Abstract
Previous studies about the quality of life (QOL) in stomach cancer survivors focused on selected clinical parameters and did not consider the broader implications for overall health and QOL. We evaluated the impact of demographic and treatment-related factors on the QOL of stomach cancer survivors. We asked 391 stage I-III stomach cancer survivors who had been disease-free for at least 1 year after surgery to complete a demographic questionnaire, the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire, and its stomach module, QLQ-STO22.Survivors undergoing total gastrectomy reported greater eating restrictions than those undergoing subtotal gastrectomy. Receiving chemotherapy or radiotherapy did not significantly affect any QLQ-C30 or QLQ-STO22 scores. Role and emotional functioning improved with increasing age, and stomach-specific symptoms (pain, eating restrictions, and anxiety) lessened. Compared with female survivors, male survivors had better physical and role functioning. Smoking status was also a significant negative predictor of physical functioning and anxiety. Comorbidities and selected demographic characteristics had a greater effect than type of treatment on the QOL of post-operative stomach cancer patients.

Abstract
BACKGROUND Very few studies from Western centers have compared D2 and D3 dissection in the surgical treatment of gastric cancer. The aim of the prospective observational study reported here was to analyze the postoperative outcome and potential risk factors for complications following D2 and D3 lymphadenectomy. METHODS A total of 330 consecutive patients, of which 251 submitted to D2 lymphadenectomy and 79 were treated by D3 lymphadenectomy, were enrolled in the study. Twenty potential risk factors for morbidity and mortality were studied by means of univariate and multivariate analysis. RESULTS Overall morbidity and mortality rates were 34% (111 patients) and 4% (14 patients), respectively. Abdominal abscess, anastomotic leakage, pleuropulmonary diseases and pancreatitis were the most commonly observed complications. No differences in morbidity, surgical morbidity, mortality rates and mean hospital stay between D2 and D3 lymphadenectomy were found. Multivariate analysis revealed that American Society of Anesthesiologists' (ASA) class II/III versus class I, perioperative blood transfusions, and low albumin serum levels were independent predictors of postoperative complications. Age, surgical radicality (R1/R2 vs. R0) and low albumin serum levels independently predicted mortality. Mortality rate was .5% in the 203 patients aged 75 years or younger who underwent curative surgery. Most of deaths were observed in patients older than 75 years with low albumin serum levels or treated by non-curative surgery. CONCLUSIONS D2 lymphadenectomy represents a feasible procedure associated to acceptable morbidity and mortality rates. In specialized centers, D3 lymphadenectomy may be performed without increasing the risk of postoperative complications and associated deaths in carefully selected patients. These techniques should be avoided in subgroups of patients with a high risk of postoperative mortality.

Abstract
AIM: To investigate features of the posterior gastric artery (PGA) with respect to incidence, location and size by using autopsy subjects.
METHODS: Autopsies were performed on 72 cadavers of adults with no history of abdominal operations. The localization of the PGA, the distance between the root of the splenic artery and the origin of the PGA, and the external diameter of the PGA were examined.
RESULTS: The PGA was recognized in all patients. In 70 (97.2%) cadavers, the PGA branched from the splenic artery, and one female in this group had two PGAs. In 1 (1.4%) patient, the PGA originated from the root of the celiac trunk and in another (1.4%) patient, the PGA branched from the superior polar artery. Overall, the PGA extended for a length of 5.8-12.2 (mean, 8.4) cm from the root of the splenic artery, and the external diameter of the PGA was 1.2-3.2 (mean, 2) mm.
CONCLUSION: The anatomical features of the PGA can be readily observed and characterized by autopsy. This study has provided valuable information on the features of the PGA useful in the planning of surgical treatment.

