Abstract
Abstract
Adjuvant tamoxifen treatment provides benefit for millions of women with estrogen receptor positive breast cancer; however, up to 50% of patients experience distant or local recurrence or even die. Tamoxifen resistance is contributed to by host and tumor associated factors and the latter has been particularly attributed to adaptive changes of the tumor involving the regulation of cellular pathways associated with growth, proliferation and apoptosis. Recently, microRNA expression signatures have been appreciated as useful tools to improve the classification of tumors into subtypes and the assessment of tumor heterogeneity. However it is not clear to what extend microRNA signatures derived from the primary tumor can predict treatment outcome. Here we test the hypothesis that distinct microRNAs expressed in the primary tumor can predict the onset of local and distant recurrence following adjuvant tamoxifen. We investigated 115 patients diagnosed with ER positive breast cancer at the Robert Bosch Hospital, Stuttgart, Germany, who had received adjuvant tamoxifen, and had a median follow up of 9.23 years (range: 0.21 - 19.96 years). We compared tumor microRNA expression profiles of 6 patients who developed recurrence under tamoxifen with expression profiles of 6 patients who stayed recurrence-free. Matching of patients was based on age at diagnosis, year of surgery and major histopathological parameters. Candidate microRNAs were identified by global microRNA expression profiling using GeneChip miRNA 2.0 arrays (Affymetrix). Different expression of microRNAs was validated using real-time PCR in 103 tumor samples. We identified miR-126 and miR-375 to be expressed at higher levels in tumors of patients with a lower risk of recurrence (p = 0.0003 and p = 0.0081, respectively). Receiver operator characteristics (ROC) were calculated to further validate their values for predicting breast cancer relapse. The area under the curve (AUC) for miR-126 was 0.6838 (p = 0.0006) and 0.6450 (p = 0.0071) for miR-375, respectively. Kaplan-Meier survival analyses showed that a higher expression of miR-126 and/or miRNA-375 in the patients primary tumor was associated with longer relapse-free time (p = 0.0024 and p = 0.0351, respectively). Our data suggest that miR-126 and miR-375 are promising candidates for further evaluation as tamoxifen outcome predictors in ER-positive breast cancer.

Abstract
We used hard X-ray scanning microscopy with ptychographic coherent diffraction contrast to image a front-end processed passivated microchip fabricated in 80 nm technology. No sample preparation was needed to image buried interconnects and contact layers with a spatial resolution of slightly better than 40 nm. The phase shift in the sample is obtained quantitatively. With the additional knowledge of the elemental composition determined in parallel by X-ray fluorescence mapping, quantitative information about specific nanostructures is obtained. A significant enhancement in signal-to-noise ratio and spatial resolution is achieved compared to conventional hard X-ray scanning microscopy.

Abstract
8573 Background: Multiple translational efforts in HD are actively investigating augmentation of the anti-tumor immune response by stimulating cytotoxic T lymphocytes (CTL) against tumor-associated EBV antigens. It has previously been believed that this therapeutic strategy and presence of EBV-specific CTLs are limited to EBV-positive HD. Here, we challenge this belief by characterizing EBV-specific CTL responses in EBV-negative HD. Methods: Among 52 consecutive patients with EBV-negative HD, CTL responses to latent antigens (LMP2, LMP2a) and lytic antigens (BMLF, BRLF) were serially assessed at diagnosis, during chemotherapy, and throughout followup for 2 years by IFN-γ Elispot and flow cytometric tetramer analysis. Results: We detected weak EBV-specific responses to both lytic and latent antigens by IFN-γ Elispot among patients with EBV-negative HD. Response to lytic antigen, BMLF1, was more robust in function and size among healthy donors compared to patients as determined by IFN-γ Elispot and flow cytometry of BMLF1-tetramer positive, CD8 T cells. Chemoradiotherapy was associated temporally with an initial decrease in LMP2A- and BMLF1-specific responses during the first 5–15 weeks of treatment, which subsequently became more robust 20–50 weeks after diagnosis, 2 to 4-fold greater compared to response at diagnosis. At final follow-up (24 months), increases in both lytic (2.6-fold) and latent (2.5-fold) CTL responses were observed with robustness of lytic-specific response equivalent to healthy controls. No significant change in control peptide response was observed. Conclusions: We confirm evidence of EBV-specific CTLs in patients with EBV-negative HD and provide the first report of dynamic variance in this population during treatment, challenging prior belief that patients with HD remain immunodeficient following therapy and arguing that the clinical significance of EBV-specific immune responses in EBV-negative HD should be further investigated.

