Abstract
Hodgkin lymphoma, even in advanced-stage, is a highly curable malignancy, but treatment is associated with short-term toxicity and long-term side effects. Early predictive markers are required to identify those patients who do not require the full-length standard therapy (and thus qualify for therapy de-escalation) and those patients who will not be cured by standard therapy (and thus qualify for therapy escalation). Multiple trials have assessed the value of 18 F-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) after a few cycles of chemotherapy (also known as 'interim FDG-PET') in predicting outcome in advanced-stage Hodgkin lymphoma. Furthermore, multiple interim FDG-PET-adapted trials, in which patients with positive interim FDG-PET scans are assigned to escalated therapies, and patients with negative interim FDG-PET scans are assigned to de-escalated therapies, have recently been published or are currently ongoing, with generally heterogeneous results. The present article reports the currently available evidence (and controversies) on the prognostic value of interim FDG-PET in advanced-stage Hodgkin lymphoma in patients with positive and negative interim FDG-PET findings following continuation of standard chemotherapy or escalated/de-escalated therapy.

Abstract
INTRODUCTION Hodgkin lymphoma is an effectively treated malignancy, yet 20% of patients relapse or are refractory to front-line treatments with potentially fatal outcomes. Early detection of poor treatment responders is crucial for appropriate application of tailored treatment strategies. Tumour metabolic imaging of Hodgkin lymphoma using visual (qualitative) 18-fluorodeoxyglucose positron emission tomography (FDG-PET) is a gold standard for staging and final outcome assessment, but results gathered during the interim period are less accurate. Analysis of continuous metabolic-morphological data (quantitative) FDG-PET may enhance the robustness of interim disease monitoring, and help to improve treatment decision-making processes. The objective of this review is to compare diagnostic test accuracy of quantitative versus qualitative interim FDG-PET in the prognostication of patients with Hodgkin lymphoma. METHODS The literature on this topic will be reviewed in a 3-step strategy that follows methods described by the Joanna Briggs Institute (JBI). First, MEDLINE and EMBASE databases will be searched. Second, listed databases for published literature (MEDLINE, Tripdatabase, Pedro, EMBASE, the Cochrane Central Register of Controlled Trials and WoS) and unpublished literature (Open Grey, Current Controlled Trials, MedNar, ClinicalTrials.gov, Cos Conference Papers Index and International Clinical Trials Registry Platform of the WHO) will be queried. Third, 2 independent reviewers will analyse titles, abstracts and full texts, and perform hand search of relevant studies, and then perform critical appraisal and data extraction from selected studies using the DATARI tool (JBI). If possible, a statistical meta-analysis will be performed on pooled sensitivity and specificity data gathered from the selected studies. Statistical heterogeneity will be assessed. Funnel plots, Begg's rank correlations and Egger's regression tests will be used to detect and/or correct publication bias. ETHICS AND DISSEMINATION The results will be disseminated by publishing in a peer-reviewed journal. Ethical assessment will not be needed; only existing sources of literature will be searched. TRIAL REGISTRATION NUMBER CRD42016027953.

Abstract
UNLABELLED Treatment and outcome of Hodgkin lymphoma (HL) are the true success story of modern medicine. The data from the developing countries on long-term outcome of patients with HL is sparse. AIMS Primary objective is to assess the progression-free survival (PFS). Secondary objective are overall survival (OS) and toxicities. SETTINGS AND DESIGN This is a retrospective analysis from the case records from a single institution. MATERIALS AND METHODS Institutional Ethical Committee approval was obtained. Between January 1991 and December 2010, 301 patients (age ≥18 years) underwent treatment at our institution. STATISTICAL ANALYSIS Kaplan-Meyer curves were used to calculate the PFS and OS. RESULTS The median age at presentation was 36 years, range from 19 to 75 years. The male to female ratio was 2.9:1. Seventy-five percent of patients had B symptoms. Majority presented in advanced stage (Stage III and IV) disease (64.7%). Mixed cellularity (74.4%) was the most common histology, followed by nodular sclerosis (13.9%). The most common chemotherapy regimen used was ABVD (61%). CONCLUSIONS Median follow-up of the cohort was 18.5 months (range 2-225). PFS and OS rate at 5 years is 66.3% and 79.7% respectively.