Abstract
BACKGROUND The aim of this study was to determine how to select potential candidates for curative resection among advanced gastric patients with equivocal findings of para-aortic lymph node metastasis on computed tomography (CT). METHODS We analyzed the clinicopathologic results of 23 advanced gastric cancer patients who were diagnosed as having equivocal findings of para-aortic lymph node metastasis on a CT scan and who underwent gastrectomy with D2 and para-aortic lymph node dissection. RESULTS Twenty-two patients were male, and one patient was female. The median age of all study subjects was 52 years (range, 31-75 years). Sixteen underwent total gastrectomy, and seven underwent subtotal gastrectomy. The median number of A2 (suprarenal) lymph nodes harvested was 2 (range, 1-5), and that of B1 (infrarenal) lymph nodes was 6 (range, 1-17). Ten (43.5%) of the 23 patients were proven pathologically to have metastasis to para-aortic lymph nodes. Two patients with cT2 cancer had no metastatic para-aortic lymph node, whereas three patients with cT4 disease had metastatic para-aortic lymph nodes (P = .021). Seven (70.0%) of 10 patients with pathologic para-aortic lymph node metastasis experienced recurrence, whereas only 2 (15.4%) of 13 patients without experienced recurrence (P = .008). The Lauren classification was found to be an independent predictor of para-aortic lymph node metastasis (relative risk; .13; 95% confidence interval, .02-.83; P = .03). CONCLUSIONS More than half of gastric cancer patients with equivocal findings of para-aortic lymph node metastasis on CT are potential candidates for curative resection. The Lauren classification of gastric cancer in patients with equivocal CT findings of para-aortic lymph node metastasis would be helpful when deciding on clinical stage and treatment plans in these patients.

Abstract
Although the very high locoregional recurrence rates reported with limited D0/D1 surgery can be reduced with extended D2 gastrectomy for operable gastric cancer, overall relapse and survival rates remain poor and can only be improved with adequate perioperative adjuvant treatment. However, despite intensive research, no regimen has been established as standard. Meta-analyses have demonstrated a marginal survival benefit with adjuvant chemotherapy. Two recent large randomized trials for operable gastric cancer, the MAGIC trial and the INT-0116 trial, provide evidence that some patients may benefit from perioperative chemotherapy and chemoradiation, respectively. However, while both trials suggest an overall survival benefit with adjuvant treatment, they don't provide the harm-benefit ratio for specific subsets of patients wih different extent of surgery (D1 or D2) and tumor stage (early [T1,2]/advanced [T3,4]). This lack of evidence complicates current therapeutic adjuvant decisions. Estimating the risk of local and distant recurrence (high, moderate or low) after D1 or D2 surgery in various tumor stages and the expected harm-benefit ratio, the authors provide useful information for decisions on adjuvant chemotherapy with or withour radiotherapy in individual patients. Research on newer cytotoxic and targeted agents may improve treatment efficacy. Simultaneously, advances with microarray-based gene-expression profiling signatures may improve individualized treatment decisions. However, the validation and translation of these genomic classifiers as biomarkers into a completed 'bench-to-bedside' cycle for tailoring treatment to individuals is a major challenge and limits inflated expectations.

Abstract
Esophageal and gastric cancers are both common and deadly. Patients present most often after disease progression and survival is therefore poor. Due to demographic variability and recent changes in disease incidence, much emphasis has been placed on studying risk factors for both esophageal and gastric cancers. However, with increasing understanding of these diseases, low survival rates persist and continued intensive studies are necessary to optimize treatment plans. This review article discusses updates in the evolving epidemiology, clinical presentation, risk factors, and diagnostic and treatment modalities of esophageal and gastric cancers.

