Abstract
Simple Summary Gastric marginal zone lymphoma of the stomach is a rare cancer type primarily treated with oral proton pump inhibitors. If the disease does not respond to this, radiation is the treatment of choice. This review presents the development of radiation therapy over the last decades. Earlier, the stomach was surgically removed and irradiation was performed using large-field techniques and high doses of radiation. Currently, the standard treatment is the use of small-volume radiation therapy (with few side effects) with the preservation of the stomach, which provides excellent outcomes. In addition, this paper provides an outlook on current studies and possible future developments. Abstract Gastric marginal zone lymphoma (gMZL) of mucosa-associated lymphoid tissue (MALT) may persist even after H. pylori eradication, or it can be primarily Helicobacter pylori (H. pylori) independent. For patients without the successful eradication of lymphoma, or with progressive disease, treatment options have historically included partial or total gastrectomy. Presently, in these instances, curative radiation therapy (RT) is the current standard of care. This review emphasizes the historically changing role of radiation therapy in gMZL, progressing from large-volume RT without surgery, to localized RT, on its own, as a curative organ-preserving treatment. This overview shows the substantial progress in radiation therapy during the recent two to three decades, from high-dose, large-field techniques to low-dose, localized target volumes based on advanced imaging, three-dimensional treatment planning, and advanced treatment delivery techniques. RT has evolved from very large extended field techniques (EF) with prophylactic treatment of the whole abdomen and the supradiaphragmatic lymph nodes, applying doses between 30 and 50 Gy, to involved-field RT (IF), to the current internationally recommended involved site radiation therapy (ISRT) with a radiation dose of 24–30 Gy in gMZL. Stage-adapted RT is a highly effective and safe treatment with excellent overall survival rates and very rare acute or late treatment-related toxicities, as shown not only in retrospective studies, but also in large prospective multicenter studies, such as those conducted by the German Study Group on Gastrointestinal Lymphoma (DSGL). Further de-escalation of the radiation treatments with low-dose 20 Gy, as well as ultra-low-dose 4 Gy radiation therapy, is under investigation within ongoing prospective clinical trials of the International Lymphoma Radiation Oncology Group (ILROG) and of the German Lymphoma Alliance (GLA).

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
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
This study aimed to assess the efficacy of surgical treatment followed by post-surgical CHOP chemotherapy and to analyze the impact of T and N stage on survival in localized intestinal diffuse large B cell lymphoma (DLBL) patients. A prospective non-randomized study was conducted and 40 patients received primary surgical resection with lymph node dissection and post-operative CHOP chemotherapy. After a median follow-up duration of 33.3 months (range, 5.1-75.9 months), an estimated 5-year overall survival rate was 88.9% and a 5-year disease-free survival rate was 83.1%. Primary surgical resection followed by post-operative CHOP chemotherapy showed high efficacy in intestinal DLBL patients.

Abstract
BACKGROUND Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is associated with Helicobacter pylori infection, and regression of the tumor has been described after its eradication. OBJECTIVE To determine the value of EUS, in addition to other clinical/endoscopic features, in predicting the response of low-grade MALT lymphoma to H pylori eradication. DESIGN A retrospective, single-center study. SETTING AND PATIENTS Twenty-two patients with primary gastric MALT lymphoma were identified through a retrospective review of charts of patients seen at the American University of Beirut Medical Center. Only 19 patients with histopathologically confirmed gastric MALT lymphoma and H pylori infection who had EUS staging were included in the study. MAIN OUTCOME MEASUREMENTS Regression of the gastric MALT lymphoma as determined by follow-up endoscopy and mucosal biopsies. RESULTS Patients with disease restricted to the gastric mucosa had a significantly higher rate of complete remission after H pylori eradication compared with patients who had disease infiltrating into the gastric submucosa (77.8% vs 12.5%, P value .007). There was no statistical difference in terms of the mean follow-up time to achieve such response (P value .212). Age, sex, location of the tumor within the stomach, and endoscopic appearance did not correlate with the probability of complete remission of the MALT lymphoma. LIMITATIONS The limitations include a retrospective design and a relatively small sample population. CONCLUSION EUS determination of the invasion depth of gastric MALT lymphoma helps predict a complete response to H pylori eradication.

Abstract
Primary gastric lymphomas are the most common extranodal non-Hodgkin's lymphomas and are divided into indolent (low grade) and aggressive (high grade) types. They are mainly the disease of middle age, with a male predominance reported by most of the studies. For several years, surgery played a central role in diagnosis, staging, and treatment of this entity, yet recently there has been a move away from a surgical approach to conservative treatment. To determine the role of surgery as the initial treatment modality, we performed this retrospective single-center research on 245 patients with primary gastric lymphoma who were treated according to our protocol between 1990 and 2003. The patients' characteristics, distribution of histological types, treatment results, and disease-specific survival were followed. According to the histology, 59.2% had diffuse large B-cell lymphoma (DLCL), 26.1% MALT lymphoma, 9.8% mixed lymphoma (indolent and aggressive at the same time), while other types were infrequent. In total, 161 patients (65.7%) were treated with surgical resection as the initial treatment, which was then followed or not by additional therapy (chemotherapy, chemotherapy and radiotherapy, radiotherapy) depending on the histological type of lymphoma and the extent of residual disease after surgery. In 84 patients (34.3%), the treatment approach was conservative. The selection of treatment (chemotherapy, chemotherapy and radiotherapy, radiotherapy or Helicobacter pylori eradication only) was based on the histological type of lymphoma, considering also the patients' physical condition. The disease-specific survival in the group of patients who underwent surgery was statistically significantly better than in patients who were treated conservatively (p=0.049). At 5 years, it was 96.9% for the group treated with surgery and 89.8% in patients treated conservatively. However, the results were biased, as the patients who were treated conservatively were either in a worse performance status or presented with a more extensive disease. Similarly, in the DLCL type the disease-specific survival was better in the surgically treated group (97.2%) than in the conservatively treated patients (89.2%). The difference was barely significant (p=0.046) and again the results have to be considered with caution due to the selection of patients in a worse performance status or with a more extensive disease for conservative treatment. In the MALT lymphoma and mixed lymphoma types, there were no differences in the disease-specific survival between both treatment groups. Regarding the statement that for conservative treatment patients were selected who were unsuitable for the resection on account of concomitant diseases or due to the fact that the process was inoperable, we believe that the conservative approach gives comparable outcomes to the approach including initial surgery. The existing evidence thus no longer justifies surgery as the standard initial treatment and preference should be given to conservative treatment approaches.

