Impact of pCR after neoadjuvant chemotherapy and radical D2 dissection in locally advanced gastric cancers: Analysis of 1001 cases. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108343. [PMID: 38640606 DOI: 10.1016/j.ejso.2024.108343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Revised: 04/09/2024] [Accepted: 04/12/2024] [Indexed: 04/21/2024]
Abstract
BACKGROUND Advances in perioperative chemotherapy have improved outcomes in patients with gastric cancers (GC). This strategy leads to tumour downstaging and may result in a pathologic complete response (pCR). The study aimed to evaluate the predictors of pCR and determine the impact of pCR on long-term survival. METHODS At the Department of Gastrointestinal and HPB Oncology at the Tata Memorial Centre, Mumbai, 1001 consecutive patients with locally advanced GCs undergoing radical resection following neoadjuvant chemotherapy from January 2005 to June 2022 were included. RESULTS At a median follow-up of 61 months, the median OS was 53 months with a 5-year OS of 46.8 %. Ninety-five patients (9.49 %) realized pCR. Non-signet and well-differentiated histology were associated with pCR. pCR was significantly associated with improved OS, 5-year OS 79.2 % vs 43.2 % (HR 0.30, p < 0.001). On multivariable analysis, the realization of pCR and completion of adjuvant chemotherapy had superior OS. Whereas, signet-ring histology, linitis-like tumours, and high lymph node ratio had adverse outcomes. CONCLUSION Tumour grade and signet-ring histology predict achievement of pCR in locally advanced GCs after neoadjuvant chemotherapy. Patients with pCR have significantly improved survival. Future neoadjuvant strategies should focus on enhancing pCR rates to improve overall outcomes.

Abstract
Background Neoadjuvant chemotherapy is a standard of care for patients with adenocarcinoma of the esophagus and stomach in Europe, but still only 20–40 % respond to therapy and the critical issue; how to treat nonresponding patients is still unclear. So far, there is no randomized trial evaluating the impact of early termination of neoadjuvant chemotherapy and immediate tumor resection in nonresponding patients with locally advanced gastroesophageal cancer on postoperative outcome. With this exploratory pilot trial, we want to get first estimates about the effect of discontinuation of chemotherapy with the aim to plan and conduct a further definitive trial. Methods/design OPTITREAT is designed as a single-center, randomized controlled pilot trial with two parallel study groups. Four weeks after starting neoadjuvant chemotherapy in all patients, clinical response will be assessed by endoscopy and endosonographic ultrasound. Then, nonresponding patients (n = 84) will be randomized in a 1:1 ratio to intervention group with stopping chemotherapy and immediate tumor resection or control group with completion of chemotherapy before surgery. Outcome measures are overall survival, R0 resection rate, perioperative morbidity and mortality, histopathological response, and quality of life. Statistical analysis will be based on the intention-to-treat population. Due to the study design as an explorative pilot trial, no formal sample size calculation was performed. The planned total sample size of 120 patients is considered ethical and large enough to show the feasibility and safety of the concept. First data on differences between the study groups in the defined endpoints will also be generated. Discussion Individualized therapy is of utmost interest in the treatment of locally advanced gastroesophageal adenocarcinoma as less than half of the patients show objective response to current chemotherapy regimens. The findings of the OPTITREAT trial will help to get first data about clinical response evaluation followed by immediate tumor resection in nonresponding patients after 4 weeks of neoadjuvant chemotherapy. Based on the results of this pilot study, a future confirmatory trial will be planned to prove efficacy and evaluate significance.

Interim endoscopy results during neoadjuvant therapy for gastric cancer correlate with histopathological response and prognosis. Gastric Cancer 2015; 17:478-88.

Abstract
BACKGROUND Neoadjuvant chemotherapy for locally advanced gastric cancer leads to major histopathological response in less than 30 % of patients. Data on interim endoscopic response assessment do not exist. This exploratory prospective study evaluates early endoscopy after 50 % of the chemotherapy as predictor for later response and prognosis. METHODS Forty-seven consecutive patients were included (45 resected; 33 R0 resections). All patients received baseline endoscopy and CT scans, after 50 % of their chemotherapy (EGD-1, CT-1) and after completion of chemotherapy (EGD-2, CT-2). Interim endoscopic response (EGD-1) was assessed after having received 50 % (6 weeks) of the planned 12 weeks of neoadjuvant chemotherapy. Post-chemotherapy response was clinically assessed by a combination of CT scan (CT-2) and endoscopy (EGD-2). Histopathological response was determined by a standardized scoring system (Becker criteria). Endoscopic response was defined as a reduction of >75 % of the tumor mass. RESULTS Twelve patients were responders at EGD-1 and 13 at EGD-2. Nine patients (19.1 %) were clinical responders and 7 patients (15.6 %) were histopathological responders after chemotherapy. Specificity, accuracy, and negative predictive value of the interim EGD-1 for subsequent histopathological response were 31/38 (82 %), 36/47 (76 %), and 31/33 (93 %); and for recurrence or death, 28/30 (93.3 %), 38/47 (80.9 %), and 28/35 (80.0 %). Response at EGD-1 was significantly associated with histopathological response (p = 0.010), survival (p < 0.001), and recurrence-free survival (p = 0.009). CONCLUSIONS Interim endoscopy after 6 weeks predicts response and prognosis. Therefore, tailoring treatment according to interim endoscopic assessment could be feasible, but the findings of this study should be validated in a larger patient cohort.

Abstract
PURPOSE With improved chemotherapeutic regimens, metastasized gastric cancer may show a good response rendering an initially unresectable tumor resectable. We performed a retrospective analysis on the outcome of stage IV gastric cancer patients treated by chemotherapy followed by oncologic resection in a western institution. METHODS From August 1988 to December 2010, a total number of 1,817 patients underwent surgery for gastric cancer at the Department of Surgery, Technical University of Munich. A retrospective analysis of our prospective gastric cancer database identified 58 patients with stage IV gastric cancer having undergone induction chemotherapy followed by surgery in an individualized treatment concept. After induction chemotherapy usually consisting of 2 cycles of PLF (cisplatin, 5-fluorouracil, leucovorin), resection was performed with or without removal of metastases in patients without disease progression. Patients were followed up until death or loss to follow up. RESULTS The three most common metastatic locations were liver (27.6 %), distant lymph nodes (22.4 %), and peritoneum (19.0 %). Of patients, 13.8 % had metastases in more than one location. Thirty-day mortality was 5.2 %, 90-day mortality was 13.8 %, while overall postoperative morbidity accounted for 24 %. In 19 (32.8 %) patients, a complete resection without any macroscopic tumor residues was achieved. In 39 (67.2 %) patients, tumors could not be completely removed with either local residual disease or residual disease at distant sites. Overall median survival was 20 months, while patients without residual tumor survived significantly longer (72 months) than patients with residual disease (12 months, p = 0.001). CONCLUSION Secondary surgery of metastasized gastric cancer may be justified in selected cases without progression under induction chemotherapy. An achievable complete removal of the primary tumor and metastases appears the main selection criterion for patients benefitting from this approach.