Abstract
Diffuse large B-cell lymphoma (DLBCL) demonstrates significant racial differences in age of onset, stage, and survival. To examine whether population-specific models improve prediction of outcomes for African-American (AA) patients with DLBCL, we utilized Surveillance, Epidemiology, and End Results data and compared stratification by the international prognostic index (IPI) in general and AA populations. We also constructed and compared prognostic models for general and AA populations using multivariable logistic regression (LR) and artificial neural network approaches. While the IPI adequately stratified outcomes for the general population, it failed to separate AA DLBCL patients into distinct risk groups. Our AA LR model identified age ≥ 55 (odds ratio 0.45, [95% CI: 0.36, 0.56], male sex (0.75, [0.60, 0.93]), and stage III/IV disease (0.43, [0.34, 0.54]) as adverse predictors of 5-year survival for AA patients. In addition, general-population prognostic models were poorly calibrated for AAs with DLBCL, indicating a need for validated AA-specific prognostic models.

Abstract
Treatment resistance occurs in approximately 30% of individuals with schizophrenia and is commonly treated with clozapine. Nodular sclerosing Hodgkin's lymphoma is a subtype of Hodgkin's lymphoma predominantly affecting those under 50 years of age. In this case report, an individual with treatment-resistant schizophrenia developed nodular sclerosing Hodgkin's lymphoma and is treated with concurrent clozapine and systemic chemotherapy. The aim of this case report is to act as guidance for clinicians and to outline the difficulties of treating individuals with psychiatric illness under the Mental Capacity Act 2005 when the proposed treatment could lead to high levels of morbidity and mortality.

Abstract
BACKGROUND Histologic subtypes of classical Hodgkin lymphoma [cHL; e.g., nodular sclerosis, mixed cellularity, not otherwise specified (NOS)] are epidemiologically and prognostically distinctive. Therefore, unexplained, ongoing incidence rate declines for mixed cellularity and increases for NOS require examination. METHODS We analyzed detailed histology-specific Hodgkin lymphoma incidence rates in 1992 through 2011 U.S. SEER data (n = 21,372) and reviewed a regional subset of 2007 through 2011 NOS pathology reports for insight into diagnostic practices. RESULTS cHL rates were stable until 2007, then decreased for whites [annual percent change (APC) and 95% confidence interval (CI), -3.6% (-5.6% to -1.5%)]. Nodular sclerosis rates declined after 2007 by 5.9% annually, with variation by gender, age, and race/ethnicity. In 1992 through 2011, mixed cellularity rates declined [APC -4.0% (-4.7% to -3.3%)], whereas NOS rates rose [5.3% (4.5%-6.2%)] overall and in most patient groups. The 2007-2011 NOS age-specific rates were more similar to mixed cellularity rates for 1992-1996 than 2007-2011. Trends in combined rates were minimal, supporting increasing misclassification of mixed cellularity, lymphocyte depletion, and specific nodular sclerosis subtypes as NOS. Eighty-eight of 165 reviewed NOS pathology reports addressed classification choice. Twenty (12.1%) justified the classification, 21 (12.7%) described insufficient biopsy material, and coders missed specific subtype information for 27 (16.4%). CONCLUSION Recent nodular sclerosis rate declines largely represent true incidence changes. Long-term rate decreases for mixed cellularity and other less common subtypes, and increases for NOS (comprising ∼30% of cHL cases in 2011), likely reflect changes in diagnostic and/or classification practice. IMPACT Diminishing histologic subtyping undermines future surveillance and epidemiologic study of Hodgkin lymphoma. Guideline-based use of excisional biopsies and more coding quality control are warranted.

Abstract
Current standard of care therapy for diffuse large B-cell lymphoma (DLBCL) cures a majority of patients with additional benefit in salvage therapy and autologous stem cell transplant for patients who relapse. The next generation of prognostic models for DLBCL aims to more accurately stratify patients for novel therapies and risk-adapted treatment strategies. This review discusses the significance of host genetic and tumor genomic alterations seen in DLBCL, clinical and epidemiologic factors, and how each can be integrated into risk stratification algorithms. In the future, treatment prediction and prognostic model development and subsequent validation will require data from a large number of DLBCL patients to establish sufficient statistical power to correctly predict outcome. Novel modeling approaches can augment these efforts.