Abstract
BACKGROUND Gastric non-Hodgkin's lymphoma (NHL) is a rare subtype of malignancy, for which no consensus exists about treatment. In this study, the treatment outcomes of gastric NHL in 57 patients were retrospectively evaluated for a period of 20 years at a single institute. METHODS Clinical stages were classified according to the Ann Arbor staging system: 29 patients were stage 1, 17 stage II, two stage III, and nine stage IV. The 46 stage I/II patients received aggressive, multimodal therapy: 24 of these (group A) were treated with surgery-based management, which included surgery alone (n = 6), surgery + chemotherapy (CT; n = 14), surgery + radiotherapy (RT; n = 2), and surgery + CT + RT (n = 2); 22 patients (group B) did not receive surgery, but received CT alone (n = 11), CT + RT (n = 5), or, in patients with low-grade mucosa-associated lymphoid tissue (MALT) lymphoma, an oral anti-Helicobacter pylori regimen (n = 6). The 11 stage III/IV patients received CT and/or RT with regimens similar to those for stage I/III patients. RESULTS Except for 1 patient with an initial surgical diagnosis, 56 patients underwent gastric endoscopic examination, which proved that 42 had NHL. The rate of diagnostic accuracy by gastroscopy was 75%. After multimodal treatment (n = 46) and a median follow-up of 54 months (range, 1-210 months), the 5-year survival rate was 40.3%. The 5-year survival rates for stage 1, II and III/IV patients were 57.2%, 47% and 0%, respectively (p < 0.005). Of the 24 surgical patients (group A) who received sequential CT, with or without RT, 12 remained disease-free after a median follow-up of 98 months (range, 1-210 months); three patients died because of postoperative complications. Of the 22 non-surgical patients (group B) who received CT, alone or combined with RT, 14 remained disease-free after a median follow-up of 40 months (range, 4-189 months); 1 patient died because of massive gastric hemorrhage after CT. All stage III and IV patients died after a median survival of 4 months (range, 1-8 months). CONCLUSION Clinical stage is the most important factor predicting the long-term survival of patients with gastric NHL. Surgery may still be necessary in cases of failed gastroscopic diagnosis. In early-stage gastric NHL, non-surgical treatment seems able to achieve the aims of improved long-term survival and, in some instances, cure.

Abstract
BACKGROUND & AIMS Appropriate management of primary gastric lymphoma is controversial. This prospective, multicenter study aimed to evaluate the accuracy of endoscopic biopsy diagnosis and clinical staging procedures and assess a treatment strategy based on Helicobacter pylori status and tumor stage and grade. METHODS Of 266 patients with primary gastric B-cell lymphoma, 236 with stages EI (n = 151) or EII (n = 85) were included in an intention-to-treat analysis. Patients with H. pylori-positive stage EI low-grade lymphoma underwent eradication therapy. Nonresponders and patients with stage EII low-grade lymphoma underwent gastric surgery. Depending on the residual tumor status and predefined risk factors, patients received either radiotherapy or no further treatment. Patients with high-grade lymphoma underwent surgery and chemotherapy at stages EI/EII, complemented by radiation in case of incomplete resection. RESULTS Endoscopic-bioptic typing and grading and clinical staging were accurate to 73% and 70%, respectively, based on the histopathology of resected specimens. The overall 2-year survival rates for low-grade lymphoma did not differ in the risk-adjusted treatment groups, ranging from 89% to 96%. In high-grade lymphoma, patients with complete resection or microscopic tumor residuals had significantly better survival rates (88% for EI and 83% for EII) than those with macroscopic tumor residues (53%; P < 0.001). CONCLUSIONS There is a considerable need for improvement in clinical diagnostic and staging procedures, especially with a view toward nonsurgical treatment. With the exception of eradication therapy in H. pylori-positive low-grade lymphoma of stage EI and the subgroup of locally advanced high-grade lymphoma, resection remains the treatment of choice. However, because there is an increasing trend toward stomach-conserving therapy, a randomized trial comparing cure of disease and quality of life with surgical and conservative treatment is needed.

Abstract
PURPOSE Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (MLS) is often associated with the presence of Helicobacter pylori (H. pylori) bacteria. Eradication of the infection with antibiotic therapy may result in regression of the lymphoma. But when antibiotic treatment fails to reverse the malignant process or if H. pylori is absent, other treatment options should be considered. Because MLS is often confined to the stomach and regional lymph nodes, it is potentially curable with local therapy. Endoscopy and improved imaging, with endoscopic ultrasound (EUS) and computerized tomography (CT), have reduced the prior dependence on surgery for diagnosis and staging of gastric lymphomas. METHODS AND RESULTS This review details the advances in the diagnosis, classification, and imaging of MLS. We also describe the experience that supports the use of radiation therapy as the preferred treatment of MLS in patients who have not responded to antibiotic therapy or have not had evidence for H. pylori infection. CONCLUSIONS Radiation therapy for MLS is not only effective and safe, but offers the significant advantage of low morbidity and gastric function preservation.

Abstract
BACKGROUND High- and low-grade gastric lymphomas (GL) differ in their behavior and chemosensitivity. Surgery has to be reevaluated according to the histologic grade of malignancy. We aimed to assess the place of surgery in the management of GL and its results after long-term follow-up. METHODS Among 54 patients with primary GL prospectively enrolled from 1984 to 1990, 45 with localized disease were studied. Primary resection was done whenever safe. All patients received chemotherapy adapted to the grade of malignancy and/or to the completeness of the resection. RESULTS Among 18 low- and 27 high-grade GL, 35 patients had primary resections; of those, 23 were complete. The complete response rate for all patients with low- and high-grade GL was 67% and 89%, respectively. After a median follow-up of 8 years, the disease-free survival rates for low-grade GL and high-grade GL were 94% and 89%, respectively. It was better after complete resection. CONCLUSION Complete resection is a major determinant of prolonged complete remission.

Abstract
BACKGROUND The definition of prognostic parameters in early stages of gastric lymphoma is still controversial. The aim of this retrospective analysis was to assess the value of the stage-modified international prognostic index (IPI) in predicting the outcome of a large, consecutive series of patients with PGL of diffuse large B-cell histology (DLCL). PATIENTS AND METHODS Three hundred twelve consecutive, newly-diagnosed, patients with localized PGL (stages I-IIE according to the 'Lugano staging system for GI lymphomas') referred from April 1972 to December 1997 to eight Italian and one Swiss centers were reviewed and their outcomes updated to June 1998. One hundred three patients were treated with single-modality therapy, while two hundred four received combined-modality treatment, most of which included surgery and short-term chemotherapy. RESULTS After a median follow-up of 66 months (range 0.6-300 months), 195 (64%) were alive in first continuous complete remission (CCR). The five-year estimates of overall survival (OS) and event-free survival (EFS) were 75% and 67%, respectively. OS and EFS varied according to IPI, from, respectively, 90% and 82% for patients with 0-1 risk factors, to 40% and 35% for patients with > or = 3 risk factors (P = 0.00001). Cox regression analysis showed that IPI was the strongest predictor of survival. CONCLUSIONS This study shows that stage-modified IPI is an effective predictive model in patients with primary DLCL of the stomach, enabling identification of patients with significantly different outcomes.

