Postoperative Adjuvant Chemoradiotherapy on the Survival of Stage III Gastric Cancer. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:8036763. [PMID: 35799652 PMCID: PMC9256314 DOI: 10.1155/2022/8036763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 06/09/2022] [Accepted: 06/13/2022] [Indexed: 11/18/2022]
Abstract
Objective Although adjuvant therapy has been shown to be beneficial in gastric cancer, the use of adjuvant chemoradiotherapy remains controversial. This paper investigated the effects of postoperative adjuvant chemoradiotherapy on the survival of patients with stage III gastric cancer. Methods In total, the data of 72 stage III gastric cancer patients treated at our hospital from January 2014 to December 2019 were retrieved and assessed. They were categorized into a chemotherapy group (CT group) and a radiochemotherapy group (RCT group) according to their given treatment regimens. A 3-year follow-up was conducted to record their incidence of disease-free survival (DFS), overall survival (OS), and adverse events. Results For the CT and RCT groups, DFS was 86.4% and 92.6% in the first year, decreasing to 55.1% and 73.7% in the second year, and 41.3% and 69.1% in the third year. There was no significant difference in DFS between the two groups during the three-year follow-up. Additionally, for the CT and RCT groups, their respective 1-year, 2-year, and 3-year OS were 95.6% and 96.3%, 75.1% and 87.9%, and 50.3% and 74.2%, indicating that the OS of patients in the RCT group was significantly higher than that in the CT group during 3 years of follow-up. Further, no significant difference in the incidence of adverse events was found between the two treatment groups. Conclusions Collectively, adjuvant radiochemotherapy after radical gastrectomy for stage III gastric cancer was associated with better survival outcomes than chemotherapy, without increase in adverse events.

Abstract
A β-galactosidase activatable fluorescent turn-on theranostic Gal-CGem exhibits gemcitabine release specifically in β-galactosidase overexpressing hepatic carcinoma cells. The cytotoxicity of Gal-CGem in cancer cells is achieved through the apoptotic cell death pathway. Overall, Gal-CGem is a new frontline prodrug in cancer therapy that has provided antineoplastic information through fluorescence imaging.

Abstract
PURPOSE To assess the value of adjuvant radiotherapy for treatment of gastric adenocarcinoma and to investigate subgroups of patients suitable for adjuvant radiotherapy. METHODS AND MATERIALS Data from 785 patients with gastric adenocarcinoma who had undergone D1/D2 radical resection and adjuvant chemotherapy were collected, the site of first progression was determined, and the relationship between the rate of local recurrence and clinicopathologic features was analyzed. RESULTS By the end of the follow-up period, progression was observed in 405 patients. Local recurrence was observed as the first progression in 161 cases. The local recurrence rate was significantly lower than the non-local progression rate (20.5% vs 31.5%, p=0.007). Multivariate Cox regression analysis showed a significant relationship among degree of differentiation, T stage, N stage, and rate of local recurrence. CONCLUSIONS Not all patients with gastric carcinoma required adjuvant radiotherapy. However, patients with poorly differentiated cancer cells, advanced T stage (T3/T4), and positive lymph nodes, which included patients in the T4N1-2M0 subgroup, were recommended for adjuvant radiotherapy.

Abstract
Background: A consensus regarding optimum treatment strategies for locally advanced gastric cancer (LAGC) has not yet been reached. We aimed to evaluate the efficacy of various treatment modalities for LAGC and provided clinicians salvage options under real-world situation. Methods: Medical charts of patients with LAGC who underwent radical resection plus adjuvant chemotherapy or chemoradiotherapy from July 2003 to December 2014 were included. Validation cohort were selected from SEER database between 2004 and 2014. Kaplan-Meier and Cox proportional hazardous models were used to evaluate the overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS). Propensity score matching (PSM) was used to adjust for potential baseline confounding. Results: A total of 350 patients were included and divided into D1 dissection plus chemotherapy group (D1CT, n = 74), D1 dissection plus adjuvant chemoradiotherapy group (D1CRT, n = 69), D2 dissection plus adjuvant chemotherapy group (D2CT, n = 134), and D2 dissection plus adjuvant chemoradiotherapy group (D2CRT, n = 73). PSM identified 50 patients in each group. After PSM, better DFS (P for D2CRT vs. D1CT, D1CRT, and D2CT was 0.001, 0.006, and 0.001, respectively) and OS (P for D2CRT vs. D1CT, D1CRT, and D2CT was 0.001, 0.011, and 0.022, respectively) were found for the D2CRT group (mean, OS = 110.7months, DFS = 95.2 months) than the other groups. Similar findings were further validated in the Surveillance, Epidemiology, and End Results database (SEER) cohort. In addition, patients in the D1CRT group achieved similar survival outcomes to those in the D2CT group (mean OS, 72.8 vs. 59.1 months, P = 0.86; mean DFS, 54.4 vs. 34.1 months, P = 0.460). Conclusions: The results of the study indicated the better role for D2CRT in treating the LAGC, meanwhile, the patients treated with D1CRT might achieve similar survival as that of D2CT patients.