Abstract
BACKGROUND The incidence of nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is higher among African Americans than among other races, but to the authors' knowledge, the characteristics of NLPHL in this population have not been evaluated. The authors compared clinical features, treatments, and survival of black and white patients with NLPHL using the National Cancer Data Base. METHODS The authors extracted the records of 602 black and 1950 white patients with NLPHL who were diagnosed between 1998 and 2011. Overall survival (OS) was compared using the log-rank test. RESULTS Black patients were on average younger than white patients (median age, 42 years vs 45 years; P =.0001), more often female (49% vs 29%; P<.0001), and more likely to have the axillary lymph nodes as the primary disease site (25% vs 17%; P =.0002). They also had unfavorable socioeconomic characteristics, a higher rate of no treatment in patients with early-stage disease, and a longer time to therapy initiation (median, 53.5 days vs 47 days; P<.0001). Despite this, the authors found no significant difference between the races with regard to stage distribution or survival (P =.39). OS at 7 years was 90.1% in patients with early-stage (American Joint Committee on Cancer stage IA/B, IIA) and 79.4% in patients with advanced stage (American Joint Committee on Cancer stage IIB, III/IV) NLPHL. Survival in the early stage of disease was not found to be significantly different after various treatment strategies (stratified log-rank P = .18), except that the administration of chemotherapy was associated with a better outcome in black patients (log-rank P =.011 vs P =.81 for white patients). CONCLUSIONS Differences in clinical presentation suggest the interaction of race-specific and sex-specific susceptibility factors for NLPHL. Further research is needed to elucidate these factors, and to investigate possible heterogeneous effects of treatments by race. Clinical trials comparing standard treatment strategies are unlikely to detect differences in OS among patients with early-stage NLPHL.

Abstract
Purpose The choice between combined-modality therapy (CMT) and chemotherapy alone for early-stage Hodgkin lymphoma (HL) remains controversial. Our objective was to define factors affecting treatment selection and resulting survival outcomes in the United States. Patients and Methods We identified 20,600 patients treated with CMT or chemotherapy between 2003 and 2011 from the National Cancer Data Base. Factors affecting treatment selection were studied in a mixed-effects logistic model. Survival outcomes were compared using a propensity score analysis to account for indication bias. Results Only 49.5% of patients received CMT, and this proportion steadily declined between 2003 (59.4%) and 2011 (45.2%), particularly in younger patients. Apart from classical prognostic factors (age, stage, tumor location, histology, comorbidities), treatment selection was significantly influenced by sex, black race, distance to facility, and type of insurance. Uninsured patients had the lowest odds of receiving CMT. A significant random effect related to facility-specific treatment preference was also evident. Estimated 5-year overall survival (OS) was 89.6%, and relative survival (RS) was 94.3%. After adjustment for guarantee-time and indication biases, CMT was associated with better OS (hazard ratio [HR], 0.61; 95% CI, 0.53 to 0.70) and RS (excess HR, 0.42; 95% CI, 0.33 to 0.54) than chemotherapy alone. This effect was without significant heterogeneity in subset analysis and was not sensitive to unobserved confounding. Conclusion Socioeconomic factors affect selection of curative treatments in HL. Widespread abandonment of CMT beyond circumstances sanctioned by guidelines may affect survival. Further research should focus on developing strategies that minimize toxicity and access disparities without compromising survival.

