Abstract
OBJECTIVE Surgery is an effective clinical approach that has been used for the treatment of gastric lymphoma. However, its specific effect on the prognosis of patients with gastric lymphoma remains largely unknown. The current meta-analysis aimed to identify the effect of surgery on the prognosis of gastric lymphoma. METHODS We searched the MEDLINE, Embase, and Cochrane Central databases to obtain relevant studies investigating the influence of surgery on overall survival (OS) and relapse-free survival (RFS). We extracted the hazard ratios (HRs) and associated 95% confidence intervals (CIs) of each included report for pooled analysis. We assessed heterogeneity (I2 statistic) and funnel plots to select the data models and evaluate publication bias. RESULTS Ultimately, we included 12 studies containing 26 comparisons in the current quantitative meta-analysis. The analysis revealed that surgery had no significant effect on OS (HR .83, P = .13) or RFS (HR .78, P = .08). However, subgroup analysis revealed that the effect of surgery on OS differed significantly between the surgery plus conservative therapy subgroup and the conservative therapy alone groups, with HR = .69 (P = .01). No significant publication bias was detected regarding the main outcomes. CONCLUSION Surgery had a limited effect on the prognosis of patients with gastric lymphoma. However, the use of surgery as an additional therapy may confer potential benefits. This was an interesting research direction, and additional high-quality, large-scale randomized controlled trials should be conducted.

Abstract
Patients with primary gastrointestinal (GI) lymphoma are at risk of GI perforations. Therefore, we aimed to investigate the prognostic impact of non-traumatic GI perforations. 54 patients with a histologically confirmed diagnosis of primary GI lymphoma were included. Non-traumatic lymphoma perforation occurred in ten patients (19%). Perforations occurred only in patients with aggressive B-cell lymphoma. In patients with aggressive B-cell lymphoma, the median overall survival (mOS) was 52 months (95% CI 9.88-94.12) and 27 months (95% CI 0.00-135.48) in patients with and without GI perforation, respectively. The median progression-free survival (mPFS) was 30 months (95% CI 5.6-54.4) in patients with GI perforations. In patients without lymphoma perforation, mPFS was not reached. Both mOS and mPFS did not significantly differ. In conclusion, despite the need for emergency surgery and delay in lymphoma-directed treatment, lymphoma perforation did not negatively impact our study population's OS or PFS.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most frequent cancer types in Mexico. The primary method used as a treatment is surgical resection. The role of surgery in increasing survival is controversial. This study aimed to determine whether surgical resection increases the survival of patients with GC in a Mexican population. METHODS A systematic review of literature searches (Evidence-based MEDLINE/PubMed, Web of Science, Cochrane Library, and SciELO) and meta-analysis were performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis criteria. The published articles from 2000 to the current time were divided into cross-sectional and randomized studies. The inclusion criteria were survival, surgical resections, patients treated in Mexico, and primary GC. The effect estimation was calculated using the risk ratio (RR). The random-effects model and a confidence interval (CI) of 95% were used. RESULTS The RR of the pooled studies was 1.09 (95% CI, 0.71-1.67). RR of 0.82 (95% CI, 0.63-1.07) was obtained in cross-sectional studies, and randomized studies showed a RR of 2.08 (95% CI, 0.25-17.07). CONCLUSION This work is the first systematic study that assesses the role of surgery on the survival of patients with GC in the Mexican population, the results showed that surgical resection did not improve survival in patients with GC.

Abstract
Primary gastric lymphoma (PGL) is a rare clinical entity accounting for the majority of extra-nodal non-Hodgkin lymphoma (EN-NHL). The most common histological subtype is the primary gastric diffuse large B-cell lymphoma (PG-DLBCL) with a media age of 50-60 years old, mostly in male. Pathogenesis is often related to some bacterial infection such as Helicobacter pylori (H. pylori) infection. However, due to various available staging system, there is still no consensus on the staging of PG-DLBCL. The international prognostic index (IPI) is the most valuable used for the stratification of almost all subtype of NHL and as well as for PG-DLBCL. As for treatment strategies, surgery, chemotherapy, radiation therapy and antibiotic therapy in various combinations have been applied in clinical treatment. There are a few well-known prognostic factors and some of them may constitute prognostic models. Due to the increasing incidence of this neoplasm, it is necessary for clinicians to make deep insight of the diagnosis, staging, treatment and prognostic factors of PG-DLBCL.