Abstract
We have previously reported on the relevance of the prevalence of CD44(+)/CD24(-/low) cells in primary breast tumors. To study regulation of CD24, we queried a number of publicly available expression array studies in breast cancer cells and found that CD24 was downregulated upon estrogen treatment. We confirmed this estrogen-mediated repression of CD24 mRNA by quantitative real-time PCR in MCF7, T47D and ZR75-1 cells. Repression was also seen at the protein level as measured by flow cytometry. CD24 was not downregulated in the ER alpha negative MDA-MB-231 cells suggesting that ER alpha was necessary. This was further confirmed by ER alpha silencing in MCF7 cells resulting in increased CD24 levels and by reintroduction of ER alpha into C4-12 cells resulting in decreased CD24 levels. Estrogen treatment did not alter half-life of CD24 mRNA and new protein synthesis was not essential for repression, suggesting a primary transcriptional effect. Histone deacetylase inhibition by Trichostatin A completely abolished the repression, but decrease of the ER alpha corepressors NCoR, LCoR, RIP140, silencing mediator of retinoid and thyroid hormone receptors, SAFB1 and SAFB2 by siRNA or overexpression of SAFB2, NCoR and silencing mediator of retinoid and thyroid hormone receptors had no effect. In silico promoter analyses led to the identification of two estrogen responsive elements in the CD24 promoter, one of which was able to bind ER alpha as shown by electrophoretic mobility shift assay and chromatin immunoprecipitation assay. Together, our results show that CD24 is repressed by estrogen and that this repression is a direct transcriptional effect depending on ER alpha and histone deacetylases.

Abstract
BACKGROUND Despite several investigations, second malignancy risks (SMR) following radiotherapy alone (RT), chemotherapy alone (CT) and combined chemoradiotherapy (CRT) for Hodgkin's lymphoma (HL) remain controversial. PATIENTS AND METHODS We sought individual patient data from randomised trials comparing RT versus CRT, CT versus CRT, RT versus CT or involved-field (IF) versus extended-field (EF) RT for untreated HL. Overall SMR (including effects of salvage treatment) were compared using Peto's method. RESULTS Data for between 53% and 69% of patients were obtained for the four comparisons. (i) RT versus CRT (15 trials, 3343 patients): SMR were lower with CRT than with RT as initial treatment (odds ratio (OR) = 0.78, 95% confidence interval (CI) = 0.62-0.98 and P = 0.03). (ii) CT versus CRT (16 trials, 2861 patients): SMR were marginally higher with CRT than with CT as initial treatment (OR = 1.38, CI 1.00-1.89 and P = 0.05). (iii) IF-RT versus EF-RT (19 trials, 3221 patients): no significant difference in SMR (P = 0.28) although more breast cancers occurred with EF-RT (P = 0.04 and OR = 3.25). CONCLUSIONS Administration of CT in addition to RT as initial therapy for HL decreases overall SMR by reducing relapse and need for salvage therapy. Administration of RT additional to CT marginally increases overall SMR in advanced stages. Breast cancer risk (but not SMR in general) was substantially higher after EF-RT. Caution is needed in applying these findings to current therapies.

Abstract
Novel olfactory receptor-encoding genes that are expressed in olfactory sensory neurons arranged in a clustered pattern in the nasal epithelium, typical of the mOR262 (approved gene symbol Olfr) family, were identified. The genes share sequence motifs upstream of their transcription start sites that are highly related to those previously identified as characteristic of the mOR262 genes, suggesting that these regulatory elements may contribute to governing their unique expression pattern. Promoter analyses of genes encoding class I receptors that are expressed in the dorsal region of the epithelium revealed a different, but again common set of sequence motifs. A prominent feature of the class I gene promoters are multiple O/E-like binding sites, and O/E-type transcription factors that bind to the putative promoter region of class I OR genes were in fact identified. The findings support the concept that common elements in the promoter region of these OR genes may determine their congenic expression pattern in the epithelium.

Abstract
Genes encoding the olfactory receptors of the "OR37" subfamily of the mouse are characterized by special features including a clustered expression pattern, assembly in two distinct gene clusters, and highly conserved putative promoter motifs. Mining the rat and dog databases revealed that these two species possess highly conserved clusters of OR37 genes at two syntenic genomic loci. In a prototherian mammal, the platypus (Ornithorhynchus anatinus), none of the characteristic OR37 genes were found. Examination of a metatherian mammal, the gray short-tailed opossum (Monodelphis domestica) revealed seven canonical OR37 genes, all phylogenetically related to cluster II genes and also organized similar to cluster II of eutherian species. In addition, their 5' upstream regions comprised sequence motifs related to the putative regulatory sequences of cluster II genes. Typical cluster I OR37 genes were identified only in the eutherian mammals examined, including the evolutionary ancient anteater, wherein OR37 genes related to both clusters were present. Together, these results reveal novel information concerning the phylogenetic origin and important evolutionary steps of the mammalian-specific OR37 olfactory receptor family.