Abstract
There are still remarkable disparities in the treatment of gastric cancer between the East and West. Treatment outcomes for this disease have improved in Japan due to early detection and surgical resection with systematic node dissections, such as D2, whereas gastric cancer remains a virulent disease in Western countries. Differences in the types of surgery and their outcomes affect how adjuvant trials are conducted and interpreted. Recent Western randomized trials demonstrated the significant survival benefit of adjuvant chemoradiotherapy or intensive combination chemotherapy. However, baseline surgical quality and outcomes were quite different from those in Japan, and Japanese surgical/medical oncologists have not accepted the Western results. Several disparities are also evident in the results of chemotherapy trials for advanced gastric cancer. Although similar results were obtained with randomized studies using older regimens, the interpretation of the results differed between Japan and other countries. A combination of cisplatin and fluorouracil was used as the reference arm in ongoing randomized trials in most countries, whereas single-agent fluorouracil or S-1 alone was used in Japanese trials. Two triplet regimens have already demonstrated significant prolongation of survival in Western studies. However, these benefits seem to be marginal and these regimens may be replaced by newer regimens, which will soon be available in Europe and Asia, where a total of 2,600 patients have been accrued. Although these disparities between regions must be overcome, it is time for both Eastern and Western investigators to pursue further benefits by incorporating new agents into treatment regimens.

Abstract
BACKGROUND The survival benefit and morbidity after nodal dissection for gastric cancer remains controversial. We aimed to do a single-institution randomised trial to compare D1 (ie, level 1) lymphadenectomy with that of D3 (ie, levels 1, 2, and 3) dissection for gastric cancer in terms of overall survival and disease-free survival. METHODS From Oct 7, 1993, to Aug 12, 1999, 335 patients were registered. 221 patients were eligible, 110 of whom were randomly assigned D1 surgery and 111 of whom were randomly assigned D3 surgery, both with curative intent. Three participating surgeons had done at least 25 independent D3 dissections before the start of the trial, and every procedure was verified by pathological analyses. The primary endpoints were 5-year overall survival and 5-year disease-free survival. We also analysed risk of recurrence. Main analyses were done by intention to treat. This trial is registered at the US National Institute of Health website . FINDINGS Median follow-up for the 110 (50%) survivors was 94.5 months (range 62.9-135.1). Overall 5-year survival was significantly higher in patients assigned D3 surgery than in those assigned D1 surgery (59.5% [95% CI 50.3-68.7] vs 53.6% [44.2-63.0]; difference beteween groups 5.9% [-7.3 to 19.1], log-rank p=0.041). 215 patients who had R0 resection (ie, no microscopic evidence of residual disease) had recurrence at 5 years of 50.6% [41.1-60.2] for D1 surgery and 40.3% [30.9-49.7] for D3 surgery (difference between groups 10.3% [-3.2 to 23.7], log-rank p=0.197). INTERPRETATION D3 nodal dissection, compared with that of D1, offers a survival benefit for patients with gastric cancer when done by well trained, experienced surgeons.

Abstract
BACKGROUND Ionizing radiation (IR) is a potent agent in enhancing tumor control of locally advanced cancer and has been shown to improve disease-free and overall survival in several entities. However, the role of radiotherapy (RT) in the treatment of gastrointestinal tumors remains controversial because of the marked radiation sensitivity of neighboring organs frequently compromising application of high doses of ionizing radiation. METHODS The Medline and the Cochrane Library from 1980 until 2005 were searched using subject heading (MeSH) terms including "esophageal neoplasm", "gastric neoplasm", "pancreatic neoplasm" and "rectal neoplasm", in combination with the subheadings "radiotherapy", "chemotherapy". The term, "randomized controlled trial", was used to identify randomized trials. The proceedings of the annual meeting of the American Society for Therapeutic Radiology and Oncology from 1999 to 2004 and the annual meeting of the American Society of Clinical Oncology from 1999 until 2005 were searched. Ongoing trials were identified through the Physician Data Query database (www.cancer.gov/search/clinical_trials). RESULTS RT in combination with surgery enhances tumor control of locally advanced cancer disease and has been shown to improve disease-free and overall survival in rectal cancer. In esophageal adenocarcinoma, survival was prolonged with pre-operative chemo-radiation in a meta-analysis. In gastric cancer, post-operative chemo-radiation can be considered after limited lymphadenectomy. Evidence for improving survival remains to be shown for pancreatic cancer and hepatobiliary carcinoma. In colon cancer, post-operative chemotherapy has proven to prolong survival. The impact of RT seems to be most prominent in the pre-operative setting in patients treated with curative intent. CONCLUSIONS Pre-operative RT or pre-operative chemo-radiation may be considered in individual cases, but should not be used routinely for gastro-intestinal carcinoma, except for rectal carcinoma. In many studies, pre-operative radiotherapy/chemo-radiation yielded promising results and merits validation in large controlled trials.

