RESUMO

OBJECTIVES: Non-Hodgkin's lymphoma (NHL) risk assessment is crucial in Sjögren's syndrome (SS). We studied the prevalence of clonal immunoglobulin gene rearrangements in minor salivary glands (MSG) and their correlations with lymphoma occurrence and with previously established NHL predictors. METHODS: Molecular B-cell expansion was studied in fresh-frozen MSG of 207 patients with either suspected SS or with suspected lymphoma during SS, using a standardised multiplex PCR assay combined with heteroduplex analysis by microcapillary electrophoresis. The assignation of clonal cases was based on EuroClonality consortium guidelines. RESULTS: Among 207 studied patients, 31 (15%) had MSG monoclonal B-cell infiltration. Monoclonality was significantly more frequent in patients with SS (28/123, 22.8%) compared with patients without SS (3/84, 3.6%, P<0.001). Monoclonal B-cell infiltration in MSG of SS patients correlated significantly with ongoing salivary gland NHL, salivary gland swelling, CD4+ T-cell lymphopenia, rheumatoid factor (RF) activity, low complement levels and type 2 mixed cryoglobulinemia. The accumulation of biological risk factors was associated with a higher rate of MSG B-cell monoclonality given that patients with only positive RF had no probability of MSG B-cell monoclonality, RF-positive patients with 1 or 2 other risk factors had a 25.0% and 85.7% probability of MSG B-cell monoclonality, respectively. CONCLUSION: The detection of MSG monoclonal B-cell expansion by this easy-to-perform molecular assay is useful, both at the time of diagnosis and during the course of SS. Monoclonal B-cell expansion is associated with a subset of SS patients presenting either ongoing lymphoma or other established lymphoma predictive factors.

RESUMO

Recent literature suggests a combination of flow cytometric determination of Ki-67 and immunophenotype as a reliable tool to classify canine lymphomas. Immunohistochemistry (IHC) on histological samples is the gold standard technique assessing Ki-67 index. Agreement between IHC and FCM derived Ki-67 indices has never been investigated. The aim of this study was to investigate the agreement between IHC and FCM in the assessment of Ki-67 expression/index, in order to evaluate whether FCM may serve as a non-invasive alternative method for the estimation of proliferative activity in canine lymphoma. Dogs with previously untreated canine lymphoma undergoing diagnostic lymphadenectomy were prospectively enrolled. Ki-67 expression/index was assessed by FCM and IHC and expressed as percentage of positive cells. 39 dogs classified by histopathology matched the inclusion criteria. With both methods, Ki-67 expression/index was higher in intermediate/high-grade lymphomas. Spearman's coefficient of correlation was ρ = 0.57; (95% CI0.33-0.75) suggesting a moderate correlation. A Bland-Altman plot revealed a negative constant bias of -3.55 (95% CI: -10.52 to 3.42) with limits of agreement from -45.71 to 38.61. The study confirmed agreement albeit with wide confidence intervals between the values of Ki-67 expression/index assessed with FCM and IHC. Discrepancies were observed in a subset of cases. Possible explanation could be that Ki-67 index in IHC is determined in the most proliferative areas of the slide, which could introduce kind of sampling bias, whereas FCM evaluates many more cells in cell suspension. Further studies are warranted to investigate this phenomenon.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the incidence and risk of non-Hodgkin's lymphoma (NHL) and thyroid cancer in patients with primary Sjögren's syndrome (pSS) using the Korean National Health Insurance Service (NHIS) claims database. METHODS: pSS was identified using the Korean NHIS medical claims database between 2007 and 2017. The case definition required more than one visit based on the SS diagnostic code and the registration system for rare and incurable diseases. We included all admissions with a primary diagnosis of lymphoma and thyroid cancer. RESULTS: The pSS incidence was 1.88 cases/100,000 inhabitants. Female patients had a higher incidence than male patients, with a female-to-male ratio of 7.65:1. Of those, we identified 18 (0.34%), 1 (0.02%) and 29 (0.56%) patients with NHL, Hodgkin's disease and thyroid cancer, respectively. For pSS, the standardised incidence ratios for NHL and thyroid cancer were 6.32 (95% confidence interval [CI] 4.09-9.38) and 1.23 (95% CI 0.88-1.68), respectively. Compared with the general population, female patients with pSS had a 6.95-fold higher risk of developing NHL, while the male patients did not. Patients with pSS did not have a higher risk of developing thyroid cancer. CONCLUSIONS: Although pSS is associated with a higher risk of developing NHL, the risk of NHL appears to have decreased compared with that in previous studies. Our study suggests that the risk of NHL or thyroid cancer with SS is not higher than that reported in previous studies.

