and the OS at day 100 after transplantation was comparable between the two study groups. We conclude that late mRNA-based anti-HCMV therapy may show comparable safety and efficacy with PCR-based therapy in patients after allo-SCT.

Effect of water management, tillage options and phosphorus status on arsenic uptake in rice.

High arsenic (As) concentrations in soil may lead to elevated concentrations of arsenic in agricultural products. Field experiments were conducted to examine the effects of water management (WM) and Phosphorus (P) rates on As uptake, rice growth, yield and yield attributes of winter (boro) and monsoon (aman) rice in an As contaminated soil-water at Gobindagonj, Gaibandha, Bangladesh in 2004 and 2005. Significantly, the highest average grain yields (6.88±0.07 t ha(-1) in boro 6.38±0.06 t ha(-1) in aman) were recorded in permanent raised bed (PRB; aerobic WM: Eh=+360 mV) plus 100% P amendment. There was a 12% yield increase over conventional till on flat (CTF; anaerobic WM: Eh=-56 mV) at the same P level. In boro, the As content in grain and As content in straw were about 3 and 6 times higher in CTF compared to PRB, respectively. The highest total As content (0.646±0.01 ppm in grain and 10.93±0.19 ppm in straw) was recorded under CTF, and the lowest total As content (0.247±0.01 and 1.554±0.09 ppm in grain and straw, respectively) was recorded under PRB (aerobic WM). The results suggest that grain and straw As are closely associated in boro rice. The furrow irrigation approach of the PRB treatments consistently reduced irrigation input by 29-31% for boro and 27-30% for aman rice relative to CTF treatments in 2004 and 2005, respectively, thus reducing the amount of As added to the soil from the As-contaminated irrigation water. Yearly, 30% less As was deposited to the soil compared to CTF system through irrigation water during boro season. High As concentrations in grain and straw in rice grown using CTF in the farmers' field, and the fact that using PRB reduced grain As concentrations to value less than half of the proposed food hygiene standard.

Effects of dehydroepiandrosterone therapy on pubic hair growth and psychological well-being in adolescent girls and young women with central adrenal insufficiency: a double-blind, randomized, placebo-controlled phase III trial.

CONTEXT AND OBJECTIVE: The efficacy of oral dehydroepiandrosterone (DHEA) in the treatment of atrichia pubis and psychological distress in young females with central adrenal insufficiency is unknown. Our study aimed to evaluate this therapy. DESIGN AND PATIENTS: A total of 23 young females (mean age 18 yr, range 13-25) was enrolled in a double-blind randomized placebo-controlled trial. Inclusion criteria were ACTH deficiency plus two or more additional pituitary deficiencies, serum DHEA less than 400 ng/ml, and pubertal stage more than B2. Exclusion criteria were cerebral radiation with more than 30 Gy, tumor remission less than 1 yr, amaurosis, hypothalamic obesity, psychiatric disorders, and unstable hormone medication. INTERVENTION: Patients were randomized to placebo (n = 12) or 25 mg HPLC-purified DHEA/d (n = 11) orally for 12 months after stratification into a nontumor (n = 7) and a tumor group (n = 16). MAIN OUTCOME MEASURES: Clinical scoring of pubic hair stage was performed at 0, 6, and 12 months (primary endpoint), and psychometrical evaluation (Symptom Check-List-90-R and the Centre for Epidemiological Studies-Depression Scale) at 0 and 12 months (secondary endpoint). Androgen levels and safety parameters were measured at 0, 6, and 12 months; 24-h androgen urinary excretion rates were calculated at 0 and 12 months. RESULTS: In the placebo group, four patients dropped out because of recurrence of craniopharyngioma, manifestation of type 1 diabetes, and change of residence (n = 2); in the DHEA group, one patient dropped out because of recurrent anxiety attacks. DHEA substitution resulted in normalization of DHEA sulfate and androstanediol glucuronide morning serum levels 2 h after drug intake (P < 0.006), and of its 24 h urinary metabolite levels (P < 0.0001), placebo had no effect. Morning serum levels of androstenedione increased in the DHEA group (P < 0.02) but did not normalize. The DHEA group exhibited significant progress in pubic hair growth from Tanner stage I-III to II-V (mean: +1.5 stages), whereas the placebo group did not (relative risk 0.138; 95% confidence interval 0.021-0.914; P = 0.0046). Importantly, eight of the 10 Symptom Check-List-90-R scores, including those for depression, anxiety, and interpersonal sensitivity, and the global severity index improved in the DHEA group in comparison to the placebo group (P < 0.048). DHEA was well tolerated. CONCLUSIONS: In adolescent girls with central adrenal insufficiency, daily replacement with 25 mg DHEA orally is beneficial: atrichia pubis vanishes, and psychological well-being improves significantly.