A retrospective comparative exploratory study on two methylentetrahydrofolate reductase (MTHFR) polymorphisms in esophagogastric cancer: the A1298C MTHFR polymorphism is an independent prognostic factor only in neoadjuvantly treated gastric cancer patients. BMC Cancer 2014; 14:58. [PMID: 24490800 PMCID: PMC3922603 DOI: 10.1186/1471-2407-14-58] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2013] [Accepted: 11/26/2013] [Indexed: 12/16/2022] Open
Abstract
Background Methylentetrahydrofolate reductase (MTHFR) plays a major role in folate metabolism and consequently could be an important factor for the efficacy of a treatment with 5-fluorouracil. Our aim was to evaluate the prognostic and predictive value of two well characterized constitutional MTHFR gene polymorphisms for primarily resected and neoadjuvantly treated esophagogastric adenocarcinomas. Methods 569 patients from two centers were analyzed (gastric cancer: 218, carcinoma of the esophagogastric junction (AEG II, III): 208 and esophagus (AEG I): 143). 369 patients received neoadjuvant chemotherapy followed by surgery, 200 patients were resected without preoperative treatment. The MTHFR C677T and A1298C polymorphisms were determined in DNA from peripheral blood lymphozytes. Associations with prognosis, response and clinicopathological factors were analyzed retrospectively within a prospective database (chi-square, log-rank, cox regression). Results Only the MTHFR A1298C polymorphisms had prognostic relevance in neoadjuvantly treated patients but it was not a predictor for response to neoadjuvant chemotherapy. The AC genotype of the MTHFR A1298C polymorphisms was significantly associated with worse outcome (p = 0.02, HR 1.47 (1.06-2.04). If neoadjuvantly treated patients were analyzed based on their tumor localization, the AC genotype of the MTHFR A1298C polymorphisms was a significant negative prognostic factor in patients with gastric cancer according to UICC 6th edition (gastric cancer including AEG type II, III: HR 2.0, 95% CI 1.3-2.0, p = 0.001) and 7th edition (gastric cancer without AEG II, III: HR 2.8, 95% CI 1.5-5.7, p = 0.003), not for AEG I. For both definitions of gastric cancer the AC genotype was confirmed as an independent negative prognostic factor in cox regression analysis. In primarily resected patients neither the MTHFR A1298C nor the MTHFR C677T polymorphisms had prognostic impact. Conclusions The MTHFR A1298C polymorphisms was an independent prognostic factor in patients with neoadjuvantly treated gastric adenocarcinomas (according to both UICC 6th or 7th definitions for gastric cancer) but not in AEG I nor in primarily resected patients, which confirms the impact of this enzyme on chemotherapy associated outcome.

Abstract
BACKGROUND Recent data suggest primary resection as the preferable approach in patients with signet ring cell gastric cancer (SRC). The aim of our retrospective exploratory study was to evaluate the influence of SRC on prognosis and response in esophagogastric adenocarcinoma treated with neoadjuvant chemotherapy. METHODS A total of 723 locally advanced esophagogastric adenocarcinomas (cT3/4 N any) documented in a prospective database from two academic centers were classified according to the WHO definition for SRC (more than 50 % SRC) and analyzed for their association with response and prognosis after neoadjuvant treatment. RESULTS A total of 235 tumors (32.5 %) contained SRC. Median survival of SRC was 26.3 compared with 46.6 months (p < 0.001) for non-SRC. SRC were significantly associated with female gender, gastric localization, advanced ypT and R1/2 categories, and lower risk of surgical complications and anastomotic leakage (each p < 0.001). Clinical (21.1 vs. 33.7 %, p = 0.001) and histopathological response (less than 10 % residual tumor: 16.3 vs. 28.9 %, p < 0.001) were significantly less frequent in SRC. Clinical response (p = 0.003) and complete histopathological response (pCR) (3.4 %) (p = 0.003) were associated with improved prognosis in SRC. Clinical response, surgical complications, ypTN categories, but not SRC were independent prognostic factors in forward Cox regression analysis in R0 resected patients. Risk of peritoneal carcinomatosis was increased (p < 0.001), while local (p = 0.015) and distant metastases (p = 0.02) were less frequent than in non-SRC. CONCLUSIONS Prognosis of SRC is unfavorable. Although response to neoadjuvant chemotherapy is rare in SRC, it is associated with improved outcome. Thus, chemotherapy might not generally be abandoned in SRC. A stratification based on SRC should be included in clinical trials.

Factors predicting prognosis and recurrence in patients with esophago-gastric adenocarcinoma and histopathological response with less than 10 % residual tumor. Langenbecks Arch Surg 2012; 398:239-49.

Abstract
PURPOSE Neoadjuvant treatment is an accepted standard approach for treating locally advanced esophago-gastric adenocarcinomas. Despite a response of the primary tumor, a significant percentage dies from tumor recurrence. The aim of this retrospective exploratory study from two academic centers was to identify predictors of survival and recurrence in histopathologically responding patients. METHODS Two hundred thirty one patients with adenocarcinomas (esophagus: n = 185, stomach: n = 46, cT3/4, cN0/+, cM0) treated with preoperative chemotherapy (n = 212) or chemoradiotherapy (n = 19) followed by resection achieved a histopathological response (regression 1a: no residual tumor (n = 58), and regression 1b < 10 % residual tumor (n = 173)). RESULTS The estimated median overall survival was 92.4 months (5-year survival, 56.6 %) for all patients. For patients with regression 1a, median survival is not reached (5-year survival, 71.6 %) compared to patients with regression 1b with 75.3 months median (5-year survival, 52.2 %) (p = 0.031). Patients with a regression 1a had lymph node metastases in 19.0 versus 33.7 % in regression 1b. The ypT-category (p < 0.001), the M-category (p = 0.005), and the type of treatment (p = 0.04) were found to be independent prognostic factors in R0-resected patients. The recurrence rate was 31.7 % (n = 66) (local, 39.4 %; peritoneal carcinomatosis, 25.7 %; distant metastases, 50 %). Recurrence was predicted by female gender (p = 0.013), ypT-category (p = 0.007), and M-category (p = 0.003) in multivariate analysis. CONCLUSION Response of the primary tumor does not guarantee recurrence-free long-term survival, but histopathological complete responders have better prognosis compared to partial responders. Established prognostic factors strongly influence the outcome, which could, in the future, be used for stratification of adjuvant treatment approaches. Increasing the rate of histopathological complete responders is a valid endpoint for future clinical trials investigating new drugs.

Abstract
BACKGROUND Response to neoadjuvant chemotherapy is an independent prognostic factor in locally advanced gastric cancer. However, no prospectively tested pretherapeutic parameters predicting response and/or survival in gastric cancer are available in clinical routine. METHODS We evaluated the prognostic significance of various clinical pathologic parameters in 410 patients who were treated with neoadjuvant chemotherapy followed by gastrectomy. Clinical and histopathologic response evaluation was performed by using standardized criteria. A prognostic score was created on the basis of the variables identified in the multivariate analysis. RESULTS Three pretherapeutic parameters were identified as positive predictive factors for response and prognosis: tumor localization in the middle third of the stomach (P=0.001), well-differentiated tumors (P=0.001), and intestinal tumor type according to Laurén classification (P=0.03). A prognostic index was constructed, dividing the patients into three risk groups: low (n=73), intermediate (n=274), and high (n=63). The three groups had significantly different clinical (P=0.007) and histopathologic response rates (P=0.001) and survival times, with a median survival time that was not reached in the low-risk group, 39.2 months in the intermediate-risk group, and 20.5 months in the high-risk group. The corresponding 5-year survival rates were 65.3, 41.2, and 21.2% (P<0.001), respectively. CONCLUSIONS A simple scoring system based on three clinicopathologic parameters accurately predicts response and prognosis in neoadjuvant treated gastric cancer. This system provides additional useful information that could be applied to select gastric cancer patients pretherapeutically for different treatment approaches. Prospective testing of the score in an independent patient cohort is warranted.

