PURPOSE To evaluate incidence, time trends, geographic distribution, clinicopathologic presentation features, and prognostic factors for survival and relapse in gastrointestinal (GI) non-Hodgkin's lymphomas (NHLs). PATIENTS AND METHODS Over a 9-year period (1983 to 1991), 2,446 new NHL cases were recorded in a Danish population-based NHL registry (Danish Lymphoma Study Group [LYFO]). Of these, 306 (12.5%) were GI NHL (175 gastric, 109 intestinal, and 22 both sites). LYFO registry data were used for incidence rate (IR) assessment, and time-trend and geographic distribution analysis. Relative risk (RR) values for survival and relapse were identified by multivariate analysis. RESULTS The mean annual, age-standardized IRs for gastric and intestinal NHL were 0.71/10(5) and 0.48/10(5) per year, respectively. Age-specific IRs for both localizations showed an exponential increase as a function of age. Time-trend analysis for the period 1983 to 1991 showed stable IRs for both localizations. Intestinal NHL was more frequent in males (male-to-female ratio, 2.0 v 1.3), and had a higher occurrence of disseminated disease, constitutional symptoms, high-grade histology, and T-cell phenotype (10% v 2%). Gastric NHL had more low-grade cases (38% v 19%), and almost all were of the mucosa-associated lymphoid tissue (MALT) type. The cause-specific 5-year survival rate was 63% for gastric NHL and 49% for intestinal NHL. The Musshoff staging system was an excellent discriminator between truly localized (stage I and II1) and disseminated cases (stage II2 to IV), particularly for gastric NHL, for which no survival difference was found between surgically and conservatively stage localized cases. CONCLUSION (1) No increase in the incidence of GI NHL was found over a 9-year observation period; (2) nonrandom spatial distribution of new GI NHL cases was observed; (3) factors that significantly increased the risk of death in gastric cases were presence of B symptoms (RR = 3.3), clinical stage is more than II1 (RR = 3.0), age more than 72 years (RR = 2.4), and elevated serum lactate dehydrogenase (s-LDH) level (RR = 2.0); and factors that increased the risk of death in intestinal cases were presence of B symptoms (RR = 3.2), age more than 58 years (RR = 2.8), and clinical stage more than I (RR = 2.1); (4) factors that significantly increased the risk of relapse in gastric cases were male sex and no radiotherapy in primary treatment; and in intestinal cases were T-cell phenotype and no surgery in primary treatment; (5) surgical staging, as opposed to thorough noninvasive staging, did not improve staging accuracy and final outcome in localized gastric NHL.

Abstract The advent of therapeutic monoclonal antibodies has enhanced the efficacy of NHL treatment. In recent years, these immuno-therapies have been increasingly used in therapy. We conducted a population-based study of NHL treatment practices in the US using a stratified random sample of patients diagnosed in 1999 with histologically confirmed NHL (n=939) residing in the geographic areas covered by the Surveillance, Epidemiology and End Results program. Blacks and Hispanics were over-sampled to obtain more stable estimates. Patients were followed for vital status through Dec 2001. We performed separate logistic regression analyses to study the potential factors associated with the likelihood of receiving chemotherapy, radiation therapy and the monoclonal antibody, Rituximab. Cox Proportional Hazards regression model was used to study the risk factors associated with survival time. We grouped histological subtypes into five broad categories: B-cell aggressive, B-cell indolent, T-cell generic, cutaneous T-cell, and mantle cell lymphomas. The majority of patients presented with B-cell aggressive or B-cell indolent lymphomas (n=828). Approximately 20% of patients received no therapy. Over 60% of patients received chemotherapy, either alone or in combination. 12% of patients received Rituximab and it was most frequently administered to patients in combination with chemotherapy, especially for patients with B-cell aggressive, B-cell indolent and T-cell generic lymphomas. Only 3% of patients participated in clinical trials. Age and gender were associated with the receipt of chemotherapy: people aged over 75 years, and males were less likely to have received chemotherapy (P=0.01). There were no significant associations between the likelihood of receiving Rituximab and the demographic and clinical factors analyzed. However, our results suggested that African-Americans and people aged over 75 years were less likely to have received immunotherapy. Twenty-four percent of patients received radiation with or without another therapy. When compared to patients with no symptoms at presentation, patients who presented with B-symptoms at diagnosis or those whose B-symptoms were unknown were less likely to have received radiation therapy (OR=0.32 and 0.47 respectively, P=0.0002). Approximately 50% of patients had died by the end of maximum the 3-year follow-up period. Both cause-specific and all-cause mortality was significantly associated with patient age, race/ethnicity, gender, marital status and co-morbid conditions, as well as histological subgroup. Hispanic and Black patients had higher risk of death from both NHL and all-cause (P<0.01) than their non-Hispanic white counterparts. Patients > 75 years, male patients, unmarried patients, or patients with B-symptoms had higher risk of death from either NHL or all-cause (p<0.01). This paper is the first population-based study examining the receipt of therapy for many histological subtypes of NHL. Future work will examine the impact of treatment on survival.

