    2016-01-01

    Radiation therapy (RT) alone has been considered for a long time as the standard therapeutic option for limited stage FL, due to its high efficacy in terms of local disease control with a quite significant proportion of ?cured? patients (without further relapses at 10?15 years). Multiple therapeutic choices are currently accepted for the management of early stage FL at diagnosis, and better staging procedures as well as better systemic therapy partially modified the role of RT in this setting...

    Less than 20% of patients with follicular lymphoma (FL) present with Ann Arbor Stage I or II disease at diagnosis. Numerous therapeutic options exist, however radiation therapy is considered the standard of care for early-stage disease based on single-institution or retrospective series. Our aim was to revisit the outcome of patients with localized FL in the rituximab era. We analyzed the characteristics and outcomes of 145 early-stage FL patients, who were retrospectively divided into six groups according to their initial treatment: watchful waiting (WW), chemotherapy alone (CT), radiotherapy alone (RT), combined radiotherapy and chemotherapy (RT-CT), rituximab alone (Ri), and immunochemotherapy (Ri-CT). Of the 145 patients, 84 (57.9%) had stage I disease and 61 (42.1%) stage II. The complete response (CR) rate varied from 57% for the Ri group to 95% for the RT-CT group. Overall survival (OS) at 7.5 y of patients treated after 2000 was better than that of those treated prior to 2000. OS did not significantly differ from one treatment to another. In contrast, a significant difference was found for progression-free survival (PFS) at 7.5 y, which favored Ri-CT (60%) therapy versus the others (p=0.00135). Delayed therapy initiation was associated with a similar OS than that observed in patients receiving immediate intervention. The "watchful waiting" strategy may thus be proposed as first-line therapy, similar to stage III and IV FL patients with a low tumor burden. However, when treatment is required, immunochemotherapy appears to be the best option.

    The case is presented of a 43 year-old male patient with chronic follicular conjunctivitis, negative bacterial serology, and refractory to local treatment. The incisional biopsy performed showed to be consistent with reactive lymphoid hyperplasia. A year later, a new incisional biopsy showed follicular lymphoma, with no systemic involvement, and he was treated with local radiotherapy. When a chronic follicular conjunctivitis is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis that can range from chronic inflammation, reactive lymphoid hyperplasia to lymphoma. Follicular lymphoma is rare among conjunctival lymphomas, and the staging is indispensable for the correct therapeutic approach. Copyright © 2014 Sociedad Española de Oftalmología.

    Background: in patients with advanced-stage III/IV follicular lymphoma (FL), there are many treatment options available. The current challenge is to choose the optimal strategy for the individual patient. Methods: the literature was reviewed with respect to treatment strategies in patients with advanced FL by screening the PubMed databank. Results: in advanced-stage III/IV FL, median survival may approach 8-10 years. Treatment strategies include a watch-and-wait strategy, chemoimmunotherapy, monotherapy with rituximab, and - as an experimental approach so far - radioimmunotherapy. The use of autologous hematopoietic stem cell transplantation (HSCT) for patients in first remission or chemosensitive relapse prolongs progression-free survival while the effect on overall survival remains unclear compared to standard chemotherapy. However, long-term results are flawed by high relapse rates and risk of secondary malignancies. In patients with relapsed/chemoresistant disease, allogeneic HSCT constitutes the only curative approach but is associated with high treatment-related mortality. In the palliative setting, low-dose involved-field irradiation constitutes an effective treatment option in order to control local symptoms with potential long-lasting response. Conclusion: in case of advanced-disease FL, asymptomatic patients can be managed expectantly. In symptomatic patients, chemoimmunotherapy is regarded as standard therapy. In symptomatic elderly patients with relevant comorbidities, rituximab {+-} single-agent chemotherapy, or low-dose involved-field radiotherapy might be appropriate. For younger patients with chemoresistant/relapsed disease, allogeneic HSCT might be considered, since advances in supportive care and better patient selection have resulted in improved outcomes.

    Purine analogs have demonstrated significant activity in patients with follicular lymphoma. The aim of this study was to analyze the efficacy and toxicity of a fludarabine combination as first-line treatment in patients with advanced-stage disease. This is a phase II trial including 120 patients ( or =2), > or =2 extranodal sites and high beta2-microglobulin. Sixteen episodes of grade 3-4 infections were observed. Two patients died during therapy (of progressive multifocal leukoencephalopathy and bronchoaspiration respectively). No late toxicity has been observed. Twelve patients died during follow-up (9 after relapse, 2 during chemotherapy, 1 in complete remission after surgery for meningioma). The overall survival at 5 years was 89%. ECOG > or =2 and high beta2-microglobulin were associated with a shorter survival. FCM results in high complete and molecular response rates, with prolonged response duration in younger patients with advanced-stage follicular lymphoma. The combination of FCM with rituximab as front-line treatment warrants further investigation.

    Follicular lymphoma (FL) is the most common indolent non-hodgkin lymphoma. Most patients with FL are diagnosed with advanced disease and are considered incurable. The classical prognostic index in FL is the FL international prognostic index (FLIPI). The management of FL is mainly determined by histologic grading, clinical stage, and tumor burden. For patients with stage I and II disease, an involved-site radiation therapy (ISRT) is recommended and may be potentially curative approach with 60% to 80% of 10-year overall survival (OS) rates, while patients with stage III and IV should be treated with systemic therapy. The watchful waiting is still an option for patients without symptoms or/and low tumor burden. Induction of immuno-chemotherapy combined with consolidation of rituximab maintenance (MR) is standard care for patients with symptomatic disease or with high tumor burden when treatment indicated. The major indication for systemic therapy is including candidate for clinical trials, threatened end organ function, cytopenia secondary to lymphoma bulky disease and steady progress etc. at present time. Routine baseline and regular hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (HBcAb) testing is strongly recommended for all patients before the initiation of immuno-chemotherapy in order to minimize the risk of hepatitis B virus (HBV) reactivation which has been observed approximately 20% to 50% of patients with positive HBsAg and 3% to 45% of patients with positive HBcAb. Prophylactic antiviral treatment in patients who are HBsAg-positive or HBcAb-positive is indicated before immuno-chemotherapy. The management for elderly patients should be carefully selected to avoid overtreatment and severe toxicities. Individualized dose adjustment for chemotherapy and an adequate supportive treatment are essential for this special population. Novel agents such as lenalidomide, ibrutinib and idelalisib are promising. In conclusion, individualized management

    This paper presents a summary of the evidence review group (ERG) report into the clinical and cost-effectiveness of rituximab for the first-line treatment of stage III/IV follicular non-Hodgkin's lymphoma (FNHL) based upon the manufacturer's submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal (STA) process. The manufacturer's scope restricts the intervention to rituximab in combination with CVP (cyclophosphamide, vincristine and prednisolone) (R-CVP); the only comparator used was CVP alone. The evidence from the one included randomised controlled trial (RCT) suggests that the addition of rituximab to a CVP chemotherapy regimen has a positive effect on the outcomes of time to treatment failure, disease progression, overall tumour response, duration of response and time to new lymphoma treatment in patients with stage III/IV FNHL compared with CVP alone. Adverse events were comparable between the two arms. This study was confirmed as the only relevant RCT. The economic analyses provided by the manufacturer were modelled using a three-state Markov model with with the health states being defined as progression-free survival (PFS), progressed (in which patients have relapsed) and death (which is an absorbing state). The model generated results for a cohort of patients with an initial age of 53 and makes no distinction between men and women. The model is basic in design, with several serious design flaws and key parameter values that are probably incompatible. Attempting to rectify the identified errors and limitations of the model did not increase the incremental cost-effectiveness ratio (ICER) above 30,000 pounds. Although the cost-effectiveness results obtained appear to be compelling in support of R-CVP compared with CVP for the trial population the results may not be so convincing for a more representative population. The results of the ERG analysis on the impact of age suggest that ICERs increase

    The goal of this work was to analyze the response rate and outcome of patients with stage I-III follicular lymphoma (FL) treated with radiotherapy (RT) alone. The records of 50 consecutive patients with stage I-III FL treated with RT alone at our department from 1988-2009 were analyzed. The median age was 60 years (range 32-80 years) with a median follow-up duration of 8 years (range 4-11 years). Clinical staging was performed according to the Ann Arbor system. Stage I: 30 patients (60%), stage II: 15 patients (30%), stage III: 5 patients (10%). Thirty-two patients (64%) presented with nodal disease, 14 patients (28%) presented with disease in extranodal sites, and 4 patients (8%) had nodal and extranodal involvement. The RT field encompassed only the involved Ann Arbor nodal regions (involved-field RT) in 26 patients (52%), mantle and whole abdominopelvic fields in 6 patients (12%), mantle field in 10 patients (20%), whole abdominopelvic fields in 5 patients (10%), and a so-called mini-mantle in 3 patients (6%). The total RT dose ranged from 26-56 Gy (median 40 Gy) in daily fractions of 1.2-2.5 Gy. Complete remission (CR) and partial remission (PR) were observed in 39 (76%) and 9 (20%) patients, respectively. Only 2 of 8 patients (25%) with tumor bulk > 5 cm reached CR, whereas 37 of 42 patients (88%) with a maximum lymphoma diameter < 5 cm achieved CR (p = 0.0001). The median overall survival (OS) and median event-free survival (EFS) were 18 years (CI 95% 10-26 years) and 7 years (6-8 years), respectively. The 2-, 5-, and 10-year OS were 96 {+-} 3%, 90 {+-} 5%, and 70 {+-} 9%, respectively. The 2-, 5-, and 10-year EFS were 90 {+-} 5%, 70 {+-} 7%, and 38 {+-} 9%, respectively. Fifteen patients developed a recurrence outside the radiation field (30%) and 4 patients developed an in-field recurrence (8%). All in-field recurrences were observed in regions without clinical (macroscopic) involvement, which were irradiated with a dose of {<=} 26 Gy. Pretreatment maximum

    Local (involved-field or recently involved-site) radiotherapy is the standard therapy in limited-stage follicular lymphoma (FL). We retrospectively analyzed the value of chemotherapy in 130 patients with limited-stage FL (46 treated with radiotherapy alone [RT group], 30 with radiotherapy plus chemotherapy [COMBINED group] and 43 with chemotherapy alone [CHEMO group], 11 were managed with observation). Ninety-six percent of patients responded (RT 98%, COMBINED 100%, CHEMO 91%, p=0.179), and 37% (40/107) of patients in complete response relapsed (RT 42%, COMBINED 27%, CHEMO 41%, p=0.371). Progression-free survival (PFS) and overall survival (OS) probabilities at 10 years were similar in RT, COMBINED and CHEMO patients (PFS 41%, 61% and 39% [p=0.167], and OS 77%, 81% and 72% [p=0.821], respectively), while the COMBINED group showed a trend to better time-to-progression (TTP 43%, 72% and 47% [p=0.055]). On multivariate analysis, only a FLIPI score ≥2 showed a trend to influence PFS (HR 2.1 [95% confidence interval 0.9-4.6], p=0.067), and OS (HR 2.4 [0.9-6.5], p=0.084), while patients treated with radiotherapy plus chemotherapy (COMBINED group) showed a significantly better TTP compared with those receiving only RT (HR 0.3 [0.1-0.8], p=0.024). In our study no benefit was observed in survival with the use of systemic therapy compared with local radiotherapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Follicular lymphoma (FL is an indolent disease, but 30%–40% of cases undergo histologic transformation to an aggressive malignancy, typically represented by diffuse large B cell lymphoma (DLBCL. The pathogenesis of this process remains largely unknown. Using whole-exome sequencing and copy-number analysis, we show here that the dominant clone of FL and transformed FL (tFL arise by divergent evolution from a common mutated precursor through the acquisition of distinct genetic events. Mutations in epigenetic modifiers and antiapoptotic genes are introduced early in the common precursor, whereas tFL is specifically associated with alterations deregulating cell-cycle progression and DNA damage responses (CDKN2A/B, MYC, and TP53 as well as aberrant somatic hypermutation. The genomic profile of tFL shares similarities with that of germinal center B cell-type de novo DLBCL but also displays unique combinations of altered genes with diagnostic and therapeutic implications.

    Non-Hodgkin Lymphomas (NHL) represent a recent and fascinating domain of hemato-oncology, in which remarkable progress has been made. The conventional treatments of indolent lymphomas do not extend the survival rate, nor do they cure. Recent directions are centered on using several new drugs that are capable of overcoming the mechanisms that are resistant to recovery. The initiation of immunotherapy (Rituximab in 1997) seems to have changed the natural evolution of follicular lymphomas (FL). It is possible that resistance to healing in follicular lymphomas may be neutralized with Rituximab by suppressing STAT-1 positive macrophages that are present in the cellular microenvironment.Thereinafter, the re-evaluation of recent models of prognostic and therapeutic paradigmas that were used in FL became compulsory.The purpose of the paper is to compare the evolution of patients with follicular lymphoma and the period of response, according to the treatments. The study group consisted of the 71 patients diagnosed with follicular lymphoma, out of a total of 767 malignant lymphatic proliferations with B cells, for a period of 7 years (2002-2008), at the Hematology Department, Hospital Coltea, Bucharest and Hematology Department, Universitary Hospital, BucharestResults and conclusions: Combining chemotherapy with Rituximab had better results compared to the same chemotherapy, administered alone, both in induction and in case of relapse. The overall response rate in our study group was 74.7%, out of which 42.3% complete remissions. The overall response rate was 84.61% in the Rituximab group, compared to 68.88% in patients without Rituximab.

    Purpose: Rituximab (Rit) therapy added to involved-field radiation therapy (RT) has been proposed as an effective treatment for stage I-II follicular lymphoma (FL). The results of an observational multicenter study on the Rit-RT combination in limited-stage FL are here reported. Methods and Materials: Data have been collected from 2 consecutive cohorts of 94 patients with stage I-II FL treated between 1985 and 2011 at 5 Italian institutions. All patients had grade 1-3a FL, a median age of 54 years (range: 25-82). The first 51 patients received RT alone (control group), while the subsequent series of 43 patients received 4 rituximab courses (375 mg/m{sup 2}, days 1, 8, 15, 22) before RT (Rit-RT). Molecular disease was evaluated by nested bcl-2/IgH PCR or clonal IgH rearrangement was available in 33 Rit-RT patients. Results: At a median follow-up of 10.9 years (range: 1.8-22.9), the 10-year progression-free survival (PFS) and overall survival (OS) projections for the whole cohort were 57% and 87.5%, respectively. The 10-year PFS was significantly longer (P<.05) in the Rit-RT group (64.6%) compared to RT alone (50.7%), whereas the 10-year OS projections were not significantly different. On bivariate analysis controlling for stage, there was only a trend toward improved PFS for Rit-RT (HR, 0.55; P=.081). Follicular lymphoma international prognostic index and age were associated with OS but not with PFS on Cox regression analysis. Bone marrow molecular analysis showing PCR positivity at diagnosis was strongly associated with relapse risk upon univariate and multivariate analysis. Conclusions: This multicenter observational study suggests a potential benefit of adding rituximab to radiation therapy for stage I-II FL. The results of the currently ongoing randomized studies are required to confirm these results. The study underlines the importance of molecular disease monitoring also for patient with limited-stage disease.

    Follicular lymphoma is generally an indolent B cell lymphoproliferative disorder of transformed follicular center B cells. Follicular lymphoma (FL) is characterized by diffuse lymphoadenopathy, bone marrow involvement, splenomegaly, and less commonly other extranodal sites of involvement. In general cytopenias can occur but constitutional symptoms of fever, nightsweats, and weight loss are uncommon. Diagnosis is based on histology of preferably a biopsy of a lymph node. Immunohistochemical staining is positive in virtually all cases for cell surface CD19, CD20, CD10, and monoclonal immunoglobulin, as well as cytoplasmic expression of bcl-2 protein. The overwhelming majority of cases have the characteristic t(14;18) translocation involving the IgH/bcl-2 genes. The Follicular Lymphoma International Prognostic Index prognostic model for FL uses five independent predictors of inferior survival: age >60 years, hemoglobin  normal, Ann Arbor stage III/IV, number of involved nodal areas > 4. The presence of 0, 1, 2, and  ≥ 3 adverse factors defines low, intermediate, and high-risk disease. With the use of more modern therapies, outcomes have improved. Observation continues to be adequate for asymptomatic patients with low bulk disease and no cytopenias. For patients needing therapy, most patients are treated with chemotherapy plus rituximab, which has improved response rates, duration of response and overall survival. Randomized studies have shown additional benefit for maintenance rituximab both following chemotherapy-rituximab and single agent rituximab. Experimental therapies as well as stem cell transplantation (SCT) are considered for recurrent disease. Copyright © 2014 Wiley Periodicals, Inc.

In general, cytopenias can occur but constitutional symptoms of fever, nightsweats, and weight loss are uncommon. Diagnosis is based on histology of preferably a biopsy of a lymph node. Immunohistochemical staining is positive in virtually all cases for cell surface CD19, CD20, CD10, and monoclonal immunoglobulin, as well as cytoplasmic expression of bcl-2 protein. The overwhelming majority of cases have the characteristic t(14;18) translocation involving the IgH/bcl-2 genes. The Follicular Lymphoma International Prognostic Index prognostic model for FL uses five independent predictors of inferior survival: age >60 years, hemoglobin  normal, Ann Arbor stage III/IV, number of involved nodal areas > 4. The presence of 0, 1, 2, and ≥ 3 adverse factors defines low, intermediate, and high-risk disease. With the use of more modern therapies, outcomes have improved. Observation continues to be adequate for asymptomatic patients with low bulk disease and no cytopenias, with no survival advantage for early treatment with either chemotherapy or rituximab alone. For patients needing therapy, most patients are treated with chemotherapy plus rituximab, which has improved response rates, duration of response and overall survival. Randomized studies have shown additional benefit for maintenance rituximab both following chemotherapy-rituximab and single agent rituximab. Experimental therapies as well as stem cell transplantation (SCT) are considered for recurrent disease. © 2017 Wiley Periodicals, Inc.

    Full Text Available Abstract Introduction Breast involvement by non-Hodgkin lymphoma is particularly rare in men. We describe the case of a patient with a rapidly growing, painless gynecomastia-like nodule in the left breast. On ultrasonography, the nodule was suspicious for breast carcinoma. Case presentation A breast biopsy from a 54-year-old Caucasian man showed the morphoimmunophenotypical features of grade 3 follicular lymphoma. Moreover, fluorescence in situ hybridization analysis showed a t(14,18 translocation suggesting breast involvement by a systemic lymphoma rather than a primary breast lymphoma. The histological diagnosis was subsequently confirmed after nodule excision. Mediastinal and abdominal node involvement was then identified on computed tomography and positron emission tomography scans during staging examinations. Our patient was treated with chemotherapy. After three years our patient experienced a right retro-areolar relapse. He then received two further cycles of chemotherapy but developed a myeloid acute leukemia and, as a result of this, he subsequently died. Conclusions The rarity of breast lymphomas, especially in men, and the problems related to the therapeutic choices with these tumors require molecular techniques in association with classical histological diagnosis.

    BCL2/IGH rearrangements were analysed by polymerase chain reaction (PCR) at diagnosis in paired peripheral blood (PB) and bone marrow (BM) samples from 67 patients with stage I/II follicular lymphoma (FL). Real time quantitative PCR (RQ-PCR) and digital droplet PCR (ddPCR) were performed in cases with a major breakpoint region (MBR+) at diagnosis and after localized radiotherapy and rituximab administration in order to investigate the applicability of ddPCR. The overall ddPCR/RQ-PCR concordance was 81·9% (113/138 samples) and 97·5% in the 40/138 with quantifiable disease (RQ-PCR≥10 -5 ). At baseline, ddPCR allowed the recovery of a MBR+ marker in 8/18 (44·4%) samples that resulted MBR-negative/minor cluster region-negative/minor BCL2-negative by qualitative PCR. Moreover, the tumour burden at diagnosis significantly predicted progression-free survival (PSF) only when quantified by ddPCR. Paired PB and BM samples analysis demonstrated a high concordance in the detection of BCL2/IGH+ cells by qualitative and quantitative methods; in particular, 40/62 samples were positive by ddPCR (25 PB+/BM+; 9 PB+/BM-; 6 PB-/BM+), with 34/40 (85%) identified by the study of PB only. In conclusion, in localized FL, ddPCR is a promising tool for monitoring minimal residual disease (MRD) that is at least comparable to RQ-PCR and potentially more accurate. PB is a suitable source for serial BCL2/IGH MRD assessments, regardless of the methodology utilized. © 2017 John Wiley & Sons Ltd.

    Full Text Available Follicular lymphoma (FL is an indolent malignancy of germinal center B cells with varied incidence across racial groups and geographic regions. Improvements in the classification of non-Hodgkin lymphoma subtypes provide an opportunity to explore associations between environmental exposures and FL incidence. Our paper found that aspects of Western lifestyle including sedentary lifestyle, obesity, and diets high in meat and milk are associated with an increased risk of FL. Diets rich in fruits and vegetables, polyunsaturated fatty acids, vitamin D, and certain antioxidants are inversely associated with FL risk. A medical history of Sjogren's syndrome, influenza vaccination, and heart disease may be associated with FL incidence. Associations between FL and exposure to pesticides, industrial solvents, hair dyes, and alcohol/tobacco were inconsistent. Genetic risk factors include variants at the 6p21.32 region of the MHC II locus, polymorphisms of the DNA repair gene XRCC3, and UV exposure in individuals with certain polymorphisms of the vitamin D receptor. Increasing our understanding of risk factors for FL must involve integrating epidemiological studies of genetics and exposures to allow for the examination of risk factors and interactions between genes and environment.

    Follicular Lymphoma (FL) is a cancer arising from the lymphatic system. Originating from follicle center B cells, FL is mainly comprised of centrocytes (usually middle-to-small sized cells) and centroblasts (relatively large malignant cells). According to the World Health Organization's recommendations, there are three histological grades of FL characterized by the number of centroblasts per high-power field (hpf) of area 0.159 mm2. In current practice, these cells are manually counted from ten representative fields of follicles after visual examination of hematoxylin and eosin (H&E) stained slides by pathologists. Several studies clearly demonstrate the poor reproducibility of this grading system with very low inter-reader agreement. In this study, we are developing a computerized system to assist pathologists with this process. A hybrid approach that combines information from several slides with different stains has been developed. Thus, follicles are first detected from digitized microscopy images with immunohistochemistry (IHC) stains, (i.e., CD10 and CD20). The average sensitivity and specificity of the follicle detection tested on 30 images at 2×, 4× and 8× magnifications are 85.5+/-9.8% and 92.5+/-4.0%, respectively. Since the centroblasts detection is carried out in the H&E-stained slides, the follicles in the IHC-stained images are mapped to H&E-stained counterparts. To evaluate the centroblast differentiation capabilities of the system, 11 hpf images have been marked by an experienced pathologist who identified 41 centroblast cells and 53 non-centroblast cells. A non-supervised clustering process differentiates the centroblast cells from noncentroblast cells, resulting in 92.68% sensitivity and 90.57% specificity.

    Purpose/Objective: About (2(3)) of all cases of follicular lymphoma have rearrangement of bcl-2 MBR through t(14;18) (q32;q21). This arrangement could serve as a sensitive marker for follicular lymphoma cells. The objectives of this study are two fold: 1) To assess complete molecular response rate of stages I-III follicular lymphoma to CLI by detection of PCR amplifiable bcl-2 MBR rearrangement in the bone marrow and peripheral blood before and after CLI. 2) To assess the significance of the molecular response as a prognostic indicator. Materials and Methods: 13 patients with stages I-III follicular lymphoma were treated with CLI as a part of a prospective randomized protocol comparing CLI with chemotherapy. Bone marrow and peripheral blood samples were obtained from the patients before initiation of CLI. By using the PCR technique, the DNA sequences from the bone marrow and peripheral blood samples that flank the bcl-2 MBR involved in t(14;18) (q32;q21) were amplified. For the patients who had positive PCR result, bone marrow and blood samples were followed at regular intervals during and after CLI. The patients with negative PCR result prior to CLI did not have follow-up PCR analysis. The results of the PCR amplification were correlated with clinical findings. Results: All 13 patients achieved clinical complete response after CLI. No patient has relapsed with a median follow-up period of 11 months (range 5 to 24 months). Pretreatment PCR results are available in 13 patients for peripheral blood and in 9 patients for bone marrow. (7(13)) blood and (5(9)) bone marrow samples were PCR-positive for bcl-2 MBR rearrangement. All 5 patients with positive pretreatment bone marrow also had positive pretreatment peripheral blood. (6(7)) patients with positive pretreatment blood PCR converted to negative within 2,3,5,6,6, and 10 months from the 1st day of CLI. The 7th patient has no follow-up PCR available yet.

    Full Text Available An unusual and well-characterised case of composite lymphoma in the spleen and lymph node is presented. The simultaneous occurrence of mixed-cellularity Hodgkin's lymphoma (HL and follicular non-Hodgkin's lymphoma (NHL was demonstrated in a 66-year-old man admitted in our Service with anaemia, hepatosplenomegaly and multiple abdominal lymph nodes. The morphological study of the spleen and lymph node of the splenic hilum showed an infiltrate composed of two distinct neoplasias. The liver was involved by NHL infiltrate and the peripancreatic lymph node exhibited HL. The Reed-Sternberg (RS cells expressed CD 15 and CD 30, whereas the NHL cells presented standard immunohistochemical features of follicular lymphoma. To our knowledge, this is the fifth case report of concurrent spleen involvement by composite lymphoma. The incidence, clinicopathological and immunohistochemical features of this rare association are discussed.

    Intraoral presentation of follicular lymphoma is rare, and only three cases in the palate have been reported to date. The present case report describes an uncommon case of follicular lymphoma affecting the palate. The clinical aspect was similar to salivary gland neoplasm, and an incisional biopsy was important to establish the correct diagnosis and consequently to plan the treatment. Also discussed is the differential diagnosis among follicular lymphoma, mucosa-associated lymphoid tissue lymphoma, and follicular lymphoid hyperplasia with regard to the histopathologic and immunohistochemical features.

    Follicular lymphoma (FL) is the most common indolent lymphoma, and it has a long median overall survival (OS). However, the recent discovery of clinical and biological prognostic biomarkers in FL is shedding light on FL heterogeneity and the need for a precise and risk-stratified individual approach at diagnosis and relapse. Many FL patients who are asymptomatic with indolent disease can be vulnerable to the toxicity, emotional distress, and financial burden of overtreatment. Yet a subset of FL patients develop chemoresistance to standard chemoimmunotherapy, experience transformation to aggressive lymphoma and rapid progression, and represent the population most in need of novel therapies and curative approaches. Novel biomarkers that incorporate both clinical and genetic determinants of poor risk are being developed with the hope of identifying high-risk patients at diagnosis in order to offer biologically rational targeted therapies. © 2016 by The American Society of Hematology.

    2017-05-01

    Full Text Available Several infectious agents appear to provide a proliferative signal -- “antigen-drive” – that  could be implicated in the pathogenesis of various type of Non-Hodgkin Lymphoma (NHL. A classical model of infection-driven lymphoprolipherative disorder is Helicobacter pylori-induced gastric MALT lymphoma, where antibiotic therapy allows eradication of both the infectious agent and the clonal B-cell expansion;  following the footsteps of these example, several retrospective studies have found a correlation with other pathogens and B-cell Lymphomas, adding new important informations about pathogenesis and laying the groundwork for chemotherapy-free treatments. Although no clear association with infectious agents has yet been identified for Follicular Lymphoma (FL, a growing number of biological and clinical observations suggests that interaction with physiological and pathological microbial populations might play a role also in this subtype of lymphoma: in the last years epidemiological studies investigating the association of known risk factors and FL found a potential correlation with viral or bacterial infections; moreover recent findings about the stimulation of FL clones support the importance of microbial exposure to lymphomagenesis and disease progression. In the following review we make an attempt to find tangible evidences in favor of a role of either physiological and pathological exogenous microbial species in the pathogenesis of FL, and try to integrate the findings coming from epidemiological, biological and interventional studies to define future  novel treatment and prevention strategies for FL.

    Purpose The FOLL05 trial compared R-CVP (rituximab plus cyclophosphamide, vincristine, and prednisone) with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) and R-FM (rituximab plus fludarabine and mitoxantrone) regimens without rituximab maintenance as initial therapy for patients with advanced-stage follicular lymphoma (FL). A previous analysis with a median follow-up of 34 months showed a superior 3-year time to treatment failure, the primary study end point, with R-CHOP and R-FM versus R-CVP and showed R-CHOP to have a better risk-benefit ratio in terms of toxicity than R-FM. We report a post hoc analysis of this trial after a median follow-up of 7 years. Patients and Methods Of the 534 enrolled patients, 504 were evaluable. At the time of analysis, the median follow-up was 84 months (range, 1 to 119 months). Results The 8-year time to treatment failure and progression-free survival rates were 44% (95% CI, 39% to 49%) and 48% (95% CI, 43% to 53%), respectively. The hazard ratio for progression-free survival adjusted by FL International Prognostic Index 2 versus R-CVP was 0.73 for R-CHOP (95% CI, 0.54 to 0.98; P = .037) and 0.67 for R-FM (95% CI, 0.50 to 0.91; P = .009). The 8-year overall survival (OS) rate was 83% (95% CI, 79% to 87%), with no significant differences among study arms. Overall, we observed a higher risk of dying as a result of causes unrelated to lymphoma progression with R-FM versus R-CVP. Conclusion With an 83% 8-year OS rate, long-term follow-up of the FOLL05 trial confirms the favorable outcome of patients with advanced-stage FL treated with immunochemotherapy. The three study arms had similar OS but different activity and toxicity profiles. Patients initially treated with R-CVP had a higher risk of lymphoma progression compared with those receiving R-CHOP, as well as a higher risk of requiring additional therapy.

  1. Intralesional rituximab in primary conjunctival follicular lymphoma relapsed.

    A 49-year-old woman experienced a local relapse of a primary follicular lymphoma (FL) of the conjunctiva. She received 4 weekly intra-lesional injections followed by 6 monthly injections of rituximab (6mg/ml). A clinical response was achieved after first injection. No adverse ocular event or signs of lymphoma relapse were seen after 10 months of follow-up. Intralesional administration of rituximab for treating primary FL of the conjunctiva was an effective and safe therapeutic option; therefore it could be an alternative to other conventional treatments, such as radiotherapy or chemotherapy.

    It is not very often to see a symbol-based machine learning approach to be used for the purpose of image classification and recognition. In this paper we will present such an approach, which we first used on the follicular lymphoma images. Lymphoma is a broad term encompassing a variety of cancers of the lymphatic system. Lymphoma is differentiated by the type of cell that multiplies and how the cancer presents itself. It is very important to get an exact diagnosis regarding lymphoma and to determine the treatments that will be most effective for the patient's condition. Our work was focused on the identification of lymphomas by finding follicles in microscopy images provided by the Laboratory of Pathology in the University Hospital of Tenerife, Spain. We divided our work in two stages: in the first stage we did image pre-processing and feature extraction, and in the second stage we used different symbolic machine learning approaches for pixel classification. Symbolic machine learning approaches are often neglected when looking for image analysis tools. They are not only known for a very appropriate knowledge representation, but also claimed to lack computational power. The results we got are very promising and show that symbolic approaches can be successful in image analysis applications.

    2006-01-01

    The International Prognostic Index (IPI) is the most commonly used prognostic model for mantle cell lymphoma (MCL). However, the prognostic value of the IPI is limited. The recently published Follicular Lymphoma International Prognostic Index (FLIPI) is built on variables, which are pertinent...... to MCL. This study was conducted to evaluate the prognostic value of FLIPI in a population-based series of 93 patients with MCL diagnosed in a 7-year period. End points of the study were response to therapy, overall survival, and disease-free survival (DFS) according to the IPI and FLIPI. Applied...... to the whole series, the FLIPI identified three risk groups with markedly different outcome with 5-year overall survival rates of 65%, 42%, and 8% respectively. Notably, the high-risk group comprised 53% of patients. In contrast, the IPI only allocated 16% of cases to the high-risk group and had a lower...

    The metabolism of folate is essential in DNA synthesis, and polymorphisms of genes involved in such metabolism have been implicated in many types of cancer. Among these, the methylene tetrahydrofolate reductase gene (MTHFR) encodes an enzyme that converts folate to a methyl donor used for DNA methylation. We studied the association between the different genotypes of the two most common MTHFR polymorphisms, C677T and A1298C, and the risk of follicular lymphoma (FL). For this purpose, 55 previously diagnosed FL patients and 170 normal control subjects were examined using polymerase chain reaction followed by restriction fragment length polymorphism. The frequency of the A1298C CC homozygous mutant genotype was significantly higher in patients with FL than in control subjects (OR = 3.51, 95% CI = 1.39-8.86, P = 0.008). No such association was found for the heterozygous A1298C AC genotype (OR = 1.08, 95% CI = 0.55-2.12, P = 0.83). On the other hand, no significant association was found for either the C677T CT heterozygous genotype (OR = 0.79, 95% CI = 0.42-1.51, P = 0.49) or the C677T TT homozygous mutant genotype (OR = 0.55, 95% CI = 0.12-2.65, P = 0.46). The present findings add to the very few reports suggesting a link between the A1298C CC homozygous MTHFR genotype and a higher risk of developing FL, and the first such in a Jordanian population.

    2017-06-02

    BACKGROUND Follicular B cell lymphomas account for a significant portion of all newly diagnosed non-Hodgkin's lymphomas. While involvement can be varied, the most common extranodal presentation is within the gastrointestinal tract beyond the stomach. In addition, the stomach has a diffuse multivessel vascular supply, which decreases the likelihood of developing ischemic gastritis. CASE REPORT An 89-year-old woman with history of diabetes, deep venous thromboembolism, and hypertension was referred due to a newly diagnosed retroperitoneal mass. Biopsy of a left para-aortic node was consistent with low-grade follicular B cell lymphoma. Following mainstream treatment guidelines, rituximab was administered. Approximately 12 hours later, the patient presented to the Emergency Department with intractable vomiting and nausea. After admission, an esophagogastroduodenoscopy (EGD) revealed extensive ischemic gastritis. Due to recurrent ascites requiring frequent paracenteses, and the clinical aggressiveness of the patient's underlying lymphoma, a second dose of rituximab was administered with concurrent initiation of total parenteral nutrition. Approximately 1 week later, the patient underwent a repeat EGD for quality of life planning while in hospice. The repeat EGD revealed resolved ischemic gastritis. Her diet was advanced and she was subsequently discharged home. CONCLUSIONS Rituximab alone shows promise in treating extensive follicular B cell lymphoma complicated by ischemic gastritis, which has not been previously reported in the literature.

    Full Text Available Danielle M Brander, Anne W BeavenDuke University Medical Center, Durham, NC, USAAbstract: Follicular lymphoma is predominantly managed as a chronic disease, with intermittent chemo/immunotherapy reserved for symptomatic progression. It is considered incurable with conventional treatments, and current therapeutic options are associated with significant toxicities that are especially limiting in older patients. Bortezomib (PS-341; Velcade®, a first-in-class drug targeting the proteolytic core subunit of the 26S proteasome, has emerged as a therapeutic alternative in follicular lymphoma, with promising preclinical data and efficacy in patients with other hematological malignancies. Several clinical trials were conducted with bortezomib for the treatment of non-Hodgkin’s lymphoma. As a single agent, overall responses in follicular lymphoma varied greatly (16%–41%, with weekly bortezomib showing less neurotoxicity than twice-weekly regimens, but with concern about decreased responses. Combination with rituximab was projected to improve the efficacy of bortezomib, but this resulted in increased toxicities and questionable added benefit. Although the largest Phase III study in follicular lymphoma of bortezomib plus rituximab versus rituximab alone demonstrated a significant progression-free survival difference, the absolute difference was small (12.8 months versus 11 months. Combining bortezomib with established regimens, such as rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP, rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP, or rituximab-bendamustine also did not show definite benefit, and many of these studies did not meet their primary endpoint when bortezomib failed to improve responses or survival to the degree anticipated. In a disease where the goal of treatment is palliative and affected patients often have other medical and treatment-related comorbidities, decisions regarding therapies

    Full Text Available We report three elderly patients with follicular lymphoma in situ (FLIS each highlighting a unique pattern of disease presentation and progression. The first patient had incidentally detected FLIS with peripheral blood spill and yet had an 11-year uneventful follow up. The second patient with an overt follicular lymphoma (FL developed high-grade transformation in jejunum with FLIS extensively involving the Payers patches. The third patient had a FLIS but that qualified as higher grade and was treated in spite of lack of overt FL mainly because of higher grade and patient subsequently did develop overt FL. The first case of typical FLIS confirms that peripheral blood spill does not connote poor prognosis in FLIS, the second case illustrates that FLIS may colonize mucosa-associated lymphoid tissue as part of homing in process of a disseminated FL and the third case validates the aggressive nature of high-grade FLIS.

    Follicular lymphoma (FL) is the most common type of non-Hodgkin lymphoma (NHL), with indolent progression. Several treatment options are selected, based not only on disease status, quality of life (QOL), and age of patient, but also on recent increasing medical costs. We retrospectively analysed the first-line treatment of FL with regard to treatment outcomes and medical economics, and discuss the appropriate strategies for FL. Data on a total of 69 newly-diagnosed patients with FL was retrospectively collected from 2001 to 2015. The median age of the patients was 60 years and the median follow-up was 58 months. A total of 25 cases with FL were treated with R monotherapy, and 28 cases were treated with R-CHOP as first-line treatment. The factors affecting the decision of physicians to use R or R-CHOP treatment were serum level of lactate dehydrogenase (LDH) and disease stage. The first-line treatment-associated survival did not show any statistical differences between R and R-CHOP. The average hospitalization and average of all medical costs during the first-line treatment were 4.1 days (R) versus 55.7 days (R-CHOP), and JPY 1,707,693 (USD 15,324) (R) versus JPY 2,136,117 (USD 19,170) (R-CHOP), respectively. R monotherapy for patients whose diseases show low tumor burden and who are not candidates for local treatment has benefits as a first-line treatment compared to R-CHOP, based on the patients' QOL and medical economics.

    Full Text Available We have previously shown that regulatory T cells (Tregs infiltrating follicular lymphoma lymph nodes are quantitatively and qualitatively different than those infiltrating normal and reactive nodes. To gain insight into how such Treg populations differ, we performed RNA sequence (RNAseq analyses on flow sorted Tregs from all three sources. We identify several molecules that could contribute to the observed increased suppressive capacity of follicular lymphoma nodal tregs, including upregulation of CTLA-4, IL-10, and GITR, all confirmed by protein expression. In addition, we identify, and confirm functionally, a novel mechanism by which Tregs target to and accumulate within a human tumor microenvironment, through the down regulation of S1PR1, SELL (L-selectin and CCR7, potentially resulting in greater lymph node retention. In addition we identify and confirm functionally the upregulation of the chemokine receptor CXCR5 as well as the secretion of the chemokines CXCL13 and IL-16 demonstrating the unique ability of the follicular derived Tregs to localize and accumulate within not only the malignant lymph node, but also localize and accumulate within the malignant B cell follicle itself. Such findings offer significant new insights into how follicular lymphoma nodal Tregs may contribute to the biology of follicular lymphoma and identify several novel therapeutic targets.

FL is an incurable disease with treatment options ranging from a “watch-and-wait” approach to localized therapy with radiation or systemic therapy with rituximab in combination with chemotherapy regimens. This review summarizes the role of rituximab across the spectrum of FL treatment and the evolving therapeutic landscape with the emergence of novel agents currently in clinical development. Despite the prospect of new agents on the horizon, it is widely accepted that rituximab will remain as the cornerstone of therapy because of its established long-term efficacy. Many biologics, including rituximab, have lost exclusivity of composition-of-matter patent or will do so in the next few years, which is a concern for patients and physicians alike. Moreover, access to rituximab is challenging, particularly in countries with restricted resources. Together, these concerns have fueled the development of safe and effective biosimilars. The term “biosimilar” refers to a biologic product that is highly similar to an approved reference (or originator product, notwithstanding minor differences in clinically inactive components, and for which there are no clinically meaningful differences in purity, potency, or safety. Biosimilars are developed to treat the same condition(s using the same treatment regimens as an approved reference biologic, and have the potential to increase access to more affordable treatment of FL. Herein, we also discuss the potential benefits of eagerly awaited rituximab biosimilars, which may mitigate the impact of the lack of

    Full Text Available Non-Hodgkin lymphoma (NHL represents a diverse group of hematological malignancies, of which follicular lymphoma (FL is a prevalent subtype. A previous genome-wide association study has established a marker, rs10484561 in the human leukocyte antigen (HLA class II region on 6p21.32 associated with increased FL risk. Here, in a three-stage genome-wide association study, starting with a genome-wide scan of 379 FL cases and 791 controls followed by validation in 1,049 cases and 5,790 controls, we identified a second independent FL-associated locus on 6p21.32, rs2647012 (OR(combined  = 0.64, P(combined  = 2 × 10(-21 located 962 bp away from rs10484561 (r(2<0.1 in controls.

Our results reveal the presence of allelic heterogeneity within the HLA class II region influencing FL susceptibility and indicate a possible shared genetic etiology with diffuse large B-cell lymphoma.

    Malignant lymphomas are lympho-proliferative diseases in which the well-defined clinical pattern of Hodgkin's disease is contrasted by the heterogeneous group of lymphomas of the non-Hodgkin type. A simplified form of the sub-classification of Hodgkin's disease suggested in 1966 by Lukes and Butler, has found world-wide recognition. However, no generally accepted classification scheme has been evolved so far for the histological classification of other lymphomas, and this leads to considerable difficulties when comparing the therapy results from different centres. Precise histological classification and accurate staging before onset of therapy enable well-defined pronoses and therapy planning in line with case requirements. Radiological methods (X-ray chest, sonography, computed tomography, lymphography, scintigraphy etc.) are important in diagnosis required for accurate staging. (orig.) [de

    Follicular lymphoma (FL) is an indolent B-cell non-Hodgkin lymphoma able to transform into germinal center-type diffuse large B-cell lymphoma. We describe four extraordinary cases of FL, which progressed to TdT + CD20 - precursor B-lymphoblastic lymphoma (B-LBL). Fluorescence in situ hybridization analysis showed that all four B-LBLs had acquired a MYC translocation on transformation. Comparative genomic hybridization analysis of one case demonstrated that in addition to 26 numerical aberrations that were shared between the FL and B-LBL, deletion of CDKN2A/B and 17q11, 14q32 amplification, and copy-neutral loss of heterozygosity of 9p were gained in the B-LBL cells. Whole-exome sequencing revealed mutations in FMN2, NEB, and SYNE1 and a nonsense mutation in KMT2D, all shared by the FL and B-LBL, and TNFRSF14, SMARCA2, CCND3 mutations uniquely present in the B-LBL. Remarkably, all four FL-B-LBL pairs expressed IgG. In two B-LBLs, evidence was obtained for ongoing rearrangement of IG light chain variable genes and expression of the surrogate light chain. IGHV mutation analysis showed that all FL-B-LBL pairs harbored identical or near-identical somatic mutations. From the somatic gene alterations found in the IG and non-IG genes, we conclude that the FLs and B-LBLs did not develop in parallel from early t(14;18)-positive IG-unmutated precursors, but that the B-LBLs developed from preexistent FL subclones that accumulated additional genetic damage.

    This guideline is a prerequisite for the quality management in the treatment of non-Hodgkon-lymphomas in patients with relapsed or refractory follicular lymphoma after rituximab therapy and as consolidation therapy after first remission following CHOP like treatment using radioimmunotherapy. It is based on an interdisciplinary consensus and contains background information and definitions as well as specified indications and detailed contraindications of treatment. Essential topics are the requirements for institutions performing the therapy. For instance, presence of an expert for medical physics, intense cooperation with all colleagues committed to treatment of lymphomas, and a certificate of instruction in radiochemical labelling and quality control are required. Furthermore, it is specified which patient data have to be available prior to performance of therapy and how treatment has to be carried out technically. Here, quality control and documentation of labelling are of great importance. After treatment, clinical quality control is mandatory (work-up of therapy data and follow-up of patients). Essential elements of follow-up are specified in detail. The complete treatment inclusive after-care has to be realised in close cooperation with those colleagues (hemato-oncologists) who propose, in general, radioimmunotherapy under consideration of the development of the disease.

