Abstract
BACKGROUND Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease, and most available data on gastric MALT lymphoma (GML) come from clinical studies of selected patients treated in centres of excellence. AIMS To analyse the clinical features, management and survival of GML patients in a population-based study in France METHODS: All new cases of GML diagnosed between 2002 and 2010 in 11 French areas covered by cancer registries were included. Pathology reports were verified and, if necessary, reviewed by an expert pathologist. All clinical data were retrospectively collected from medical files and analysed using stata V. 14 software. RESULTS Four hundred and sixteen patients with confirmed GML (50% male, median age 67 years) were identified. Among them, 44 showed an early transformation into diffuse large B cell lymphoma and were considered to have had an initially missed high-grade lymphoma. At diagnosis, 76% of patients were at stage IE/II, and 24% at stage III/IV of the disease. Helicobacter pylori infection was found in 57% of the patients. Eradication treatment was administered to 76% of patients and complete remission (CR) was obtained in 39%. One hundred and ninety patients received at least one other treatment, including 10 already in CR after eradication. Altogether, CR was obtained in 70% of patients and the 5-year overall survival was 79% (95% CI [75-83]). CONCLUSIONS In comparison to clinical series, in the general population, GMLs are more frequently diagnosed at an advanced stage, their clinical management is heterogeneous, and there is a risk of misdiagnosis and overtreatment. These results highlight the necessity of following currently available guidelines in this field.

Comparative gene-expression profiling of the large cell variant of gastrointestinal marginal-zone B-cell lymphoma. Sci Rep 2017; 7:5963.

Abstract
Gastrointestinal (g.i.) large cell lymphoma is currently regarded as diffuse large B-cell lymphoma (DLBCL) despite a more favorable clinical outcome compared to other DLBCL. Cluster analyses on a transcriptome signature of NF-κB target genes of 30 g.i. marginal zone B-cell lymphomas (MZBL; 8 g.i. MZBL, 22 large cell MZBL - among them 9 with coexisting small cell component) and 6 DLBCL (3 activated B-cell like (ABC), 3 germinal center-like (GCB)) reveals a distinct pattern. The distinctiveness of large cell MZBL samples is further confirmed by a cohort of 270 available B-cell lymphoma and B-cell in silico profiles. Of the NF-κB genes analyzed, c-REL was overexpressed in g.i. MZBL. c-REL amplification was limited to 6/22 large cell MZBL including the large cell component of 2/9 composite small cell/large cell lymphomas, and c-Rel protein expression was found in the large cell compartment of composite lymphomas. Classification experiments on DLBCL and large cell MZBL profiles support the concept that the large cell MZBL is a distinct type of B-cell lymphoma.

Abstract
A 45-year-old woman with no symptoms underwent upper gastrointestinal endoscopy. A discolored area was noted at the greater curvature of the gastric upper body. Endoscopic ultrasonography demonstrated thickening of the second sonographic layer indicating that the depth of invasion was confined to the mucosa. A urea breath test and anti-Helicobacter pylori antibody test were negative. A computed tomography scan showed a consolidation at the right lung. Gastric biopsy and transbronchial lung biopsy (TBLB) demonstrated a monotonous proliferation of atypical small lymphocytes. A diagnosis of gastric marginal zone B cell lymphoma of mucosa-associated lymphoid tissue type (MALT lymphoma) was made. The clinical stage was stage IV. A genetic analysis showed rearrangement of the joining region of the immunoglobulin heavy chain gene and identical clones in both lesions. An API2-MALT1 fusion gene was detected in the gastric lesion. After H. pylori eradication treatment, combination treatment with rituximab plus CHOP (R-CHOP) was performed; 6 months later an endoscopy revealed complete disappearance of the lesion. Multiple gastric biopsies showed no infiltrating atypical lymphocytes. Similarly, the lesion in the lung showed complete remission (CR) on CT and TBLB. This report shows that a gastric MALT lymphoma located in the mucosa and disseminated to the lung maintained CR by R-CHOP.