Abstract
INTRODUCTION Response to neoadjuvant chemotherapy (NAC) is an independent prognostic factor in locally advanced gastric cancer. However, no prospectively tested pretherapeutic parameters predicting response and/or survival in gastric cancer are available in clinical routine. PATIENTS AND METHODS We evaluated the prognostic significance of various clinicopathologic parameters in 410 patients who were treated with NAC followed by gastrectomy. Clinical and histopathological response evaluation was performed using standardized criteria. A prognostic score was created on the basis of the variables identified in the multivariate analysis. RESULTS Multivariate analysis identified three pretherapeutic parameters as positive predictive factors for response and prognosis: tumor localization in the middle third of the stomach (p = 0.001), well differentiated tumors (p = 0.001) and intestinal tumor type according to Laurén's classification (p = 0.03). From the obtained data a prognostic index was constructed, dividing the patients into three risk groups: low (n = 73), intermediate (n = 274), and poor (n = 63). The three groups had significantly different clinical (p = 0.007) and histopathological response rates (p = 0.001) and survival times, with a median survival time that was not reached in the low-risk group, 39.2 months in the intermediate-risk group and 20.5 months in the poor-risk group. The corresponding 5-year survival rates were 65.3, 41.2, and 21.2 % (p < 0.001), respectively. CONCLUSION A simple scoring system based on three clinicopathologic parameters, accurately predicts response and prognosis in neoadjuvant treated gastric cancer. This system provides additional useful information that could be applied to select gastric cancer patients pretherapeutically for different treatment approaches. Prospective testing of the score in an independent patient cohort is warranted.

Abstract
BACKGROUND Although the role of peri-operative chemotherapy is established in the treatment of locally advanced gastric cancer, the optimal regime remains to be determined. FOLFOX has been used in palliative setting with good response rates but its role in a neoadjuvant setting is not well established. METHODS This is a prospective non-randomized study comparing peri-operative FOLFOX versus adjuvant FOLFOX in patients with resectable locally advanced gastric cancer. Response to chemotherapy was assessed according to WHO criteria and pathological changes. Kaplan-Meier log rank test was used to calculate and compare survival differences. RESULTS There were 73 patients (neoadjuvant = 36). Complete and partial response was observed in 2 (6%) and 21 (64%) patients, respectively. Four-year overall survival (OS) in the neoadjuvant arm was 78% versus 51% in the adjuvant arm (P = 0.031). Subgroup analysis found R0 resection (86% vs. 55%, P = 0.011) and patients with proximal cancers (87% vs. 14%, P < 0.001) to have improved OS. The most common side effect was grade 1-2 leukopenia. There were no grade 3 neuropathies, grade 4 cytopaenias, or treatment related deaths. CONCLUSION Peri-operative treatment with FOLFOX shows promise in patients with resectable locally advanced gastric cancer. It warrants further evaluation and should be considered an alternative to peri-operative ECF.

Abstract
BACKGROUND This study assessed the postoperative morbidity and mortality occurring in the first 30 days after radical gastrectomy by comparing gastric cancer patients who did or did not receive the FOLFOX7 regimen of neoadjuvant chemotherapy. METHODS We completed a retrospective analysis of 377 patients after their radical gastrectomies were performed in our department between 2005 and 2009. Two groups of patients were studied: the SURG group received surgical treatment immediately after diagnosis; the NACT underwent surgery after 2-6 cycles of neoadjuvant chemotherapy. RESULTS There were 267 patients in the SURG group and 110 patients in the NACT group. The NACT group had more proximal tumours (P = 0.000), more total/proximal gastrectomies (P = 0.000) and longer operative time (P = 0.005) than the SURG group. Morbidity was 10.0% in the NACT patients and 17.2% in the SURG patients (P = 0.075). There were two cases of postoperative death, both in the SURG group (P = 1.000). No changes in complications or mortality rate were observed between the SURG and NACT groups. CONCLUSION The FOLFOX7 neoadjuvant chemotherapy is not associated with increased postoperative morbidity, indicating that the FOLFOX7 neoadjuvant chemotherapy is a safe choice for the treatment of local advanced gastric cancer.

Abstract
INTRODUÇÃO: Embora decrescendo nos países do chamado primeiro mundo, o adenocarcinoma gástrico mantém-se como terceiro tumor mais frequente no sexo masculino mundialmente. Sua mortalidade é muito elevada, fruto do diagnóstico tardio em lesões muito avançadas, o que frequentemente torna paliativo seu tratamento, motivos pelos quais se justificam estudos no sentido de melhorar estes resultados. MÉTODO: Revisão da literatura através do portal de periódicos da CAPES indicados por busca no sites da Bireme e PubMed. Além disso, foram consultados os sumários do 8º Congresso Internacional de Câncer Gástrico em 2009. Foi apresentada uma sugestão de algoritmo de atendimento destes pacientes. CONCLUSÕES: O surgimento de novas drogas anticancer, mais efetivas, está propiciando novas alternativas para a ressecção gástrica como tratamento paliativo. Novos protocolos estão surgindo mostrando boas perspectivas para melhorar os resultados desta doença.

Abstract
BACKGROUND Treatment of gastric cancer is more and more becoming an individualized decision. The choice of the optimal approach is based on prognostic factors, on the anatomic site of the tumor, and on expectations about the response to neoadjuvant treatment. Early gastric cancer that is limited to the mucosal layer is the domain of endoscopic resections. As soon as the submucosal layer is invaded, surgical strategies with adequate lymphadenectomy become necessary. DISCUSSION In many East Asian Centers and some other centers in the world, these tumors are resected by a laparoscopic approach. With a high experience, this can be done with excellent quality and outcome. In locally advanced gastric cancer, multimodal treatment can improve survival in comparison to surgery alone. However, the strategies differ significantly around the world. While adjuvant chemoradiotherapy is standard in the USA, in Europe, perioperative chemotherapy is the first choice, and in Japan, adjuvant chemotherapy is recommended. In Europe, three randomized phase III studies on the value of preoperative chemotherapy have been performed. Two of them have shown that perioperative chemotherapy does significantly improve the survival of patients with adenocarcinoma of the stomach and of the esophagogastric junction. The one including only preoperative chemotherapy failed to show a survival benefit for the combined treatment arm but showed excellent outcomes in both the surgery alone and the preoperative chemotherapy arms. Based on these studies, patients with stage II or stage III disease are now treated with perioperative chemotherapy. Additionally, it is generally accepted for more than 10 years now that responding patients have a significantly improved prognosis compared to nonresponding patients. The percentage of responding patients varies depending on the applied regimen between 20% and 45%. Therefore, early response evaluation or response prediction is an utmost important field of research. Proximal tumors are treated with a transhiatal extended gastrectomy, tumors in the middle third with a total gastrectomy, and distal tumors with a subtotal gastrectomy, if possible. Modified D2 lymphadenectomy avoiding splenectomy is now accepted as the standard procedure, providing improved prognosis for certain subgroups of patients. Individualized resection and lymphadenectomy techniques for early tumor stages and response-based neoadjuvant concepts for locally advanced tumors are the challenge for the future.

