Abstract
BACKGROUND The European Organization for Research and Treatment of Cancer (EORTC) QLQ-BR23 was one of the first disease-specific questionnaires developed in 1996 to assess quality of life (QoL) in patients with breast cancer (BC). However, since 1996 major changes in BC treatment have occurred, requiring an update of the EORTC BC module. This study presents the results of the phase I-III update of the QLQ-BR23 questionnaire. PATIENTS AND METHODS The update of the EORTC QLQ-BR23 module followed standard EORTC guidelines. A systematic literature review revealed 83 potential relevant QoL issues during phases I and II. After shortening the issues list and following interviews with patients and health care providers, 15 relevant issues were transformed into 27 items. The preliminary module was pretested in an international, multicentre phase III study to identify and solve potential problems with wording comprehensibility and acceptability of the items. Descriptive statistics are provided. Analyses were qualitative and quantitative. We provide a psychometric structure of the items. RESULTS The phase I and II results indicated the need to supplement the original QLQ-BR23 with additional items related to newer therapeutic options. The phase III study recruited a total of 250 patients (from 12 countries). The final updated phase III module contains a total of 45 items: 23 items from the QLQ-BR23 and 22 new items. The new items contain two multi-item scales: a target symptom scale and a satisfaction scale. The target symptom scale can be divided into three subscales: endocrine therapy, endocrine sexual and skin/mucosa scale. CONCLUSION Our work has led to the development of a new EORTC QLQ-BR45 module that provides a more accurate and comprehensive assessment of the impact of new and scalable treatments on patients' QoL. The final version of the EORTC QLQ-BR45 is currently available for use in clinical practice. The final phase IV study is underway to confirm psychometric properties of the module.

Abstract
BACKGROUND Surgeons provide patients with information before surgery, although standards of information are lacking and practice varies. The development and use of a 'core information set' as baseline information before surgery may improve understanding. A core set is a minimum set of information to use in all consultations before a specific procedure. This study developed a core information set for oesophageal cancer surgery. METHODS Information was identified from the literature, observations of clinical consultations and patient interviews. This was integrated to create a questionnaire survey. Stakeholders (patients and professionals) were surveyed twice to assess views on importance of information from 'not essential' to 'absolutely essential' using Delphi methods. Items not meeting predefined criteria were discarded after each survey and the final retained items were voted on, in separate patient and professional stakeholder meetings, to agree the core set. RESULTS Some 67 information items were identified initially from multiple sources. Survey response rates were 76·5 per cent (185 of 242) and 54·8 per cent (126 of 230) for patients and professionals respectively (first round), and over 83 per cent in both groups thereafter. Health professionals rated short-term clinical outcomes most highly (technical complications), whereas patients prioritized information related to long-term benefits. The consensus meetings agreed the final set, which consisted of: in-hospital milestones to recovery, rates of open-and-close surgery, in-hospital mortality, major complications (reoperation), milestones in recovery after discharge, longer-term eating and drinking and overall quality of life, and chances of survival. CONCLUSION This study has established a core information set for surgery for oesophageal cancer.

Abstract
OBJECTIVE The aim was to prospectively measure quality of life in patients with malignant blood disorders following stem cell transplantation (SCT) using an individualized and a standardized measure. METHODS Twenty-two consecutive patients were assessed before and one year following SCT, using a generic and disease-related version of the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) and the EORTC QLQ-C30. Results of the QLQ-C30 were compared with Swedish norm values. RESULTS A majority of the patients reported concerns related to health before as well as one year after SCT, recorded by both instruments. Mean scores produced by the SEIQoL-DW, and four scales of the EORTC QLQ-C30, showed a change over time, indicating improved quality of life one year after SCT. In comparison with Swedish norm values for the EORTC QLQ-C30, SCT recipients reported a worse functioning. CONCLUSIONS In addition to well-known disease and treatment-related problems, areas not typically included in standardized instruments were nominated in the disease-related SEIQoL-DW. Such areas included positive aspects, e.g. a changed view of life and oneself. The results support the use of the generic and disease-related SEIQoL-DW to achieve a comprehensive picture of patient's clinical situation under treatment or when recovering from illness.