    In most human lymphomas, the chromosome translocation t(14;18) occurs within two breakpoint clustering regions on chromosome 18, the major one at the 3' untranslated region of the bcl-2 gene and the minor one at 3' of the gene. Analysis of a panel of follicular lymphoma DNAs using probes for the first exon of the bcl-2 gene indicates that DNA rearrangements may also occur 5' to the involved bcl-2 gene. In this case the IgH locus and the bcl-2 gene are found in an order suggesting that an inversion also occurred during the translocation process. The coding region of the bcl-2 gene, however, are left intact in all cases of follicular lymphoma studied to date

    (90) Yttrium ((90) Y)-Ibritumomab-Tiuxetan combines the targeting advantage of a monoclonal antibody with the radiosensitivity of Follicular Lymphoma (FL). Previous studies showed that 90Y-IT is safe and effective in relapsed/refractory indolent FL, irrespective of prior treatment with rituximab. This multicentre trial aimed to evaluate the safety and the efficacy of "upfront" single-agent ((90) Y)-Ibritumomab-Tiuxetan in advanced-stage FL. The primary objective was the incidence of responses in terms of complete (CR) and partial remission (PR). Fifty patients with stage II "bulky", III or IV FL received a single treatment course with ((90) Y)-Ibritumomab-Tiuxetan as initial therapy. The median age was 60 years. Bone marrow involvement (90%, respectively. Grade 3/4 neutropenia and thrombocytopenia occurred in 30% and 26% of patients respectively; none experienced grade 3/4 non-haematological toxicity. No cases of secondary haematological malignancies were observed. ((90) Y)-Ibritumomab-Tiuxetan was demonstrated to be highly effective and safe as first-line treatment for advanced-stage FL. © 2013 John Wiley & Sons Ltd.

After 2 decades of use, rituximab is firmly positioned in the treatment of follicular lymphoma (FL, both in the front line and in the relapsing disease, improving previous results by including it in classical chemotherapy regimens. However, the pharmacology of rituximab continues to generate controversial issues especially regarding the mechanisms of action in vivo. The contribution of rituximab as a maintenance treatment in FL has been significant progress in the management of this disease without an increase in side effects or a decrease in the quality of life of patients. With the widespread use of rituximab, there are new security alerts and side effects not previously detected in the pivotal trials that clinicians should learn to recognize and manage. In this article, we will review the pharmacokinetics and pharmacodynamics of rituximab, the management issues in the treatment of advanced FL focusing on maintenance rituximab, its long-term efficacy and safety profile, and its effect on the quality of life.

    A linear progression model of follicular lymphomas (FL) FL1, FL2 and FL3A has been favored, since FL 3A often coexist with a FL1/2 component. FL3B, in contrast, is thought to be more closely related to diffuse large B-cell lymphoma (DLBCL), and both FL3B and DLBCL are often simultaneously present in one tumor (DLBCL/FL3B). To obtain more detailed insights into FL progression, comprehensive analysis of a well-defined set of FL1/2 (n=22), FL3A (n=16), FL3B (n=6), DLBCL/FL3B (n=9) and germincal center B-cell(GCB)-type DLBCL (n=45) was performed using gene expression profiling, immunohistochemical staining and genetic analysis by fluorescence in situ hybridization (FISH). While immunohistochemical (CD10, IRF4/MUM1, Ki67, BCL2, BCL6) and genetic profiles (translocations of BCL2, BCL6 and MYC) delineate FL1-3A from FL3B and DLBCL/FL3B, significant differences were observed between FL1/2 and FL3A upon gene expression profiling (GEP). Interestingly, FL3B turned out to be closely related to FL3A, not categorizing within a separate GE cluster, and both FL3A and FL3B showed overlapping profiles in between FL1/2 and DLBCL. Finally, basing upon their gene expression pattern, DLBCL/FL3B represents a composite form of FL3B and DLBCL, with the majority of samples more closely resembling DLBCL. The fact that gene expression profiling clearly separated FL1/2 from both FL3A and FL3B suggests a closer biological relationship of the latter. This notion, however, stands in a certain contrast to immunohistochemical and genetic profiles of the different histologic FL subtypes that point to a closer relationship of FL1/2 and FL3A, and separating them from FL3B.

    Salvage of young patients with follicular lymphoma (FL) after R-CHOP includes salvage immunochemotherapy followed by autologous stem cell transplantation (ASCT). Previous studies dealing with relapsed Hodgkin lymphoma have shown the prognostic value of PET/CT prior to ASCT. We retrospectively analysed 59 patients with refractory/relapsed FL after first-line R-CHOP who were chemosensitive (as evaluated by CT) to the salvage treatment and who proceeded to ASCT. The role of PET/CT in this setting to define chemosensitivity is not definitely established. So we focused on the prognostic value of PET/CT performed after salvage treatment, before ASCT. The estimated 3-year progression-free survival (PFS) and overall survival were 63.1 % (50.9-78.3 %) and 90.5 % (82.8 - 98.8 %), respectively, and did not differ significantly according to their Follicular Lymphoma International Prognostic Index at relapse, conditioning regimen, or type of salvage. PFS was significantly lower in PET/CT-positive patients, according to the International Harmonization Project revised response criteria, with a 3-year PFS of 45.5 % (26.6 - 77.8 %) versus 72.6 % (58.5 - 90.0 %; p = 0.039). To better refine prognosis, we applied two types of thresholds: a Deauville five-point scale positive threshold of ≥3 (3-year PFS of 74.9 %, range 61.0 - 92.1 % %, versus 42.8 %, range 24.7 - 74.4 %; p = 0.02), and a ≥70 % ∇SUV{sub max} threshold between presalvage and pre-ASCT PET/CT (3-year PFS of 72.4 %, range 57.5 - 91.3 % versus 13.3 %, 2.2 - 81.7 %; p < 10{sup -3}). The PET/CT findings before ASCT were independently correlated with PFS in our series. PET/CT negativity before ASCT is a desirable and achievable goal in the management of chemosensitive FL relapsing after first-line R-CHOP. (orig.)

    TET2 (Ten Eleven Translocation 2) is a dioxygenase that converts methylcytosine (mC) to hydroxymethylcytosine (hmC). TET2 loss-of-function mutations are highly frequent in subtypes of T-cell lymphoma that harbor follicular helper T (Tfh)-cell-like features, such as angioimmunoblastic T-cell lymphoma (30–83%) or peripheral T-cell lymphoma, not otherwise specified (10–49%), as well as myeloid malignancies. Here, we show that middle-aged Tet2 knockdown (Tet2 gt/gt ) mice exhibit Tfh-like cell overproduction in the spleen compared with control mice. The Tet2 knockdown mice eventually develop T-cell lymphoma with Tfh-like features after a long latency (median 67 weeks). Transcriptome analysis revealed that these lymphoma cells had Tfh-like gene expression patterns when compared with splenic CD4-positive cells of wild-type mice. The lymphoma cells showed lower hmC densities around the transcription start site (TSS) and higher mC densities at the regions of the TSS, gene body and CpG islands. These epigenetic changes, seen in Tet2 insufficiency-triggered lymphoma, possibly contributed to predated outgrowth of Tfh-like cells and subsequent lymphomagenesis. The mouse model described here suggests that TET2 mutations play a major role in the development of T-cell lymphoma with Tfh-like features in humans

    The main subject of this thesis is the evaluation of radiologic techniques in staging patients with newly diagnosed and untreated malignant lymphoma, or restaging patients with recurrent disease after a period of complete remission. Lymphography and, more recently, CT are available to examine the infradiaphragmatic nodes. CT also offers the possibility to examine other organ systems in the abdomen, and to visualize more lymph-node regions than lymphography. In ch. 2 and 4 the diagnostic performance of CT and lymphography in HD and NHL respectively are discussed. Literature data are summarized, and own results are given. The main goal is to determine whether the two methods are overlapping, competitive or complementary, and to answer the question what would be required for optimal staging. Staging laparotomy showed the unreliability of non-invasive examination methods for determining the presence or absence of lymphoma in the spleen. In ch. 3 and 5 the results of CT-based estimations of size of the spleen in relation to its histologic state, in patients with HD and NHL respectively are presented. The chest can be examined for lymphoma by conventional radiography, conventional tomography or computed tomography (CT). In ch. 6 the literature is reviewed, and the results with our patients are presented. The diagnostic performance of each examination is evaluated, and the results are analysed to define the most desirable approach in the examination of the chest for staging purposes. In ch. 7 the uncommon radiologic observation of calcification in lymph nodes, afflicted with HD and NHL is described. The literature is reviewed, and the clinical significance is indicated. 180 refs.; 22 figs.; 24 tabs

Currently this antibody is licensed in the European Union for use in relapsed or refractory FL. It is anticipated that this drug will also be approved for use as consolidation therapy after successful first-line treatment. Here we first will review the published literature supporting the use of 90Y-ibritumomab tiuxetan in the aforementioned indications and emerging data showing applicability of ibritumomab tiuxetan as sole first-line therapy for FL, as well as in the transplant setting. Possible strategies of incorporating ibritumomab tiuxetan into the treatment algorithm of FL are discussed.Keywords: follicular lymphoma, 90Y-ibritumomab tiuxetan

    Full Text Available Background/Aim. The widely accepted Follicular Lymphoma International Prognostic Index (FLIPI divides patients into three risk groups based on the score of adverse prognostic factors. The estimated 5-year survival in patients with a high FLIPI score is around 50%. The aim of this study was to analyse the prognostic value of clinical and laboratory parameters that are not included in the FLIPI and the New Prognostic Index for Follicular Lymphoma developed by the International Follicular Lymphoma Prognostic Factor Project (FLIPI2 indices, in follicular lymphoma (FL patients with a high FLIPI score and high tumor burden. Methods. The retrospective analysis included 57 newly diagnosed patients with FL, a high FLIPI score and a high tumor burden. All the patients were diagnosed and treated between April 2000 and June 2007 at the Clinic for Hematology, Clinical Center of Serbia, Belgrade. Results. The patients with a histological grade > 1, erythrocyte sedimentation rate (ESR ± 45 mm/h and hypoalbuminemia had a significantly worse overall survival (p = 0.015; p = 0.001; p = 0.008, respectively, while there was a tendency toward worse overall survival in the patients with an Eastern Cooperative Oncology Group (ECOG > 1 (p = 0.075. Multivariate Cox regression analysis identified a histological grade > 1, ESR ± 45 mm/h and hypoalbuminemia as independent risk factors for a poor outcome. Based on a cumulative score of unfavourable prognostic factors, patients who had 0 or 1 unfavourable factors had a significantly better 5-year overall survival compared to patients with 2 or 3 risk factors (75% vs 24.1%, p = 0.000. Conclusion. The obtained results suggest that from the examined prognostic parameters histological grade > 1, ESR ± 45 mm/h and hypoalbuminemia can contribute in defining patients who need more aggressive initial treatment approach, if two or three of these parameters are present on presentation.

    Background Allogeneic hematopoietic stem cell transplantation is an effective treatment for patients with poor risk lymphoma, at least in part because of the graft-versus-lymphoma effect. Over the past decade, reduced intensity conditioning regimens have been shown to offer results similar to those of conventional high-dose conditioning regimens but with lower toxicity early after transplantation, especially in patients with chemosensitive disease at transplant. Design and Methods The aim of this study was to analyze the long-term outcome of patients with follicular lymphoma who received an HLA identical sibling allogeneic stem cell transplant with a reduced intensity conditioning regimen within prospective trials. The prospective multicenter studies considered included 37 patients with follicular lymphoma who underwent allogeneic stem cell transplantation between 1998 and 2007 with a fludarabine plus melphalan-based reduced intensity conditioning regimen. Results The median age of the patients was 50 years (range, 34–62 years) and the median follow-up was 52 months (range, 0.6 to 113 months). Most patients (77%) had stage III-IV at diagnosis, and patients had received a median of three lines of therapy before the reduced intensity conditioning allogeneic stem cell transplantation. At the time of transplantation, 14 patients were in complete remission, 16 in partial remission and 7 had refractory or progressive disease after salvage chemotherapy. The 4-year overall survival rates for patients in complete remission, partial remission, or with refractory or progressive disease were 71%, 48% and 29%, respectively (P=0.09), whereas the 4-year cumulative incidences of non-relapse mortality were 26% (95% CI, 11–61), 33% (95% CI, 16–68) and 71% (95% CI, 44–100), respectively. The incidence of relapse for the whole group was only 8% (95% CI, 2–23). Conclusions We conclude that this strategy of reduced intensity conditioning allogeneic stem cell transplantation

    The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used in the identification of risk groups among follicular lymphoma (FL) patients. The aim of the present study was to evaluate the prognostic value of FLIPI combined with the Charlson comorbidity index (CCI) and histological grade of lymphoma. 224 newly diagnosed FL patients (median age 56 years) treated with immunochemotherapy were retrospectively analysed. Low FLIPI had 21.0 % of patients, intermediate 28.1 % and high 46.9 %. 50.9 % of patients had no comorbidities. Only 7.1 % of patients had a high CCI score (≥2), while 25.9 % of patients were histological grade 3. Parameters that influenced overall survival were evaluated using Cox regression analysis, in which CCI, FLIPI and histological grade (p < 0.05) retained prognostic significance. By combining these parameters, we have developed the FCG score, which incorporates FLIPI, CCI, and histological grade. This score defines three risk categories (low: 41.5 %; intermediate: 37.5 %; high: 13.4 %), associated with significantly different survival (p < 0.0001); this consequently improves discriminative power by 9.1 % compared to FLIPI. FCG score represents a possible new prognostic index, highlighting the role of the patient's clinical state and the histological characteristics of disease, as indicated by comorbidity index and histological grade of lymphoma.

    Full Text Available Abstract Background B-cell non-Hodgkin lymphoma represents a diverse group of hematological malignancies, of which follicular lymphoma (FL is one of the most common subtypes. Family and epidemiological studies suggest an important genetic role in the etiology of FL. In recent genome-wide association studies (GWAS of FL, several genetic susceptibility loci have been identified on chromosome 6p21.33 (rs6457327 and 6p21.32 (rs10484561, rs2647012 in the human leukocyte antigen class I and class II regions. To identify new genetic variants and further elucidate the genetic basis of FL, a meta-analysis was performed of the top 1000 SNPs associated with FL risk from two GWAS in the US, Denmark and Sweden (592 cases, 1541 controls, with independent validation in 107 cases and 681 controls. Results rs9275517 and rs3117222 in the HLA class II region were validated and inversely associated with FL risk (rs9275517: OR = 0.63, 95% CI = 0.55-0.73, p = 4.03 × 10-11; rs3117222: OR = 0.66, 95% CI = 0.57-0.77, p = 1.45 × 10-7. rs9275517, which is in high linkage disequilibrium with rs2647012 (r2 = 0.9, was no longer associated with FL after conditioning on rs2647012. The rs3117222 association was independent of established FL SNPs, but not of the HLA-DPB1*0301 allele. Using publicly available gene expression profiles with matching genotype information, we found that rs3117222 also was significantly correlated with increased HLA-DPB1 expression. Conclusions By performing a meta-analysis of two GWAS of FL, we further validated the relevance of HLA-DPB1*0301 as a protective allele in the pathogenesis of FL. Moreover, the protective rs3117222 A allele correlated with increased levels of HLA-DPB1, suggesting a possible disease mechanism involving HLA-DPB1 expression regulation. Our results add further support to the major role of HLA genetic variation in the pathogenesis of FL.

    Low-grade follicular lymphoma (FL) (grade 1/2, FL1/2) has an annual risk of transformation of ≈3%, which is associated with aberrations in CDKN2A/B, TP53, and MYC. As in diffuse large B-cell lymphoma, high MYC expression in transformed FL (tFL) might predict a MYC breakpoint. We quantified MYC expression by immunohistochemistry and digital analysis in 41 paired biopsies from 20 patients with FL1/2 with subsequent transformation and in four isolated biopsies of tFL. As controls, 28 biopsies of FL1/2 without transformation (median follow-up of 105 months) and nine biopsies of FL3A/B were analysed. In the 20 FL1/2-tFL pairs, MYC expression was significantly higher in tFL than in the initial FL1/2 biopsies (median 54% versus 6%; 7% in FL3A, and 35% in FL3B). MYC breaks (MYC-R) were detected in eight of 21 (38%) tFLs analysed by fluorescence in-situ hybridization (FISH), with a median MYC score of 86%. In two of the analysed tFL cases, the translocation was already detected in antecedent FL1/2. MYC partners were immunoglobulin (IG) loci in three of eight cases (one IGL, one IGH, and one IGK) and non-IG in five of eight cases (two PAX5, one BCL6, and two unknown). Of the eight MYC-R+ cases, six were BCL2+/MYC+ double-hit, one was BCL2+/BCL6+/MYC+ triple-hit, and one was MYC+ single-hit. All three IG-MYC+ cases showed a MYC expression level of >85%, whereas the five cases with a non-IG MYC partner had a wider range of expression (median 68%, range 13-86%). Among the 13 MYC-R- tFLs, two groups with almost dichotomous MYC expression could be observed (three cases showed ≥90% MYC expression), suggesting alternative mechanisms of MYC activation. we show an increase in MYC expression from FL1/2 to tFL. MYC breakpoints were present in ≈40% of the cases, which is markedly higher than in de novo DLBCL. MYC expression was uniformly high in cases with an IG-MYC translocation but much more heterogeneous and in part independent of the presence of a MYC break in non-IG-MYC and

    Immunohistochemical detection of FOXP3 antigen is a usable marker for detection of regulatory T lymphocytes (TR) in formalin fixed and paraffin embedded sections of different types of tumor tissue. TR plays a major role in homeostasis of normal immune systems where they prevent auto reactivity of the immune system towards the host. This beneficial effect of TR is frequently "hijacked" by malignant cells where tumor-infiltrating regulatory T cells are recruited by the malignant nuclei to inhibit the beneficial immune response of the host against the tumor cells. In the majority of human solid tumors, an increased number of tumor-infiltrating FOXP3 positive TR is associated with worse outcome. However, in follicular lymphoma (FL) the impact of the number and distribution of TR on the outcome still remains controversial. In this study, we present a novel method to detect and enumerate nuclei from FOXP3 stained images of FL biopsies. The proposed method defines a new adaptive thresholding procedure, namely the optimal adaptive thresholding (OAT) method, which aims to minimize under-segmented and over-segmented nuclei for coarse segmentation. Next, we integrate a parameter free elliptical arc and line segment detector (ELSD) as additional information to refine segmentation results and to split most of the merged nuclei. Finally, we utilize a state-of-the-art super-pixel method, Simple Linear Iterative Clustering (SLIC) to split the rest of the merged nuclei. Our dataset consists of 13 region-ofinterest images containing 769 negative and 88 positive nuclei. Three expert pathologists evaluated the method and reported sensitivity values in detecting negative and positive nuclei ranging from 83-100% and 90-95%, and precision values of 98-100% and 99-100%, respectively. The proposed solution can be used to investigate the impact of FOXP3 positive nuclei on the outcome and prognosis in FL.

    This work evaluates the performance of a multi-stage image enhancement, segmentation, and classification approach for lymphoma recognition in hematoxylin and eosin (H and E) stained histopathology slides of excised human lymph node tissue. In the first stage, the original histology slide undergoes various image enhancement and segmentation operations, creating an additional 5 images for every slide. These new images emphasize unique aspects of the original slide, including dominant staining, staining segmentations, non-cellular groupings, and cellular groupings. For the resulting 6 total images, a collection of visual features are extracted from 3 different spatial configurations. Visual features include the first fully connected layer (4096 dimensions) of the Caffe convolutional neural network trained from ImageNet data. In total, over 200 resultant visual descriptors are extracted for each slide. Non-linear SVMs are trained over each of the over 200 descriptors, which are then input to a forward stepwise ensemble selection that optimizes a late fusion sum of logistically normalized model outputs using local hill climbing. The approach is evaluated on a public NIH dataset containing 374 images representing 3 lymphoma conditions: chronic lymphocytic leukemia (CLL), follicular lymphoma (FL), and mantle cell lymphoma (MCL). Results demonstrate a 38.4% reduction in residual error over the current state-of-art on this dataset.

    Background B-cell activation factor (BAFF) and BAFF-receptor (BAFF-R) play crucial roles in the viability and proliferation of malignant lymphoma cells. Limited information exists regarding expression profiles and the prognostic role of BAFF and BAFF-R in follicular lymphoma (FL). We sought to determine the expression profiles of BAFF and BAFF-R in FL and to evaluate the correlation of BAFF and BAFF-R expression with clinicopathologic characteristics and outcome of FL. Correlation between expression levels of BAFF detected by immunohistochemical (IHC) and serum levels of BAFF was also evaluated. Methods Paraffin-embedded specimens from 115 patients were immunohistochemically examined for BAFF and BAFF-R expression. Expression levels were dichotomized into low versus high categories based on immunostaining intensity. The correlation of BAFF and BAFF-R expression with clinicopathologic characteristics and patient outcome was assessed. Serum levels of BAFF in 35 of the 115 patients with IHC data were measured by Enzyme-linked Immunosorbent assay (ELISA). Results BAFF and BAFF-R were expressed in 88.7% (102/115) and 87.8% (101/115) of the cases, respectively. BAFF expression was significantly correlated with only one clinicopathologic feature: Ann Arbor stage. No significant correlation was found between expression levels of BAFF detected by IHC and serum levels of BAFF detected by ELISA. High expression of BAFF-R, but not BAFF, was significantly correlated with inferior progression-free survival (PFS; P = 0.013) and overall survival (OS; P = 0.03). High expression of BAFF-R, bulky disease, and elevated lactate dehydrogenase were correlated with inferior PFS and OS in multivariate analysis. A prognostic scoring system incorporating these 3 risk factors identified 3 distinct prognostic groups with 5-year PFS of 59.4%, 41.9%, and 10.7% and OS of 91.3%, 79.7%, and 45.8%, respectively. Conclusions Most patients with FL variably express BAFF and BAFF-R. High

    We aimed to compare the standardized central review of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT scans performed after induction therapy for follicular lymphoma (FL) in the PRIMA study (Salles et al., Lancet 377:42-51, 2011; Trotman et al., J Clin Oncol 29:3194-3200, 2011) to scan review at local centres. PET/CT scans were independently evaluated by two nuclear medicine physicians using the 2007 International Harmonization Project (IHP) criteria (Cheson et al., J Clin Oncol 25:579-586, 2007; Juweid et al., J Clin Oncol 25:571-578, 2007; Shankar et al., J Nucl Med 47:1059-1066, 2006) and Deauville 5-point scale (5PS) criteria (Meignan et al., Leuk Lymphoma 50:1257-1260, 2009; Meignan et al., Leuk Lymphoma 51:2171-2180, 2010; Barrington et al., Eur J Nucl Med Mol Imaging 37:1824-1833, 2010). PET/CT status was compared with prospectively recorded patient outcomes. Central evaluation was performed on 119 scans. At diagnosis, 58 of 59 were recorded as positive, with a mean maximum standardized uptake value (SUV{sub max}) of 11.7 (range 4.6-35.6). There was no significant association between baseline SUV{sub max} and progression-free survival (PFS). Sixty post-induction scans were interpreted using both the IHP criteria and 5PS. Post-induction PET-positive status failed to predict progression when applying the IHP criteria [p = 0.14; hazard ratio (HR) 1.9; 95 % confidence interval (CI) 0.8-4.6] or 5PS with a cut-off ≥3 (p = 0.12; HR 2.0; 95 % CI 0.8-4.7). However, when applying the 5PS with a cut-off ≥4, there was a significantly inferior 42-month PFS in PET-positive patients of 25.0 % (95 % CI 3.7-55.8 %) versus 61.4 % (95 % CI 45.4-74.1 %) in PET-negative patients (p = 0.01; HR 3.1; 95 % CI 1.2-7.8). The positive predictive value (PPV) of post-induction PET with this liver cut-off was 75 %. The 42-month PFS for patients remaining PET-positive by local assessment was 31.1 % (95 % CI 10.2-55.0 %) vs 64.6 % (95 % CI 47.0-77.6 %) for PET

    Full Text Available Follicular lymphoma (FL is the second most common histotype of non-Hodgkin’s lymphoma and it is generally characterized by a heterogeneous clinical course. Despite recent therapeutic and diagnostic improvements, a significant fraction of FL patients still relapsed. In younger and/or fit FL relapsed patients bone marrow transplant (BMT has represented the main salvage therapy for many years. Thanks to the ability of high dose chemotherapy to overcome the lymphoma resistance and refractoriness, autologous stem cell transplantation (ASCT is able to achieve a high complete remission rate (CR and favourable outcome in terms of progression free survival (PFS and overall survival (OS. Allogeneic stem cell transplantation (alloSCT combines the high dose chemotherapy effect together with the immune reaction of the donor immune system against lymphoma, the so called ‘graft versus lymphoma’ (GVL effect. Considering the generally higher transplant related mortality (TRM, alloSCT is mostly indicated for FL relapsed after ASCT. During the last years there has been a great spread of novel effective and feasible drugs Although these and future novel drugs will probably change our current approach to FL, the OS post-BMT (ASCT and alloSCT has never been reproduced by any novel combination. In this scenario, it is important to correctly evaluate the disease status, the relapse risk and the comorbidity profile of the relapsed FL patients in order to provide the best salvage therapy and eventually transplant consolidation.

    FilGAP, a Rho GTPase-activating protein (GAP), acts as a mediator of Rho/ROCK (Rho-associated protein kinase)-dependent amoeboid movement, and its knockdown results in Rac-driven mesenchymal morphology. Herein, we focus on the possible roles of FilGAP expression in normal and malignant lymphocytes. Eighty-three cases of follicular lymphoma (FL), 84 of diffuse large B-cell lymphoma (DLBCL), and 25 of peripheral T-cell lymphoma (PTCL), as well as 10 of normal lymph nodes, were immunohistochemically investigated. In normal lymph nodes, FilGAP immunoreactivity was significantly higher in lymphocytes in the mantle zone as compared to those in the germinal center and paracortical areas. In contrast, the expression levels of both cytoplasmic and perinuclear Rac1 were significantly lower in the germinal center as compared to paracortical regions, suggesting that changes in the FilGAP/Rac axis may occur in B-cell lineages. In malignant lymphomas, FilGAP expression was significantly higher in B-cell lymphomas than PTCL, and the immunohistochemical scores were positively correlated with cytoplasmic Rac1 scores in FL and DLBCL, but not in PTCL. Patients with FL and germinal center B-cell-like (GCB)-type DLBCL showing high FilGAP scores had poor overall survival rates as compared to the low-score patients. Moreover, multivariate Cox regression analysis showed that a high FilGAP score was a significant and independent unfavorable prognostic factor in FL, but not in DLBCL. In conclusion, FilGAP may contribute to change in cell motility of B-lymphocytes. In addition, its expression appears to be useful for predicting the behavior of B-cell lymphoma, in particular FL

    Intravenous rituximab is the standard of care in B-cell non-Hodgkin lymphoma, and is administered over 1·5-6 h. A subcutaneous formulation could reduce patients' treatment burden and improve resource utilisation in health care. We aimed to show the pharmacokinetic non-inferiority of subcutaneous rituximab to intravenous rituximab in follicular lymphoma and to provide efficacy and safety data. SABRINA is a two-stage, randomised, open-label phase 3 study at 113 centres in 30 countries. Eligible patients were aged 18 years or older and had histologically confirmed, previously untreated, CD20-positive grade 1, 2, or 3a follicular lymphoma; Eastern Co-operative Oncology Group performance statuses of 0-2; bidimensionally measurable disease (by CT or MRI); life expectancy of 6 months or more; adequate haematological function for 28 days or more; and one or more symptoms requiring treatment according to the Groupe d'Etudes des Lymphomes Folliculaires criteria. Patients were randomly assigned (1:1) by investigators or members of the research team via a dynamic randomisation algorithm to 375 mg/m 2 intravenous rituximab or 1400 mg subcutaneous rituximab, plus chemotherapy (six-to-eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone [CHOP] or eight cycles of cyclophosphamide, vincristine, and prednisone [CVP]), every 3 weeks during induction, then rituximab maintenance every 8 weeks. Randomisation was stratified by selected chemotherapy, Follicular Lymphoma International Prognostic Index, and region. The primary endpoint for stage 2 was overall response (ie, confirmed complete response, unconfirmed complete response, and partial response) at the end of induction. Efficacy analyses were done in the intention-to-treat population. Pooled data from stages 1 and 2 are reported on the basis of the clinical cutoff date of the last patient completing the maintenance phase of the study. This trial is registered with ClinicalTrials.gov, number NCT01200758; new

    We aimed to assess the prognostic significance of follicular lymphoma-associated macrophages in the era of rituximab treatment and maintenance. We applied immunohistochemistry for CD68 and CD163 to two large tissue microarrays (TMA). The first TMA included samples from 186 patients from the BC Cancer Agency (BCCA) who had been treated with first-line systemic treatment including rituximab, cyclophosphamide, vincristine, and prednisone. The second contained 395 samples from PRIMA trial patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, and randomized to rituximab maintenance or observation. Macrophage infiltration was assessed using Aperio image analysis. Each of the two cohorts was randomly split into training/validation sets. An increased CD163-positive pixel count was predictive of adverse outcome in the BCCA dataset [5-year progression-free survival (PFS) 38% vs. 72%, respectively, P = 0.004 in the training cohort and 5-year PFS 29% vs. 61%, respectively, P = 0.004 in the validation cohort]. In the PRIMA trial, an increased CD163 pixel count was associated with favorable outcome (5-year PFS 60% vs. 44%, respectively, P = 0.011 in the training cohort and 5-year PFS 55% vs. 37%, respectively, P = 0.030 in the validation cohort). CD163-positive macrophages predict outcome in follicular lymphoma, but their prognostic impact is highly dependent on treatment received. ©2015 American Association for Cancer Research.

    Full Text Available B-cell antigen receptor (BCR expression is indispensable for survival of most B-cell malignancies. In follicular lymphoma (FL, N-linked glycosylation sites are introduced in the immunoglobulin (Ig variable region genes. Oligosaccharides added to the acquired sites are unusually of the high-mannose type. These glycans interact with mannose-specific lectins, especially with dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN. Lectin binding to FL triggers persistent activating signals, suggesting that lectins within the tumor microenvironment promote cell survival and proliferation. Insertion of N-glycosylation sites in Ig variable region genes has been detected in other germinal center-associated lymphomas, specifically in subsets of diffuse large B-cell lymphomas and Burkitt’s lymphomas, suggesting involvement of altered glycans in pathogenesis of these malignancies as well. Furthermore, the BCR in chronic lymphocytic leukemia (CLL carries high-mannose oligosaccharides, albeit in the heavy chain constant rather than variable region. The high expression level of the unique glycoform, particularly in the more aggressive unmutated CLL subset, suggests a functional significance for this glycan in CLL. As lectin interaction with the BCR is critical for FL and probably for some other lymphomas, targeting this interaction is considered to be an interesting therapeutic strategy. Reagents for blockade of lectin–BCR interaction may include antibodies against high-mannose glycans and mannose-based oligosaccharide mimics or non-carbohydrate glycomimetics. Moreover, as this interaction triggers signaling pathways similar to those demonstrated for BCR engagement by antigen, BCR signal transduction inhibitors may emerge as effective therapeutics for lectin-driven malignancies.

    Follicular lymphoma (FL), except grade 3B, is characterized by the chromosomal translocation t(14;18)(q32;q21), which results in over-expression of the Bcl-2 protein. Ten per-cent of all FLs, however, do not show Bcl-2 protein expression with standard immunohistochemistry using a monoclonal Bcl-2

    Most follicular lymphomas (FLs) are genetically defined by the t(14;18)(q32;q21) translocation that juxtaposes the BCL2 gene to the immunoglobulin heavy chain (IgH) 3' regulatory regions (IgH-3'RRs). Despite this recurrent translocation, FL cases are heterogeneous in terms of intratumoral clonal diversity for acquired mutations and variations in the tumor microenvironment. Here we describe an additional mechanism that contributes to inter- and intratumoral heterogeneity in FLs. By applying a novel single-molecule RNA fluorescence-based in situ hybridization (FISH) technique to detect mRNA molecules of BCL2 and IgH in single cells, we found marked heterogeneity in the number of BCL2 mRNA transcripts within individual lymphoma cells. Moreover, BCL2 mRNA molecules correlated with IgH mRNA molecules in individual cells both in t(14;18) lymphoma cell lines and in patient samples. Consistently, a strong correlation between BCL2 and IgH protein levels was found in a series of 205 primary FL cases by flow cytometry and immunohistochemistry. Inter- and intratumoral heterogeneity of BCL2 expression determined resistance to drugs commonly used in FL treatment and affected overall survival of FL patients. These data demonstrate that BCL2 and IgH expressions are heterogeneous and coregulated in t(14;18)-translocated cells, and determine the response to therapy in FL patients

    Abdominal CT and subsequent lymphography were performed in 44 patients staged for malignant lymphoma (25 Hodgkin's disease, 19 Non-Hodgkin lymphoma). All patients had abdominal CT findings which were equivocal or not in agreement with clinical symptoms. In 79.5% of all patients (80% HL, 79% NHL) both examinations agreed if there was no lymph node involvement. There was disagreement in 5 patients with Hodgkin's disease and in 4 patients with Non-Hodgkin lymphoma. Most discrepancies consisted of a normal or equivocal CT in combination with an abnormal lymphogram. In 2 patients, CT was misinterpreted as showing involved lymph nodes whereas subsequent lymphography was normal. It is concluded that lymphography is indicated in the initial staging of malignant lymphomas as a complementary imaging technique, since the combination of the two methods yields improved diagnostic information.

    The cost-effectiveness analyses of follicular lymphoma (FL) treatments have focused on the second-line rituximab maintenance in patients with relapsed FL. The assessment of full FL treatment chain has been lacking. The aim of this study was to assess the cost-effectiveness of FL treatment sequences. Transitions between progression-free first-line treatment (PF1), progression-free second-line treatment (PF2), progression, and death health states were simulated with a probabilistic Markov model with half-cycle correction. At first, patients were assumed to be receiving rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP) induction. The first-line RCHOP induction responders continued without (RCHOP) or with (RCHOPR) the first-line rituximab-maintenance treatment. In the case of PF1 failure, patients received RCOPR/bendamustine or RCOPR/COP according to the European Society for Medical Oncology guidance. In the case of PF2 failure, patients were expected to receive the best supportive care (BSC). The survivals and adverse events were estimated with direct and indirect comparisons. Health outcomes and Finnish payer (drug, drug administration, monitoring, test, progression, serious adverse event) costs valued in 2010 euros were discounted with 3% per annum. The mean discounted lifetime overall survival with FL was 9.6 to 11.5 years, quality-adjusted survival was 7.2 to 8.8 quality-adjusted life-years (QALYs), progression-free time was 7.7 to 10.2 years, and costs were €153,425 to €168,549, depending on the treatment sequence. The incremental cost-effectiveness ratios for RCHOPR→RCOPR/bendamustine→BSC, RCHOPR→RCOPR/COP→BSC, and RCHOP→RCOPR/bendamustine→BSC were €9575/€8014/€5900, €9881/€8310/€6013, and €8812/€7194/€5808, respectively, per QALY/life-year/progression-free year gained in comparison with RCHOP→RCOPR/COP→BSC.

    To analyze the relationship of clinical variables related to prognosis and tumor burden, with metabolic variables obtained in the staging (18)F-FDG PET/CT, and their value in the prognosis in follicular lymphoma (FL). 82 patients with FL, a (18)F-FDG PET/CT at diagnosis and a follow-up for a minimum of 12 months, were retrospectively enrolled in the present study. Clinical variables (Tumor grade, Follicular Lymphoma International Prognostic Index (FLIPI) and Tumor burden) were evaluated. Metabolic variables such as SUVmax in the highest hypermetabolic lesion, extralymphatic locations, number of involved lymph node locations, bone marrow (BM) involvement, PET stage and diameter of the biggest hypermetabolic lesion, were analyzed in order to establish a PET score and classify the studies in low, intermediate and high metabolic risk. Clinical and metabolic variables (included metabolic risk) were compared. The relation among all variables and disease-free survival (DFS) was studied. The 28% of patients had a high-grade tumor. The 30.5% had FLIPI risk low, 29.3% intermediate y 40.2% high. The 42.7% presented a high tumor burden. The PET/CT was positive in 94% of patients. The tumor grade did not show significant relation with metabolic variable. FLIPI risk and tumor burden showed statistical relations with the SUV max and the PET score (p<0.008 and p=0.003 respectively). With respect to DFS, significant differences were detected for the PET stage and FLIPI risk (p=0.015 and p=0.047 respectively). FLIPI risk was the only significant predictor in Cox regression analysis, with a Hazard Ratio of 5.13 between high risk and low risk. The present research highlights the significant relation between metabolic variables obtained with FDG PET/CT and clinical variables although their goal as an independent factor of prognosis was not demonstrated in the present work.

Further to compare the usefulness of these tumor markers in differentiating diagnosis of the two common types of Non-Hodgkin's lymphoma (NHL. MATERIALS AND METHODS: Thirty-four consecutive pre-therapy adult patients with proven NHL (23 DLBCL and 11 FL underwent PET/CT and MRI examinations and laboratory tests. The maximum standardized uptake value (SUV(max, metabolic tumor volume (MTV, and metabolic tumor burden (MTB were determined from the PET/CT images. DWI was performed in addition to conventional MRI sequences using two b values (0 and 800 s/mm(2. The minimum and mean apparent diffusion coefficient (ADC(min and ADC(mean were measured on the parametric ADC maps. RESULTS: The SUV(max correlated inversely with the ADC(min (r =  -0.35, p<0.05. The ADC(min, ADC(mean, serum thymidine kinase (TK, Beta 2-microglobulin (B2m, lactate dehydrogenase (LD, and C-reactive protein (CRP correlated with both whole-body MTV and whole-body MTB (p<0.05 or 0.01. The SUV(max, TK, LD, and CRP were significantly higher in the DLBCL group than in the FL group. Receiver operating characteristic curve analysis showed that they were reasonable predictors in differentiating DLBCL from FL. CONCLUSIONS: The functional imaging markers determined from PET/CT and DWI are associated, and the SUV(max is superior to the ADC(min in differentiating DLBCL from FL. All the measured serum markers are associated with functional imaging markers. Serum LD, TK, and CRP are useful in differentiating DLBCL from FL.

    Full Text Available Christos EmmanouilidesDepartment of Medical Oncology, Interbalkan Hospital, Thessaloniki, GreeceAbstract: Several studies have indicated that radioimmunotherapy is an effective and clinically relevant complementary therapeutic approach for patients with B-cell non-Hodgkin’s lymphoma (NHL and may convert partial to complete response when given as consolidation after induction chemotherapy. Yttrium-90(90Y-ibritumomab tiuxetan (90Υ-ΙΤ, Zevalin®, Y2B8 has documented efficacy for both indolent and aggressive NHL. Patients considered eligible for 90Y-IT treatment should satisfy several screening criteria. A recently completed randomized study for patients with follicular lymphoma has demonstrated that 90Y-ibritumomab consolidation also produced a marked prolongation of the median time to progression from 13.5 to 37 months, while partial responders seem to derive relatively more benefit. Other published and ongoing studies explore a similar use for patients with aggressive lymphoma. Studies are comparing the use of 90Y-IT consolidation with the anti-CD20 antibody rituximab maintenance, which is also gaining acceptance. In conclusion, the documented benefit of radioimmunotherapy should be viewed in the context of the goals of treatment and the changing standards of care for lymphoma.

    Interferon alfa and cytotoxic drugs have synergistic effects in patients with non-Hodgkin's lymphoma. In 1986, we designed a clinical trial to evaluate the benefit of concomitant administration of recombinant interferon alfa with a regimen containing doxorubicin in patients with follicular non-Hodgkin's lymphoma. The trial involved 242 patients with advanced low-grade follicular non-Hodgkin's lymphoma selected on the basis of clinical, radiographic, and biologic criteria. All patients were treated with a regimen consisting of cyclophosphamide, doxorubicin, teniposide, and prednisone (CHVP), given monthly for six cycles and then every two months for one year. After randomization, 123 patients also received interferon alfa-2b at a dosage of 5 million units three times weekly for 18 months. The remaining 119 patients received chemotherapy alone. As compared with the patients treated with CHVP only, the patients treated with CHVP plus interferon alfa had a higher overall rate of response (85 percent vs. 69 percent, P = 0.006), a longer median event-free survival (34 months vs. 19 months, P < 0.001), and a higher rate of survival at 3 years (86 percent vs. 69 percent, P = 0.02). Granulocyte toxicity was greater in the patients treated with CHVP plus interferon alfa than in those treated with CHVP alone. There were no treatment-related deaths. Interferon alfa had to be stopped because of toxic effects (fatigue and hepatitis) in 13 patients (11 percent). The addition of interferon alfa to a regimen containing doxorubicin increased the rate of response, event-free survival, and overall survival in patients with advanced follicular non-Hodgkin's lymphoma, without serious toxicity, although some patients were unable to tolerate the side effects.

  4. High Throughput Sequencing Analysis of the Immunoglobulin Heavy Chain Gene from Flow-Sorted B Cell Sub-Populations Define the Dynamics of Follicular Lymphoma Clonal Evolution.

    Directory of Open Access Journals (Sweden)

    Emanuela Carlotti

    Full Text Available Understanding the dynamics of evolution of Follicular Lymphoma (FL clones during disease progression is important for monitoring and targeting this tumor effectively. Genetic profiling of serial FL biopsies and examples of FL transmission following bone marrow transplant suggest that this disease may evolve by divergent evolution from a common ancestor cell. However where this ancestor cell resides and how it evolves is still unclear. The analysis of the pattern of somatic hypermutation of the immunoglobulin gene (Ig is traditionally used for tracking the physiological clonal evolution of B cells within the germinal center and allows to discriminate those cells that have just entered the germinal center and display features of ancestor cells from those B cells that keep re-circulating across different lymphoid organs. Here we investigated the pattern of somatic hypermutation of the heavy chain of the immunoglobulin gene (IgH-VH in 4 flow-sorted B cells subpopulations belonging to different stages of differentiation, from sequential lymph node biopsies of cases displaying diverse patterns of evolution, using the GS-FLX Titanium sequencing platform. We observed an unexpectedly high level of clonality, with hundreds of distinct tumor subclones in the different subpopulations from the same sample, the majority detected at a frequency <10-2. By using a lineage trees analysis we observed in all our FL and t-FL cases that the oligoclonal FL population was trapped in a narrow intermediate stage of maturation that maintains the capacity to undergo SHM, but was unable to further differentiate. The presence of such a complex architecture highlights challenges currently encountered in finding a cure for this disease.

    To study the diagnostic value of BCL2 rearrangement in follicle center lymphoma (FCL) presenting as primary skin lesions, evaluate its prevalence and the prognostic value in primary cutaneous FCL (PCFCL), and assess prognostic factors in PCFCL. Fifty-three patients with a cutaneous presentation of FCL without a history of nodal lymphoma were selected retrospectively. Clinical and histologic data were collected together with staging and follow-up data. A fluorescence in situ hybridization (FISH) test for BCL2 split probes was performed on skin biopsy specimens. Initial staging procedures identified 47 PCFCLs and six cases of secondary skin involvement of FCL (SSIFCL). FISH detected seven cases carrying a BCL2 rearrangement: four (8.5%) of 47 PCFCLs and three (50%) of six SSIFCLs. These seven cases coexpressed BCL2 and CD10. In PCFCL, cutaneous relapse rate was 42.6%. A small/medium centrocytic cell population was associated with a higher probability of skin relapse in univariate (P = .008) and multivariate (P = .028) analysis, and BCL2 rearrangement detection was associated with secondary extracutaneous spreading (P = .05). We observed that BCL2 rearrangement in PCFCL is rare, associated with initial positivity of staging (diagnostic value) or with secondary extracutaneous spreading (prognostic value). In selected cases with BCL2-CD10 coexpression, FISH testing could detect patients with poor outcome and require closer monitoring. Copyright© by the American Society for Clinical Pathology.