Abstract Introduction: Recently, early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) was identified as a subtype of T-cell ALL (T-ALL), with distinctive gene expression and cell marker profiles. Some reports revealed that ETP-ALL was associated with a high risk of remission induction failure and relapse. In precursor T-cell lymphoblastic lymphoma (T-LBL), the clinical features and prognosis of the ETP subtype are not clear yet. In this study, we analyzed the data obtained from patients of advanced stage T-LBL to clarify the prognosis of pediatric T-LBL according to the immunophenotypes, including the ETP subtype of LBL. Patients and methods: From November 2004 to October 2010, 136 children (aged 1–18 years) with newly diagnosed advanced stage LBL (stages III and IV) were eligible for the Japanese Pediatric Leukemia/Lymphoma Study Group ALB-NHL03 study. We analyzed their immunophenotyping data as well as the ETP subtype. The immunophenotype of T-LBL was classified into pro-T, pre-T, intermediate T, and mature T based on the European Group for the Immunological Characterization of Leukemias (EGIL) classification. The definition of ETP subtype LBL was based on a previous report from the Tokyo Children’s Cancer Study Group (Inukai et al, 2011) using a scoring system consisting of the following 11 markers: CD4, CD8, CD13, CD33, CD34, HLA-DR, CD2, CD3, CD4, CD10, and CD56. Both definitions were based on flow cytometric analysis. Results: In this analysis, 104 (76%) patients were diagnosed with T-LBL. Sufficient data to evaluate the EGIL classification was available for 40 out of 104 patients. The remaining patients could not be classified due to incomplete immunophenotypic data. There were 1, 9, 21, and 9 cases of Pro-T, pre-T, intermediate T, and mature T, respectively. The 3-year event-free survival (EFS) of pro-T/pre-T and intermediate T/mature T was 80.0 ± 12.7% and 76.7 ± 7.7%, respectively (P = 0.7586). For evaluating the ETP subtype of LBL, sufficient data, obtained by using the scoring system with 11 markers, was available for 40 patients. Eight (20%) and 32 (80%) patients were classified as having ETP and non-ETP subtype, respectively. Bone marrow involvement for patients with ETP and non-ETP subtype was observed in 7 (88%) and 11 (34%) cases, respectively (P = 0.014). Central nervous system involvement in patients with ETP and non-ETP subtype was observed in 2 (25%) and 0 cases, respectively (P = 0.036). Thus, stage IV classification was more frequently observed in patients with ETP subtype than in patients with non-ETP subtype (P = 0.014). The 3-year EFS of patients with ETP and non-ETP subtype were 75.0 ± 15.3% and 71.9 ± 8.0%, respectively. There was no significant difference in EFS between patients with ETP and non-ETP subtype (P = 0.8281). Conclusion: For 40 out of 104 T-LBL patients, sufficient data was available to evaluate the immunophenotype for EGIL classification and ETP subtype. There was no significant difference in EFS according to the immunophenotypic subtype of T-LBL. In contrast to T-ALL, ETP subtype in LBL was not statistically related to EFS in this analysis. Disclosures No relevant conflicts of interest to declare.

Abstract Introduction: LPHD is a rare disease which accounts for 3–8% of all Hodgkin cases. Patients with LPHD relapse frequently and freedom from treatment failure is not significantly improved by intensification of polychemotherapy or radiotherapy. The malignant cells of LPHD are CD20+ and therefore the anti-CD20 antibody rituximab (R) may have activity with fewer adverse late effects. Methods: This phase-II trial was initiated by the German Hodgkin Lymphoma Study Group (GHSG) to evaluate rituximab in patients with LPHD at first or higher relapse or progressive disease after at least one standard treatment. Histological slides were reviewed by a reference panel. Pts received 375mg/m2 of the anti-CD20 antibody rituximab once weekly for four weeks given as intravenous infusion in saline solution. Results: Between 1999 and 2004 we treated twenty-one pts. with CD20-positive Hodgkin’s lymphoma according to the study protocol. Fourteen patients had stage I/II disease at the time of study entry and all patients were in their first to third relapse (median 2). The initial diagnosis of LPHD was confirmed in 17/21 cases. The remaining cases were reclassified as HD transformed to T-cell rich B-cell lymphoma (2) or CD20-positive classical HD (2). The overall response rate was 90%. Time to progression was 31 months (ms). The median follow-up 58 ms. Both T-cell rich B-cell lymphoma are in continous remission (PR 51ms+, CR 61ms+). Conclusion: Single-agent therapy with rituximab is safe and showed high efficacy in relapsed LPHD. Therefore rituximab might be a non-toxic and efficient alternative treatment strategy compared to intensified chemo-and/or radiotherapeutic protocols in this young group of patients.