Abstract
Gastrointestinal lymphomas are almost exclusively of a non-Hodgkin's type. The Western form is characterized by a higher incidence of stomach location (50%), a MALT type (mucosa associated lymphoid tissue) (40%), a B-cell type (90%), and a high grade (55%). Chronic infection with Helicobacter pylori is an important risk factor. Mediterranean lymphomas form a particular clinical and pathological entity with diffuse involvement of the small bowel and are frequently being associated with a chronic malabsorption disorder. Eradication of Helicobacter pylori in early gastric lymphomas, and the use of tetracyclines in early Mediterranean lymphomas, have been shown to induce durable remissions. For more advanced gastric lymphomas, treatment usually consists of anthracyclin-based chemotherapy followed by involved field radiotherapy. Surgery is usually reserved for complications such as perforation or bleeding, or in some selected cases for salvage after failure of non-surgical therapy. For intestinal lymphomas, surgical resection whenever feasible, followed by anthracyclin-based chemotherapy is the most common treatment. Radiotherapy is usually reserved for consolidation in some clinical situations. The most commonly found prognostic factors are stage, grade, and tumor bulk. Treatment results vary with the presence of adverse prognostic factors and the used treatment combination. In general, patients with favorable disease receiving combined therapy have a 5-year relapse free survival (RFS) approaching 90%, whereas those with unfavorable disease have a RFS of 40-50%.

Abstract
BACKGROUND Although antibiotic therapy is emerging as effective initial treatment for patients with gastric lymphoma of mucosa-associated lymphoid tissue (MALT), there is a subset of patients for whom antibiotics are ineffective or inappropriate. Surgical resection can be curative, but total gastrectomy may be required for the eradication of all disease. To identify the optimal nonantibiotic therapy for early stage gastric MALT lymphoma, the authors retrospectively evaluated the Massachusetts General Hospital experience with gastric MALT lymphoma. METHODS Disease patterns and treatment outcomes were retrospectively analyzed in data from 21 consecutive patients with gastric MALT lymphoma who were treated between 1978 and 1995 at the Massachusetts General Hospital. RESULTS Sixteen patients were Stage IE, and 5 were in higher stages. Treatment consisted of resection with or without radiation or chemotherapy (14 patients), radiation alone (4 patients), or radiation plus chemotherapy (2 patients). Thirteen Stage IE patients received local therapy only. The 10-year actuarial relapse free survival rate for Stage IE patients was 93%, with 1 relapse among 15 treated patients. Because the patient who relapsed was treated successfully with chemotherapy, the 10-year cancer free survival was 100%. Overall survival for Stage IE patients was 93% at 5 years and 58% at 10 years, with no deaths from lymphoma. CONCLUSIONS These data indicate that a high probability of long term remission can be achieved with only local treatment of patients with Stage I gastric MALT lymphoma. Preliminary results suggest that radiation therapy is well tolerated and effective and may well be the optimal nonantibiotic treatment for patients with localized gastric MALT lymphoma.

Abstract
Histologic features of low-grade gastric lymphomas of mucosa-associated lymphoid tissue (MALT) have been extensively described, and transformation to a large cell (high-grade) lymphoma can occur. We characterize high-grade gastric lymphoma histologically in an attempt to distinguish between MALT-type and non-MALT-type lesions. We studied a series of 60 gastric lymphomas and characterized them clinically, histopathologically, and immunophenotypically. Low-grade gastric lymphomas were classified according to established criteria. High-grade lymphomas were classified in three groups based on the presence or absence of a low-grade component and lymphoepithelial lesions (LELs): 1) high-grade MALT lymphomas appearing in low-grade MALT lymphomas (LG/HG MALT lymphoma); 2) large cell lymphoma with LELs composed of large cells (high-grade LELs) but without a low-grade component (HG MALT lymphoma); and 3) diffuse large cell lymphoma without a low-grade MALT lymphoma component or LELs (DLCL). Twenty-two lymphomas were classified as low-grade MALT lymphomas, 16 as LG/HG MALT lymphomas, 10 as HG MALT lymphomas, and 12 as DLCL. B-cell immunophenotype was confirmed in all 55 cases in which immunophenotyping was performed. Low-grade LELs were seen in all low-grade MALT lymphomas, and CD20(L26) expression confirmed B-cell phenotype in the LELs in 20 of 20 cases. Clinical follow-up was available for 56 patients (range, 1-264 months; mean, 57 months). Actuarial analysis of disease-specific survival and relapse-free survival showed that clinical stage was highly statistically significant (P < 0.0001), whereas histologic type and grade approached statistical significance. Multivariate analysis showed that clinical stage was the only significant factor in relapse-free and disease-specific survival.

Abstract
The purpose of this paper is to report the clinical characteristics and treatment outcome following different therapeutic approaches in a large series of patients with primary low-grade MALT lymphoma of the stomach. A total of ninety-three patients (median age 63 years) were reviewed. The patients were treated by different modalities (local treatment alone, combined treatment, chemotherapy, antibiotics alone); seven patients refused any treatment. The antibiotic-treated group of patients was prospectively followed with regular endoscopic biopsies, and their responses were histologically evaluated. The 5-years projected overall survival is 82% (95% C.I.; 67%-91%) in the series as a whole. Second tumors were observed in 21.5% of the patients in this series (95% CI 14%v to 31%). There was no apparent difference in overall survival and event-free survival between patients who received different treatments. In the antibiotic-treated group histologic regression of MALT lymphoma was documented in 67% of patients (95% CI 51% to 80%). In conclusion the indolent nature of the disease justifies a conservative approach. The use of antibiotics as first-line therapy may avert or at least postpone the indication for surgical resection in the majority of patients.

Abstract
BACKGROUND: Gastric lymphoma is a common presentation of non-Hodgkin's lymphoma. Controversy reigns about many aspects of its classification and management, especially regarding roles for surgical resection. METHODS: The authors review the clinical features, staging, pathology, prognosis, and management issues with an emphasis on the role of surgical resection. RESULTS: Staging usually can be completed using noninvasive techniques. Those with a low-grade B-cell MALT type lymphoma with Helicobacter pylori infection may be treated with antibiotics and close follow-up. Patients with stage I or II disease may be treated with chemotherapy and radiation. Surgery is indicated for those with perforation or uncontrolled bleeding. CONCLUSIONS: Gastric lymphoma, primarily a B-cell tumor, can be diagnosed and managed effectively with various approaches. Few prospective, randomized trials of alternative approaches have been performed.

Abstract
BACKGROUND Surgery has been the mainstay of treatment for gastrointestinal (GI) lymphoma. The role of adjuvant chemotherapy to surgery has not been clearly elucidated. METHODS The review covered 100 patients who were diagnosed with primary GI lymphoma and treated from 1980 to 1993 at Providence Hospital (Southfield, MI), and Hartford and St. Francis Hospitals (Hartford, CT) with a median follow-up of 5 years. Forty-two patients were treated with surgery alone; 31 patients with surgery and adjuvant chemotherapy; 23 patients with primary chemotherapy, and 4 patients received no treatment. RESULTS The 5-year actuarial survival based on the above treatments calculated by life-table analysis were 57%, 76%, 58%, and 0%, respectively. This series showed that surgery with adjuvant chemotherapy significantly improved the 5-year actuarial survival of patients with primary GI Lymphoma and that primary chemotherapy showed comparable survival to surgery alone. There was no difference in prognosis when comparing patients with different stage, grade, or location of disease in the GI tract. CONCLUSIONS We recommend surgery when feasible with adjuvant chemotherapy as the mainstay of treatment for primary GI lymphoma. However, if a patient presents with comorbid factors, primary chemotherapy offers an effective alternative.