Abstract
PURPOSE Advanced gastric cancer (AGC) and primary gastric lymphoma (PGL) are the two most common malignant tumors of the stomach. Conventional imaging examinations have difficulty distinguishing the two. This study explored the values of multiple parameters and visual assessment of 18F-fluorodeoxyglucose(18F-FDG) uptake heterogeneity of positron emission tomography/computed tomography(PET/CT) for differentiating between AGC and PGL. METHODS This retrospective study included 70 AGC and 26 PGL patients, all of whom had undergone 18F-FDG PET/CT before treatment. We analyzed the differences between AGC and PGL in the distribution of metastatic lesions and multiple metabolic parameters, including the maximum standardized uptake value (SUVmax), SUVmax/maximal thickness(THKmax), metabolic tumor volume and total lesion glycolysis (TLG). In addition, 18F-FDG uptake heterogeneity was visually assessed using a visual scoring method and a method of measuring SUVmax differences (SUVmax-d). RESULTS The most common metastasis of AGC patients were liver, bone, peritoneal and proximal lymph nodes; PGL patients had fewer peritoneal metastases and lymph node metastasis could appeared to be "skip metastasis." The metabolic parameters-SUVmax, SUVmax/THKmax and TLG-were higher in patients who had PGL, especially in diffuse large B-cell lymphoma (DLBCL). In the visual assessment of 18F-FDG uptake heterogeneity, the measurements of SUVmax-d in PGL were significantly higher than in AGC. Receiver operating characteristics curve analysis suggested that SUVmax has the highest comprehensive diagnostic efficiency due to having the highest value of area under the curve and the highest accuracy (77.2%). CONCLUSION 18F-FDG PET/CT had a high diagnostic efficiency for discrimination of AGC and PGL, especially between DLBCL and other pathological subtypes. Visual assessment used to evaluate 18F-FDG uptake heterogeneity could help to distinguish the two types of tumors. In addition, our innovative method of measuring the heterogeneity of 18F-FDG uptake-namely, SUVmax-d-could contribute to identification of the two tumor types and should have its significance clarified by future studies.

Abstract
Objective: This study aimed to explore the prognostic factors for primary gastric diffuse large B-cell lymphoma (PG-DLBCL). Materials and Methods: This retrospective study analyzed 72 PG-DLBCL patients between January 2012 and December 2017 in the Shanxi Cancer Hospital of Shanxi Medical University to identify the different prognostic factors in PG-DLBCL. The clinical features, treatment, and follow-up information were analyzed. Results: The low CD4:CD8 ratio group (median subsequent overall survival [OS]: 36.06 months; 95% confidence interval [CI]: 25.73-46.40) showed a significant decrease in subsequent OS compared to the normal group among PG-DLBCL patients who were newly diagnosed and did not receive rituximab (median OS: 52.58 months; 95% CI: 44.18-60.97; p=0.029). Event-free survival status 24 months after the date of diagnosis (EFS24) also decreased significantly in the low CD4:CD8 group (median EFS24: 16.27 months; 95% CI: 13.09-19.45) compared to the normal group (median EFS24: 20.34 months; 95% CI: 17.05-23.63; p=0.014). Multivariate analysis showed that low CD4:CD8 at diagnosis was an independent poor prognostic factor for subsequent OS and EFS24. Conclusion: Our data suggest that identifying prognostic factors, especially host immunity, may provide useful information for assessing prognosis or clinical management.

Abstract
RATIONALE The specific pathogenesis of the diffuse large B-cell lymphoma(DLBCL)is still indefinite and argumentative. It is known that DLBCL is the most common type of non-Hodgkin's lymphomas (NHL). A lot of cases of DLBCL such as primary gastric diffuse large B-cell lymphoma(PG-DLBCL) are reported. However, primary intestinal diffuse large B-cell lymphoma(PI-DLBCL) is unusual. PATIENT CONCERNS We present a case of a 57-year-old male diagnosed in the Gastroenterology Department, which presented a bleeding duodenal ulcer with irregular borders. DIAGNOSES The immunohistochemical staining showed: CD20(+++), CD10(+) and Ki-67>40%. INTERVENTIONS The patient was successfully treated by Poly-chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vindesine and prednisolone). OUTCOMES After 6 courses of chemotherapy treatment, the duodenal ulcer was completely healed by reviewing the UGIE. LESSONS Our report might give further strength to avoiding the erroneous and missed diagnosis for PI-DLBCL which is different from common duodenal ulcer.