RESUMO

There is limited information on the cost burden associated with follicular lymphoma (FL) and how it compares to other non-Hodgkin lymphoma (NHL) subtypes. We examined the direct medical costs associated with FL and estimated the incremental 3-year cost of FL compared to other NHL subtypes. Using the linked Surveillance, Epidemiology and End Results-Medicare dataset, we identified 16,691 NHL patients aged 66 years or older who were diagnosed with NHL between 2007 and 2013. The mean 3-year cost among the full NHL sample was $120,120 (standard error (SE) 839). The mean 3-year cost per patient was $114,443 (SE 1738) for FL and $121,402 (SE 950) for non-FL subtypes. The incremental 3-year cost of FL compared to non-FL was US$-5458 (95% confidence interval: US$-9325 to US$-1590). Longitudinally, FL was less costly than other NHL subtypes in the first year only, and became more expensive in the second and third years.

RESUMO

BACKGROUND: Chemotherapy regimens historically have required admission of the patient to the hospital for extended infusions running over multiple days to complete each cycle of therapy. With the evolution of monitoring strategies readily available, a renaissance in patient care and healthcare cost utilization is necessary as transitioning the administration of these agents to the outpatient setting is seemingly achievable and is potentially more cost-effective. PURPOSE: This evaluation sought to primarily measure cost-savings for an institution by transitioning inpatient chemotherapy regimens to the outpatient setting. Secondary outcomes evaluated the effect of this transition on overall patient length of stay, prevalence of adverse effects, and overall chemotherapy schedule adherence as a result of implementing transitions in sites of care. Barriers to receiving care in the outpatient setting were assessed by evaluating the acuity of performance status as well as distance from the hospital. METHODS: This single-center retrospective, quantitative chart and expense analysis evaluated patients receiving rituximab, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (R-EPOCH) or rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) chemotherapy regimens based on treatment setting at a single institution. Included patients were treated at the University of Chicago Medical Center. Those receiving inpatient-only management as compared with patients who received therapy in outpatient settings were compared in a matched cohort analysis. The control group was matched from the period before transition of therapy was instituted between November 2014 and November 2015, with those patients transitioned to outpatient therapy (December 2015 to November 2016), using demographic, diagnostic, treatment, and clinical status data to assure group similarity. Mean cost of therapy was compared between inpatient and outpatient regimens. Descriptive and demographic categorical data were compared using the Fisher's exact test. Continuous data were evaluated using the Student's t test. A significance level of alpha <0.05 was used for all analysis. RESULTS: The cost of R-EPOCH therapy represented a significant difference across groups. R-ICE therapy similarly saw significant cost differences between inpatient and outpatient groups. If this was made standard of care for qualifying patients a retrospective annualized estimation of $466,507.85 with R-EPOCH therapy and $205,977.60 for R-ICE therapy could have been saved if this was utilized for patients who previously received their therapy as an inpatient. CONCLUSION: The population of patients cared for at the University of Chicago Medicine during this time-period qualified for outpatient treatment for those treated with R-EPOCH and R-ICE regimens with no significantly identifiable prohibitive barriers between groups. As no significant complications manifested, it is reasonable to continue transitioning patients receiving these regimens to the outpatient setting where appropriate. R-EPOCH and R-ICE therapies were shown to be reasonable outpatient therapy while providing significant cost-savings for the institution.

RESUMO

Adoptive cellular immunotherapy with anti CD19 chimeric antigen receptor (CAR)-T cell has changed the treatment landscape in relapsed/refractory B cell lymphomas. They have emerged as effective therapy in patients with multiple relapsed/refractory disease, capable of sustaining durable remissions. Two CAR-T cell products (axicabtagene ciloleucel and tisagenlecleucel) are currently approved by the United States Food and Drug Administration. A third anti CD19 CAR-T cell, lisocabtagene ciloleucel is currently being evaluated in large clinical trials and may also be United States Food and Drug Administration-approved soon. CAR-T cell-related toxicities, including infections, cytokine release syndrome, and neurotoxicity are potential complications of therapy. With increasing use of CAR-T cells, the mechanism of toxicities and mitigation strategies needs to be developed. Additionally, reasons for CAR-T cell failure and progression following this therapy needs to be further studied. We describe the recent developments in this field, with emphasis on the complications of therapy and factors contributing to toxicities, efficacy, and resistance. We also describe the ongoing research in this field and the newer CAR-T cell constructs that are being developed to counter the challenges that have been identified in this field.