Abstract
BACKGROUND Previous work highlighted a number of methodological constraints when reporting health-related quality of life (HRQOL) outcomes from randomized controlled trials (RCTs). Given this, the objective of this study was to investigate whether the quality of such HRQOL reports has improved over time. MATERIALS AND METHODS On the basis of a predefined set of criteria, 159 RCTs with a HRQOL end point, published between 1990 and 2004 were identified and analyzed. Each study was evaluated by a number of issues (e.g. sample size and industry sponsorship) and by the "minimum standard checklist for evaluating HRQOL outcomes in cancer clinical trials". RESULTS The quality of HRQOL reports, as measured by the overall checklist score, was independently related to more recently published studies (P < 0.0001). This relationship was independent of industry funded, HRQOL end point (primary versus secondary), cancer disease site, size of the study and HRQOL difference between treatment arms. While only 39.3% of studies published between 1990 and 2000 (89/159 RCTs) were identified as being probably robust, thus likely to support clinical decision making, this percentage was 64.3% for studies published after 2000 (70/159 RCTs). CONCLUSION Since we found a significant learning curve in HRQOL trial reporting since 1990, it can be expected that HRQOL data will increasingly impact on clinical decision making and treatment policies in the near future.

Abstract
Perpetual V(D)J recombinase activity involving multiple DNA double-strand break events in B-cell lineage leukemia and lymphoma cells may introduce secondary genetic aberrations leading towards malignant progression. Here, we investigated defective negative feedback signaling through the (pre-) B-cell receptor as a possible reason for deregulated V(D)J recombinase activity in B-cell malignancy. On studying 28 cases of pre-B-lymphoblastic leukemia and 27 B-cell lymphomas, expression of the (pre-) B-cell receptor-related linker molecule SLP65 (SH2 domain-containing lymphocyte protein of 65 kDa) was found to be defective in seven and five cases, respectively. SLP65 deficiency correlates with RAG1/2 expression and unremitting V(H) gene rearrangement activity. Reconstitution of SLP65 expression in SLP65-deficient leukemia and lymphoma cells results in downregulation of RAG1/2 expression and prevents both de novo V(H)-DJ(H) rearrangements and secondary V(H) replacement. We conclude that iterative V(H) gene rearrangement represents a frequent feature in B-lymphoid malignancy, which can be attributed to SLP65 deficiency in many cases.

Abstract
Pre-B lymphoblastic leukemia cells carrying a BCR-ABL1 gene rearrangement exhibit an undifferentiated phenotype. Comparing the genome-wide gene expression profiles of normal B-cell subsets and BCR-ABL1+ pre-B lymphoblastic leukemia cells by SAGE, the leukemia cells show loss of B lymphoid identity and aberrant expression of myeloid lineage-specific molecules. Consistent with this, BCR-ABL1+ pre-B lymphoblastic leukemia cells exhibit defective expression of IKAROS, a transcription factor needed for early lymphoid lineage commitment. As shown by inducible expression of BCR-ABL1 in human and murine B-cell precursor cell lines, BCR-ABL1 induces the expression of a dominant-negative IKAROS splice variant, termed IK6. Comparing matched leukemia sample pairs from patients before and during therapy with the BCR-ABL1 kinase inhibitor STI571 (Imatinib), inhibition of BCR-ABL1 partially corrected aberrant expression of IK6 and lineage infidelity of the leukemia cells. To elucidate the contribution of IK6 to lineage infidelity in BCR-ABL1+ cell lines, IK6 expression was silenced by RNA interference. Upon inhibition of IK6, BCR-ABL1+ leukemia cells partially restored B lymphoid lineage commitment. Therefore, we propose that BCR-ABL1 induces aberrant splicing of IKAROS, which interferes with lineage identity and differentiation of pre-B lymphoblastic leukemia cells.

Abstract
SLP65 represents a critical component in (pre-) B cell receptor signal transduction but is compromised in a subset of pre-B cell-derived acute lymphoblastic leukemia. Based on these findings, we investigated (i.) whether SLP65-deficiency also occurs in mature B cell-derived lymphoma and (ii.) whether SLP65-deficient B cell lymphoma cells use an alternative B cell receptor signaling pathway in the absence of SLP65. Indeed, expression of SLP65 protein was also missing in a fraction of B cell lymphoma cases. While SLP65 is essential for B cell receptor-induced Ca2+ mobilization in normal B cells, B cell receptor engagement in SLP65-deficient as compared to SLP65-reconstituted B cell lymphoma cells resulted in an accelerated yet shortlived Ca2+-signal. B cell receptor engagement of SLP65-deficient lymphoma cells involves SRC kinase activation, which is critical for B cell receptor-dependent Ca2+-mobilisation in the absence but not in the presence of SLP65. As shown by RNA interference, the SRC kinase LYN is required for B cell receptor-induced Ca2+ release in SLP65-deficient B cell lymphoma cells but dispensable after SLP65-reconstitution. B cell receptor engagement in SLP65-deficient B cell lymphoma cells also resulted in tyrosine-phosphorylation of the proliferation- and survival-related MAPK1 and STAT5 molecules, which was sensitive to silencing of the SRC kinase LYN. Inhibition of SRC kinase activity resulted in growth arrest and cell death specifically in SLP65-deficient lymphoma cells. These findings indicate that LYN can short-circuit conventional B cell receptor signaling in SLP65-deficient B cell lymphoma cells and thereby promote activation of survival and proliferation-related molecules.