Abstract
Population-based studies analyzing clinical implications of nodal versus extranodal (EN) presentation of diffuse large B-cell lymphoma (DLBCL) are scarce. We studied clinical differences and trends in incidence, treatment and survival of nodal and EN DLBCL in a population-based cohort. All patients newly diagnosed with localized (Ann Arbor stage [AAS] I and II) nodal (n = 5124) and EN (n = 4776) DLBCL, and primary mediastinal B-cell lymphoma (PMBL; n = 88), diagnosed between 1989 and 2010, were selected from the Netherlands Cancer Registry. Primary EN disease was correlated with older age and more favorable clinical stage (AAS I). The age standardized incidence rates for men with localized EN DLBCL, and for men and women with localized PMBL, increased significantly, whereas the age standardized incidence rates of all other subgroups remained stable. The stomach was the most common EN localization. Patients with EN disease received less chemotherapy and targeted therapy than their nodal counterparts, irrespective of age and period of diagnosis. Their 5-year overall survival (OS) was 48% vs. 54% in the nodal group, but in multivariate analysis primary extranodal presentation was not independently associated with inferior survival. This population-based study shows clinically relevant differences between localized nodal and EN DLBCL and PMBL. Since patients with EN were significantly less often optimally treated, we advocate better interaction between medical disciplines.

Abstract
Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is an indolent B-cell lymphoma, which is often localized in the stomach. It is characterized by typical morphology, immunology, cytogenetics and expression profile. The coexistence of a large B-cell lymphoma and a MALT lymphoma in the gastrointestinal tract is defined as a composite lymphoma (ComL) and, as we have previously shown, is almost always the consequence of secondary transformation of MALT lymphoma. Here, we have analyzed a panel of seven MALT lymphomas, seven ComL and thirteen large cell variants of marginal zone B-cell lymphomas (MZBL) using FISH for the detection of rearrangements of IGH, MALT1, BCL6, BCL10 and FOXP1 and immunohistochemistry for Bcl6, Bcl10 and FoxP1. Translocations involving IGH were found in 10/27 lymphomas including two cases with IGH-BCL6 fusion and one with IGH-BCL10 fusion; in 7/10 cases, the translocation partner was not identified. Bcl10 and FoxP1 protein expression was heterogeneous throughout the series. Genetic rearrangements of BCL6 and Bcl6 protein expression were found almost exclusively in the large cell components of the ComL and the large cell extranodal MZBL (p = 0.2093 and p = 0.0261, respectively). These findings suggest Bcl6 as a marker for transformation of MALT lymphoma.

Abstract
We conducted a retrospective analysis to evaluate the Musshoff staging system for high-grade primary gastric lymphoma (HG-PGL), particularly in those patients with stages IE and IIE localized diseases. One hundred twenty-six patients presented with stage IE or IIE diseases were retrospectively reclassified on the basis of a pretreatment CT examination as to whether there was lymph node involvement. A positive M1 node (by AJCC staging system) on pretreatment CT scanning was associated with poor clinical outcome for localized stage I or II patients.

Abstract
Differences in genetic origin between nodal and extranodal diffuse large B-cell lymphomas (DLBCL) exist. Using population-based data from the registry of the Danish Lymphoma Group, the present study is the first to analyse clinical implications of nodal versus extranodal presentation of DLBCL. Of 4786 newly diagnosed non-Hodgkin's lymphoma patients in a 16-year period, 1575 (33%) had DLBCL. The annual incidence rate was 2.9 per 100 000; 40% were extranodal. The clinical profile of patients with extranodal DLBCL was different from the nodal DLBCL patients. Extranodal DLBCL was associated with older age and poorer performance score, but also lower tumour burden. In extranodal DLBCL, 51% of the cases were stage I and 36% were stage IV, whereas the patients were relatively equally distributed between the four stages in nodal DLBCL. For stage I patients, extranodal DLBCL was independently associated with poor survival (P = 0.003). In contrast, among stage IV patients those with extranodal DLBCL survived longer (P = 0.009). We conclude that there are important clinical differences between nodal and extranodal DLBCL. The addition of these clinical results to the existing aetiological and genetic data suggests that the distinction between nodal and extranodal DLBCL is not only pathogenetically but also clinically important.