Abstract
PURPOSE Patients with locally advanced gastric cancer benefit from combined pre- and postoperative chemotherapy, although fewer than 50% could receive postoperative chemotherapy. We examined the value of purely preoperative chemotherapy in a phase III trial with strict preoperative staging and surgical resection guidelines. PATIENTS AND METHODS Patients with locally advanced adenocarcinoma of the stomach or esophagogastric junction (AEG II and III) were randomly assigned to preoperative chemotherapy followed by surgery or to surgery alone. To detect with 80% power an improvement in median survival from 17 months with surgery alone to 24 months with neoadjuvant, 282 events were required. RESULTS This trial was stopped for poor accrual after 144 patients were randomly assigned (72:72); 52.8% patients had tumors located in the proximal third of the stomach, including AEG type II and III. The International Union Against Cancer R0 resection rate was 81.9% after neoadjuvant chemotherapy as compared with 66.7% with surgery alone (P = .036). The surgery-only group had more lymph node metastases than the neoadjuvant group (76.5% v 61.4%; P = .018). Postoperative complications were more frequent in the neoadjuvant arm (27.1% v 16.2%; P = .09). After a median follow-up of 4.4 years and 67 deaths, a survival benefit could not be shown (hazard ratio, 0.84; 95% CI, 0.52 to 1.35; P = .466). CONCLUSION This trial showed a significantly increased R0 resection rate but failed to demonstrate a survival benefit. Possible explanations are low statistical power, a high rate of proximal gastric cancer including AEG and/or a better outcome than expected after radical surgery alone due to the high quality of surgery with resections of regional lymph nodes outside the perigastic area (celiac trunc, hepatic ligament, lymph node at a. lienalis; D2).

Abstract
Recent studies have shown an association between the GNAS1 T393C polymorphism and clinical outcome for various solid tumors. In this study, we genotyped 51 patients from an observational trial on cisplatin/5-FU-based neoadjuvant radiochemotherapy of locally advanced esophageal cancer (cT2-4, Nx, M0) and genotyping was correlated with histomorphological tumor regression. The C-allele frequency in esophageal cancer patients was 0.49. Pearson's chi(2)-test showed a significant (P<0.05) association between tumor regression grades and T393C genotypes. Overall, 63% of the patients in the T-allele group (TT+CT) were minor responders with more than 10% residual vital tumor cells in resection specimens, whereas T(-) genotypes (CC) showed a major histopathological response with less than 10% residual vital tumor cells in 80%. The results support the role of the T393C polymorphism as a predictive molecular marker for tumor response to cisplatin/5-FU-based radiochemotherapy in esophageal cancer.

Abstract
Despite the recent decline in the incidence of gastric cancer in North America and Western Europe, treatment remains a challenging problem for oncologists. Surgery is the primary modality for managing early-stage disease, but most patients who undergo a curative resection develop locoregional or distant recurrence. Consequently, there has been great interest in evaluating strategies to prevent recurrences and improve overall mortality. This article is a review of data on adjuvant and neoadjuvant treatment approaches for gastric cancer, including radiotherapy, chemotherapy, and chemoradiotherapy. Compared with surgery alone, the North American Intergroup 0116 trial demonstrated a clear survival benefit with the administration of a postoperative regimen of 5-fluorouracil, leucovorin, and external beam radiation therapy, and these findings have made concurrent chemoradiation a standard of care in patients with resected gastric cancer. More recently, the British Medical Research Council Adjuvant Gastric Cancer Infusional Chemotherapy (MAGIC) study found that preoperative and postoperative administration of epirubicin, cisplatin, and 5-fluorouracil significantly improved survival beyond surgery alone. Thus, after decades of negative studies, 2 successful strategies in localized gastric cancer are now available. Ongoing and proposed trials include the current Intergroup study (Cancer and Leukemia Group B 80101), which is assessing the role of a potentially more active postoperative chemoradiation regimen. The proposed MAGIC-B study will examine the role of adding bevacizumab to perioperative chemotherapy, and the planned CRITICS study by the Dutch Gastric Cancer Group will evaluate the role of postoperative chemoradiation in combination with preoperative chemotherapy.

Abstract
Although gastric cancer is still a worldwide major public health concern, it remains relatively uncommon in the Western countries. Despite improvement in surgical morbidity and mortality, as well as significant advancement of chemotherapy and radiotherapy options, the survival for gastric cancer has not significantly improved over the past decades. In the United States, standard of care for localized resectable gastric cancer is with adjuvant chemoradiotherapy. In this article, we summarize salient randomized and phase II and III clinical trials representing current treatment for gastric cancer.

Abstract
Despite a decline in its incidence in the Western world, gastric cancer (GC) remains the fourth most frequent cancer diagnosis worldwide and is, after lung cancer, the second leading cause of death from a malignant disease globally. Based on the published literature, treatment guidelines and reports from international meetings, we here review the current treatment options for GC and discuss insights and perspectives from the latest clinical studies. The management of GC in the early stages of the disease is based on an optimal surgical resection of the primary tumor and the regional lymph nodes. However, less than one third of patients have a resectable disease at diagnosis and among those operated, more than half are not cured by surgery alone, due to a high rate of relapse. Thus, for the majority of patients, systemic cytotoxic therapy, and sometimes radiotherapy, is a treatment option both as an adjunct to surgery and in the palliative setting. Adjuvant chemotherapy offers only a marginal benefit and has not become a standard of care in the West. In North America, adjuvant chemoradiation is broadly used, shown to significantly improve overall survival, albeit with the cost of high toxicity. Furthermore, a recently reported study from the United Kingdom demonstrated a significant disease-free and survival benefit by the use of perioperative combination chemotherapy. Several chemotherapeutic agents have been tested as a palliative therapy in advanced GC including 5- fluorouracil (5-FU), oral pyrimidines, platinum derivatives, anthracyclines, taxanes and camptothecans. It is now accepted that chemotherapy is better than best supportive care only and that 5-FU based combinations are more effective than monotherapy. However, the response rates have generally been moderate and there is no consensus on the optimal combination of cytotoxic agents and the potential role of more recently developed "targeted therapies".

