Abstract
Background: Gastric cancer is one of the most common cancers among Iranian men and women. Objectives: The aim here was to investigate different histopathologic types and features of this cancer in association with selected prognostic variables. Methods: A retrospective cross-sectional study was performed to reevaluate the pathologic samples of 100 cases of gastric cancer referred to Shohadaye Tajrish Hospital, Tehran, Iran from 2017 to 2022. Results: We evaluated 100 cases of gastric cancer in this study. They had a mean age of 62.4 ± 13.44 years old (range 28 - 84 years) and were mostly men (n = 66, 66 %). On histopathologic evaluation, tubular carcinoma was the most common type (n = 45, 45%). We found a statistically significant correlation between the histologic type and perineural invasion (P-value = 0.024), lymphovascular invasion (P-value < 0.001), tumoral involvement of surgical margin (P-value = 0.012 ), infiltration depth of the primary tumor (pT) (P-value = 0.049) , number of metastatic lymph nodes (pN) (P-value = < 0.001) , tumor location in the antrum (P-value=0.033) and body (P-value = 0.013) , and tumor size (P-value = 0.002 and P-value = 0.031 in small and large size groups respectively). Conclusions: According to the findings, histologic type of gastric cancer correlates with perineural invasion, lymphovascular invasion, tumoral involvement of the surgical margin, pT, pN, and tumor location and size.

Abstract
OBJECTIVE This study aimed to preoperatively differentiate primary gastric lymphoma from Borrmann type IV gastric cancer by heterogeneity nomogram based on routine contrast-enhanced computed tomographic images. METHODS We enrolled 189 patients from 2 hospitals (90 in the training cohort and 99 in the validation cohort). Subjective findings, including high-enhanced mucosal sign, high-enhanced serosa sign, nodular or an irregular outer layer of the gastric wall, and perigastric fat infiltration, were assessed to construct a subjective finding model. A deep learning model was developed to segment tumor areas, from which 1680 three-dimensional heterogeneity radiomic parameters, including first-order entropy, second-order entropy, and texture complexity, were extracted to build a heterogeneity signature by least absolute shrinkage and selection operator logistic regression. A nomogram that integrates heterogeneity signature and subjective findings was developed by multivariate logistic regression. The diagnostic performance of the nomogram was assessed by discrimination and clinical usefulness. RESULTS High-enhanced serosa sign and nodular or an irregular outer layer of the gastric wall were identified as independent predictors for building the subjective finding model. High-enhanced serosa sign and heterogeneity signature were significant predictors for differentiating the 2 groups (all, P < 0.05). The area under the curve with heterogeneity nomogram was 0.932 (95% confidence interval, 0.863-0.973) in the validation cohort. Decision curve analysis and stratified analysis confirmed the clinical utility of the heterogeneity nomogram. CONCLUSIONS The proposed heterogeneity radiomic nomogram on contrast-enhanced computed tomographic images may help differentiate primary gastric lymphoma from Borrmann type IV gastric cancer preoperatively.

Br J Surg 2014; 101:1560-5. [PMID: 25200278 DOI: 10.1002/bjs.9632] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2014] [Revised: 05/25/2014] [Accepted: 07/24/2014] [Indexed: 12/22/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy has been shown to improve the rate of complete (R0) resection and downstaging in patients with localized gastric cancer. There are few reports, however, regarding its impact on postoperative morbidity and mortality. The aims of this study were to analyse complication and mortality rates after neoadjuvant chemotherapy using a modified regimen of folinic acid, 5-fluorouracil and oxaliplatin (mFOLFOX6) for locally advanced gastric cancer (AGC), compared with rates in patients who underwent surgery without neoadjuvant chemotherapy. METHODS Data were collected from patients with AGC enrolled in a phase II trial of four cycles of neoadjuvant mFOLFOX6 followed by surgery, between January 2005 and June 2008 at two of three institutions, and compared with those from a cohort of patients with AGC who underwent surgery alone at one of the institutions in 2006. RESULTS Among 51 patients who received neoadjuvant chemotherapy, there were no deaths and a morbidity rate of 24 per cent after surgery. Comparison of 48 patients in one institution who received neoadjuvant chemotherapy with 92 patients who had surgery alone in the same institution showed no increase in postoperative morbidity (23 versus 29 per cent; P = 0·417). Combined resection was the only risk factor for postoperative morbidity after neoadjuvant chemotherapy. CONCLUSION Neoadjuvant chemotherapy with mFOLFOX is a safe treatment for patients with localized AGC, and does not increase postoperative morbidity or mortality.

Abstract
The current study presents a retrospective comparison, performed at a single academic center, of preoperative chemoradiation (CRT) and perioperative chemotherapy (CT) in addition to surgery in locally advanced but resectable adenocarcinoma of the esophagogastric junction (AEG). A total of 29 consecutive patients with locally advanced AEGs were retrospectively analyzed. Treatment consisted of preoperative CRT (mean dose, 45.0 Gy) plus two cycles of CT with cisplatin and 5-FU or perioperative CT with epirubicin, cisplatin and capecitabine (three cycles preoperatively and postoperatively). Within four to six weeks following preoperative treatment, surgical therapy was performed. Median overall survival was 21.0 months in the perioperative CT group versus 41.7 months in the CRT group [P=0.36; hazard ratio (HR), 1.50; 95% confidence interval (CI), 0.58–3.84]. Three-year survival rates were 55 and 38%, respectively, in favor of the CRT group, and progression-free survival was 20.0 months in the CT group compared with 24.1 months in the CRT group (P=0.71; HR, 1.19; 95% CI, 0.46–3.05). The total number of major surgical complications was almost equal in the two groups. Margin-free resections were achieved in all patients of the CRT group, but only 76.9% of the CT group (P=0.05). In addition, significantly higher R0 resection rates and an increased number of pathological complete remissions were demonstrated in the CRT group compared with those of the CT group. These results appear to indicate a trend for improved progression-free and overall survival for the CRT group. As postoperative morbidity and mortality rates were similar in the two groups, the results support the use of CRT for patients with advanced AEG tumors.