RESUMO

Background: Multiparameter flow cytometry is a useful tool for diagnostic evaluation of mature B-cell neoplasms (MBN). Recently, it has been shown that assessment of CD200 expression may improve the distinction between chronic lymphocytic leukemia (CLL; CD200 positive) and mantle cell lymphoma (MCL; CD200 negative), but any potential as a prognostic marker for CLL remains to be established. Materials and methods: This cross sectional study was conducted on sixty-seven patients newly diagnosed as having mature B-cell lymphoproliferative disorders Levels of CD 200 in lymphoma cells were assessed. Results: CD200 was consistently expressed in CLL and hairy cell leukemia B cells, but not in MCL cells. Heterogeneous expression was noted in other CD5 positive Non-Hodgkin lymphomas. High CD200 expression (≥50%) was associated with a higher CD5, 19 and CD23 expression, older age, higher TLC and absolute lymphocyte count, hepatomegaly, splenomegaly and a higher Rai stage. There were no significant correlations between CD200 expression and response to treatment. Conclusion: CD200 could be of high value in distinguishing CLL, MCL, and atypical CLL. CD200 expression can also be of prognostic and therapeutic value in CLL cases.

RESUMO

Atrial fibrillation (AF) and cancer are common disorders in the general population but there are few studies in patients with both diseases. More specifically, there are scarce data on AF in patients with non-Hodgkin lymphoma (NHL). We assessed the incidence, predictive factors, management, and survival impact of AF in a cohort of patients with NHL from a single institution between 2002 and 2016 (n = 747). Twenty-three patients were diagnosed with AF before and 40 after the diagnosis of NHL (of the later, 16 were secondary to an extracardiac comorbidity and 24 unrelated to any triggering event [primary AF]). The 5-year cumulative incidence of new-onset AF was 4% (95% confidence interval [CI] 3-6%). Age and hypertension were the only predictive factors for the development of AF. Management of AF was heterogeneous, primarily with anti-vitamin K agents but also antiplatelet therapy in a significant proportion of patients. Among the 63 patients, there were six episodes of ischemic stroke/transient ischemic attack and four venous thromboembolic events, with four major bleeding episodes. Overall survival (OS) was inferior in patients with AF (HR 0.1, 95% CI 0.01-0.7, p = 0.02), largely due to secondary AF. We conclude that the incidence of new-onset AF in NHL patients seemed somewhat higher than in the general population, although with similar predictive factors. The management was heterogeneous, and the risk of ischemic and hemorrhagic events did not seem higher than in cancer-free patients. Survival was particularly poor for patients with secondary AF.

RESUMO

Interpretation of endpoints (e.g. overall response rate) in clinical trials depends on the accurate and reliable measurement and identification of tumors. Regulatory agencies recommend blinded reviews of imaging data by independent review committees (IRCs). Differences in response outcomes that arise between IRCs and site investigators raise regulatory/sponsor concerns. Here, we evaluate discrepant tumor response assessments by the IRC and unblinded investigators (complete versus partial response, respectively) occurring in 52 (13% of 393 IRC-assessed responders) of 447 enrolled patients with treatment-naïve non-Hodgkin lymphoma from a randomized study. The IRC and investigators were 'likely correct' in 73% and 25% of cases, respectively (p < .001). Investigators were more likely to make errors by misinterpreting lymph node data and not utilizing PET results. This post hoc finding suggests a possible role for post-training site evaluation/audit, with retraining as needed, and a specialized consensus committee for concurrent blinded review of site/central data.

RESUMO

In recent years, the Comprehensive Geriatric Assessment (CGA), which is used in gerontology to assess functioning in elderly individuals, has been said to be useful in geriatric oncology. Therefore, we examined whether items in the CGA were associated with survival time in elderly patients with non-Hodgkin lymphoma (NHL). We conducted the CGA for 93 patients aged ≥ 65 years who had undergone treatment for NHL retrospectively. The CGA includes activities of daily living, instrumental activities of daily living, mood, cognition, nutrition, and the Charlson comorbidity index. For each category, we divided subjects into a "good" group and a "poor" group. In regard to the Charlson comorbidity index, patients were divided into two groups using different cutoffs to divide the groups; the two groups were established according to the division with the largest significant difference in survival time. Multivariate analysis was then performed with the following prognostic factors affecting survival: all CGA items, NHL classification, stage, performance status, and doxorubicin use/non-use. We also performed similar analysis for 43 diffuse large B-cell lymphoma (DLBCL) patients who had undergone anthracycline treatment. Results are factors affecting survival in NHL cases included comorbidity score ≥ 6 (P < 0.0001), doxorubicin non-use (P = 0.005), and cognitive impairment (P = 0.0488). In cases of DLBCL, survival was affected by comorbidity score ≥ 5 (P = 0.0016). High comorbidity score was strongly associated with survival in both NHL and DLBCL.