Abstract
The Comprehensive Cancer Centre West (CCCW) population based non-Hodgkin's lymphoma (NHL) registry contains information on all newly diagnosed NHL patients living in the region covered by the CCCW. Patients were entered from June 1st 1981 to December 31st 1989. Follow-up is still ongoing, median follow-up is 113 months (1-191 months) for patients alive. In this study, patient and tumor characteristics, data on patterns of care, response and (relative) survival are described. As follicular lymphomas and diffuse large B-cell lymphomas are the most frequently occurring NHL subtypes in the database, a separate analysis is performed to characterize the clinical picture of these disease entities in the CCCW population. Our data illustrate that NHL patients in the general population are substantially older than patients included in trials and hospital based series. Due to older age, treatment is withheld or adapted for a substantial number of patients. The resulting survival and relative survival rates are a reflection of these choices.

Abstract
The stomach is a common site of extranodal malignant lymphoma. Here we examined the clinicopathological features of 317 gastric B-cell lymphomas and characterized the differences among low-grade mucosa-associated lymphoid tissue (MALT) lymphomas (LG), high-grade MALT lymphomas (HG), follicular lymphomas (FL) and diffuse large B-cell lymphomas (DL). Cases included 126 DL, 71 HG, 98 LG, 10 FL, three Burkitt's lymphoma and nine of undefined type. The age range of patients was as follows: LG, 14-96 years (mean, 61.1); HG, 20-87 years (mean, 63.9); DL, 16-88 years (mean, 62.8); and FL, 54-76 years (mean, 65.5). There were no differences in age with respect to tumor type. There were more women patients with LG (female:male, 55:43), while males predominated among DL patients (54:72). The sexes were represented almost equally in HG cases (34:37). Histological findings, especially in DL tumors, correlated significantly to the gross appearance of mass formation. Dutcher bodies were encountered mainly in HG or LG cases. Our results showed no differences in age, sex or site of disease between LG, HG and DL tumors. However, the grade of malignancy correlated strongly to gross appearance. Dutcher bodies were important for the diagnosis of gastric MALT lymphoma.

Abstract
We hereby present a retrospective clinicopathological and immunohistochemical study of surgically resected primary gastrointestinal (GI) lymphoma with an analysis of parameters of potential prognostic relevance. From a larger series of 144 cases of primary GI lymphomas, we chose 61 cases with sufficient clinical follow-up (mean 60, range 1-219 months), classified either as extranodal marginal zone B-cell lymphoma of MALT type (MALT lymphoma) or diffuse large B-cell lymphoma (DLBCL), after having excluded other subtypes. In addition to conventional clinical and morphological parameters, the expression levels of Ki-67 (MIB-1), bcl-2 and p53 were evaluated for prognostic significance. Twenty-one (34.4%) cases were classified as pure low grade marginal zone B-cell lymphoma of MALT type, 12 (19.7%) cases as low grade MALT lymphoma with a high grade component (mixed type), and 28 (45.9%) cases as primary extranodal DLBCL. Most of the lymphomas (53/61; 86.9%) were localized in the stomach, 3 (4.9%) in the small bowel, 3 (4.9%) multifocal in both stomach and small intestine and 2 (3.3%) in the large bowel. MIB-1 expression in more than 30% of tumor cells was detected in 42 (68.6%), bcl-2 expression in 20 (32.8%) and p53 accumulation in more than 10% of neoplastic cells in 16 (26.2%) lymphomas. Both high Ki-67 expression and p53 accumulation were more prevalent in the DLBCL. 30 (49%) patients showed lymph node involvement at surgery, 14 (23%) patients suffered tumor recurrence, and 24 (38.5%) died during the follow-up period. Tumor recurrence occurred primarily in patients who had presented lymph node involvement (9/14, 64.3%). The 5-year survival rate was 66.1% for all patients. Important prognostic factors for overall survival were tumor stage (p < .004) and p53 accumulation (p < .05) in univariate analysis, and tumor stage in multivariate analysis (p < .001). Although p53 accumulation did not reach statistical significance in our small study group, it may be both important in the transformation of low grade MALT lymphoma and an indicator for aggressive behavior in high grade tumors.