Abstract
BACKGROUND Hodgkin lymphoma (HL) is a B-cell lymphoma accounting for 10% to 15% of all lymphoma in industrialised countries. It has a bimodal age distribution with one peak around the age of 30 years and another after the age of 60 years. Although HL accounts for fewer than 1% of all neoplasms worldwide, it is considered to be one of the most common malignancies in young adults and, with cure rates of 90%, one of the most curable cancers worldwide. Current treatment options for HL comprise more- or less-intensified regimens of chemotherapy plus radiotherapy, depending on disease stage. [18F]-fluorodeoxy-D-glucose (FDG)-positron emission tomography (PET, also called PET scanning) is an imaging tool that can be used to illustrate a tumour's metabolic activity, stage and progression. Therefore, it could be used as a standard interim procedure during HL treatment, to help distinguish between individuals who are good or poor early responders to therapy. Subsequent therapy could then be de-escalated in PET-negative individuals (good responders) or escalated in those who are PET-positive (poor responders). It is currently unknown whether such response-adapted therapeutic strategies are of benefit to individuals in terms of overall and progression-free survival, and the incidence of long-term adverse events (AEs). OBJECTIVES To assess the effects of interim [18F]-FDG-PET imaging treatment modification in individuals with HL. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; latest issue) and MEDLINE (from 1990 to September 2014) as well as conference proceedings (American Society of Hematology; American Society of Clinical Oncology; European Hematology Association; and International Symposium on Hodgkin Lymphoma) for studies. Two review authors independently screened search results. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing FDG-PET-adapted therapy with non-adapted treatment in individuals with previously untreated HL of all stages and ages. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the quality of trials. As none of the included studies provided HRs for OS, we described risk ratios (RRs) for this outcome and did not pool the data. As an effect measure we used hazard ratios (HRs) for progression-free survival (PFS). We described RRs for the dichotomous data on AEs. We also calculated 95% confidence intervals (CIs). MAIN RESULTS Our search strategies led to 308 potentially relevant references. From these, we included three studies involving 1999 participants. We judged the overall potential risk of bias as moderate. The studies were reported as RCTs; blinding was not reported, but given the study design it is likely that there was no blinding. One study was published in abstract form only; hence, detailed assessment of the risk of bias was not possible.Two trials compared standard treatment (chemotherapy plus radiotherapy) with PET-adapted therapy (chemotherapy only) in individuals with early-stage HL and negative PET scans. The study design of the third trial was more complex. Participants with early-stage HL were divided into those with a favourable or unfavourable prognosis. They were then randomised to receive PET-adapted or standard treatment. Following a PET scan, participants were further divided into PET-positive and PET-negative groups. To date, data have been published for the PET-negative arms only, making it possible to perform a meta-analysis including all three trials.Of the 1999 participants included in the three trials only 1480 were analysed. The 519 excluded participants were either PET-positive, or were excluded because they did not match the inclusion criteria.One study reported no deaths. The other two studies reported two deaths in participants receiving PET-adapted therapy and two in participants receiving standard therapy (very-low-quality evidence). Progression-free survival was shorter in participants with PET-adapted therapy (without radiotherapy) than in those receiving standard treatment with radiotherapy (HR 2.38; 95% CI 1.62 to 3.50; P value < 0.0001). This difference was also apparent in comparisons of participants receiving no additional radiotherapy (PET-adapted therapy) versus radiotherapy (standard therapy) (HR 1.86; 95% CI 1.07 to 3.23; P value = 0.03) and in those receiving chemotherapy but no radiotherapy (PET-adapted therapy) versus standard radiotherapy (HR 3.00; 95% CI 1.75 to 5.14; P value < 0.0001) (moderate-quality evidence). Short-term AEs only were assessed in one trial, which showed no evidence of a difference between the treatment arms (RR 0.91; 95% CI 0.54 to 1.53; P value = 0.72) (very-low-quality evidence). No data on long-term AEs were reported in any of the trials. AUTHORS' CONCLUSIONS To date, no robust data on OS, response rate, TRM, QoL, or short- and long-term AEs are available. However, this systematic review found moderate-quality evidence that PFS was shorter in individuals with early-stage HL and a negative PET scan receiving chemotherapy only (PET-adapted therapy) than in those receiving additional radiotherapy (standard therapy). More RCTs with longer follow ups may lead to more precise results for AEs, TRM and QoL, and could evaluate whether this PFS advantage will translate into an overall survival benefit.It is still uncertain whether PET-positive individuals benefit from PET-based treatment adaptation and the effect of such an approach in those with advanced HL.

Waldenström Macroglobulinemia (WM) is a rare B-cell lymphoma characterized by the uncontrolled accumulation of malignant lymphoplasmacytic cells, mainly in the bone marrow, and monoclonal IgM production. Despite its rarity, our understanding of the biology of this disease has improved significantly in recent years with the identification of recurrent mutations in the MYD88 and CXCR4 genes. Based on the diversity of clinical features observed in WM patients, therapy should be highly personalized having into account several factors such as age, co-morbidities, IgM levels, and presence of hyperviscosity, coagulopathy, cryoglobulinemia, or cold agglutinin disease. In this chapter, we review the recent advances in the biology of WM and the current therapeutic options for untreated and relapsed WM patients. Finally, we discuss the role of prognostic factors and current evidence supporting an improvement in the survival of WM patients in the last decade.