Abstract
INTRODUCTION Gastric cancer is a heterogeneous disease, whose pathological and clinical patterns have changed in the last decades. In most western countries, decreases in incidence and mortality and a proximal migration have been reported. The clinical and pathological trends in an European country with high prevalence of gastric cancer were reviewed, based on the patients treated at a University Hospital. METHODS Analysis of a prospective database with 1618 patients who underwent surgery for gastric cancer in the last 3 decades. The patients were divided in 3 groups according to decades and the cohorts were analyzed according to demographic, surgical and pathological factors. RESULTS The mean age increased from 59.8 to 65.6 years. Antral tumors and intestinal cancer were the most frequent. The rate of complete resection increased as well as the percentage of total gastrectomies and D2-type lymphadenectomies. There was an increase both in early stage carcinomas and in surgically treated Stage-IV carcinomas. The median overall crude survival almost doubled from 14 to 22 months (p = 0.003), but once stratified for stage, only in stage II patients could we observe a significant increase in survival time. (29-47 months; p = 0.047). CONCLUSION The proximal migration described for Western Europe was not observed and the intestinal-type carcinoma is still the most frequent. We are treating older patients, often with more advanced disease. In spite of an increasing surgical aggressiveness, the prognosis has only been significantly improved in Stage-II cancers. The prognosis for advanced cancer is still dismal, hence the need for effective adjuvant treatments.

Abstract
Background Gastric carcinoma and primary gastric lymphoma (PGL) are the two most common malignancies in stomach. The purpose of this study was to screen and validate a biomarker of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for distinguishing advanced gastric carcinoma (AGC) from PGL for clinical applications. Methodology/Principal Findings We reviewed PET/CT scans collected from January 2008 to April 2012 of 69 AGC and 38 PGL (14 low-grade mucosa-associated lymphoid tissue [MALT], 24 non-MALT aggressive non-Hodgkin lymphoma [ANHL]) with a focus on FDG intensity (maximum standardized uptake value [SUVmax]) of primary lesions and its CT-detected abnormalities, including maximal gastrointestinal wall thickness (THKmax) and mucosal ulcerations. Gastric FDG uptake was found in 69 (100%) patients with AGC and 36 (95%, 12 MALT vs. 24 ANHL)with PGL. The presence of CT-detected abnormalities of AGC and PGL were 97% (67/69) and 89% (12 MALT vs. 22 ANHL), respectively. After controlling for THKmax, SUVmax was higher with ANHL than AGC (17.10±8.08 vs. 9.65±5.24, p<0.05) and MALT (6.20±3.60, p<0.05). THKmax did not differ among MALT, ANHL and AGC. Mucosal ulceration was more common with AGC (n = 9) than PGL (n = 2),but the difference was not statistically significant (p>0.05). Cross-validation analysis showed that for distinguishing ANHL from AGC, the classifier with SUVmax as a feature achieved a correct classification rate of 81% with thresholds 13.40±1.12 and the classifier with SUVmax/THKmax as a feature achieved a correct classification rate of 83% with thresholds 7.51±0.63. Conclusions/Significance SUVmax/THKmax may be as a promising biomarker of FDG-PET/CT for distinguishing ANHL from AGC. Structural CT abnormalities alone may not be reliable but can help with PET assessment of gastric malignancies. 18F-FDG PET/CT have potential for distinguishing AGC from PGL at the individual level.

Abstract
Clinical trials of suicide gene therapy have achieved limited success, which suggests a need for improvement. Angiogenesis plays a crucial role in the progression of cancers, which is greatly regulated by vascular endothelial growth factor (VEGF).The current study was designed to evaluate the anti-tumor effects of VEGF siRNA in combination with fusion suicide gene yCDglyTK. Introduction of a VEGF-targeted small hairpin RNA (shVEGF) to CDTK/5-FC system could induce cell apoptosis more effectively and decrease micro vessel density in xenograft tissue, thus resulted in a significant tumor growth delay in SGC7901 xenografts. These findings for the first time suggest the potential of combination gene therapy using suicide gene therapy and anti-angiogenesis gene therapy.

Abstract
BACKGROUND The pattern of gastric cancer in the Western world is changing, with an increased proportion of tumours in the upper stomach. The aim of this study was to investigate changes in clinicopathological features and survival of patients with resected gastric cancer at a single institution, in an area of high incidence in the Far East. METHODS Clinical features and pathological findings were compared in patients with gastric cancer who underwent gastrectomy at Seoul National University Hospital during four consecutive periods (1986-1990, 1991-1995, 1996-2000 and 2001-2006). RESULTS There were 12 026 patients. The mean age increased from 53·4 years in the first period to 57·4 years in the last (P < 0·001). The proportion of patients aged 70 years or older also increased, reaching 16·1 per cent in the final period. Upper-third cancer increased from 5·3 per cent in the first period to 14·0 per cent in the fourth (P < 0·001). Early gastric cancer (pathological T1) increased continuously over the four time intervals, from 24·8 to 48·9 per cent (P < 0·001). The overall 5-year survival rate increased from 64·0 per cent in the first period to 73·2 per cent at the end (P < 0·001), and this survival improvement was apparent in patients aged 40 years or more. CONCLUSION The mean age of patients with gastric cancer has increased during the past 20 years. The proportion of early gastric cancer and overall survival have gradually increased, especially in patients aged over 40 years.

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 Although the incidence of adenocarcinoma of the stomach has decreased over the past several decades, gastric cardia carcinoma has increased over the same period. METHODS The clinicopathologic characteristics and immunohistochemical staining results of 21 proteins were investigated in 165 patients with cardia carcinoma, including 74 patients with true cardia carcinoma and 91 patients with subcardia carcinoma, and the results were compared with the results from 564 patients with noncardia carcinoma. RESULTS In the clinicopathologic analysis, patients who had cardia carcinoma tended to have tumors with poorly differentiated histology according to the World Health Organization classification system (P = 0.012), diffuse type according to the Lauren classification system (P = 0.049), and advanced pathologic TNM stage (P < 0.001). On immunohistochemical staining, loss of the p16 (P = 0.038) and smad4 (P < 0.001) tumor suppressor genes was more frequent in cardia carcinoma than in noncardia carcinoma. Carcinoembryonic antigen and CD44 overexpression were more frequent in patients with cardia carcinoma (P < 0.05). Conversely, patients who had cardia carcinoma exhibited less frequent expression of MUC1 (P = 0.008) and MUC5AC (P = 0.006) compared with patients who had noncardia carcinoma. Epstein-Barr virus infection was more common in patients with cardia carcinoma (P < 0.001). In the survival analysis, the patients with cardia carcinoma had a poorer prognosis. In the multivariate analysis, tumor location in the cardia was confirmed as an independent, poor prognostic factor in patients with gastric carcinoma. CONCLUSION Cardia carcinoma and noncardia carcinoma differed in their clinicopathologic characteristics and in their alterations of gene expression, as evaluated by immunohistochemistry. The current results support the hypothesis that cardia carcinoma forms a specific category of gastric carcinoma that is distinct from noncardia carcinoma.

