PURPOSE To evaluate prognostic factors for relapse-free survival (RFS) and overall survival (OS) and to assess the impact of different postremission therapies in adult patients with core binding factor (CBF) acute myeloid leukemias (AML). PATIENTS AND METHODS Individual patient data-based meta-analysis was performed on 392 adults (median age, 42 years; range, 16 to 60 years) with CBF AML (t(8;21), n = 191; inv(16), n = 201) treated between 1993 and 2002 in prospective German AML treatment trials. RESULTS RFS was 60% and 58% and OS was 65% and 74% in the t(8;21) and inv(16) groups after 3 years, respectively. For postremission therapy, intention-to-treat analysis revealed no difference between intensive chemotherapy and autologous transplantation in the t(8;21) group and between chemotherapy, autologous, and allogeneic transplantation in the inv(16) group. In the t(8;21) group, significant prognostic variables for longer RFS and OS were lower WBC and higher platelet counts; loss of the Y chromosome in male patients was prognostic for shorter OS. In the inv(16) group, trisomy 22 was a significant prognostic variable for longer RFS. For patients who experienced relapse, second complete remission rate was significantly lower in patients with t(8;21), resulting in a significantly inferior survival duration after relapse compared with patients with inv(16). CONCLUSION We provide novel prognostic factors for CBF AML and show that patients with t(8;21) who experience relapse have an inferior survival duration.

BACKGROUND Preoperative chemotherapy improves survival in patients with stage III non-small-cell lung cancer (NSCLC) amenable to resection. We aimed to assess the additional effect of preoperative chemoradiation on tumour resection, pathological response, and survival in these patients. METHODS Between Oct 1, 1995, and July 1, 2003, patients with stage IIIA-IIIB NSCLC and invasive mediastinal assessment from 26 participating institutions of the German Lung Cancer Cooperative Group (GLCCG) were randomly assigned to one of two treatment groups. The intervention group were scheduled to receive three cycles of cisplatin and etoposide, followed by twice-daily radiation with concurrent carboplatin and vindesine, and then surgical resection (those with positive resection margins or unresectable disease were offered further twice-daily radiotherapy). The control group were scheduled to receive three cycles of cisplatin and etoposide, followed by surgery, and then further radiotherapy. The primary endpoint was median progression-free survival (PFS) in patients eligible for treatment after randomisation. Secondary endpoints in patients eligible for treatment after randomisation were overall survival (OS) and the proportion of patients undergoing surgery. Secondary endpoints in patients with tumour resection were the proportion with negative resection margins, the proportion with complete resection, the proportion with histopathological response, and the proportion with mediastinal downstaging. Additionally, exploratory (not prespecified) post-hoc analyses in terms of PFS and OS were done on patients not amenable to resection and on further subgroups of patients undergoing resection. Analyses were by intention to treat. This trial is registered on the ClinicalTrials.gov website, number NCT 00176137. FINDINGS 558 patients were randomly assigned. 34 patients did not meet inclusion criteria and were excluded. Of 524 eligible patients, 142 of 264 (54%) in the interventional group and 154 of 260 (59%) in the control group underwent surgery; 98 of 264 (37%) and 84 of 260 (32%) underwent complete resection. In patients with complete resection, the proportion of those with mediastinal downstaging (45 of 98 [46%] and 24 of 84 [29%], p=0.02) and pathological response (59 of 98 [60%] and 17 of 84 [20%], p<0.0001) favoured the interventional group. However, there was no difference in PFS (primary endpoint) between treatment groups-either in eligible patients (median PFS 9.5 months, range 1.0-117.0 [95% CI 8.3-11.2] vs 10.0 months, range 1.0-111.0 [8.9-11.5], 5-year PFS 16% [11-21] vs 14% [10-19], hazard ratio (HR) 0.99 [0.81-1.19], p=0.87), in those undergoing tumour resection, or in patients with complete resection. In both groups, 35% of patients undergoing surgery received a pneumonectomy (50/142 vs 54/154). In patients receiving a pneumonectomy, treatment-related mortality increased in the interventional group compared with the control group (7/50 [14%] vs 3/54 [6%]). INTERPRETATION In patients with stage III NSCLC amenable to surgery, preoperative chemoradiation in addition to chemotherapy increases pathological response and mediastinal downstaging, but does not improve survival. After induction with chemoradiation, pneumonectomy should be avoided. FUNDING German Cancer Aid (Bonn, Germany).