Abstract
Outcomes in patients with gastric cancer in the United States remain disappointing, with a five-year overall survival rate of approximately 23%. Given high rates of local-regional control following surgery, a strong rationale exists for the use of adjuvant radiation therapy. Randomized trials have shown superior local control with adjuvant radiotherapy and improved overall survival with adjuvant chemoradiation. The benefit of adjuvant chemoradiation in patients who have undergone D2 lymph node dissection by an experienced surgeon is not known, and the benefit of adjuvant radiation therapy in addition to adjuvant chemotherapy continues to be defined.
In unresectable disease, chemoradiation allows long-term survival in a small number of patients and provides effective palliation. Most trials show a benefit to combined modality therapy compared to chemotherapy or radiation therapy alone.
The use of pre-operative, intra-operative, 3D conformal, and intensity modulated radiation therapy in gastric cancer is promising but requires further study.
The current article reviews the role of radiation therapy in the treatment of resectable and unresectable gastric carcinoma, focusing on current recommendations in the United States.

Abstract
BACKGROUND Curative gastrectomy is a promising approach for the treatment of gastric cancer; however, the optimal extent of lymph node dissection for advanced cancer remains controversial. The aim of this multi-institutional study was to evaluate the feasibility of D3 gastrectomy (para-aortic lymph node dissection) for advanced gastric cancer. The surgical results of D2 and D3 gastrectomy (para-aortic lymph node dissection) were retrospectively compared. METHODS A series of 580 advanced gastric cancer patients were registered between 1992 and 2000. Of these, 430 underwent D2 gastrectomy and 150 underwent D3 gastrectomy. Survival time, prognostic factors, postoperative morbidity/mortality, and pattern of recurrence were compared. RESULTS There was no significant difference in survival time between D2 and D3 patients. However, the survival times of D3 patients with tumor diameters measuring 50 to 100 mm or with pN1 disease were significantly longer than those of the corresponding D2 patients. Analysis of the survival of patients with tumor diameters measuring 50 to 100 mm revealed that D3 gastrectomy conferred a survival advantage only to patients with pN2 disease. The incidence of lymphatic recurrence was lower in D3 patients with 50- to 100-mm tumors than in the corresponding D2 patients. CONCLUSIONS D3 gastrectomy might be beneficial in patients with advanced pN2 gastric cancer within the group with tumors measuring 50 to 100 mm. A randomized controlled trial of patients with 50- to 100-mm tumors should be performed to test the validity of this preliminary result.

Abstract
BACKGROUND There is controversy about the best therapeutic surgical approach for treatment of patients with T4 gastric cancer. STUDY DESIGN We used univariate and multivariate analyses to review the surgical outcomes and prognostic factors of 117 patients who underwent surgery for T4 gastric carcinoma. RESULTS Curative resection was performed in 38 (32.4%) patients, with the pancreas being the most frequently resected organ. The 5-year survival rate was 16.0% and the median survival time (MST) was 11 months for all 117 registered patients. The 5-year survival rates and MSTs in patients after curative and noncurative resection were 32.2% versus 9.5% and 20 months versus 8 months, respectively. These values differed considerably between the two groups (p < 0.0001). Curability was an independent prognostic factor among all registered patients, including those who underwent noncurative resection. A relatively small tumor diameter (< 100 mm) and few lymph node metastases (six or fewer metastatic lymph nodes) were independent prognostic factors when curative resection could be performed. Postoperative morbidity and mortality were acceptable after curative combined resection. CONCLUSIONS We recommend the use of aggressive combined resection of adjacent organs, with extended lymph node dissection, for patients with T4 gastric carcinoma in whom curative resection can be used; that is, those with few metastatic lymph nodes (six or less) and a relatively small tumor diameter (100 mm). But noncurative resection should be avoided in patients with T4 gastric cancer.