Abstract
In advanced gastric cancer, palliation of symptoms, rather than cure, is often the most appropriate goal of patient management. There are important differences among patients undergoing non-curative operations for gastric cancer. The literature to date is limited, in part, by imprecise use of the term palliative. In clinical decision-making, the potential benefits of proposed procedure must be balanced against the duration of hospitalization, treatment of complications, and requirements for additional palliation. Studies designed to measure palliative interventions would benefit from precise designations of palliative intent inpatients receiving non-curative operations.

Abstract
BACKGROUND Effective palliation rather than cure is often the most appropriate goal in the management of patients with advanced gastric cancer. The literature to date is limited by the imprecise use of the term palliative and subsequent variable designation of patients into evaluable groups. STUDY DESIGN Between July 1985 and July 2001, 1,595 patients were entered into a prospective database after undergoing a resection for gastric adenocarcinoma. Patients who received a noncurative (R1/R2) resection were identified. A procedure was defined as palliative if it was performed explicitly to palliate symptoms or improve quality of life. RESULTS Three hundred seven patients received a noncurative gastric resection. The operation was palliative in 48% (147/307) and nonpalliative in 52% (160/307). Palliative operations included an esophageal anastomosis less frequently (46% versus 69%, p < 0.001) and had a less extensive lymphadenectomy performed compared with nonpalliative operations. Surgical intent did not alter operative morbidity (54%) or mortality (6%) significantly. The overall median survival after a noncurative gastric resection was 10.6 months and was independently associated with operations performed with explicit palliative indications (8.3 months [palliative] versus 13.5 months [nonpalliative], p < 0.001) and patient age > 65 years. CONCLUSIONS There are important differences among patients undergoing noncurative operations for gastric cancer. Studies designed to measure palliative interventions would benefit from precise designations of palliative intent in patients receiving noncurative operations.

Abstract
Patients with gastric cancer have a variety of immunological abnormalities. In the present study the lymphocytes and their subsets were determined in the peripheral blood of patients with gastric cancer (N = 41) both before and after surgical treatment. The percent of helper/inducer CD4 T cells (43.6 +/- 8.9) was not different after tumor resection (43.6 +/- 8.2). The percent of the cytotoxic CD8+ T cell population decreased significantly, whether patients were treated surgically (27.2 +/- 5.8%, N = 20) or not (27.3 +/- 7.3%, N = 20) compared to individuals with inflammatory disease (30.9 +/- 7.5%) or to healthy individuals (33.2 +/- 7.6%). The CD4/CD8 ratio consequently increased in the group of cancer patients. The peripheral blood lymphocytes of gastric cancer patients showed reduced responsiveness to mitogens. The defective blastogenic response of the lymphocytes was not associated with the production of transforming growth factor beta (TGF- ) since the patients with cancer had reduced production of TGF- Beta1 (269 +/- 239 pg/ml, N = 20) in comparison to the normal individuals (884 +/- 175 pg/ml, N = 20). These results indicate that the immune response of gastric cancer patients was not significantly modified by surgical treatment when evaluated four weeks after surgery and that the immunosuppression observed was not due to an increase in TGF- 1 production by peripheral leukocytes.

Abstract
UNLABELLED Background and Objective We wanted to determine the role of additional photodynamic therapy in a multimodal approach for the treatment of patients with advanced cancer of the gastro-esophageal junction. Study Design/Materials and Methods We reviewed 53 patients, after endoluminal palliation, with advanced cancer of the gastro-esophageal junction. Combined dilatation and retrograde tumor disobliteration with Nd-YAG laser before photodynamic therapy (PDT), brachyradiotherapy, or both, became necessary in 12 patients. Brachyradiotherapy was carried out in all patients. PDT before brachyradiotherapy was performed in 25 patients. The endoluminal treatment was completed by external beam irradiation in 30 patients (15 cases with PDT and 15 without PDT) with an at least fair performance status. RESULTS Photodynamic therapy showed a significant difference regarding the mean opening of the tumor stenosis (mean, 6.4 mm; P = 0.0002), the mean decrease in tumor length (3.1 cm; P = 0.00001) and the increase in median survival (13. 8 months; P = 0.001). The combined multimodal approach by using PDT, brachyradiotherapy and external beam irradiation showed a median survival of 16.8 months. However, additional external beam irradiation showed no significant difference (P = 0.11). The rate of severe complications was 5.7%. The mortality rate was 1.9%. CONCLUSION Photodynamic therapy has been shown to be an effective treatment for palliation of advanced cancer at the gastro-esophageal junction. The use of PDT combined with irradiation was associated with an acceptable survival rate, low rates of complications and reasonable quality of life.