RESUMO

Great advances have been made in the treatment of paediatric non-Hodgkin lymphoma (NHL). In high-income countries (HIC), cure rates now exceed 85%. However, in low- and middle-income countries (LMIC), cure rates remain less than 50%. It is estimated that over 90% of paediatric NHL worldwide occur in LMIC; therefore, even modest improvements in outcome would have significant impact in reducing the burden of paediatric NHL globally. This article will discuss some of the issues required to improve the outcome of paediatric NHL in LMIC using data presented at the Fifth International Symposium on Childhood, Adolescent and Young Adult Non-Hodgkin Lymphoma held in Varese, Italy, 2015 to illustrate these issues. Additionally, potential bi-directional benefits for patients in both LMIC and HIC from future collaborations will be discussed.

RESUMO

INTRODUCTION: This study prospectively evaluated whole-body magnetic resonance/diffusion-weighted imaging with body signal suppression (WB-MR/DWIBS) reliability compared to (18)F-FDG PET/CT in the treatment response assessment of classic Hodgkin lymphomas (HL) and aggressive non-Hodgkin lymphomas (aNHL). MATERIALS AND METHODS: Twenty-seven consecutive patients were prospectively enrolled at the time of diagnosis. Eighteen (11 HL and seven aNHL) were considered for the analysis. They received chemo/radiotherapy as induction and completed post-treatment evaluation performing both (18)F-FDG PET/CT and WB-MR/DWIBS. The revised response criteria for malignant lymphomas were used to assess the response to treatment. We evaluated the agreement between the two methods by Cohen's K test. Post-therapy WB-MR/DWIBS sensitivity, specificity, PPV, NPV and accuracy were then calculated, considering the 12 months of follow-up period as the gold standard. RESULTS: By using an evaluation on a lesion-by-lesion basis, WB-MR/DWIBS and (18)F-FDG PET/CT showed an overall good agreement (K = 0.796, 95% IC = 0.651-0.941), especially in the evaluation of the nodal basins in aNHL (K = 0.937, 95% IC = 0.814-1). In reference to the revised response criteria for malignant lymphomas, the two methods showed a good agreement (K = 0.824, 95% IC = 0.493-1). Post-therapy sensitivity, specificity, PPV, NPV and accuracy of WB-MR/DWIBS were 43, 91, 75, 71 and 72%, respectively. CONCLUSION: WB-MR/DWIBS seems to be an appropriate method for the post-treatment assessment of patients affected by HL and aNHL. The small discrepancies between the two methods found within HL could be due to the biological and metabolic behavior of this group of diseases. Larger prospective studies are necessary to better define the role of WB-MR/DWIBS in this setting of patients.

RESUMO

PURPOSE: Previous studies have reported that survivors of non-Hodgkin lymphoma (NHL) have an increased risk of developing cutaneous melanoma; however, risks associated with specific treatments and immune-related risk factors have not been quantified. PATIENTS AND METHODS: We evaluated second melanoma risk among 44,870 1-year survivors of first primary NHL diagnosed at age 66 to 83 years from 1992 to 2009 and included in the Surveillance, Epidemiology, and End Results-Medicare database. Information on NHL treatments, autoimmune diseases, and infections was derived from Medicare claims. RESULTS: A total of 202 second melanoma cases occurred among survivors of NHL, including 91 after chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and 111 after other NHL subtypes (cumulative incidence by age 85 years: CLL/SLL, 1.37%; other NHL subtypes, 0.78%). Melanoma risk after CLL/SLL was significantly increased among patients who received infused fludarabine-containing chemotherapy with or without rituximab (n=18: hazard ratio [HR], 1.92; 95% CI, 1.09 to 3.40; n=10: HR, 2.92; 95% CI, 1.42 to 6.01, respectively). Significantly elevated risks also were associated with T-cell activating autoimmune diseases diagnosed before CLL/SLL (n=36: HR, 2.27; 95% CI, 1.34 to 3.84) or after CLL/SLL (n=49: HR, 2.92; 95% CI, 1.66 to 5.12). In contrast, among patients with other NHL subtypes, melanoma risk was not associated with specific treatments or with T-cell/B-cell immune conditions. Generally, infections were not associated with melanoma risk, except for urinary tract infections (CLL/SLL), localized scleroderma, pneumonia, and gastrohepatic infections (other NHLs). CONCLUSION: Our findings suggest immune perturbation may contribute to the development of melanoma after CLL/SLL. Increased vigilance is warranted among survivors of NHL to maximize opportunities for early detection of melanoma.