Abstract
Mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent lymphoma with good prognosis and variable fluorine-18 fluorodeoxyglucose (18 F-FDG) avidity. Many possible prognostic factors have been investigated with controversial results, but the possible prognostic role of 18 F-FDG positron emission tomography/computed tomography (PET/CT) remains unclear. Our aim was to evaluate the prognostic impact of qualitative and semiquantitative baseline PET/CT parameters on outcome of MALT lymphoma. We retrospectively enrolled 161 patients with histologically confirmed MALT lymphoma who underwent 18 F-FDG PET/CT before any treatment. PET images were qualitatively and semiquantitatively analyzed by measuring the maximum standardized uptake value body weight (SUVbw), lean body mass (SUVlbm), body surface area (SUVbsa), metabolic tumor volume (MTV), and total lesion glycolysis (TLG). The Kaplan-Meier method was used to estimate the progression-free survival (PFS) and overall survival (OS) times. Cox regression models were performed to determine the relation between PET/CT features and OS and PFS. Ninety-eight patients had positive 18 F-FDG PET/CT showing 18 F-FDG uptake (mean SUVbw, 10.1; SUVlbm, 7.2; SUVbsa, 2.7; MTV, 88.8; and TLG, 526); the remaining 63 were not 18 F-FDG avid. 18 F-FDG avidity was significantly correlated with tumor size and Ki-67 score. Relapse/progression of disease occurred in 47 patients with an average time of 40.2 months; death occurred in 12 patients with an average of 59 months. At a median follow-up of 62 months, median PFS and OS were 52 and 62 months, respectively. Advanced tumor stage and extragastric site were demonstrated to be independent prognostic factors for PFS, while only tumor stage for OS. Instead, PET/CT parameters were not related to survival, despite positive correlation at univariate analysis between MTV and TLG with PFS and positive PET/CT with PFS and OS. In conclusion, a 61% rate of PET avidity in biopsy-confirmed MALT lymphoma was found, and it was correlated with tumor size and Ki-67 score. Only tumor stage and localization were independently correlated with PFS and OS.

Abstract
Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma and represents a wide spectrum of disease, ranging from indolent low-grade marginal zone lymphoma or mucosa-associated lymphoid tissue (MALT) lymphoma to aggressive diffuse large B-cell lymphoma. The PGL is a relatively rare cancer and easily misdiagnosed due to its unspecific symptoms of the digestive tract. The medical literature and ongoing clinical trials were reviewed on the clinical presentation, diagnosis, prognosis, prevention, and treatment of PGL. Primary gastric lymphoma is an event in the course of cancer with a variable clinical presentation and a wide differential diagnosis. Chronic gastritis secondary to Helicobacter pylori (H pylori) infection has been considered a major predisposing factor for MALT lymphoma. Magnetic resonance imaging and endoscopic ultrasonography have helped in staging of these cancers. The clinical course and prognosis of this disease are dependent on histopathological subtype and stage at the time of diagnosis. A global therapeutic approach to the cure of PGL has completely changed over the past 10 years, including innovative and conservative options to reduce treatment toxicity. Due to the rarity of PGL, many aspects of this neoplasm are still controversial. The incidence of this disease is increasing, making it necessary for clinicians to understand the clinical symptoms, workup, and treatment of these lymphomas.

Abstract
This retrospective study aimed to investigate clinical characteristics and prognostic factors in patients with primary gastrointestinal lymphoma (PGIL) of Chinese population.From January 2001 to December 2015, 137 patients diagnosed with PGIL were recruited. The clinical features, treatment, and follow-up information were analysed.The median patient age was 62.3 years. With 18.47 months follow-up, the 2-year progress-free survival and overall survival rate was 74.9% and 75.5%, respectively. The overall response rate was 33.6%. Age≥60 years, advanced Lugano staging (≥stage IIE), elevated lactate dehydrogenase (LDH) levels, ≥2 extra-nodal involved sites, National Comprehensive Cancer Network International Prognostic Index (NCCN-IPI)≥4, Ki-67≥50% were associated with worse prognosis in univariate analysis (P < .05). By multivariate analyses, we determined that the involvement of extra-nodal involved sites was the only statistically significant poor prognostic factor in PGIL.Age, staging, LDH levels, NCCN-IPI, Ki-67 especially involvement of multiple extra-nodal sites were associated with poor overall survival of PGIL.