Abstract
BACKGROUND Several studies have investigated the possible role of the adjuvant chemotherapy after curative resection for gastric cancer failing to show a clear indication; previous meta-analyses suggested small survival benefit of adjuvant chemotherapy, but the statistical methods used were open to criticisms. MATERIALS AND METHODS Randomised trials were identified by means of Medline and CancerLit and by selecting references from relevant articles. Systematic review of all randomised clinical trials of adjuvant chemotherapy for gastric cancer compared with surgery alone, published before January 2000, were considered. Pooling of data was performed using the fixed effect model. Death for any cause was the study endpoint. The hazard ratio and its 95% confidence intervals (95% CI), derived according to the method of Parmar, were the statistics chosen for summarising the relative benefit of chemotherapy versus control. RESULTS Overall 20 articles (21 comparisons) were considered for analysis. Three studies used single agent chemotherapy, seven combination of 5-fluorouracil (5-FU) with anthracyclin, ten combination of 5-FU without anthracyclines. Information on 3658 patients, 2180 deaths, was collected. Chemotherapy reduced the risk of death by 18% (hazard ratio 0.82, 95% CI: 0.75-0.89, P < 0.001). Association of Anthracyclines to 5-FU did not show a statistically significant improvement when compared with the effect of the other regimens. CONCLUSIONS Chemotherapy produces a small survival benefit in patients with curatively resected gastric cancer. However, taking into account the limitations of literature based meta-analyses, adjuvant chemotherapy is still to be considered as an investigational approach.

Abstract
BACKGROUND There are indications that some features of gastric carcinoma are changing, with a possible impact on prognosis. The aim of this study was to examine any changes in type, location, stage, resection rate, postoperative mortality rate or prognosis for patients with gastric carcinoma in a well defined population. METHODS During 1974-1991, 1161 new cases of gastric adenocarcinoma were diagnosed in Ostergötland County, Sweden. Tumour location, Laurén histological type, tumour node metastasis (TNM) stage, radicality of tumour resection and postoperative complications were recorded after histological re-evaluation of tissue specimens and examination of all patient records. Dates of death were obtained from the Swedish Central Bureau of Statistics. Time trends were studied by comparing the intervals 1974-1982 (period 1) and 1983-1991 (period 2). RESULTS The proportion of diffuse type of adenocarcinoma increased (from 27 to 35 per cent), while that of mixed type decreased (from 16 to 9 per cent) and that of intestinal type was unchanged. The proportion of tumours located in the proximal two-thirds of the stomach increased (from 32 to 42 per cent) and the proportion of patients with tumours in TNM stage IV decreased (from 32 to 25 per cent). Overall tumour resection rates were unchanged, although the proportion of radical total gastrectomies increased (from 36 to 50 per cent). Excluding tumours of the cardia or gastric remnant after previous ulcer surgery, the 5-year relative survival rate after radical resection increased from 25 to 36 per cent and the postoperative mortality rate decreased for both radical (from 11 to 4 per cent) and palliative (from 18 to 6 per cent) resection. CONCLUSION The patterns of tumour histology, location and stage of gastric carcinoma have changed in the authors' region. These changes were paralleled by a significant improvement in survival and postoperative mortality rates.

Abstract
BACKGROUND Metastasis of gastric carcinoma to the brain is very uncommon. At The University of Texas M. D. Anderson Cancer Center (M. D. Anderson), less than 1% of patients with primary gastric carcinoma are found to have brain metastases. Little has been published regarding the evaluation and treatment of these patients. The purpose of this study was to review our experience with gastric cancer metastatic to the brain and to describe the efficacy of the treatment used. METHODS Between 1957 and 1997, a total of 218,690 patients were seen for evaluation of malignant tumors at M. D. Anderson. Of these patients, 3320 (1.5%) had a diagnosis of gastric cancer; however, only 24 patients (0.7%) were found to have brain metastases on imaging studies or at autopsy. We performed a retrospective review of these 24 patients and divided them into three groups on the basis of the treatment they received. RESULTS Group 1 included patients who received steroids alone (16 mg of dexamethasone, daily). Group 2 patients received 3000 cGy of whole-brain radiation therapy (WBRT) delivered in 10 fractions in addition to steroids. Group 3 patients were managed with surgical resection, WBRT, and steroids. There were 18 male and 6 female patients, with a median age of 53 years. The most common presenting symptoms were weakness, difficulty with balance, and headache. Of the 19 patients diagnosed antemortem, 11 patients developed neurological symptoms after the primary diagnosis of gastric carcinoma, whereas 8 patients developed neurological symptoms before the diagnosis of gastric cancer. Forty-five percent of patients had a single brain metastasis, whereas 55% had multiple lesions. All patients had systemic disease, with bone, liver, and lung involvement seen in 46%, 42%, and 29%, respectively. Nineteen of 24 patients received treatment after diagnosis of brain metastases. Four patients received steroids only (group 1), 11 patients received WBRT and steroids (group 2), and 4 patients were treated with surgery, WBRT, and steroids (group 3). Median survival was approximately 2 months for patients in groups 1 and 2, whereas group 3 patients had a median survival of slightly greater than I year. CONCLUSIONS Our results suggest that the overall prognosis of patients with brain metastases from gastric cancer is extremely poor (median survival, 9 weeks). WBRT, as an adjuvant to steroid treatment, was not effective in improving outcome in our series. In selected patients, most of whom were relatively young and had less advanced systemic disease, surgical resection followed by WBRT was associated with relatively long survival times (median survival, 54 weeks).

Abstract
PURPOSE The efficacy of adjuvant chemotherapy in gastric cancer is controversial. We conducted a phase III, randomized, multicentric clinical trial with the goal of assessing the efficacy of the combination of mitomycin plus tegafur in prolonging the disease-free survival and overall survival of patients with resected stage III gastric cancer. PATIENTS AND METHODS Patients with resected stage III gastric adenocarcinoma were randomly assigned, using sealed envelopes, to receive either chemotherapy or no further treatment. Chemotherapy was started within 28 days after surgery according to the following schedule: mitomycin 20 mg/m(2) intravenously (bolus) at day 1 of chemotherapy; 30 days later, oral tegafur at 400 mg bid daily for 3 months. Disease-free survival and overall survival were estimated using the Kaplan-Meier analysis and the Cox proportional hazards model. RESULTS Between January 1988 and September 1994, 148 patients from 10 hospitals in Catalonia, Spain, were included in the study. The median follow-up period was 37 months. The tolerability of the treatment was excellent. The overall survival and disease-free survival were higher in the group of patients treated with chemotherapy (P =.04 for survival and P =.01 for disease-free survival in the log-rank test). The overall 5-year survival rate and the 5-year disease-free survival rate were, respectively, 56% and 51% in the treatment group and 36% and 31% in the control group. CONCLUSION Our positive results are consistent with the results of recent studies; which conclude that there is a potential benefit from adjuvant chemotherapy in resected gastric cancer.