Abstract
Gut lymphoma still remains the subject of much debate and controversy with respect to pathological classification, clinical staging and treatment. This is mainly due to the fact that most studies reported retrospective non-randomized evaluations of small series and lacked uniformity in histological classification, patients' characteristics and type of treatment. Moreover, most of the historical series were published before the recognition of MALT as the origin of most GI lymphomas. Hence, there is a compelling need for the use of modern histological criteria for primary GI lymphomas because of their unique histology, special features and origin in mucosal tissue. General adoption of the histological classification proposed in 1988 by Isaacson et al (Table 1) can be recommended which follows the general principles of the Kiel Classification and includes the MALT lymphomas as a particular disease entity. Combination chemotherapy is the treatment of choice for gut lymphomas with aggressive histology and multiple node involvement or disseminated disease. The effectiveness of combination chemotherapy in advanced disease has excited a reconsideration of the role of primary surgery in less advanced cases where surgery has, historically, been the initial procedure of choice. This is particularly true for gastric lymphomas where it is possible that, in future, surgery will be resorted to as a potential approach for salvage when complete remission is not achieved with conservative therapy. For primary intestinal lymphoma, however, there are as yet no studies which clearly demonstrate that surgery is not necessary. With respect to the group of localized low-grade MALT lymphomas of the stomach and the indolent nature of the disease make plausible a conservative approach, with antibiotic eradication of H. pylori as the sole initial treatment. This may avert or at least postpone the indication for surgical resection in the majority of patients.

Abstract
BACKGROUND Non-Hodgkin's lymphoma (NHL) remains a rare form of gastric malignancy, with a rising incidence. Approaches to treatment vary from surgery alone to conservative management. METHODS To determine the optimal scheme of treatment, a randomized clinical trial was undertaken. Seventy-five patients were randomized into three groups: A-surgery alone (25), B-surgery followed by chemotherapy (29), and C-radiation therapy followed by surgery and chemotherapy (21). Forty-nine patients had stage IE and 26 had stage IIE disease. Chemotherapy (COP and COPP) consisted of 6 courses during a 1-year period, with the courses being 6 weeks apart. RESULTS Subtotal gastrectomy was performed in 26 patients. Forty-nine patients underwent total gastrectomy. Postoperative complications occurred in 6 (8%) patients: 3 (12%) in group A, 2 (6.9%) in group B, and 1 (4.7%) in group C. Postoperative mortality occurred in 2 (8%) patients in group A (2.7% of all patients). An increase in hospital admissions number per year and decrease of mean age of patients with NHL of the stomach after the Chernobyl accident on April 26, 1986 was noted. CONCLUSIONS Improved survival in gastric NHL was achieved by a combination of preoperative radiation with surgery and postoperative chemotherapy, presumptively through the management of local and systemic disease.

Abstract
Lymphoid neoplasia is a complex area comprising multiple diseases with varied pathology, treatment, and outcome. The non-Hodgkin's lymphomas are reviewed here. Non-Hodgkin's lymphomas, collectively, represent the sixth most common cancer in the United States as well as the sixth most common cause of cancer deaths. The overall incidence of non-Hodgkin's lymphoma has risen steadily over the past four decades. Although some of this is attributable to human immunodeficiency virus (HIV)-associated lymphoma, HIV-associated disease accounts for only a small part of the increase in lymphoma. As our knowledge of normal as well as neoplastic lymphoid development has expanded on the basis of histopathology as well as adjunct cellular and molecular techniques, multiple classifications have been proposed to take these into account. The clinical relevance to our understanding of non-Hodgkin's lymphoma is the concept that various lymphoid cancers are counterparts of stages of normal lymphoid development. Stages of lymphoid development in terms of cell surface markers and immunoglobulin gene rearrangements have been well characterized. These are particularly applicable to the early B-cell development, which is antigen-independent and occurs in the bone marrow. Diseases correlating with these stages are largely acute lymphocytic and lymphoblastic leukemia/lymphoma and high-grade lymphomas, such as Burkitt's lymphomas. Much has been learned recently about subsequent antigen-dependent B-cell development in secondary lymphoid organs to improve our understanding of the corresponding stages of B-cell neoplasia. Many of these stages correlate with more recently described entities such as mantle cell and marginal zone lymphomas. Histologic study remains crucial in determining the subtype of NHLs, whereas immunohistochemistry, surface phenotype, and molecular studies are useful in selected cases. Although some lymphoma classifications may be better in terms of understanding the lymphoma biology, the working formulation remains useful to guide clinical decision making. Lymphomas classified as low grade are considered incurable with standard therapy when diagnosed, as is usual, at advanced stages. Different subtypes may have different median survivals, but the goal has typically been palliation, whereas experimental approaches are clearly needed. Intermediate and high-grade lymphomas are potentially curable with aggressive combination chemotherapy. Recent evidence suggests that CHOP chemotherapy is as effective as more complex regimens. Still, 40% to 50% of patients are cured. Prognostic factor analysis has allowed separation of subgroups with much better survival in whom CHOP is adequate versus those with much poorer survival in whom experimental approaches are rational. Additional subtypes of lymphomas have been described and characterized since the working formulation was developed, including mucosa-associated lymphoid tissue tumors (MALT-oma), mantle zone lymphoma, anaplastic large cell lymphoma and AILD-like T-cell lymphoma. Approaches to these entities are still being optimized. Newer approaches, including high-dose therapy with stem cell support, biologic agents, and newer chemotherapeutic agents are discussed, as are special situations such as localized lymphoma of certain sites and lymphoma in immunosuppressed patients.

Abstract
Eighty-two patients with primary gastric (IE, II1E, and II2E) non-Hodgkin's lymphoma according to the Musshoff's staging system were treated with combined modality including surgery with/without radiotherapy between January 1985 and December 1991. According to the Updated Kiel classification 54 had high-grade histologic subtypes and 28 low-grade. The strategy throughout the study was to resect primary tumor: all patients underwent gastrectomy, 40 subtotal and 42 total gastrectomy. The resection permitted complete surgical staging utilizing three pathologic features: disease confined within or beyond the serosa, negative/positive regional lymph nodes, and negative/positive surgical margins. If there was no evidence of these pathologic factors, the patients who underwent surgery alone received no further radiotherapy. On the other hand, all patients who presented at least one of three pathologic factors were treated with adjuvant radiotherapy after the resection. All except 14 patients presented at least one of the pathologic features and 50 (61%) patients had involvement of the whole gastric wall. Radiotherapy included the gastric bed and para-aortic lymph nodes and, for the patients, who had positive regional lymph nodes in combination with the complete involvement of the gastric wall, the irradiation included the whole abdominal approach. The complete response rate was 97% and the 9-year disease-free survival was 93%. All but one of the 5 relapses occurred within 18 months stressing the need for more specific staging. Gastric resection with/without radiotherapy may still represent the primary therapeutic procedure in early stage gastric non-Hodgkin's lymphoma.