Abstract
BACKGROUND As part of a larger study whose objective is to develop an abbreviated version of the EORTC QLQ-C30 suitable for research in palliative care, analyses were conducted to determine the feasibility of generating a shorter version of the 4-item emotional functioning (EF) scale that could be scored in the original metric. METHODS We used data from 24 European cancer studies conducted in 10 different languages (n = 8242). Item selection was based on analyses by item response theory (IRT). Based on the IRT results, a simple scoring algorithm was developed to predict the original 4-item EF sum scale score from a reduced number of items. RESULTS Both a 3-item and a 2-item version (item 21 'Did you feel tense?' and item 24 'Did you feel depressed?') predicted the total score with excellent agreement and very little bias. In group comparisons, the 2-item scale led to the same conclusions as those based on the original 4-item scale with little or no loss of measurement efficiency. CONCLUSION Although these results are promising, confirmatory studies are needed based on independent samples. If such additional studies yield comparable results, incorporation of the 2-item EF scale in an abbreviated version of the QLQ-C30 for use in palliative care research settings would be justified. The analyses reported here demonstrate the usefulness of the IRT-based methodology for shortening questionnaire scales.

Abstract
A study was undertaken to describe the treatment preferences and choices of patients with breast cancer, and to identify predictors of undergoing breast-conserving therapy (BCT) or mastectomy (MT). Consecutive patients with stage I/II breast cancer were eligible. Information about predictor variables, including socio-demographics, quality of life, patients' concerns, decision style, decisional conflict and perceived preference of the surgeon was collected at baseline, before decision making and surgery. Patients received standard information (n=88) or a decision aid (n=92) as a supplement to support decision making. A total of 180 patients participated in the study. In all, 72% decided to have BCT (n=123); 28% chose MT (n=49). Multivariate analysis showed that what patients perceived to be their surgeons' preference and the patients' concerns regarding breast loss and local tumour recurrence were the strongest predictors of treatment preference. Treatment preferences in itself were highly predictive of the treatment decision. The decision aid did not influence treatment choice. The results of this study demonstrate that patients' concerns and their perceptions of the treatment preferences of the physicians are important factors in patients' decision making. Adequate information and communication are essential to base treatment decisions on realistic concerns, and the treatment preferences of patients.

Abstract
AIMS To describe and assess the quality of rehabilitation of cancer survivors by occupational physicians and to relate the quality of the process of occupational rehabilitation to the outcome of return to work. METHODS One hundred occupational physicians of a cohort of cancer survivors were interviewed about return to work management. Quality of rehabilitation was assessed by means of four indicators that related to performance in knowledge of cancer and treatment, continuity of care, patients complaints, and relations at work. The cohort of patients was prospectively followed for 12 months to assess time to return to work and rate of return to work. Patients' and physicians' satisfaction with care was also assessed. The relation between performance and these outcome measures was studied in a multivariate analysis, taking into account the influence of other work and disease related factors that could potentially predict return to work. RESULTS For knowledge of cancer and treatment, only 3% had optimal performance because occupational physicians did not communicate with treating physicians. For continuity of care, patient complaints, and relations at work, performance was optimal for 55%, 78%, and 60% of the physicians respectively. After adjustment for other prognostic factors, overall physician's performance (hazard ratio (HR) 0.5, 95% CI 0.3 to 0.8) and continuity of care (HR 0.5, 95% CI 0.3 to 0.9) were related to the return to work of patients. Overall optimal performance was also related to a small but significant higher level of satisfaction with care, both for patients and physicians. CONCLUSION Quality of occupational rehabilitation of cancer survivors can be improved substantially, especially with regard to communication between physicians and continuity of care. There is a need for the development of more effective rehabilitation procedures which should be evaluated in a randomised controlled trial.