A prospective randomized controlled trial comparing PCR-based and empirical treatment with liposomal amphotericin B in patients after allo-SCT.

We compared the efficacy and safety of empirical plus PCR-based vs empirical liposomal amphotericin B treatment after Allo-SCT. Allo-SCT recipients were randomized to receive either PCR-based preemptive therapy (group A; n=198) or empirical antifungal therapy (group B; n=211) with liposomal amphotericin B. In group A, therapy was started after one positive PCR result or after 120 h of febrile neutropenia refractory to broad-spectrum antibacterial therapy. In group B, liposomal amphotericin B was started after 120 h of refractory febrile neutropenia. Demographic and clinical characteristics were well balanced. A total of 112 (57.1%) patients in group A and 76 (36.7%) patients in group B received antifungal therapy (P<0.0001). Twelve patients in group A and 16 patients in group B developed proven invasive fungal infection (IFI). Survival curves showed better survival until day 30 when close PCR monitoring was performed (mortality 1.5 vs 6.3%; P=0.015), but there was no difference at day 100. At day 100, no difference was observed in the incidence of IFI (primary end point) and survival between the two arms. Further studies are required to assess the benefit of using PCR in patients after SCT.

Propafenone for the prevention of atrial tachyarrhythmias after cardiac surgery: a randomized, double-blind placebo-controlled trial.

We studied the efficacy of propafenone in preventing atrial tachyarrhythmias after cardiac surgery, and the possible relationships between CYP2D6 polymorphism and the efficacy, pharmacokinetics, and tolerability of propafenone. One hundred and sixty patients were randomized (double blind) to receive propafenone (n= 78) or placebo (n= 82) for 1 week after cardiac surgery. The patients who were assigned to the propafenone group received 1 mg/kg infused in 1 h, followed by a continuous infusion at a rate of 4 mg/kg/24 h until the following morning, and subsequently 450 mg/day orally until the sixth postoperative day. Thirty-seven patients completed the trial in the propafenone group and 45 in the placebo group. The frequency of occurrence of atrial tachyarrhythmia was lower in the propafenone group than in the placebo group (29.7% vs. 53.3%, P< 0.05; relative risk, 0.56). Plasma propafenone concentrations were markedly influenced by CYP2D6 genotype-derived phenotype.

Clinical and radiographic improvement of rickets in Bangladeshi children as a result of nutritional advice.

BACKGROUND: Calcium-deficiency rickets is common in south-east Bangladesh and responds to calcium supplementation. AIM: To evaluate the healing effect on active rickets of a five-component nutritional advice programme aimed at doubling dietary calcium intakes. METHODS: Forty-nine children aged <10 years with mild lower limb deformities and active rickets were followed over a period of 12 months. All were provided with a five-component nutritional advice programme advocating (i) the routine addition of 1 g limestone/kg rice, (ii) consuming small fish (including bones) instead of large ones, and (iii) daily consumption of 5 g ground sesame seeds, (iv) 100 g leafy vegetables and, if possible, (v) 100 ml of milk. RESULTS: Radiographic scores improved in 90% of children. The response was positively associated with age (r=0.34, n=48, p=0.01) and severity of radiographic score at baseline (r=0.85, n=49, p<0.0001). CONCLUSIONS: Despite the lack of a statistically significant association between radiographic improvement and compliance with nutritional advice, in mild calcium-deficiency active rickets, nutritional advice may be a cost-effective treatment and possibly a valuable long-term solution to the problem.