    Follicular lymphoma (FL) results from the accumulation of malignant germinal center (GC) B cells leading to the development of an indolent and largely incurable disease. FL cells remain highly dependent on B-cell receptor (BCR) signaling and on a specific cell microenvironment, including T cells, macrophages, and stromal cells. Importantly, FL BCR is characterized by a selective pressure to retain surface immunoglobulin M (IgM) BCR despite an active class-switch recombination process, and by the introduction, in BCR variable regions, of N-glycosylation acceptor sites harboring unusual high-mannose oligosaccharides. However, the relevance of these 2 FL BCR features for lymphomagenesis remains unclear. In this study, we demonstrated that IgM(+) FL B cells activated a stronger BCR signaling network than IgG(+) FL B cells and normal GC B cells. BCR expression level and phosphatase activity could both contribute to such heterogeneity. Moreover, we underlined that a subset of IgM(+) FL samples, displaying highly mannosylated BCR, efficiently bound dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN), which could in turn trigger delayed but long-lasting BCR aggregation and activation. Interestingly, DC-SIGN was found within the FL cell niche in situ. Finally, M2 macrophages induced a DC-SIGN-dependent adhesion of highly mannosylated IgM(+) FL B cells and triggered BCR-associated kinase activation. Interestingly, pharmacologic BCR inhibitors abolished such crosstalk between macrophages and FL B cells. Altogether, our data support an important role for DC-SIGN-expressing infiltrating cells in the biology of FL and suggest that they could represent interesting therapeutic targets. © 2015 by The American Society of Hematology.

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of rituximab (RTX) [Roche] to submit evidence for the clinical and cost effectiveness of RTX as first-line maintenance treatment for patients with follicular non-Hodgkin's lymphoma (fNHL) whose disease has responded to induction therapy with RTX plus cytotoxic chemotherapy (R-CTX) in accordance with the Institute's Single Technology Appraisal (STA) process. The Liverpool Reviews and Implementation Group (LRiG) at the University of Liverpool was commissioned to act as the Evidence Review Group (ERG). This article summarizes the ERG's review of the evidence submitted by the manufacturer and provides a summary of the Appraisal Committee's (AC) decision. The clinical evidence was derived from a multi-centred, open-label, randomized phase III study (PRIMA) comparing first-line maintenance treatment with RTX with observation only in 1,018 patients with previously untreated advanced fNHL. Median time to event (MTE) for the primary endpoint of progression-free survival (PFS) in the RTX arm was not estimable due to data immaturity; median PFS in the observation arm was 48.36 months. A statistically significant benefit of RTX maintenance therapy for PFS was reported (hazard ratio [HR] 0.55, 95 % CI 0.44-0.68; p Markov methodology rather than patient simulations, the impact of patient age on the outcome and the projective PFS modelling. The ERG considered it impossible to draw firm conclusions regarding the clinical or cost effectiveness of the intervention as the dataset was as yet too immature. At a third meeting, the AC concluded that RTX could be recommended as first-line maintenance treatment for patients with fNHL whose disease has responded to induction R-CTX.

    Historically, the median overall survival for follicular lymphoma (FL) has been considered to be 9-10 years, and no treatment had ever prolonged this time period. Studies conducted more than 20 years ago demonstrated that treating patients with asymptomatic FL at the onset of the disease did not increase their survival, and that almost 20% of these patients did not need any treatment in the first 10 years of follow-up. Based on these facts, most clinical practice guidelines recommend active surveillance policies for patients with asymptomatic FL. The introduction of antiCD-20 monoclonal antibodies, over the last 15 years, has significantly increased the median survival rate to above 14 years. This improvement was achieved before the combination of rituximab and chemotherapy regimens became extensively used in patients with symptomatic disease. Therefore, this increase in survival may currently be more significant. At present, several clinical trials have evaluated low-toxicity therapies that prolong progression-free periods, among which rituximab monotherapy, radioimmunotherapy or the combination of rituximab with bendamustine are the most relevant. Unfortunately, these clinical trials have included only patients with symptomatic FL. The results of a recently reported clinical trial show that treatment with single-agent rituximab prolongs progression-free survival rates, time to new treatment and the quality of life of asymptomatic patients, as compared with the active surveillance strategy. Longer follow-up of these results and data regarding overall survival are awaited before this treatment can be recommended as the standard initial therapy. There are different therapeutic possibilities for asymptomatic FL patients, but no data are currently available to indicate which option is the best. Patients need to understand the risks and benefits of observation versus treatment before a final decision can be made. For patients who want active treatment the

    The purpose of this study was to evaluate prediction of prognosis after first-line radioimmunotherapy (RIT) of advanced follicular non-Hodgkin lymphoma (FL), by imaging with fluorine-18-fluorodeoxyglucose positron emission tomography with computed tomography ( 18 F-FDG-PET/CT) three months after induction treatment by Iodine-131-rituximab ( 131 I-rituximab). Objective response was determined using the Deauville 5-point scale in 68 prospective clinical trial patients. Baseline 18 F-FDG-PET/CT studies were used to calculate total-metabolic-tumor-volume (TMTV). Non-imaging studies included the Follicular lymphoma international prognostic index (FLIPI) and absolute baseline monocyte and lymphocyte counts. Patients were monitored for over ten years (median follow-up 59 months), and no patient was lost to follow-up. Complete response (CR) of 88% predicted excellent prognosis with median time-to-next-treatment (TTNT) not yet reached. Those patients (12%) who failed to achieve CR (Deauville ≤ 3) on 18 F-FDG-PET/CT at three months had significantly poorer outcomes ( p < 0.0001) with a median TTNT of 41 months. Requirement for re-treatment was predicted by FLIPI and absolute baseline monocyte count but not lymphocyte count. The TTNT was accurately predicted by 18 F-FDG-PET/CT Deauville response at three months following first-line therapy of FL with RIT. Early response demonstrated by imaging does, therefore, foretell prognosis in the individual FL patients.

    High-dose chemotherapy supported by autologous stem cell transplantation (HDT/ASCT) has contributed to modify the natural history of follicular lymphoma (FL); however, an overall survival (OS) benefit has been demonstrated at relapse only after a rituximab-free chemotherapy regimen. A total of 655 patients with FL were reported to the Spanish GELTAMO (Grupo Español de Linfomas y Trasplantes de Médula Ósea) registry and underwent first ASCT between 1989 and 2007. A total of 203 patients underwent ASCT in first complete response (CR1), 174 in second complete response (CR2), 28 in third complete response (CR3), 140 in first partial response (PR1), 81 in subsequent PR, and 29 with resistant/refractory disease; 184 patients received rituximab before ASCT. With a median follow-up of 12 years from ASCT, median progression-free survival (PFS) and overall survival (OS) were 9.7 and 21.3 years, respectively. Actuarial 12-year PFS and OS were 63% (95% confidence interval [CI], 58%-68%) and 73% (95% CI, 68%-78%), respectively, for patients in CR (with a plateau in the curve beyond 15.9 years), 25% (95% CI, 19%-28%) and 49% (95% CI 42%-56%), respectively, for patients in PR, and 23% (95% CI, 8%-48%) and 28% (95% CI, 9%-45%), respectively, for patients with resistant/refractory disease (P < .001). In patients who received rituximab before ASCT, the estimated 9-year PFS and OS from ASCT were 59.5% (95% CI, 51%-67%) and 75% (95% CI, 68%-83%), respectively. Interestingly, for patients who underwent transplantation in CR ≥2 or PR ≥2 who had received rituximab before ASCT (n = 90), 9-year PFS and OS were 61% (95% CI, 51%-73%) and 75% (95% CI, 65%-80%), respectively, with no relapses occurring beyond 5.1 years after ASCT. The cumulative incidence of second malignancies in the global series was 6.7% at 5 years and 12.8% at 10 years. This analysis strongly suggests that ASCT is a potentially curative option for eligible patients with FL. In the setting of relapse, it is

    The authors examined the "real-world" effectiveness of rituximab (R) maintenance therapy (R-maintenance) compared with observation after R-based induction therapy in patients with previously untreated follicular lymphoma (FL) in the United States. The National LymphoCare Study is a prospective, multicenter, observational study that enrolled > 2700 untreated patients with FL diagnosed from 2004 to 2007 at 265 sites in the United States. Among these, patients who achieved at least stable disease after R-based induction therapy were eligible for the current analysis. Patients who initiated R-maintenance within 215 days of completing induction therapy were categorized as the R-maintenance group, and those who did not initiate therapy during this period were categorized as the observation group. The objective of the current study was to determine the effect of R-maintenance on progression-free survival (PFS), time to next treatment (TTNT), and overall survival (OS). A total of 1439 patients completed R-based induction therapy, 1186 of whom met all inclusion criteria (541 patients received R-maintenance and 645 patients were observed). Characteristics that were found to be predictive of receiving R-maintenance were histology grade (1/2), Ann Arbor stage of disease (III/IV), geographic region (region other than the West), and practice setting (community practice). With a median follow-up of 5.7 years, R-maintenance was associated with superior PFS (hazards ratio [HR], 0.68; 95% confidence interval [95% CI], 0.56-0.84 [P = .0003]) and TTNT (HR, 0.66; 95% CI, 0.52-0.84 [P = .0007]). No significant difference in OS was observed (HR, 0.81; 95% CI, 0.58-1.14 [P = .23]). R-maintenance in patients with FL and at least stable disease after R-based induction therapy provided significantly longer PFS and TTNT in comparison with observation, but no significant difference in OS was observed with 5-years of follow-up. This comparative effectiveness study aligns with

The simultaneous occurrence of mixed-cellularity Hodgkin's lymphoma (HL and follicular non-Hodgkin's lymphoma (NHL was demonstrated in a 66-year-old man admitted in our Service with anaemia, hepatosplenomegaly and multiple abdominal lymph nodes. The morphological study of the spleen and lymph node of the splenic hilum showed an infiltrate composed of two distinct neoplasias. The liver was involved by NHL infiltrate and the peripancreatic lymph node exhibited HL. The Reed-Sternberg (RS cells expressed CD 15 and CD 30, whereas the NHL cells presented standard immunohistochemical features of follicular lymphoma. To our knowledge, this is the fifth case report of concurrent spleen involvement by composite lymphoma.

    A retrospective analysis of 140 patients with non-Hodgkin's lymphoma in clinical stage I or II classified according to a modified Lukes and Collins scheme was performed. Three major groups were found according to cell type, with different clinical features: (1) Small cell lymphomas with a relatively favourable survival in spite of high relapse rates. (2) Large cell lymphomas with lower relapse rates, but short time between relapse and death, and unfavourable survival. (3) Mixed small/large cleaved follicular centre cell lymphoma which was most favourable with respect to relapse and survival. Nodular lymphoma had the same overall relapse rate as diffuse lymphoma, but had a significantly longer survival. Tumours stage I were associated with significantly longer relapse-free survival and survival than stage II. The importance of separating the majority of non-Hodgkin's lymphomas into three main groups according to cell type is emphasized. These major groups require clinical approaches in terms of staging and treatment. (Auth.)

    Seventeen patients with stage IA non-Hodgkin's lymphoma of the Waldeyer's ring were treated with radiation therapy with or without chemotherapy. All lesions were judged as having intermediate grade malignancy in the Working Formulation. Eight patients received combined treatment with three cycles of cylcophosphamide, doxorubicin, vincristine and prednison (CHOP) and radiation therapy with 30 to 40 Gy. Another 9 patients were treated with radiation therapy 40 to 60 Gy alone. After a median follow-up of 69 months, all 8 patients, treated with combined modality were alive and relapse-free whereas 4 of the 9 treated with irradiation alone had relapsed. All relapses occurred transdiaphragmatically. Two of the 4 relapsing patients were saved, but the other two died of the disease. The 5-year relapse-free and cause-specific survival rates were 100% and 100% in the combined modality group, and 56% and 76% in the radiation therapy alone group (relapse-free: p=0.04, cause-specific: p=0.16). There were no serious complications related to treatment, although most patients complained of mouth dryness and most patients given CHOP had paresthesia. Our opinion was that the total impact of these two side-effects on quality of life was less pronounced after combined modality than after radiation therapy alone. Limited chemotherapy and radiation therapy seemed to be more beneficial than radiation therapy alone not only in relapse-free survival but also in quality of life after treatment. (orig.)

    Rationale: radioimmunotherapy (R.I.T.) with 90 Y-ibritumomab tiuxetan ([ 90 Y] Zevalin ) is a new treatment option for patients with relapsed/refractory non Hodgkin follicular lymphoma (F.L.). Efficacy increases when Zevalin is used earlier in the disease course. Currently, Zevalin dosage is based on weight and not dosimetry. This most likely results in a wide range of absorbed dose to critical organs and tumor, which in turn translates in unpredictable efficacy and toxicity. Optimizing R.I.T. with [ 90 Y] Zevalin will require its use as part of first-line therapy and implementation of patient-specific dosimetry methods in clinical trials. Objectives and methods: we have consecutively studied 2 new modalities of using Zevalin in first line therapy of F.L.. First, we conducted an international, randomized, phase 3 trial to evaluate the efficacy and safety of consolidation with Zevalin(15 MBq/Kg) in patients with advanced-stage F.L. achieving at least a partial response after induction immuno chemotherapy. A second approach consisted of evaluating a fractionated schedule with 2 doses of Zevalin (11.1 MBq/kg each), 9 to 13 weeks apart, as front line therapy in F.L. patients with high tumor burden. As part of this second approach, we designed a refined imaging-based (planar and 3-dimensional) dosimetry protocol to improve prediction of dose efficacy and toxicity after each dose of zevalin. Data acquisition was performed in 3 centers (Lille, Nantes and Manchester) while data treatment and specific dose calculations for major organ, tumor masses and bone marrow were centralized. Conclusion: Consolidation of first remission with 90 Y-ibritumomab tiuxetan in advanced-stage follicular lymphoma is highly effective with no unexpected toxicities, prolonging P.F.S. by 2 years and resulting in high P.R.-to-C.R. conversion rates regardless of type of first-line induction treatment. Preliminary data show the feasibility of front line fractionated R.I.T. with Zevalin in patient

    The final steps of oocyte capacitation and maturation are critical for embryonic development but detailed information is scarce on how the oocyte is affected during this period. In this study, 2033 oocytes were collected from 106 superovulated cattle at four different time points before ovulation....... Follicular characteristics were measured and oocyte quality was assessed by morphology, mRNA expression of eight marker genes or developmental ability after in vitro/in vivo maturation and subsequent in vitro fertilization and culture. Approaching ovulation, expected increases in follicular size and cumulus...... expansion suggested progression of oocyte maturation. No differences were found in the expression patterns of analyzed genes, except for heat-shock-protein (Hsp) that was lower in in vivo matured oocytes collected shortly before ovulation. Oocytes collected at this time also had higher developmental ability...

    CT is currently the mainstay in staging malignant lymphoma in children, but the risk of second neoplasms due to ionizing radiation associated with CT is not negligible. Whole-body MRI techniques and whole-body diffusion-weighted imaging (DWI) in particular, may be a good radiation-free alternative to CT. DWI is characterized by high sensitivity for the detection of lesions and allows quantitative assessment of diffusion that may aid in the evaluation of malignant lymphomas. This article will review whole-body MRI techniques for staging malignant lymphoma with emphasis on whole-body DWI. Furthermore, future considerations and challenges in whole-body DWI will be discussed. (orig.)

    Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma) is a B-cell tumor thought to originate from B-lymphocytes that are normally present in the marginal zone of lymphoid follicles of the lymphoid tissue. About 50% of MALT lymphoma occurs in gastrointestinal tract. The majority of patients present with localized disease and indolent clinical progression. In localized gastric MALT lymphoma with Helicobacter pylori (HP) infection, HP eradication is recommended as first line therapy. In those without HP infection and localized non-gastric MALT lymphoma, involved field radiation therapy(IFRT) is recommended as first line therapy. Patients in advanced stage and salvage setting are managed according to the recommendations for advanced follicular lymphoma. The long-term survival rate of MALT lymphoma patients is 80-90%.

    A retrospective analysis was done for 69 patients with Stage I and II non-Hodgkin lymphoma who were treated from May 1981 to December 1990, in the Department of Radiadtion Oncology, Korea University Hospital. We used Ann Arbor Staging system and Working Formulation for histological classification. Forty-three patients(43/69, 62.3%) were Stage I and 26 patients (26/69, 37.7%) were Stage II, and B symptom was found in 10.1%(7/69). Local control rate for all patients was 88.4%(61/69), with 80% (12/15) for nodal lymphoma and 90.7%(49/54) for extra nodal lymphoma. The total failure rate was 34.8%(24/69). Five of 24 (20.8%) patients who were failed developed local failure only, 12.5%(3/24) local failure with distant failure, and distant failure only were found in 66.7%(16/24). Between nodal lymphoma and extra nodal lymphoma, there was no significant survival difference, but extra nodal lymphoma showed higher incidence

    Full Text Available Background: Paraneoplastic pemphigus (PNP is an autoimmune mucocutaneous disease associated with cancer. Since the original description of the condition, various publications have suggested the presence of a heterogeneous spectrum of paraneoplastic mucocutaneous conditions with clinical features of lichenplanus. Several cases of PNP have been reported following treatment with fludarabine. Methods: We present a case of lichenoid syndrome in a follicular B-cell non-Hodgkin lymphoma (NHL patient after treatment with fludarabine and review 8 additional published cases of fludarabine related PNP. Results: Our case is unique due to the fact that the patient presented with lichenoid features both clinically and microscopically and responded well to rituximab therapy. According to literature, both skin and mucosa (eyes and gastrointestinal tract are involved and symptoms start about 1-2 weeks after exposure to fludarabine. Various immunosuppressive treatments have been employed including high dose steroids. Many of these patients developed complications related to the immunosuppressive therapy such as cytomegalovirus, candidiasis and pneumocystis carinii infection and died from respiratory failure. On the other hand, long-term remissions have also been described. Conclusion: Our case represents an unusual case of fludarabine related to mucocutaneous lichenoid syndrome, a variant of PNP, and in view of the outcome in previously described cases, rituximab may be considered a preferred and safe first line therapy for such complication.

    Follicular lymphoma (FL) is a disease of paradoxes-incurable but with a long natural history. We hypothesized that a combination of lymphokine-activated killer (LAK) cells and monoclonal antibodies might provide a robust synergistic treatment and tested this hypothesis in a phase II clinical trial (NCT01329354). In this trial, in addition to R-CHOP, we alternated the administration of only rituximab with rituximab and autologous LAK cells that were expanded ex vivo. Our objective was to determine the in vitro capability of LAK cells generated from FL patients to produce cytotoxicity against tumor cell lines and to determine rituximab- and obinutuzumab-induced cytotoxicity via antibody-dependent cellular cytotoxicity (ADCC) activity. We analyzed the LAK cell-induced cytotoxicity and rituximab (R)- and obinutuzumab (GA101)-induced ADCC activity. We show that LAK cells generated from FL patients induce cytotoxicity against tumor cell lines. R and GA101 enhance cytolysis through ADCC activity of LAK cells. Impaired LAK cell cytotoxicity and ADCC activity were detected in 50 % of patients. Percentage of NK cells in LAK infusions were correlated with the R- and GA101-induced ADCC. Our results indicate that the combination of R or GA101 and LAK cells should be an option as frontline maintenance therapy in patients with FL.

    An exploratory analysis of 75 follicular lymphoma patients treated with obinutuzumab or rituximab induction therapy (IT) for 4 weeks in the phase II GAUSS study aimed to determine whether positron emission tomography (PET) results could predict progression-free survival (PFS) and tumor response. The proportion of patients with a PFS event (progression or death) was higher in those who were PET-positive after IT (assessed using Deauville five-point scale criteria; 35/52, 67%) than PET-negative (5/20, 25%); the hazard ratio for progression or death was 0.25 (95%CI: 0.01-0.64; p = 0.0018). A significant association was also found when PET results were assessed using International Harmonization Project and European Organisation for Research and Treatment of Cancer criteria. Change between baseline and end of IT in values of standardized uptake value and other PET parameters were associated with PFS and response. Validation of these results in prospective studies of larger cohorts is warranted.

    Objective: To analyze the clinical features and prognosis of patients with stage I E /II E nongastric mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: Between 2000 and 2006, 40 patients with previously untreated nongrastric MALT lymphoma were retrospectively reviewed. The primary site of lymphoma was the intestinal tract in 10 patients, the orbit in 9, the thyroid in 8, the lung in 5, the Waldeyer ring in 2, and the others organs in 6. At diagnosis, 27 patients had stage I E , and 13 had stage II E disease. Seventeen patients were treated with radiotherapy with or without chemotherapy, 18 with chemotherapy without radiotherapy, and 5 with surgery alone. The median age was 54 years. The ratio of male to female was 2: 1. Results: With a median follow-up of 58 months, the estimated 5-year overall survival (OS) rate and progression-free survival (PFS) rate were 86% and 82%, respectively. The 5-year OS and PFS rates were 92% and 85% for stage I E , 76% and 82% for stage II E disease, respectively (χ 2 =3.66, P =0. 060; χ 2 =1.04, P=0. 300). The 5-year OS and PFS rates were both 100% for patients with MALT lymphoma of the orbit and ocular adnexa. None of the 17 patients with radiotherapy had locoregional relapse, whereas 3 of 23 (13%) patients without radiotherapy had locoregional relapse. Conclusions: Patients with stage I E nongastric MALT lymphoma have a favorable prognosis. Radiotherapy is still a standard care for early stage disease. The treatment outcome of patients with MALT lymphoma of the orbit and ocular adnexa is even better. (authors)

    Recent literature reports a potential association between high vitamin D and improved lymphoma prognosis. We evaluated the impact of pretreatment vitamin D on follicular lymphoma (FL) outcome. SWOG participants were previously untreated patients with FL enrolled onto SWOG clinical trials (S9800, S9911, or S0016) involving CHOP chemotherapy plus an anti-CD20 antibody (rituximab or iodine-131 tositumomab) between 1998 and 2008. Participants included in our second independent cohort were also previously untreated patients with FL enrolled onto the Lymphoma Study Association (LYSA) PRIMA trial of rituximab plus chemotherapy (randomly assigned to rituximab maintenance v observation) between 2004 and 2007. Using the gold-standard liquid chromatography-tandem mass spectrometry method, 25-hydroxyvitamin D was measured in stored baseline serum samples. The primary end point was progression-free survival (PFS). After a median follow-up of 5.4 years, the adjusted PFS and overall survival hazard ratios for the SWOG cohort were 1.97 (95% CI, 1.10 to 3.53) and 4.16 (95% CI, 1.66 to 10.44), respectively, for those who were vitamin D deficient (< 20 ng/mL; 15% of cohort). After a median follow-up of 6.6 years, the adjusted PFS and overall survival hazard ratios for the LYSA cohort were 1.50 (95% CI, 0.93 to 2.42) and 1.92 (95% CI, 0.72 to 5.13), respectively, for those who were vitamin D deficient (< 10 ng/mL; 25% of cohort). Although statistical significance was not reached in the LYSA cohort, the consistent estimates of association between low vitamin D levels and FL outcomes in two independent cohorts suggests that serum vitamin D might be the first potentially modifiable factor to be associated with FL survival. Further investigation is needed to determine the effects of vitamin D supplementation in this clinical setting. © 2015 by American Society of Clinical Oncology.

    Radiation therapy (RT) is one of the most effective agents available in the treatment of lymphomas. However, it is a local treatment, and today, with systemic treatments assuming a primary role for induction of response, RT is primarily used for consolidation. For advanced stage lymphomas...... treatment of larger and anatomically more challenging target volumes with much less radiation to normal tissues and consequently much lower risks of long-term complications. The modern concept of involved site radiation therapy (ISRT) has now been accepted as standard in lymphomas. In advanced Hodgkin...... type, the diffuse large B cell lymphoma (DLBCL). In patients treated with modern immunochemotherapy, RT to initial bulky disease or extralymphatic involvement is beneficial. For both HL and aggressive NHL, RT to residual masses after systemic treatment is of benefit. The role of PET in the evaluation...

    This guideline is a prerequisite for the quality management in the treatment of non-Hodgkin-lymphomas using radioimmunotherapy. It is based on an interdisciplinary consensus and contains background information and definitions as well as specified indications and detailed contraindications of treatment. Essential topics are the requirements for institutions performing the therapy. For instance, presence of an expert for medical physics, intense cooperation with all colleagues committed to treatment of lymphomas, and a certificate of instruction in radiochemical labelling and quality control are required. Furthermore, it is specified which patient data have to be available prior to performance of therapy and how the treatment has to be carried out technically. Here, quality control and documentation of labelling are of greatest importance. After treatment, clinical quality control is mandatory (work-up of therapy data and follow-up of patients). Essential elements of follow-up are specified in detail. The complete treatment inclusive after-care has to be realised in close cooperation with those colleagues (haematology-oncology) who propose, in general, radioimmunotherapy under consideration of the development of the disease.

    Fifteen patients with primary gastric malignant lymphoma who underwent radiotherapy were examined. Median age was 68 years, and male to female ratio was 1:2. All the cases were stage I including 7 cases of diffuse large B-cell lymphoma (DLBCL), 7 cases of MALT lymphoma, and 1 case of follicular lymphoma. Therapy methods were as follows. For DLBCL, 30 Gy of radiotherapy was performed after chemotherapy. For six cases of MALT lymphomas, 30 Gy of radiotherapy was performed. For one patient diagnosed as high-grade gastric MALT lymphoma was treated in the same way as DLBCL. For one patient with follicular lymphoma, 30 Gy of radiotherapy was performed. The radiotherapy was applied with 3-dimensional fixed multi-portal irradiation, with the reduced irradiation of the liver and kidney. There was no recurrence of disease in all cases, and all patients have been alive, and no-recurrence living periods are 20 to 120 months. There was no harmful adverse event, and the tumor had disappeared with 30 Gy of radiation therapy in all cases. Considering the occurrence of secondary cancer, it was considered that a dosage of more than 30 Gy was not necessary for primary gastric malignant lymphoma. (J.P.N.)

    Purpose: To assess the role of radiation therapy in the treatment of primary localized (Stage I: 24 cases and Stage II: 13 cases) non-Hodgkin's Lymphoma (NHL) of the oral cavity. Methods and Materials: In total, 37 patients (27 male, 10 female) with primary localized NHL of the oral cavity have been treated with radiotherapy alone (23 cases) or radiation with chemotherapy (14 cases). The age range was 29 to 86 years (median: 65). Clinical and treatment variables with potential prognostic significance for survival were evaluated by univariate and multivariate analysis. Of the 37 patients, 31 (84%) had intermediate-grade lymphomas and six (14%) had high-grade lymphomas. Four patients showed necrotic ulcer in the central portion of the hard palate. Results: The 5-year actuarial survival rate for all cases was 73%. The 5-year survival rates for intermediate-grade and high-grade lymphoma were 85% and 14%, respectively. Significant prognostic factors identified by the multivariate analysis were histologic grade of malignancy (p = 0.02) and central necrotic ulcer in the tumor (p = 0.02). Chemotherapy did not improve survival (p = 0.41). Conclusions: Our analysis suggests that radiotherapy alone may be approved as the treatment for localized oral NHL with no ulceration and intermediate histology. However, patients with high-grade lymphoma and/or necrotic ulcer are difficult to cure with radiation alone and aggressive treatment should be advocated to improve survival

    Overall survival (OS) is the gold-standard end point for studies evaluating autologous stem cell transplantation (ASCT) in follicular lymphoma (FL), but assessment may be elusive due to the lengthy disease course. We analyzed the validity of two earlier end points, proposed in the setting of first-line chemo-/immunotherapy, as surrogates for OS-progression-free survival (PFS) status at 24 months (PFS24) and complete response at 30 months (CR30) post-ASCT. We also have investigated the clinical features of patients with early progression after ASCT. Data were available for 626 chemosensitive FL patients who received ASCT between 1989 and 2007. Median follow-up was 12.2 years from ASCT. In the PFS24 analysis, 153 (24%) patients progressed within 24 months and 447 were alive and progression-free at 24 months post-ASCT (26 who died without disease progressions within 24 months were excluded). Early progression was associated with shorter OS (hazard ratio [HR], 6.8; P = 0.00001). In the subgroup of patients who received an ASCT in the setting or relapse after being exposed to rituximab, the HR was 11.3 (95% CI, 3.9-30.2; P < 0.00001). In the CR30 analysis, 183 of 596 (31%) response-evaluable patients progressed/died with 30 months post-ASCT. The absence of CR30 was associated with shorter OS (HR, 7.8; P < 0.00001), including in patients with prior rituximab (HR, 8.2). PFS24 and CR30 post-ASCT are associated with poor outcomes and should be primary end points. Further research is needed to identify this population to be offered alternative treatments. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Purpose In low–tumor burden follicular lymphoma (FL), maintenance rituximab (MR) has been shown to improve progression-free survival when compared with observation. It is not known whether MR provides superior long-term disease control compared with re-treatment rituximab (RR) administered on an as-needed basis. E4402 (RESORT) was a randomized clinical trial designed to compare MR against RR. Patients and Methods Eligible patients with previously untreated low–tumor burden FL received four doses of rituximab, and responding patients were randomly assigned to either RR or MR. Patients receiving RR were eligible for re-treatment at each disease progression until treatment failure. Patients assigned to MR received a single dose of rituximab every 3 months until treatment failure. The primary end point was time to treatment failure. Secondary end points included time to first cytotoxic therapy, toxicity, and health-related quality of life (HRQOL). Results A total of 289 patients were randomly assigned to RR or MR. With a median follow-up of 4.5 years, the estimated median time to treatment failure was 3.9 years for patients receiving RR and 4.3 years for those receiving MR (P = .54). Three-year freedom from cytotoxic therapy was 84% for those receiving RR and 95% for those receiving MR (P = .03). The median number of rituximab doses was four patients receiving RR and 18 for those receiving MR. There was no difference in HRQOL. Grade 3 to 4 toxicities were infrequent in both arms. Conclusion In low–tumor burden FL, a re-treatment strategy uses less rituximab while providing disease control comparable to that achieved with a maintenance strategy. PMID:25154829

    The diagnostic criteria for follicular lymphoma (FL) transformation vary among the largest series, which commonly exclude histologically-documented transformation (HT) mandatorily. The aims of this retrospective observational multicentre study by the Spanish Grupo Español de Linfoma y Transplante Autólogo de Médula Ósea, which recruited 1734 patients (800 males/934 females; median age 59 years), diagnosed with FL grades 1-3A, were, (i) the cumulative incidence of HT (CI-HT); (ii) risk factors associated with HT; and (iii) the role of treatment and response on survival following transformation (SFT). With a median follow-up of 6·2 years, 106 patients developed HT. Ten-year CI-HT was 8%. Considering these 106 patients who developed HT, median time to transformation was 2·5 years. High-risk FL International Prognostic Index [Hazard ratio (HR) 2·6, 95% confidence interval (CI): 1·5-4·5] and non-response to first-line therapy (HR 2·9, 95% CI: 1·3-6·8) were associated with HT. Seventy out of the 106 patients died (5-year SFT, 26%). Response to HT first-line therapy (HR 5·3, 95% CI: 2·4-12·0), autologous stem cell transplantation (HR 3·9, 95% CI: 1·5-10·1), and revised International Prognostic Index (HR 2·2, 95% CI: 1·1-4·2) were significantly associated with SFT. Response to treatment and HT were the variables most significantly associated with survival in the rituximab era. Better therapies are needed to improve response. Inclusion of HT in clinical trials with new agents is mandatory. © 2017 John Wiley & Sons Ltd.

    Purpose: Early-stage Hodgkin lymphoma (HL) is a rare disease, and the location of lymphoma varies considerably between patients. Here, we evaluate the variability of radiation therapy (RT) plans among 5 International Lymphoma Radiation Oncology Group (ILROG) centers with regard to beam arrangements, planning parameters, and estimated doses to the critical organs at risk (OARs). Methods: Ten patients with stage I-II classic HL with masses of different sizes and locations were selected. On the basis of the clinical information, 5 ILROG centers were asked to create RT plans to a prescribed dose of 30.6 Gy. A postchemotherapy computed tomography scan with precontoured clinical target volume (CTV) and OARs was provided for each patient. The treatment technique and planning methods were chosen according to each center's best practice in 2013. Results: Seven patients had mediastinal disease, 2 had axillary disease, and 1 had disease in the neck only. The median age at diagnosis was 34 years (range, 21-74 years), and 5 patients were male. Of the resulting 50 treatment plans, 15 were planned with volumetric modulated arc therapy (1-4 arcs), 16 with intensity modulated RT (3-9 fields), and 19 with 3-dimensional conformal RT (2-4 fields). The variations in CTV-to-planning target volume margins (5-15 mm), maximum tolerated dose (31.4-40 Gy), and plan conformity (conformity index 0-3.6) were significant. However, estimated doses to OARs were comparable between centers for each patient. Conclusions: RT planning for HL is challenging because of the heterogeneity in size and location of disease and, additionally, to the variation in choice of treatment techniques and field arrangements. Adopting ILROG guidelines and implementing universal dose objectives could further standardize treatment techniques and contribute to lowering the dose to the surrounding OARs.

    The cure rate of early stage Hodgkin's lymphoma (HL) is excellent; investigating the late effects of treatment is thus important. Esophageal toxicity is a known side effect in patients receiving radiotherapy (RT) to the mediastinum, although little is known of this in HL survivors. This study...... investigates the dose to the esophagus in the treatment of early stage HL using different RT techniques. Estimated risks of early esophagitis, esophageal stricture and cancer are compared between treatments....

  2. Does Radiation Have a Role in Advanced Stage Hodgkin's or Non-Hodgkin Lymphoma?

    Radiation therapy (RT) is one of the most effective agents available in the treatment of lymphomas. However, it is a local treatment, and today, with systemic treatments assuming a primary role for induction of response, RT is primarily used for consolidation. For advanced stage lymphomas, the indications for the use of RT have been questioned and debated, and proper randomized evidence is sparse. RT has significant long-term side effects, and the very extended RT fields of the past yielded unacceptable toxicity in many patients. Modern advanced imaging and conformal RT techniques now enable treatment of larger and anatomically more challenging target volumes with much less radiation to normal tissues and consequently much lower risks of long-term complications. The modern concept of involved site radiation therapy (ISRT) has now been accepted as standard in lymphomas. In advanced Hodgkin lymphoma (HL), RT to residual disease and/or initial bulk benefits some patients, depending on the chemotherapy regimen used. The more intensive the chemotherapy regimen, the fewer patients benefit from RT. In advanced aggressive non-Hodgkin lymphoma (NHL), most of the evidence comes from the most common type, the diffuse large B cell lymphoma (DLBCL). In patients treated with modern immunochemotherapy, RT to initial bulky disease or extralymphatic involvement is beneficial. For both HL and aggressive NHL, RT to residual masses after systemic treatment is of benefit. The role of PET in the evaluation and indication for RT to residual masses has not been tested in randomized trials. In advanced indolent NHL, very low dose RT offers excellent palliation with very few side effects. Modern RT in advanced lymphomas warrants further evaluation in randomized trials.

    Full Text Available For two libraries (PDF1 and ODF1 using Illumina sequencing 44,082,301 and 43,708,132 clean reads were obtained, respectively. After being mapped to the bovine RefSeq database, 15,533 genes were identified to be expressed in both types of follicles (cut-off RPKM > 0.5, of which 719 were highly expressed in bovine follicles (cut-off RPKM > 100. Furthermore, 83 genes were identified as being differentially expressed in ODF1 versus PDF1, where 42 genes were upregulated and 41 genes were downregulated. KEGG pathway analysis revealed two upregulated genes in ODF1 versus PDF1, CYP11A1, and CYP19A1, which are important genes in the steroid hormone biosynthesis pathway. This study represents the first investigation of transcriptome of bovine follicles at predeviation and onset of deviation stages and provides a foundation for future investigation of the regulatory mechanisms involved in follicular development in cattle.

    Full Text Available Follicular mucinosis is an uncommon inflammatory disorder that characteristically presents as follicular papules and/or indurated plaques. The face, neck, and scalp are the most frequently affected sites, although lesions may occur on any site of the body. Histologically, the disorder is characterized by mucin deposition in the follicular epithelium. The condition is frequently divided into primary and secondary forms, with the latter form frequently associated with mycosis fungoides. In this case report, we describe a child with follicular mucinosis of the back and trunk and discuss the clinical variants, histopathological pattern, and treatment options.

    The presence of a bulky tumour at staging on CT is an independent prognostic factor in malignant lymphomas. However, its prognostic value is limited in diffuse disease. Total metabolic tumour volume (TMTV) determined on 18 F-FDG PET/CT could give a better evaluation of the total tumour burden and may help patient stratification. Different methods of TMTV measurement established in phantoms simulating lymphoma tumours were investigated and validated in 40 patients with Hodgkin lymphoma and diffuse large B-cell lymphoma. Data were processed by two nuclear medicine physicians in Reggio Emilia and Creteil. Nineteen phantoms filled with 18 F-saline were scanned; these comprised spherical or irregular volumes from 0.5 to 650 cm 3 with tumour-to-background ratios from 1.65 to 40. Volumes were measured with different SUVmax thresholds. In patients, TMTV was measured on PET at staging by two methods: volumes of individual lesions were measured using a fixed 41 % SUVmax threshold (TMTV 41 ) and a variable visually adjusted SUVmax threshold (TMTV var ). In phantoms, the 41 % threshold gave the best concordance between measured and actual volumes. Interobserver agreement was almost perfect. In patients, the agreement between the reviewers for TMTV 41 measurement was substantial (ρ c = 0.986, CI 0.97 - 0.99) and the difference between the means was not significant (212 ± 218 cm 3 for Creteil vs. 206 ± 219 cm 3 for Reggio Emilia, P = 0.65). By contrast the agreement was poor for TMTV var . There was a significant direct correlation between TMTV 41 and normalized LDH (r = 0.652, CI 0.42 - 0.8, P 41 , but high TMTV 41 could be found in patients with stage 1/2 or nonbulky tumour. Measurement of baseline TMTV in lymphoma using a fixed 41% SUVmax threshold is reproducible and correlates with the other parameters for tumour mass evaluation. It should be evaluated in prospective studies. (orig.)

    To evaluate the prognostic utility of the American Joint Committee on Cancer (AJCC) staging system for ocular adnexal lymphoma (OAL).
 A multicenter, consecutive case series of patients with biopsy-proven conjunctival, orbit, eyelid, or lacrimal gland/sac lymphoma was performed. The electronic pathology and clinical records were reviewed for new or recurrent cases of ocular adnexal lymphoma. The main outcome measures included pathology and clinical staging (AJCC and Ann Arbor systems), treatment, and recurrence (local and systemic). Statistical analysis included demographic evaluations and the Kaplan-Meier survival probability method.
 Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue were the most common (n=60/83, 72%). The most common Ann Arbor clinical stages were IE (76%) followed by IIE (17%) and IIIE (7%). Pathology identified 13 cases (15%) that were upstaged to group IV (p=0.017). Similarly, AJCC clinical stages were cT1NOMO (21.7%), cT2NOMO (44.6%), cT3N0M0 (5%), and cT4NOMO (2.4%). Local control was achieved in 75% of treated patients. There were 19 local recurrences from which 14 (74%) belonged to the non-radiation treatment groups. Lower-risk groups (T1 and T2 without lymph node involvement or metastatic disease of AJCC and IE of Ann Arbor) had longer disease-free survival than the higher-risk groups (AJCC T1, T2 with nodal involvement or metastatic disease, T3, and T4 as well as Ann Arbor II, III, and IV). The overall mean follow-up was 43.3 months (range 6-274).
 Regardless of stage, recurrence and disease-free survival were more closely related to treatment and histopathology rather than tumor size or site-specific location.

    We explored the addition of rituximab to high-dose cytarabine (ara-C), oxaliplatin (L-OHP), and dexamethasone [R-DHAOx], in resistant and relapsed patients with CD20-positive follicular non-Hodgkin's lymphoma. Twenty-two patients were included; they were treated previously with one to five chemotherapy regimens, including 13 patients who had also received rituximab. R-DHAOx consisted of rituximab, 375mg/m(2), day 1; dexamethasone, 40mg/d, days one to four; L-OHP, 130mg/m(2), day 1; and ara-C, 2000mg/m(2) every 12 h, day 2. Courses were repeated every 21 days for eight courses. Twenty-one patients (95%) achieved a complete response and one had a partial response. Responses were obtained in patients with and without resistance to prior treatment, either alone or combined with rituximab. The median follow-up time was 58.3 months (range, 8.7-92.6 months). Progression-free survival reached a plateau at 84% at 38.2 months. Only two of the 21 complete responders have relapsed. Tumor molecular markers disappeared in all 10 complete responders whose markers were found before treatment. Peripheral neuropathy related to the cumulative dose of L-OHP, and myelosuppression were the most prominent toxic effects. R-DHAOx is highly active for salvage treatment of patients with follicular non-Hodgkin's lymphoma, and it produces long-term antitumor efficacy. 2009 Elsevier Masson SAS. All rights reserved.

    Full Text Available Abstract Background This retrospective analysis is focused on the efficacy and safety of radioimmunotherapy (RIT with Zevalin® in nine patients with recurrent follicular lymphoma (FL who were treated in a consolidation setting after having achieved complete remission or partial remission with FCR. Methods The median age was 63 yrs (range 46-77, all patients were relapsed with histologically confirmed CD20-positive (grade 1 or 2 FL, at relapse they received FCR every 28 days: F (25 mg/m2x 3 days, C (1 gr/m2 day 1 and R (375 mg/m2 day 4 for 4 cycles. Who achieved at least a partial remission, with 90Yttrium Ibritumomab Tiuxetan 11.1 or 14.8 MBq/Kg up to a maximum dose 1184 MBq, at 3 months after the completion of FCR. The patients underwent a further restaging at 12 weeks after 90Y-RIT with total body CT scan, FDG-PET/CT and bilateral bone marrow biopsy. Results Nine patients have completed the treatment: FCR followed by 90Y-RIT (6 patients at 14.8 MBq/Kg, 3 patients at 11.1 MBq/Kg. After FCR 7 patients obtained CR and 2 PR; after 90Y-RIT two patients in PR converted to CR 12 weeks later. With median follow up of 34 months (range 13-50 the current analysis has shown that overall survival (OS is 89% at 2 years, 76% at 3 years and 61% at 4 years. The most common grade 3 or 4 adverse events were hematologic, one patient developed herpes zoster infection after 8 months following valacyclovir discontinuation; another patient developed fungal infection. Conclusions Our experience indicate feasibility, tolerability and efficacy of FCR regimen followed by 90Y-RIT in patients relapsed with grades 1 and 2 FL with no unexpected toxicities. A longer follow up and a larger number of patients with relapsed grades 1 and 2 FL are required to determine the impact of this regimen on long-term duration of response and PFS.

  11. The management of patients with limited-stage classical Hodgkin lymphoma.

    2006-01-01

    The term limited-stage Hodgkin lymphoma refers to those patients with stage I-II disease and an absence of bulky disease. Among those patients with classical Hodgkin lymphoma, approximately one-third of patients will fall into this category. As long-term disease control can now be anticipated in more than 90% of these patients, management strategies must increasingly address the need to reduce the long-term treatment-related risks. Current treatment options include use of combined modality therapy that includes an abbreviated course of chemotherapy and involved-field radiation or treatment with chemotherapy, currently consisting of ABVD, as a single modality. The choice of treatment between these two options involves specific trade-offs that must balance issues of disease control against long-term risk of late effects.