Abstract
PURPOSE The objective of this study was to analyze the hypermethylation of tumor-related gene promoters for an association with therapy response and clinicopathologic features of neoadjuvant-treated gastric cancer patients. Furthermore, we analyzed the relationship of promoter hypermethylation with microsatellite instability and loss of heterozygosity (LOH) of the tumors. EXPERIMENTAL DESIGN Pretherapeutic biopsies of 61 patients, subsequently treated with cisplatin and 5-fluorouracil, were studied. Methylation analysis of six gene promoters was done using MethyLight technology. Microsatellite analysis was mainly done in previous studies. RESULTS The methylation frequencies for the analyzed genes were MGMT, 44%; LOX, 53%; p16, 46%, E-cadherin, 30%; 14-3-3sigma, 69%; and HPP1, 82%. Concordant methylation of more than three genes was found in 46% of the tumors and was inversely correlated with the LOH rate (P = 9 x 10(-5)) and associated with female gender (P = 0.049), nonintestinal type tumors (P = 0.04), and a nonproximal tumor location (P = 0.003). No statistically significant association between the methylation of a single gene or the concordant methylation of multiple genes was found with response or survival. However, patients with none or only one methylated gene showed a trend for an increase in survival (5-year survival rate, 83% versus 35%; P = 0.067). CONCLUSION The highly significant inverse correlation of promoter methylation and LOH rate reflects major alternative molecular pathways in gastric carcinogenesis. Methylation was not statistically significantly associated with the response to cisplatin/5-fluorouracil-based therapy. However, a concordant methylation of more than three genes defines subgroups of gastric cancer with distinct biological and genetic characteristics.

Abstract
BACKGROUND Staging laparoscopy has been shown to be useful for increasing the accuracy of preoperative staging. However, controversy still exists regarding patient selection and subsequent treatment. The aim of this study was to determine the role of staging laparoscopy for a group that has a policy to perform aggressive surgery for advanced gastric cancer. METHODS Twenty-four patients with clinical T3 or T4 gastric cancer expected to undergo curative resection, based on conventional preoperative diagnostic methods underwent staging laparoscopy. We examined the accuracy and the impact of staging laparoscopy on the further treatment options. RESULTS The mean running time for the staging laparoscopy was 40.7 min (range: 25-75 min), and one complication was noted (4.2%). In regard to the tumor depth, 11 of 24 (45.8%) cases had a discrepancy after staging laparoscopy. In addition, 15 of 24 patients (62.5%) were found to have unsuspected peritoneal metastases, and 8 patients (33.3%) were excluded from laparotomy. The remaining 16 patients (66.7%), including 9 patients with localized peritoneal metastases (P1), underwent resection. The diagnostic accuracy for T factor was 81.3% in 16 laparotomy cases and overall accuracy of P factor was 91.7%. CONCLUSIONS Staging laparoscopy had a significant impact on decisions regarding the treatment plan in patients with advanced gastric cancer for a group that has an aggressive treatment strategy.

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
PURPOSE High expression of cyclooxygenase-2 (COX-2) was shown to inhibit chemotherapy- and radiotherapy-induced apoptosis. We analyzed the association of COX-2 mRNA and protein expression with histomorphologic response to neoadjuvant radiochemotherapy in esophageal cancer. EXPERIMENTAL DESIGN Fifty-two patients with resectable esophageal cancers (cT2-4, Nx, and M0) received neoadjuvant radiochemotherapy (cisplatin, 5-5-fluorouracil, 36 Gy) followed by transthoracic en bloc esophagectomy. Histomorphologic regression was defined as major response when resected specimens contained less than 10% of residual vital tumor cells. RNA was isolated from endoscopic biopsies (paired tumor and normal tissue) before neoadjuvant treatment and quantitative real-time reverse transcriptase-PCR (Taqman) assays were done to determine COX-2 mRNA expression levels standardized for beta-actin. COX-2 protein expression in pretreatment biopsies and post-therapeutic resection specimens was analyzed by immunostaining of tumor cells. RESULTS Median COX-2 mRNA expression levels were significantly (P < 0.0001) different between paired tumor (median, 2.2) and normal tissues (median, 0.159). Comparison of pre-therapeutic and posttherapeutic specimens showed a significant difference (P < 0.006) in COX-2 protein expression. Twelve of 52 tumors showed down-regulation and 3 of 52 showed up-regulation of COX-2 protein expression during neoadjuvant radiochemotherapy. High COX-2 protein expression in post-therapeutic resection specimens was significantly associated with minor histopathologic response (P < 0.04) and poor prognosis (5-year survival probabilities: 26.3 +/- 8.2% for minor and 58.6% +/- 12.9% for major histopathologic response; P < 0.01). CONCLUSION High COX-2 protein expression following neoadjuvant radiochemotherapy in resection specimens is significantly associated with minor histopathologic response to neoadjuvant therapy and very poor prognosis.

Abstract
Although the incidence of gastric cancer is decreasing, it remains a significant source of cancer-related mortality. Surgery remains the best chance for cure from gastric cancer. Adjuvant and neoadjuvant therapy have played increasing roles in attempting to reduce the disease-specific mortality and prolong survival. In this article, the authors review the literature and summarize the salient points regarding the roles of adjuvant and neoadjuvant therapy for gastric cancer.

Abstract
BACKGROUND AND OBJECTIVES Neoadjuvant chemotherapy is increasingly considered an effective treatment option for patients with gastric carcinoma. Aim of the study is to evaluate the prognostic significance of the pathological response and of known prognostic factors in a group of accurately staged locally advanced gastric cancer (LAGC) patients. METHODS Thirty-three patients with LAGC, staged by laparoscopy, underwent D2-gastrectomy after preoperative chemotherapy. Survival was calculated by Kaplan-Meier method and differences were assessed by the Log-rank and Breslow test. Multivariate analysis was performed using the Cox proportional hazard model in backward stepwise regression. RESULTS Curative resection (R0) was achieved in 81.8% of patients. A complete or subtotal pathological response was documented in 3 and 6%, respectively. Nineteen out of thirty-three (57.6%) patients were alive and 16 of them were free of relapse at last follow-up. Survival rates were 81, 67, and 59% at 12, 24, and 36 months, respectively. At univariate and multivariate analysis, only R0 resection was found to be an independent prognostic factor. CONCLUSIONS In the current study, R0 resection is the most important prognostic factor for resectable LAGC; according to our results we feel encouraged to consider neoadjuvant chemotherapy a promising modality for increasing the R0-percentage of gastric carcinoma patients who could benefit from a curative surgery.

Abstract
PURPOSE The excision repair cross-complementing 1 (ERCC1) gene is coding for a nucleotide excision repair protein involved in the repair of radiation- and chemotherapy-induced DNA damage. We examined the potential of quantitative ERCC1 mRNA expression to predict minor or major histopathological response to neoadjuvant radiochemotherapy (cisplatin, 5-fluorouracil, and 36 Gy of radiation) followed by transthoracic en bloc esophagectomy in patients with locally advanced esophageal cancer (cT(2-4), N(x), M(0)). EXPERIMENTAL DESIGN Tissue samples were collected by endoscopic biopsy before treatment. RNA was isolated from biopsies, and quantitative real-time reverse transcriptase PCR assays were performed to determine ERCC1 mRNA expression. Relative mRNA levels (tumor/normal ratios) were calculated as (ERCC1/beta-actin in tumor)/(ERCC1/beta-actin in paired normal tissue). ERCC1 expression levels were correlated with the objective histopathological response in resected specimens. Histomorphological regression was defined as major response when resected specimens contained <10% of residual vital tumor cells or in case a pathologically complete response was achieved. RESULTS Twelve of 36 tumors showed a major histopathological response, and 24 of 36 showed a minor histopathological response. Relative expression levels of ERCC1 of >1.09 were not associated with a major histopathological response (sensitivity, 62.5%; specificity, 100%) and 15 of 24 patients with minor histopathological response to the delivered neoadjuvant radiochemotherapy could be unequivocally identified. This association of dichotomized relative ERCC1 mRNA expression and histopathological response was statistically significant (P < 0.001). CONCLUSIONS Relative expression levels of ERCC1 mRNA determined by quantitative real-time reverse transcriptase-PCR appear highly specific to predict minor response to our neoadjuvant radiochemotherapy protocol in patients with locally advanced esophageal cancer and could be applied to prevent expensive, noneffective, and potentially harmful therapies in a substantial number (42%) of patients.