Evaluation of the COBAS Amplicor HCMV Monitor for early detection and monitoring of human cytomegalovirus infection after allogeneic stem cell transplantation.

Early diagnosis of human cytomegalovirus (HCMV) infection and the introduction of preemptive antiviral therapy have reduced HCMV-related mortality after allogeneic stem cell transplantation. A critical goal remains stratifying risk profiles and minimizing potential harm owing to antiviral overtreatment. We compared the commercially available standardized COBAS Amplicor CMV Monitor (CACM) to an in-house PCR assay, for the monitoring of HCMV infection. Seventy-two patients were surveyed by an in-house PCR of whole blood, quantitative viral load assessment by CACM and virus culture assays in a prospective and a retrospective study. A high concordance between CACM and PCR was documented. The viral load at onset correlated with the peak viral load (Spearman rank correlation R=0.634, P=0.0004). In patients developing HCMV disease, both viral loads were in trend higher (P=0.823, respectively P=0.053), and the viremic episodes longer (P=0.015), as compared to asymptomatically HCMV-infected patients. The serological pre-transplant status was the major risk factor for the development of HCMV disease, showing highest risk for seropositive patients receiving a seronegative graft, whereas donor type (related or unrelated) and graft type (bone marrow or peripheral blood mobilized stem cells) did not have an influence. HCMV infection proved to be a risk factor for the development of non-viral opportunistic infections (P=0.002).

[Quality of life assessment in Inflammatory Bowel Disease (IBD): German version of the Inflammatory Bowel Disease Questionnaire (IBDQ-D; disease-specific instrument for quality of life assessment) -- first application and comparison with international investigations]. / Lebensqualität bei chronisch entzündlichen Darmerkrankungen (CED): die deutsche Version des Inflammatory Bowel Disease Questionnaire (IBDQ-D) zur krankheitsspezifischen Lebensqualitätsmessung -- erste Anwendung und Vergleich mit anderen internationalen Fassungen.

BACKGROUND: Health-related quality of life (HRQOL) is an important outcome-parameter in health research and care. The aim of the working group Quality of Life in the Competence Network Inflammatory Bowel Disease (IBD; in the original German: "Kompetenznetz chronisch entzündliche Darmerkrankungen") is to generate instruments for assessment of HRQOL and its implementation as standards in clinical trials, health care and research in IBD. METHODS: The Inflammatory Bowel Disease Questionnaire (IBDQ) is an international validated disease specific instrument for HRQOL-assessment. A German version of the IBDQ was elaborated and tested in 415 outpatients with Crohn's disease (CD, n = 306) and ulcerative colitis (UC, n = 109). The aim of the study was to compare the results of HRQOL-assessment (IBDQ-D) with international investigations, to correlate HRQOL results with disease activity and to preform a pretest of psychometric properties. RESULTS: International data suggest that the IBDQ-D is a suitable instrument for HRQOL-assessment in CD and UC. For both disease a statistically significant negative correlation with disease activity was found. Tested psychometric properties do not suggest that a revision of the IBDQ-D is required. The IBDQ-D offers the HRQOL-assessment as an primary or secondary outcome in clinical trials in IBD in Germany.

Metastatic seminoma treated with either single agent carboplatin or cisplatin-based combination chemotherapy: a pooled analysis of two randomised trials.