  13. Evaluation of a Fast Protocol for Staging Lymphoma Patients with Integrated PET/MRI.

    Directory of Open Access Journals (Sweden)

    Johannes Grueneisen

    Full Text Available The aim of this study was to assess the applicability of a fast MR-protocol for whole-body staging of lymphoma patients using an integrated PET/MR system.A total of 48 consecutive lymphoma patients underwent 52 clinically indicated PET/CT and subsequent PET/MRI examinations with the use of 18F-FDG. For PET/MR imaging, a fast whole-body MR-protocol was implemented. A radiologist and a nuclear medicine physician interpreted MRI and PET/MRI datasets in consensus and were instructed to identify manifestations of lymphoma on a site-specific analysis. The accuracy for the identification of active lymphoma disease was calculated and the tumor stage for each examination was determined. Furthermore, radiation doses derived from administered tracer activities and CT protocol parameters were estimated and the mean scan duration of PET/CT and PET/MR imaging was determined. Statistical analysis was performed to compare the diagnostic performance of PET/MRI and MRI alone. The results of PET/CT imaging, all available histopathological samples as well as results of prior examinations and follow-up imaging were used for the determination of the reference standard.Active lymphoma disease was present in 28/52 examinations. PET/MRI revealed higher values of diagnostic accuracy for the identification of active lymphoma disease in those 52 examinations in comparison to MRI, however, results of the two ratings did not differ significantly. On a site specific analysis, PET/MRI showed a significantly higher accuracy for the identification of nodal manifestation of lymphoma (p<0.05 if compared to MRI, whereas ratings for extranodal regions did not reveal a significant difference. In addition, PET/MRI enabled correct identification of lymphoma stage in a higher percentage of patients than MRI (94% vs. 83%. Furthermore, SUVs derived from PET/MRI were significantly higher than in PET/CT, however, there was a strong positive correlation between SUVmax and SUVmean of the two

    Purpose: The aim of this study was to evaluate the efficacy of radiation therapy (RT) for early-stage mucosa-associated lymphoid tissue (MALT) lymphoma. Materials and methods: Patients with stage ΙE (n = 48) and stage ΠE (n = 2) MALT lymphoma treated with RT were reviewed. The primary tumor originated in the stomach in 20 patients, in the orbit in 9 patients, in the conjunctiva or eyelid and the parotid glands in 6 patients each, and 9 patients in the others. The median total RT dose was 32 Gy (range, 25.6-50 Gy). The median follow-up time was 50 months. Results: Although disease did not recur in the RT field in any patient regardless of the total dose, disease recurred outside the RT field in the seven patients. As all recurrences were localized, salvage RT was performed for each recurrence and achieved complete response without recurrence in the field. The 5-year overall survival, local control, and progression-free survival rates were 96.6%, 100%, and 82.2%, respectively. Conclusions: A total dose of 25-30 Gy is appropriate for local control of MALT lymphoma. RT is also an effective salvage therapy in cases of localized recurrence

    The results of treatment in 175 consecutive patients with non-Hodgkin lymphoma (NHL) clinical stage I treated between 1969 and 1984 were analysed according to different pretreatment prognostic variables. Treatment consisted of radiotherapy in 166 of the 175 patients. The estimated 5 and 10-year disease-free survival rates (DFS) were 63% and 60% and the survival rates at 5 and 10 years 82% and 76% respectively. Lymphomas arising from gut-associated lymphoid tissue, i.e. Waldeyer's ring, the thyroid and the gastrointestinal tract had a more favourable clinical course (10-year projected DFS 83%) than nodal (50%) and other extranodal lymphomas. Although the number of patients with other extranodal sites was small, sites such as testis, nasal cavity, paranasal sinus and extradural space seemed to have a high relapse rate. Unfavourable clinical courses were also observed among nodal high-grade NHL if the lymph nodes were larger than 5 cm in diameter. Chemotherapy before radiotherapy may be recommended in NHL subgroups with a high relapse rate and which today are potentially curable with chemotherapy, i.e. high-grade NHL. This study indicates that large nodal lymphomas and some extranodal sites belong to this group. (orig.)

    The treatment of Hodgkin's lymphoma has improved dramatically over the past decades. Over the last half century, Hodgkin's lymphoma has become one of the most curable cancers of adulthood. More than 90% of the patients with localized stages of the disease can be cured with modern treatment strategies. Long-term toxicities are now the major concern for survivors of early-stage disease. Contemporary therapeutic approaches for Hodgkin's lymphoma attempt to preserve the high cure rate achieved, while reducing treatment-related acute and late toxicities. The aim of this review is to re-examine the historical and the current role of radiotherapy for early-stage Hodgkin's lymphoma, given the latest evidence of an increasing role of chemotherapy for the treatment of this malignancy. The literature search was performed in PubMed Plus. Studies on children were excluded

    The presence of a bulky tumour at staging on CT is an independent prognostic factor in malignant lymphomas. However, its prognostic value is limited in diffuse disease. Total metabolic tumour volume (TMTV) determined on {sup 18}F-FDG PET/CT could give a better evaluation of the total tumour burden and may help patient stratification. Different methods of TMTV measurement established in phantoms simulating lymphoma tumours were investigated and validated in 40 patients with Hodgkin lymphoma and diffuse large B-cell lymphoma. Data were processed by two nuclear medicine physicians in Reggio Emilia and Creteil. Nineteen phantoms filled with {sup 18}F-saline were scanned; these comprised spherical or irregular volumes from 0.5 to 650 cm{sup 3} with tumour-to-background ratios from 1.65 to 40. Volumes were measured with different SUVmax thresholds. In patients, TMTV was measured on PET at staging by two methods: volumes of individual lesions were measured using a fixed 41 % SUVmax threshold (TMTV{sub 41}) and a variable visually adjusted SUVmax threshold (TMTV{sub var}). In phantoms, the 41 % threshold gave the best concordance between measured and actual volumes. Interobserver agreement was almost perfect. In patients, the agreement between the reviewers for TMTV{sub 41} measurement was substantial (ρ {sub c} = 0.986, CI 0.97 - 0.99) and the difference between the means was not significant (212 ± 218 cm{sup 3} for Creteil vs. 206 ± 219 cm{sup 3} for Reggio Emilia, P = 0.65). By contrast the agreement was poor for TMTV{sub var}. There was a significant direct correlation between TMTV{sub 41} and normalized LDH (r = 0.652, CI 0.42 - 0.8, P <0.001). Higher disease stages and bulky tumour were associated with higher TMTV{sub 41}, but high TMTV{sub 41} could be found in patients with stage 1/2 or nonbulky tumour. Measurement of baseline TMTV in lymphoma using a fixed 41% SUVmax threshold is reproducible and correlates with the other parameters for tumour mass evaluation

    Full Text Available Background:   Primary bone lymphoma or non-Hodgkin lymphoma of bone is a rare disease. There are only a few case series of stage IE of this condition in medical literature. The aim of this study is to determine the rate of survival   for stage IE after combined modality treatment, the rate of local recurrence, and the results of limb salvage in cases   of local recurrence.     Methods:   We collected data from 61 patients with histologically confirmed PBL treated at the Musculoskeletal   Oncology Department of our hospital from 2000 to 2010. Retrospective evaluation included demographics, symptoms, tumor locations, outcomes of surgical treatment for local recurrence and survival rates. Results:   All patients received Combined Modality Therapy. Overall,five year survival was 89% and five year disease free survival rate was 78%. Local recurrence occurred in 6 patients during follow up period, which was treated surgically     by wide excision and reconstruction. The mean follow-up for the local recurrence group was 36(24-54 months and mortality rate in this group was 17%. Conclusions:   Combined Modality Therapy for stage IE primary bone lymphomaresults in good survival rate. In case   of local recurrence, wide excision and reconstruction improves the outcomes.

    Full Text Available Radiation therapy has a key role in the combined modality treatment of early-stage Hodgkin’s Lymphoma (HL. Nevertheless, late toxicity still remains an issue. A modern approach in HL radiotherapy includes lower doses and smaller fields, together with the implementation of sophisticated and dedicated delivery techniques. Aim of the present review is to discuss the current role of radiotherapy and its potential future developments, with a focus on major clinical trials, technological advances and their repercussion in the clinical management of HL patients.

    Purpose: Mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct disease with specific clinical and pathologic features that may affect diverse organs. We analyzed our recent experience with Stage I/II MALT lymphoma presenting in the stomach and other organs to assess the outcome following involved field radiation therapy (RT). Patients and Methods: Seventy patients with Stage IE (62) and IIE (8) disease were treated between 1989 and 1998. Patients with transformed MALT were excluded. The median age was 62 years (range, 24-83 years), M:F ratio 1:2.2. Presenting sites included stomach, 15; orbital adnexa, 19; salivary glands, 15; thyroid, 8; lung, 5; upper airways, 3 (nasopharynx, 2; larynx, 1); urinary bladder, 3; breast, 1; and rectum, 1. Staging included site-specific imaging, CT abdomen in 66 patients (94%) and bone marrow biopsy in 54 (77%). Sixty-two patients received radiation therapy: 52 received RT alone, 7 received chemotherapy and RT, and 3 received antibiotics followed by RT. Median RT dose was 30 Gy (range, 17.5-35 Gy). Most frequently used RT prescriptions were 25 Gy (26 patients--18 orbit, 6 stomach, and 2 salivary glands), 30 Gy (23 patients), and 35 Gy (8 patients). Five patients had complete surgical excision of lymphoma and no other treatment (stomach 1, salivary 2, lung 2), whereas 2 patients with gastric lymphoma received antibiotics only. One patient refused treatment and was excluded from the analysis of treatment outcome, leaving 69 patients with a median follow-up of 4.2 years (range, 0.3-11.4 years). Results: A complete response was achieved in 66/69 patients, and 3 patients had partial response (2 lung, 1 orbit). The 5-year disease-free survival (DFS) was 76%, and the overall survival was 96%. No relapses were observed in patients with stomach and thyroid lymphoma. The 5-year DFS for these patients was 93%, in contrast to 69% for patients presenting in other sites (p 0.006). Among the 5 patients treated with surgery only, 2

    From 1966 to 1985, 103 patients with a localized follicular lymphoma were treated at the Fondation Bergonie. Clinical staging was performed using, after physical examination, chest X-rays, bipedal lymphangiography and unilateral bone marrow biopsy (BMB). The patients were then treated by radiotherapy with or without chemotherapy. Overall survival (OS) at 5 and 10 years is 69 and 56.3%, respectively. Relapse-free survival (RFS) is 53.7 and 49%. Unifactorial analysis shows three prognostic parameters to be independently significant in terms of OS: age, stage and B symptons. In terms of RFS, only 2 factors are significant: age and B symptons. Multivariate analysis (Cox model) shows that age is a more important prognostic factor than stage. 40 refs.; 3 figs.; 3 tabs

    The efficacy and safety of cyclophosphamide, vincristine, and prednisone (CVP) followed by tositumomab and iodine-131 ((131)I) -tositumomab therapy were evaluated in a multicenter phase II study in patients with untreated low-grade follicular lymphoma. Patients received six cycles of CVP followed by one cycle of tositumomab and (131)I-tositumomab (one dosimetric dose and one therapeutic dose). The treatment was evaluated for efficacy and safety. All 30 patients enrolled completed CVP as well as tositumomab and (131)I-tositumomab therapy. The overall response rate after completion of therapy was 100%, with 28 patients (93%) achieving a complete response (CR) and two patients achieving a partial response. Of the 17 patients with bone marrow involvement at enrollment, 15 achieved a confirmed CR. Fourteen of 15 patients with bulky disease (> or = 5 cm) had a CR after treatment completion. After a median follow-up of 8.4 years, the median response duration had not been reached (range, 3 to 111+ months). Five-year progression-free and overall survival rates were 56% and 83%, respectively. The most common grade > or = 3 hematologic adverse events were neutropenia (87%) and thrombocytopenia (37%). Nineteen patients received growth factor support, and three required blood product transfusions. No patients developed human antimurine antibodies. Two patients developed myelodysplastic syndrome/acute myeloid leukemia. These mature data demonstrate that sequential therapy with a non-anthracycline-containing regimen comprising CVP followed by one cycle of tositumomab and (131)I-tositumomab produced high response rates with adequate safety and durable remissions and that this regimen represents a highly active treatment for first-line therapy of follicular non-Hodgkin's lymphoma.

    The purpose of this study was to assess the usefulness of three-station black-blood fast short-inversion time inversion recovery (STIR) imaging in detecting and staging malignant lymphoma. Seventeen patients with malignant lymphoma were examined with a 1.5T imager. The findings and stagings determined with three-station black-blood fast STIR imaging were compared with reference standards (e.g., computed tomography [CT] findings and clinical stagings). Three-station black-blood fast STIR imaging provided a fat-suppressed T2-weighted imaging contrast with fewer flow artifacts and revealed nodal involvement as well as bone marrow and spleen involvement to an extent comparable with CT. Especially notable was the excellent specificity (94%) of this imaging technique. Regarding disease staging, significant agreement was observed between clinical staging (k=0.60) and staging as evaluated by three-station black-blood fast STIR, although the detection of lymphadenopathy in the thorax was relatively poor. The average time required for this imaging was approximately 30 min. Three-station black-blood fast STIR MR imaging may be useful as a staging tool for malignant lymphoma because this imaging technique reveals lymphoma lesions, which determine the staging, without radiation exposure or the use of contrast agents.

    In earlier studies, involvement of the small intestine was reported in patients with gastrointestinal lymphoma. Prospective data on the involvement of the small intestine in patients suffering from gastric extranodal MZBCL of MALT do not exist so far. In this study, we investigated the frequency of the involvement of the small intestine and the role of capsule endoscopy in patients with gastrointestinal extranodal MZBCL of MALT and of follicular lymphoma. 40 consecutive patients with gastrointestinal extranodal MZBCL of MALT (26 men, 14 women, aged 27 - 80 years), and 7 patients with known follicular lymphoma of the small intestine (5 men, 2 women, aged 34 - 63 years) underwent capsule endoscopy. Involvement of the small intestine was identified by capsule endoscopy in all 7 patients with known follicular lymphoma of the small intestine. In 6 of 40 patients with gastric extranodal MZBCL of MALT abnormal findings could be observed, three of these findings indicative for lymphoma involvement of the small intestine. However, in each of these 3 cases, intestinal involvement had been already diagnosed by conventional GI endoscopy before capsule endoscopy. Capsule endoscopy is able to detect involvement of the small intestine in patients with gastrointestinal lymphoma. However, involvement of the small intestine seems to be rare in patients with gastric extranodal MZBCL of MALT. In summary, routine diagnostic work-up of the small intestine, e. g. by capsule endoscopy seems unnecessary because of the rare involvement of the small intestine and an excellent long-term outcome irrespective of a possible intestinal manifestation. © Georg Thieme Verlag KG Stuttgart · New York.

    The stage of disease in patients with malignant lymphoma in important in decision of treatment modality and in prediction of prognosis. The authors evaluated the usefulness of PET with F18-FDG in initial staging, in reevaluation after radical therapy and in diagnosis of recurrence or disease progression of malignant lymphoma, compared with conventional imaging studies. The efficacy of positron emission tomography (PET) with fluorine-18-fluorodeoxyglucose (F18-FDG) was evaluated in several tumors. In malignant lymphoma. It was reported that the concentration of FDG was increased in tumor tissues, and that PET with F18-FDG was more sensitive and specific in staging evaluation compared with CT scan. The visual analysis of FDG-PET would be helpful in initial staging work-up, in reevaluation of residual disease after radical therapy and in suspicious recurrence or disease progression, determining the residual disease of lymphoma after radical therapy. But more studies with larger number of cases and longer follow-up were required. The results of this study can be bases for the direction of future studies for the usefulness of PET in malignant lymphoma

    Full Text Available In malignant lymphomas, cell kinetics has shown to be related with histologic type as well as with the clinical behaviour. The aim of our study was to investigate the relevance of cell proliferation parameters on overall survival in non‐Hodgkin's lymphomas as well as their relationship with prognostic factors such as International Prognostic Index (IPI. We performed DNA‐flow‐cytometry (S‐phase fraction and detection of DNA‐aneuploidy as well as cytologic examination and the AgNOR technique in material obtained by fine needle aspiration of lymph nodes at diagnosis. The majority of the patients were stage IV by Ann Arbor and intermediate risk by IPI (42/55. When analyzing all patients together, histologic type by the WHO classification, IPI and the presence of a DNA‐aneuploid clone could not separate well patients with a different survival. For all patients, univariate Cox analysis revealed S‐phase (SPF and AgNOR parameters to be of prognostic value. In the multivariate analysis, however, only SPF remained in the final model. Yet, when stratifying for DNA‐ploidy, only the total number of AgNORs/nucleus was an independent parameter. Looking only at the DNA‐diploid cases, the AgNOR pattern remained the most important parameter, whereas for the DNA‐aneuploid cases this was true for SPF. When studying patients with B large cell lymphoma separately, only DNA‐ploidy was a prognostic factor. In summary, cell kinetic parameters reveal important prognostic information in NHL patients. Furthermore, DNA‐aneuploidy seems to interfere with the analysis of the AgNOR pattern.

    Full Text Available Advanced-stage primary cutaneous T-cell lymphoma has an unfavorable prognosis and low survival rates. Aggressive treatment with chemotherapy is not curative and causes considerable side effects. The combination of bexarotene and denileukin diftitox is associated with an acceptable safety profile and a likely synergistic effect because bexarotene is capable of modulating expression of IL-2 receptor and enhance the susceptibility of T-cell leukemia cells to denileukin diftitox. In the case reported here, the response to this combined treatment was satisfactory and well tolerated. The patient showed a complete regression of pruritus, restlessness, and insomnia. Skin lesions improved partially, and lymphadenopathy was reduced and finally disappeared completely.

    To evaluate whether template-based structured reports (SRs) add clinical value to primary CT staging in patients with diffuse large B-cell lymphoma (DLBCL) compared to free-text reports (FTRs). In this two-centre study SRs and FTRs were acquired for 16 CT examinations. Thirty-two reports were independently scored by four haematologists using a questionnaire addressing completeness of information, structure, guidance for patient management and overall quality. The questionnaire included yes-no, 10-point Likert scale and 5-point scale questions. Altogether 128 completed questionnaires were evaluated. Non-parametric Wilcoxon signed-rank test and McNemar's test were used for statistical analysis. SRs contained information on affected organs more often than FTRs (95 % vs. 66 %). More SRs commented on extranodal involvement (91 % vs. 62 %). Sufficient information for Ann-Arbor classification was included in more SRs (89 % vs. 64 %). Information extraction was quicker from SRs (median rating on 10-point Likert scale=9 vs. 6; 7-10 vs. 4-8 interquartile range). SRs had better comprehensibility (9 vs. 7; 8-10 vs. 5-8). Contribution of SRs to clinical decision-making was higher (9 vs. 6; 6-10 vs. 3-8). SRs were of higher quality (p < 0.001). All haematologists preferred SRs over FTRs. Structured reporting of CT examinations for primary staging in patients with DLBCL adds clinical value compared to FTRs by increasing completeness of reports, facilitating information extraction and improving patient management. • Structured reporting in CT helps clinicians to assess patients with lymphoma. • This two-centre study showed that structured reporting improves information content and extraction. • Patient management may be improved by structured reporting. • Clinicians preferred structured reports over free-text reports.

    Purpose: The involved node radiation therapy (INRT) strategy was introduced for patients with Hodgkin lymphoma (HL) to reduce the risk of late effects. With INRT, only the originally involved lymph nodes are irradiated. We present treatment outcome in a retrospective analysis using this strategy in a cohort of 97 clinical stage I-II HL patients. Methods and Materials: Patients were staged with positron emission tomography/computed tomography scans, treated with adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy, and given INRT (prechemotherapy involved nodes to 30 Gy, residual masses to 36 Gy). Patients attended regular follow-up visits until 5 years after therapy. Results: The 4-year freedom from disease progression was 96.4% (95% confidence interval: 92.4%-100.4%), median follow-up of 50 months (range: 4-71 months). Three relapses occurred: 2 within the previous radiation field, and 1 in a previously uninvolved region. The 4-year overall survival was 94% (95% confidence interval: 88.8%-99.1%), median follow-up of 58 months (range: 4-91 months). Early radiation therapy toxicity was limited to grade 1 (23.4%) and grade 2 (13.8%). During follow-up, 8 patients died, none from HL, 7 malignancies were diagnosed, and 5 patients developed heart disease. Conclusions: INRT offers excellent tumor control and represents an effective alternative to more extended radiation therapy in the combined modality treatment for early-stage HL.

    The aim of the study was to investigate the DNA polymorphic genotype in MMP-2 promoter gene as a potential candidate region for the development of the cutaneous T-cell lymphoma (CTCL) and/or its progression. A total of 89 Czech patients with CTCL (including 23 patients with large plaque parapsoriasis) were compared to 198 controls of similar age and sex distribution, without personal or family history of chronic skin diseases and without personal history of malignancy. The three selected polymorphisms in the promoter of MMP-2 gene (-1575G/A, -1306C/T, and -790T/G) were determined using the PCR-based methodology with RFLP. In our cohort, the associated GGCCTT MMP-2 promoter genotype was highly significantly more frequent in CTCL-Ia stage patients compared to patients with parapsoriasis, the tests having high sensitivity and specificity (78%, 83%, resp.). To conclude, use of associated MMP-2 promoter genotype as a DNA marker might make it possible to distinguish between the patients with parapsoriasis and those with CTCL stage Ia, which could substantially improve possibilities of clinical diagnostics, therapy design, and prognosis of this serious condition in the early stages.

    Follicular thyroid carcinoma (FTC) is considered as a disease of the elderly with a higher incidence in females as compared to papillary thyroid carcinoma (PTC). Some studies have reported its occurrence at an early age, which may be attributed to early diagnosis because of the availability of advanced techniques. The prognosis of the disease is considered poor as compared to that of PTC. The conclusions drawn in this review are based on 663 cases in whom adequate data was available for meaningful analysis followed for a mean period of 9.2 years, median, 7.8 years; range, 1-32 years

    Full Text Available Objective The clinical, imaging and pathological manifestations of one patient at different stages of primary central nervous system lymphoma (PCNSL have been analyzed to disclose its pathogenesis. Methods and Results A 29-year-old female patient showed recurrent onsets. On the first onset, the main clinical manifestation was blurred vision and visual field defect. Cranial MRI showed a patchy lesion in the right parietal and occipital lobes without obvious occupying sign. T1WI showed slight low-intensity sign, T2WI and FLAIR showed high-intensity signs. Enhanced scanning showed heterogeneous punctate enhancement. The lesion disappeared gradually after glucocorticoid impact therapy. Headache, vomiting and left limb paralysis were the main clinical manifestations on the second onset, and MRI showed a lesion in the right frontal and parietal lobes with obvious occupying sign and solid enhancement, low-intensity on T1WI, high-intensity on T2WI and FLAIR. The tumor was totally removed under microscope. Histological findings showed large tumor cells, rich cytoplasm, nuclei with various sizes and shapes, conspicuous mitosis, patchy necrosis, and interstitial small vessel hyperplasia. Immunohistochemical staining showed that membrane of tumor cells was positive for CD20, and nuclei were positive for paired box gene 5 (PAX5 and multiple myeloma oncogene 1 (MUM1. In a few tumor cells, membrane was positive for CD10 and CD30, and nuclei were positive for cyclin D1. Besides, tumor cells were negative for CD3, anaplastic lymphoma kinase (ALK and glial fibrillary acidic protein (GFAP. Ki?67 labeling index was about 80%. EBER in situ hybridization (ISH assay showed that mRNA coded by Epstein?Barr (EB virus was negative. The tumor showed angiotropic characteristics, and the walls of involved blood vessels were wrapped and destructed. The final diagnosis was confirmed as diffuse large B cell lymphoma. Conclusions PCNSL has various imaging features, revealing as

    To compare the efficacy of chemotherapy alone, radiotherapy alone and combined-modality therapy in the treatment for early-stage Hodgkin's lymphoma (HL). From 1999 to 2002, totally 150 patients with stage I or II HL were treated in our hospital. They were stratified into several groups based on initial treatment strategy: chemotherapy alone (CT group, n = 22), radiotherapy alone (RT group, n = 18), combined-modality therapy (CMT group, n = 109) and surgical resection (SR group, n = 1). Chemotherapy regimens were mainly ABVD (adriamycin, bleomycin, vinblastine and dacarbazine) and MOPP (mechlorethamine, vincristine, procarbazine and prednisone). Radiotherapy modes included involved field radiotherapy (IFRT), extended field radiotherapy (EFRT) and sub-total nodal irradiation (STNI). The pathological types included nodular sclerosis (NS, n = 84), mixed-cellularity (MC, n = 39), lymphocyte-predominant (LP, n = 23), lymphocyte-depleted (LD, n = 3) and nodular lymphocyte predominant Hodgkin's disease (NLPHD, n = 1). Of those, 72 were evaluble in terms of prognostic factors. No poor prognostic factor was found in 36.1% or 29.2% of the patients according to EORTC or GHSG criteria, respectively. There were 33 patients with complete response (CR), 109 with partial response (PR), 5 with stable disease (SD) and 3 with progressive disease (PD) after initial therapy. The median follow-up period was 71.5 months. The overall 7-yr survival rate was 89.3%, and treatment failure rate at 6 years was 18.8%. The response rate of CMT group was superior to that of CT group, and the patients with nodular sclerosis or mixed-cellularity type had significantly lower risk of treatment failure (P = 0.009 and 0.019, respectively). The multivariate analysis revealed that the treatment strategies affected the prognosis significantly. The risk of failure of chemotherapy alone was 2.52 times higher than that of combined-modality therapy (P = 0.004). No predictive factor affecting OS was identified

    Recent trials show that > 90% of patients with early stage Hodgkin`s Lymphoma (ESHL) can be cured, especially when using the ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapeutic (CT) protocol. The use of radiotherapy (RT) is variable and can be selected according to the presence of specific risk factors, including PET-CT, as recently reported. To report the experience in the treatment of ESHL. Retrospective and descriptive analysis of patients with ESHL treated at the Red de Salud UC-Christus between 2011-2015. Twenty-two patients were treated. In 73%, the tumor was of nodular sclerosis histologic type. Most patients (95%) were in stage II, and 78% had a favorable prognosis according to the Deutsche Hodgkin Studiengruppe (GHSG) criteria. All patients were stratified using PET-CT and treated using the ABVD CT protocol, for 4-6 cycles. Only 5 patients received RT. There was no change of conduct after interim-PET-CT results. Ninety one percent of patients achieved complete response and there were two cases of refractory disease. Both cases underwent hematopoietic stem cell transplantation. After 17 months of median follow-up, 91% of patients are relapse-free, and only one patient died (5%). ABVD offers excellent results for ESHL patients. The benefit of PET-CT should be evaluated with prospective protocols, aiming to select patients needing RT or to reduce the number of CT cycles.

    Eradication of Helicobacter pylori leads to cure of gastric mucosa-associated lymphoid tissue (MALT) lymphoma in 75% of localized cases. However, prolonged follow-up is necessary to determine whether a lymphoma responds to therapy. In a small series of cases, we showed that t(11;18)(q21;q21)-positive MALT lymphomas failed to respond to H. pylori eradication. The present study aimed to verify this finding in a large cohort and confirm whether the translocation predicts the response of stage I(E) tumors, for which clinical staging has little prognostic value. A total of 111 patients with H. pylori-positive gastric MALT lymphoma treated with antibiotics were studied. Clinical staging was undertaken before therapy. The response of lymphoma to H. pylori eradication was determined by histologic examination of gastric biopsy specimens. Diagnostic biopsy specimens were analyzed for t(11;18)(q21;q21) by reverse-transcription polymerase chain reaction of the API2-MALT1 transcript. Forty-seven of the 48 patients who showed complete regression had lymphoma at stage I(E), whereas 43 of the 63 nonresponsive cases were at stage I(E) and the remaining cases at stage II(E) or above. t(11;18)(q21;q21) was detected in 2 of 48 complete-regression cases, and these positive cases showed relapse of lymphoma in the absence of H. pylori reinfection. In contrast, the translocation was present in 42 of the 63 nonresponsive cases, including 26 of 43 (60%) at stage I(E). t(11;18)(q21;q21)-positive gastric MALT lymphomas, including those at stage I(E), do not respond to H. pylori eradication. Detection of the translocation should help the clinical management of patients with gastric MALT lymphoma.

    To document subtype-specific clinical features of lymphoma of the eyelid, and their effect on patient outcome. Retrospective observational case series. Patient data were collected from 7 international eye cancer centers from January 1, 1980 through December 31, 2015. The cases included primary and secondary lymphomas affecting the eyelid. Overall survival, disease-specific survival (DSS), and progression-free survival were the primary endpoints. Eighty-six patients were included. Mean age was 63 years and 47 (55%) were male. Non-Hodgkin B-cell lymphomas constituted 83% (n = 71) and T-cell lymphomas constituted 17% (n = 15). The most common subtypes were extranodal marginal-zone lymphoma (EMZL) (37% [n = 32]), follicular lymphoma (FL) (23% [n = 20]), diffuse large B-cell lymphoma (DLBCL) (10% [n = 9]), mantle cell lymphoma (MCL) (8% [n = 7]), and mycosis fungoides (MF) (9% [n = 8]). EMZL had a female predilection (69% [22 of 32]), whereas MCL (71% [5 of 7]) and MF (88% [7 of 8]) had a male predominance. MCL (57% [4 of 7]), DLBCL (56% [5 of 9]), and MF (88% [7 of 8]) were frequently secondary lymphomas. Localized EMZL and FL were mostly treated with external beam radiation therapy, whereas DLBCL, MCL, and high Ann Arbor stage EMZL and FL were frequently treated with chemotherapy. DLBCL and MCL had a poor prognosis (5-year DSS, 21% and 50%, respectively), whereas EMZL, FL, and MF had a good prognosis (5-year DSS, 88%, 88% and 86%, respectively). Lymphoma of the eyelid consists mainly of the lymphoma subtypes EMZL, FL, DLBCL, MCL, and MF. High-grade DLBCL and MCL, as well as MF, are frequently secondary eyelid lymphomas. The main predictor of outcome was the histologic subtype: EMZL, FL, and MF had a significantly better prognosis than MCL and DLBCL. Copyright © 2017 Elsevier Inc. All rights reserved.

    Purpose: The German Hodgkin Study Group (GHSG) trial HD11 established 4 cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and 30 Gy of radiation therapy (RT) as a standard for early stage (I, II), unfavorable Hodgkin lymphoma (HL). Additional cycles of ABVD may allow for a reduction in RT dose and improved toxicity profile. Methods and Materials: Patients treated with combined modality therapy at the Duke Cancer Institute for early stage, unfavorable HL by GHSG criteria from 1994 to 2012 were included. Patients who did not undergo post-chemotherapy functional imaging (positron emission tomography or gallium imaging) or who failed to achieve a complete response were excluded. Clinical outcomes were estimated using the Kaplan-Meier method. Late effects were also evaluated. Results: A total of 90 patients met inclusion criteria for analysis. Median follow-up was 5 years. Chemotherapy consisted primarily of ABVD (88%) with a median number of 6 cycles. The median dose of consolidation RT was 23.4 Gy. Four patients had relapses, 2 of which were in-field. Ten-year progression-free survival (PFS) and overall survival (OS) were 93% (95% confidence interval [CI]: 0.82-0.97) and 98% (95% CI: 0.92-0.99), respectively. For the subset of patients (n=46) who received 5 to 6 cycles of chemotherapy and ≤24 Gy, the 10-year PFS and OS values were 88% (95% CI: 70%-96%) and 98% (95% CI: 85% - 99%), respectively. The most common late effect was hypothyroidism (20%) with no cardiac complications. Seven secondary malignancies were diagnosed, with only 1 arising within the RT field. Conclusions: Lower doses of RT may be sufficient when combined with more than 4 cycles of ABVD for early stage, unfavorable HL and may result in a more favorable toxicity profile than 4 cycles of ABVD and 30 Gy of RT.

    In newly diagnosed patients with Hodgkin disease and non-Hodgkin lymphoma, the value of computed tomography (CT) of the liver was assessed as regards impact on the staging process. 201 patients at two medical centers had pretreatment abdominal CT within two weeks of liver biopsy. CT sensitivity, specificity and accuracy in both groups were determined and sensitivity in both groups was very low (8%). If liver biopsy results had been omitted, reliance on CT and other clinical staging procedures alone would have led to important staging errors in 18 of these 201 patients (9%) - overstaging would have occurred twice and understaging 16 times. In 7 additional patients, the lack of demonstration by CT of documented liver disease was without clinical consequence because disseminated extranodal lymphoma was visible at other sites or at extrahepatic regions of the same CT scan. In patients with newly diagnosed Hodgkin disease and non-Hodgkin lymphoma, CT is an unreliable indicator of liver status and cannot replace liver biopsy in supplying the data required for optimal management.

    Composite lymphomas consist of 2 or more distinct lymphomas occurring in a single anatomical site or simultaneously in different sites and can be composed of any combination of B-cell non-Hodgkin lymphoma (NHL), T-cell NHL, or Hodgkin lymphoma (HL). Cases of composite lymphomas with more than 2 lymphomas are extremely rare, with only 4 reports in the literature. We report the case of a 49-year-old man with a triple composite lymphoma in a single lymph node, consisting of small lymphocytic lymphoma, follicular lymphoma, and mantle cell lymphoma in situ. The patient received multiple courses of chemotherapy and an autologous stem cell transplant, which resulted in complete remission. Then, 6 years after the stem cell transplant, he developed classical HL. This unique case is, to our knowledge, the first report of a patient with triple composite lymphoma consisting of 3 small mature B-cell NHLs, who subsequently developed a fourth lymphoma.

    Introduction: The cure rate of early stage Hodgkin's lymphoma (HL) is excellent; investigating the late effects of treatment is thus important. Esophageal toxicity is a known side effect in patients receiving radiotherapy (RT) to the mediastinum, although little is known of this in HL survivors. This study investigates the dose to the esophagus in the treatment of early stage HL using different RT techniques. Estimated risks of early esophagitis, esophageal stricture and cancer are compared between treatments. Material and methods: We included 46 patients {>=}15 years with supra diaphragmatic, clinical stage I-II HL, who received chemotherapy followed by involved node RT (INRT) to 30.6 Gy at our institution. INRT was planned with three-dimensional conformal RT (3DCRT). For each patient a volumetric modulated arc therapy (VMAT), proton therapy (PT) and mantle field (MF) treatment plan was simulated. Mean, maximum and minimum dose to the esophagus were extracted from the treatment plans. Risk estimates were based on dose-response models from clinical series with long-term follow-up. Statistical analyses were performed with repeated measures ANOVA using Bonferroni corrections. Results: Mean dose to the esophagus was 16.4, 16.4, 14.7 and 34.2 Gy (p < 0.001) with 3DCRT, VMAT, PT and MF treatment, respectively. No differences were seen in the estimated risk of developing esophagitis, stricture or cancer with 3DCRT compared to VMAT (p = 1.000, p = 1.000, p = 0.356). PT performed significantly better with the lowest risk estimates on all parameters compared to the photon treatments, except compared to 3DCRT for stricture (p = 0.066). On all parameters the modern techniques were superior to MF treatment (p < 0.001). Conclusions: The estimated dose to the esophagus and the corresponding estimated risks of esophageal complications are decreased significantly with highly conformal RT compared to MF treatment. The number of patients presenting with late esophageal side

    Objectives: Patients with lymphoma are at higher-risk of secondary malignancies mainly due to effects of cancer therapy as well as frequent radiological surveillance. We thus aimed to investigate the objective and subjective image quality as well as radiation exposure and risk of full-dose standard (FDS), full-dose iterative (FDI), and half-dose iterative (HDI) image reconstruction in patients with lymphoma. Material and methods: In 100 lymphoma patients, contrast-enhanced whole-body staging was performed on a dual-source CT. To acquire full-dose and half-dose CT data simultaneously, the total current-time product was equally distributed on both tubes operating at 120 kV. HDI reconstructions were calculated by using only data from one tube. Quantitative image quality was assessed by measuring image noise in different tissues of the neck, thorax, and abdomen. Overall diagnostic image quality was assessed using a 5-point Likert scale. Radiation doses and risks were estimated for a male and female reference person. Results: For all anatomical regions apart from the lungs image noise was significantly lower and the overall subjective image quality significantly better when using FDI and HDI instead of FDS reconstruction (p < 0.05). For the half-dose protocol, the risk to develop a radiation-induced cancer was estimated to be less than 0.11/0.19% for an adult male/female. Conclusions: Image quality of FDI and more importantly of HDI is superior to FDS reconstruction, thus enabling to halve radiation dose and risk to lymphoma patients.

    Purpose: To evaluate the effect of radiotherapy on the severe pulmonary toxicity observed in the pilot study of BAGCOPP (bleomycin, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone, and gemcitabine) for advanced-stage Hodgkin's lymphoma. Methods and Materials: Patients with Stage III or IV Hodgkin's lymphoma or Stage IIB with risk factors participated in this single-arm, multicenter pilot study. Results: Twenty-seven patients were enrolled on the study before its premature closure as a result of the development of serious pulmonary toxicity in 8 patients. The pulmonary toxicity occurred either during or immediately after the BAGCOPP chemotherapy course. Pulmonary toxicity contributed to one early fatality but resolved in the other 7 patients after cessation of gemcitabine and bleomycin, allowing continuation of therapy. Fifteen patients received consolidative radiotherapy, including 4 who previously had pulmonary toxicity. There were no reported cases of radiation pneumonitis and no exacerbation of pulmonary symptoms in the 4 patients who had had previous pulmonary toxicity. Conclusions: The severe pulmonary toxicity observed in this study has been attributed to an interaction between gemcitabine and bleomycin. Gemcitabine (when administered without bleomycin) remains of interest in Hodgkin's lymphoma and is being incorporated into a new German Hodgkin's Lymphoma Study Group protocol that also includes consolidative radiotherapy. This study supports the concept of the integration of radiotherapy in gemcitabine-containing regimens in Hodgkin's lymphoma if there is an interval of at least 4 weeks between the two modalities and with a schedule whereby radiotherapy follows the chemotherapy

    Purpose : Traditionally the patients with early stage non-Hodgkin's lymphoma of he head and neck was treated with radiotherapy. But the results were not satisfactory due to distant relapse. Although combined treatment with radiotherapy and chemotherapy was tried with some improved results and chemotherapy alone was also tried in recent years, the choice of treatment for the patients with early stage non-Hodgkin's lymphoma of the head and neck has not been defined. Therefore, in order to determine the optimum treatment method, we analysed retrospectively the outcomes of the patients with Ann Arbor stage I and II non-Hodgkin's lymphoma localized to the head and neck who were treated at Severance Hospital. Materials and Methods : 159 patients with stage I and II non-Hodgkin's lymphoma localized to the head and neck were treated at our hospital from January, 1979 to December, 1992. Of these patients, 114 patients whose primary sites were Waldeyer's ring or nodal region, and received prescribed radiation dose and/or more than 2 cycles of chemotherapy, were selected to analyze the outcomes according to the treatment methods (radiotherapy alone, chemotherapy alone, and combined treatment with radiotherapy and chemotherapy). Results : Five year overall actuarial survival of the patients whose primary site was Waldeyer's ring was 62.5%, and that of the patients whose primary site was nodal region was 53.8%. There was no statistically significant difference between survivals of both groups. Initial response rate to radiotherapy, chemotherapy, and combined treatment was 92%, 83%, 94% respectively, and 5 year relapse free survival was 49.9%, 52.4%, 58.5% respectively (statistically no significant). In the patients with stage I, 3 year relapse free survival of chemotherapy alone group was 75% and superior to other treatment groups. In the patients with stage II, combined treatment group revealed the best result with 60.1% of 3 year relapse free survival. The effect of

    Objective: With the optimal therapy remains unclear for nasal NK/T cell lymphoma, the aim of this study is to analyze the outcome of radiotherapy as primary treatment for localized stage I E and II E diseases. Methods: Between January. 1983 and December 2003, 105 patients with stage I E and II E primary nasal NK/T cell lymphoma were retrospectively reviewed. According to the Ann Arbor Staging System, there were 83 stage I E and 22 stage II E. Stage I E was subdivided into limited stage I E confined to the nasal cavity (37 patients), or extensive stage I E with an extension beyond the nasal cavity (46 patients). Thirty-one patients received radiotherapy alone. Thirty-four patients were treated with radiotherapy followed by 2-4 cycles of chemotherapy. Thirty-seven patients were treated with chemotherapy followed by radiotherapy and 3 with chemotherapy alone. Of 83 patients with stage I E disease, 26 were primarily treated with radiotherapy alone, 30 with. radiotherapy followed by chemotherapy, and 27 with chemotherapy followed by radiotherapy. Results: The five-year overall survival (OS) and progression-free survival rates (PIS) for all patients was 71% and 59%, respectively. The 5-year OS for stage I E and stage II E was 78% and 46% (P<0.01), while the 5-year PFS for stage I E and stage II E was 63% and 40%, respectively (P<0.01). Patients with limited stage I E had a better OS and PFS than those with extensive stage I E, with 5-year OS and PFS of 82% and 80% versus 75% and 45%, respectively. Complete response (CR) was achieved in 91 (87%) patients after radiotherapy and/or chemotherapy. Initial radiotherapy resulted in a superior CR as compared to initial chemotherapy, with 54 of 65 (83%) patients achieving CR with initial radiotherapy, versus only 8 of 40 (20%) with initial chemotherapy. For 102 patients who received radiotherapy with or without chemotherapy, the outcome of primary, treatment with radiotherapy alone was compared to that of CMT. Five-year OS and

    During the past 4 decades, the treatment of Hodgkin lymphoma has changed dramatically, and combined modality treatment is now considered the standard of care for patients with early-stage disease. However, the risk of late effects has led to concerns regarding the use of radiation therapy, especially in young patients with a long life expectancy. In this study, we review the current evidence for modern radiation therapy planning and delivery techniques in the treatment of early-stage Hodgkin lymphoma with a focus on a reduced delivered dose, a reduced irradiated volume, and a more conformal dose distribution. Although studies are difficult to compare because of differences in field technique, prescribed dose, target volumes, patient population, and reported dosimetric and plan evaluation parameters, modern radiation therapy significantly reduces exposure to normal tissues and thereby the estimated risk of late effects. However, there is no such thing as a single best modern delivery technique when multiple organs at risk are considered simultaneously because of the heterogeneity in patient anatomy and disease location, and the choice of radiation therapy technique should be made individually for each patient.

    The accurate detection and precise assessment of therapeutic responses is critical to the optimal management of patients with lymphoma. Over the past 50 years, dramatic advances in technology have established imaging as the cornerstone of disease evaluation. However, the appropriate application of current techniques requires acknowledgement of their strengths and weaknesses, and appreciation of the full diversity of lymphoid neoplasms. The role of anatomical and functional imaging in detection, treatment escalation/de-escalation and prognostication of patients with lymphoma can be misinterpreted. The development of disease assessment criteria, without an appreciation of the limitations of current imaging technologies, reflects a potential overreach of imaging science. Furthermore, the introduction of various novel therapies adds to the complexity of disease monitoring. In this Perspectives, the authors evaluate the available evidence in this rapidly evolving field and propose a reporting framework, named 'Specialist Integrated Haematological Malignancy Imaging Reporting' (SIHMIR), with a goal of providing a robust and adaptable system for lymphoma assessment. We predict a future model of multimodal disease assessment using novel molecular and imaging techniques, and highlight the key outstanding research questions in this field.

    The purpose of this retrospective study was to evaluate the accuracy of positron emission tomography (PET) using 18-F-fluorodeoxyglucose (FDG) in predicting lymphomatous involvement in the hilar and mediastinal regions in the staging and follow-up ofpatients with malignant lymphoma. One hundred forty-seven thoracic PET studies in 89 consecutive lymphoma patients were reviewed. Static FDG-PET imaging was performed following application of 270 MBq FDG (mean). Results of FDG-PET were compared with the findings of computed tomography (CT) in all patients and clinical follow-up examination. Eighty-nine of 147 (60%) PET studies showed no FDG uptake in the hilar or mediastinal regions, while 58 (40%) studied did detect FDG uptake in these regions. In 52 of 58 abnormal studies (90%), lymphomatous involvement of the hilar and/or mediastinal regions seen by CT was present. In the remaining six abnormal PET studies (10%), FDG uptake was considered as false-positive because of missing lesions on corresponding CT scans. In four patients false-positive FDG uptake was observed before treatment, in two patients after completion of therapy. In these two patients FDG uptake after therapy was caused by thymus hyperplasia. The remaining four cases before treatment remained unresolved. Sensitivity of FDG-PET was 96%, specificity 94%, positive predictive value 90%, and negative predictive value 98%, respectively. The present study suggests that FDG-PET has potential value in predicting lymphomatous involvement in the hilar and mediastinal regions. FDG-PET may obviate invasive diagnostic procedures in patients with lymphoma. (orig.)