Abstract
OBJECTIVES To investigate adherence to antiretroviral therapy over 48 weeks, to investigate the association between adherence and treatment-related symptoms and to investigate the impact of adherence on virological response over 48 weeks among established predictors of treatment success. METHODS One-hundred-and-sixty HIV-1 infected protease inhibitor- and stavudine-naive patients participating in a trial of ritonavir/saquinavir versus ritonavir/saquinavir/ stavudine completed an adherence questionnaire and a symptom checklist at weeks 12, 24, 36 and 48. We calculated odds ratios between experienced symptoms and non-adherence. Regression models were used to determine predictors of HIV-1 RNA below 400 copies/ml at week 48, and of the area about the change from baseline over 48weeks (ACFB) in serum HIV-1 RNA. RESULTS The percentage of patients reporting missing medication, deviation from time schedule, and dietary prescriptions at separate time-points ranged from 12 to 15%, 32 to 35% and 17 to 22%, respectively. The percentage that changed their level of adherence during 48 weeks ranged from 29% for skipping medication to 48% for deviation from time-schedule. Experienced side-effects were associated with an increased likelihood of non-adherence. Not skipping medication was an independent predictor of both having a serum HIV-1 RNA below 400 copies/ml at week 48 and the ACFB over 48weeks in serum HIV-1 RNA. CONCLUSIONS Adherence was an independent predictor of virological response over 48 weeks. The level of adherence is variable within patients over time. This suggests the need for continued adherence monitoring in all patients as part of standard medical practice.

Abstract
Overexpression of a GTPase deficient dynamin mutant in HeLa dynK44A cells causes a block in clathrin-dependent endocytosis. When endocytosis is inhibited, these cells incorporate higher levels of [(35)S]sulfate into both cellular and secreted macromolecules and larger amounts of proteoglycans such as syndecan and perlecan are immunoprecipitated from [(35)S]sulfate-labelled lysates. Gel filtration and ion-exchange chromatography revealed that the increased [(35)S]sulfate incorporation into proteoglycans was not due to significant differences in size or density of negative charge of glycosaminoglycan chains attached to proteoglycan core proteins. On the other hand, measurements of the syndecan-1 mRNA level and of [(3)H]leucine-labelled perlecan after immunoprecipitation supported the idea that the increased [(35)S]sulfate incorporation into proteoglycans was due to a selective increase in the synthesis of proteoglycan core proteins. Interestingly, the activity of protein kinase C was increased in cells expressing mutant dynamin and inhibition of protein kinase C with BIM reduced the differences in [(35)S]sulfate incorporation between cells with normal and impaired clathrin-dependent endocytosis. Thus, the activation of protein kinase C observed upon inhibition of clathrin-dependent endocytosis may be responsible for the increased synthesis of proteoglycans.

Abstract
The European Organization for Research and Treatment of Cancer (EORTC) has taken a leading role in the development of the methodology of quality of life (QL) measurement. In the EORTC Quality of Life Study Group (QLSG) valid instruments to assess QL in a general manner and disease-specific modules have been developed to be used in oncological clinical trials. Statistical and methodological aspects of QL research are discussed. The application of QL assessments in clinical trials represents a subsequent challenge. To improve the practice of QL assessment in clinical trials an 'EORTC model' has been developed. This model requires the collaboration of liaison persons, the EORTC Cooperative Tumour Groups and the EORTC Data Centre Quality of Life Unit (QL Unit). Cooperation between these parties, protocol development and advantages and concerns of the model are mentioned in this paper. Finally, suggestions for improvement are proposed.

Abstract
A revision of the Quality of Life Questionnaire (QLQ-C30) of the European Organization for Research and Treatment of Cancer (EORTC) was undertaken to improve low internal consistency estimates (Cronbach's alpha) and content validity for the role functioning scale and a conceptual difficulty (undue emphasis on physical functioning) in the global quality of life (QOL) scale. The role functioning items were reworded and a four-category response format was substituted for the previous dichotomous format. A new item asking about 'overall health' was substituted for the 'overall physical condition' item in the global QOL domain. The original and new versions were tested at three time points in a total of 1,181 patients with cancer in Canada (n = 696) and the Netherlands (n = 485). In both samples there was a marked improvement in internal consistency for the role functioning scale (Cronbach's alpha s ranging from 0.78-0.88) in the new version. In the global QOL scale, the substitution of the new item for the previous one did not alter internal consistency (Cronbach's alpha's ranging from 0.81-0.92). The revised versions of the role functioning and global QOL domains have been incorporated into the QLQ-C30 (version 2.0).