Abstract
A retrospective study was conducted of 49 patients with primary gastrointestinal lymphoma to analyze clinicopathological features, prognostic factors, and results of treatment. Intestinal lymphomas (63%) were more common than gastric lymphomas (29%). Endoscopic biopsy was diagnostic in 64% of gastric lymphomas, while 97% of intestinal lymphomas required laparotomy for diagnosis. Lymphoblastic (35%) and diffuse large cell (33%) lymphomas were the most frequent histologic types. Complete remission (CR) was achieved in 61% of patients, with a 5-year survival of 72% in those who achieved CR. The overall 5-year survival and disease-free survival were 47% and 40%, respectively. All disease-related mortality occurred within 2 years of diagnosis, with 79% occurring in the first year. There was no overall significant difference in survival between the different treatment groups. Stage, extent of surgical resection, response to treatment, serosal involvement, multimodality treatment, and performance status were significant prognostic factors. Achievement of complete remission and complete surgical resection were the most favorable independent prognostic factors on multivariate analyses.

Abstract
The treatment of early-stage gastric lymphoma is controversial. This retrospective analysis reports on the outcome of 24 patients treated in our institution during the past 25 years. Fourteen patients had stage IEA, one patient had IEB, six patients IIEA1, and three patients had stage IIEA2 non-Hodgkin's lymphoma (NHL). Diffuse large cell intermediate-grade NHL was diagnosed in 17 patients, diffuse small cleaved cell in three patients, and diffuse mixed large and small cell lymphosarcoma, low-grade B-cell lymphoma, and unclassified lymphoma in one patient each. Fourteen patients underwent surgery, 21 had radiation therapy (XRT), and 10 patients received chemotherapy. Surgery + XRT were given to 7 patients, surgery + XRT + chemo and XRT alone were delivered to five patients each, and XRT + chemotherapy were employed in four patients. Surgery alone was the initial treatment in two patients and chemotherapy alone was given to one patient. Following treatment 22/24 achieved a complete response. During a mean follow-up period of 77.6 months (range 1-285), five patients relapsed. At 10 years, the actuarial survival of the 15 patients with stage I disease was 57.4% and for stage II it was 51.9% (Gehan P-value 0.33). Freedom from relapse (FFR) was 60.7% and 58.3%, respectively (P-value 0.56). No significant statistical differences in terms of survival and FFR were noted in patients treated with surgery, chemotherapy, or XRT. The outcome of patients treated with triple-modality therapy was similar to those treated with double-modality therapy and to patients treated with XRT alone. Gender, age, presenting symptoms, depth of tumor through the gastric wall, and stage were not statistically significant for prediction of either survival or FFR. Both surgery + XRT and chemotherapy + XRT are effective in the treatment of early-stage gastric disease. XRT alone is equally effective as two or three modality treatments in the subset of patients with early-stage gastric lymphoma. However, the low number of patients treated with various approaches over a long period precludes a firm conclusion. Until prospective randomized studies are initiated, management programs should be individually tailored.

Abstract
Background Clinical approaches to early primary gastric non-Hodgkin's lymphomas have not yet been clearly defined, and the role of postoperative radiotherapy remains a matter of discussion. Methods Twenty-seven patients with early primary gastric non-Hodgkin's lymphoma were observed from December 1978 to December 1990 at our Institution. They were staged according to Musshoff and Schmidt-Volmer (19) as I E (n = 16), II E 1 (n = 7) and II E 2 (n = 4). All of them underwent local combined treatment, consisting of surgery and postoperative radiotherapy; chemotherapy was also administered to 10 patients, mainly with the CHOP regimen, for 4-6 cycles before radiotherapy. Irradiation was delivered using 10 MV photons from a linear accelerator. Large abdominal fields were employed in 21 cases with daily fractions of 1.5-2 Gy up to a median total dose of 30 Gy (range: 27-36 Gy). Six patients were irradiated only on the surgical bed up to 40.5 Gy (range: 39-40.5 Gy). Results The 5-year overall and disease-free survivals were respectively 92.4% and 89.8%. The main known prognostic indicators, stage of disease, type of surgery as well as age and sex, were not found to be statistically significant in our series. No clear difference emerged between patients sequentially treated with the combination surgery-chemotherapy-radiotherapy and those who did not receive adjuvant chemotherapy. Two patients recurred at distant sites, but no local failure was seen during the follow-up. Conclusions Although no firm conclusion can be drawn, our experience, in agreement with recent published reports, points out that the use of postoperative radiotherapy is associated not only to favorable results in terms of local control and survival, but also, and moreover, to a negligible incidence of side effects and sequelae. However, in the absence of multi-institutional prospective randomized studies, whose activation is nowadays strongly warranted, the exact role of adjuvant therapies remains a matter of discussion, and the optimal treatment of early primary gastric non-Hodgkin's lymphoma still depends on individual experience and the physician's philosophy.

Abstract
Sixty-six consecutive patients with primary gastric non-Hodgkin's lymphoma are reported. All patients underwent surgery which consisted of radical resection in 23 patients (36%) and partial or palliative excision in the remaining 43 cases (36 and 7 respectively). Three patients died before starting chemotherapy, two refused the treatment and 61 completed the postoperative chemotherapeutic programme. We analysed this group of patients in order to assess the efficacy of chemotherapy following surgery. Chemotherapy included either CVP or the original protocols from our institution. Excluding patients who underwent radical resection, postoperative chemotherapy induced complete remission in 87% of the remaining 39 patients. After a median follow-up of 84 months (range 6-216), the 10-year cause-specific survival was 90% with a stable curve plateau after about 25 months. The survival was only influenced by response to therapy (p < 0.0001). The disease-free survival for patients who were not radically resected was 93%. We encountered only two relapses after 15 and 32 months. One of these was local and the other systemic. Our results indicate that chemotherapy following surgery induces long-term remission and survival in primary gastric lymphoma and in particular improves remission and survival, in stage II. In our opinion, surgery may also be fundamental for the treatment of gastric lymphoma in the majority of cases.

Abstract
BACKGROUND Although primary gastric lymphoma is the most common extranodal lymphoma, no specific staging system exists. METHODS The authors reviewed 98 cases histologically classified according to the Working Formulation, including low grade B-cell lymphoma of mucosa-associated lymphoid tissue type. Survival rates were calculated by the Kaplan-Meier method according to T, N, and M of the general rules of the International Union Against Cancer TNM system. The definitions of these categories are as follows: T1, tumor invades the lamina propria or submucosa; T2, the muscularis propria; T3, the subserosa; T4, the serosa without invasion of adjacent structures; T5, adjacent structures; N0, no regional lymph node metastasis; N1, perigastric lymph nodes within 3 cm of the edge of the primary tumor; N2, perigastric lymph nodes more than 3 cm from the edge of the primary tumor or in lymph nodes along the left gastric, common hepatic, splenic, or celiac arteries; N3, paraaortic and hepatoduodenal lymph nodes and/or other intraabdominal lymph nodes; N4, beyond N3; M0, no distant metastasis; and M1, positive. RESULTS The overall 5-year survival rate was 83.5%; it was 100% in T1, 82.4% in T2, 84.2% in T3, 52.9% in T4, and 33.3% in T5; 93.9% in N0, 90.5% in N1, 66.2% in N2, and 44.4% in N3/N4; and 86.0% in M0 and 25.0% in M1. Based on these results, the authors proposed a new staging system as follows: Stage I, T1/N0, N1/M0; Stage II, T1/N2/M0, T2,T3/N0,N1,N2/M0; Stage III, T4,T5/any N/M0, any T/N3, N4/M0; and Stage IV, any T/any N/M1. According to this system, the 5-year survival rate significantly decreased as the stage progressed: 100% in Stage I, 88.9% in Stage II, 52.1% in Stage III, and 25.0% in Stage IV. In Stages I and II, survival rates were not significantly different whether chemotherapy was done or not, whereas in Stage III all patients treated with surgery alone died. CONCLUSIONS This staging system is useful for assessing prognosis of and deciding a therapeutic plan for primary gastric lymphoma.