Abstract
Surgery is currently the only potentially curative treatment for gastric cancer. Since the inception of the gastrectomy for cancer of the stomach, there has been debate over the bounds of surgical therapy, balancing potential long-term survival with perioperative morbidity and mortality. This review delineates the current role of surgery in preoperative staging, curative resection, and palliative treatment for gastric cancer.

Abstract
BACKGROUND Evidence suggests that baseline quality of life (QOL) scores are independently prognostic for survival in patients with cancer, but the role of QOL data in predicting short-term outcome after surgery is uncertain. This study assessed the association between QOL scores and short-term outcomes after surgery for oesophageal and gastric cancer. METHODS Consecutive patients selected for oesophagectomy or total gastrectomy between November 2000 and May 2003 completed the European Organization for Research and Treatment of Cancer's quality of life questionnaire, QLQ-C30. Multivariable regression models, adjusting for known clinical risk factors, were used to investigate relationships between QOL scores, major morbidity, hospital stay and survival status at 6 months. RESULTS Of 130 patients, 121 completed the questionnaire (response rate 93.1 per cent). There were 29 major complications (24.0 per cent) and 22 patients (18.2 per cent) died within 6 months of operation. QOL scores were not associated with major morbidity but were significantly related to survival status at 6 months after adjusting for known clinical risk factors. A worse fatigue score of 10 points (scale 0-100) corresponded to an increase in the odds of death within 6 months of surgery of 37.4 (95 per cent confidence interval (c.i.) 12.4 to 67.8) per cent (P = 0.002). Pretreatment social function scores were moderately associated with hospital stay (P = 0.021); a reduction in social function by 10 points corresponded to an increase in hospital stay of 0.93 (95 per cent c.i. 0.12 to 1.74) days. CONCLUSION QOL scores supplement standard staging procedures for oesophageal and gastric cancer by providing prognostic information, but they do not contribute to perioperative risk assessment.

The overall 5-year survival of patients with gastric cancer is only 23% in the US compared with 60% in Japan. For Western patients, detecting the disease earlier and applying treatment quality control could substantially improve clinical outcome. For the treatment of gastric cancer, complete tumor resection, whenever feasible, is the standard treatment. Resection of the primary tumor (partial or total gastrectomy) is based on standardized criteria of the tumor, such as location, stage, histology, and surgical margins. The extent of regional lymphadenectomy required, however, has been a matter of considerable debate. Emerging evidence from the latest randomized controlled trials show that extended (D2) lymphadenectomy is safe and able to cure 20% of patients with N2-disease compared with 0% treated with limited D1 dissection, provided that the optimal surgical technique is used. Estimates suggest that this N2-specific subgroup advantage reflects a potential absolute overall survival benefit of 3-6%. Postoperative decisions about adjuvant chemotherapy and radiotherapy are based on pathologic staging, the extent of surgery performed (D0/D1 vs D2/D3) and the risk-benefit ratio. Recurrence-risk and mortality-risk reduction is achievable with a carefully planned relapse-prevention guided therapeutic strategy. Patient-related factors (tumor features and expected recurrence-risk magnitude) and treatment-related factors (surgical experience, adjuvant treatment risk-benefit ratio) should be considered on an individual basis. In future, genomic-based approaches will help to provide a more personalized therapeutic approach and improve patient outcome.