Abstract
Gastric cancer has a poor prognosis. It is often diagnosed at an advanced stage, and potentially curative treatments often can not be exercised. Even when a curative surgical resection is possible, only a minority of patients survive beyond 5 years, and locoregional failures are frequent among patients undergoing curative resections. Recently, the use of postoperative adjuvant chemoradiotherapy has yielded some notable benefits. Earlier studies have shown survival benefits in patients undergoing chemoradiotherapy for locally advanced unresectable gastric cancer. The recently reported Intergroup 0116 trial compared surgery alone with surgery plus postoperative chemotherapy plus chemoradiotherapy. Superior overall and disease-free survival rates among patients given combined-modality postoperative therapy were observed. These results established a new standard of care for patients following resection of gastric carcinoma. Preoperative combined-modality chemoradiotherapy may improve resectability, and is under investigation at the University of Texas M. D. Anderson Cancer Center. The development of novel radioenhancers and the selection of therapy on the basis of molecular determinants of response may result in much-needed advances in this field.

Abstract
Potential benefits of neoadjuvant therapy for locally advanced gastric cancer include tumor downstaging and an increased R0 resection rate. Potential disadvantages include increased surgical complications. This study assesses postoperative morbidity and mortality by comparing patients undergoing gastrectomy with and without neoadjuvant chemotherapy. From October 1998 to July 2002, a total of 34 patients with locally advanced gastric cancer were placed on a phase II neoadjuvant chemotherapy protocol consisting of two cycles of CPT-11 (75 mg/m(2)) with cisplatin (25 mg/m(2)). Demographic, clinical, morbidity, and mortality data were compared for these patients (CHEMO) versus 85 patients undergoing gastrectomy without neoadjuvant chemotherapy (SURG). The CHEMO patients were more likely to be less than 70 years of age (P< or =0.01), have proximal tumors (P< or =0.01), and undergo proximal gastrectomy (P< or =0.025). Fifty-two percent of SURG patients had T3/T4 tumors compared to 19% of CHEMO patients, consistent with tumor downstaging. The R0 resection rate was similar (80%). Morbidity was 41% in CHEMO patients and 39% in SURG patients. There were five postoperative deaths (4.4%), two in the CHEMO group and three in the SURG group (P=NS). It was concluded that neoadjuvant chemotherapy with CPT-11 and cisplatin is not associated with increased postoperative morbidity compared to surgery alone. CPT-11-based neoadjuvant chemotherapy should be tested further in combined-modality treatment of gastric cancer.

Abstract
The present multimodal treatment approach was designed to achieve prolonged tumor control in advanced gastric cancer. A total of 26 patients with stage IV gastric cancer (metastatic disease n=25), ECOG performance status 0-3 and laparoscopically evaluated peritoneal status received a modified EAP schedule to prove chemosensitivity and to mobilize autologous peripheral blood stem cells (aPBSC). Patients without progressive disease proceeded to tandem high-dose chemotherapy (HD-CT) and aPBSCT. Patients with >50% reduction of the target lesion received a second cycle of HD-CT. Responders were selected for local R0 resections (D2 resection) according clinical criteria. Of 26 patients, 20(77%) achieved partial remission after dose-intensive chemotherapy: local R0 resection was achieved in 12 out of 14 patients selected for surgery (46% of all patients). Eight of these R0-resected patients initially had peritoneal carcinomatosis. With a median follow-up of 3.2 years, four patients are still alive. The median overall survival was 8.4 months (CI 2.5-14.4 months), for histologic regression grade 3 (seven out of 25 patients, 28%) 29 months (CI 12-46 months). The combined treatment approach is tolerable and feasible in advanced disease and opens a therapeutic window for a significant proportion of patients, even in cases with histologically proven peritoneal carcinomatosis.

Abstract
UNLABELLED The five years survival rate for patients with gastric cancer is 15-25%. With the aim of improving survival, chemotherapy has been used in different adjuvant settings. Similarly, but with the aim of improving quality of life and prolonging life, chemotherapy has been used extensively in metastatic disease. In this review we have included studies of systemic and intraperitoneal chemotherapy given before, during or after operation and for advanced disease. A meta-analysis has been made on the 21 randomised studies that used adjuvant systemic chemotherapy postoperatively. A significant survival benefit for the patients treated postoperatively compared with controls was identified (odds ratio (OR) 0.84, 95% confidence interval (CI) 0.74 to 0.96). When western and Asian studies were analysed separately we found no survival benefit for the treated patients in the western groups (OR 0.96 (95 CI 0.83 to 1.12)). Flaws in the conduct of several trials made it difficult to draw firm conclusions, including the exclusion of a small but clinically meaningful survival benefit. Preoperative or neoadjuvant chemotherapy has shown effects in some patients, but no significant benefit was found in the few randomised studies. The few studies that reported intraperitoneal therapy showed no detectable survival benefit either. In patients with advanced disease, four small randomised studies found significantly longer survival in the treated patients. The survival benefit is in the range of 3-9 months, and there were also improvements of the quality of life. Several drug combinations have been tested, however, with no confirmed superiority for a particular regimen. CONCLUSIONS Adjuvant chemotherapy cannot be recommended as a routine because of the lack of confirmed beneficial effects. Some patients with advanced disease will have a clinically important benefit from palliative chemotherapy, so this can be recommended for patients who are otherwise in good health.

Abstract
PURPOSE Neoadjuvant chemotherapy in locally advanced gastric cancer is effective, but is often associated with severe side effects, including fatal outcome. This study evaluates a combination of cisplatin, folinic acid and 5-fluorouracil (PLF) in terms of efficacy (R-0 resection rate) and toxicity. METHODS Twenty-five patients with locally advanced gastric cancer who after extensive staging were deemed not suitable for curative resection underwent neoadjuvant chemotherapy. Three or four cycles of cisplatin (50 mg/m(2) days 1 and 15), folinic acid (200 mg/m(2) days 1, 8, 15 and 22), and 5-fluorouracil (2,000 mg/m(2 ) days 1, 8, 15 and 22) were administered. Cases with progressive disease were taken off the study. Two weeks after finishing chemotherapy resection was performed and all patients were enrolled in a structured follow-up. RESULTS Of the patients, 22/25 finished chemotherapy and 20 of those underwent laparotomy. In 13/25 patients (52%) a R-0 resection and in three cases a R-1 resection were achieved. Four patients stayed irresectable. During 76 completed cycles of chemotherapy we observed five cases of WHO grade-III toxicity and no grade-IV toxicity. CONCLUSIONS The presented PLF protocol yields R-0 resection rates comparable to protocols like EAP (etoposide, adriamycin, platinum), but with a better safety profile allowing administration in an outpatient setting. Our study supports PLF as a reference neoadjuvant treatment for gastric cancer even outside of clinical studies.