Abstract
BACKGROUND/AIMS Gastrointestinal lymphoma is a rare disease. A study was conducted to assess its prevalence and clinical features in adult patients with lymphoma. METHODS Retrospective analysis of 1352 patients with adult non-Hodgkin's lymphoma showed 300 (22%) cases with gastrointestinal involvement at initial presentation. RESULTS Of the 185 patients with primary gastrointestinal lymphoma, 94 (51%) had gastric primary lymphoma and the rest (49%) had a lymphoma of intestinal origin. Patients with intestinal lymphoma were considerably younger (median age, 35.0 years), frequently had multifocal disease (14%), and had a 10-year survival rate of 48%. Cases with gastric primary lymphoma had a median age of 54.5 years (P < 0.001) and rarely had multifocal disease (1%; P < 0.001) but had an equal 10-year survival rate of 53% (P = 0.431). For both groups, the combined surgical resection followed by chemotherapy led to better 10-year survival (45%) compared with either modality used alone (0% and 35%, respectively; P < 0.05). Better survival was also noted in ambulatory patients, younger patients, those with localized disease, and those without intestinal perforation. Another 115 patients had gastrointestinal involvement secondary to disseminated disease with frequent high-grade histology (29%) and a poor 10-year survival rate of 22%. CONCLUSIONS Gastrointestinal involvement is relatively common in patients with adult lymphoma. Multimodality treatment appeared superior to therapy with either surgery or chemotherapy used alone.

Abstract
Prognostic factors and treatment results were analysed in 28 consecutive patients with primary gastric lymphoma (PGL) diagnosed and treated, all by surgery and in many cases with additional chemotherapy (CT) and/or radiotherapy (RT), between 1977 and 1988. There were 13 patients in stage IE, 5 in IIE, and 10 in stage IV. The resection rate was 96.4% (27/28). Sixteen patients underwent an extended total and 11 a subtotal gastrectomy. Seventeen out of 25 cases (68%) were diagnosed by endoscopic biopsies. In 10 endoscopically diagnosed PGL cases the clinical staging and separation between stages IE and IIE from stage IV, due to ultrasonographic scan, computed tomography and bone marrow biopsy, was correct and the same with the surgical-pathological staging information. According to the Kiel-classification 18 patients had a low-grade and 9 patients a high-grade lymphoma. One patient could not be classified. All patients were completely followed-up, in an average time of 52 months. The probability of overall 5-year survival was 92% in stage IE, 75% in stage IIE, 88% in stages IE+IIE together, and 35% in stage IV. Extent of surgery (total vs. subtotal gastrectomy), Kiel-classification (low-grade vs. high-grade malignant histologic subtypes) and adjuvant CT in patients with stage IE (all 11 patients without CT remain in complete remission after an average of 45 months) did not significantly influence survival. The sole prognostic factor with proven impact on survival was the stage of disease (IE+IIE vs. IV: P = 0.001). For the Kiel-classification in particular there was no significant difference between low-grade and high-grade lymphomas with regard to the sex, symptomatic, extent of surgery, and stage at operation. These findings, together with data from the literature, suggest that gastric resection seems to be the optimal primary treatment in clinically assessed stages IE or IIE. In patients with stage IE disease, surgical resection can result in a cure, with no need for further therapy. The CT and/or RT can be effective in unresected and even bulky cases. Because of the difference in primary treatment, a preoperative clinical staging and separation between early stages from stage IV is always indicated.

Abstract
BACKGROUND The CD30/Ki-1 antigen characterizes a series of non-Hodgkin's lymphomas (NHL) predominantly showing anaplastic large cell (ALCL) morphology and frequently involving the skin and other extranodal sites. In cutaneous large cell lymphomas, the CD30 expression was indicated as a favorable prognostic marker independently from cytology, anaplastic versus nonanaplastic. The stomach is the most common site of extranodal lymphomas in the adult population, but primary gastric CD30+ lymphomas have been reported rarely. METHODS The clinical, morphologic, and immunohistochemical features of six cases with primary CD30/Ki-1+ gastric large cell lymphomas were analyzed. RESULTS The mean age of patients was 64 years with a prevalence of women (M:F ration = 1:2). Patients were assigned to Stage IE or IIE. Three of them died of disease, whereas the others are still alive (mean follow-up, 18 months). Three of six cases had ALCL morphology, whereas other cases had centroblastic, immunoblastic, and high-grade mucosa-associated lymphoid tissue lymphoma. Immunohistochemistry revealed a B-cell phenotype in three of six cases; a T-cell phenotype in one of six cases; and a null, non-B, non-T phenotype in two of six cases. CONCLUSIONS Within CD30+ primary gastric large cell lymphomas, cytology, anaplastic versus nonanaplastic, did not affect clinical presentation and/or prognosis. The survival rate of the patients studied is in keeping with literature reports regarding prognosis of primary high-grade gastric NHL. The findings suggest that clinical behavior of this extranodal lymphoma is more closely related to clinical symptoms and initial stage of disease than to CD30 expression.

Abstract
We describe 53 patients with primary gastric non-Hodgkin's lymphoma (38 stage IE,15 stage IIE) treated with surgery as a primary procedure. According to the Working Formulation, 13 cases had low, 21 had intermediate and 19 had high grade malignancy. 34 patients considered at high risk received postoperative polychemotherapy. The overall 10-year disease-related survival is 91%. Median follow-up is 52 months. 7 patients relapsed (13%). The 10-year disease-free survival rate of the 19 patients initially treated with surgery is 60%, as compared with 92% in the patients who also received chemotherapy (P = 0.004). However, overall survival did not differ between the two groups, since two-thirds of the patients who relapsed after surgery alone were rescued with chemotherapy. Stage, age, sex and histology did not correlate with survival. In our experience, surgery was an adequate first step procedure; the addition of chemotherapy significantly reduced relapses and increased the disease-free survival rate in patients with unfavourable prognostic factors.