Abstract
There are no widely accepted prognostic indices for extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT). This study aimed to develop and validate a specific prognostic tool to personalize and optimize treatment of patients with MALT lymphoma. A prognostic index was built by Cox regression (stepwise selection) using data from 401 patients enrolled in the international randomized International Extranodal Lymphoma Study Group 19 (IELSG-19) trial (NCT 00210353). A validation set, including 633 patients, was obtained by merging 3 independent cohorts of MALT lymphoma patients. The 3 individual features maintaining the greatest prognostic significance for event-free survival (EFS, the main endpoint of the IELSG-19 trial) were age ≥70 years (hazard ratio [HR], 1.72; 95% confidence interval [CI], 1.26-2.33), Ann Arbor stage III or IV (HR, 1.79; 95% CI ,1.35-2.38), and an elevated lactate dehydrogenase level (HR, 1.87; 95% CI, 1.27-2.77). The prognostic index (MALT-IPI) constructed using these 3 parameters identified 3 groups: low, intermediate, and high risk (corresponding to the presence of 0, 1, or ≥2 of these factors, respectively). The 5-year EFS rates in the low-, intermediate-, and high-risk groups were 70%, 56%, and 29%, respectively. The MALT-lymphoma International Prognostic Index (MALT-IPI) also significantly discriminated between patients with different progression-free, overall, and cause-specific survival. The prognostic utility was retained in gastric and nongastric lymphomas, in each treatment arm (chlorambucil, rituximab, and rituximab plus chlorambucil), and was confirmed in the validation set. The new index, MALT-IPI, is a simple, accessible, and effective tool to identify MALT lymphoma patients at risk of poor outcomes. It may help define appropriate treatment approaches for individual patients.

Abstract
This study evaluated the clinical features, treatment and prognosis in Chinese patients with histological transformation (HT) from gastric mucosa-associated lymphoid tissue lymphoma to gastric diffuse large B-cell lymphoma. We reviewed the medical records of 71 patients diagnosed with HT between 2001 and 2013, retrospectively. Patients had a median age of 56 years. The ratio of sex (male:female) was 1.3:1. The clinical course was often insidious, lacking specific clinical presentation. Macroscopically, the antrum was the most commonly involved site. Thirty-one patients (45%) presented at stage I, and 25 (35%) presented with local (18/71, 25%) or distant (7/71, 10%) nodal involvement. There were also stage IIE (9/71, 12%) and stage IV (6/71, 8%) patients with advanced stages. For all 71 patients, the 5-year progression-free survival (PFS) and overall survival (OS) estimates were 50 and 56%, respectively. There was no statistical difference in 5-year PFS and OS estimates between patients receiving Helicobacter pylori (H. pylori) containing eradication (HPE) (p=0.189) and those receiving non-HPE (p=0.359). Upon the Cox regression model, advanced stages were the only independent prognostic factors associated with shorter PFS, and m-IPI was independently associated with shorter PFS and OS. There was no specific clinical manifestation for patients with HT. HPE is thus a promising therapeutic approach for such patients. Moreover, advanced stages and m-IPI significantly influenced patient outcome.

Abstract
Background The clinical course of gastric lymphoma is heterogeneous and clinical symptoms and some factors have been related to prognosis. Objective The present study aims to identify prognostic factors in gastric diffuse B-cell non-Hodgkin lymphoma diagnosed and treated in different countries. Methods A consecutive series of gastric diffuse B-cell non-Hodgkin lymphoma patients diagnosed and treated in Brazil, Portugal and Italy, between February 2008 and December 2014 was evaluated. Results Of 104 patients, 57 were female and the median age was 69 years (range: 28–88). The distribution of the age-adjusted international prognostic index was 12/95 (13%) high risk, 20/95 (21%) high-intermediate risk and 63/95 (66%) low/low-intermediate risk. Symptoms included abdominal pain (63/74), weight loss (57/73), dysphagia (37/72) and nausea/vomiting (37/72). Bulky disease was found in 24% of the cases, anemia in 33 of 76 patients and bleeding in 22 of 72 patients. The median follow-up time was 25 months (range: 1–77 months), with 1- and 5-year survival rates of 79% and 76%, respectively. The multivariate Cox Regression identified the age-adjusted international prognostic index as a predictor of death (hazard risk: 3.62; 95% confidence interval: 2.21–5.93; p-value <0.0001). Conclusions This series identified the age-adjusted international prognostic index as predictive of mortality in patients treated with conventional immunochemotherapy.