Eighty-nine of 147 (60%) PET studies showed no FDG uptake in the hilar or mediastinal regions, while 58 (40%) studied did detect FDG uptake in these regions. In 52 of 58 abnormal studies (90%), lymphomatous involvement of the hilar and/or mediastinal regions seen by CT was present. In the remaining six abnormal PET studies (10%), FDG uptake was considered as false-positive because of missing lesions on corresponding CT scans. In four patients false-positive FDG uptake was observed before treatment, in two patients after completion of therapy. In these two patients FDG uptake after therapy was caused by thymus hyperplasia. The remaining four cases before treatment remained unresolved. Sensitivity of FDG-PET was 96%, specificity 94%, positive predictive value 90%, and negative predictive value 98%, respectively. The present study suggests that FDG-PET has potential value in predicting lymphomatous involvement in the hilar and mediastinal regions. FDG-PET may obviate invasive diagnostic procedures in patients with lymphoma. (orig.)

    BACKGROUND AND PURPOSE: Due to the long life expectancy after treatment, the risk of late effects after radiotherapy (RT) is of particular importance for patients with Hodgkin lymphoma (HL). Both deep inspiration breath hold (DIBH) and proton therapy have been shown to reduce the dose to normal...... tissues for mediastinal HL, but the impact of these techniques in combination is unknown. The purpose of this study was to compare the life years lost (LYL) attributable to late effects after RT for mediastinal HL using intensity modulated radiation therapy (IMRT) in free breathing (FB) and DIBH...

    Multiple randomized studies have demonstrated that chemotherapy, most commonly ABVD (doxorubicin [Adriamycin], bleomycin, vinblastine, dacarbazine), followed by consolidation radiation therapy is the most effective treatment program for early-stage Hodgkin lymphoma. With a combined-modality approach, the great majority of patients are cured of their disease. It is also apparent that both chemotherapy and radiation therapy can increase the risk of complications in the decades following treatment, with second cancers and cardiac disease being the most common. Most studies,evaluating such risks primarily include patients treated in decades past with what are now considered outdated approaches, including high-dose, wide-field radiation therapy. The treatment of Hodgkin lymphoma has evolved significantly, particularly in regard to radiation therapy. In combination with chemotherapy, much lower doses and smaller fields are employed, with success equivalent to that achieved using older methods. Many studies have shown a significant decline in both the rates of second cancers and the risk of cardiac disease with low-dose radiation confined to the original extent of disease. In favorable patients, as few as 2 cycles of ABVD have been shown to be effective. The current combined-modality approach seeks to maintain high cure rates but minimize risks by optimizing both chemotherapy and radiation therapy

    Although positron emission tomography with 18F-fluoro-2-deoxyglucose (FDG-PET/CT) has been recommended as the method of choice for lymphoma staging, it has limited availability in several countries, therefore, studies comparing whole-body magnetic resonance imaging (MRI) to conventional staging methods or to FDG-PET/CT are an important tool to establish whole-body MRI as an alternative to these methods. To compare whole-body MRI versus conventional imaging methods for staging of Hodgkin lymphoma in children and adolescents. The study included 22 patients ages 5 to 21 years. Staging was performed using conventional imaging methods and whole-body MRI. Conventional imaging methods were defined as computed tomography (CT) of the neck, chest, abdomen and pelvis and ultrasonography of the neck and/or abdomen. We calculated the sensitivity of these methods for Hodgkin lymphoma staging and their sensitivity and specificity for detecting sites of nodal and extranodal involvement. The sensitivity of whole-body MRI for Hodgkin lymphoma staging was superior to that of conventional imaging methods (95.5% vs. 86.4%, respectively), but both methods had similar sensitivity and specificity for detecting involvement of nodal sites (99.1% and 100% vs. 97.3% and 100%, respectively) and extranodal sites (90.5% and 98.7% vs. 90.5% and 99.4%, respectively). Whole-body MRI has excellent sensitivity for staging of Hodgkin lymphoma in children and adolescents. It can thus be considered an alternative for this purpose, particularly because it does not expose patients to ionizing radiation.

    Purpose: To determine the factors associated with the use of radiation therapy and associated survival outcomes in early-stage marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT). Methods and Materials: We extracted data on adult patients with stage I/II MALT lymphoma diagnoses between 1998 and 2010 recorded in the Surveillance, Epidemiology, and End Results (SEER) database. We studied factors associated with radiation therapy administration in a logistic regression model and described the cumulative incidence of lymphoma-related death (LRD) according to receipt of the treatment. The association of radiation therapy with survival was explored in multivariate models with adjustment for immortal time bias. Results: Of the 7774 identified patients, 36% received radiation therapy as part of the initial course of treatment. Older patients; black or Hispanic men; white, Hispanic, and black women; and socioeconomically disadvantaged and underinsured patients had a significantly lower chance of receiving radiation therapy. Radiation therapy administration was associated with a lower chance of LRD in most sites. In cutaneous, ocular, and salivary MALT lymphomas, the 5-year estimate of LRD after radiation therapy was 0%. The association of radiation therapy with overall survival in different lymphoma sites was heterogeneous, and statistically significant in cutaneous (hazard ratio 0.45, P=.009) and ocular (hazard ratio 0.47, P<.0001) locations after multivariate adjustment. Conclusions: Demographic factors are associated with the use of radiation therapy in MALT lymphoma. Clinicians should be sensitive to those disparities because the administration of radiation therapy may be associated with improved survival, particularly in cutaneous and ocular lymphomas.

    To assess the survival predicting value of TNM, Lugano, and Ann Arbor staging systems in patients with primary gastrointestinal lymphoma (PGL). 101 patients with PGL were reviewed. All of them were staged according to TNM, Lugano, or Ann Arbor staging system. Five-year survival overall survival/OS rate was used as major clinical outcome. The prognostic value of different variables like depth of tumor infiltration (T), lymph node status (N), metastasis (M), sex, age, LDH, ECOG performance status (PS), subtypes, and tumor sites were assessed in relation to clinical outcome. The median follow-up time was 46.6 months (range 1.3-158.6). The estimated 5-year OS rate was 74.22%. In gastric lymphoma ,the 5-year OS rate was well correlated with stage in the TNM system (stage I 100.00%, stage II 87.18%, stage III 75.17%, and stage IV 16.67%. pAnn Arbor systems (69.47% in stage IIE, 66.67% in stage IIIE). In aggressive lymphomas, the 5-year OS of TNM stage I, stage II, stage III , and stage IV was 100.00%, 81.34%, 63.52%, and 16.00%, respectively (p=0.0002), but there were overlapped survival curves in Lugano and Ann Arbor systems. The 5-year OS of patients with T1 or T2 was significantly superior compared to patients with T3 or T4 (96.15 vs 67.92%, p=0.0087), and multivariate Cox analysis showed that T (p=0.0181) and M (p=0.0031) were the covariates prognostically significant for OS. TNM staging system may be superior to Lugano and Ann Arbor system in predicting OS of patients with PGL.

    The diagnosis, prognostic factors, and optimal management of primary breast lymphomas (PBL) is difficult. Seven patients recorded at the Geneva Cancer Registry between 1973-1998 were reviewed. Five patient had diffuse large B-cell lymphoma, one a follicular lymphoma and one a MALT-lymphoma. All patients had clinical and radiological findings consistent with breast cancer and underwent mastectomy, which is not indicated in PBL. Diagnosis should be established prior to operative interventions, as fine needle aspiration missed the diagnosis for one patient and intra-operative frozen sections for 3 patients in our study. Five-year and 10-year overall survivals were 57% and 15%, respectively. Of the 3 patients who died from PBL, 2 had tumors that were Bcl-2 positive but Bcl-6 negative. All 3 surviving patients have positive Bcl-2 and Bcl-6 immunostaining, which could be important prognostic factors if confirmed by a larger study.

    The purpose of this study was to evaluate whole-body positron emission tomography (WB-PET) as a staging modality in Hodgkin's disease (HD) and non-Hodgkin lymphoma (NHL) and to compare it with computed tomography (CT) in a retrospective study. Seventy-one WB-PET studies using fluorodeoxyglucose (FDG) and 49 CT examinations were performed in 19 women and 31 men. Transaxial images were acquired and reformatted coronally and sagittally in PET. CT sections were obtained from the skull base to the pelvic floor. The written reports of the imaging data were compared with a reference standard constructed on the basis of all the data on the individual patients, including clinical follow-up of at least 6 months. The sensitivity and specificity of PET were, respectively, 86% and 96% for HD (n=53), and 89% and 100% for NHL (n=18). For CT sensitivity and specificity were 81% and 41% for HD (n=33) and 86% and 67% for NHL (n=16). Differences between PET and CT sensitivities were not significant, while in HD there was a significant difference in the specificity of PET and CT examinations, mainly because CT was unable to distinguish between active or recurrent disease and residual scar tissue after therapy. FDG tumour uptake was found in high- as well as low-grade NHL patients. In conclusion, PET appears to be highly sensitive and specific for staging of lymphoma. It is at least as sensitive as CT, and more specific, particularly in patients undergoing restaging, where a well-recognized diagnostic dilemma in CT is the presence of a post-therapeutic residual mass.

    Full Text Available Follicular lymphoma (FL is an indolent lymphoma with long median survival. Many studies have been performed to build up prognostic scores potentially useful to identify patients with poorer outcome. In 2004, an international consortium coordinated by the International Follicular Lymphoma Prognostic Factor project was established and a new prognostic study was launched (FLIPI2 using progression-free survival (PFS as main endpoint and integrating all the modern parameters prospectively collected. Low-grade non-Hodgkin lymphomas were once considered as a heterogenous group of lymphomas characterized by an indolent clinical course. Each entity is characterized by unique clinicobiologic features. Some studies have been focused on prognostic factors in single lymphoma subtypes, with the development of specific-entity scores based on retrospective series, for instance splenic marginal zone lymphoma (SMZL. A widely accepted prognostic tool for clinical usage for indolent non-follicular B-cell lymphomas is largely awaited. In this paper we summarized the current evidence regarding prognostic assessment of indolent follicular and non-follicular lymphomas.

    The International Prognostic Index (IPI) is used to determine prognosis in diffuse large B-cell lymphoma (DLBCL). One of the determinants of IPI is the stage of disease with bone marrow involvement being classified as stage IV. For the IPI, involvement on bone marrow is traditionally defined on the basis of histology with ancillary investigations used only in difficult cases to aid histological diagnosis. This study aimed to determine the effect of the routine use of flow cytometry, immunohistochemistry and molecular studies in bone marrow staging upon the IPI. Bone marrow trephines of 156 histologically proven DLBCL cases at initial diagnosis were assessed on routine histology, and immunohistochemistry using two T-cell markers (CD45RO and CD3), two B-cell markers (CD20 and CD79a) and kappa and lambda light chains. Raw flow cytometry data on all samples were reanalysed and reinterpreted blindly. DNA extracted from archived paraffin-embedded trephine biopsy samples was used for immunoglobulin heavy chain and light chain gene rearrangement analysis. Using immunophenotyping (flow cytometry and immunohistochemistry), 30 (19.2%) cases were upstaged to stage IV. A further 8 (5.1%) cases were upstaged using molecular studies. A change in IPI was noted in 18 cases (11.5%) on immunophenotyping alone, and 22 (14.1%) cases on immunophenotyping and molecular testing. Comparison of two revised IPI models, 1) using immunophenotyping alone, and 2) using immunophenotyping with molecular studies, was performed with baseline IPI using a Cox regression model. It showed that the revised IPI model using immunophenotyping provides the best differentiation between the IPI categories. Improved bone marrow staging using flow cytometry and immunohistochemistry improves the predictive value of the IPI in patients with DLBCL and should be performed routinely in all cases.

  12. Lymphoma-clinical questions

    International Nuclear Information System (INIS)

    Kim, H. C.

    2002-01-01

    Lymphoma is a group of neoplastic disease of lymphoid tissues, which can be classified into categories of Hodgkin's disease and non-Hodgkin's lymphoma(NHL). Prognosis of lymphoma depends on the extent of disease (staging) especially in Hodgkin's disease, but also depends on the histologic make up in non-Hodgkin's lymphoma. Although non-Hodgkin's lymphoma is a neoplastic transformation of lymphoid cell it is a collection of disease with morphologically and immunologically diverse make up. Consequently the classification of NHL has changed frequently and evolved according to the progress of immunologic and molecular knowledge added to the original morphologic classification. Lymphoma is a disorder sensitive to chemotherapy which often leads to cure of the disease even in advanced stage, while many other patients die from the progression of disease. Therefore, better understanding in newer classification and sensitive imaging technique, such as PET, in lymphoma will likely lead to the improvement of survival rate

    Purpose: This study aims to evaluate the outcome and pattern of failure in a large cohort of patients with Stage I NK/T-cell lymphoma of the upper aerodigestive tract treated with radiotherapy alone. Methods and Materials: The pathological diagnosis was confirmed using standard criteria. All patients were treated with high-dose extended-field radiotherapy alone. The median dose was 50 Gy. The primary tumor was located in the nasal cavity (n = 80), Waldeyer ring (n = 5), or oral cavity (n = 2). Results: The overall response to radiotherapy was achieved in 85 of 87 (97.7%) patients, with a complete response rate of 95.4% and a partial response rate of 2.3%. The 5-year overall survival, progression-free survival, and local control rates for all patients were 80%, 69%, and 93%, respectively. Twenty patients (23%) had disease progression or relapse. Of these, 15 patients (17%) developed systemic extranodal disseminations, whereas only 4 (5%) patients had local relapse and 4 (5%) patients had lymph node relapse. Conclusions: Our study suggests that high-dose extended-field radiotherapy alone is a curative therapy and shows favorable clinical outcome in patients with Stage I disease. With the high possibility of local control and primary failure of systemic dissemination, the integration of optimal radiotherapy with more effective systematic therapy is warranted to bring additional improvement to the outcome for these patients.

    Purpose: To examine the association between radiation therapy (RT) utilization and overall survival (OS) for patients with early-stage Hodgkin lymphoma (HL). Methods and Materials: Using the National Cancer Database, we evaluated clinical features and survival outcomes among patients diagnosed with stage I/II HL from 1998 to 2011. The association between RT use, covariables, and outcome was assessed in a Cox proportional hazards regression model. Propensity score matching was performed to balance observed confounding factors. Survival was estimated using the Kaplan-Meier method. Results: Among the 41,943 patients in the National Cancer Database with stage I/II HL, 29,752 patients were analyzed for this study. Radiation therapy use was associated with younger age (≤40 years), favorable insured status, higher socioeconomic status (income, education), and treatment at comprehensive community cancer centers (all P<.05). Five-year OS for patients receiving RT was 94.5%, versus 88.9% for those not receiving RT (P<.01). Radiation therapy use was a significant predictor of OS in the “As-Treated” cohort (hazard ratio 0.53, 95% confidence interval 0.49-0.58, P<.01) and intention-to-treat analysis (P<.01). After propensity score matching based on clinicopathologic characteristics, RT use remained associated with improved OS (hazard ratio 0.46, 95% confidence interval 0.38-0.56, P<.01). Over the study period, RT utilization for this cohort decreased from 55% to 44%, most commonly because it was not part of the planned initial treatment strategy. Conclusions: Consolidation RT was associated with improved OS for patients with early-stage classic HL. We also have identified patient-specific variations in the use of RT that may be targeted to improve patient access to care.

    2014-01-01

    Purpose: To evaluate dose plans for head and neck organs at risk (OARs) for classical Hodgkin lymphoma (HL) patients using involved node radiotherapy (INRT) delivered as 3D conformal radiotherapy (3DCRT), volumetric modulated arc therapy (VMAT), and intensity modulated proton therapy (PT), in comparison to the past mantle field (MF). Materials and methods: Data from 37 patients with cervical lymph node involvement were used. All patients originally received chemotherapy followed by 3DCRT–INRT (30.6 Gy). A VMAT–INRT, PT–INRT (both 30.6 Gy), and a MF plan (36 Gy) were simulated. Doses to head and neck OARs were compared with cumulative DVHs and repeated measures ANOVA. Results: The estimated median mean doses were 15.3, 19.3, 15.4, and 37.3 Gy (thyroid), 10.9, 12.0, 7.9, and 34.5 Gy (neck muscles), 2.3, 11.1, 1.8, and 37.1 Gy (larynx), 1.7, 5.1, 1.3, and 23.8 Gy (pharynx), 0.5, 0.8, 0.01, and 32.3 Gy (ipsilateral parotid), and 2.4, 3.8, 0.7, and 34.7 Gy (ipsilateral submandibular) with 3DCRT, VMAT, PT, and MF (all p < 0.0001), respectively. Conclusion: The use of INRT significantly lowered the estimated radiation dose to the head and neck OARs. VMAT appeared suboptimal compared to 3DCRT and PT, and for some patients, PT offered an additional gain

    Full Text Available PURPOSE: Radiation therapy (RT is commonly used as definitive treatment for early-stage nodular lymphocyte-predominant Hodgkin's lymphoma (NLPHL. We evaluated the cause-specific survival (CSS, overall survival (OS, and second malignancy (SM rates in patients with early-stage NLPHL treated with RT. METHODS AND MATERIALS: Patients with stage I-II NLPHL between 1988 and 2009 who underwent RT were selected from the Surveillance, Epidemiology and End Results database. Univariate analysis (UVA for CSS and Os was performed using the Kaplan-Meier method and included age, gender, involved site, year of diagnosis, presence of B-symptoms, and extranodal involvement (ENI. Multivariable analysis (MVA was performed using Cox Proportional Hazards modeling and included the above clinical variables. SM were classified as RT-related or non-RT-related. Freedom from SM and freedom from RT-related SM were determined using the Kaplan-Meier method. RESULTS: The study cohort included 469 patients. Median age was 37 years. The most common involved sites were the head and neck (36%, axilla/arm (26%, and multiple lymph node regions (18%. Sixty-eight percent had stage I disease, 70% were male, 4% had ENI, and 7% had B-symptoms. Median follow-up was 6 years. Ten-year CSS and Os were 98% and 88%, respectively. On UVA, none of the covariates was associated with CSS. Increasing age (p<0.01 and female gender (p<0.01 were associated with worse Os. On MVA, older age (p<0.01, female gender (p=0.04, multiple regions of involvement (p=0.03, stage I disease (p=0.02, and presence of B-symptoms (p=0.02 were associated with worse Os. Ten-year freedom from SM and freedom from RT-related SM were 89% and 99%, respectively. CONCLUSIONS: This is the largest series to evaluate the outcomes of stage I-II NLPHL patients treated with RT and found that this patient population has an excellent long-term prognosis and a low rate of RT-related second malignancies.

    Primary renal lymphoma (PRL) is a rare disease. We here present the case of an 8-year-old child who presented with bilateral renal masses. On biopsy, it was confirmed to be B-cell non-Hodgkin's lymphoma. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography-computed tomography (PET/CT) for staging demonstrated (18)F-FDG avid bilateral renal masses, with no other abnormal focus. Follow up (18)F-FDG PET/CT showed complete resolution of the disease after six cycles of chemotherapy. Here we have highlighted the potential role of (18)F-FDG PET/CT in staging and response evaluation of a patient with PRL and presented a brief review.

    The radiosensibility of Hodgkin's lymphoma (HL) is well established since 1902, when Pusey was one of the first to publish about radiotherapeutical treatment of a HL. In the early years, radiotherapy was the only curative treatment for this systemic disease, but the reports of Kaplan and Rosenberg and Peters in the fifties and seventies showed that irradiation of involved lymph node regions only resulted in high local and distant recurrences. The introduction of linear accelerator based high dose extended field (EF)-radiotherapy by Kaplan in Stanford was a milestone in the evolution of definitive curative radiotherapy strategies. The application of the mantle field for supradiaphragmatic and the inverted Y (with or without including the spleen or splenic pedicle) for infradiaphragmatic disease resulted in a dramatic improvement of survival rates in the early stages I and II (Ann Arbor) from 25-30% in the sixties to 65-80% in the eighties. Kaplan reported about a close relationship between radiation dose and cure rates in the case of definitive radiotherapy. A dose of at least 40 Gy resulted in local recurrences below 5% and is today the standard dose for radiotherapy only outside protocols. Despite complete remission rates after radiotherapy of 90-100%, the overall recurrence rate (including in-field, marginal and distant relapses) was between 20 and 30%. Analysis of the relapses revealed some stage migrating risk factors: large mediastinal mass, extra nodal involvement, number of involved lymph node areas ({>=} 3) and high ESR. The possibility of more accurate staging by using new imaging techniques like ultrasonography, CT and MRI as well as PET in the recent years resulted e.g. in the definition of early-favourable, early-unfavourable (intermediate) and high risk stages and more specific, risk adapted treatment strategies. The objective of this article is to show recent achievements and developments in the management of early-stage favourable HL exemplified

    This study aims to gain insight into patient-perceived communication barriers and facilitators at different stages after the diagnosis of malignant lymphoma. We have detected patterns to explain when these factors influence communication predominantly. A qualitative approach was applied, derived from the context mapping framework. A total of 28 patients completed a set of assignments about their experiences with provider-patient communication during medical consultations. Subsequently, these patients and nine companions shared their experiences during a semistructured (group) interview, which was recorded on audiotape. The audiotapes and assignments were analysed with MAXQDA software. From the patients' viewpoint, communicating effectively appears to depend on their own attributes (e.g. emotions), the health care professionals' attributes (e.g. attitude) and external factors (e.g. time pressure). Three patient communication states were identified: (i) overwhelmed, passive; (ii) pro-active, self-motivated; and (iii) proficient, empowered. Patients seem to behave differently in the three communication states. This study lists patient-perceived communication barriers and facilitators and identifies three different communication states, which indicate when certain barriers and facilitators are encountered. These findings may support health care professionals to tailor the provision of support and information and remove communication barriers accordingly. Additionally, they provide input for interventions to support patients in effective communication. Copyright © 2013 John Wiley & Sons, Ltd.

    Background and purpose: In a retrospective study, the efficacy of radiotherapy alone was compared with combined modality treatment in patients with stage I/IE non-Hodgkin's lymphoma (NHL). Patients and methods: Between 1980 and 1994, 296 patients with stage I/IE non-Hodgkin's lymphoma of intermediate or high grade malignancy (according to the Working Formulation) were treated in four different institutions. All patients were included except patients that presented with NHLs localized in the central nervous system, testis or skin. Two hundred two patients were treated with radiation therapy alone and 94 patients were treated with combined modality treatment. Results: Increasing age and radiation as a single treatment (versus combined modality treatment) were highly significant adverse prognostic factors by multivariate analysis. The actuarial 10-year rates for progression-free and overall survival were 83 and 70%, respectively, for the patients treated with combined modality treatment and 47 and 43%, respectively, for the patients treated with radiation therapy alone. Conclusion: Combined modality treatment is the treatment of choice for patients with stage I/IE intermediate and high grade non-Hodgkin's lymphomas.

    Fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) has been recommended as a complementary tool for the staging of various malignancies, including malignant lymphoma. PET findings often shift patients to higher stages and may affect treatment outcomes. In this study, we retrospectively compared staging and treatment outcomes of newly diagnosed diffuse large B-cell lymphoma (DLBCL) assessed by PET (n = 153) or gallium-67 scintigraphy (Ga) (n = 95). In total, Ga upstaged two (2.1%) of 95 patients, whereas PET upstaged 13 (8.5%) of 153 patients. Bone/bone marrow (15 vs. 4%, P = 0.01) and muscle lesion (5 vs. 0%, P = 0.03) were identified more frequently in the PET group than in the Ga group. The estimated 3-year overall and progression-free survival rates did not differ significantly in the two groups at any stage. However, patients with stage III disease tended to have better progression-free survival in the PET group than in the Ga group [92.3 (95% CI 56.6-98.9%) vs. 58.3% (95% CI 27.0-80.1%), P = 0.086]. These results suggest that PET has a greater potential in detecting musculoskeletal lesions of DLBCL as extranodal lesions than Ga, and may contribute to the optimal staging.

    To compare whole-body MRI, including diffusion-weighted imaging (whole-body MRI-DWI), with FDG-PET/CT for staging newly diagnosed paediatric lymphoma. A total of 36 children with newly diagnosed lymphoma prospectively underwent both whole-body MRI-DWI and FDG-PET/CT. Whole-body MRI-DWI was successfully performed in 33 patients (mean age 13.9 years). Whole-body MRI-DWI was independently evaluated by two blinded observers. After consensus reading, an unblinded expert panel evaluated the discrepant findings between whole-body MRI-DWI and FDG-PET/CT and used bone marrow biopsy, other imaging data and clinical information to derive an FDG-PET/CT-based reference standard. Interobserver agreement of whole-body MRI-DWI was good [all nodal sites together (κ = 0.79); all extranodal sites together (κ = 0.69)]. There was very good agreement between the consensus whole-body MRI-DWI- and FDG-PET/CT-based reference standard for nodal (κ = 0.91) and extranodal (κ = 0.94) staging. The sensitivity and specificity of consensus whole-body MRI-DWI were 93 % and 98 % for nodal staging and 89 % and 100 % for extranodal staging, respectively. Following removal of MRI reader errors, the disease stage according to whole-body MRI-DWI agreed with the reference standard in 28 of 33 patients. Our results indicate that whole-body MRI-DWI is feasible for staging paediatric lymphoma and could potentially serve as a good radiation-free alternative to FDG-PET/CT. (orig.)

    Doses and volumes of radiation therapy (RT) for early stages of Hodgkin lymphoma (HL) have been reduced over the last 30 years. Combined modality therapy (CMT) is currently the standard treatment for most patients with early-stage HL. The aim of this study was to analyze the site of relapse after RT according to the extent of radiation fields. Between 1987 and 2011, 427 patients were treated at our institution with RT ± chemotherapy for stage-I/II HL. Among these, 65 patients who experienced a relapse were retrospectively analyzed. Most patients had nodular sclerosis histology (86 %) and stage-II disease (75.9 %). Bulky disease was present in 21 % and 56 % of patients belonged to the unfavorable risk group according to European Organization for Research and Treatment of Cancer (EORTC)/The Lymphoma Study Association (LYSA) definitions. CMT was delivered to 91 % of patients. All patients received RT with doses ranging from 20 to 45 Gy (mean = 34 ± 5.3 Gy). The involved-field RT technique was used in 59 % of patients. The mean time between diagnosis and relapse was 4.2 years (range 0.3-24.5). Out-of-field relapses were suffered by 53 % of patients. Relapses occurred more frequently at out-of-field sites in patients with a favorable disease status, whereas in-field relapses were associated with bulky mediastinal disease. Relapses occurred later for favorable compared with the unfavorable risk group (3.5 vs. 2.9 years, p = 0.5). From multivariate analyses, neither RT dose nor RT field size were predictive for an in-field relapse (p = 0.25 and p = 0.8, respectively), only bulky disease was predictive (p = 0.018). In patients with bulky disease, RT dose and RT field size were not predictive for an in-field relapse. In this subgroup of patients, chemotherapy should be intensified. We confirmed the bad prognosis of early relapses. (orig.) [German] Waehrend der letzten 30 Jahre wurden die Strahlentherapie-(RT-)Dosis und die RT-Volumina fuer die Behandlung der Fruehstadien

    Purpose: This multicenter retrospective study was designed to evaluate the prognostic role of interim fluorodeoxyglucose-labeled positron emission tomography (i-FDG-PET) in a cohort of patients affected with early-stage Hodgkin lymphoma (HL) treated initially with adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy followed by radiation therapy, and to assess the role of chemotherapy continuation plus radiation therapy for i-FDG-PET-positive patients. Methods and Materials: Data from 257 patients were retrieved from 4 hematology and radiation oncology departments. Inclusion criteria were stage I to IIAB HL, “intention-to-treat” AVBD plus radiation therapy, and FDG-PET at diagnosis and after the first 2 ABVD cycles. All i-FDG-PET scans underwent blinded local review by using the Deauville 5-point scoring system; patients were stratified as negative or positive using 2 Deauville score cutoff values, ≥3 or ≥4. Results: Median follow-up time was 56 months (range: 9-163 months); 5-year overall survival (OS) and disease-specific survival (DSS) for the whole cohort were 97.5% and 98.3%, respectively. Five-year progression-free survival (PFS) was 95.6%. After i-FDG-PET revision, 43 of 257 patients (16.7%) had a positive i-FDG-PET (Deauville scores: 3-5). Five-year PFS rates for i-FDG-PET-negative and i-FDG-PET-positive patients were 98.1% and 83.7%, respectively, if using a Deauville score cutoff of 3, and 97.7% and 78.6%, respectively, if using a cutoff of 4 (P=.0001). Five-year OS for i-FDG-PET-negative and i-FDG-PET-positive patients was 98.5% and 93.0%, respectively, if using a cutoff of 3, and 98.6% and 89.3%, respectively, if using a cutoff of 4 (P=.029 and P=.002). At univariate regression analysis, i-FDG-PET positivity was associated with worse OS and PFS. At multivariate analysis, performed only for PFS, i-FDG-PET positivity confirmed its negative impact (P=.002). Conclusions: i-FDG-PET is prognostic for PFS and OS in early-stage HL

    Purpose: Image-guided intensity modulated radiation therapy (IG-IMRT) allows for margin reduction and highly conformal dose distribution, with consistent advantages in sparing of normal tissues. The purpose of this retrospective study was to compare involved-site IG-IMRT with involved-site 3D conformal RT (3D-CRT) in the treatment of early stage Hodgkin lymphoma (HL) involving the mediastinum, with efficacy and toxicity as primary clinical endpoints. Methods and Materials: We analyzed 90 stage IIA HL patients treated with either involved-site 3D-CRT or IG-IMRT between 2005 and 2012 in 2 different institutions. Inclusion criteria were favorable or unfavorable disease (according to European Organization for Research and Treatment of Cancer criteria), complete response after 3 to 4 cycles of an adriamycin- bleomycin-vinblastine-dacarbazine (ABVD) regimen plus 30 Gy as total radiation dose. Exclusion criteria were chemotherapy other than ABVD, partial response after ABVD, total radiation dose other than 30 Gy. Clinical endpoints were relapse-free survival (RFS) and acute toxicity. Results: Forty-nine patients were treated with 3D-CRT (54.4%) and 41 with IG-IMRT (45.6%). Median follow-up time was 54.2 months for 3D-CRT and 24.1 months for IG-IMRT. No differences in RFS were observed between the 2 groups, with 1 relapse each. Three-year RFS was 98.7% for 3D-CRT and 100% for IG-IMRT. Grade 2 toxicity events, mainly mucositis, were recorded in 32.7% of 3D-CRT patients (16 of 49) and in 9.8% of IG-IMRT patients (4 of 41). IG-IMRT was significantly associated with a lower incidence of grade 2 acute toxicity (P=.043). Conclusions: RFS rates at 3 years were extremely high in both groups, albeit the median follow-up time is different. Acute tolerance profiles were better for IG-IMRT than for 3D-CRT. Our preliminary results support the clinical safety and efficacy of advanced RT planning and delivery techniques in patients affected with early stage HL, achieving complete

    We adopted ABVD chemotherapy with risk-adapted radiation therapy (RT) as first-line therapy for children, adolescents and young adults with Hodgkin lymphoma (HL) in British Columbia in 2004. Patients ≤ 25 years diagnosed from 2004 to 2013 with all stages of HL who received ABVD as initial therapy were included. Among 55 children (age young adults (18-25 year), there were no significant differences among age groups for sex, histologic subtype, tumour bulk, B symptoms, prognostic risk groups or treatment received. The rates of complete response, partial response and progressive disease were 84%, 7% and 10% for children and 95%, 4% and 1% for young adults (P=0.01), respectively. Treatment failures in children all occurred within one year of completion, while 8/21 (38%) relapses in young adults occurred later (P=0.04). With a median follow-up of 66 months the 5-year progression-free (PFS) and overall survival (OS) were 85 ± 3% and 97 ± 1%, respectively. For limited stage disease, PFS was 90 ± 7% for children and 93 ± 3% for young adults (P=0.65); OS was 100% for both. For advanced stage patients, PFS and OS were also similar for the children and young adults (77 ± 7% versus 81 ± 4%; P=0.38 and OS 90 ± 6% versus 97 ± 2%; P=0.17). The rate of consolidative RT was low (21%) and did not differ between age groups. ABVD is an effective treatment in children, adolescents and young adults with HL. Children were less likely to achieve complete response and demonstrated earlier relapses compared to young adults. RT may be omitted for the majority of patients while maintaining excellent 5-year OS. © The Author 2017. Published by Oxford University Press on behalf of the European Society for Medical Oncology.

    2008-01-01

    Background and Purpose: The most commonly used approach for the assessment for differentiating malignant versus reactive lymph nodes is the measurement of the cross-section diameter of the lymph nodes in the transversal CT-planes. The intention of this article is to assess the impact of varying definitions of pathological lymph node size in CT-imaging in patients with Hodgkin lymphoma and to evaluate its effect on staging, chemotherapy regimes and radiation field size. Materials and methods: Pretherapeutic CT-scans of 10 consecutive patients with Hodgkin lymphoma have been evaluated based on two different definitions for malignant lymph node size; the classification of the German study group for Hodgkin lymphoma (1.0 cm) and the classification according to the results of the Cotswold consensus meeting 1989 (1.5 cm). Results: Applying the definitions of the DHSG and the Cotswold meeting we found more affected lymph node regions compared to the evaluation of the referring institutions in 9/10 and 6/10 patients, higher stages in 2/10 and 1/10 patients, more intense chemotherapy regimes in 3/10 and 1/10 and larger radiation fields in 10/10 and 6/10 patients, respectively. Conclusions: Varying definitions of pathologic lymph node size and inconsequent application of definitions reduce the comparability between different studies and within each study

    Full Text Available There are many therapies available for the management of low-grade lymphoma. With follicular lymphoma, for example, combination of chemotherapy and rituximab (immuno-chemo - therapy and consecutive maintenance therapy for 2 years is the current standard of care. To date, the most widely used regimen seems to be rituximab combined with cyclo phosphamide, doxorubicin, vincristine, and prednisone (RCHOP. Substitution of liposomal doxorubicin in place of conventional doxorubicin may improve outcomes in this indication, although evidence for its use in low-grade lymphoma is not as relevant as in aggressive lymphoma. Bendamustine, in combination with rituximab, has shown very good efficacy and tolerability in several lymphoma types, particularly follicular lymphoma and other low-grade lymphomas. Other combinations, such as those including bortezomib and lenalidomide, are under investigation in low-grade lymphoma, and the duration of rituximab maintenance therapy following bendamustine−rituximab-containing induction is being researched by the German Study Group for Indolent Lymphoma (StiL.

    Interim positron emission tomography after 2 cycles of ABVD (iPET-2) is a good predictor of outcome in advanced-stage classic Hodgkin lymphoma. So far, there are no other prognostic biomarkers capable of identifying chemotherapy refractory patients with comparable accuracy. Despite the considerable amount of evidence suggesting that antitumor immune surveillance is downregulated in classic Hodgkin lymphoma (cHL), few data exist on the impairment of natural killer cell function and the role of their killer immunoglobulin-like receptors (KIRs). We investigated KIR gene frequencies, KIR haplotypes, and KIR-ligand combinations in a cohort of 135 patients with advanced-stage classic Hodgkin lymphoma and 221 healthy controls. We furthermore evaluated the correlation of KIR genes and KIR haplotypes with the achievement of negative iPET-2. In the cohort of patients, the 5-year overall survival and progression-free survival were 93.6 and 79%, respectively. Homozygosity for KIR A haplotype and the HLA-C1 KIR ligand (KIR-AA/C1C1) was significantly higher in healthy controls (15.7 vs. 4.8%, p = 0.001). The KIR-AA genotype resulted to have a significant predictive power for achieving iPET-2 negativity (p = 0.039). Homozygosity for KIR A haplotype offers protection against classic Hodgkin lymphoma. The association found for the KIR-AA genotype and achievement of negative iPET-2 suggests that KIR-AA could be used in clinical practice to enhance the chemosensitivity predictive power of iPET-2. Our results point to the possibility of adapting treatment strategies based on the combination of KIR biomarkers and PET scan.

    Full Text Available Abstract Background Interim positron emission tomography after 2 cycles of ABVD (iPET-2 is a good predictor of outcome in advanced-stage classic Hodgkin lymphoma. So far, there are no other prognostic biomarkers capable of identifying chemotherapy refractory patients with comparable accuracy. Despite the considerable amount of evidence suggesting that antitumor immune surveillance is downregulated in classic Hodgkin lymphoma (cHL, few data exist on the impairment of natural killer cell function and the role of their killer immunoglobulin-like receptors (KIRs. Methods We investigated KIR gene frequencies, KIR haplotypes, and KIR-ligand combinations in a cohort of 135 patients with advanced-stage classic Hodgkin lymphoma and 221 healthy controls. We furthermore evaluated the correlation of KIR genes and KIR haplotypes with the achievement of negative iPET-2. Results In the cohort of patients, the 5-year overall survival and progression-free survival were 93.6 and 79 %, respectively. Homozygosity for KIR A haplotype and the HLA-C1 KIR ligand (KIR-AA/C1C1 was significantly higher in healthy controls (15.7 vs. 4.8 %, p = 0.001. The KIR-AA genotype resulted to have a significant predictive power for achieving iPET-2 negativity (p = 0.039. Conclusions Homozygosity for KIR A haplotype offers protection against classic Hodgkin lymphoma. The association found for the KIR-AA genotype and achievement of negative iPET-2 suggests that KIR-AA could be used in clinical practice to enhance the chemosensitivity predictive power of iPET-2.

    Full Text Available OBJECTIVE: To demonstrate a correlation of C-reactive protein levels with disease stage and response to treatment in Hodgkin's lymphoma patients of the Hematology Service of Santa Casa de São Paulo.METHODS: A retrospective study based on review of medical records was carried out of 38 patients diagnosed with Hodgkin's lymphoma between October 2010 and December 2012. Three patients met the exclusion criteria, giving a final sample of 35 patients for analysis. C-reactive protein levels >1 mg/dL were considered positive.RESULTS: Among the patients analyzed, median age was 29 years, 65% were male and 85% had the classical nodular sclerosis subtype. Twenty-nine (82% were in the advanced stage and 28% had bulky mass at diagnosis. Seventeen percent had bone marrow invasion by lymphoma. Baseline C-reactive protein levels were associated with both stage (p-value = 0.0035 and presence or absence of B symptoms (p-value = 0.008. The highest C-reactive protein levels were detected in patients with advanced disease while no patients with localized disease had C-reactive protein >5 mg/dL (p-value = 0.02. After the first treatment cycle, C-reactive protein fell to near-normal levels and no direct association with response pattern was found. As the mean follow-up was only 14 months, it was not possible to determine whether relapse was accompanied by a further increase in C-reactive protein.CONCLUSION: Baseline C-reactive protein levels directly correlated with stage and presence or absence of B symptoms, but the degree of improvement with treatment did not correlate with response pattern. After a longer follow-up, it may be possible to assess whether relapse correlates with a further increase in C-reactive protein levels.

    Usually, the middle-aged patients with non-Hodgkin's lymphoma and concomitant other adult diseases can not be tolerable for intensive chemotherapy. Then we introduced a new regimen composed of radiation for local and surrounding lymph node areas, and brief reduced-dose chemotherapy into treatment for such patients. Thirty-eight patients with Stage I E or Stage II E non-Hodgkin's lymphoma of the Waldeyer's ring were a core of this study. Histopathologically they were diagnosed as diffuse intermediate grade. In addition, they suffered from other adult diseases such as cardiovascular diseases, cereblovascular disorders, diabetes mellitus, chronic liver diseases, etc. They were treated by the combined modality composed of reduced-dose chemotherapy (70%-ACOP: 2 cycles or 70%-MACOP-B: 8 weeks) and regional lymph node irradiation (30 Gy) puls boost irradiation (10 Gy) to involved area (total 40 Gy). No relapses were observed in the radiation field, the 5-year disease-free survival rate and cause-specific survival rate for all patients were 85.7% and 91.4%, respectively. There were no differences of the 5-year disease-free survival rate between stage I E and II E , among the pathological subtypes, among the complications and etc. The regimen composed of regional lymph node irradiation (30 Gy) puls boost irradiation (10 Gy) to involved area (total 40 Gy) and reduced-dose chemotherapy (70%-dose ACOP, 70%-dose MACOP-B) is a safe and useful approach to treatment for diffuse intermediate grade of B cell lymphoma in middle-aged patients having other adult diseases.

    Purpose: To report the long-term outcome and patterns of relapse of a large cohort of marginal zone lymphoma (MZL) patients treated with curative-intent radiation therapy (RT) alone. Patients and Methods: We reviewed the charts of 490 consecutive patients with stage IE or IIE MZL referred between 1992 and 2012 to our institution. Of those, 244 patients (50%) were treated with RT alone. Pathology was confirmed by hematopathologists at our institution. Patient and disease factors were analyzed for association with relapse-free survival (RFS) and overall survival (OS). Results: Median age of the cohort was 59 years, and median follow-up was 5.2 years. Ann Arbor stage was IE in 92%. Most common disease sites were stomach (50%), orbit (18%), non-thyroid head-and-neck (8%), skin (8%), and breast (5%). Median RT dose was 30 Gy. Five-year OS and RFS were 92% and 74%, respectively. Cumulative incidence of disease-specific death was just 1.1% by 5 years. Sixty patients (24%) developed relapse of disease; 10 were in the RT field. Crude rate of transformation to pathologically confirmed large-cell lymphoma was 1.6%. On multivariable analysis, primary disease site (P=.007) was independently associated with RFS, along with age (P=.04), presence of B-symptoms (P=.02), and International Prognostic Index risk group (P=.03). All disease sites except for head-and-neck had worse RFS relative to stomach. Conclusion: Overall and cause-specific survival are high in early-stage extra-nodal MZL treated with curative RT alone. In this large cohort of 244 patients, most patients did not experience relapse of MZL after curative RT; when relapses did occur, the majority were in distant sites. Stomach cases were less likely to relapse than other anatomic sites. Transformation to large-cell lymphoma was rare.

    Objective: To evaluate the clinical impact of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) in staging of malignant lymphoma. Methods: Twenty-three patients with proven malignant lymphomas were prospectively enrolled. DWIBS (b = 0, 1000 s/mm{sup 2}) examinations and PET-CT were performed respectively on an Intera 1.5 T unit and a Gyroscan PET-CT scan (Philips Medical system, Best, the Netherland). The criteria for positive node involvement were a size over 10 mm or an apparent diffusion coefficient (ADC) value under 0.75 10{sup −3} mm{sup 2}/s for nodes under 10 mm. For extranodal analysis, a high or heterogeneous signal on DWIBS was considered as positive. In cases of discordance, the reference standard for each region or organ was established at 6 months after the diagnosis according to all available clinical, biological information, as well as histological evidence or follow-up to prove or disprove the presence of disease. Results: DWIBS and PET-CT results were congruent in 333 node regions on the 345 areas analyzed, with excellent agreement (κ = 0.97, P < 0.0001). From 433 organs analyzed (one patient had splenectomy) extranodal disease was detected in 22 organs on DWIBS. The two imaging techniques agreed on 430 organs (κ = 0.99, P < 0.0001). Finally, Ann Arbor stages based on DWIBS and those of PET/CT were in agreement for 23 patients. Conclusions: For malignant lymphoma in a pre-therapeutic context, agreement between diffusion-weighted whole-body imaging and PET/CT is high for Ann Arbor staging.