Abstract
PURPOSE For classical Hodgkin lymphoma (HL), migrant studies could elucidate contributions of environmental factors (including Epstein-Barr virus (EBV)) to the lower rates in non-whites. Given the well-described etiologic complexity of HL, this research requires a large, immigrant population, such as California Hispanics. METHODS With 1988-2004 California Cancer Registry data (2,595 Hispanic, 8,637 white HL cases) and tumor cell EBV status on a subset (218 Hispanics, 656 whites), we calculated ethnicity- and nativity-specific HL incidence rates simultaneously by age, sex, and histologic subtype, and tumor cell EBV prevalence. RESULTS Compared with white rates, Hispanic HL rates were lower overall (70 %) and for nodular sclerosis HL, particularly among young adults (60-65 % for females). However, they were higher among children (200 %) and older adults, and for mixed cellularity HL. Compared with rates in foreign-born Hispanics, rates in US-born Hispanics were higher among young adults (>threefold in females), lower for children and adults over age 70, and consistently intermediate compared with rates in whites. EBV tumor prevalence was 67, 32, and 23 % among foreign-born Hispanics, US-born Hispanics, and whites, respectively, although with variation by age, sex, and histology. CONCLUSIONS Findings strongly implicate environmental influences, such as nativity-related sociodemographic differences, on HL occurrence. In addition, lower young adult rates and higher EBV prevalence in US-born Hispanics than in whites raise questions about the duration/extent of environmental change for affecting HL rates and also point to ethnic differences in genetic susceptibility. Lesser variation in mixed cellularity HL rates and greater variation in rates for females across groups suggest less modifiable factors interacting with environmental influences.

Different time trends by gender for the incidence of Hodgkin's lymphoma among young adults in the USA: a birth cohort phenomenon. Cancer Causes Control 2014; 25:923-31.

Abstract
OBJECTIVES Hodgkin's lymphoma (HL) is one of the most common cancers among young adults. We investigated the time trends for HL among the 20-44 age group in the USA by gender to identify the potential factors accounting for the incidence trends. METHODS Using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program for 1973-2010, we conducted age-period-cohort modeling to evaluate birth cohort patterns on incidence trends of HL over time. RESULTS For all races combined, the age-adjusted incidence patterns were similar to that of whites. The birth cohort patterns for whites and all races were similar, but the patterns differed according to gender. Specifically, except for the 1970-1975 birth cohort, all other birth cohorts showed an increasing birth cohort trend for females. Conversely, there was a decreasing cohort trend in males beginning in the 1960 birth cohort regardless of the assumptions of the period effect. CONCLUSION The established risk factors for HL can seemingly not explain the gender disparities of the cohort pattern, which necessitates further analytical epidemiological studies to explore the risk factors for this disease with respect to potential differences by gender and by histological subtype.

Abstract
BACKGROUND An increased risk of non-Hodgkin lymphoma (NHL) has been observed among individuals with occupational exposure to benzene, but the risk among those living near benzene release sites has not been well described. METHODS To investigate the spatial patterns of NHL incidence and the association between NHL incidence and distance to benzene release sites, the authors linked and geocoded data on benzene release sites in Georgia from 1988 to 1998 using the Environmental Protection Agency's (EPA) Toxics Release Inventory (TRI), census tract level population statistics, and NHL incidence from the Georgia Comprehensive Cancer Registry (GCCR) from 1999 to 2008. Standardized incidence ratios were mapped by census tract, and a Poisson regression was performed on NHL and NHL subtype incidence data using the mean distance between the tract centroids and release sites as markers of exposure. Cluster analyses were conducted at the global, local, and focal levels. RESULTS Poisson regression indicated that, for every mile the average distance to benzene release sites increased, there was an expected 0.31% decrease in the risk of NHL. Similar results were observed for all NHL subtypes analyzed. Clusters of NHL were spatially associated with benzene release sites located in metropolitan areas, but not with release sites in other areas of the state. CONCLUSIONS NHL incidence was significantly higher in census tracts that were closer, on average, to benzene release sites. Additional studies are needed to examine spatial patterns of NHL incidence in other geographic regions and interactions between benzene and other exposures.