Abstract
BACKGROUND The optimal management of primary gastrointestinal lymphoma including the use of surgery remains unsettled. This prospective study aimed to determine the prognostic factors of primary gastrointestinal lymphoma and to evaluate a therapeutic strategy based on surgical tumor reduction, followed by chemotherapy adapted to the histological type of tumor and tumor removal or nonremoval. METHODS Ninety-one patients were included (mean age, 50.4 years) with mainly gastric (61%) or several digestive tract organ (18%) involved sites in clinical stages IE (43%), IIE (27%), and IV (30%). Three therapeutic groups were defined: group I, patients with low-grade lymphoma (n = 28); group II, patients with high-grade lymphoma who had complete tumor removal (n = 24); and group III, patients with high-grade lymphoma who had only partial or no tumor removal (n = 39). Each group underwent adapted chemotherapy. RESULTS The respective overall 5-year survival rates for groups I, II, and III were 81% +/- 6%, 100%, and 56% +/- 8%, respectively (P < 0.0001). By Cox multivariate analysis, the prognostic factors of survival were age under 65 (P < 0.05), gastric localization (P < 0.05), stage IE (P < 0.001), and radical or incomplete surgery (P < 0.01). CONCLUSIONS Combined radical surgery and chemotherapy according to histological grading is associated with prolonged remission in patients with primary digestive tract lymphoma. Moreover, compared with chemotherapy alone, incomplete resection of tumor is associated with increased survival of high-grade lymphomas.

Abstract
The records of 30 patients with primary gastric lymphoma and a minimum of 5 years of follow-up were reviewed and clinical and pathologic prognostic factors analyzed. The overall 5-year survival was 40% (median 23 months). No significant relationship between surgical and patient age, sex, duration of symptoms, macroscopic appearance, or size of the primary lesion or degree of serosal infiltration was demonstrated. Stage of disease and site of primary had an impact on prognosis. Survival was improved in patients with stage I-II disease (P < 0.05) and in patients with primary located in the distal third of the stomach (P < 0.05). Although histology in all three classifications did not correlate well with survival, patients with low-grade lymphoma according to Kiel showed improved outcome (P < 0.05). Five-year survival of 11 patients with positive lymph nodes, 6 of whom were treated with cytotoxic therapy, was 54% and comparable to that of 7 patients (56%) with no nodal involvement who did not receive chemotherapy after surgery.

Abstract
PURPOSE To identify prognostic factors in localized gastric lymphoma patients for optimal therapy selection. METHODS AND MATERIALS From 1974 to 1990, 77 patients with localized gastric lymphoma (38 Stage IE and 39 Stage IIE) were treated with radiation therapy, chemotherapy, surgery, or a combination. Univariate and multivariate local control and survival analyses were performed on possible prognostic factors, such as patient age, gender, histologic subtype, stage, tumor size, depth of penetration, multicentricity, and treatment modality. RESULTS At 5 years, the relapse-free survival was 52%; 74% of the relapses occurred at local sites. Smaller tumor size was most strongly associated with local control (p = .001) and relapse-free survival (p < .001). Patients with tumor sizes < or = 5 cm had relapse-free survival of 87%, compared with 41% and 15% for those with tumor sizes of 5.1 cm to 10 cm and > 10 cm, respectively. The 47 patients who received combined-modality therapy had a relapse-free survival of 65%, compared with 24% for the 30 who received single-modality therapy (p < .01). Although patient age, stage, depth of penetration, and resective surgery affected the above endpoints, these factors were not independent predictors of outcome. Analysis of treatment subgroups showed that surgical resection combined with postoperative irradiation was associated with highest local control (p = .002) and the best relapse-free survival (p = .004), when compared with other treatment modalities. In 27 patients with tumor sizes < or = 5 cm, comparison of the 15 patients who had surgery with the 12 who did not failed to reveal a local control benefit from the addition of surgery. CONCLUSION These data demonstrate that tumor bulk is an important prognostic determinant of local control and relapse-free survival in localized gastric lymphoma patients. Stage IE and IIE lymphoma of the stomach can be selectively treated with primary radiation, but surgical resection may be necessary for large tumors (> 5 cm), followed by adjuvant radiation.

Abstract
The literature after 1980 dealing with the treatment of primary gastric non-Hodgkin's lymphoma (stages I and II) is reviewed. Gastrectomy is recommended for patients with acute symptoms at presentation or with complications of chemotherapy or radiotherapy. In elective cases, patients with stage I disease may be candidates for gastrectomy as a single therapy, provided that tumour-free resection margins are achieved. There is no evidence of substantial benefit from adding postoperative chemotherapy or radiotherapy after an apparently radical resection. In stage II disease, the best results are achieved with ablative surgery plus adjuvant therapy. The resection volume should be limited to macroscopically involved structures, in principle avoiding total gastrectomy and extensive lymph node dissection, since residual disease may be optimally controlled with radiotherapy or chemotherapy. Primary chemotherapy, with or without radiotherapy, represents an experimental approach; the advantages of sparing the stomach must be balanced against the toxicity of an aggressive chemotherapy regimen and the risk of emergency operation for iatrogenic complications.

Abstract
We performed a retrospective study involving 56 patients with stage IE or stage IIE gastric lymphomas treated between January 1980 and January 1990. Endoscopy had a sensitivity of 98% compared with 83% for radiographic contrast studies. The data were analyzed with respect to 10 prognostic factors. Age greater than 65 years and an elevated lactate dehydrogenase level were associated with a significantly lower 5-year survival rate (each p = 0.001). Those patients having had gastric resection with grossly negative margins demonstrated improved survival compared with those patients who did not have complete resection (67% versus 29%). The use or omission of radiotherapy had no effect on survivorship (51% versus 55%). Neither tumor size, stage, sex, site of extragastric involvement, time from onset of symptoms to diagnosis, nor microscopic resection margins influenced survival. We conclude that endoscopy with biopsy is the diagnostic procedure of choice for gastric lymphoma. Gastric resection still plays an important role in the management of stage IE and stage IIE gastric lymphomas, whereas chemotherapy remains the mainstay of therapy. The role of radiotherapy remains undefined.

Abstract
Three hundred seven cases (244 gastric, 63 intestinal) of primary gastrointestinal non-Hodgkin's lymphoma (NHL) in stages EI and EII, according to a modified Ann Arbor system, were examined retrospectively. The histological classification for mucosa-associated lymphoid tissue-derived lymphomas was applied. Gastric NHLs (male-female ratio, 0.97; mean age, 64.5 years) were stage EI in 51% and stage EII in 49% of cases. Histological grade of malignancy was low in 41% and high in 59% of cases; all NHLs were B-cell type. Tumors were radically resected in 87%, and overall 2-, 5-, and 10-year survival rates were 61%, 55%, and 46%, respectively. Early lymphomas (substage EI1) had best prognosis (5- and 10-year survival rates, 90% and 70%, respectively). Intestinal NHLs (male-female ratio, 1.1; mean age, 54.4 years) were stage EI in 30% and stage EII in 70% of cases. Histology was low grade in 21% and high grade in 79%, and all but 11 cases were B-cell type. In 58% of cases, radical tumor resection resulted in overall 2- and 5-year survival rates of 44% and 24%, respectively. Major prognosticators for survival in gastric location were low-grade histology, low depth of infiltration, and low stage and radical resectability of lymphoma; all factors were strictly intercorrelated. In intestinal site, radical tumor resectability was highly significant for survival. Cumulative proportion of relapses after 5 years was higher in intestinal than in gastric sites (44% vs. 22%). In conclusion, primary gastrointestinal tract NHLs may represent an entity with respect to characteristic histological features, focal tumor growth, and potential cure by radical resection. Because of late relapses, clinical follow-up is needed.