Abstract
Although studies have shown that early oral feeding after abdominal surgery is feasible, the optimal dietary schedule has not been established. This study was conducted prospectively to compare the clinical outcome of patient-controlled dietary schedule with that of conventional dietary schedule after gastric resection for early cancer. Patients in the patient-controlled diet (PC) group (n = 53) received a solid diet on demand; patients in the conventional regimen (CR) group (n = 50) received a solid diet from postoperative day (POD) 10. All patients underwent distal gastrectomy for early gastric cancer. A liquid diet was tolerated by the PC group on POD 2, and a solid diet was taken on POD 6 after gastrectomy, earlier than in the CR group. The postoperative hospital stay was 18.5 +/- 5.9 days (10-40) in the PC group, versus 21.7 +/- 8.8 days (14-57) in the CR group (p = 0.02). Patients in the PC group had a higher daily oral intake of calories on POD 10 than those in the CR group (p = 0.02). Changes in body weight and serum albumin during the postoperative period and after discharge, and the incidence of complications and variances from clinical pathways did not show significant differences between the two groups. The PC schedule was feasible after distal gastrectomy for early gastric cancer. It improved the clinical outcome, with a shorter postoperative hospital stay and a higher oral energy intake on early phase, compared with the CR schedule. Moreover, the PC approach was useful for establishing the optimal dietary schedule and improving the clinical pathway.

Abstract
The Dutch Gastric Cancer Study Group Trial was the first clinical phase III trial to be carried out in the field of cancer surgery. In spite of the excellent quality of the trial, it was heavily criticized for the poor quality of the treatment itself. Actually, the hospital mortality after the new surgical treatment (D2 lymph node dissection for gastric cancer) was unacceptably high. In surgical trials, special attention should be paid to quality issues specific to surgery. The first and the most important issue is the quality of treatment given. Reproducibility, homogeneity, and verifiability are the greatest problems in surgical trials. There are also some patient factors. If the patient is old, or fragile, or obese, the results of the surgical treatment can easily be affected by these factors. The surgeon can also be a prognostic factor, especially in complicated procedures or those requiring experience and training. Experience, including postoperative care, and dexterity affect the results. If surgeons do not know how to manage complications, mortality becomes very high. Because blinding is impossible in surgical trials, the treatment may easily be affected by personal preference or prejudice. To minimize the influence of these hampering factors, the procedures should be defined in as detailed a way as possible. If pretrial training or a feasibility study (phase II) is needed, it should be carried out properly for the patients' sake. An excellent design and excellent statistical analysis cannot lead to meaningful results if the quality of treatment is poor. Nonsense in, nonsense out.

Abstract
BACKGROUND Extended lymphadenectomy for gastric carcinoma has been associated with high mortality and morbidity rates in several multicentre randomized trials. METHODS Using data from 523 patients registered for a prospective randomized trial comparing extended (D2) and superextended (D3) lymphadenectomies, risk factors for overall complications and major surgical complications (anastomotic leakage, intra-abdominal abscess and pancreatic fistula) were identified by multivariate logistic regression analysis. RESULTS Mortality and morbidity rates were 0.8 per cent (four of 523) and 24.5 per cent (128 of 523) respectively. Pancreatectomy (relative risk 5.62 (95 per cent confidence interval (c.i.) 1.94 to 16.27)) and prolonged operating time (relative risk 2.65 (95 per cent confidence interval 1.34 to 5.23)) were the most important risk factors for overall complications. A body mass index of 25 kg/m2 or above, pancreatectomy and age greater than 65 years were significant predictors of major surgical complications. CONCLUSION Pancreatectomy should be reserved for patients with stage T4 disease. Age and obesity should be considered when planning surgery.