Abstract
For six mouse olfactory receptor genes from family 262 which are expressed in clustered populations of olfactory sensory neurons, the genomic as well as cDNA structures were deciphered. All genes contained several exons which in some cases were alternatively spliced. Immediately upstream of the transcription start sites, sequence motif blocks were identified that are highly conserved among olfactory receptor (OR) genes which are expressed in clustered neuronal populations. By means of electrophoretic mobility shift assays, it was demonstrated that segments of the motif block region interact with proteins extracted from nuclear fractions of the olfactory epithelium. Yeast one-hybrid screenings of an olfactory cDNA library led to the identification of a set of transcription factors that specifically bind to particular elements of the motif block region. The identified factors can be categorized into two types: One group is known to be involved in transcriptional initiation, and the second group represents factors involved in pattern formations. The identified components may contribute to govern the precise topographic expression pattern of olfactory receptor genes.

Abstract
We report a comprehensive comparative analysis of human and mouse olfactory receptor (OR) genes encoding OR37 subtypes to determine the repertoire, chromosomal organization, and relatedness of these genes. Two OR37 clusters were found in both mouse (chromosome 4) and human (chromosome 9); with five genes in cluster I and three (mouse) and seven genes (human) in cluster II. The pronounced diversity of noncoding sequence regions in both genomic loci indicates a long-term coexistence of the two clusters and the genes within the clusters. In contrast, the coding regions, particularly of genes in cluster I, showed remarkably high sequence identity, a feature quite unique for OR genes. The conservation of only the coding sequences indicates that OR37 may be under negative selection pressure and suggests that the OR37 receptor family may be tuned to recognize distinct sets of signaling molecules. A comparison of mouse and human OR37 gene clusters revealed that genes in cluster I are highly related within each species whereas genes in cluster II are highly related across species. These data reflect a unique and complex evolutionary history of the OR37 family.

Abstract
It is shown that one of the main reasons for most failures of the methods for calculating distance-dependent bond strengths is related to the distortion of the coordination polyhedra. The charge distribution (CD) method which depends on only one universal empirical parameter (contraction parameter) is modified to include: (i) an iterative calculation of the effective coordination number (ECoN), to deal with structures containing very distorted coordination polyhedra; (ii) a specific contraction parameter to treat structures containing any type of hydrogen bond; (iii) scale factors for coordination subshells, to treat structures with hetero-ligand polyhedra. The contraction parameter for the hydrogen bonds was obtained from 119 well refined structures based on neutron diffraction data. Examples of the application of the iterative charge distribution (CD-IT) are presented to show the efficiency of the new method in dealing with distorted (including hydrogen bonding) and hetero-ligand polyhedra. In particular, analysis of a series of 74 structures with pentacoordinated cations shows that deviations from overall trends are related to structure instability. The possible failure of the method with polyionic structures and 'dynamic' structures is discussed.

Abstract
PURPOSE To report the long-term survival and late toxicity data of Stage III follicular lymphoma patients treated with primary radiotherapy. METHODS AND MATERIALS Sixty-six patients with Stage III follicular small cleaved (FSC) or follicular mixed (FM) non-Hodgkin's lymphoma were treated with total lymphoid irradiation (61 patients) or whole body irradiation (5 patients) as their primary treatment modality from 1963 to 1982 at Stanford University. Adjuvant chemotherapy was given to 13 patients. RESULTS Median follow-up was 9.5 years with a range of 0.5-24.3 years. Median overall survival, cause-specific survival, freedom from relapse, and event-free survival were 9.5, 18.9, 7.1, and 5.1 years, respectively. Few initial relapses or lymphoma-related deaths were seen beyond the first decade of follow-up. Patient age and number of disease sites were the two strongest predictors of overall survival. The cohort of patients with limited Stage III disease demonstrated an 88% freedom from relapse and a 100% cause-specific survival with up to 23.5 years follow-up. CONCLUSION The long-term survival data for Stage III FSC or FM non-Hodgkin's lymphoma treated with primary radiotherapy are at least comparable and possibly better than results achieved with other therapeutic approaches. Patients with limited Stage III disease do particularly well. Whether these results are superior to an initial approach of deferred therapy until clinically indicated is currently unknown.