Abstract
It is debated whether non-Hodgkin's lymphomas originating in Waldeyer's ring (WR NHL) behave as NHL originating in lymph nodes or share common features with extranodal lymphomas originating in mucosa associated lymphatic tissue (MALT). We analyzed data from a population based NHL registry on patterns of dissemination at diagnosis, response to treatment, patterns of failure and survival of 77 primary Waldeyer's ring Non-Hodgkin's lymphomas (WR NHL) patents. Data of completely staged patients with diffuse large cell lymphomas (DLCL) originating in WR (n=44) were compared with those of patients retrieved from the same registry with DLCL originating in lymph nodes or stomach (the latter as prototype of a lymphoma originating in MALT). Primary WR NHL had favorable risk scores according to the International Prognostic Index (IPI), and responded well to therapy: a complete response (CR) rate of 74% was observed. Disease free survival (DFS) and overall survival (OS) were poor, however (47% and 31% at 10 years, respectively). The comparison of DLCL originating in WR, lymph nodes and stomach revealed that WR and gastric NHL patients shared a restricted pattern of dissemination at diagnosis, in contrast to patients with DLCL originating in lymph nodes. Although not all patients were completely restaged at relapse, analysis of patterns of failure suggested that the gastro-intestinal tract is a preferential site for recurrences, both for WR and gastric DLCL patients. CR rates of WR, nodal and gastric DLCL patients were 77%, 55% and 55% respectively (P=0.03), OS of the three patient subgroups did not differ (33%, 27% and 37% at 10 years). DFS of WR DLCL patients was similar to nodal DLCL patients but inferior to gastric DLCL patients (47%, 48% and 73% at 10 years respectively, P=0.006). After Cox regression analysis the relative relapse risk for patients with WR DLCL when compared to patients with DLCL originating in lymph nodes was 2.01 (C.I. 0.99-4.01, P=0.05), and 3.46 (C.I. 1.32-9.00, P=0.01) when compared to patients with gastric DLCL. The clinical picture of primary WR NHL emerging from this population based study is in agreement with data form hospital based studies. In the comparison of WR DLCL, nodal DLCL and gastric DLCL, the observed patterns of dissemination suggest similarities between WR DLCL and gastric DLCL. The frequent relapses after CR observed for WR DLCL patients, however, indicate that these lymphomas clinically behave as nodal DLCL, and should be treated accordingly.

Abstract
Expression of adhesion molecule in low-grade B-cell mucosa-associated lymphoid tissue (MALT) lymphoma of the gastrointestinal tract has been reported in recent years, but these reports have primarily focused on low-grade gastrointestinal MALT lymphoma. In this study, we examined the lymphocytic homing receptor alpha4beta7 integrin, L-selectin, and VLA-4 and mucosal addressin cell adhesion molecule-1 (MAdCAM-1) in low-grade lymphoma of the gastrointestinal tract and other organs such as the ocular adnexa and thyroid. We also observed changes in the expression pattern associated with high-grade transformation. Neoplastic cells in the gastrointestinal low-grade lymphoma and the low-grade component of high-grade MALT lymphoma were found to be alpha4beta7 integrin(+), L-selectin(+), whereas the gastrointestinal high-grade component and diffuse large B-cell lymphoma were found to be alpha4beta7 integrin(-), L-selectin(-). High endothelial venules in the gastric MALT lymphomas expressed MAdCAM-1. In the ocular adnexa low-grade MALT lymphoma, most cases were alpha4beta7 integrin(-), L-selectin(+); and in the thyroid, most cases of both low- and high-grade MALT lymphoma were alpha4beta7 integrin(-), L-selectin(-). These findings show that alpha4beta7 integrin and L-selectin may play an important role in the lymphocyte homing of gastrointestinal low-grade MALT lymphoma and in the loss of alpha4beta7 integrin expression throughout the course of high-grade progression.