PURPOSE To identify risk factors for induction success and overall survival (OS) and relapse-free survival (RFS) and to evaluate the impact of allogeneic stem-cell transplantation (alloSCT) in adult patients up to 60 years old with acute myeloid leukemia (AML) and reciprocal translocations involving chromosome band 11q23 [t(11q23)]. PATIENTS AND METHODS An individual patient data-based meta-analysis was performed on 180 adult patients with AML and t(11q23). These patients were identified by cytogenetics and/or molecular techniques and treated within eight prospective multicenter trials of the German AML Intergroup. The median follow-up time was 53 months. RESULTS Complete remission rate was 71%. Favorable factors for induction success were the presence of a t(9;11), t(11q23) as a sole aberration, and de novo leukemia. OS rate at 4 years was 29%. Translocations other than t(9;11), platelets less than the median, secondary leukemia, and peripheral blasts greater than the median were adverse risk factors for OS. RFS rate at 4 years was 29%. The presence of a t(6;11) and peripheral blasts greater than the median had a negative impact on RFS. Three risk groups for OS and RFS could be defined by the combination of these factors with 4-year OS rates of 50%, 28%, and 5% and 4-year RFS rates of 37%, 26%, and 5%. An alloSCT from matched related or unrelated donors in first complete remission was beneficial, especially in t(6;11)-negative patients. CONCLUSION Risk stratification of AML patients with reciprocal translocations of chromosome band 11q23 is feasible based on the translocation partner and clinical parameters.

Abnormalities of the short arm of chromosome 12 (12p) are found in about 5% of acute nonlymphocytic leukaemias (ANLL) and myelodysplastic syndromes (MDS). They are described to be characteristic of secondary leukaemias, especially after prior mutagenic exposure, and to be associated with a poor prognosis. In our series of 59 patients with 12p abnormalities and ANLL or MDS, exposure to genotoxic agents was proven only in five patients, but in 13/44 patients ANLL evolved from an MDS. Patients with a small deletion del(12)(p11.2p13) having a mild clinical course were distinguished from those with a large del(12)(p11.2), additional chromosomal anomalies, and a poor clinical course. Among the 31 patients with translocations or dicentric chromosomes involving 12p, a group of eight with t/dic(12;13) was the most frequent and was associated with a poor prognosis. The clinical outcome was adverse in the majority of patients with complex karyotype abnormalities, but in some patients a milder clinical course seems likely. A new, hitherto undescribed, abnormality in an MDS case with a duplication dup(12)(p11.2p13) was the amplification of the signal of the yeast artificial chromosome (YAC) clone 964c10 (D12S736). In 38 cases with deletions or unbalanced translocations/dicentrics one YAC signal was lost. Five patients with balanced translocations demonstrated breakpoints within the YAC, containing the ETV6 (TEL) gene. The breakpoints were telomeric to the YAC 964c10 in seven cases and centromeric in one patient.

Summary Background  In 2005, a scoring system (CLASI, Cutaneous Lupus Erythematosus Disease Area and Severity Index) was developed for patients with cutaneous lupus erythematosus (CLE) to assess disease ‘activity’ and ‘damage’. However, the CLASI does not give an accurate assessment of the severity in all disease subtypes.

Quality of life (QL) was evaluated in 101 patients with AML undergoing intensive and prolonged treatment at 12 sequential time points by using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C 30 questionnaire and the profile of mood states scale (POMS). For those patients having completed the course of inpatient treatment (n=37), QL improved from the beginning of chemotherapy to the end of inpatient treatment. Patients who subsequently went off protocol did not differ significantly in their self-assessed QL when compared with patients who completed therapy. Fatigue was more closely related to QL than nausea/emesis or appetite loss, but did not correlate with hemoglobin levels.