Abstract
BACKGROUND Mantle cell lymphoma (MCL) is a rare B cell lymphoma that varies in clinical behavior with some patients experiencing aggressive disease with short survival, whereas others have indolent behavior. We examined the association between primary disease site and survival in MCL patients to identify subgroups with distinct characteristics. METHODS We analyzed the United States Surveillance, Epidemiology and End Results Program database for MCL cases reported from 2000 through 2009. Kaplan-Meier curves and Cox proportional hazard models were used to estimate the effect of primary site on survival. RESULTS Among 4477 cases included in our study, 19.6% of patients presented with an extranodal primary site. The most common extranodal primary sites were of the gastrointestinal (GI) tract (7.8%), the head and neck (6.2%), and the hematologic/reticuloendothelial systems (3.6%). Asians/Pacific Islanders were more likely than whites or blacks to have GI tract or head and neck disease (P < .0001 and P = .002, respectively). Advanced disease and B symptoms were less common in those with primary disease of the GI tract or head and neck than in those with primary disease of the lymph nodes (both P < .0001). In a multivariate Cox regression model, patients with primary disease of the GI tract and head and neck had superior survival compared to those with primary disease of the lymph nodes; hazard ratios 0.75 (95% CI = 0.62-0.90) and 0.68 (95% CI = 0.55-0.85), respectively. CONCLUSIONS Primary site of disease may be an important prognostic factor for patients with MCL. Further studies elucidating a biological basis for these differences are needed.

Abstract
BACKGROUND Epstein-Barr virus (EBV) is a member of the Herpesviridae family and is associated with Hodgkin lymphoma (HL). Isolates of EBV are classified according to sequence variation in the latency genes such as Epstein-Barr virus nuclear antigen (EBNA). EBNA2 contains the most divergent locus and is classified into type 1 and type 2 or EBNA2A and EBNA2B, respectively. We compared the frequency of EBV and the distribution of EBNA genotypes in Mexican children and adults with HL. PATIENTS AND METHODS Lymph node biopsy specimens from children and adults with HL were embedded in paraffin. EBV was identified by LMP1 amplification and Epstein-Barr-encoded RNA EBER by in situ hybridization (ISH) and genotyped as EBNA2A or EBNA2B using nested polymerase chain reaction (PCR) and specific primers for the detection of subtype. RESULTS Sixty-six samples were obtained from 3 hospitals-42 (63%) from children and 24 (37%) from adults with HL. Thirty-two of the 42 samples (76.1%) were positive for EBV in children and 16 of 24 (66.6%) samples were positive in adults (P = .41). In both children and adults, EBV was found more frequently in male patients. Thirty-four of 48 cases could be typed (70.8%). EBNA2A was found in 7/21 (33.3%) children and in 4/13 (30.8%) adults (P = 1.0), and EBNA2B was found in 10/21 (47.6%) children and in 9/13 (69.2%) adults (P = .22). A mix of subtypes was found in 4/21 (19%) children. CONCLUSION EBV was found frequently in both children and adults with HL. EBNA2B was the most frequent subtype, and a high frequency of mixed subtypes was found in children.

Abstract
Management of Hodgkin's lymphoma continues to develop. Outcomes for patients with favourable-risk, early-stage disease are excellent, and serial reductions in intensity of treatment have been made to retain the excellent prognosis while reducing the late effects of treatment. Prognosis is also very good in advanced-stage disease but the rate of relapse is higher than in early-stage disease, and the optimum first-line treatment is unclear. Workers are investigating the role of functional imaging to assess whether treatment can be tailored according to response, with the most intensive therapies reserved for patients predicted to have poor outcomes. In this Seminar we critically appraise the management of Hodgkin's lymphoma in early-stage disease, advanced-stage disease, and at relapse, with a focus on late effects of treatment.

Abstract
BACKGROUND Racial disparity has been investigated in a number of cancers; however, there remains a comparative paucity of data in Hodgkin's lymphoma (HL). PATIENTS AND METHODS We examined time-, age-, and gender-specific incidence, disease characteristics, and survival across and within races for adolescent/adult HL (age 10-79 years) diagnosed during 1992-2007 in the SEER 13 registries. RESULTS A total of 15 662 HL cases were identified [11,211 non-Hispanic whites, 2067 Hispanics, 1662 blacks, and 722 Asian/Pacific Islanders (A/PI)]. Similar to whites, A/PIs had bimodal age-specific incidence, while blacks and Hispanics did not. Further, HL was significantly more common in Hispanics versus whites age>65 years (7.0/1×10(6) versus 4.5/1×10(6), respectively, P<0.01). By place of birth, US-born Hispanics and A/PIs age 20-39 years had higher incidence of HL versus their foreign-born counterparts (P<0.05), however, rates converged age>40 years. Interestingly, from 1992-1997 to 2003-2007, A/PI incidence rates increased >50% (P<0.001). Moreover, this increase was restricted to US-born A/PI. We also identified a number of disease-related differences based on race. Finally, 5-, 10-, and 15-year overall survival rates were inferior for blacks and Hispanics compared with whites (P<0.005 and P<0.001, respectively) and A/PI (P<0.018 and P<0.001, respectively). These differences persisted on multivariate analysis. CONCLUSION Collectively, we identified multiple racial disparities, including survival, in adolescent/adult HL.