    Disease bulk is an important prognostic factor in early stage Hodgkin lymphoma, but its definition is unclear in the computed tomography era. This retrospective analysis investigated the prognostic significance of bulky disease measured in transverse and coronal planes on computed tomography imaging. Early stage Hodgkin lymphoma patients (n=185) treated with chemotherapy with or without radiotherapy from 2000-2010 were included. The longest diameter of the largest lymph node mass was measured in transverse and coronal axes on pre-treatment imaging. The optimal cut off for disease bulk was maximal diameter greater than 7 cm measured in either the transverse or coronal plane. Thirty patients with maximal transverse diameter of 7 cm or under were found to have bulk in coronal axis. The 4-year overall survival was 96.5% (CI: 93.3%, 100%) and 4-year relapse-free survival was 86.8% (CI: 81.9%, 92.1%) for all patients. Relapse-free survival at four years for bulky patients was 80.5% (CI: 73%, 88.9%) compared to 94.4% (CI: 89.1%, 100%) for non-bulky; Cox HR 4.21 (CI: 1.43, 12.38) (P=0.004). In bulky patients, relapse-free survival was not impacted in patients treated with chemoradiotherapy; however, it was significantly lower in patients treated with chemotherapy alone. In an independent validation cohort of 38 patients treated with chemotherapy alone, patients with bulky disease had an inferior relapse-free survival [at 4 years, 71.1% (CI: 52.1%, 97%) vs 94.1% (CI: 83.6%, 100%), Cox HR 5.27 (CI: 0.62, 45.16); P=0.09]. Presence of bulky disease on multidimensional computed tomography imaging is a significant prognostic factor in early stage Hodgkin lymphoma. Coronal reformations may be included for routine Hodgkin lymphoma staging evaluation. In future, our definition of disease bulk may be useful in identifying patients who are most appropriate for chemotherapy alone. Copyright© Ferrata Storti Foundation.

    The place of positron emission tomography (PET) in the evaluation of diffuse at big cells B lymphomas and hodgkin lymphomas is validated. The clinical impact of the PET registered in end of therapy development is indisputable. recommendations must be followed for images interpretation. The PET is strongly recommended during the first evaluation of the disease because it is a reference examination that makes easy the interpretation at the end of the therapy and allows to evaluate the extension of the disease with a sensitivity and a specificity superior to the computerized tomography. the prognosis value of intermediate evaluations appears certain in the diffuse at big cells B lymphomas and the hodgkin lymphomas but the impact of an early therapy change induced by PET is still to determine. The criteria of interpretation of early evaluations are to standardize. for the other types of lymphomas, the PET can have an interest to confirm the the localized stages, especially for the follicular lymphomas and direct the biopsy for a patient ill of a low range lymphoma suspect of aggressive change.

    Published criteria to distinguish benign colloid nodules from follicular neoplasms emphasize only three interdependent features: size of follicles, amount of colloid, and cellularity. There is a need for the validation of other independent criteria. This study quantified the significance of cystic change, defined as presence of macrophages, and the presence of hemosiderin in either the macrophages or follicular cells. The cohort consisted of 165 patients with fine needle aspiration (FNA) and histologic follow-up of either goiter (101), follicular adenoma (47), or follicular carcinoma (17). Papillary thyroid carcinomas and Hürthle cell neoplasms were excluded from the cohort, because these categories are known to show cystic change and hemosiderin. FNAs were reviewed blindly with the most cellular slide scored for the presence of macrophages and/or hemosiderin. Hemosiderin within macrophages were seen in 67% (68 of 101) of the goiters and only 6% (four of 64) of follicular neoplasms (Phemosiderin in macrophages were adenomas. Three of these four had equivocal features of a benign colloid nodule histologically. None of the 17 follicular carcinomas had hemosiderin in macrophages (Phemosiderin also strongly distinguished goiters from neoplasms (83% vs 17%) but appears less useful as a criterion since macrophages were present within 3 of 17 follicular carcinomas. Hemosiderin within follicular epithelial cells was present in 18% (18 of 101) of goiters, whereas none of the 64 follicular neoplasms had intraepithelial hemosiderin (Phemosiderin virtually excludes a clinically significant follicular neoplasm.

    Patients with advanced stage Hodgkin lymphoma still present unsatisfactory outcomes. The Groupe d'étude des Leucémies Aigues et des Maladies du Sang (GOELAMS) group conducted a prospective multicentric trial (NCT00920153) for advanced stage Hodgkin lymphoma to evaluate a positron emission tomography (PET)-adapted strategy. Patients received an intensive regimen (VABEM [vindesine, doxorubicin, carmustine, etoposide, and methylprednisolone]) in front-line and interim 18F FDG-PET evaluation after 2 courses (PET-2). Patients with negative PET-2 findings received 1 additional course. Patients with positive PET-2 findings underwent early salvage therapy followed by high-dose therapy/autologous stem cell transplantation. Fifty-one patients were included. The final complete remission rate was 88%. With a median follow up of 5.3 years, 5-year event-free survival and overall survival rates were 75.3% and 85.3%, respectively, for the whole cohort. Patients who were PET-2-negative had 5-year event-free survival and overall survival rates of, respectively, 77.8% and 88.2% versus 85.1% and 91.7% for patients who were PET-2-positive. A PET-guided strategy with early salvage therapy and high-dose therapy/autologous stem cell transplantation for patients with interim PET-2-positive findings is safe and feasible and provide similar outcome as patients with a negative PET-2.

  10. Hodgkin Lymphoma Mimicking Osteomyelitis

    Full Text Available Hodgkin lymphoma with symptomatic osseous involvement can have a similar presentation to osteomyelitis. Common findings in symptoms, laboratory workup, and imaging can make it very difficult to distinguish between the two diseases. Excisional biopsy should be pursued if fine-needle biopsy is equivocal and suspicion of lymphoma is high. We report a case of a 40-year-old man who presented with a history of marine animal sting on his neck and later developed erythema in the area, chest pain, constitutional symptoms, adenopathy, and imaging classic for sternal osteomyelitis. Fortunately, initial biopsy prompted the possibility of lymphoma, and further workup was initiated, which confirmed Hodgkin lymphoma. This case is a good reminder that malignancies and infections can share many common features, and keeping a broad differential diagnosis can be lifesaving. Proper staging and risk stratification of Hodgkin lymphoma help determine the optimal treatment.

    Full Text Available Introduction: endoscopic ultrasonography (EUS has already proven useful in the assessment of submucosal lesions, and the staging of gastrointestinal cancer, particularly gastric MALT-type lymphoma. The goal of this paper was EUS staging. Patients and method: 24 patients (10 females, 14 males with a median age of 56 years and possibly gastric MALT lymphoma (25 cases were studied using videoendoscopy, biopsies, and echoendoscopy with 7.5- and 20-MHz radial EUS, and also with 12- and 20-MHz miniprobes (MPs. Nineteen patients were definitely evaluated (7 females, 12 males as having 20 MALT-type lymphomas, as five patients were post-hoc disregarded when an invasive, high-grade gastric lymphoma (3c or plasmocytoma (2c was subsequently demonstrated. Of these 19 patients, all had T1 lesions except for two with T2 lesions; one patient had a gastroduodenal T1 lymphoma. Echographic findings with MPs were compared to EUS (gold standard and histology both before and after eradication. Then, patients were followed up every 1-3-6 months using videoendoscopy and MPs. Results: echoendoscopy correctly identified T stages in 90% of cases. MPs identified T stages in 88% of cases, and N stages in 33% of cases, with results being slightly inferior to those obtained with conventional EUS (91 vs. 45%; they were consequently used for follow-up. After eradication, all but two patients are in complete remission and have been followed every 1-3-6 months using MPs without echographic abnormalities, except for a patient who relapsed.Introducción: la ultrasonografía endoscópica (USE ha demostrado ya su utilidad en la evaluación de las lesiones submucosas, en la estadificación del cáncer digestivo en general, y del linfoma gástrico tipo MALT en particular.

    Full Text Available Primary thyroid lymphoma (PTL is a rare malignancy and represents 2%–5% of all thyroid malignancies and 1%–2.5% of all malignant lymphomas. We present our institute’s experience in combined modality management of 16 successive patients of PTL treated from 2005 to 2010. The median age of the patients was 56.0 years. Five patients were males, and 11 patients were females. An enlarging thyroid mass was the most common presenting symptom. 14 patients had diffuse large B-cell lymphoma, and 2 patients had follicular lymphoma. The most common stage of presentation was stage II comprising 6 (37.5% patients. All patients received CCT, and only 12 patients received involved field RT with a median dose of 36.0 Gy. 10 patients (62.5% had CR, and 6 patients (27.5% had PR. Eight patients had disease progression in subsequent followup and this included the initial 6 patients with PR. The 5-year DFS was 40.0%, and median DFS was 47 months. The 5-year OS was 41.0%, and median OS was 51 months. Most common presentation in our series was locally advanced tumors. Most of these patients require combined modality management. Risk-adapted and multimodality approach is the need of the hour to achieve good control rates while minimizing treatment related toxicity.

    The international staging system (ISS), based on serum beta-2 microglobulin and albumin, is used to predict survival in multiple myeloma, but its prognostic significance in diffuse large B-cell lymphoma (DLBCL) remains unknown. Herein, we retrospectively analyzed 215 de novo DLBCL patients. According to ISS, there were 90 of 215 (41.9%) patients in stage I, 98 of 215 (45.6%) in stage II and 27 of 215 (12.6%) in stage III group. Patients with ISS stage II/III showed shorter overall survival (OS) and event free survival (EFS) than those with stage I treated with R-CHOP (p = 0.012 and p = 0.043, respectively), but not those treated with CHOP regimen (p > 0.05). Multivariable analysis revealed that ISS, independent of IPI, indicated different survival in both OS (HR, 5.690; 95% CI, 1.270-25.495, p = 0.023) and EFS (HR, 2.116; 95% CI, 1.005-4.455, p = 0.049) in DLBCL patients treated with R-CHOP. ISS could identify patients with better outcome in intermediate-high/high IPI risk patients (p IPI risk patients, which may help to avoid intensive therapy.

    Purpose: Early stage peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) is rare. The purpose of this study was to evaluate the outcome of treatment as well as the potential role of radiation therapy in PTCL-NOS. Methods and Materials: Thirty-five patients with early stage PTCL-NOS were included. There were 13 patients with stage I disease and 22 with stage II. All patients except 1 received doxorubicin-based chemotherapy alone (n=13) or a combination of chemotherapy and radiation therapy (CMT) (n=21). Results: The 3-year overall survival (OS) and progression-free survival (PFS) rates for the entire group were 41.3% and 25.7%, respectively. The addition of radiation therapy to chemotherapy significantly improved OS and PFS in early stage PTCL-NOS. The 3-year OS and PFS rates were 49.7% and 33.3% for CMT, compared with 23.1% (P=.042) and 15.4% (P=.035) for chemotherapy alone, respectively. The prognosis for patients who achieved a complete response (CR) was significantly better than that observed in those who did not achieve a CR. Conclusions: Despite the aggressive clinical course of early stage PTCL-NOS, additional radiation therapy has a significant impact on outcome. The integration of local radiation therapy into more effective systemic therapies may further improve survival

    To determine whether pre-treatment neutrophil/lymphocyte (NLR) or platelet/lymphocyte ratios (PLR) are predictive for progression in early-stage classical Hodgkin lymphoma (cHL), we derived NLR and PLR values for 338 stage I/II cHL patients and appropriate cut-off point values to define progression. Two-year freedom from progression (FFP) for patients with NLR ≥6·4 was 82·2% vs. 95·7% with NLR <6·4 (P < 0·001). Similarly, 2-year FFP was 84·3% for patients with PLR ≥266·2 vs. 96·1% with PLR <266·2 (P = 0·003). On univariate analysis, both NLR and PLR were significantly associated with worse FFP (P = 0·001). On multivariate analysis, PLR remained a significant, independent prognostic factor (P < 0·001). © 2017 John Wiley & Sons Ltd.

  16. Endoscopic Ultrasound Fine Needle Aspiration in the Diagnosis of Lymphoma

    Full Text Available In recent years, endoscopic ultrasound techniques with Fine Needle Aspiration (FNA have become an increasingly used diagnostic aid in the differentiation of mediastinal lymphadenopathy. Endobronchial ultrasound (EBUS and endoesophageal ultrasound (EUS are now available for clinicians to reach mediastinal and paramediastinal masses using a minimally invasive approach. These techniques are an established component for diagnosing and staging lung cancer and their benefit in the diagnosis of lymphoma's has been highlighted in a number of case studies. However, the lack of tissue architecture obtained by cytological FNA specimens decreases the diagnostic accuracy for benign causes of thoracic lymphadenopathies, lymphomas, and histopathological subtyping of lung cancer. Accordingly, our study group have adapted the FNA sampling technique, resulting in tissue fragments that can be used for histopathological examinations. As an illustration, we report a case of follicular non-Hodgkin lymphoma, diagnosed on tissue fragments obtained by adjusted EUS FNA. We believe that this relatively simple adjustment to routine FNA sampling can help to overcome the diagnostic limitations inherent in cytology obtained by routine FNA.

    The incidence of extra nodal non Hodgkin lymphoma (ENL) is rising throughout the world. However, data regarding ENL as a group is limited. The aim was to study the epidemiological and histomorphological trends of primary ENL (pENL) in India. The biopsy materials from sixty eight patients with pENL (45 male, 23 female, M:F= 1.9:1), diagnosed over a five year period (2005-2009), were analysed and pathologically reclassified according to the World Health Organization (WHO) classification, 2008 criteria. Primary extra nodal non Hodgkin lymphomas constituted 22.0% (68/308) of all non Hodgkin lymphomas (NHL). The mean age at presentation for pENL and primary nodal NHL was 43 years and 58 years, respectively with a male predilection (M: F=2:1). Central nervous system (CNS) constituted the most common extranodal site (20/68, 29.5%) followed by gastrointestinal tract (17/68, 25%), and nose/nasopharynx (8/68, 11.8%). Diffuse large B-cell lymphoma (DLBCL, not otherwise specified), extranodal marginal lymphoma of mucosa associated lymphoid tissue (MALT) type, and B cell NHL unclassified (U) were the three most common histological types observed. T-cell phenotype was rarely noted (4%). Follicular lymphomas and anaplastic large cell lymphoma, seen among nodal NHL, were absent at extra nodal sites. Majority (41/68, 60%) of the patients with pENL were immunocompetent and 55% were in stage I-II with favorable prognosis. Central nervous system was the most common site of ENL, followed by gastrointestinal tract. Majority of pENL occurred in immunocompetent hosts with a favorable prognosis.

  18. Can metabolic tumor parameters on primary staging18F-FDG PET/CT aid in risk stratification of primary central nervous system lymphomas for patient management as a prognostic model?

    Primary central nervous system (CNS) lymphoma is an aggressive and fatal extranodal non-Hodgkin lymphoma jailed in CNS at initial diagnosis. Its prognosis is poor and the disease has a fatal outcome when compared with systemic non-Hodgkin lymphoma. A few baseline risk stratification scoring systems have been suggested to estimate the prognosis mainly based on serum lactate dehydrogenase level,age, Karnofsky performance score, involvement of deep brain structures and cerebrospinal fluid protein concentration. 18 F-FDG PET/CT has a high prognostic value with respect to overall survival and disease-free survival in many cancers and lymphomas. We aimed to investigate metabolic tumor indexes on primary staging 18 F-FDG PET/CT as prognostic markers in primary CNS lymphoma. Fourteen patients with primary CNS diffuse large B-cell lymphoma (stage i) were enrolled in this retrospective cohort study. Primary staging 18 F-FDG PET/CT was performed and quantitative parameters like maximum standardized uptake value, average standardized uptake value, metabolic tumor volume and total lesion glycolysis (TLG) were calculated for all patients before the treatment. Cox regression models were performed to determine their relation with survival time. In the evaluation of all potential risk factors impacting recurrence/metastases (age, sex, serum lactate dehydrogenase, involvement of deep brain structures, maximum standardized uptake value, average standardized uptake value, metabolic tumor volume, and TLG) with univariate analysis, TLG remained statistically significant (P=.02). Metabolic tumor parameters are useful in prognosis estimation of primary CNS lymphomas, especially TLG, which is the most important one and may play a role in patient management.

  19. Lymphoma-clinical questions

    2002-07-01

    Lymphoma is a group of neoplastic disease of lymphoid tissues, which can be classified into categories of Hodgkin's disease and non-Hodgkin's lymphoma(NHL). Prognosis of lymphoma depends on the extent of disease (staging) especially in Hodgkin's disease, but also depends on the histologic make up in non-Hodgkin's lymphoma. Although non-Hodgkin's lymphoma is a neoplastic transformation of lymphoid cell it is a collection of disease with morphologically and immunologically diverse make up. Consequently the classification of NHL has changed frequently and evolved according to the progress of immunologic and molecular knowledge added to the original morphologic classification. Lymphoma is a disorder sensitive to chemotherapy which often leads to cure of the disease even in advanced stage, while many other patients die from the progression of disease. Therefore, better understanding in newer classification and sensitive imaging technique, such as PET, in lymphoma will likely lead to the improvement of survival rate.

  20. Utility of LRF/Pokemon and NOTCH1 protein expression in the distinction between nodular lymphocyte-predominant Hodgkin lymphoma and classical Hodgkin lymphoma.

    Classical Hodgkin lymphoma (CHL) and nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) are considered separate entities with different prognosis and treatment. However, morphologic features can be similar and immunohistochemical studies are essential in the distinction; thus, determination of additional biomarkers is of utmost importance. LRF/Pokemon is a proto-oncogene, an interacting partner co-expressed with BCL6 in germinal centers and highly expressed in diffuse large B-cell lymphoma and follicular lymphoma. Conversely, loss of the LRF gene in mouse hematopoietic stem cells results in complete block of early B cell development with concomitant Notch de-repression, indicating its critical role in B versus T cell fate decision at the hematopoietic stem cell stage. For the first time, we show that LRF/Pokemon is predominantly expressed in NLPHL cases as is BCL6 with low to absent NOTCH1 protein expression; while Hodgkin Reed-Sternberg (HRS) cells in CHL show low to absent BCL6 and LRF/Pokemon expression with higher NOTCH1 expression. We illustrate a potential functional interaction between LRF and BCL6 in NLPHL pathogenesis, and differential expression of LRF/Pokemon and NOTCH1 proteins in CHL thus showing differential expression, making for an additional diagnostic marker and therapeutic target.

    Full Text Available Background: Published criteria to distinguish benign colloid nodules from follicular neoplasms emphasize only three interdependent features: size of follicles, amount of colloid, and cellularity. There is a need for the validation of other independent criteria. Methods: This study quantified the significance of cystic change, defined as presence of macrophages, and the presence of hemosiderin in either the macrophages or follicular cells. The cohort consisted of 165 patients with fine needle aspiration (FNA and histologic follow-up of either goiter (101, follicular adenoma (47, or follicular carcinoma (17. Papillary thyroid carcinomas and Hürthle cell neoplasms were excluded from the cohort, because these categories are known to show cystic change and hemosiderin. FNAs were reviewed blindly with the most cellular slide scored for the presence of macrophages and/or hemosiderin. Results: Hemosiderin within macrophages were seen in 67% (68 of 101 of the goiters and only 6% (four of 64 of follicular neoplasms ( P < .0001. All four follicular neoplasms with hemosiderin in macrophages were adenomas. Three of these four had equivocal features of a benign colloid nodule histologically. None of the 17 follicular carcinomas had hemosiderin in macrophages ( P < .12. Macrophages without hemosiderin also strongly distinguished goiters from neoplasms (83% vs 17% but appears less useful as a criterion since macrophages were present within 3 of 17 follicular carcinomas. Hemosiderin within follicular epithelial cells was present in 18% (18 of 101 of goiters, whereas none of the 64 follicular neoplasms had intraepithelial hemosiderin ( P < .0003. Conclusions: If papillary thyroid carcinoma and Hürthle cell neoplasm are ruled out, our findings indicate that the presence of hemosiderin virtually excludes a clinically significant follicular neoplasm.

    Purpose: To review our institutional experience with primary orbital lymphoma and determine the prognostic factors for survival, local control, and distant metastases. In addition, we also analyzed the risk factors for complications in the radiotherapeutic management of this tumor. Methods and Materials: Between 1973 and 1998, 47 patients (29 women [62%] and 18 men [38%], median age 69 years, range 32-89) with Stage IAE orbital lymphoma were treated with curative intent at one department. Five had bilateral orbital involvement. The tumor was located in the eyelid and extraocular muscles in 23 (44%), conjunctiva in 17 (33%), and lacrimal apparatus in 12 (23%). The histologic features according to the World Heath Organization classification of lymphoid neoplasms was follicular lymphoma in 25, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type in 8, diffuse large B-cell lymphoma in 12, mantle cell lymphoma in 6, and peripheral T-cell lymphoma in 1. For the purposes of comparison with the existing literature on orbital lymphomas, the grading system according to the Working Formulation was also recorded. The histologic grade was low in 33 (63%), intermediate in 18 (35%), and high in 1 (2%). All patients were treated with primary radiotherapy alone. The median dose for low-grade tumors was 3000 cGy (range 2000-4020); the median dose for intermediate and high-grade tumors was 4000 cGy (range 3000-5100). A lens-sparing approach was used in 19 patients (37%). Late complications for the lens and cornea were scored according to the subjective, objective, management, and analytic (SOMA) scale of the Late Effects of Normal Tissue (LENT) scoring system. The median follow-up was 55 months (range 6-232). Results: The local control rate was 100% in the 52 orbits treated. The 5-year overall survival and relapse-free survival rate was 73.6% and 65.5%, respectively. Tumor grade and location did not predict for overall survival or relapse-free survival

    As the optimal treatment for primary mediastinal large B-cell lymphoma (PMBCL) remains undefined, we evaluated outcomes of patients treated with standard and dose-intense rituximab-chemotherapy (R-CT) with and without radiotherapy (RT). We retrospectively identified 28 patients with stage I-II PMBCL in our lymphoma database, re-reviewed pathology slides and scored interim or post-chemotherapy PET/CTs using the Deauville scale. Fourteen patients received RT (36-45 Gy) preceded by either six cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or 12 weeks of rituximab, etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone and bleomycin (R-VACOP-B) with median follow-up of 94 months. Fourteen patients received 4-8 cycles of dose-adjusted etoposide, vincristine, doxorubicin, cyclophosphamide and rituximab (DA-EPOCH-R) with median follow-up of 38 months; one of these received RT (36 Gy) due to post-chemotherapy PET/CT Deauville score 4. Following R-CT and RT or DA-EPOCH-R, 5-year and 3-year FFP and OS were both 100%. Both R-CHOP/R-VACOP-B with RT and DA-EPOCH-R demonstrate excellent outcomes.

    2009-01-01

    Purpose: To compare the dose distribution to targeted and nontargeted tissues in Hodgkin's lymphoma patients using conventional radiotherapy (CRT), intensity-modulated RT (IMRT), and three-dimensional proton RT (3D-PRT). Methods and Materials: CRT, IMRT, and 3D-PRT treatment plans delivering 30 cobalt Gray equivalent (CGE)/Gy to an involved nodal field were created for 9 Stage II Hodgkin's lymphoma patients (n = 27 plans). The dosimetric endpoints were compared. Results: The planning target volume was adequately treated using all three techniques. The IMRT plan produced the most conformal high-dose distribution; however, the 3D-PRT plan delivered the lowest mean dose to nontarget tissues, including the breast, lung, and total body. The relative reduction in the absolute lung volume receiving doses of 4-16 CGE/Gy for 3D-PRT compared with CRT ranged from 26% to 37% (p < .05), and the relative reduction in the absolute lung volume receiving doses of 4-10 CGE/Gy for 3D-PRT compared with IMRT was 48-65% (p < .05). The relative reduction in absolute total body volume receiving 4-30 CGE/Gy for 3D-PRT compared with CRT was 47% (p < .05). The relative reduction in absolute total body volume receiving a dose of 4 CGE/Gy for 3D-PRT compared with IMRT was 63% (p = .03). The mean dose to the breast was significantly less for 3D-PRT than for either IMRT or CRT (p = .03) The mean dose and absolute volume receiving 4-30 CGE/Gy for the heart, thyroid, and salivary glands were similar for the three modalities. Conclusion: In this favorable subset of Hodgkin's lymphoma patients without disease in or below the hila, 3D-PRT significantly reduced the dose to the breast, lung, and total body. These observed dosimetric advantages might improve the clinical outcomes of Hodgkin's lymphoma patients by reducing the risk of late radiation effects related to low-to-moderate doses in nontargeted tissues.

    2016-01-01

    Background: Primary mediastinal B cell lymphoma (PMBCL) is an uncommon lymphoma for which trials are few with small patient numbers. The role of radiation therapy (RT) after standard immunochemotherapy for early-stage disease has never been studied prospectively. We used the Surveillance, Epidemiology, and End Results (SEER) database to evaluate PMBCL and the impact of RT on outcomes. Methods and Materials: We queried the SEER database for patients with stage I-II PMBCL diagnosed from 2001 to 2011. Retrievable data included age, gender, race (white/nonwhite), stage, extranodal disease, year of diagnosis, and use of RT as a component of definitive therapy. Kaplan-Meier overall survival (OS) estimates, univariate (UVA) log-rank and multivariate (MVA) Cox proportional hazards regression analyses were performed. Results: Two hundred fifty patients with stage I-II disease were identified, with a median follow-up time of 39 months (range, 3-125 months). The median age was 36 years (range, 18-89 years); 61% were female; 76% were white; 45% had stage I disease, 60% had extranodal disease, and 55% were given RT. The 5-year OS for the entire cohort was 86%. On UVA, OS was improved with RT (hazard ratio [HR] 0.446, P=.029) and decreased in association with nonwhite race (HR 2.70, P=.006). The 5-year OS was 79% (no RT) and 90% (RT). On MVA, white race and RT remained significantly associated with improved OS (P=.007 and .018, respectively). The use of RT decreased over time: 61% for the 67 patients whose disease was diagnosed from 2001 to 2005 and 53% in the 138 patients treated from 2006 to 2010. Conclusion: This retrospective population-based analysis is the largest PMBCL dataset to date and demonstrates a significant survival benefit associated with RT. Nearly half of patients treated in the United States do not receive RT, and its use appears to be declining. In the absence of phase 3 data, the use of RT should be strongly considered for its survival benefit in early-stage

    2016-10-01

    Purpose: To assess the dosimetric benefit, prognosis, and toxicity of intensity modulated radiation therapy (IMRT) for early-stage, diffuse large B-cell lymphoma of Waldeyer ring (WR-DLBCL). Methods and Materials: Sixty-one patients with early-stage WR-DLBCL who received chemotherapy followed by IMRT were retrospectively reviewed. Dosimetric parameters for the target volume and critical normal structures were evaluated, and survival was calculated. Linear regression analysis was used to assess the effect of the mean dose (D{sub mean}) to the parotid glands on xerostomia. Results: The median conformity index and homogeneity index of the planning target volume (PTV) were 0.83 and 0.90, respectively, demonstrating very good coverage of the target volume. The mean dose to the parotid glands was 24.9 Gy. The 5-year overall survival (OS), progression-free survival (PFS), and locoregional control (LRC) were 94.7%, 93.1%, and 98.3%, respectively. Early and late toxicities were mild, and no patient experienced late grade ≥3 toxicities. The D{sub mean} to the parotid glands had a linear correlation with late grade ≥2 xerostomia. Conclusions: IMRT after chemotherapy can provide excellent dose conformity and achieve favorable survival and LRC with mild toxicities in patients with early-stage WR-DLBCL. Dose constraints for the parotid glands should be limited to <24 Gy for early-stage WR-DLBCL.

    Purpose: The purpose of this study was to evaluate the possible effect of adjunctive involved field (IF) radiotherapy on long-term local control for patients with Ann Arbor Stage I-III diffuse large cell lymphoma (DLCL) who achieved a complete remission on a combined modality program which included cyclophosphamide, doxorubicin, vincristine, prednisone, and Bleomycin (CHOP-Bleo). Methods and Materials: One hundred and ninety patients with Ann Arbor Stage I-III DLCL were treated with CHOP-Bleo and radiotherapy. Analyses were undertaken to determine (a) response to treatment according to stage, extent of maximum local disease, and irradiation dose either < 40 Gy or ≥ 40 Gy and (b) relapse patterns. Results: A complete remission (CR) was achieved in 162 patients. Among patients who achieved a CR, local control was better for those who received tumor doses of ≥ 40 Gy (97%) than for those who received < 40 Gy (83%) (p = 0.002.) Among those with extensive local disease, the corresponding control rates were 88% and 71%, respectively. A study of distant relapse patterns following a CR showed that the first relapse usually involved an extranodal site. Conclusion: Radiotherapy was an effective adjunctive treatment to CHOP-Bleo for patients with stage I-III DLCL who achieved a CR. Patterns of relapse suggested that total nodal irradiation (TNI) possibly could have benefited a small subset of patients

  9. Aberrant expression of the dendritic cell marker TNFAIP2 by the malignant cells of Hodgkin lymphoma and primary mediastinal large B cell lymphoma distinguishes these tumor types from morphologically and phenotypically similar lymphomas

    TNFAIP2 is a protein upregulated in response to TNF signaling but its cellular expression and function in normal and neoplastic tissues remains largely unknown. Here we use standard immunohistochemical techniques to demonstrate that TNFAIP2 is normally expressed by follicular dendritic cells, interdigitating dendritic cells, and macrophages but not by lymphoid cells in secondary lymphoid tissues. Consistent with this expression pattern, we found strong TNFAIP2 staining of tumor cells in 4/4 cases (100%) of follicular dendritic cell sarcoma and in 3/3 cases (100%) of histiocytic sarcoma. Although TNFAIP2 is not expressed by the small and intermediate-size neoplastic B-cells comprising follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma, or marginal zone lymphoma, we observed strong TNFAIP2 staining of the large, neoplastic cells, in 31/31 cases (100%) of classical Hodgkin lymphoma, 12/12 cases (100%) of nodular lymphocyte predominant Hodgkin lymphoma, and 27/31 cases (87%) of primary mediastinal (thymic) large B cell lymphoma. In contrast, TNFAIP2 was expressed by the malignant cells in only 2/45 cases (4%) of diffuse large B cell lymphoma, not otherwise specified, 2/18 cases (11%) of Burkitt lymphoma, and 1/19 cases (5%) of anaplastic large cell lymphoma. Further analysis indicates that TNFAIP2, as a single diagnostic marker, is more sensitive (sensitivity= 87%) and specific (specificity= 96%) than TRAF1, nuclear cRel, or CD23 for distinguishing the malignant B-cells of primary mediastinal (thymic) large B cell lymphoma from those of its morphologic and immunophenotypic mimic, diffuse large B cell lymphoma, not otherwise specified. Thus, TNFAIP2 may serve as a useful new marker of dendritic and histiocytic sarcomas whose aberrant expression in the malignant cells of classical Hodgkin lymphoma and primary mediastinal (thymic) large B cell lymphoma serves to distinguish these tumors from other large cell lymphomas in routine clinical practice.

    Patients with limited-stage Hodgkin lymphoma (HL) undergo frequent posttreatment surveillance CT examinations, raising concerns about the cumulative magnitude of radiation exposure. The purpose of this study was to project radiation-induced cancer risks relative to competing risks of HL and account for the differential timing of each. We adapted a previously developed Markov model to project lifetime mortality risks and life expectancy losses due to HL versus radiation-induced cancers in HL patients undergoing surveillance CT. In the base case, we modeled 35-year-old men and women undergoing seven CT examinations of the chest, abdomen, and pelvis over 5 years. Radiation-induced cancer risks and deaths for 17 organ systems were modeled using an organ-specific approach, accounting for specific anatomy exposed at CT. Cohorts of 20-, 50-, and 65-year-old men and women were evaluated in secondary analyses. Markov chain Monte Carlo methods were used to estimate the uncertainty of radiation risk projections. For 35-year-old adults, we projected 3324/100,000 (men) and 3345/100,000 (women) deaths from recurrent lymphoma and 245/100,000 (men, 95% uncertainty interval [UI]: 121-369) and 317/100,000 (women, 95% UI: 202-432) radiation-induced cancer deaths. Discrepancies in life expectancy losses between HL (428 days in men, 482 days in women) and radiation-induced cancers (11.6 days in men, [95% UI: 5.7-17.5], 15.6 days in women [95% UI: 9.8-21.4]) were proportionately greater because of the delayed timing of radiation-induced cancers relative to recurrent HL. Deaths and life expectancy losses from radiation-induced cancers were highest in the youngest cohorts. Given the low rate of radiation-induced cancer deaths associated with CT surveillance, modest CT benefits would justify its use in patients with limited-stage HL.

    Purpose: Mantle cell lymphoma (MCL) is a rare, albeit aggressive subset of non-Hodgkin lymphoma, resulting in varied treatment approaches. Given the paucity of data defining the optimal management for early-stage MCL, we conducted an analysis using the National Cancer Data Base (NCDB) to identify practice patterns and outcomes. Methods and Materials: The NCDB was queried for patients with stage I to II MCL diagnosed from 1998 to 2012 receiving chemotherapy (CT) or radiation therapy (RT), or both (CT+RT). Univariate and multivariable analyses for factors associated with treatment selection were completed using logistic regression. Propensity scores with inverse probability treatment weighting (IPTW) were calculated based on the conditional probability of receiving CT+RT. The log-rank test and Cox proportional hazards modeling with IPTW adjustment were conducted for the survival analyses. Results: In total, 2539 patients were identified. The key characteristics were as follows: 69% were male, 71% were aged ≥60 years, 28% had extranodal involvement, and 51% had stage I disease. Of the 2539 patients, 70% underwent CT, 11% underwent RT, and 19% underwent CT+RT. The use of CT+RT decreased from 23.1% to 14.1% in 1998 to 2002 and 2010 to 2012 (P<.001). CT+RT usage was lower for patients with the following characteristics: age ≥60 years, female sex, stage II disease, and the presence of B symptoms. With a median follow-up period of 42.8 months, the unadjusted 3-year overall survival estimates for patients receiving CT, RT, or CT+RT were 67.8%, 72.4%, and 79.8%, respectively (P<.001). After correcting for indication bias through IPTW-adjusted modeling, CT+RT reduced the risk of overall mortality compared with monotherapy (hazard ratio 0.65, P=.029). Conclusions: Although uncommon, patients with stage I-II MCL can have favorable outcomes. Despite a continued decline in the usage of consolidative RT, combined modality therapy improves survival in this cohort compared

    FOXP3 is a unique marker for CD4+CD25+ regulatory T cells (Tregs). In solid tumours, high numbers of Tregs are associated with a poor prognosis. Knowledge about the implications of Tregs for the behaviour of haematological malignancies is limited. In this study, skin biopsies from 86 patients...... with mycosis fungoides (MF) and cutaneous T-cell lymphoma (CTCL) unspecified were analysed for the expression of FOXP3 on tumour cells and tumour-infiltrating Tregs. Labelling of above 10% of the neoplastic cells was seen in one case classified as an aggressive epidermotropic CD8+ cytotoxic CTCL....... In the remaining 85 cases, the atypical neoplastic infiltrate was either FOXP3 negative (n=80) or contained only very occasional weakly positive cells (n=5). By contrast, all biopsies showed varying numbers of strongly FOXP3+ tumour-infiltrating Tregs. MF with early or infiltrated plaques had significantly higher...

    Full Text Available Abstract Background Cure rate of early Hodgkin Lymphoma are high and avoidance of late toxicities is of paramount importance. This comparative study aims to assess the normal tissue sparing capability of intensity-modulated radiation therapy (IMRT versus standard three-dimensional conformal radiotherapy (3D-CRT in terms of dose-volume parameters and normal tissue complication probability (NTCP for different organs at risk in supradiaphragmatic Hodgkin Lymphoma (HL patients. Methods Ten HL patients were actually treated with 3D-CRT and all treatments were then re-planned with IMRT. Dose-volume parameters for thyroid, oesophagus, heart, coronary arteries, lung, spinal cord and breast were evaluated. Dose-volume histograms generated by TPS were analyzed to predict the NTCP for the considered organs at risk, according to different endpoints. Results Regarding dose-volume parameters no statistically significant differences were recorded for heart and origin of coronary arteries. We recorded statistically significant lower V30 with IMRT for oesophagus (6.42 vs 0.33, p = 0.02 and lungs (4.7 vs 0.1 p = 0.014 for the left lung and 2.59 vs 0.1 p = 0.017 for the right lung and lower V20 for spinal cord (17.8 vs 7.2 p = 0.02. Moreover the maximum dose to the spinal cord was lower with IMRT (30.2 vs 19.9, p Conclusions In HL male patients IMRT seems feasible and accurate while for women HL patients IMRT should be used with caution.

    Lymphomas are classified based on the normal counterpart, or cell of origin, from which they arise. Because lymphocytes have physiologic immune functions that vary both by lineage and by stage of differentiation, the classification of lymphomas arising from these normal lymphoid populations is complex. Recent genomic data have contributed additional complexity. Areas covered: Lymphoma classification follows the World Health Organization (WHO) system, which reflects international consensus and is based on pathological, genetic, and clinical factors. A 2016 revision to the WHO classification of lymphoid neoplasms recently was reported. The present review focuses on B-cell non-Hodgkin lymphomas, the most common group of lymphomas, and summarizes recent changes most relevant to hematologists and other clinicians who care for lymphoma patients. Expert commentary: Lymphoma classification is a continually evolving field that needs to be responsive to new clinical, pathological, and molecular understanding of lymphoid neoplasia. Among the entities covered in this review, the 2016 revision of the WHO classification particularly impact the subclassification and genetic stratification of diffuse large B-cell lymphoma and high-grade B-cell lymphomas, and reflect evolving criteria and nomenclature for indolent B-cell lymphomas and lymphoproliferative disorders.

    The purpose of the study was to determine in human malignant lymphomas the expression patterns of nicotinamide phosphoribosyltransferase (NAMPT) and nicotinic acid phosphoribosyltransferase (NAPRT), the primary, rate-limiting enzymes in the synthesis of NAD+. NAMPT is a potential biomarker for sensitivity to NAMPT inhibitors and NAPRT is a biomarker for the use of nicotinic acid as a chemoprotectant in treatment with NAMPT inhibitors. The NAMPT inhibitor, APO866, is currently in clinical phase II trials in lymphomas. The expression of NAMPT and NAPRT was investigated in 53 samples of malignant lymphomas (diffuse large B-cell lymphoma, follicular B-cell lymphoma, Hodgkin's lymphoma and peripheral T-cell lymphoma). The expression of NAMPT was generally high in the more aggressive malignant lymphomas, with >80% strong expression, whereas the expression in the more indolent follicular lymphoma (FL) was significantly lower (>75% moderate or low expression, p = 0.0002). NAMPT was very highly expressed in Hodgkin Reed-Sternberg cells in Hodgkin's lymphoma. NAPRT expression was more varied (p > 0.0001) with 30-50% low expression except for Hodgkin's lymphoma where 85% displayed low expression (p = 0.0024). In conclusion, FL are a promising target for NAMPT inhibitors whereas substantial subsets of malignant lymphomas especially in Hodgkin lymphoma may be suitable for a combination treatment with nicotinic acid and NAMPT inhibitors. © 2011 The Authors.

    This study seeks to investigate the long-term public health burden of Hodgkin lymphoma (HL) in terms of work loss following contemporary treatment protocols and associations with established treatment complications and lymphoma relapse. We identified 1,989 Swedish HL patients (1,082 with clinical information) aged 18-60 (median 33) years at diagnosis 1992-2009, and matched 1:4 to population comparators. Sick leave, disability pension (work loss), and comorbidity were retrieved through September 2013. Relative risks (RR) with 95% confidence intervals (CI) were calculated using Poisson regression, and mean lost work days were estimated yearly during follow-up. The risk of annual work loss was elevated in HL survivors versus comparators up to the 15th year post-diagnosis (RR(5th year) 1.64, 95% CI 1.46-1.84; RR(10th year) 1.33, 95% CI 1.15-1.34; and RR(15th year) 1.30, 95% CI 1.04-1.62). The risk remained elevated up to the 10th year after adjustment for secondary malignancies and cardiovascular disease (RR(10th year) 1.31, 95% CI 1.13-1.52). Advanced-stage patients had more lost days than comparators (mean number(5th year) 66 versus 33, mean difference 34, 95% CI 20-48) as did patients receiving 6-8 chemotherapy courses (62 versus 33, mean difference(5th year) 30, 95 % CI 17-43). Among patients in the first complete remission, a difference was still observed for advanced-stage (51 versus 33, mean difference(5th year) 19, 95% CI 5-34) but not early-stage disease. Advanced-stage HL survivors treated with full-dose chemotherapy were at increased risk of work loss, not only explained by relapse, secondary malignancies, or cardiovascular disease. The results call for increased awareness and evaluation of reasons for long-term work disability following intensive chemotherapy among young HL survivors.

    Primary gastric lymphomas are the most common extra nodal lymphomas. They can be presented as aggressive or indolent, majority of indolent lymphomas are associated to H. pylori infection. The basic diagnostic procedures are endoscopy, endo sonography and biopsy of gastric tissue. Therapy is related to the histological subtype, stage, H. pylori positivity, clinical symptoms and condition of patient. The aim of the treatment is remission as well as good quality of life. The prognosis of patients with primary gastric lymphomas is relatively good. (author)

    Purpose: To evaluate the dosimetric and clinical outcomes of involved-field intensity-modulated radiotherapy (IF-IMRT) for patients with early-stage Hodgkin's lymphoma (HL) with mediastinal involvement. Methods and Materials: Fifty-two patients with early-stage HL that involved the mediastinum were reviewed. Eight patients had Stage I disease, and 44 patients had Stage II disease. Twenty-three patients (44%) presented with a bulky mediastinum, whereas 42 patients (81%) had involvement of both the mediastinum and either cervical or axillary nodes. All patients received combination chemotherapy followed by IF-IMRT. The prescribed radiation dose was 30-40 Gy. The dose-volume histograms of the target volume and critical normal structures were evaluated. Results: The median mean dose to the primary involved regions (planning target volume, PTV1) and boost area (PTV2) was 37.5 Gy and 42.1 Gy, respectively. Only 0.4% and 1.3% of the PTV1 and 0.1% and 0.5% of the PTV2 received less than 90% and 95% of the prescribed dose, indicating excellent PTV coverage. The median mean lung dose and V20 to the lungs were 13.8 Gy and 25.9%, respectively. The 3-year overall survival, local control, and progression-free survival rates were 100%, 97.9%, and 96%, respectively. No Grade 4 or 5 acute or late toxicities were reported. Conclusions: Despite the large target volume, IF-IMRT gave excellent dose coverage and a favorable prognosis, with mild toxicity in patients with early-stage mediastinal HL.

    Purpose: The purpose of this study was to evaluate the role of involved-lesion radiation therapy (ILRT) after rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy in limited stage diffuse large B-cell lymphoma (DLBCL) by comparing outcomes of R-CHOP therapy alone with R-CHOP followed by ILRT. Methods and Materials: We identified 198 patients treated with R-CHOP (median, 6 cycles) for pathologically confirmed DLBCL of limited stage from July 2004 to December 2012. Clinical characteristics of these patients were 33% with stage I and 66.7% with stage II; 79.8% were in the low or low-intermediate risk group; 13.6% had B symptoms; 29.8% had bulky tumors (≥7 cm); and 75.3% underwent ≥6 cycles of R-CHOP therapy. RT was given to 43 patients (21.7%) using ILRT technique, which included the prechemotherapy tumor volume with a median margin of 2 cm (median RT dose: 36 Gy). Results: After a median follow-up of 40 months, 3-year progression-free survival (PFS) and overall survival (OS) were 85.8% and 88.9%, respectively. Multivariate analysis showed ≥6 cycles of R-CHOP (PFS, P=.004; OS, P=.004) and ILRT (PFS, P=.021; OS, P=.014) were favorable prognosticators of PFS and OS. A bulky tumor (P=.027) and response to R-CHOP (P=.012) were also found to be independent factors of OS. In subgroup analysis, the effect of ILRT was prominent in patients with a bulky tumor (PFS, P=.014; OS, P=.030) or an elevated level of serum lactate dehydrogenase (LDH; PFS, P=.004; OS, P=.012). Conclusions: Our results suggest that ILRT after R-CHOP therapy improves PFS and OS in patients with limited stage DLBCL, especially in those with bulky disease or an elevated serum LDH level.