Abstract
AIM: To explore the feasibility of performing gastrectomy with D2 lymphadenectomy in gastric cancer patients with liver cirrhosis.
METHODS: A total of 7 178 patients were admitted with a diagnosis of liver cirrhosis from January 1993 to December 2003. We reviewed the records of 142 patients who were diagnosed with liver cirrhosis and gastric adenocarcinoma during the same period. Gastrectomy with D2 lymph node dissection for carcinoma of the stomach was performed in 94 patients with histologically proven hepatic cirrhosis.
RESULTS: All but 12 patients were classified as Child’s class A. Only 35 patients (37.2%) were diagnosed with cirrhosis before operation. Seventy-three patients underwent a subtotal gastrectomy (77.7%) and 21 patients (22.3%) underwent a total gastrectomy, each with D2 or more lymph node dissection. Two patients (3.8%) who had prophylactic intra-operative drain placement, died of postoperative complications from hepatorenal failure with intractable ascites. Thirty-seven patients (39.4%) experienced postoperative complications. The extent of gastric resection did not influence the morbidity whereas serum aspartate aminotransferase level (P = 0.011) and transfusion did (P = 0.008). The most common postoperative complication was ascites (13.9%) followed by wound infection (10.6%).
CONCLUSION: We concluded that the presence of compensated cirrhosis, i.e. Child class A, is not a contraindication against gastrectomy with D2 or more lymph node dissection, when curative resection for gastric cancer is possible. Hepatic reserve and meticulous hemostasis are the likely determinants of operative prognosis.

Abstract
BACKGROUND The outcome and quality of surgical treatment in gastric cancer are closely associated with specific postoperative morbidity and mortality, in addition to an oncosurgically adequate resection status. In this context, a preventive concept of decreasing the insufficiency rate of esophageal anastomosis may have a great impact. METHOD Over a time period of 12 months (from 1 January 2002 to 31 December 2002), 1,199 patients (from 80 East German hospitals) with gastric carcinoma, carcinoma of the esophagogastral junction, or gastrointestinal stroma tumor (GIST) were enrolled in this prospective multicenter observational study with the aim of evaluating their early postoperative outcome. By means of a logistic regression analysis, independent variables, which alter significantly the healing of esophagojejunal anastomosis, were determined; in addition, their clinical impact on preventive management to lower the insufficiency rate of esophageal anastomosis was investigated. RESULTS In 1,139 patients, histological investigation revealed gastric carcinoma. Out of these patients, 1,031 subjects underwent surgical intervention (90.5%) and 891 individuals underwent resection (86.4%). In 813 patients, radical resection (subtotal resection and gastrectomy) was executed (78.9%), whereas in 726 cases, R(0) resection was achieved (81.5%). Gastrectomy was the preferred procedure in 649 patients, resulting in a gastrectomy rate of 62.9% relating to all patients who underwent operation (curative and palliative intention, 80.3% and 19.7%, respectively). The insufficiency rate of esophagojejunal anastomosis was 5.7% (37/649). Neither the comparison between the various procedures for the reconstruction of the esophagojejunal passage and anastomosing techniques after gastrectomy nor that between gastrectomies with curative and palliative intention revealed any significant difference. Dysphagia and gastric outlet syndrome due to a stenosis were determined as independent variables by a logistic regression analysis of all preoperative and intraoperative variables. In all patients with gastric carcinoma, both parameters were recorded in 9.9% (113/1,139) and 6.7% (76/1,139), respectively. CONCLUSION Dysphagia and gastric stenosis, which significantly influence the healing of esophagojejunal anastomosis after gastrectomy, are considered characteristics of an advanced tumor growth and a pretherapeutic lack of an adequate nutrition. This emphasizes the necessity of an early diagnosis of gastric cancer in order to lower perioperative morbidity. In addition, dysphagia is commonly associated with an obstruction of the upper gastrointestinal tract, which can lead to nutritional deficits, and thus deserves specific care during preventive management.