Abstract
Despite marked decreases in incidence over the last century, particularly in developed countries, gastric cancer is still the second-most common tumor worldwide. Surgery remains the gold standard for the cure of locoregional disease. However, in most countries, the diagnosis is made at an advanced stage, and the 5-year survival for surgically resectable disease stays far below 50%. The efficacy of chemotherapy and/or radiation therapy in addition to surgery has been actively studied over the last 30 years. Unfortunately, with few exceptions, most studies of adjuvant therapy in gastric cancer have given deceiving results. The purpose of this review is to address the reasons for our failure to objectivate an improvement in the cure of gastric cancer with adjuvant treatment in most trials, and to consider potential solutions. The low efficacy of chemotherapy regimens available up to now may have hampered our progress. In addition, many previous studies suffered limitations of design or methodology (e.g. low accrual, inadequate disease stage selection, inadequate surgical treatment) that may have obscured a treatment effect. Furthermore, the reduced treatment tolerance of post-gastrectomy patients, perhaps due to their poor nutritional status, results in decreased or delayed adjuvant systemic therapy, with potential adverse consequences in its efficacy. Among potential solutions, the arrival of new drugs, taxanes and topoisomerase I inhibitors in particular, which have shown encouraging results in metastatic disease, may increase the impact of chemotherapy in a multidisciplinary treatment approach. Pre-treatment with chemotherapy and/or radiation therapy prior to surgery may also be advantageous, averting the problems associated with post-surgical treatment. Such an approach has been shown to be feasible in phase II studies, and is relatively well tolerated by patients. Several carefully designed randomized phase III trials are underway to answer this question.

Abstract
AIM: To assess the safety and efficacy of different intravenous chemotherapeutic regimens in patients with gastric carcinomas who had undergone gastrectomy.
METHODS: A meta-analysis of all the relevant randomized controlled trials (RCTs) was performed. Language was restricted to Chinese and English. RCTs were identified from Medline and Embase (1980-2001/4), and Chinese Bio-medicine Database (1990-2001/1). Literature references were checked at the same time. We included randomized and quasi-randomized trials comparing the efficacy of intravenous chemotherapy after gastrectomy with that of surgery alone in patients with confirmed gastric carcinomas who had undergone gastrectomy. Selection criteria were: randomized or quasi-randomized trials with following-up results; Trials could be double-blind, single-blind or not blind; Chemotherapy groups were given intravenous chemotherapy after gastrectomy without neo-adjuvant chemotherapy, intraperitoneal hyperthermic perfusion, radiotherapy or chemoimmunotherapy; Controlled group included those receiving gastrectomy alone. The following data were extracted: the number of survival and death by the end of the follow-up; the different agents and doses of the intravenous chemotherapy; the baseline of the chemotherapy group and the controlled arm; the serious adverse events; the statistical consideration; cost-effectiveness analysis. The statistical analysis was performed by RevMan4.1 software which was provided by the Cochrane Collaboration. A P value of < 0.05 was considered statistically significant. Meta-analysis was done with random effects model. Heterogeneity was checked by chi-square test. Sensitivity analysis was performed by excluding the trials in which Jadad-scale was only 1 score. The result was expressed with odds ratio (OR) for the categorical variable.
RESULTS: Fourteen trials involving 4543 patients were included. Meta-analysis was done with random effects model Heterogeneity and sensitivity analysis were performed also. The effect of intravenous chemotherapy after gastrectomy was better than surgery alone (odds ratio 0.56, 95%CI 0.40-0.79). There was a significant difference between the two groups by u-test (P = 0.0008). Sensitivity analysis revealed the same difference (odds ratio 0.81, 95%CI 0.70-0.94). Of fourteen trials, only three studies were of high quality according to the Jadad-scale (with three score). There was one meta-analysis trial and the others, about ten trials, were of low quality. There was no trial which mentioned sample-size calculation, allocation concealment, intention-to-treat analysis. Most of the trials didn’t describe the blind-procedure. There were five trials which detailed the side-effects according to the toxicity grade by WHO standard. The side-effects halting treatment were haematologic and biochemical toxicity, debilitating nausea and vomiting. There were two patients died of chemotherapy toxicity.
CONCLUSION: Based on the review, intravenous chemotherapy after gastrectomy may have positive treatment effect on gastric cancer. However, the evidence is not strong because of the general low methodologic quality of the RCTs. Therefore, we can’t make the conclusion that intravenous chemotherapy after gastrectomy may have better treatment effect on gastric cancer than that of surgery alone. Rigorously designed, randomised, double-blind, placebo-controlled trials are required.

Abstract
Standard chemotherapy for advanced gastric cancer remains undefined. Two of the most popular regimens-ECF [epirubicin-cisplatin-5-fluorouracil (5-FU)] and PELF (cisplatin-epirubicin-5-FU-leucovorin)-have been shown to be active, but each has limitations. Phase II trials show that single-agent docetaxel is an active agent in advanced gastric cancer, producing overall response rates (ORRs) of 17.5-24%. Docetaxel has also been shown to lack cross-resistance with other drugs in gastric cancer, and is likely to be at least additive to cisplatin and 5-FU. Phase II results of docetaxel combinations in advanced gastric cancer are encouraging. Docetaxel-cisplatin has yielded response rates similar to those achieved by ECF and PELF. Adding 5-FU to docetaxel-cisplatin has achieved an ORR of 52 versus 45% for docetaxel-cisplatin in a randomized phase II trial. Docetaxel-based regimens demonstrate acceptable tolerability despite predictable hematotoxicity. Neutropenia, the major toxicity, is manageable by dose modification or by using prophylactic granulocyte colony stimulating factor. Several phase III trials are now ongoing, including a large-scale trial of docetaxel-cisplatin-5-FU versus cisplatin-5-FU. Results will show whether docetaxel improves overall response and survival, as suggested in the phase II setting.

Abstract
Gastric cancer is the second most frequently diagnosed malignancy worldwide, and the risk of relapse remains high in the majority of patients undergoing resection. Attempts to reduce this risk and prolong survival have led to numerous adjuvant chemotherapy trials that either had no benefit for patients or occasionally had controversial results. The recently reported Intergroup 0116 trial shows conclusive evidence of survival benefit for patients treated with postoperative chemoradiotherapy. In this Intergroup trial, which involves over 600 patients, a regimen of postoperative chemotherapy plus chemoradiotherapy was shown to prolong overall and disease-free survival in gastric cancer patients with stage IB through IV disease following a curative (R0) resection. This approach should be considered the standard of care in patients with gastric cancer who have undergone curative resection. Preoperative chemotherapy shows promise in downstaging tumors and increasing the rate of curative resection, but randomized trials are needed to assess survival benefits. Efforts to combine existing treatment modalities and new agents with novel mechanisms of action hold promise for the future.