Abstract
Prognostic factors and treatment results were analysed in 72 consecutive patients with primary gastric lymphoma treated between 1970 and 1985. There were 37 patients in stage IE, 17 in IIE, 3 in IIES and 15 in stage IV. Histopathological re-evaluation and classification according to the TNM system were performed. We found that disseminated disease (stage IV), serosal penetration (T3), involvement of adjacent organs (T4) and extensive abdominal lymph node involvement (N3) were poor prognostic factors. Neither histological malignancy grading, nor the appearance of lympho-epithelial lesions were significantly associated with relapse-free survival. Forty-six patients with 'limited localized' disease (stage IE, IIE, N3 excluded) received potentially curative treatment (surgery, radiotherapy, chemotherapy or combinations thereof), of whom 85% remained relapse-free. Thirty-four patients did only get local treatment (surgery and/or radiotherapy) with curative potential, the relapse-free survival rate was 85%. We conclude that primary gastric lymphoma stage IE and IIE (N3 excluded) is often a truly localized disease that can be cured with local therapy.

Abstract
Resection specimens from 145 patients with primary B-cell gastric lymphoma at stage IE (n = 88) and at stage IIE (n = 57) were investigated. Histologically, low-grade malignant B-cell lymphomas arising from the mucosa-associated lymphoid tissue, including immunocytoma (n = 71), could be distinguished from high-grade malignant B-cell lymphomas with (n = 25) and without (n = 49) evidence of a low-grade component. The very rare low-grade B-cell lymphomas of centroblastic-centrocytic, centrocytic, and plasmacytic type were not considered. All patients had undergone primary gastric resection, and 65 received additional chemotherapy (n = 33), radiotherapy (n = 22), or both (n = 10). Actuarial overall survival rates calculated by the Kaplan-Meier life-table method were 76% after 5 years and 58% after 10 years. According to the Mantel test and a multivariate analysis using the Cox regression method, patients at stage IE had a significantly better survival probability than those at stage IIE (P less than 0.0001); 5-year survival rates were 87% and 61%, respectively. The survival probability for low-grade malignant lymphomas was significantly better than for tumors with secondary high-grade transformation (P less than 0.05) or for primary high-grade lymphomas (P less than 0.0001), whereas the two high-grade groups were not significantly different. Five-year survival rates were 91% for low-grade, 73% for secondary high-grade, and 56% for primary high-grade malignant lymphomas. Retrospectively, no significantly different survival rates were found between patients who had undergone gastric resection alone and patients who had received additional treatment. However, survival analyses showed that classification and grading according to the histopathological concept of mucosa-associated lymphoid tissue-derived gastric lymphomas into low-grade B-cell lymphomas of mucosa-associated lymphoid tissue type and high-grade B-cell lymphomas with or without evidence of a low-grade component has great prognostic relevance.

Abstract
Between 1973 and 1989, 49 patients with gastrointestinal lymphomas were treated at the Virginia Mason Medical Center, Seattle, Washington, and followed in the tumor registry. The purpose of this review was to determine the influence of treatment on long-term survival of these patients. The mean age was 63 years (range: 38 to 83 years). There were 33 men and 16 women. The primary tumor sites were gastric 33 (67%), small bowel 11 (22%), and colon 5 (10%). Common signs and/or symptoms at presentation were pain (n = 38), bleeding (n = 11), and weight loss (n = 14). The diagnostic sensitivities of contrast radiography, computed tomography, and endoscopic biopsy were 76%, 89%, and 79%, respectively. Forty-eight patients were treated, and one received supportive care only. Thirty-one patients had surgical resections, 33 patients had chemotherapy, and 16 patients had radiotherapy. Most (n = 30) had multimodality treatment. Statistically significant variables affecting survival rates in patients with gastric lymphomas were lower tumor stage, younger patient age, and surgical resection.

Abstract
Forty-three endoscopic biopsies from 29 patients with confirmed gastric lymphoma (GL) were analyzed retrospectively to establish the morphologic criteria of greatest diagnostic significance. An average of 10 tissue samples was obtained at each endoscopy. In 44% of the cases, lymphoma was discovered in only one or two of the tissue portions. Eighteen lymphomas were primary, six were probably primary, and five were generalized. The diagnosis of lymphoma was originally suspected or established in 46% of the biopsies. However, a review of the histologic sections indicated that the changes, either diagnostic of or compatible with lymphoma, were present in 75% and 18% of the sections, respectively. Most diagnostic errors consisted of confusion with diffuse lymphoid infiltrates in chronic gastritis and/or peptic ulcer, and less frequently with poorly differentiated carcinoma. In those cases confused with chronic gastritis or peptic ulcer, biopsies showed centrocyte-like cells of the standard type or small lymphocytes which produced: (1) a marked increase in density of the lymphoid infiltrate in the gastric mucosa, (2) massive substitution of gastric glands by lymphoid infiltration, and (3) a collection of lymphocytes infiltrating and partially destroying isolated glands (lymphoepithelial lesion). From 48 biopsies having intense benign lymphoid infiltrates, three were interpreted (by means of a blinded study) as compatible with GL. In poorly differentiated neoplasms (blastic and pleomorphic types), cytologic features were sufficient to diagnose GL or malignant neoplasms; immunohistochemical techniques were useful to define their lymphoid nature. It is concluded that many GLs can be suspected or correctly diagnosed by routine endoscopic biopsy.

Abstract
Primary GI lymphoma is a rare clinical entity. A primary nodal tumor should be ruled out. Symptoms may not be localizing and B symptoms are less common. A tissue diagnosis, preferably by transmural biopsy for small intestinal involvement, often reveals a high-grade morphology. The staging work-up should include a bone marrow examination, although formal staging laparatomy is not always required. Patients with Mushoff stage IE or IIE1 disease do better than those with extraregional nodal disease or distant metastatic involvement. Surgical resection with clear margins is required in order to maximize the changes for cure. Chemotherapy or radiotherapy may give a survival advantage when used as adjuvant treatment for selected stage IE and IIE disease. Chemotherapy should be used after surgical debulking in more advanced disease in order to minimize the chance for bleeding or performation. Future randomized, multi-institutional trials will give more direction as to the best modes of management.

Abstract
One hundred thirteen patients with localized gastrointestinal lymphoma treated by surgery and postoperative irradiation between 1967 and 1985 were reviewed. At 15 years, actuarial survival of this group was 40.6%, with a cause-specific survival of 69.2% and a relapse-free rate of 64%. Two-thirds of relapses occurred at distant sites. In Stage IA and IIA patients with no residuum or with positive resection margins, (N = 90) only site of involvement and stage predicted for relapse. Age, histologic subtype group, and depth of bowel wall invasion did not affect relapse risk. In the very favorable group (Stage IA, IIA, no residuum or microscopic residuum), 8.4% of patients with stomach lymphoma relapsed compared to 25% of patients with small bowel lymphoma. The risk of early relapse was higher in those with Stage IIA small bowel lymphoma than those with Stage IA small bowel lymphoma. We continue to recommend adjuvant abdominal irradiation for patients with Stage IA, IIA completely resected stomach lymphoma and Stage IA completely resected small bowel lymphoma. We recommend combined modality therapy for patients with completely resected Stage IIA small bowel lymphoma and all other localized gastrointestinal lymphoma where visible residual disease is present.