Background The impact on quality of life of allogeneic stem cell transplantation or conventional chemotherapy in patients with acute myeloid leukemia remains unclear, mainly because of a lack of studies with long-term follow-up. The German AML-Intergroup, therefore, initiated a survey on quality of life of patients with a relapse-free survival of at least 5 years after first-line treatment. Design and Methods The EORTC Quality of Life Core Questionnaire (QLQ-C30), supplemented by information on self-assessed concomitant diseases, late treatment effects, and demographics was used. The questionnaire was returned by 419 of 818 patients (51.2%) identified by six study groups. The patients’ median age at diagnosis was 42 years, and the median follow-up period was 8 years. One hundred and seventy patients were treated with stem cell transplantation (121 allogenic, 49 autologous) in first complete remission; the other 249 patients were treated with conventional chemotherapy. Results The ECOG activity index revealed normal activity in 45% vs. 60% of the patients in the allogeneic stem cell transplantation vs. conventional chemotherapy groups, respectively and disabled person status in 60% vs. 35%. All QLQ-C30 functions, except physical functioning and pain, were poorer in allogeneic stem cell transplantation patients. Problems in leisure-time activities, social life, and financial management, sexual limitations and adverse effects were significantly more frequent in patients after allogeneic stem cell transplantation than after conventional chemotherapy. Multivariate logistic regression models on global health status revealed concomitant disease, age >45 years, and allogeneic stem cell transplantation as significant risk factors. Conclusions These results indicate that, compared to conventional chemotherapy, allogeneic stem cell transplantation has a significantly worse long-term impact on quality of life. This needs to be considered when treatment options are discussed.

BACKGROUND Medical treatment for diabetic retinopathy could have an important role in prevention of complications such as visual loss. We aimed to assess the effect of calcium dobesilate on occurrence of diabetic macular oedema. METHODS We undertook a randomised, double-blind, placebo-controlled, multicentre study in 40 centres in 11 countries. We enrolled outpatients with adult-onset type 2 diabetes and mild-to-moderate non-proliferative diabetic retinopathy, and randomly allocated them via sealed envelopes either calcium dobesilate (1500 mg per day) or placebo. The primary endpoint was development of clinically significant macular oedema (CSME) within a follow-up period of 5 years. Patients who dropped out of the study early were censored. Analysis was by intention to treat. FINDINGS We enrolled 635 patients. 324 were randomly allocated calcium dobesilate and 311 were assigned placebo. In the calcium dobesilate group, 86 patients developed CSME compared with 69 in the placebo group. Accounting for censored cases, estimated cumulative 5-year CSME probability was 35% and 28%, respectively (hazard ratio 1.32, 95% CI 0.96-1.81; p=0.0844). Adverse events did not differ between treatment groups (78 [24%] on calcium dobesilate and 90 [29%] with placebo). No relevant drug-related complications were noted. Nine patients (3%) died in the calcium dobesilate group and eight (3%) deaths were recorded on placebo. INTERPRETATION Calcium dobesilate did not reduce the risk of development of CSME.

OBJECTIVES. The aim of this investigation was to identify risk factors for being found with the head covered in sudden infant death syndrome cases and determine whether head covering was likely to be an agonal event or potentially part of the causal pathway in some cases. By using the data from 2 sudden infant death syndrome case-control studies, consistency of the findings could be assessed. METHODS. Two case-control studies were assessed: (1) the New Zealand Cot Death Study (1987–1990, 393 sudden infant death syndrome cases) and (2) a German SIDS case-control study (1998–2001, 333 sudden infant death syndrome cases). RESULTS. The proportion of sudden infant death syndrome cases in which infants were found with their head covered was 15.6% in the New Zealand study and 28.1% in the German study. Being found with head covering was associated with older infant age. In both studies, being found with head covering was associated with being very sweaty when found. Head covering was also associated with the incidence and severity of thymic petechiae in both studies. Both the position in which the child was placed to sleep and the position in which the child was found were not associated with head covering. CONCLUSIONS. The finding that sudden infant death syndrome cases in which infants were found with their heads covered were often very sweaty suggests that head covering was not an agonal event and that it preceded the death and may have been causally related to the death. Infants who were found with their head covered were older, which probably reflects motor development.