RESUMO

BACKGROUND: In the UK, approximately five people are diagnosed with Hodgkin lymphoma (HL) daily. One-tenth of diagnoses are in those aged >75 years. AIM: To establish a symptom profile of HL and quantify their risk in primary care patients aged ≥40 years. DESIGN AND SETTING: Matched case-control study using Clinical Practice Research Datalink patient records. METHOD: Putative clinical features of HL were identified in the year before diagnosis. Results were analysed using conditional logistic regression and positive predictive values (PPVs) calculated for the consulting population. RESULTS: Two-hundred and eighty-three patients aged ≥40 years, diagnosed with HL between 2000 and 2009, and 1237 age, sex, and general practice-matched participants were studied. Six features were independently associated with HL: lymphadenopathy (OR 280, 95% confidence interval [CI] = 25 to 3100), head and neck mass not described as lymphadenopathy (OR 260, 95% CI = 21 to 3200), other mass (OR 12, 95% CI = 4.4 to 35), thrombocytosis (OR 6.0, 95% CI = 2.6 to 14), raised inflammatory markers (OR 5.2, 95% CI = 3.0 to 9.0), and low full blood count (OR 2.8, 95% CI = 1.6 to 4.8). Lymphadenopathy per se has a positive predictive value (PPV) of 5.6% for HL in patients aged ≥60 years. CONCLUSION: Consistent with secondary care findings, lymphadenopathy is the clinical feature with the highest risk of HL in primary care and warrants urgent investigation.

RESUMO

Non-Hodgkin lymphoma (NHL) represents a heterogeneous group of diseases that are known to carry a considerable risk of second primary cancer (SPC). However, little attention has been paid to SPC risk assessment according to NHL subtypes. Data from 10 French population-based cancer registries were used to establish a cohort of 7546 patients with a first diagnosis of NHL (eight subtypes) between 1989 and 2004. Standardized incidence ratios (SIRs) of metachronous SPC were estimated. Among the 7546 patients diagnosed with a NHL, the overall SPC risk was 25% higher than that in the reference population (SIR = 1.25, 95% confidence interval 1.15-1.36). In univariate analysis, the SPC risk differed by lymphoma subtype. Interestingly, multivariate analysis showed that SPC risk did not differ significantly across NHL subtypes after adjustment for the other covariates (p = 0.786). Patients with NHL have an increased risk of SPC that is not influenced by the histological NHL subtype.

RESUMO

The age-adjusted International Prognostic Index (IPI) is an important prognostic factor for patients with non-Hodgkin lymphoma (NHL). We investigated whether a geriatric assessment (GA) is of additional prognostic value in NHL. In this prospective cohort study of 44 patients aged 70 years or older with NHL receiving rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), a GA was administered before the start of chemotherapy. GA was composed of the Mini Nutritional Assessment (MNA), Groningen Frailty Indicator (GFI), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Mini Mental State Examination (MMSE) and levels of albumin, creatinine, lactate dehydrogenase (LDH) and hemoglobin. Multivariate analyses were performed using logistic regression and the Cox regression model. After adjustment for sex, age, comorbidity and univariate laboratory values with p ≤ 0.1, abnormal MNA and GFI scores and low hemoglobin level were associated with not being able to complete the intended chemotherapy: odds ratio (OR) 8.29 (95% confidence interval [CI]: 1.24-55.6; p = 0.03), 9.17 (95% CI: 1.51-55.8; p = 0.02) and 5.41 (95% CI: 0.99-29.8; p = 0.05), respectively. Adjusted for sex, age, comorbidity, age-adjusted IPI and univariate laboratory values with p ≤ 0.1, frailty by GFI and low hemoglobin were associated with worse survival, with a hazard ratio (HR) of mortality of 2.55 (95% CI: 1.07-6.10; p = 0.04) and 4.90 (95% CI: 1.76-13.7; p = 0.002), respectively. We conclude that (risk of) malnutrition, measured with the MNA, frailty, measured with the GFI, and low hemoglobin level had additional predictive value for early treatment withdrawal, and GFI and hemoglobin were, independent of the age-adjusted IPI, predictive for an increased mortality risk.