Abstract
BACKGROUND The prognosis for gastric cancer remains dismal; novel agents that target specific molecular pathways are needed as adjuvant therapy. Camptothecin (CPT), on inhibitor of topoisomerase I, is effective in the treatment of certain solid tumors; its effects on gastric cancer are largely undefined. The purpose of this study was to (1) characterize the effects of CPT on the growth of a human gastric cancer and (2) assess potential cellular mechanisms responsible for CPT-mediated growth inhibition. METHODS The human gastric cancer SIIA was transplanted subcutaneously into athymic nude mice. After tumors reached approximately 100 mm2, mice were randomized into 3 groups to receive either CPT (5 or 10 mg/kg) or vehicle (control) intraperitoneally 3 days per week for 3 weeks; tumor size was measured biweekly. To assess potential mechanisms of CPT-mediated inhibition, SIIA cells were treated with CPT (20 mumol/L) and cells were counted over a time course; apoptosis was assessed by Hoechst stain and DNA laddering. Expression of p53 (a tumor suppressor), p21Waf1 and p27Kip1 (cell cycle inhibitors), and Bcl-2 and Bcl-XL (antiapoptotic proteins) was determined. RESULTS CPT (5 and 10 mg/kg) significantly inhibited tumor growth of SIIA gastric cancers compared with controls. CPT-mediated inhibition of SIIA cell proliferation was associated with an increase in apoptosis. Moreover, CPT treatment resulted in induction of p53, p21Waf1, and p27Kip1 and a decrease in Bcl-2 and Bcl-XL RNA and protein levels. CONCLUSIONS Treatment with CPT effectively inhibited the growth of the human gastric cancer SIIA; the mechanism involved was induction of apoptosis mediated by up-regulation of p53, p21Waf1/Cip1, and p27Kip1 and the down-regulation of Bcl-2 and Bcl-XL. Novel agents such as CPT, which target specific molecular pathways, may prove clinically useful in the adjuvant treatment of gastric cancers.

Abstract
Gastric cancers are rarely diagnosed before the age of 40 years and the incidence reaches a peak during the 7th decade in the general population. A molecular mechanism of early tumor onset may be determined by comparing microsatellite instability (MSI), indicative of error-prone mismatch repair, and loss of heterozygosity (LOH) between gastric cancers in patients < or = 40 years of age and those of older ages. Three to 5 chromosomal loci, where MSI and/or LOH are commonly found in gastric cancers in the general population, were examined in formalin-fixed, paraffin-embedded samples from 102 patients < or = 40 years of age using a polymerase chain reaction-based non-radioactive screening method. MSI and/or LOH at a minimum of 1 locus were detected in 11/102 patients. The frequency of MSI and/or LOH at the D11S904 locus was significantly higher than that at the D2S119, D2S123, D5S409 and IFNA regions. No preferential genetic changes at the D11S904 locus were observed in elderly patients. Among several clinicopathological variables, a statistically significant association with MSI and/or LOH was observed only for tumors located at the cardia, compared with tumors at the antrum and the corpus. Our findings suggest that a unique mechanism may be involved in increasing the susceptibility of the D11S904 locus for either MSI or LOH, especially for cardia tumors in young patients. Early onset of gastric cancers in patients < or = 40 years of age is associated with genetic changes at preferential chromosomal loci, including D11S904.

Abstract
BACKGROUND The use of diagnostic techniques in the preoperative staging of patients with gastric cancer must be better defined. To further clarify which technique is indicated, we applied a new modality of computed tomography (CT) scanning for patients with gastric cancer. METHODS Dynamic CT of the abdomen using water as oral contrast agent was performed in 30 patients with gastric adenocarcinoma. Patients without evidence of metastatic disease underwent exploratory laparotomy and intraoperative staging. Resectable patients had surgical excision and definitive pathologic staging. RESULTS Two patients (7%) had metastatic disease by CT and were considered inoperable. The remaining 28 underwent laparotomy. Of these, six (21%) were unresectable and 22 (79%) had surgical resection. Dynamic CT adequately suggested advanced stage disease in four (67%) of the 6 unresectable patients. Wall thickness in dynamic CT correlated with the risk of serosal involvement (P < .001). Both CT and surgery had an accuracy of 64% (P > .05) in predicting pathologic staging. CT overstaged only 4% of cases. CONCLUSIONS Dynamic CT is a useful modality that can indicate inoperable disease, obviating the need for laparotomy in patients with gastric adenocarcinoma. CT can modify the surgical approach by suggesting unresectable or advanced disease. The low percentage of patients that are overstaged by CT, combined with its similar staging accuracy when compared with laparotomy, support its preoperative use in these patients.

Abstract
The aim of this trial was to investigate whether pre-operative chemotherapy leads to a 15% higher curative resectability rate in patients with operable gastric cancer. In this randomised trial, patients were allocated to receive either four courses of chemotherapy using 5-fluorouracil, doxorubicin and methotrexate (FAMTX) prior to surgery or to undergo surgery only. Patients younger than 75 years of age with a good physical and mental condition and a histologically proven adenocarcinoma of the stomach without clinical or radiographic (computed tomography scan) evidence of distant metastases were eligible for this trial. Early gastric cancer or cardia carcinoma were excluded. The response to chemotherapy was evaluated after two and four courses. In case of progressive disease (PD) after two courses, patients were operated upon as soon as possible. Otherwise complete response (CR) partial response (PR) or stable disease (SD), two more courses were scheduled. The standard surgical procedure was a limited lymphadenectomy (D1) with staging biopsy of the para-aortic lymph nodes. Between September 1993 and February 1996, 56 eligible and evaluable patients were entered: 27 were randomised to receive FAMTX before surgery and 29 to undergo surgery only. In the FAMTX + surgery treatment group, 15/27 (56%) had curative resections versus 18/29 (62%) in the surgery only arm. There was no difference in the frequency of TNM stages I + II in both treatment arms: 15/27 versus 15/29. Due to PD and/or toxicity, 12 patients (44%) could not complete the planned four courses of FAMTX. Response evaluation after chemotherapy was possible in 25 patients: 2 CR, 6 PR, 8 SD and 9 PD. The difference in curative resectability rate was 6.5% (95% confidence interval -32 to +19%) in favour of surgery only. Downstaging for stages I + II did not occur. PD was more often the reason for not completing the planned four courses than toxicity. More active regimens than FAMTX are required for future randomised trials.