  4. Genetic variation in DNA repair pathways and risk of non-Hodgkin's lymphoma.

    Justin Rendleman

    Full Text Available Molecular and genetic evidence suggests that DNA repair pathways may contribute to lymphoma susceptibility. Several studies have examined the association of DNA repair genes with lymphoma risk, but the findings from these reports have been inconsistent. Here we provide the results of a focused analysis of genetic variation in DNA repair genes and their association with the risk of non-Hodgkin's lymphoma (NHL. With a population of 1,297 NHL cases and 1,946 controls, we have performed a two-stage case/control association analysis of 446 single nucleotide polymorphisms (SNPs tagging the genetic variation in 81 DNA repair genes. We found the most significant association with NHL risk in the ATM locus for rs227060 (OR = 1.27, 95% CI: 1.13-1.43, p = 6.77×10(-5, which remained significant after adjustment for multiple testing. In a subtype-specific analysis, associations were also observed for the ATM locus among both diffuse large B-cell lymphomas (DLBCL and small lymphocytic lymphomas (SLL, however there was no association observed among follicular lymphomas (FL. In addition, our study provides suggestive evidence of an interaction between SNPs in MRE11A and NBS1 associated with NHL risk (OR = 0.51, 95% CI: 0.34-0.77, p = 0.0002. Finally, an imputation analysis using the 1,000 Genomes Project data combined with a functional prediction analysis revealed the presence of biologically relevant variants that correlate with the observed association signals. While the findings generated here warrant independent validation, the results of our large study suggest that ATM may be a novel locus associated with the risk of multiple subtypes of NHL.

    Full Text Available BACKGROUND: 2-[18F]-Fluoro-2-Deoxy-D-Glucose (FDG-PET is a well established functional imaging modality for the initial staging of Hodgkin lymphoma (HL in patients from Western Europe and North America. The reliability of FDG-PET in populations of different ethnic groups is unclear, as all investigations published to date have come from developed countries. PURPOSE: The aim of the present study was to investigate the effectiveness of FDG-PET in the initial staging of HL patients in a Brazilian population. METHODS: Eighty-two patients with newly diagnosed HL were prospectively included in the study. All patients were staged with both conventional clinical staging (CCS methods, including computed tomography (CT and whole-body FDG-PET methods. A standard of reference for the nodal regions and the extranodal organs was determined using all available information, including the CCS methods, FDG-PET, the diagnostic histology and the follow-up examinations. The results of the CCS were then compared to the FDG-PET results. RESULTS: The sensitivity of FDG-PET was higher for nodal staging than that of CT (87.8% vs. 61.6%, respectively. FDG-PET was also more sensitive than CT in regard to evaluating the extranodal organs for lymphomatous involvement (96.2% vs. 40.0%, respectively. FDG-PET detected all 16 patients who were characterized by a positive bone marrow biopsy and identified an additional 4 patients with bone marrow disease. The incorporation of FDG-PET coupled with CCS in the staging procedure upstaged 20% (17/82 of the patients and downstaged 11% (9/82 of the patients. As a result of these changes in staging, 15% (13/82 of the patients would have received a different therapeutic regimen. CONCLUSIONS: The FDG-PET method is superior to CT for the detection of nodal and extra-nodal HL. The observation that the FDG-PET method upstaged the disease was the most common result (20% of patients brought about by the addition of PET to the staging algorithm

    interim PET imaging has high prognostic value in lymphoma, a number of trials investigate PET-based, response-adapted therapy for non-Hodgkin lymphomas (NHL). PET response is the main determinant of response according to the new response criteria, but PET/CT has little or no role in routine surveillance......Optimal lymphoma management requires accurate pretreatment staging and reliable assessment of response, both during and after therapy. Positron emission tomography with computerized tomography (PET/CT) combines functional and anatomical imaging and provides the most sensitive and accurate methods...... for lymphoma imaging. New guidelines for lymphoma imaging and recently revised criteria for lymphoma staging and response assessment recommend PET/CT staging, treatment monitoring, and response evaluation in all FDG-avid lymphomas, while CT remains the method of choice for non-FDG-avid histologies.

    Lymphoma is the most common hematologic malignancy and represents approximately 5.3% of all cancers. The World Health Organization published a revised classification scheme in 2008 that groups lymphomas by cell type and molecular, cytogenetic, and phenotypic characteristics. Most lymphomas affect the thorax at some stage during the course of the disease. Affected structures within the chest may include the lungs, mediastinum, pleura, and chest wall, and lymphomas may originate from these sites as primary malignancies or secondarily involve these structures after arising from other intrathoracic or extrathoracic sources. Pulmonary lymphomas are classified into one of four types: primary pulmonary lymphoma, secondary pulmonary lymphoma, acquired immunodeficiency syndrome-related lymphoma, and post-transplantation lymphoproliferative disorders. Although pulmonary lymphomas may produce a myriad of diverse findings within the lungs, specific individual features or combinations of features can be used, in combination with secondary manifestations of the disease such as involvement of the mediastinum, pleura, and chest wall, to narrow the differential diagnosis. While findings of thoracic lymphoma may be evident on chest radiography, computed tomography has traditionally been the imaging modality used to evaluate the disease and effectively demonstrates the extent of intrathoracic involvement and the presence and extent of extrathoracic spread. However, additional modalities such as magnetic resonance imaging of the thorax and 18 F-FDG PET/CT have emerged in recent years and are complementary to CT in the evaluation of patients with lymphoma. Thoracic MRI is useful in assessing vascular, cardiac, and chest wall involvement, and PET/CT is more accurate in the overall staging of lymphoma than CT and can be used to evaluate treatment response

While findings of thoracic lymphoma may be evident on chest radiography, computed tomography has traditionally been the imaging modality used to evaluate the disease and effectively demonstrates the extent of intrathoracic involvement and the presence and extent of extrathoracic spread. However, additional modalities such as magnetic resonance imaging of the thorax and {sup 18}F-FDG PET/CT have emerged in recent years and are complementary to CT in the evaluation of patients with lymphoma. Thoracic MRI is useful in assessing vascular, cardiac, and chest wall involvement, and PET/CT is more accurate in the overall staging of lymphoma than CT and can be used to evaluate treatment response.

    The diagnosis of follicular dendritic cell (FDC) sarcoma can be challenging because of its morphologic overlaps with many other spindle cell neoplasms and, therefore, new phenotypic markers will be helpful in its differential diagnosis. Podoplanin is a mucin-type transmembrane glycoprotein that has recently been detected in reactive FDCs. In this study, we investigated the expression patterns of podoplanin using a new mouse monoclonal antibody D2-40, and compared them with CD21, a well-established FDC marker, in a comprehensive panel of cases. The panel included 4 FDC sarcomas, 38 spindle cell neoplasms of other types, 25 reactive lymphoid hyperplasia, and 117 lymphoid and 5 myeloid malignant hematopoietic neoplasms. Our study revealed that D2-40 strongly stained 3 of 4 FDC sarcomas. In contrast, D2-40 stained only 2/38 other spindle cell neoplasms tested. Furthermore, we observed that D2-40 highlighted more FDC meshworks than CD21 in Castleman's disease, follicular lymphoma, nodular lymphocyte predominance Hodgkin lymphoma, and residual reactive germinal centers in a variety of lymphoma types. D2-40 and CD21 stained an equal number of cases of reactive lymphoid hyperplasia, progressively transformed germinal centers and angioimmunoblastic T-cell lymphoma. No expression of podoplanin was detected in normal or neoplastic lymphoid and myeloid cells. We conclude that podoplanin (D2-40) is a sensitive and specific FDC marker, which is superior or equal to CD21 in evaluating both reactive and neoplastic FDCs. In addition, our results suggest that podoplanin (D2-40) can be used to support the diagnosis of FDC sarcoma. PMID:18784810

    Primary vitreoretinal lymphoma (PVRL) is the most common intraocular lymphoma. It is a high grade malignant B‑cell lymphoma, which is thought to arise in the retina. It often infiltrates the central nervous system (CNS) and is therefore associated with a poor prognosis. The PVRL must be differentiated from other forms of intraocular lymphoma, such as the low-grade B‑cell lymphoma that rarely arises in the choroid. The choroidal lymphomas do not spread to the brain, they can be treated with low-dose external beam radiotherapy and the patients have a good prognosis. Since PVRL is a relatively rare tumor, there is little information with respect to its true incidence, to any geographical or ethnic variability and to the main risk factors apart from an association with immunosuppression, as a result of HIV or Epstein-Barr virus infections. The treatment of PVRL is very variable between oncology centres and is also dependent on the unilaterality or bilaterality of disease and whether there is any concomitant CNS involvement. Further studies and research projects in this field are necessary in order to diagnose PVRL at an early stage and to develop new targeted individualized treatment.

    It has been hypothesized that defects in DNA-mismatch repair are associated with smoking in certain types of transformed non-Hodgkin lymphoma (NHL). We have analyzed biopsy samples from two indolent B-cell lymphomas, follicular lymphoma (FL) and chronic lymphocytic leukemia/small lymphocytic...... leukemia (CLL/SLL), that have transformed to diffuse-large B-cell lymphoma (DLBCL). We correlated the presence or absence of DNA-mismatch repair enzymes by immunostaining as well as the p53 status to smoking history. Of all patients (n = 30), 37% showed negative immunostaining of MLH1, 16% showed negative...... of transformed lymphomas through defective mismatch repair....

    Endemic Burkitt lymphoma (eBL) is linked to Plasmodium falciparum (Pf) infection geographically, but evidence from individual-level studies is limited. We investigated this issue among 354 childhood eBL cases and 384 age-, sex-, and location-matched controls enrolled in Ghana from 1965 to 1994. Immunoglobulin G1 (IgG1) and immunoglobulin G3 (IgG3) antibodies to antigens diagnostic of recent infection Pf histidine-rich protein-II (HRP-II) and 6NANP, Pf-vaccine candidates SE36 and 42-kDa region of the 3D7 Pf merozoite surface protein-1 (MSP-1), and tetanus toxoid were measured by indirect enzyme-linked immunoassay. Odds ratios (ORs) and 95% confidence intervals (CIs) for association with eBL were estimated using unconditional logistic regression. After adjustments, eBL was positively associated with HRP-IIIgG3 seropositivity (adjusted OR: 1.60; 95% CI 1.08-2.36) and inversely associated with SE36IgG1 seropositivity (adjusted OR: 0.37; 95% CI 0.21-0.64) and with tetanus toxoidIgG3 levels equal or higher than the mean (adjusted OR: 0.46; 95% CI 0.32-0.66). Anti-MSP-1IgG3 and anti-6NANPIgG3 were indeterminate. eBL risk was potentially 21 times higher (95% CI 5.8-74) in HRP-IIIgG3-seropositive and SE36IgG1-seronegative responders compared with HRP-IIIgG3-seronegative and SE36IgG1-seropositive responders. Our results suggest that recent malaria may be associated with risk of eBL but long-term infection may be protective.

    Lymphomas infiltrating the mediastinum are a challenge for the treating physician as well as for the pathological diagnostics. The clinical scenario is often an emergency situation, while the pathologist is usually confronted only with small biopsy samples. Classical Hodgkin's lymphoma is by far the most frequently occurring lymphoma in the mediastinum and predominantly the nodular sclerosis subtype. In small and very sclerotic specimens it can be difficult to morphologically detect Hodgkin and Reed-Sternberg cells and to identify the characteristic phenotype by immunohistochemistry. Primary mediastinal large B‑cell lymphomas should be distinguished from classical Hodgkin's lymphomas as the treatment is different. This is characterized by the detection of sheets of blast cells, which immunohistochemically show a strong B‑cell phenotype (positivity for CD20 and CD79a), while CD30 can also often be expressed. The intimate biological relationship between classical Hodgkin's lymphomas and mediastinal large B‑cell lymphomas is illustrated by the existence of B‑cell lymphomas with intermediate features (so-called mediastinal grey zone lymphomas). It is important to recognize and diagnose these lymphomas as they are associated with a slightly inferior prognosis. Extranodal thymic marginal zone lymphomas of the mucosa-associated lymphoid tissue (MALT) type are a rare form of lymphoma encountered in the mediastinum, which can be associated with autoimmune diseases. T‑lymphoblastic lymphomas and leukemia, which occur predominantly in children and young adults, represent a rapidly growing precursor cell neoplasia and must be distinguished from thymomas in the differential diagnostics as well as from normal and hyperplastic thymus glands.

    Purpose: In early-stage classical Hodgkin lymphoma, fluorodeoxyglucose positron emission tomography (PET)-computed tomography (CT) scans are performed routinely after chemotherapy, and the 5-point Deauville score is used to report the disease response. We hypothesized that other PET-CT parameters, considered in combination with Deauville score, would improve risk stratification. Methods and Materials: Patients treated for stage I to II Hodgkin lymphoma from 2003 to 2013, who were aged ≥18 years and had analyzable PET-CT scans performed before and after chemotherapy, were eligible. The soft tissue volume (STV), maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis were recorded from the PET-CT scans before and after chemotherapy. Reductions were defined as 1 − (final PET-CT value)/(corresponding initial PET-CT value). The primary endpoint was freedom from progression (FFP). Results: For 202 patients treated with chemotherapy with or without radiation therapy, the 5-year FFP was 89% (95% confidence interval 85%-93%). All PET-CT parameters were strongly associated with the Deauville score (P<.001) and FFP (P<.0001) on univariate analysis. The Deauville score was highly predictive of FFP (C-index 0.89) but was less discriminating in the Deauville 1 to 4 subset (C-index 0.67). Therefore, we aimed to identify PET-CT parameters that would improve risk stratification for this subgroup (n=187). STV reduction was predictive of outcome (C-index 0.71) and was dichotomized with an optimal cutoff of 0.65 (65% reduction in STV). A model incorporating the Deauville score and STV reduction predicted FFP more accurately than either measurement alone in the Deauville 1 to 4 subset (C-index 0.83). The improvement in predictive accuracy of this composite measure compared with the Deauville score alone met statistical significance (P=.045). Conclusions: The relative reduction in tumor size is an independent predictor of outcome. Combined with the

    Treatment options for patients with nonbulky stage IA-IIA Hodgkin lymphoma include combined modality therapy (CMT) using doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) plus involved-field radiation therapy (IFRT), and chemotherapy with ABVD alone. There are no mature randomized data comparing ABVD with CMT using modern radiation techniques. Using German Hodgkin Study Group HD10/HD11 and NCIC Clinical Trials Group HD.6 databases, we identified 588 patients who met mutually inclusive eligibility criteria from the preferred arms of HD10 or 11 (n = 406) and HD.6 (n = 182). We evaluated time to progression (TTP), progression-free (PFS) and overall survival, including in three predefined exploratory subset analyses. With median follow-up of 91 (HD10/11) and 134 (HD.6) months, respective 8-year outcomes were for TTP, 93% versus 87% [hazard ratio (HR) 0.44, 95% confidence interval (CI) 0.24-0.78]; for PFS, 89% versus 86% (HR 0.71, 95% CI 0.42-1.18) and for overall survival, 95% versus 95% (HR 1.09, 95% CI 0.49-2.40). In the exploratory subset analysis including HD10 eligible patients who achieved complete response (CR) or unconfirmed complete response (CRu) after two cycles of ABVD, 8-year PFS was 87% (HD10) versus 95% (HD.6) (HR 2.8; 95% CI 0.64-12.5) and overall survival 96% versus 100%. In contrast, among those without CR/CRu after two cycles of ABVD, 8-year PFS was 88% versus 74% (HR 0.35; 95% CI 0.16-0.79) and overall survival 95% versus 91%, respectively (HR 0.42; 95% CI 0.12-1.44). In patients with nonbulky stage IA-IIA Hodgkin lymphoma, CMT provides better disease control than ABVD alone, especially among those not achieving complete response after two cycles of ABVD. Within the follow-up duration evaluated, overall survivals were similar. Longer follow-up is required to understand the implications of radiation and chemotherapy-related late effects. The trials included in this analysis were registered at ClinicalTrials.gov: HD10 - NCT00265018, HD11

    The role of radiotherapy in the treatment of nodal non-Hodgkin's lymphoma has been modified by the introduction of efficient chemotherapy and the development of different pathological classifications. The recommended treatment of early-stage aggressive lymphomas is primarily a combination chemotherapy. The interest of adjuvant radiotherapy remains unclear and has to be established through large prospective trials. If radiation therapy has to be delivered, the historical results of exclusive radiation therapy showed that involved-fields and a dose of 35-40 Gy (daily fraction of 1.8 Gy, 5 days a week) are the optimal schedule. The interest of radiotherapy in the treatment of advanced-stage aggressive lymphoma is yet to be proven. Further studies had to stratify localized stages according to the factors of the International Prognostic Index. For easy-stage low-grade lymphoma, radiotherapy remains the standard treatment. However, the appropriate technique to use is controversial. Involved-field irradiation at a dose of 35 Gy seems to be the optimal schedule, providing a 10 year disease-free survival rate of 50 % and no major toxicity. There is no standard indication of radiotherapy in the treatment advanced-stage low-grade lymphoma. For 'new' nodal lymphoma's types, the indication of radiotherapy cannot be established (mantle-zone lymphoma, marginal zone B-cell lymphoma) or must take into account the natural history (Burkitt's lymphoma, peripheral T-cell lymphoma) and the sensibility to others therapeutic methods.

    Purpose: The German Hodgkin Study Group HD11 trial validated 4 cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy followed by involved field radiation therapy (IFRT) for early unfavorable Hodgkin lymphoma (HL) patients. However, practitioners often recommend 6 cycles followed by RT, especially for bulky disease. We compared patient outcomes after treatment with 4 or 6 cycles of ABVD followed by RT (IFRT and involved site RT [ISRT]). Methods and Materials: We identified 128 patients treated for early unfavorable HL (GHSG criteria) between 2000 and 2013. Clinical outcomes (overall survival [OS] and freedom from relapse [FFR]) were estimated using Kaplan-Meier analysis. Toxicities were evaluated. Results: The median follow-up time was 5.0 years. Patients received 4 (70 patients, 55%) or 6 (58 patients, 45%) cycles of chemotherapy. Bulky disease was present in 22 patients (31%; 0 stage IA, 3 stage IB, 19 stage IIA) of the 4-cycle group and 42 patients (72%; 5 stage IA, 3 stage IB, 34 stage IIA) of the 6-cycle group. For patients receiving 4 and 6 cycles, the 6-year OS was 100% and 97% (P=.35), respectively, and the 6 year FFR was 100% and 98% (P=.28), respectively. More patients received 6 cycles if they were treated before 2010 (HD11 report) (P=.01) and if they had bulky disease (P<.01). Sixty-eight percent of patients received ISRT. The 6-year FFR was 99% and 100% for patients receiving ISRT and IFRT, respectively (P=.58). More patients experienced bleomycin pulmonary toxicity in the 6-cycle group (20% vs 31%, P=.16). For patients with bulky disease, the 4-year FFR was similar with receipt of 4 (100%) or 6 (98%) cycles (P=.48) and IFRT (100%) or ISRT (98%) (P=.52). There were no deaths among patients with bulky disease. Conclusions: Patients with early unfavorable HL have excellent outcomes with 4 cycles of ABVD chemotherapy followed by ISRT. Six cycles of chemotherapy does not appear superior for disease control, even for bulky disease.

    Full Text Available Follicular mucinosis occurring along with angiolymphoid hyperplasia with eosinophils (ALHE has been described in a 54-year-old female. The patient presented with pruritic erythematous papules on the left frontoparietal scalp. Histopathological examination showed prominent blood vessels in the dermis lined by plump histiocytoid endothelial cells that were surrounded by a dense lymphoid infiltrate with numerous eosinophils; these findings are typical of angiolymphoid hyperplasia with eosinophils. Features of follicular mucinosis were observed in the same section with several hyperplastic follicular infundibula containing pools of mucin in the infundibular epithelium. The concurrent occurrence of these two distinct histopathological patterns in the same biopsy specimen has been described in only three cases to date.

    Improvements in the classification, staging, and treatment of the lymphomas, complemented by an improved understanding of the biology of these diseases, has led to an improved outcome of therapy for both Hodgkin's disease and many of the non-Hodgkin's lymphomas. The rapid changes that have occurred in this field in the last decade make it timely to review this subject for radiation oncologists in a comprehensive fashion. This course is designed to meet broad educational needs required for understanding these diseases and providing effective care for patients with lymphoma. The faculty includes many leaders from both laboratory and clinical disciplines dealing with lymphomas, who will address a variety of scientific and clinical topics. The morning session will be devoted to Hodgkin's disease, including new concepts in its biology, a review of clinical trials for early stage disease, a discussion of the role of high dose therapy, and description of long term complications of treatment. The afternoon sessions will be devoted to the non-Hodgkin's lymphomas, including new concepts in pathology and biology, a description of specific entities including the low grade lymphomas, MALT lymphomas, extranodal lymphomas, intermediate grade lymphomas, mantle cell lymphomas, and summary discussions of the role of radioimmuno-therapy and high dose therapy. Although the role of radiation therapy in the management of patients with lymphoma has changed dramatically in the past two decades, radiation remains the most effective single agent for the treatment of these diseases and it is especially important for radiation onologists to keep abreast of these new concepts. This course has been designed to achieve that goal

    The enhanced early embryonic survival in Chinese Meishan compared with Large-White gilts may be due, in part, to differences in ovarian and endocrine function, particularly during the periovulatory period. The overall patterns of oestradiol, LH and FSH secretion were not different between Meishan and Large-White hybrid controls during this period, although circulating inhibin concentrations were higher in Meishan gilts. Thus, there appeared to be a decreased sensitivity to inhibin feedback on FSH secretion in Meishan gilts. Behavioural oestrus was exhibited earlier relative to the LH surge in Meishan gilts than in Large-White hybrid gilts, but the time interval from the oestradiol peak until the LH surge was similar in both breeds. This finding suggests that Meishan gilts are more sensitive in terms of initiating a behavioural response, but not in terms of positive feedback. Although preovulatory follicular characteristics were as variable in Meishan as in Large-White hybrid gilts, follicles from Meishan gilts were smaller, but contained a higher concentration of oestradiol in the follicular fluid. This was probably due to increased aromatase activity in both granulosa and theca cells of Meishan follicles. The enhanced maturation of the intrafollicular environment in Meishan gilts was reflected in the oocyte population which was at a more advanced stage of development in the period preceding ovulation. In addition to decreasing the time between onset of oestrus and ovulation, advancing the LH surge to coincide with onset of oestrus (via hCG administration) decreased embryo survival at day 30 of gestation. It is concluded that both endocrine and follicular mechanisms have a role in ensuring the prolificacy in the Meishan breed.

    Intestinal marginal zone B-cell lymphoma of the MALT type (I-MZL) is a relatively uncommon form of lymphoma. Twenty-seven patients with histologically-confirmed I-MZL were analyzed. The patients initially presented with abdominal pain (62.9%), and diarrhea (22.2%). The most common involved site was the ileo-caecal area (40.7%). Musshoff's stage I(E), II(E)1, II(E)2, III(E) and IV were present in 44%, 15%, 11%, 7.4% and 22% respectively. Sixty-three percent were in the low-risk group according to the Follicular Lymphoma International Prognostic Index. Complete response and partial response were achieved in 82% and 4% patients. The estimated 5-year overall survival (OS) and progression-free survival (PFS) rates were 86% and 54%. Stage > or = II(E)2 was determined to be a poor prognostic factor for PFS and OS. I-MZL commonly manifests in an early-stage, low-risk state and tends to respond well to local and systemic treatment with favorable prognosis. I-MZL tends to be an indolent disease - characterized by prolonged survival with frequent relapses, similarly to other site MZLs.

    Background: The role of surveillance studies in limited-stage diffuse large B-cell lymphoma (DLBCL) in the rituximab era has not been well defined. We sought to evaluate the use of imaging (computed tomography [CT] and positron emission tomography [PET]-CT) scans and lactate dehydrogenase (LDH) in surveillance of patients with stage I to II DLBCL. Methods: A retrospective analysis was performed of patients who received definitive treatment between 2000 and 2013. Results: One hundred sixty-two consecutive patients with stage I to II DLBCL were treated with chemotherapy +/− rituximab, radiation, or combined modality therapy. The 5-year rates of overall survival (OS) and freedom from progression (FFP) were 81.2% and 80.8%, respectively. Of the 162 patients, 124 (77%) were followed up with at least 1 surveillance PET scan beyond end-of-treatment scans; of those, 94 of 124 (76%) achieved a complete metabolic response on PET scan after completion of chemotherapy, and this was associated with superior FFP (P=.01, HR=0.3) and OS (P=.01, HR 0.3). Eighteen patients experienced relapse after initial response to therapy. Nine relapses were initially suspected by surveillance imaging studies (8 PET, 1 CT), and 9 were suspected clinically (5 by patient-reported symptoms and 4 by symptoms and physical examination). No relapses were detected by surveillance LDH. The median duration from initiation of treatment to relapse was 14.3 months among patients with relapses suspected by imaging, and 59.8 months among patients with relapses suspected clinically (P=.077). There was no significant difference in OS from date of first therapy or OS after relapse between patients whose relapse was suspected by imaging versus clinically. Thirteen of 18 patients underwent successful salvage therapy after relapse. Conclusions: A complete response on PET scan immediately after initial chemotherapy is associated with superior FFP and OS in stage I to II DLBCL. The use of PET scans as

Early-stage HL with mediastinal and supraclavicular involvement was studied using an Alderson phantom. A whole body CT was performed and all tissues were delineated. The clinical target volumes and planning target volumes (PTV) were determined according to the German Hodgkin study group guidelines. Free-breathing (FB) technique and DI technique were simulated by different safety margins for the PTV definition. In both cases, 30 Gy in 15 fractions was prescribed. Second cancer risk was estimated for various tissues with a second cancer model including fractionation. When compared with FB-3DCRT, estimated relative life time attributable risk (LAR) of cancer induction after DI-3DCRT was 0.86, 0.76, 0.94 and 0.92 for breast, lung, esophagus and stomach, respectively. With DI-VMAT, the corresponding values were 2.05, 1.29, 1.01, 0.93, respectively. For breast cancer, the LAR observed with DI-VMAT was not substantially distinguishable from the LAR computed for mantle RT with an administered dose of 40 Gy. This study suggests that DI may reduce the LAR of secondary cancers of all OARs and may be a valuable technique when using 3DCRT. Conversely, VMAT may increase substantially the LAR and should be cautiously implemented in clinical practice.

    Full Text Available Primary non-Hodgkins lymphoma of the uterine cervix is a very rare diagnosis. A 54-year-old woman presented with a 3-month history of postmenopausal bleeding per vaginum. On examination, a friable, fungating lesion was seen on the cervix. Histology revealed a CD 20 positive high-grade non-Hodgkin’s diffuse large B cell lymphoma from cervical biopsies and endometrial curettage. She was diagnosed as stage IE after workup and subsequently treated with six cycles of R-CHOP chemotherapy followed by radiotherapy of the involved field.

    2015-11-01

    Hodgkin lymphoma is a rare B-cell malignant neoplasm affecting approximately 9000 new patients annually. This disease represents approximately 11% of all lymphomas seen in the United States and comprises 2 discrete disease entities--classical Hodgkin lymphoma and nodular lymphocyte-predominant Hodgkin lymphoma. Within the subcategorization of classical Hodgkin lymphoma are defined subgroups: nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich Hodgkin lymphoma. Staging of this disease is essential for the choice of optimal therapy. Prognostic models to identify patients at high or low risk for recurrence have been developed, and these models, along with positron emission tomography, are used to provide optimal therapy. The initial treatment for patients with Hodgkin lymphoma is based on the histologic characteristics of the disease, the stage at presentation, and the presence or absence of prognostic factors associated with poor outcome. Patients with early-stage Hodgkin lymphoma commonly receive combined-modality therapies that include abbreviated courses of chemotherapy followed by involved-field radiation treatment. In contrast, patients with advanced-stage Hodgkin lymphoma commonly receive a more prolonged course of combination chemotherapy, with radiation therapy used only in selected cases. For patients with relapse or refractory disease, salvage chemotherapy followed by high-dose treatment and an autologous stem cell transplant is the standard of care. For patients who are ineligible for this therapy or those in whom high-dose therapy and autologous stem cell transplant have failed, treatment with brentuximab vedotin is a standard approach. Additional options include palliative chemotherapy, immune checkpoint inhibitors, nonmyeloablative allogeneic stem cell transplant, or participation in a clinical trial testing novel agents.

    Purpose: To evaluate the dosimetric superiority, efficacy, toxicity, and quality of life (QOL) data of intensity modulated radiation therapy (IMRT) in patients with primary gastric diffuse large B-cell lymphoma (PG-DLBCL). Methods and Materials: Forty-six consecutive patients with early-stage PG-DLBCL underwent IMRT after chemotherapy. The majority of patients (61.5%) were subclassified as the non-germinal center B cell–like subtype. Dosimetric parameters of the planning target volume (PTV) and organs at risk were assessed. Survival rates were depicted with the Kaplan-Meier method and compared with the log-rank test. Quality of life was evaluated using the QLQ-C30-STO22 questionnaires at the last follow-up contact. Results: The median PTV mean dose was 41.6 Gy. Only 0.73% of the PTV received <95% of the prescribed dose, indicating excellent target coverage. The median kidney V20 and liver V30 were 14.1% and 16.1%, respectively. The 5-year overall survival (OS), progression-free survival, and locoregional control rates for all patients were 80.4%, 75.0%, and 93.2%, respectively. Stage, lactate dehydrogenase level, and immunophenotype were significant prognostic factors for OS, and only stage was a significant factor for locoregional control. Consolidation IMRT in patients with complete response after chemotherapy resulted in significantly better OS and progression-free survival than salvage IMRT in patients with non-complete response. Two of 8 patients who had chronic liver disease experienced grade 4 or grade 5 acute hepatic failure after 4 to 5 cycles of rituximab-based chemotherapy and IMRT (40 Gy). No other serious acute or late toxicity was observed. The long-term global and functional QOL scales were excellent, with negligible symptom scales. Conclusions: Intensity modulated radiation therapy yielded excellent target coverage and critical tissue sparing and achieved favorable outcomes with acceptable toxicity and good long-term QOL in early-stage PG-DLBCL.

    The authors report a case of a non-Hodgkin lymphoma of the small bowel, presenting with ulcerative lesions on radiological studies. primary intestinal lymphoma is considered a rare entity and its diagnosis criteria are quiet strict. The secondary form of the disease - involvement of the small bowel by systemic lymphoma - constitutes an infrequent clinical presentation of these neoplasms and must be considered when the criteria for primary disease are not fulfilled. Diagnosis is based on small bowel series studies and/or computed tomography findings, but the definitive diagnosis is established by biopsy. (author)

    2014-01-01

    Full Text Available Background. Lymphoma of the urinary bladder (LUB is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18(q21: 21. Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions. LUB is diagnosed by its characteristic morphology and immunohistochemical characteristics. Radiotherapy is a useful treatment.

    The objective of this study was to evaluate the cost effectiveness of no prophylaxis, primary prophylaxis (PP), or secondary prophylaxis (SP) with granulocyte colony-stimulating factors (G-CSFs), i.e., pegfilgrastim, lipegfilgrastim, filgrastim (6- and 11-day), or lenograstim (6- and 11-day), to reduce the incidence of febrile neutropenia (FN) in patients with stage II breast cancer receiving TC (docetaxel, cyclophosphamide) and in patients with non-Hodgkin lymphoma (NHL) receiving R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) over a lifetime horizon from a Belgian payer perspective. A Markov cycle tree tracked FN events during chemotherapy (3-week cycles) and long-term survival (1-year cycles). Model inputs, including the efficacy of each strategy, risk of reduced relative dose intensity (RDI), and the impact of RDI on mortality, utilities, and costs (in €; 2014 values) were estimated from public sources and the published literature. Incremental cost-effectiveness ratios (ICERs) were assessed for each strategy for costs per FN event avoided, life-year (LY) saved, and quality-adjusted LY (QALY) saved. LYs and QALYs saved were discounted at 1.5% annually. Deterministic and probabilistic sensitivity analyses (DSAs and PSAs) were conducted. Base-case ICERs for PP with pegfilgrastim relative to SP with pegfilgrastim were €15,500 per QALY and €14,800 per LY saved for stage II breast cancer and €7800 per QALY and €6900 per LY saved for NHL; other comparators were either more expensive and less effective than PP or SP with pegfilgrastim or had lower costs but higher ICERs (relative to SP with pegfilgrastim) than PP with pegfilgrastim. Results of the DSA for breast cancer and NHL comparing PP and SP with pegfilgrastim indicate that the model results were most sensitive to the cycle 1 risk of FN, the proportion of FN events requiring hospitalization, the relative risk of FN in cycles ≥2 versus cycle 1, no history of FN, and the

    Full Text Available Victoria Mary Lendrum CohenSt. Bartholomew’s and Moorfields Eye Hospital, London UKAbstract: Most lymphomas that involve the ocular adnexal structure are low grade, B cell, non-Hodgkin’s lymphomas. The treatment depends upon the grade and stage of the disease. High grade lymhoma requires treatment with systemic chemotherapy whereas the localized low grade (extranodal marginal zone lymphoma can be successfully managed with local radiotherapy. Chlamydia psittaci infection is associated with low grade ocular lymphoma; however there is wide geographic variation in the strength of this association. Blanket antibiotic therapy is not advised unless there is proof of an infective agent. The monoclonal antibody, rituximab, may be successful for CD20 positive lymphoma, although it is likely that rituximab will have better long-term results when used in combination with systemic chemotherapy.Keywords: ocular adnexal lymphoma, mucosa associated lymphoid tissue, extranodal marginal zone lymphoma, Chlamydia psittaci, rituximab, radiotherapy, chemotherapy

    Primary lymphomas of bone or skeletal muscle are rare entities. The most frequent among these diseases are primary non-Hodgkin's lymphomas of bone. They account for 3-5% of all bone tumors and 5% of all primary extranodal non-Hodgkin's lymphomas. Primary manifestations of Hodgkin's disease in bone or skeletal muscle are rarities. Primary non-Hodgkin's lymphomas of skeletal muscle are rarities as well.Primary non-Hodgkin's lymphomas of bone can be found in any patient age. A preference exists for the 3.-6. decade of life. The radiographic appearance of these entities resembles other aggressive bone tumors.Their differential diagnosis includes - depending on the patient's age - Ewing's sarcoma,malignant fibrous histiocytoma,metastases of small cell tumors and osteomyelitis.Further differential diagnoses are the peripheral primitiv neuroektodermal tumor (PNET), osteosarcoma, eosinophilic granuloma and fibrosarcoma.Treatment of primary non-Hodgkin's lymphomas uses combinations of chemotherapy and radiation therapy.Operative treatment is reserved for the treatment of complications.The prognosis of primary non-Hodgkin's lymphomas is reflected by 10-year-survival-rates without recurrence of more than 80% in unifocal manifestations.

    Purpose: The purpose of this study was to evaluate the risks of second cancers and cardiovascular diseases associated with an optimized volumetric modulated arc therapy (VMAT) planning solution in a selected cohort of stage I/II Hodgkin lymphoma (HL) patients treated with either involved-node or involved-site radiation therapy in comparison with 3-dimensional conformal radiation therapy (3D-CRT). Methods and Materials: Thirty-eight patients (13 males and 25 females) were included. Disease extent was mediastinum alone (n=8, 21.1%); mediastinum plus unilateral neck (n=19, 50%); mediastinum plus bilateral neck (n=11, 29.9%). Prescription dose was 30 Gy in 2-Gy fractions. Only 5 patients had mediastinal bulky disease at diagnosis (13.1%). Anteroposterior 3D-CRT was compared with a multiarc optimized VMAT solution. Lung, breast, and thyroid cancer risks were estimated by calculating a lifetime attributable risk (LAR), with a LAR ratio (LAR VMAT -to-LAR 3D-CRT ) as a comparative measure. Cardiac toxicity risks were estimated by calculating absolute excess risk (AER). Results: The LAR ratio favored 3D-CRT for lung cancer induction risk in mediastinal alone (P=.004) and mediastinal plus unilateral neck (P=.02) presentations. LAR ratio for breast cancer was lower for VMAT in mediastinal plus bilateral neck presentations (P=.02), without differences for other sites. For thyroid cancer, no significant differences were observed, regardless of anatomical presentation. A significantly lower AER of cardiac (P=.038) and valvular diseases (P<.0001) was observed for VMAT regardless of disease extent. Conclusions: In a cohort of patients with favorable characteristics in terms of disease extent at diagnosis (large prevalence of nonbulky presentations without axillary involvement), optimized VMAT reduced heart disease risk with comparable risks of thyroid and breast cancer, with an increase in lung cancer induction probability. The results are however strongly influenced by the

    Background and purpose: radiotherapy of Hodgkin's lymphoma has evolved from extended-field to involved-field (IF) radiotherapy reducing toxicity whilst maintaining high cure rates. Recent publications recommend further reduction in the radiation field to involved-node (IN) radiotherapy; however, this concept has never been tested in a randomized trial. The German Hodgkin Study Group aims to compare it with standard IF radiotherapy in their future HD17 trial. Patients and methods: all patients must be examined by the radiation oncologist before the start of chemotherapy. At that time, patients must have complete staging CT scans. For patients with IN radiotherapy, a radiation planning CT before and after chemotherapy with patients in the treatment position is recommended. Fusion techniques, allowing the overlapping of the pre- and postchemotherapy CT scans, should be used. Usage of PET-CT scans with patients in the treatment position is recommended, whenever possible. Results: the clinical target volume encompasses the initial volume of the lymph node(s) before chemotherapy and incorporates the initial location and extent of the disease taking the displacement of the normal tissues into account. The margin of the planning target volume should be 2 cm in axial and 3 cm in craniocaudal direction. If necessary, it can be reduced to 1-1.5 cm. To minimize lung and cardiac toxicity, the target definition in the mediastinum is different. Conclusion: the concept of IN radiotherapy has been proposed as a means to further improve the therapeutic ratio by reducing the risk of radiation-induced toxicity, including second malignancies. Field sizes will further decrease compared to IF radiotherapy. (orig.)

    Full Text Available A 64-year old woman with a long standing Sjogren’s syndrome was undergoing evaluation for renal transplant surgery when two pulmonary opacities were detected on chest CT. Subsequent biopsy revealed extranodal marginal B-cell non-Hodgkin’s lymphoma (NHL. An FDG-PET/CT scan was then performed which demonstrated isolated FDG avid pulmonary involvement. After therapy, FDG-PET/CT scans showed good response to treatment with near complete resolution of FDG avidity. This rare case illustrates the rare pulmonary manifestation of extranodal lymphoma in a patient with Sjogren’s syndrome and emphasizes the value of FDG PET/CT in the initial staging and evaluation of response to treatment, which has not previously been published.

    In B-non-Hodgkin lymphomas, Lyn and Cbp/PAG constitute the core of an oncogenic signalosome that captures the Phosphatidylinositol-3-kinase, the Spleen tyrosine kinase and the Signal transducer and activator of transcription-3 to generate pro-survival and proliferative signals. Lymphoma lines corresponding to follicular, mantle-cell and Burkitt-derived lymphomas display type-specific signalosome organizations that differentially activate PI3K, Syk and STAT3. In the follicular lymphoma line, PI3K, Syk and STAT3 were optimally activated upon association with the Lyn-Cbp/PAG signalosome, while in the Burkitt lymphoma-derived line, the association with Cbp/PAG and activation of PI3K were interfered with by the latent membrane proteins encoded by the Epstein-Barr virus. In the Jeko-1 mantle-cell line, a weak association of Syk with the Lyn-Cbp/PAG signalosome resulted in poor activation of Syk, but in those cells, as in the follicular and Burkitt-derived lines, efficient apoptosis induction by the Syk inhibitor R406 indicated that Syk is nonetheless an important prosurvival element and therefore a valuable therapeutic target. In all configurations described herein is the Lyn-Cbp/PAG signalosome independent of external signals and provides efficient means of activation for its associated lipid and protein kinases. In follicular and Burkitt-derived lines, Syk appears to be activated following binding to Cbp/PAG and no longer requires B-cell receptor-associated activation motifs for activation. Assessment of the different modalities of Lyn-Cbp/PAG signalosome organization could help in selecting the appropriate combination of kinase inhibitors to eliminate a particular type of lymphoma cells.

    Mainly because of the diversity of clinical presentations, diagnostic delays in lymphoma can be excessive. The time spent in primary care before referral to the specialist may be relatively short compared with the interval between hospital appointment and diagnosis. Although studies have examined the diagnostic intervals and referral patterns of patients with lymphoma, the time to diagnosis of outpatient compared to inpatient settings and the costs incurred are unknown. We performed a retrospective study at two academic hospitals to evaluate the time to diagnosis and associated costs of hospital-based outpatient diagnostic clinics or conventional hospitalization in four representative lymphoma subtypes. The frequency, clinical and prognostic features of each lymphoma subtype and the activities of the two settings were analyzed. The costs incurred during the evaluation were compared by microcosting analysis. A total of 1779 patients diagnosed between 2006 and 2016 with classical Hodgkin, large B-cell, follicular, and mature nodal peripheral T-cell lymphomas were identified. Clinically aggressive subtypes including large B-cell and peripheral T-cell lymphomas were more commonly diagnosed in inpatients than in outpatients (39.1 vs 31.2% and 18.9 vs 13.5%, respectively). For each lymphoma subtype, inpatients were older and more likely than outpatients to have systemic symptoms, worse performance status, more advanced Ann Arbor stages, and high-risk prognostic scores. The admission time for diagnosis (i.e. from admission to excisional biopsy) of inpatients was significantly shorter than the time to diagnosis of outpatients (12.3 [3.3] vs 16.2 [2.7] days; P cost of €4039.56 (513.02) per inpatient and of €1408.48 (197.32) per outpatient, or a difference of €2631.08 per patient. Although diagnosis of lymphoma was quicker with hospitalization, the outpatient approach seems to be cost-effective and not detrimental. Despite the considerable savings with the latter

    Hodgkin’s lymphoma most commonly presents with progressive painless enlargement of peripheral lymph nodes, especially around the cervical region. At the time of diagnosis osseous involvement is uncommon and even in the late stages only 9–35% of cases have any bony involvement. Rarely Hodgkin’s lymphoma presents as an osseous lesion without involvement of lymph nodes, therefore the histological diagnosis of osseous Hodgkin’s lymphoma can be problematic. Here, the authors present a rare case of...

    The article is based on the treatment results of 44 patients with follicular tunor of thyroid gland. A staged morphological assessment of thyroid nodes was performed for all patients: in case of preoperative fine-needle biopsy, urgent intraoperative study and according to results of final histological research. The urgent histological study of surgical material was conducted for 44 patients with diagnosis "follicular tumor" according to fine-needle biopsy. The data of final histological study were matched with findings of intraoperative research. A micro-follicular adenoma was detected in 22 patients (50%) and 6 (13,6%) patients had this diagnosis combined with autoimmune thyroiditis. The general part of patients didn't changed in final study, but the rate of diagnosis "micro-follicular adenoma against the background of autoimmune thyroiditis" increased. Papillary carcinoma was revealed in 5 (11,4%) patients and follicular cancer had 4 (9,1%) patients detected in intraoperative study and 3 (6,8%) more patients according to data of final research. The histopathologic feature of colloid goiter was observed in 7 (15,9%) cases and a part of such patients reduced to 6,8% during final study. One of the patients (2,3%) had final diagnosis "oncocytoma". In case of thyroid nodules detection the needle biopsy should be carried out regardless to the size of nodule. The authors recommended performing the surgery with the urgent histological study in case of undetermined histological report. The following surgical strategy was specified by the results of the urgent histological report.

    Full Text Available Vitiligo is a common autoimmune inflammatory disease where there is damage to the basal melanocytes of the epidermis. Hair follicles are the main reservoir of the melanocytes, and melanocytes stem cells, and these cells will supply the melanocytes for the basal layer of the epidermis when these cells are lost. But when these follicular melanocytes are damaged, this will cause follicular vitiligo either in a form gray/white hair or in form of follicular leukoderma. Although follicular vitiligo is not uncommon variant of vitiligo but rarely discussed and classified.