Abstract
Forty-four patients with gastro-esophageal tumors regarded as resectable by conventional staging underwent laparoscopic ultrasonography (LUS). Following LUS, seven were found to be irresectable and were managed by palliative therapies. Thirty-seven patients proceeded to surgical exploration and 36 were resected (R0 80%, R1 11%, and R2 9%). All patients were reviewed until death or for a minimum of 24 months. Patients undergoing resection had a 62% 1-year survival (median 17 months; confidence intervals, CI 6-28). LUS defined nodal status indicated a trend toward prolonged survival in the node-negative group, median 22 months (CI 5-39), compared with 13 months (CI 6-20) in the node-positive group. Disease-free survival was greater in LUS node-negative patients at 29 months (CI 23-35) compared with node-positive patients at 13 months (CI 5-21) P=0.0083. LUS staging allows prediction of the likelihood of recurrence of gastro-esophageal malignancies. This may prove useful for the appropriate allocation of patients to primary and adjuvant therapies.

Abstract
Gastric adenocarcinoma is the most common malignancy of the upper gastrointestinal tract. During the past two decades it has migrated toward the gastroesophageal junction. Gastroesophageal reflux and obesity may play a role. Recent research suggests that a number of biologic and molecular differences exist in patients with gastric cancer. Further investigation in these areas may help in predicting outcome and directing therapy. Gastric cancer is not a curable condition when metastases are present. However, postoperative chemotherapy plus chemoradiotherapy, in the Intergroup trial 0116, prolonged the overall and disease-free survival rates of patients after a curative (R0) resection. It should be considered the new standard of care in patients with gastric cancer who have undergone curative resection with stage Ib-IV disease. Preoperative therapy strategies may increase the likelihood of R0 resection and remain an area of active investigation. Finally, development of more active agents is needed for the treatment of metastatic tumors.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) is a standard procedure in the preoperative staging of patients with gastric carcinomas. Herein we present our experience with EUS and discuss the results and their implications for surgical therapy. METHODS A total of 116 patients with histologically confirmed gastric adenocarcinoma were referred to EUS and classified prospectively by the TNM system. The results of the preoperative endosonographic staging were compared with the definitive histopathological results after the operation. RESULTS The overall accuracy of EUS for determination of the T stage was 78%. The accuracy for the T1 and T2 stages was 80% and 63%, respectively. With 20% and 30%, there was a relatively high rate of overstaging in these cases. The accuracy for T3 and T4 tumors was 95% and 83%, respectively. The accuracy of EUS for determination of the N stage was 77%, with a sensitivity of 91% and a specificity of 84%. Resectability was predicted correctly with a sensitivity of 94% and a specificity of 83%. CONCLUSIONS Generally accepted standards for the therapy of advanced gastric carcinomas do not exist. In cases where the therapeutic strategy is surgical exploration, no preoperative staging is necessary. In cases with differentiated treatment strategies, the accuracy of EUS is not sufficient for the selection of patients for endoscopic resection. Its accuracy for submucosal cancer invasion and for the detection of lymph node metastases needs to be further enhanced. If only multimodal therapy is considered, EUS staging seems to be absolutely mandatory. Patients classified preoperatively as T1 to T3 can be operated on primarily with sufficient security. In patients where radical resection of the tumor seems doubtful, we recommend that a diagnostic laparoscopy be performed to confirm the diagnosis.

Abstract
BACKGROUND The effectiveness of some chemotherapeutic agents used to treat gastric carcinoma patients may be impaired by the presence of P-glycoprotein (P-gp) and the status of p53. A modulation of P-gp expression by p53 or other alterations during tumorigenesis have been reported. The authors analyzed P-gp expression in relation to p53 and histopathologic features in gastric carcinoma. METHODS Forty-one resected gastric carcinomas and mucosa distant from the tumor were assessed for P-gp expression by immunohistochemistry with C494 and JSB-1 antibodies. p53 expression was also immunohistochemically assessed by DO7 antibody in tumor samples. P-gp and p53 expression were semiquantitatively analyzed according to the percentage of stained cells. Histologic type, grade, vessel invasion, and stage were also studied. RESULTS Moderate or high P-gp expression was detected in gastric carcinoma in 29 cases (71%) and in gastric mucosa remote from the tumor in 36 cases (88%). This reduction in P-gp expression was observed in 22% of the carcinomas, all but 1 being p53 immunonegative tumors. Thus, 8 (42%) of the p53 immunonegative carcinomas showed a loss of P-gp expression compared with their distant gastric mucosa. All p53 immunopositive carcinomas coexpressed P-gp. No correlation between P-gp expression and histologic type, grade, vessel invasion, or stage was found. CONCLUSIONS P-gp expression in gastric carcinomas is frequent and coexpression with p53 is found. The analysis of P-gp expression in carcinomas and distant mucosa show that it is not regulated by p53, but a loss of P-gp detected in some of these carcinomas is mainly associated with a lack of p53 protein accumulation.

Abstract
Gastric cancer is still a major health problem and a leading cause of cancer mortality despite a worldwide decline in incidence. Environmental and Helicobacter pylori (Hp) acting early in life in a multistep and multifactorial process may cause intestinal type carcinomas, whereas genetic abnormalities are related more to the diffuse type of disease. Primarily due to early detection of the disease, the results of treatment for gastric cancer have improved in Japan, Korea and several specialized Western centres. Surgery offers excellent long-term survival results for early gastric cancer (EGC). Advances in diagnostic and treatment technology have contributed to a trend towards minimal invasive surgery such as endoscopic mucosal resection (EMR) and laparoscopic surgery for selected mucosal cancers. In the Western world, however, more than 80% of patients at diagnosis have an advanced gastric cancer with a poor prognosis. The aim of surgery is complete removal of the tumour (UICC R0-resection), which is known to be the only proven, effective treatment modality and the most important treatment-related prognostic factor. Gastrectomy with preservation of the spleen and pancreas in most cases is the standard procedure. However, at present there is no consensus about the optimal extent of lymph-node dissection. The hypothesis that extended (D2) lymph-node dissection leads to improved survival has not been confirmed in randomized trials. Results from specialized centres and ongoing multi-institutional randomized trials, however, indicate that D2 dissection, with preservation of the spleen and pancreas, can be performed with the same safety as a D1 dissection. Furthermore, in 50% of patients with node-positive disease, the extraperigastric N2 nodes are involved (N2 disease) and thus an R0-resection is achievable only by a D2 node dissection resulting in a 5-year survival of about 30% for such patients. However, even after a D2 node dissection with curative potential, disease recurs in two-thirds of patients with locally advanced gastric cancer (LAGC) and is rapidly fatal. The need for an adjuvant treatment is obvious, but at present there is no such treatment of proven effectiveness. Promising results with preoperative chemotherapy, which increases the R0-resection rate, and intra-or early postoperative intraperitoneal chemohyperthermia to prevent peritoneal dissemination have been reported. However, randomized trials are necessary before these combined treatments become widely accepted. Present data indicate that the treatment of gastric cancer has become more and more sophisticated with a tailored therapy for individual cases. Treatment includes a broad spectrum of therapeutic options from EMR for selected mucosal cancers to aggressive combined treatment for LAGC. Precise knowledge of patterns of recurrence and metastases, critical evaluation of clinicopathologic variables, integration of high technology into diagnosis to predict accurately pre-treatment staging, and the surgeon's ability to perform minimally invasive surgery and D2 node dissection technique are necessary for an appropriate treatment option. All these prerequisites are best ensured by management in experienced surgical oncology units.