Abstract
Worldwide, gastric cancer is one of the leading causes of cancer-related death. The mainstay of curative treatment is radical surgery. But even with optimal surgical resection, the prognosis remains modest in the Western world. Numerous attempts have been undertaken to improve clinical outcome. More extensive lymph node dissection, adjuvant radiotherapy and adjuvant chemotherapy did not result in a survival benefit in randomized trials. Only postoperative chemoradiotherapy has proven to be valuable in prospective randomized trials. Questions are to be answered about optimization of surgery, radiotherapy and chemotherapy, and fine tuning of the three modalities. One of the key issues that should be addressed is whether pre- or postoperative chemoradiotherapy will benefit survival or locoregional control in the case of optimal surgery with an "over-D1" lymphadenectomy and without splenectomy. In this article the most relevant literature on locoregional treatment in operable gastric cancer will be reviewed and future strategies will be discussed.

Abstract
BACKGROUND The operative mortality in gastric cancer surgery has been reported to be higher with D2 lymphadenectomy than with D1 in the West. The modified radical lymphadenectomy (D1.5) may be safer than D2 under these circumstances. This study was aimed to determine whether D1.5 would deteriorate long-term survival as compared with D2. METHOD Since the concept of the extent of lymphadenectomy varied among the surgeons, 461 patients who underwent curative gastrectomy for T2-4 gastric adenocarcinoma were retrospectively categorized into three groups according to the surgeon: D1 with dissection along the left gastric and common hepatic arteries (D1.5); lymphadenectomy between D1.5 and D2; D2 or more extended dissection. RESULTS No differences were found in the survival rates among the three groups within each of the T2a, T2b, and T3 categories. According to a multivariate analysis using Cox's proportional hazard model, the classification according to the surgeons had no survival impact (p>0.8). CONCLUSION D1.5 lymphadenectomy resulted in a survival rate that was almost equal to that of D2. The use of D1.5 instead of D2 can be an attractive option to be compared with D1 in future trials.

Abstract
There are many factors that are of influence on gastric cancer treatment. The only way to survive is complete locoregional control. More extended dissections should lead to better outcome, but increased morbidity and mortality probably offset its long-term effect in survival in randomised studies. In this article the factors of influence on outcome of gastric cancer treatment such as the extent of lymph node dissection, splenectomy, pancreatectomy, age, volume and additional treatments are discussed. A literature review of these factors in relation to the latest results of the Dutch Gastric Cancer Trials are presented. If morbidity and mortality can be reduced there might be an advantage of extended lymph node dissection. Splenectomy and pancreatectomy should be performed only in case of direct in growth from the tumour into these organs. Centralisation of gastric cancer treatment should be achieved in order to improve results and to facilitate research. By refining selection criteria in the treatment of gastric cancer further improvements are to be expected.

Abstract
Despite surgical R0 resections, patients with gastric cancer stage UICC II-III have a high risk of recurrence and metachronic metastases. Preliminary evidence exists that adjuvant chemotherapy or neoadjuvant chemo(radio)therapy protocols may improve the prognosis of these patients undergoing surgery of gastric cancer with curative intention. As for palliative regimens, 5-fluorouracil and cisplatin are integral components of such (neo)adjuvant strategies. Upcoming cytostatic agents, i.e. irinotecan, docetaxel, oxaliplatin, and oral fluoropyridines are currently under investigation in new multimodality treatment regimens and may further increase R0 resection rates and may prolong disease-free and overall survival in the treatment of advanced localized gastric cancer.

Abstract
D2 lymphadenectomy has been the mainstay of treatment for every stage of gastric cancer including early gastric cancer in Japan. However, the use of conventional D2 nodal dissection is being challenged. There was a recent improvement in techniques for preoperative diagnosis and perioperative diagnosis. Less extensive surgeries to maintain patients' quality of life have been introduced as standard treatment for some forms of early gastric cancer in the Gastric Cancer Treatment Guidelines 2001 (The Japanese Gastric Cancer Association). Superextended dissection (more than D2) for non-early gastric cancer is set at investigational treatment. Japanese surgeons are now aiming at wide variations of surgical treatment according to the stage of disease based on new procedures. Further evaluations are proceeding to prove superior to standard techniques.