Abstract
UNLABELLED Gastric carcinoma is the fourth commonest cause of death from malignant disease in United Kingdom. In the Western hemisphere, it usually presents with advanced disease, which contributes to its very poor prognosis. Pre-operative (neoadjuvant) chemotherapy offers the possibility of down-staging such tumours and the potential to render tumours operable. Computed tomography (CT) plays a central role in the assessment of patients presenting with the disease, and in those who undergo chemotherapy, in evaluating their response. OBJECTIVE This study was undertaken to evaluate the role of CT in predicting loco-regional spread of tumour following neoadjuvant chemotherapy in non-metastatic gastric and gastro-oesophageal cancers. METHODS AND MATERIALS We correlated CT evidence of loco-regional spread with pathological findings following surgery in 21 patients who received pre-operative chemotherapy. RESULTS Residual masses were seen on CT in 19 patients, and 15 contained active tumour, although in four patients no viable tumour was demonstrated at histopathology. The overall accuracy of CT in assessing loco-regional disease was disappointing with sensitivities, specificities, positive and negative predictive values of 57%, 43%, 75% and 33%, respectively. CONCLUSIONS We conclude that CT is not accurate in identifying residual loco-regional spread and therefore should not preclude surgery in those patients who have received neoadjuvant chemotherapy.

Abstract
The purpose of this study was to determine whether extended lymph node (D2) dissection is associated with a survival benefit for patients with histologically node-negative gastric cancer at a single institution in the United States. Review of the prospective gastric database at Memorial Sloan-Kettering Cancer Center from July 1985 to August 1995 identified 774 patients who had undergone curative gastric resection. Of these, 247 patients (32%) were identified with histologically negative lymph nodes by hematoxylin-eosin staining. Data are expressed as median (range). Overall survival was compared by log-rank test. The overall 5-year survival rate for the entire cohort was 79%. The extent of lymph node dissection did not predict survival over the entire cohort. However, when stratified for tumor (T) stage, D2 dissection offered a survival advantage for T3 tumors. The 5-year survival rate for patients with T3 tumors undergoing a D2 dissection (n = 15) was 54% compared to 39% for those undergoing a Dl dissection (n = 53, P <0. 05). D2 dissection is associated with improved survival in advanced T stage, node-negative gastric cancer. With adequate staging, results of gastric resection for adenocarcinoma in Western countries begin to approximate those seen in Japan. Excision of N2 lymph nodes may also remove microscopic metastatic disease, contributing to the survival benefit.

Abstract
BACKGROUND Our aim was to determine the frequency, survival and symptomatic local recurrence rate of patients with a positive proximal resection margin in a series of patients having a resection for carcinoma of the oesophagus or stomach. METHODS A retrospective study of pathology reports and case notes. Survival and data on local recurrence were obtained from the patient or general practitioner. RESULTS Ten (11.5%) of 87 patients having a gastric or oesophageal resection for carcinoma had a positive proximal resection margin. All 10 patients underwent a palliative resection for late-stage disease. Nine were dead at an average 8.3 months (range 2-20 months) post-resection and one patient remains alive at 9 months. Only one of these 10 patients had evidence of a local recurrence with recurrent dysphagia prior to death at 11 months. CONCLUSION A high incidence of a positive proximal resection margin was found. This occurred in patients who underwent a palliative resection for late-stage disease, most of whom died before local recurrence became a problem. For patients recognized as having late-stage disease, surgery for symptom palliation need not be aggressive (such as to include a thoracotomy) because achieving microscopic clearance is unlikely to affect the long-term outcome.

Abstract
The medical records of 31,808 patients with gastric cancer registered with the West-Midlands Cancer Registry between 1957-1981 were reviewed to determine the influence of age on presentation, stage assessment, management, survival and mortality rates. When analysed by stage, and excluding post-operative deaths, survival was similar in all age groups. This study confirms stage of disease to be the single most important prognostic factor. The inverse relationship between laparotomy and age implies inadequate assessment of stage in the elderly. The poor prognosis in unresected cases suggests that increased precise staging by laparotomy or laparoscopy will have minimal adverse effects. On the other hand this may result in increased resections and survival.

Abstract
The efficacy and toxicity of a combination of etoposide 100 mg/m2/day iv on day 2-4, leucovorin 300 mg/m2/day iv, and 5-FU 500 mg/m2 day iv on day 1-5 every 4 weeks were assessed in 21 patients with advanced gastric cancer with measurable or evaluable diseases. Eight patients had an objective response, including 3 in CR. The overall response rate was 38.1% (95% CI 33.4-42.8%). Five of 8 patients who exhibited locally advanced and unresectable diseases had an objective response (2 CR, 3 PR). The response rate in patients with metastatic disease was 23.0% (95% CI 14.4-31.6%). The median progression-free interval and overall survival time were 7 and 10 months, respectively. The most frequent side effect was alopecia (Gr I/II 71.4%). No treatment-related death occurred. Modified ELF is a relatively effective and tolerable combination regimen for advanced gastric cancer and can be safely administered to elderly patients and patients with systemic diseases.

Abstract
BACKGROUND & AIMS In contrast to the dramatic decrease in the overall incidence of gastric cancer, there has been a reported increase in the incidence of cases located in the gastric cardia. The aim of this study was to identify changes in site- and histology-specific incidence rates of gastric adenocarcinoma during a 50-year period. METHODS The Rochester Epidemiology Project medical records linkage system was used to identify all cases of gastric adenocarcinoma among residents of Olmsted County, Minnesota, between 1941 and 1990 (n = 342). Each patient's complete (inpatient and outpatient) medical records were reviewed and tumor location determined from pathological, surgical, endoscopic, and radiological reports. All available histological specimens (n = 246) were reviewed independently. RESULTS The overall incidence of gastric cancer decreased from 48.8 per 100,000 person-years in the 1940s to 11.6 per 100,000 in the 1980s, whereas the incidence of adenocarcinoma of the cardia did not change significantly during the 50-year period. The incidence of adenocarcinoma of the esophagogastric junction increased from 0.0 to 1.9 per 100,000 person-years, but the number of cases was small. CONCLUSIONS The incidence of adenocarcinoma of the gastric cardia has not increased in this population. The reported increase in cardia cancer in other populations may be due to an increasing incidence of adenocarcinoma of the esophagogastric junction.