    Primary intramedullary spinal cord lymphoma (PISCL) is a rare diagnosis with poorly understood disease progression. Clarification of the factors associated with survival in PISCL patients is warranted. We conducted a population-based cohort study utilizing prospectively collected data from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with histological diagnosis of primary lymphoma in spinal cord (C72.0) from 1973 to 2012 in the SEER database were included. Multivariable survival analysis between patient, lesion characteristics, and PISCL-related death was performed to adjust for confounding factors. We included 346 PISCL patients in our study. Average age was 56.5 ± 17.8 years, with 62.7% being male. Racial distribution of these patients was white (87.6%), black (8.0%), and other (4.3%). More than half (55.8%) of patients were married. The most prevalent histology of PISCL was diffuse B-cell (46.2%), and the majority (55.2%) were low stage (Ann Arbor stage I/II). Most patients (67.9%) received radiation therapy. Average survival interval of patients with PISCL-related death (n=135, 39.0%) was 27.8 months. General cumulative survival probability at 1 year, 2 years, and 5 years was 73.8%, 67.9%, and 63.1%, respectively. Multivariable accelerated failure time (AFT) regression showed follicular lymphoma (HR:0.25, P=.008) and more recent diagnosis (HR:0.96, P<.001) was positively associated with PISCL-related survival. Conversely, nonwhite race (HR:1.69, P=.046), older age (HR:1.02, P<.001), unmarried status (HR:2.14, P<.001), and higher stage (HR:1.54, P=.022) were negatively associated with survival. Age, race, marital status, tumor histology, tumor stage, and year of diagnosis were associated with survival of PISCL. While most PISCL-related deaths occur within a 1-year period, subsequent slow progression was observed after the first year of survival. © The Author(s) 2016.

    Full Text Available Nine-hundred-eighty-nine patients with lymphoma were studied. Fifty-three cases (5.3% had lymphomatous craniocerebral infiltration. The principal factors of risk for this complication were: advanced stage of the lymphoma (III or IV, diffuse histiocytic, diffuse poorly differentiated lymphocytic, or mixed cellularity lymphoma histological type, bone marrow involvement, and previous systemic chemotherapy. Thirty-two per cent of the cases of meningeal lymphomatous infiltration were asymptomatic and represented autopsy findings. CT-scan was an useful test to detect brain focal parenchymatous infiltration, as opposed to meningeal infiltration. Mean survival time in patients with lymphomatous meningeal infiltration was 4.3 months, following the combined use of systemic chemotherapy, radiation therapy and intrathecal methotrexate. Two cases had primary cerebral lymphoma, although without associated immunodeficiency Twenty patients (2% had intracranial hemorrhage, in clear relationship with platelet alterations. Fifteen patients (1.5% had CNS infection, caused by common bacteriae or opportunistic agents. In 7 cases, the diagnosis was made at autopsy. Thirty-six autopsies were performed. In 8 cases (22%, pathologic findings such as, demyelination, microcalcificat ons, coagulative necrosis, or gliosis, suggested complications from treatment.

    Purpose: To compare the dose reduction to organs at risk (OARs) with proton therapy (PT) versus three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) in patients with mediastinal Hodgkin lymphoma (HL) enrolled on a Phase II study of involved-node radiotherapy (INRT). Methods and Materials: Between June 2009 and October 2010, 10 patients were enrolled on a University of Florida institutional review board-approved protocol for de novo 'classical' Stage IA-IIIB HL with mediastinal (bulky or nonbulky) involvement after chemotherapy. INRT was planned per European Organization for Research and Treatment of Cancer guidelines. Three separate optimized plans were developed for each patient: 3D-CRT, IMRT, and PT. The primary end point was a 50% reduction in the body V4 with PT compared with 3D-CRT or IMRT. Results: The median relative reduction with PT in the primary end point, body V4, was 51% compared with 3D-CRT (p = 0.0098) and 59% compared with IMRT (p = 0.0020), thus all patients were offered treatment with PT. PT provided the lowest mean dose to the heart, lungs, and breasts for all 10 patients compared with either 3D-CRT or IMRT. The median difference in the OAR mean dose reduction with PT compared with 3D-CRT were 10.4 Gy/CGE for heart; 5.5 Gy/CGE for lung; 0.9 Gy/CGE for breast; 8.3 Gy/CGE for esophagus; and 4.1 Gy/CGE for thyroid. The median differences for mean OAR dose reduction for PT compared with IMRT were 4.3 Gy/CGE for heart, 3.1 Gy/CGE for lung, 1.4 Gy/CGE for breast, 2.8 Gy/CGE for esophagus, and 2.7 Gy/CGE for thyroid. Conclusions: All 10 patients benefitted from dose reductions to OARs with PT compared with either 3D-CRT or IMRT. It is anticipated that these reductions in dose to OAR will translate into lower rates of late complications, but long-term follow-up on this Phase II INRT study is needed.

    A 67 year old woman with a 10 year history of rheumatoid arthritis (RA) treated with methotrexate and prednisone, presented with a 2 year history of worsening multiple cutaneous plaques of variable appearance. Two distinct skin lesions were biopsied to reveal a composite cutaneous lymphoma, possibly caused by long term methotrexate therapy. An [18F] fluoro-2-deoxy-D-glucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) was performed to stage the malignancy, and was later repeated to evaluate response to chemotherapy, which guided subsequent management. We present the PET/CT imaging findings of this very rare iatrogenic (methotrexate induced) immunodeficiency-associated lymphoproliferative disorder

    This chapter deals with the radiotherapy and cytotoxic chemotherapy of the malignant lymphomas. Included within this group are Hodgkin's disease, non-Hodgkin's lymphoma, mycosis fungoides, and chronic lymphatic leukaemia. A further section deals with the myeloproliferative disorders, including granulocytic leukaemia, polycythaemia vera, and primary thrombocythaemia. Excluded are myeloma and reticulum cell sarcoma of bone and acute leukaemia. With regard to Hodgkin's disease, the past 25 years have seen general recognition of the curative potential of radiotherapy, at least in the local stages, and, more recently, awareness of the ability to achieve long-term survival after combination chemotherapy in generalised or in recurrent disease. At the same time the importance of staging has become appreciated and the introduction of procedures such as lymphography, staging laparotomy, and computer tomography (CT) has enormously increased its reliability. Advances have not been so dramatic in the complex group of non-Hodgkins's lymphomas, but are still very real

    Most of Hodgkin lymphoma patients survive due to combined chemo/radiotherapy. Improved survival brings long-term side effects to the front, which may determine the patients' subsequent quality of life and expected lifetime. This manuscript aims to analyze lung manifestations of Hodgkin lymphoma and treatment related pulmonary complications, demonstrated with own cases. The lung involvement in Hodgkin lymphoma is often secondary, and primary pulmonary involvement is very rare. The authors found 8-12% of lung involvement among their patients. Side effects of treatment consist of pulmonary infections in conjuction with immunosuppression, while on the other hand bleomycin and chest irradiation as part of current standard of care induced pneumonitis and fibrosis are reported. The pulmonary involvement in Hodgkin lymphoma may cause differential diagnostic difficulty. Lung involvement could modify stage and consequently treatment, and the development of side effects might determine later quality of life and expected lifetime. Therefore, identification of lung involvement is crucial.

    Tumor necrosis factor-α-inducible protein-2 (TNFAIP2) is a protein upregulated in cultured cells treated with tumor necrosis factor α (TNF), but its expression in normal and neoplastic tissues remains largely unknown. Here, we use standard immunohistochemical techniques to demonstrate that TNFAIP2 is normally expressed by follicular dendritic cells, interdigitating dendritic cells, and macrophages but not by lymphoid cells in secondary lymphoid tissues. Consistent with this expression pattern, we found strong TNFAIP2 staining of tumor cells in 4 of 4 cases (100%) of follicular dendritic cell sarcoma and in 3 of 3 cases (100%) of histiocytic sarcoma. Although TNFAIP2 is not expressed by the small and intermediate-sized neoplastic B cells comprising follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma, or marginal zone lymphoma, we observed strong TNFAIP2 staining of the large, neoplastic cells in 31 of 31 cases (100%) of classical Hodgkin lymphoma, in 12 of 12 cases (100%) of nodular lymphocyte-predominant Hodgkin lymphoma, and in 27 of 31 cases (87%) of primary mediastinal (thymic) large B-cell lymphoma. In contrast, TNFAIP2 was expressed by malignant cells in only 2 of 45 cases (4%) of diffuse large B-cell lymphoma, not otherwise specified, in 2 of 18 cases (11%) of Burkitt lymphoma, and in 1 of 19 cases (5%) of anaplastic large cell lymphoma. Further analysis indicates that TNFAIP2, as a single diagnostic marker, is more sensitive (sensitivity=87%) and specific (specificity=96%) than TRAF1, nuclear cRel, or CD23 for distinguishing the malignant B cells of primary mediastinal (thymic) large B-cell lymphoma from those of its morphologic and immunophenotypic mimic, diffuse large B-cell lymphoma, not otherwise specified. Thus, TNFAIP2 may serve as a useful new marker of dendritic and histiocytic sarcomas, the aberrant expression of which in the malignant cells of classical Hodgkin lymphoma and primary mediastinal (thymic) large B-cell lymphoma

    Background: a chylothorax is a rare complication of mostly advanced malignant lymphomas. A case of a refractory chylothorax unresponsive to chemotherapy and successfully treated with radiotherapy is reported. Case report: a 45-year-old woman with recurrent stage IV low-grade follicular non-Hodgkin's lymphoma and a progressive chylothorax is described. The CT scans showed bulky lymphadenopathy at the thoracic trunk but no detectable enlargement of mediastinal lymph nodes. After ineffective pretreatment including chemotherapy and chest drainage, fractionated radiotherapy to the celiac trunk (20.4 Gy) and the thoracic duct (15 Gy) was performed. Result: already after 7.5 Gy a rapid decline of chylothorax was noted and the chest drain could be removed. A complete remission of the chylothorax could be achieved after 20.4 Gy. During a follow-up of 16 months no recurrence of chylothorax occurred. CT scans showed nearly complete remission of the lymphadenopathy of the celiac trunk 12 months after radiotherapy. Conclusion: radiotherapy with limited total doses is an effective treatment option for lymphoma-associated chylothorax and should always be taken into consideration, especially in cases unresponsive to chemotherapy.

    Previous studies in other provinces of China (Beijing, Xinjiang, Shanxi, Jiangxi, Shanghai, Guangdong, and Taiwan) suggest that the distributions of lymphoma subtypes differ compared with Western populations. In order to evaluate the characteristics of malignant lymphoma in Sichuan, China, we analyzed case series data from incident lymphoma patients diagnosed in 2008 from three hospitals, including a total of 1629 cases and including only current residents of Sichuan. The median age of diagnosis for cases was 54 years, with a higher proportion of male cases compared with female cases. The most commonly diagnosed subtypes included diffuse large B-cell lymphoma (40.4%), NK/T-cell lymphoma (NKTCL; 11.8%), mixed cellularity Hodgkin lymphoma (7.0%), mantle cell lymphoma (4.8%), and marginal zone B-cell lymphoma (3.9%). Differences in demographic characteristics between Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) cases were apparent for median age at diagnosis (HL: 34 years; NHL: 57 years), and NHLs accounted for nearly all (99.3%) of the 931 cases of extranodal lymphoma. These findings indicate a higher proportion of NKTCL cases and a lower proportion of follicular lymphoma cases (2.3%) in these hospitals in Sichuan, relative to reports from some other provinces within China (e.g., Shanghai and Shanxi) and the USA.

    Lymphomas are a heterogeneous group of neoplasms with distinct morphologic, immunologic, and cytogenetic characteristics. Overlapping morphologic and immunophenotypic features often makes accurate diagnosis difficult. Cytogenetics helps simplify the diagnostic complexities presented in transforming and progressive lymphoid malignancies. Genetic studies using technical advances such as fluorescence in situ hybridization and the newer approaches of array comparative genomic hybridization and gene expression profiling play a critical and often defining role in the diagnosis, progression, prognosis, and therapeutic stratification. This article reviews characteristic cytogenetic abnormalities in specific subtypes of lymphomas at diagnosis, disease progression, and prognosis.

    To describe the clinicopathological features, treatment, treatment outcome and sequelae of patients with nodular lymphocyte, predominant Hodgkin's lymphoma (NLPHL) in Saudi population. This is a retrospective review of 29 patients with lymphocyte predominant Hodgkin's lymphoma treated at two major hospitals (King Khalid University Hospital and Security Forces Hospital) in Riyadh, Kingdom of Saudi Arabia from 1985 to 2000. Histological subtypes were confirmed by review of hematoxylin and eosin paraffin sections and immunochemistry. Details of clinical presentation, stage, treatment and results of treatment were analyzed. On pathological reappraisal of the 29 cases, 3 patients had nodular sclerosis Hodgkin's lymphoma and 4 patients were reclassified as lymphocyte rich classical Hodgkin's lymphoma. Twenty-two patients were identified to have nodular lymphocyte predominant Hodgkin's lymphoma (NLPHL). These patients comprised of 18 mails and 4 female patients with a median age at presentation of 25 years. Nineteen (86%) patients had an early stage (Ann Arbor stage I and II) disease, 2 had stage III and one patient had stage IV. The majority of patients presented with peripheral lymphadenopathy and long duration of symptoms. For 16 patients, details of treatment and follow-up were available. All of these achieved a complete response to initial treatment. Four patients relapsed following the primary therapy. Our results are consistent with the previous series reported from Western countries and confirmed that the patients with NLPHL have characteristic clinical and pathological profile that distinguish it from other types of Hodgkin's lymphoma. The disease tends to run an unusual course and although most patients achieve an excellent response to therapy there is a tendency to replace. treatment remains controversial; however, recent understanding of the molecular pathogenesis of NLPHL could lead to modification of current therapeutic approach to this disease.

  8. Monitoring and controlling follicular activity in camelids.

    Tibary, Ahmed

    2018-03-15

    This paper reviews that state of our knowledge concerning follicular wave dynamics, monitoring and manipulation. All camelids have overlapping follicular waves in absence of ovulation which is induced by a seminal plasma factor (βNGF). The interval between follicular waves varies. The size of the ovulatory follicle varies between 11 and 25 mm in camels and between in 6 and 13 mm in South American Camelids. The interval between induction of ovulation and next ovulatory follicle is 15 ± 1 day for all camelids. Follicular activity is best monitored by transrectal ultrasonography. Progesterone therapy for 7-15 days seems to suppress follicular dominance but does not completely inhibit follicular recruitment. Combination of estradiol and progesterone seems to provide better control of follicular activity. Both methods have provided variable results in the synchronization of follicular waves. Combination of induction of ovulation with GnRH and luteolysis at predetermined times shows some promise in synchronization of follicular dominance. These synchronization protocols require further investigation in order to provide practical approaches for fixed-time breeding. Ovarian superstimulation with FSH and eCG alone or in combination is somewhat successful. The best results are obtained when treatment is initiated at the emergence of a new follicular wave after induction of ovulation or following treatment with progesterone for 7-14 days. However, response remains extremely variable particularly in terms of ovulation rate and number of recovered embryos. Sources of this variability need to be studied including the effects of season, nutrition, doses and frequency of administration of gonadotropin. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Lymphomas are a heterogeneous group of diseases that arise from the constituent cells of the immune system or from their precursors. 18F-fludeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT is now the cornerstone of staging procedures in the state-of-the-art management of Hodgkin′s disease and aggressive non-Hodgkin′s lymphoma. It plays an important role in staging, restaging, prognostication, planning appropriate treatment strategies, monitoring therapy, and detecting recurrence. However, its role in indolent lymphomas is still unclear and calls for further investigational trials. The protean PET/CT manifestations of lymphoma necessitate a familiarity with the spectrum of imaging findings to enable accurate diagnosis. A meticulous evaluation of PET/CT findings, an understanding of its role in the management of lymphomas, and knowledge of its limitations are mandatory for the optimal utilization of this technique.

    With approximately 10000 cases per year in France, non-Hodgkin's lymphoma (NHL) represents the most frequent hematological malignancy, and 5 to 10 % of new cases of cancers. NHLs constitute a heterogeneous group of lympho-proliferative diseases, including entities with very different epidemiological and evolutive characteristics, as well as prognosis and treatments. Several classifications exist, but in practice, we individualize aggressive NHL including Diffuse Large B-Cell Lymphomas (DLBCL) which is the most common lymphoma, and indolent NHL including follicular lymphomas and mucosa-associated lymphoid tissue (MALT) lymphomas. The role of the radiotherapy in the management of NHLs varies according to the specific sub-type of lymphoma, but it has become increasingly limited over time. Overall it finds indications with curative intent only in situations of localized LMNH: either associated with chemotherapy as part of a combined modality therapy as for the treatment of localized DLBCL, or as exclusive treatment specially in the rare situations of localized follicular lymphomas. Moreover, lymphocytes being extremely radiosensitive cells, radiotherapy retains excellent indications with palliative intent for the management of symptomatic bulky tumor masses, and that whatever the sub-type of NHLs may be. It is important to remember that even today the 'Involved Field' irradiation type remains the gold standard for the treatment of nodal NHLs, even if we witness at present the emergence of new types of irradiation, which aim to reduce the amount of irradiated tissues to try to limit the risks of delayed radio-induced complications. The purpose of this article is to clarify the specific aspects (epidemiological, radio-anatomical and prognostic characteristics) of each NHLs'sub-types (except primary central nervous system lymphomas), as well as the practical modalities of the irradiation (illustrated by a clinical case record) when an indication of

    Purpose Advanced-stage mycosis fungoides (MF; stage IIB to IV) and Sézary syndrome (SS) are aggressive lymphomas with a median survival of 1 to 5 years. Clinical management is stage based; however, there is wide range of outcome within stages. Published prognostic studies in MF/SS have been single-center trials. Because of the rarity of MF/SS, only a large collaboration would power a study to identify independent prognostic markers. Patients and Methods Literature review identified the following 10 candidate markers: stage, age, sex, cutaneous histologic features of folliculotropism, CD30 positivity, proliferation index, large-cell transformation, WBC/lymphocyte count, serum lactate dehydrogenase, and identical T-cell clone in blood and skin. Data were collected at specialist centers on patients diagnosed with advanced-stage MF/SS from 2007. Each parameter recorded at diagnosis was tested against overall survival (OS). Results Staging data on 1,275 patients with advanced MF/SS from 29 international sites were included for survival analysis. The median OS was 63 months, with 2- and 5-year survival rates of 77% and 52%, respectively. The median OS for patients with stage IIB disease was 68 months, but patients diagnosed with stage III disease had slightly improved survival compared with patients with stage IIB, although patients diagnosed with stage IV disease had significantly worse survival (48 months for stage IVA and 33 months for stage IVB). Of the 10 variables tested, four (stage IV, age > 60 years, large-cell transformation, and increased lactate dehydrogenase) were independent prognostic markers for a worse survival. Combining these four factors in a prognostic index model identified the following three risk groups across stages with significantly different 5-year survival rates: low risk (68%), intermediate risk (44%), and high risk (28%). Conclusion To our knowledge, this study includes the largest cohort of patients with advanced-stage MF/SS and

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors. Copyright © 2015 AEC.

    Objective: To investigate the prognostic factors and treatment outcome of primary non-Hodgkin's thyroid lymphoma. Methods: From January 1985 to February 2003, 31 patients pathologically confirmed as suffering from B cell non-Hodgkin's lymphoma and treated in our hospital, were retrospectively analyzed. Pathology: extra-nodal marginal B cell lymphoma (mucosa-associated lymphoma, MALT) 11, diffuse large cell B cell lymphoma 10, diffused mixed cell type 3, B cell lymphoblastoma 1, follicular lymphoma 1, and unclassifiable 5. According to Ann Arbor staging system, there were 9 stage I, 22 stage II lesions, the tumor in 8 patients was confined to the thyroid, 18 showed extrathyroid extension and 5 patients were excluded due to lack of complete data. Twelve patients had upper-mediastinal involvement simultaneously. According to the international prognostic index (IPI), 16 patients had no or one risk factor (low-risk group), while 9 patients had two or three risk factors (moderate risk group), 6 cases were excluded because of lacking complete data. Seven patients were biopsied only and 24 patients received operation: unilateral lobectomy 10, sub-total thyroidectomy 10 and total thyroidectomy 4. Twenty-five patients were supplemented with chemotherapy and/or radiotherapy: 7 as the former, 8 as the latter and 10 as both. Radiotherapy- linear accelerator 6MV X-ray irradiation was given: D T 40-63 Gy(median 50 Gy) to the primary site, the whole cervical areas D T 40-55 Gy(median 50 Gy), the mediastinum D T 30-50 Gy(median 45 Gy), radiotherapy had to be seceded in two patients due to extra-portal progression of tumor. Chemotherapy was given to 17 patients as multidrug regimen with CHOP for 9 patients, BACOP for 5 and MOPP, CHEP, CBE, each for one patient. Results: The overall 5-year survival rate (OS), cancer specific survival rate(CSS) and disease- free survival rate (DFS) for all patients were 64%, 67% and 55%. The 5-year OS and CSS of stage I and stage II patients were 83

    Follicular bronchiolitis is a lymphoproliferative form of interstitial lung disease (ILD) defined by the presence of peribronchial lymphoid follicles. Follicular bronchiolitis has been associated with viral infection, autoimmune disease and immunodeficiency. The most common clinical manifestation is respiratory distress in infancy followed by a prolonged course with gradual improvement. We found no reports of systematic review of high-resolution computed tomography (HRCT) findings in pediatric follicular bronchiolitis. The purpose of this study was to describe the HRCT findings of follicular bronchiolitis in children and correlate these imaging findings with histopathology. A 5-year retrospective review of all pathology-proven cases of follicular bronchiolitis was performed. Inclusion criteria were age <18 years and an HRCT within 6 months of lung biopsy. HRCTs were reviewed by three observers and scored using the system previously described by Brody et al. Six patients met the inclusion criteria with age range at HRCT of 7-82 months (median: 39.5 months). Pulmonary nodules (n=6) were the most common HRCT finding followed by focal consolidation (n=5), bronchiectasis (n=4) and lymphadenopathy (n=3). Tree and bud opacities and nodules on CT correlated with interstitial lymphocytic infiltrates and discrete lymphoid follicles on pathology. The salient HRCT findings of childhood follicular bronchiolitis are bilateral, lower lung zone predominant pulmonary nodules and bronchiectasis with infantile onset of symptoms. These characteristic HRCT findings help differentiate follicular bronchiolitis from other forms of infantile onset ILD. (orig.)

    Polycystic ovary syndrome (PCOS), a major cause of anovulatory infertility, is characterized by arrested follicular growth. Altered protein levels in the follicular fluid surrounding the ovum may reflect the molecular defects of folliculogenesis in these women. To identify differentially regulated proteins in PCOS by comparing the follicular fluid protein repertoire of PCOS with healthy women. The follicular fluid samples were collected from PCOS and normo-ovulatory women undergoing in vitro fertilization. Follicular fluid proteins were subjected to digestion using trypsin, and resultant peptides were labeled with isobaric tags for relative and absolute quantification reagents and analyzed by liquid chromatography tandem mass spectrometry. Differential abundance of selected proteins was confirmed by ELISA. A total of 770 proteins were identified, of which 186 showed differential abundance between controls and women with PCOS. Proteins involved in various processes of follicular development including amphiregulin; heparan sulfate proteoglycan 2; tumor necrosis factor, α-induced protein 6; plasminogen; and lymphatic vessel endothelial hyaluronan receptor 1 were found to be deregulated in PCOS. We also identified a number of new proteins from follicular fluid, whose function in the ovary is not yet clearly established. These include suprabasin; S100 calcium binding protein A7; and helicase with zinc finger 2, transcriptional coactivator. Proteins indispensable for follicular growth were found to be differentially expressed in follicular fluid of women with PCOS, which may in part explain the aberrant folliculogenesis observed in these women.

    Plasmablastic lymphoma (PBL) is a rare and aggressive subtype of non-Hodgkin lymphoma that commonly occurs in human immunodeficiency virus (HIV)-positive individuals, and affects oral sites. Occasionally, it has been described in HIV-negative patients and involving non-oral sites. Pathologically, PBL is a high-grade B-cell lymphoma that displays the immunophenotype of a terminally differentiated B-lymphocyte with loss of B-cell markers (CD20) and expression of plasma-cell antigens. Epstein-Barr virus infection and MYC rearrangements are frequently observed. Treatment of PBL is challenging because of the lack of established treatment and poor outcomes, with median survival times shorter than one year. In this review, we discuss the clinical and epidemiologic spectrum of PBL as well as its distinct pathological features. Finally, we summarize the currently available approaches for the treatment of patients with PBL. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    Extranodal lymphoma are rare, in particular, breast non-Hodgkin's lymphoma has an impact of lower 0.5%. It is difficult to diagnose during the pre-operative period, since it can be confused with breast carcinoma. A 52 years old female patient was sent due to a lump in her left breast identified in a mammogram. A study was conducted with supplementary tests, being eventually diagnosed as low-grade B-cell follicular lymphoma. She was subjected to a mammary and axillary radioguided occult lesion localisation (ROLL). After, radiation therapy was delivered. It is a very rare pathology, therefore, there is not relevant research to show effective treatment or diagnosis.

    Full Text Available Epigenetic modifications and DNA methylation in particular, have been recognized as important mechanisms to alter gene expression in malignant cells. Here, we identified candidate genes which were upregulated after an epigenetic treatment of B-cell lymphoma cell lines (Burkitt's lymphoma, BL; Follicular lymphoma, FL; Diffuse large B-cell lymphoma, DLBCL activated B-cell like, ABC; and germinal center like, GCB and simultaneously expressed at low levels in samples from lymphoma patients. Qualitative methylation analysis of 24 candidate genes in cell lines revealed five methylated genes (BMP7, BMPER, CDH1, DUSP4 and LRP12, which were further subjected to quantitative methylation analysis in clinical samples from 59 lymphoma patients (BL, FL, DLBCL ABC and GCB; and primary mediastinal B-cell lymphoma, PMBL. The genes LRP12 and CDH1 showed the highest methylation frequencies (94% and 92%, respectively. BMPER (58%, DUSP4 (32% and BMP7 (22%, were also frequently methylated in patient samples. Importantly, all gene promoters were unmethylated in various control samples (CD19+ peripheral blood B cells, peripheral blood mononuclear cells and tonsils as well as in follicular hyperplasia samples, underscoring a high specificity. The combination of LRP12 and CDH1 methylation could successfully discriminate between the vast majority of the lymphoma and control samples, emphasized by receiver operating characteristic analysis with a c-statistic of 0.999. These two genes represent promising epigenetic markers which may be suitable for monitoring of B-cell lymphoma.

    It has been stated that the effectiveness of chemotherapy for the treatment of primary central nervous system lymphoma (PCNSL) has not been proved; however, the intravenous or intrathecal treatment with methotrexate dse has been used and satisfactory results have been obtained. The case of a patient with diagnosis of PCNSL and an intraparenchymatous infiltration on the left temporoparietal region at the onset of the disease, and later on the homo lateral pontocerebellar angle, is reported. Systemic and intrathecal onco specific polychemotherapy and holocranial radiotherapy were applied. All the reported lesions disappeared, and a satisfactory evolution was observed, although this patient had severe late alterations of his higher psychical functions with progressive cognoscitive and behavioral disorders. Lesions such as cortical atrophy, leukoatrophy, dilated ventricular system, and hyper intensive areas in the white matter of the brain without tumoral recurrence were evidenced in the imaging study. The positive impact of chemotherapy on the treatment of primary brain lymphoma was verified, as well as the neurotoxicity in the central nervous system caused by the onco specific treatment (radiotherapy and chemotherapy). It was considered that radiotherapy and combined therapy should be only used in relapses. It was recommended to conduct a comparative clinical study with periodical neuropsychological assessments to determine the possible neurotoxic effect caused by radiotherapy and chemotherapy. From the clinical and imaging point of view, the patient presented a neurotoxic atrophic leucoencephalopathy

    Abstract Non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) represent a heterogeneous group of malignant lymphoid tumors, which have distinct histological and/or biological characteristics with preferential nodal involvement. However, none of the previous studies have assessed the prevalence of common NHL and HL subtypes at each nodal site of involvement. The aim of our study was to determine the prevalence of HL and NHL subtypes depending on their nodal sites of involvement. We conducted a single-center retrospective study of 938 lymphoma cases diagnosed in the Pathology Department of Toulouse Purpan Hospital in France between 2001 and 2008, taking into account the site that corresponded to the diagnostic biopsy. The most frequent sites were cervical lymph nodes (36.8% of all cases), inguinal lymph nodes (16.4%), axillary lymph nodes (11.9%), and supraclavicular lymph nodes (11%). We found an unexpected association between intraparotid nodes and nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and between inguinal nodes and follicular lymphoma. The risk of having classical Hodgkin lymphoma (CHL) was 15 times greater in patients with mediastinal lymphoma compared to those with other sites of involvement. Regarding HL, nodal and extranodal mediastinal sites and supraclavicular nodes were more likely to be involved by nodular sclerosis Hodgkin lymphoma (NSCHL). In addition, intra-abdominal lymph nodes were more frequently involved by lymphocyte depleted Hodgkin lymphoma compared to inguinal nodes where NLPHL predominated. Our study shows that some lymph node sites have a disproportionate prevalence of specific subtypes of lymphoma. Identifying these sites may aid to diagnose and better elucidate the pathogenesis of these tumors. PMID:26107683

    A 67 year old woman with a 10 year history of rheumatoid arthritis (RA) treated with methotrexate and prednisone, presented with a 2 year history of worsening multiple cutaneous plaques of variable appearance. Two distinct skin lesions were biopsied to reveal a composite cutaneous lymphoma, possibly caused by long term methotrexate therapy. An [18F] fluoro-2-deoxy-D-glucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) was performed to stage the malignancy, and was later repeated to evaluate response to chemotherapy, which guided subsequent management. We present the PET/CT imaging findings of this very rare iatrogenic (methotrexate induced) immunodeficiency-associated lymphoproliferative disorder.

    Chemotherapy represents the most important therapeutic option in malignant lymphomas. Low to intermediate risk Hodgkin's disease is treated by a combination of chemotherapy and radiation. The new chemotherapy protocol BEACOPP has improved the outcome of advanced stages in comparison with the internationally accepted standard protocol COPP/ABVD. Dependent on the initial staging, cure rates between 50 and 95% can be achieved. Indolent non-Hodgkin's lymphomas usually present in advanced stages of disease. Chemotherapy in these cases has palliative character and aims at improving patients'quality of life and at avoiding complications due to the disease. In aggressive and very aggressive non-Hodgkin's lymphoma chemotherapy is curative and must be initiated immediately irrespective of the staging results. The efficacy of the standard protocol CHOP (cyclophosphamide,doxorubicin, vincristine and prednisone), that was established in the 1970s, has recently been improved by shortening of the therapy interval (CHOP-14 vs.CHOP-21),addition of etoposide (CHOEP) and combination with the monoclonal antibody rituximab (R-CHOP). The value of high dose chemotherapy with stem cell transplantation has been shown unequivocally only for aggressive non-Hodgkin lymphoma and relapsed Hodgkin's disease responsive to chemotherapy. The therapeutic strategy of malignant lymphomas is likely to be improved within the next years due to the introduction of novel cytostatic agents, the broadening application of monoclonal antibodies,upcoming new transplantation procedures and the development of substances with molecular targets.To rapidly increase our current knowledge on the topic it is mandatory to include patients into the large national and international multicenter studies.

    Here, we give an updated overview of the subtype distribution of lymphomas in East Asia and also present the genome sequencing data on two major subtypes of these tumors. The distribution of lymphoma types/subtypes among East Asian countries is very similar, with a lower proportion of B-cell malignancies and a higher proportion of T/natural killer (NK)-cell lymphomas as compared to Western populations. Extranodal NK/T-cell lymphoma is more frequently observed in East Asia, whereas follicular lymphoma and chronic lymphocytic leukemia, are proportionally lower. The incidence rate of lymphoma subtypes in Asians living in the US was generally intermediate to the general rate in US and Asia, suggesting that both genetic and environmental factors may underlie the geographical variations observed.Key cancer driver mutations have been identified in Asian patients with diffuse large B-cell lymphoma or extranodal NK/T-cell lymphoma through genome sequencing. A distinct somatic mutation profile has also been observed in Chinese diffuse large B-cell lymphoma patients. The incidence and distribution of lymphoma subtypes differed significantly between patients from East Asia and Western countries, suggesting subtype-specific etiologic mechanisms. Further studies on the mechanism underlying these geographical variations may give new insights into our understanding of lymphomagenesis.

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL can arise from lymphatic cells located in solid organs (extranodal and it accounts for 25 to 35% of all NHL. Primary lymphoma on the female genital tract (PLFGT is a rare disease, comprising 0.2 to 1.1% of all extranodal lymphomas in the female population. In this paper, the authors report an extremely rare case of a 48-year-old woman who exhibited an abnormal uterine bleeding, pelvic pain, and dysmenorrhea history. The transvaginal ultrasound showed an anteverted uterus measuring 153 cm3 in volume, with intramural leiomyomas. She underwent a total laparoscopic hysterectomy with bilateral salpingectomy. The histologic evaluation of the specimen showed a follicular lymphoma with diffuse pattern in the endometrium. This report illustrates the difficulty in the diagnosis of primary lymphomas of the female genital tract.

    Paraneoplastic syndromes are most often diagnosed in the setting of a known malignancy. It is not uncommon for a paraneoplastic disorder to develop before a cancer is identified. While syndrome of cerebellar degeneration has been identified as a paraneoplastic manifestation of Hodgkin's lymphoma, thymoma, lung and breast cancer, ovarian and testicular tumors, melanoma, renal cell carcinoma, follicular lymphoma and adenocarcinoma of stomach, its association with non-Hodgkin's lymphoma and particularly diffuse large B-cell lymphoma has not been established previously. This case report describes the primary presentation with signs of paraneoplastic cerebellar degeneration as the only manifestation of an underlying diffuse large B-cell lymphoma making it the first of its kind to be formally reported. Furthermore, it also includes the identification of associated paraneoplastic antibodies for this particular syndrome.

    We report a case of primary small-cell lymphocytic lacrimal gland lymphoma in a male diagnosed with primary antiphospholipid syndrome. These rare lymphomas are usually presented in the clinic as disseminations secondary to chronic lymphocytic leukaemia, and the primary site is rare in the orbit. Non-Hodgkin lymphomas are a heterogeneous group of tumours. Although treatment in the IE stage is usually radiotherapy, due to its association with antiphospholipid syndrome, systemic treatment with rituximab was administered.

    Pathology reports are rich in narrative statements that encode a complex web of relations among medical concepts. These relations are routinely used by doctors to reason on diagnoses, but often require hand-crafted rules or supervised learning to extract into prespecified forms for computational disease modeling. We aim to automatically capture relations from narrative text without supervision. We design a novel framework that translates sentences into graph representations, automatically mines sentence subgraphs, reduces redundancy in mined subgraphs, and automatically generates subgraph features for subsequent classification tasks. To ensure meaningful interpretations over the sentence graphs, we use the Unified Medical Language System Metathesaurus to map token subsequences to concepts, and in turn sentence graph nodes. We test our system with multiple lymphoma classification tasks that together mimic the differential diagnosis by a pathologist. To this end, we prevent our classifiers from looking at explicit mentions or synonyms of lymphomas in the text. We compare our system with three baseline classifiers using standard n-grams, full MetaMap concepts, and filtered MetaMap concepts. Our system achieves high F-measures on multiple binary classifications of lymphoma (Burkitt lymphoma, 0.8; diffuse large B-cell lymphoma, 0.909; follicular lymphoma, 0.84; Hodgkin lymphoma, 0.912). Significance tests show that our system outperforms all three baselines. Moreover, feature analysis identifies subgraph features that contribute to improved performance; these features agree with the state-of-the-art knowledge about lymphoma classification. We also highlight how these unsupervised relation features may provide meaningful insights into lymphoma classification. Published by the BMJ Publishing Group Limited.

    To develop expert systems for classification of follicular thyroid tumor at a preoperative stage. Fine needle aspiration biopsy of the thyroid gland with a histologic conclusion of follicular cancer and follicular adenoma were the object of the morphometric study. General sample size was 4500 nuclei and 3000 aggregates. Quantitative regularities of pathologic changes in thyrocyte nuclei and aggregates in follicular cancer and follicular adenoma were revealed. Threshold values and weighting coefficients of quantitative features of thyrocyte nuclei and aggregates characterizing cancer made the basis of the two expert systems. Expert systems included standard 2-D S-matrix containing threshold values of nuclei and aggregates in cancer and their weighting coefficients as well as 1-D scientific X-matrix designed for filling with quantitative features of the studied object. The diagnosis was verified by the value of a diagnostic index by means of comparing feature values in the corresponding elements of S- and X-matrices. After that, a diagnostic index was calculated taking into account the features' weighting coefficient. The developed expert systems based on a set of quantitative features of thyrocyte nuclei and aggregates will allow assessing the malignant potential of a follicular thyroid tumor at a preoperative stage.

    Non-Hodgkin lymphoma (NHL) is a diverse group of lymphoma comprises of divergent tumors with paradoxical clinical behaviors and potential difference in response to therapy. We conducted a data-base analysis on NHL patients to evaluate the clinico-epidemiological features and WHO spectrum of NHL in Pakistani patients. This descriptive study was conducted over a period of 5 years from January 2011 to December 2015 at Hematology department of Liaquat National Hospital. All NHL cases were diagnosed by morphology on H&E sections and Immunohistochemical profile according to WHO classification of lymphoid neoplasms. 184 histopathologically confirmed cases of NHL were identified. There were 139 males and 45 females, with a male to female ratio of 3: 1. The mean age was 48.5±16.0 years with the median age of 50 years. B symptoms were present in 80.4% of patients. Lymph node enlargement was present in 71.1% of the cases. 168 patients ad B-cell lymphoma (91.3%) and 16 patients had T-cell (8.6%) lymphoma. Overall 158 (85.8%) patients had aggressive lymphoma. Histopathologically, Diffuse large B-cell lymphoma constituted major subtype in 67.9%, followed by follicular lymphoma in 7.6% patients. Marginal lymphoma in 3.8%patients, 3.2% patients had mantle cell, 2.7% patients of anaplastic large cell and 2.1% patients each for Burkitt's lymphoma and T-cell rich lymphoma. In T cell neoplasm, peripheral T cell lymphoma and adult T cell lymphoma are the main variants accountable in 4.3% and 3.2% respectively. B cell lymphoma is more frequent than T cell lymphoma with diffuse large B-cell lymphoma being the commonest NHL. Our analysis shows that clinicopathological features of NHL are comparable to published data. However, aggressive lymphoma and predominance of B symptoms are more frequently seen.

    Advances in diagnostic imaging technology, especially functional imaging modalities like positron emission tomography (PET), have significantly influenced the staging and treatment approaches used for pediatric Hodgkin's lymphoma. Today, the majority of children and adolescents diagnosed with Hodgkin's lymphoma will be cured following treatment with noncross-resistant combination chemotherapy alone or in combination with low-dose, involved-field radiation. This success produced a greater appreciation of long-term complications related to radiation, chemotherapy, and surgical staging that prompted significant changes in staging and treatment protocols for children and adolescents with Hodgkin's lymphoma. Contemporary treatment for pediatric Hodgkin's lymphoma uses a risk-adapted approach that reduces the number of combination chemotherapy cycles and radiation treatment fields and doses for patients with localized favorable disease presentation. Advances in diagnostic imaging technology have played a critical role in the development of these risk-adapted treatment regimens. The introduction of computed tomography (CT) provided an accurate and non-invasive modality to define nodal involvement below the diaphragm that motivated the change from surgical to clinical staging. The introduction of functional imaging modalities, like positron emission tomography (PET) scanning, provided the means to correlate tumor activity with anatomic features generated by CT and modify treatment based on tumor response. For centers with access to this modality, PET imaging plays an important role in staging, evaluating tumor response, planning radiation treatment fields, and monitoring after completion of therapy for pediatric Hodgkin's lymphoma.

    When there's a diagnosis of follicular cyst. In front of lesions of advanced decay in deciduoud teeth about which is possible to presume chronical apical infection, we have to evaluate carefully the choice of treatment: pulpectomy or exodontia and the placement of a space maintainer. In this article there's a case in which a non-indicated pulpectomy was practised and caused a follicular cyst which is a menace to the formation and position of the unerupted permanent teeth. After the surgery we proceeded to exodontia and subsequently to place a space maintainer.

    Central nervous system (CNS) involvement by lymphoma is a complication associated, almost invariably, with a poor prognosis. The knowledge of the risk factors for CNS relapse is important to determine which patients could benefit from prophylaxis. Thus, patients with very aggressive lymphomas (such as lymphoblastic lymphoma or Burkitt's lymphoma) must systematically receive CNS prophylaxis due to a high CNS relapse rate (25-30%), while in patients with indolent lymphoma (such as follicular lymphoma or marginal lymphoma) prophylaxis is unnecessary. However, the question about CNS prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the most common type of lymphoma, remains controversial. The information available is extensive, mainly based on retrospective and heterogeneous studies. There seems that immunochemotherapy based on rituximab reduces the CNS relapse rate. On the other hand, patients with increased serum lactate dehydrogenase plus more than one extranodal involvement seem to have a higher risk of CNS relapse, but a prophylaxis strategy based only on the presence of these 2 factors does not prevent all CNS relapses. Patients with involvement of testes or breast have high risk of CNS relapse and prophylaxis is mandatory. Finally, CNS prophylaxis could be considered in patients with DLBCL and renal or epidural space involvement, as well as in those cases with MYC rearrangements, although additional studies are necessary.

    A retrospective review of 75 patients of malignant lymphoma treated at the Department of Otolaryngology, Kurume University Hospital, during the 10 years from 1971 to 1980 was carried out. In this study, the determinate cases consist of previously untreated 61 patients with histological diagnosis of malignant lymphomas. The results were seen as follows; (1) A patient of Hodgkin's disease, mixed cellularity (MC) in CS III, nodal lesion, was a 26-year-old male. He is currently alive 45 months after the initial treatment with no evidence of relapsing lesion. (2) In 60 patients with non Hodgkin's lymphomas, 1-, 2-, and 5-year cumulative survival rates calculated by the actuarial method were 65.5%, 54.8%, and 44.8%, respectively. (3) In patients with non-Hodgkin's lymphomas in early stages or of the Waldeyer's ring, prognosis was better. (4) Patients in advanced stages presented lower survival rate. (5) Diffuse lymphoma, plemorphic type showed the worst survival rate. (6) Among 31 deaths, 21(68%) were death from tumor dissemination, 5(16%) from complication, 2(6%) from unknown cause, 3(10%) from intercurrent disease. (7) Pulmonary complications, particularly, pneumonitis was the most serious complication in non-Hodgkin's lymphomas. (8) Relapse rate was 44% in early stages. Relapse occurred most frequently within 1 year, but there were some late relapses. (9) Two patients with non-Hodgkin's lymphomas of the Waldeyer's ring had a gastrointestinal involvement at relapse. (10) Lastly, we propose diagnostic and therapeutic protocols for the patients with malignant lymphomas. (author)

    Described are the review of the transplantation in the title (SCT), and the possible impact on its application and outcome of radio-immunotherapy (RIT) by new antibody drugs like ibritumomab tiuxetan (Ibr) and tositumomab (Tos), and of chemotherapy by purine analogs. Various regimens for the combination of auto-SCT, allo-SCT, chemotherapy and total body irradiation (TBI) have been used to treat the recurrent and progressive indolent lymphoma including follicular lymphoma (FL); however, their outcomes are still controversial. Introduction of new drugs like rituximab (Rit), Ibr and Tos has made it possible to extend the options of the regimen. For instance, in auto-SCT in FL, a high dose Rit therapy is used for in vivo purging to reduce tumor cell contamination of the graft instead of the exhausting, high-cost pretreatment for the in vitro purging with cyclophosphamide (CY)/TBI hitherto. In addition, RIT by Tos at the absorbed dose of 20-27 Gy in the critical organs with CY/VP16 combination is reportedly superior to CY/VP16/TBI. In allo-SCT where recurrence frequency is known low despite high mortality due to various complications, many regimens involving fludarabine/TBI have been also reported. Thus there has been neither clear standard for SCT in the lymphoma nor yet its prognosis after the therapy with new drugs described and the accumulation of their findings hereafter is important for future SCT application.