Abstract
Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL.From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed.In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4.High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not in the MALT type. Recently, conservative treatment is becoming more preferred approach in patients with PGL.

Abstract
The diagnosis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma is difficult owing to its non-specific symptoms and various endoscopic findings. Treatments such as radiotherapy (RT) for localized and chemotherapy (CT) for advanced stages of the disease are employed. The aim of the present study was to examine the clinical characteristics and prognostic factors of Helicobacter pylori (H. pylori) eradication (HPE) in patients with gastric MALT lymphoma. The medical records of 103 patients with gastric MALT lymphoma for the period 2001–2013, were analyzed. The 103 median age of the patients was 53 years and the male to female ratio was 1:1. Serum lactate dehydrogenase and β2-microglobulin were within normal range. Macroscopically, the most commonly involved site was the antrum, followed by the corpus and fundus. A total of 97 patients (94%) tested positive for H. pylori. Forty patients (39%) had stage I, 35 patients (35%) had local or distant nodal involvement, 20 of 103 patients had stage IIIE (19%) and 8 of 103 patients had stage IV (7%) disease. Complete remission, after HPE, was achieved in 54 of the 69 patients (78%) that were H. pylori-positive and in 2 of the 4 patients (50%) that were H. pylori-negative. HPE had a superior trend in the H. pylori-positive patients although no significant difference was identified in the two groups (p=0.194). In patients with advanced disease, the 5-year progression-free survival (PFS) and overall survival (OS) estimates were significantly improoved for patients receiving HPE with CT or RT than those receiving CT or RT (p=0.046 and 0.035, respectively). The multivariate analysis revealed that, the advanced stages were independently associated with shorter PFS, and the modified-International Prognostic Index (m-IPI) (≥2) was associated with shorter OS. In conclusion, gastric MALT lymphoma had a favorable outcome with a high OS rate. HPE was an effective treatment for gastric MALT lymphoma. The patients with advanced stages and m-IPI (≥2) had a much worse prognosis.

Abstract
Though rare amongst stomach neoplasms, primary gastric diffuse large B cell lymphoma is one of the commonest extranodal non-Hodgkin lymphomas. If left untreated, it can have a devastating progression and life-threatening consequences. We present the case of a successfully treated large antral ulcer confirmed to be large B cell lymphoma as evidenced by radiologic, endoscopic and histopathologic findings. A brief discussion about the types of gastric lymphoma, their Helicobacter pylori relation and therapeutic modalities follows.

Abstract
BACKGROUND Primary gastric lymphomas (PGL) are rare and represent only 5% of gastric malignancies, but are apparently increasing in incidence worldwide. Optimal treatment of PGL remains controversial. The aim of this study was to evaluate clinicopathological characteristics, prognostic factors, survival rates, and treatment modalities in Tunisian patients with PGL. METHODS We retrospectively analyzed data from patients treated for PGL in our hospital over an 18-year period (1994-2011). RESULTS Data from 128 patients with PGL were retrospectively analyzed. Eighty-four were males and the median age was 57 years (range 5-89 years). The mean BMI was 22.9 (15-39). A total of 40 patients (31.2%) had a poor performance status (PS). The antrum was the most commonly involved site (52 cases, 40.6%). The most frequent pathological subtypes were diffuse large-cell lymphomas (46.4%) and mucosa-associated lymphoid tissues (32%). Disease was localized (stages IE and IIE) in 97 patients (75.8%). Ninety-six patients were evaluable. Chemotherapy alone was used in 73 (76%) patients, with 76.7% achieving complete remission. During chemotherapy, there were no severe complications requiring urgent surgery. Actuarial five-year overall and event-free survival were 60.2 and 54.3% respectively. We found no statistically significant difference in survival between patients treated with surgery and those treated by a conservative strategy. In the multivariate study, age greater than 60 years, poor PS, and BMI less than 20 were significant prognostic factors for overall survival (P=0.04, 0.009, and <0.001, respectively). CONCLUSION Surgery provides no advantage for survival over conservative treatment. Age, PS, and BMI were effective prognostic factors.