Abstract
The olfactory receptor multigene family is organized in clusters spread throughout the genome. In the present study, we have sequenced two subregions of the mOR37 gene cluster on mouse chromosome 4. The resulting 100 kb of sequence revealed seven odorant receptor coding regions and one gene fragment. Sequence analyses reveal that the mOR37 gene cluster may represent a rather ancient cluster. The mOR37 genes exhibit a complex intron/exon structure, and some appear to be differentially spliced. All genes in the cluster share conserved sequence motifs 5' of their putative initial exons, which represent potential binding sites for transcription factors. The clustered organization and conserved sequence motifs suggest common expression control mechanisms for these genes.

Abstract
Olfactory receptors of the OR37 subfamily are characterized by distinct sequence features and are expressed in neurons segregated in a restricted area of the olfactory epithelium. In the present study, we have characterized the complement of OR37-like genes in the mouse. Five OR37-like genes were identified. They reside within only 60kb of DNA on chromosome 4. About 70kb distant from this cluster, two additional olfactory receptor genes are located, which are members of distinct receptor subfamilies. Phylogenetic analysis demonstrated that the two physically linked receptors are closely related to the OR37 subfamily. Studies of gene expression showed that both genes are also expressed in clustered neuron populations located in the typical OR37 region of the epithelium. These data suggest the involvement of locus-dependent mechanisms for the spatial control of OR gene expression.

Abstract
Standardized guidelines for response assessment are needed to ensure comparability among clinical trials in non-Hodgkin's lymphomas (NHL). To achieve this, two meetings were convened among United States and international lymphoma experts representing medical hematology/oncology, radiology, radiation oncology, and pathology to review currently used response definitions and to develop a uniform set of criteria for assessing response in clinical trials. The criteria that were developed include anatomic definitions of response, with normal lymph node size after treatment of 1.5 cm in the longest transverse diameter by computer-assisted tomography scan. A designation of complete response/unconfirmed was adopted to include patients with a greater than 75% reduction in tumor size after therapy but with a residual mass, to include patients-especially those with large-cell NHL-who may not have residual disease. Single-photon emission computed tomography gallium scans are encouraged as a valuable adjunct to assessment of patients with large-cell NHL, but such scans require appropriate expertise. Flow cytometric, cytogenetic, and molecular studies are not currently included in response definitions. Response rates may be the most important objective in phase II trials where the activity of a new agent is important and may provide support for approval by regulatory agencies. However, the goals of most phase III trials are to identify therapies that will prolong the progression-free survival, if not the overall survival, of the treated patients. We hope that these guidelines will serve to improve communication among investigators and comparability among clinical trials until clinically relevant laboratory and imaging studies are identified and become more widely available.

Abstract
OBJECTIVE To examine the impact of two styles of educational package on practice nurses' management of obesity. SUBJECTS AND MEASURES A questionnaire was completed by 66 practice nurses concerning their obesity related beliefs and the content and style of their weight related practices before and one month after being randomly allocated to either the 'learner centred' group (who received a leaflet and were invited to attend an interactive seminar), the 'expert group' (who received the leaflet) or the control group. At the one month follow up, practice nurses were also asked to give a brief questionnaire to five consecutive patients, who they saw for weight loss advice, concerning the content and style of the consultation. After 6 months, practice nurses, and patients were sent a questionnaire about their consultation style and weight loss, respectively. RESULTS The packages had no differential effects on practice nurses' beliefs about obesity. However, practice nurses in the 'learner group' reported spending longer on their consultations and being more patient centred. Their patients rated themselves as more satisfied with the consultation and reported that they were offered calorie controlled diets less often. In contrast, practice nurses in the 'expert group' reported giving weight loss advice more frequently, being less patient centred and their patients reported greater confidence in, and likelihood of, weight loss and reported that they were more likely to be offered traditional weight loss interventions. The packages had no differential effects on patient weight. CONCLUSION Practice nurses' and patients' beliefs and behaviour and the style of their interactions can be changed by both expert and learner centred educational packages. The style of packages should be chosen in terms of both the available resources and the desired outcomes.