Abstract
Since mucosa-associated lymphoid tissue (MALT) lymphoma was defined in the mid-1980s as a clinicopathologic entity, many sets of data on pathological, biological and clinical aspects have been generated. In particular, the finding that this process was responding well to antibiotic treatment fueled interest in it and has led to several clinical trials. This overview deals with epidemiological and prognostic aspects and identifies important questions which need to be answered before data from different sources can be compared. Incidence figures of gastric MALT lymphoma vary between countries and parallel the numbers of all non-Hodgkin's lymphoma. The incidence does not parallel the occurrence data of Helicobacter pylori infection. Incidence figures are highly dependent on the definition used for MALT-type primary gastric lymphomas. Several studies show that some prognostic factors are relevant, for instance stage and grade, whereas other factors such as the International Prognostic Index or treatment are not. These studies do not include the recently introduced antibiotic therapy. The inclusion of recent insights in biology and the treatment of gastric MALT lymphomas in prospective clinical studies will soon answer some of the main questions posed.

Abstract
AIMS Gastric MALT (mucosa-associated lymphoid tissue) lymphoma is now recognized as a distinct entity within extranodal non-Hodgkin's lymphoma. The purpose of this study was to describe the radiographic findings in low grade gastric MALT lymphoma. MATERIALS AND METHODS We retrospectively reviewed the radiographic findings in 22 cases of low-grade gastric MALT lymphoma. The study group consisted of 15 men and seven women (median age 68 years, range 41-91 years). Lesions were designated as infiltrative or polypoid by consensus of two radiologists. Polypoid lesions were categorized by number and size. Anatomical site within the stomach and presence of transpyloric or oesophagogastric extension was determined for each case. The presence of abdominal lymphadenopathy was categorized as regional or distant. The presence of Helicobacter pylori was determined from endoscopic and surgical biopsies. RESULTS Computed tomography (CT) revealed abnormalities of the stomach in 19 cases of the 21 in which it was performed. There were 14 infiltrative lesions and five polypoid lesions. Of the 14 infiltrative lesions, the mean gastric wall thickness was 2.2 cm (range 0.8-6.0 cm). There were three single and two multiple polypoid lesions (mean size 2.2 cm, range 1. 5-2.7 cm). Transpyloric extension was observed in two cases and oesophagogastric extension in one. Abdominal lymphadenopathy was observed in 10 of 21 patients. Helicobacter pylori was found in 19 of 22 cases (86%). CONCLUSION Low grade B cell gastric MALT lymphomas present with an infiltrative form on CT in about three-quarters of cases and a polypoid pattern in the remainder. Abdominal lymphadenopathy is seen in approximately one-half of cases. There is a high association with Helicobacter pylori.