Abstract
The effects of intragastric capsaicin and gastric artery ligation on the penetration of the gastric carcinogen N[methyl-3H]-N'-nitro-N-nitrosoguanidine ([3H]MNNG) to proliferative cells were studied in normal and healing rat gastric mucosa. The percentage of S-phase cells labeled with [3H]MNNG in normal corpus mucosa was higher (7.0 +/- 2.0%) after gastric artery ligation than in controls with intact blood flow (2.7 +/- 1.0%) and in animals treated with capsaicin (1.8 +/- 0.5%). Corpus mucosal blood flow was correlated with the percentage of S-phase cells labeled with [3H] MNNG in normal controls and in capsaicin-treated animals. In healing corpus mucosa and in the antrum, capsaicin or gastric artery ligation did not affect carcinogen penetration. We conclude that blood flow protects against penetration of carcinogens to proliferative cells in normal corpus mucosa but not in the antrum. Low mucosal blood flow in the corpus could be a risk factor for initiation of gastric carcinogenesis.

Abstract
A retrospective study of 954 resectable gastric cancers in a single institute of Taiwan from 1971 to 1990 was performed to evaluate improvements in gastric cancer surgery. The patients were divided into four time periods representing an overall experience of progressive implementation of aggressive resection and increased extent of systematic lymph node dissection. The clinicopathologic data and survival rates were statistically compared and the significance of the extent of resection on survival analyzed. A significant increase in the proportion of upper one-third tumors (from 14.8% to 20.4%) and a decrease in the incidence of intestinal type (73.6% to 41.5%) was found within the overall period. The proportion of patients with early gastric cancer increased from 11.5% to 19.4%. Patients who underwent total gastrectomy and combined visceral resection increased from 13.7% to 27.4% and 19.8% to 41.1%, respectively. An increase of both total dissected lymph node number and the incidence of detected lymph node metastases in early gastric cancer were associated with more extensive lymphadenectomy. An improved 5-year survival rate following aggressive resection was found for all stages except stage IV and T4 lesions, and the surgical mortality decreased from 5.5% to 2.0%. Patients with earlier stage lesions benefited more from radical resection, especially those with stage II and T2 lesions. Systematic lymph node dissection increased the 5-year survival of patients by about 10% for stage III or T3 lesions but not for patients with stage IV or T4 lesions. Multivariate analysis confirmed the significance of the improved technique of lymphadenectomy on the prognosis of gastric cancer following resection in Taiwan.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The results of 1281 potentially curative resections for advanced gastric cancer performed at the National Cancer Center Hospital between 1972 and 1986 were studied using a novel approach which circumvents the stage migration phenomenon. The incidence of metastasis and the 5-year survival rate of patients with positive nodes were calculated independently for each lymph node 'station', without any reference to overall pathological nodal stage. The therapeutic value of extended lymph node dissection was estimated by multiplication of incidence of metastasis and percentage 5-year survival rate of patients with metastasis for each station. The incidence of metastasis ranged from 2.4 per cent to 66 per cent and the 5-year survival rate of affected patients from 0 to 58.7 per cent in perigastric stations, depending on the site of the primary tumour. The incidence of metastasis was between 3.0 per cent and 44.4 per cent in the second tier of nodes (n2), and the 5-year survival rate ranged from 0 per cent to 47.5 per cent. The majority of second-tier stations showed evidence of benefit from node dissection.

Abstract
We have studied the expression of p53 in 206 patients with gastric adenocarcinomas. A standard immunohistochemical technique employing the CM-1 anti-p53 polyclonal antibody was applied to the routinely fixed and paraffin-embedded material from these tumours; overexpression of p53 was defined as positive nuclear staining: 46% (94/206) of gastric carcinomas expressed high levels of p53. There was no significant correlation between p53 positivity and the tumour grade, growth pattern, the Lauren type or lymph node metastases. Correlation with disease stage was only marginally significant (P = 0.05). Life table analysis revealed a highly significant association between p53 expression and survival (P = 0.0062), the odds ratio of death being 1.89 (95% confidence interval 1.33-2.69). The overall 5-year survival of patients with p53-positive tumours was 3% compared with 16% for those with p53-negative tumours (median survival time being 5.6 and 11.4 months respectively). These data suggest that overexpression of the p53 oncoprotein is an independent marker of shortened survival in gastric cancer patients.

Abstract
The lymphocytes and their subsets were determined in the peripheral blood of 62 gastric cancer patients and 68 controls using fluorescent conjugated monoclonal antibodies and flow cytometry (FACScan method). A significant increase in the total number of white blood cells from gastric cancer patients was noted in comparison to controls, but the percentage of lymphocytes was the same. The percentage of suppressor (cytotoxic) T cells (CD8) showed no difference in all stages of gastric cancer patients evaluated, but the percentage of helper (inducer) T cells (CD4) and the CD4/CD8 ratio decreased significantly in the advanced stages III and IV. Depression of the CD4/CD8 ratio was well correlated with tumor invasion, lymph node metastasis, and tumor size but not with sex, age, tumor location, gross type, or histologic differentiation. It appeared that the immune defect of gastric cancer patients was associated with the afferent arm (CD4) and worsened as the disease advanced. These results suggest that immunotherapy to stimulate the deficient immune system may play an important part in the multimodality treatment of patients with advanced gastric cancer.