Abstract
We investigated the representation of T cells in patients who had been treated for Hodgkin's disease (HD). We found a marked depletion in both CD4 and CD8 naive T-cell counts that persists up to 30 years after completion of treatment. In contrast, CD4 and CD8 memory T-cell subsets recovered to normal or above normal levels by 5 years posttreatment. Thus, the previously-reported long-term deficit in total CD4 T-cell counts after treatment for HD is due to specific depletion of naive T cells. Similarly, total CD8 T-cell counts return to normal by 5 years only because CD8 memory T cells expand to higher than normal levels. These findings suggest that the treatment (mediastinal irradiation) results in a longterm dysregulation of T-cell subset homeostasis. The profound depletion of naive T cells may explain the altered T-cell function in treated patients, including the poor response to immunization after treatment for HD. Further, in some individuals, we identified expansions of unusual subsets expressing low levels of CD8. Eight-color fluorescence-activated cell sorting analyses showed that these cells largely express CD8alphaalpha homodimers and CD57, consistent with the phenotype of potentially extrathymically derived T cells. In addition, these cells, both CD4+ and CD4-, are probably cytotoxic lymphocytes, as they express high levels of intracellular perforin. In adults treated for HD, an increased activity of extrathymic T-cell differentiation may partially compensate for the loss of thymic-derived T cells.

Abstract
PURPOSE Lymphomas of the paranasal sinuses may have poorer prognoses compared with other extranodal lymphomas of the head and neck, and are not well defined as a particular clinicopathologic entity. The outcome of combined-modality therapy and central nervous system (CNS) prophylaxis has not been fully determined. PATIENTS AND METHODS We retrospectively reviewed our experience with 16 consecutive, carefully defined patients, all treated with both chemotherapy and radiotherapy. RESULTS There were 11 men and five women, mean age 52. All presented with local symptoms; 13 had stage I or II disease. Thirteen had diffuse large cell lymphoma, two diffuse mixed, and one small noncleaved. Phenotyping revealed 10 B-cell, four T-cell, and two T or natural killer (NK). Most received CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy; the order of chemotherapy and radiotherapy varied. Twelve received CNS prophylaxis. Of 12 complete responses, six relapsed, all at distant sites, and two died during initial therapy. Five-year survival was 29%, and median survival 18 months. Four of 10 B-lineage patients were relapse-free at 4 years; all six T- or T/NK-lineage patients relapsed or were dead within 6 months. Tumors of T or NK lineage often expressed CD56 and showed evidence of Epstein-Barr viral infection; otherwise, pathological features were not predictive of lineage or outcome. Neither age nor lactate dehydrogenase predicted prognosis. No complete responder recurred in the CNS as site of first relapse. CONCLUSION Despite localized stage at presentation, sinus lymphoma is an aggressive disease, characterized by distant relapse and early mortality. Combined-modality therapy with CNS prophylaxis improves outcome compared with radiotherapy alone; however, prognosis remains poor. Patients with T-lineage disease appear to have a particularly bad outcome. Autologous bone marrow transplantation should be evaluated as first-line therapy for those at high risk of relapse.

Abstract
OBJECTIVE To determine whether systemic elimination of macrophages by means of clodronate-containing liposomes counteracts inflammation and joint destruction in rats with established adjuvant arthritis (AA). METHODS Rats with AA received a total of 2.7 mg of clodronate encapsulated in liposomes in 3 intravenous doses on days 10, 11, and 12 of arthritis. Phosphate buffered saline (PBS), PBS-laden liposomes, or free clodronate were used as negative controls. Clinical, hematologic, and histopathologic signs of AA were monitored, and depletion of macrophages by clodronate-liposomes was evaluated both in the synovial membrane (SM) and in organs of the mononuclear phagocyte system (MPS). RESULTS Clodronate-laden liposomes led to significant, long-term amelioration of the clinical signs of AA, a reduction in the erythrocyte sedimentation rate (ESR), and counteraction of joint destruction, not only immediately after treatment, but also for 2 weeks thereafter. Free clodronate induced moderate clinical improvement and a significant decrease in the ESR, but only during the late phase of AA. Drug-free vesicles even aggravated the joint destruction. Clodronate-laden liposomes did not induce significant depletion of resident macrophages in the SM, but rather, in the paracortical region of popliteal lymph nodes, in the liver, and in the marginal zone and periarteriolar lymphatic sheaths of the spleen. CONCLUSION Clodronate-laden liposomes induce long-term amelioration of AA, even if administered for a brief period during the florid phase of the disease. The amelioration is paralleled by the elimination of macrophages in immunocompetent areas of the spleen and draining lymph nodes, but not locally in the SM. This suggests an influence of the treatment on the immunoregulatory rather than effector, functions of macrophages.