Abstract
AIMS To investigate the clinicopathological differences among gastric low grade MALT lymphomas (low MALT), large B cell lymphomas with low grade components (secondary high grade MALT lymphomas, high MALT), and diffuse large B cell lymphomas without low grade features (primary high grade MALT lymphomas, DLL). METHODS Clinicopathological and morphological characters of 126 gastric lymphoma cases were studied: 82 cases of low MALT lymphoma including 40 that were surgically resected, 17 cases of high MALT lymphoma including 13 surgically resected, and 27 cases of DLL including 12 surgically resected. RESULTS Age ranges were as follows: low MALT lymphoma, 34 to 85 years (mean 59.9); high MALT lymphoma, 53 to 88 years (mean 68.5); DLL, 29 to 83 years (mean 62.3). The average age for low and high MALT lymphomas was significantly different (p < 0.05), but there were no differences in other comparisons. There was a female predominance of low MALT lymphoma patients (female to male ratio, 47/35), while for high MALT patients the ratio was almost even (8/9), and for DLL patients there was a male predominance (11/16). Examination of surgically resected material showed that MALT lymphomas had a wider distribution in the gastric wall than DLL. CONCLUSIONS The findings suggest that at least some of the high grade gastric lymphomas, especially in patients younger than the fifth decade, do not originate from high grade transformation of low MALT lymphomas. It seems to take about one decade at least for high grade transformation of low MALT lymphomas.

Abstract
BACKGROUND Variations in diagnostic criteria and staging procedures in cancer patients have important consequences for patient selection and often preclude meaningful comparison of published series. In gastric lymphoma, these effects will play a role, since diagnostic criteria are controversial. Moreover, staging procedures and therapeutic choices are influenced by insights from different clinical specialisms. METHODS To review the management of gastric lymphoma, formatted questionnaires were mailed to leading institutes with a special interest in this field in Europe, the United States and Japan. RESULTS Nineteen centers agreed to contribute. Minimum histological criteria varied among pathologists with a notable influence of the classification system used in the different countries. Detailed evaluation of the lymphoma distribution in the gastric wall and routine staging of the GI-tract differed between groups leaded by medical oncologists and gastroenterologists. This results in basically different patient selections and bias in treatment outcome. Similar effects were recorded for the role of gastric resection and radiotherapy. CONCLUSIONS This study gives insight in the basis of the decisions that result in different approaches in the management of gastric MALT-NHL and in the effects for patient selection and treatment results and may help in the design of future clinical trials.

Abstract
BACKGROUND Primary extranodal lymphomas (EN-NHLs) are a heterogeneous category of tumors that are considered to be different from primary nodal non-Hodgkin's lymphomas (N-NHLs). To what extent these differences have clinical implications is currently not very clear, because knowledge of EN-NHL as a separate group is limited. METHODS Using data from the Comprehensive Cancer Centre West (CCCW) population-based NHL registry in the Netherlands, N-NHL and EN-NHL patients were compared to determine differences in characteristics at diagnosis, responses to treatment, patterns of failure, and survival. RESULTS At presentation, EN-NHL patients had poorer performance scores and more often bulky tumors compared with N-NHL patients, resulting in poorer responses to treatment (complete response rates were 72% and 84%, respectively; P=0.04) and inferior 5-year overall survival (49% and 63%, respectively; P=0.003). Among EN-NHL patients, considerable variations in response, survival, and relapse rates were observed, with gastric NHL patients having the best and central nervous system NHL patients having the worst prognosis (66% and 7% 5-year overall survival, respectively). Relapse rates for N-NHL and EN-NHL patients did not differ (39% and 36% 5-year relapse rates, respectively), whereas among EN-NHL patients considerable differences in relapse rates were noted. Relapses among N-NHL patients were mainly found in nodal sites, whereas recurrent disease in EN-NHL patients was mainly found in extranodal sites. CONCLUSIONS In this population-based study, Stage I EN-NHL patients as a group had a poorer prognosis than N-NHL patients. However, among EN-NHL patients, considerable differences in response, relapse risk, and survival were observed. The failure analysis conducted in this study suggests that patterns of dissemination for N-NHL and EN-NHL are different.