To study the role of single agent carboplatin chemotherapy in patients with metastatic seminoma based on the data from two randomised trials. In subgroup analyses in patients with different disease characteristics, the outcome treated with either single agent carboplatin or cisplatin-based combination chemotherapy was compared. Individual patient data from two randomised European trials involving patients with metastatic seminoma were gathered. The primary endpoint for all analyses was progression-free survival. The source data of 361 patients, 184 treated with cisplatin-based combinations and 177 treated with carboplatin single agent therapy, were entered into the analysis. Patient characteristics were comparable among the cisplatin-based and the carboplatin single agent treated patient groups with lymph nodes and lungs being the most frequent metastatic sites in 92 and 8% of patients, respectively. Overall, patients treated with single agent carboplatin had an inferior 5-year overall (89 and 94%; P=0.09) and progression-free survival rate (72 and 92%; P< 0.0001) compared with patients receiving cisplatin-based combinations. For all investigated subgroups (based on age, prior radiation therapy, metastatic sites), carboplatin single agent therapy was found to be inferior to cisplatin-based combination chemotherapy. In conclusion, carboplatin single agent therapy cannot be recommended as standard treatment for any patient subgroup with advanced metastatic seminoma and cisplatin-based combination regimens remain the standard of care.

Para-aortic irradiation for stage I testicular seminoma: results of a prospective study in 675 patients. A trial of the German testicular cancer study group (GTCSG).

A prospective nonrandomised trial was performed in order to evaluate tumour control and toxicity of low-dose adjuvant radiotherapy in stage I seminoma with treatment portals confined to the para-aortic lymph nodes. Between April 1991 and March 1994, 721 patients were enrolled for the trial by 48 centres in Germany. Patients with pure seminoma and no evidence of lymph node involvement or distant metastases received 26 Gy prophylactic limited para-aortic radiotherapy. Disease-free survival at 5 years was the primary end point. With a median follow-up of 61 months, 675 patients with follow-up investigations were evaluable for this analysis. Kaplan-Meier estimates of disease-free and disease-specific survival were 95.8% (95% CI: 94.2-97.4) and 99.6% (95% CI: 99.2-100%) at 5 years and 94.9% (95% CI: 92.5-97.4%) and 99.6% (95% CI: 99.2-100%) at 8 years, respectively. A total of 26 patients relapsed. All except two were salvaged from relapse. In all, 21 recurrences were located in infradiaphragmatic lymph nodes without any 'in-field' relapse. Nausea and diarrhoea grade 3 were observed in 4.0 and 1.0% of the patients, respectively. Grade 3 late effects have not been observed so far. The results of our trial lend further support to the concept of limited para-aortic irradiation as the recently defined new standard of radiotherapy in stage I seminoma. There is no obvious compromise in disease-specific or disease-free survival compared to more extensive hockey-stick portals, which were used as standard portals at the time this study was initiated.

Questions on life satisfaction (FLZM) in inflammatory bowel disease.

BACKGROUND AND AIMS: When assessing quality of care the outcome in terms of quality of life (QOL) is of major significance. This study examined QOL in IBD outpatients and the contribution of individual expectations and various other factors including disease activity. PATIENTS AND METHODS: The study included 306 outpatients with Crohn's disease and 109 with ulcerative colitis (UC). General and health-related QOL was quantified using the instrument Questions on Life Satisfaction(Modules). Disease activity was assessed by a questionnaire. Data were compared with a normal population sample. RESULTS: Life satisfaction scores on general items and on health-related items were significantly lower than in a control sample (60.5+/-37.3 and 74.4+/-41.5, respectively) among both CD patients (54.3+/-33.2, 59.1+/-38.8) and UC patients (45.4+/-34.0, 52.1+/-40.7). Scores were significantly related to severity of disease activity. IBD patients attributed particular importance to health-related issues. CONCLUSION: Both health-related and general life satisfaction is compromised in IBD outpatients, and health-related topics have major impact. Not surprisingly, inflammatory activity compromises QOL, which underlines the importance of anti-inflammatory strategies. The importance attributed to health-related features is higher in IBD patients than in the normal population.