Abstract
Primary gastric diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease entity that includes patients with (DLBCL/MALT) and without detectable mucosa-associated lymphoid tissue (MALT) lymphoma components (de novo DLBCL). We sought to evaluate the clinical characteristics and outcome of this disease in a large number of cases. Patients with primary gastric DLBCL (n=162) seen on 2001-2011 at the Tianjin Medical University Cancer Institute and Hospital and the First affiliated Hospital of Chinese PLA General Hospital were retrospectively reviewed. The distribution of sex, age, Lugano staging, and other main clinical characteristics was similar between the de novo DLBCL and DLBCL/MALT groups (p>0.05). However, the proportion of patients with a stage-modified international prognostic index (m-IPI) ≥ 2 was higher in the de novo DLBCL (34 %) than the DLBCL/MALT group (17 %) (p=0.026). In addition, the Helicobacter pylori infection rates were higher in the DLBCL/MALT (75 %) than the de novo DLBCL group (36 %) (p<0.001). Five-year progression-free survival (PFS) and overall survival (OS) estimates were similar for patients in the de novo DLBCL (p=0.705) and DLBCL/MALT groups (p=0.846). Surgical treatment did not offer survival benefits when compared with chemotherapy for 5-year PFS (p=0.607) and OS estimates (p=0.554). There were no significant differences in 5-year PFS and OS estimates for patients treated with rituximab-chemotherapy (p=0.261) or conventional chemotherapy (p=0.227). Non-GCB subtype and m-IPI ≥ 2 were independently associated with shorter OS, and advanced stages of lymphoma were independently associated with shorter PFS.

Abstract
Objectives. The aim of this study was to evaluate clinical characteristics, prognostic factors, survival rates, and treatment modalities in patients with primary gastric lymphoma (PGL). Methods. We retrospectively reviewed and analyzed data from patients treated for PGL in our clinic from 1998 through 2010. Staging was performed using the Lugano Staging System. Overall and disease-free survival (OS and DFS) were calculated from the date of diagnosis. Results. We identified 79 patients. Thirty-seven patients (47%) were male. The median age at presentation was 57 (18–85) years. The median follow-up time was 41 (9–52) months. Thirty patients (38%) underwent surgery, 74 (92%) received chemotherapy, and 18 (23%) received radiotherapy. The five-year OS and DFS rates were 91.2% and 83.9%, respectively, in patients with stage I/II or IIE disease and 70.6% and 65.5%, respectively, in patients with stage IV disease (P = 0.02 for both rates). Treatment modality (surgical or conservative) had no impact on OS or DFS in early stages. In a multivariate analysis, poor performance status, advanced stage, and high LDH levels were significant bad prognostic factors for DFS, while advanced stage, poor performance status, and age > 60 years were significant bad prognostic factors for OS. Conclusion. Surgery provides no advantage for survival over conservative treatment; thus, conservative treatment modalities should be preferred initially at early stages of PGL.

Abstract
Background Optimal management and outcome of primary gastric lymphoma (PGL) have not been well defined in the rituximab era. This study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in Chinese patients with PGL. Methods The clinicopathological features of 83 Chinese patients with PGL were retrospectively reviewed. Staging was performed according to the Lugano staging system for gastrointestinal non-Hodgkin's lymphoma. Results The predominant pathologic subtype among Chinese patients with PGL in our study was diffuse large B cell lymphoma (DLBCL), followed by mucosa-associated lymphoid tissue (MALT) lymphoma. Among the 57 patients with gastric DLBCL, 20 patients (35.1%) were classified as the germinal center B cell-like (GCB) subtype and 37 patients (64.9%) as the non-GCB subtype. The 83 patients had a five-year overall survival (OS) and event-free survival (EFS) of 52% and 59%, respectively. Cox regression analysis showed that stage-modified international prognostic index (IPI) and performance status (PS) were independent predictors of survival. In the 67 B-cell lymphoma patients who received chemotherapy, 36 patients treated with rituximab (at least 3 cycles) had a mean OS of 72 months (95% CI 62-81) versus 62 months (95% CI 47-76) for patients without rituximab treatment (P = 0.021). Conclusion The proportion of Chinese gastric DLBCL cases with non-GCB subtype was higher than the GCB subtype. Stage-modified IPI and PS were effective prognostic factors in Chinese patients with PGL. Our data suggested that primary gastric B-cell lymphoma might have an improved outcome with rituximab in addition to chemotherapy. More studies are necessary, preferentially large prospective randomized clinical trials to obtain more information on the impact of the rituximab in the primary gastric B-cell lymphoma.