Abstract
Since the peritoneal cavity is the most common site of initial recurrence in patients after surgery for gastric cancer, an intraperitoneal (IP) adjuvant treatment was tested in patients with resected gastric cancer with serosal involvement. Between March 1986 and September 1991, 44 consecutive patients with resected T3/T4-N0/N+ gastric cancer were given an IP combination, including cisplatin or carboplatin, etoposide, and alpha interferon-2b. The overall survival of these patients was compared with that observed in 47 historical controls (admitted to the same institutions from 1983 to 1986) with similar prognostic characteristics, who had not received adjuvant treatment after surgery. No major complication relating to the IP route was observed. Mild to moderate abdominal pain occurred in nine patients. Grade 3-4 myelotoxicity occurred in 14 patients. Interferon had to be reduced in five patients and suspended in one because of severe fatigue. Emesis occurred in 23/28 patients given cisplatin and 9/16 given carboplatin. At the time of this analysis (September 1992) median follow-up was 42 months (range 12-78) in the group receiving IP treatment, and 97 months (range 74-128) in the historical controls. There had been 20 deaths among treated patients compared with 36 in the control group. The 5-year estimated survival rate was significantly better in the patients who received IP adjuvant treatment (44% +/- 9 versus 23% +/- 6; P = 0.016). Using the Cox proportional hazard model with a backward procedure to correct for the influence of prognostic pretreatment variables, IP treatment again afforded a significant advantage in terms of survival (P = 0.04). Adjuvant IP immunochemotherapy appears to improve prognosis compared with historical controls in patients having operable gastric cancer with serosal infiltration.

Abstract
BACKGROUND Differing survival rates have been reported between patients having undergone surgical intervention for the treatment of gastric carcinoma in Japan and Western industrialized countries. Through the actual availability of the data compiled at a major Japanese medical center (National Cancer Center, Tokyo), it was possible, for the first time, to compare the patients and therapeutic results of a Japanese center (n = 1475) with that of a German center (Department of Surgery, Technical University of Munich, Munich; n = 453). METHODS The prognostic factors involving both groups were compared. Survival rates were analyzed in univariate and multivariate fashions. RESULTS Some of the examined prognostic factors, such as sex, histologic type, tumor size, and Borrmann classification, were similarly distributed. Differences in frequency were discovered concerning pathologic tumor (pT), node (pN), and metastasis (pM) categories, localization, and age groups. Univariate analysis showed a 2-year survival rate of 88% for all Japanese patients with gastric cancer compared with 58% for German patients. The 5-year survival rates were 77% and 44%, respectively. The difference in the 2-year and 5-year survival rates for both departments may be related to differences in frequencies of several characteristics. In performing the same analysis in a multivariate fashion for the patient populations at both centers, it became clear that an important prognostic factor was the center itself. The survival curves of patients from Tokyo and Munich with the same prognostic factors demonstrate this difference. These differences, however, were small in comparison with those of univariate analysis. CONCLUSIONS Using a similar classification of the tumor stage and similar prognostic characteristics, the prognosis for gastric cancer in Japan and Germany may be the same.

Abstract
The prognosis of patients with advanced gastric cancer who undergo curative resection is still unsatisfactory. The relationship between prognosis and various factors such as stage, lymph node metastasis, serosal invasion and regional lymph node reaction (follicular hyperplasia and sinus histiocytosis) was evaluated. Of the factors studied, the only one that correlated well with survival was sinus histiocytosis. Lymph node metastasis was related weakly to prognosis. No correlation between prognosis and stage, serosal invasion or follicular hyperplasia was observed. Sinus histiocytosis may represent the morphological tumour-host immune reaction. Lymph node metastases or histological types were not related to regional lymph node reaction. These results suggest that sinus histiocytosis could be a useful prognostic factor for gastric cancer. Intensive postoperative follow-up for recurrence may be necessary even for patients with low-grade sinus histiocytosis in whom curative surgery is attempted.

Abstract
At present, only radical surgical resection of gastric cancer offers a chance for cure. The objective of an operation for patients with disease that is confined locally is to maximize the potential for cure. The objective for patients with advanced incurable disease, obstruction, hemorrhage, and intractable pain is to provide the best palliation. The evaluation, staging, and surgical management of gastric cancer are described.

Abstract
In this review of English language publications from 1970, 5-year survival rates after surgery for gastric cancer have been analysed. While the proportion of patients coming to operation has fallen from 92 per cent before 1970 to 71 per cent by 1990, the proportion of operated patients undergoing resection has increased from 37 per cent before 1970 to 48 per cent before 1990. This change suggests improved preoperative staging leading to better patient selection for operation. The 5-year survival rate following all resections has increased significantly from 20.7 per cent before 1970 to 28.4 per cent before 1990, an increase of 7.7 per cent (95 per cent confidence interval 7.1-8.3 per cent). The 5-year survival rate following curative or radical resection has risen from 37.6 to 55.4 per cent over the same period, an increase of 17.8 per cent (95 per cent confidence interval 17.1-18.5 per cent). It is likely that this improvement has contributed to the decrease in the mortality rate from gastric cancer. Comparison of Japanese series with others suggests that diagnosis and treatment of the disease at an earlier stage will result in an even greater increase in 5-year survival rates outside Japan. Of the papers studied, 56 per cent were excluded from analysis, the majority because the data provided about 5-year survival rates were insufficient or the survival calculations inappropriate. Results of survival after operations for gastric cancer should be calculated and presented in a standardized manner.

Abstract
Although the incidence of carcinoma of the stomach has steadily declined over the last 50 years, approximately 23,000 new cases will be diagnosed in the United States this year and 13,700 patients will die. Despite marked improvement in operative techniques, fewer than 20 per cent of those diagnosed with gastric cancer beyond the most superficial levels of invasion will survive for over five years. Gastric tumours spread by local, lymphatic, and aggressive intra-peritoneal routes as well as hematogenous dissemination. Over 87 per cent of recurrences have local or regional components. Radiation therapy may decrease local and regional recurrences in those patients with transmural tumours. The neoadjuvant use of etoposide, adriamycin, and platinum may yield complete clinical and pathologic responses in patients found to have 'unresectable' tumours. Other chemotherapy regimens have been shown to have some effect on advanced disease and may have a role in the neoadjuvant setting. Our current recommendations for the treatment of gastric cancer in a controlled trial setting would be neoadjuvant chemotherapy followed by R2 resection, postoperative +/- intraoperative radiation therapy with the possibility of postoperative chemotherapy. Hopefully, this aggressive multimodality approach will significantly improve the five year survival for this disease.