Abstract
BACKGROUND This study was conducted to determine whether the paranasal extension of a primary non-Hodgkin's lymphoma (NHL) of the nasal cavity has any deleterious effect on patient outcome. METHODS One hundred and seventy-five patients with previously untreated nasal NHL were reviewed. There were 2 with low grade, 107 with intermediate grade, 17 with high grade, and 49 with unclassifiable lymphomas. In 48 cases the immunophenotype was available and 46 were T-cell lymphoma. According to the Ann Arbor system, there were 133 patients with Stage IE, 28 with Stage IIE, 4 with Stage IIIE, and 10 with Stage IVE lymphomas. Stage IE was subdivided into limited Stage IE (i.e., confined to the nasal cavity [67 patients]) or extensive Stage IE (i.e., presenting with extension beyond the nasal cavity [66 patients]). For patients with limited Stage IE disease the treatment of choice was radiotherapy with or without chemotherapy. In patients with extensive Stage IE disease, treatment was comprised of a combination of chemotherapy and radiotherapy or radiotherapy alone. For patients with a more advanced stage of disease (IIE-IVE), chemotherapy was an integral part of the treatment and was completed by irradiation, especially for patients with Stage IIE disease. RESULTS The actuarial overall survival (OS) and disease free survival (DFS) rates at 5 years for the whole group were 65% and 57%, respectively. The 5-year OS and DFS rates were influenced by stage, with a gradual decrease from 75% and 68% for Stage IE disease to 35% and 28% for Stage IIE disease, and 31% and 19% for Stage IIIE/IVE disease. Patients with limited Stage IE disease survived significantly longer (90% 5-year OS) compared with those with extensive Stage IE disease (57% 5-year OS; P < 0.001). For 67 patients with limited Stage IE disease, the 5-year OS was 89% with radiotherapy alone and 92% with radiotherapy and chemotherapy, whereas for 66 patients with extensive Stage IE disease, the 5-year OS was 54% with radiotherapy and 58% with combined modality therapy or chemotherapy (P > 0.05). CONCLUSIONS The prognosis of patients with primary NHL of the nasal cavity is stage dependent. In this large cohort of Stage IE patients, it was demonstrated that the paranasal local extension was a significant prognostic factor associated with poorer treatment outcome. The authors believe that Ann Arbor Stage IE should be subclassified further into limited and extensive Stage IE. The addition of chemotherapy did not appear to modify significantly the survival of patients with either limited or extensive Stage IE disease. The extranodal progression observed in patients with extensive Stage IE and Stage IIE-IVE disease clearly illustrates the need for improvement of systemic treatment.

Abstract
Gastric low-grade mucosa-associated lymphoid tissue (MALT) lymphoma is a unique disease. A vast majority of lymphoma cells are centrocyte-like cells or resemble monocytoid B cells, and occasionally show plasmacytic differentiation. Immunophenotypical and immunogenotypical examinations have indicated that they are in the differentiation stage of memory B cells, whose normal counterparts are marginal zone lymphocytes or monocytoid B cells in the lymphoid tissues. It arises from chronic gastritis closely associated with Helicobacter pylori (H. pylori) infection. Mucosa-associated lymphoid tissue lymphomas of other organs are also based on acquired MALT associated with chronic inflammation or autoimmune diseases. Interestingly, the majority of gastric low-grade MALT lymphomas regress by the eradication of H. pylori. The lymphoma cells, however, are not derived from B cells reacting with H. pylori itself but from autoreactive B cells. Although the mechanism of their oncogenesis has not been clarified, previous data suggest that autoreactive B cells proliferate in response to H. pylori-specific T cells, presumably with some cytokines. The genetic instability of such B cells then induces chromosomal abnormalities including trisomy 3 and/or other genetic changes. These B cells have the ability of autonomic proliferation and, even so, they might be sensitive to T cell stimuli. Low-grade gastric lymphomas occasionally progress to high-grade malignancy. The high-grade component of MALT lymphomas are composed of large-sized lymphoma cells that are morphologically indistinguishable from nodal large B cell lymphomas. This high-grade transformation is associated with p53 abnormalities or Bcl-6 overexpression. Gastric MALT lymphoma may provide a useful model in understanding multistep lymphomagenesis.