Abstract
BACKGROUND Previous reports suggested that rituximab may impair stem cell collection and posttransplant engraftment in lymphoma patients undergoing autologous hematopoietic progenitor cell transplantation. STUDY DESIGN AND METHODS A prospective biologic allocation study examined the effect of adding rituximab to a mobilization regimen of plerixafor and granulocyte-colony-stimulating factor (G-CSF) for patients with CD20+ lymphoma compared with CD20- lymphoma patients mobilized without rituximab. The primary endpoint was safety of the rituximab-containing regimen; secondary endpoints compared the efficiency of stem cell collection, posttransplant engraftment, graft characteristics, mobilization kinetics, immune reconstitution, and engraftment durability between the cohorts of patients with CD20+ and CD20- lymphoma. RESULTS Fifteen subjects assigned to each treatment arm were accrued. Both mobilization regimens had similar toxicities. The median number of CD34+ cells collected (7.4 × 10(6) /kg vs. 6.4 × 10(6) /kg) and the median numbers of days of apheresis needed to collect stem cells were not different between the CD20+ and CD20- cohorts. No significant differences in neutrophil engraftment (median, 13.5 days vs. 13 days) or platelet engraftment (22 vs. 21 days) or in graft durability were seen comparing patients with CD20+ versus CD20- lymphoma. There were no significant differences in the kinetics of blood T-cell or natural killer-cell reconstitution comparing the two groups. B-cell reconstitution was delayed in the CD20+ lymphoma group, but this did not translate into a significant increase in infectious complications. CONCLUSION Rituximab can be safely added to the combination of plerixafor and G-CSF as a mobilization strategy without excess toxicity or posttransplant engraftment delays for patients with chemosensitive lymphoma undergoing autologous hematopoietic progenitor cell transplantation.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most commonly occurring lymphoma in the Western world. DLBCL is a clinically, biologically, and pathologically heterogeneous entity with biologically distinct subtypes that have different expected treatment outcomes. The addition of rituximab to combination chemotherapy has improved outcomes for all patients with DLBCL and can produce cure for many individuals. Relapsed DLBCL is generally managed with salvage chemo-immunotherapy followed by high dose therapy and autologous stem cell transplantation which can cure additional patients. However, outcomes for patients who relapse early after upfront rituximab and chemotherapy have a poorer prognosis. Novel therapies and strategies are desperately needed for these patients and several emerging treatments hold promise for improving DLBCL treatment outcomes in the future.

Abstract
AbstractAdvanced-stage Hodgkin lymphoma (HL) has become a curable disease in the majority of patients. Research during the last decade has challenged chemotherapy with Adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) as the standard of care and debates continue regarding the role of radiation therapy (RT) in this patient population. The incorporation of interim positron emission tomography (PET) imaging and, recently, further characterization of HL on cellular and molecular levels are emerging as tools for treatment stratification and predictors of disease status. Newer targeted therapies have emerged that are very effective in the relapsed setting and are actively being explored as frontline therapy. Lastly, the expanding population of survivors cured of HL outnumbers patients with the disease and needs to be monitored for therapy-related late effects.

Abstract
Epidemiological studies suggest unique occurrence patterns of Hodgkin lymphoma (HL) worldwide. In most Western countries there is a clear bimodal age distribution with an early peak in young adults followed by a second peak in older adults, particularly among males. In the Middle East and Asia, HL is more common in early childhood. There also are marked racial differences in the presentations of HL and HL subtypes, and particular single nucleotide polymorphisms (SNPs) have been identified as etiological factors suggesting that gene-gene and gene-environment interactions are involved. Personal health choices such as exercise and smoking may modify an individual's chances of developing HL. Numerous studies highlight the impact that exposure to Epstein-Barr virus and other environmental factors have on HL risk. Understanding the relative importance of each of these findings and their links to HL development and survival will help clinical researchers expand curative therapies and create preventative strategies for HL.