Abstract
Objectives: The strategy for the treatment of stage IV gastric cancer remains controversial. The objective of this study was to assess whether tumor resection is beneficial to survival in gastric cancer patients with incurable stage IV disease. Methods: This is a retrospective cohort study of gastric cancer patients in the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2015. Due to the baseline bias, 1:1 propensity score matching (PSM) was used in this cohort. Patients were grouped by treatment, (1) gastrectomy with chemoradiotherapy (CRT), or (2) CRT only, and a Cox proportional hazards regression model was used to identify predictors of survival. Overall survival was compared between the two groups using the Kaplan-Meier method. Result: After propensity score matching, 162 stage IV gastric cancer patients diagnosed from 2010 to 2015 were identified. Among these patients, half underwent gastrectomy with CRT, while the others received CRT only. The median overall survival rates were 22 months from the date of surgery for the gastrectomy with CRT group and 9.0 months for CRT only group. In the multivariable Cox regression analysis, surgery was associated with a significant improvement in overall survival [hazard ratio (HR) of death = 0.31, 95% confidence interval (CI) = 0.21-0.46, P < 0.0001]. Conclusion: In conclusion, stage IV gastric cancer is still a fatal disease. This population-based study found that compared with CRT alone, CRT with gastrectomy may be associated with a survival benefit in patients with metastatic GC. In selected patients' survival can be prolonged when the primary tumor is removed. Prospective, randomized trials are required to determine the best strategy for metastatic GC and to describe the characteristics of the selected patients.

Abstract
The INT0116 trial was a milestone study and laid the foundation for the adjuvant radiotherapy (RT) associated to concurrent chemotherapy (CT) for the treatment of gastric cancer (GC) after gastrectomy. However, it is still controversial whether adding RT to CT could further benefit D2-dissected GC patients. The ARTIST trial indicated that the addition of RT to CT did not have a positive impact on disease-free survival (DFS). Nevertheless, in a subgroup of 396 patients with positive pathological lymph nodes, combined treatment with RT was superior to CT alone. A similar randomized Chinese trial confirmed the superiority of adding RT to CT in terms of DFS for patients with D2 lymphadenectomy. However, several previous randomized studies provided inconsistent results with the benefits of combined treatment of RT and CT. The inconsistent results of several studies may be due to the differences between tumor epidemiology, treatment policies, and treatment outcomes. During the past decade, major progress in accurate target delineation utilizing RT technology has been observed. However, even though the use of adjuvant RT doubled after the INT-0116 trial results became public, the fraction of patients receiving adjuvant RT was still low according to the SEER database. The low rate of adjuvant RT can partially be explained by concern over toxicity while undergoing RT. Several studies have also defined the specific location of locoregional recurrence for postoperative RT in GC, but these studies are still limited. A number of retrospective studies demonstrated that the most prevalent nodal recurrence was outside the D2 dissection field. In order to overcome the restricted nature of a retrospective study and provide more individual radiation field determination, additional large-scale prospective multicenter studies are required to evaluate the optimal RT target.

Abstract
Purpose: Gastric cancer is mainly treated by gastrectomy, the results of which were unsatisfactory without any adjuvant treatments. This study aimed to examine the performance of radiotherapy, chemotherapy, and chemoradiotherapy after surgery in order to acquire the optimal adjuvant treatment. Method: Embase and PubMed were retrieved to conduct a systematic research. Hazard ratios (HR) of overall survival (OS) and progression-free survival (PFS) as outcomes were calculated by synthesizing direct and indirect evidence to evaluate the efficacy of three treatments against surgery alone. The P-score ranking was utilized to rank the therapies. Consistency was assessed by heat plot. Begg's test was performed to evaluate publication bias. Results: A total of 35 randomized controlled studies (RCTs) with 8973 patients were included in our network meta-analysis (NMA). As for efficacy outcomes, OS and PFS of 1, 2, 3, and 5 years, all revealed chemoradiotherapy (CRT) as the best of three adjuvant therapies. Meanwhile, P-score ranking results also displayed that CRT was the optimal regimen. Additionally, radiotherapy (RT) and chemotherapy (CT) were two alternative options following CRT since RT performed well in short-term survival while CT could improve the long-term survival. Conclusion: CRT was the most recommended therapy to accompany surgery according to our results. However, no analysis about the safety of these three treatments was mentioned in our study. Further studies including safety outcomes were required to draw a more comprehensive conclusion.

Abstract
Gastric (GC) and gastro-oesophageal (GOJC) adenocarcinomas are often considered as a single entity, even though differences exist in epidemiology, clinical presentation, molecular biology and treatment options. Locally advanced, resectable disease represents a particularly challenging scenario, as many critical issues need to be addressed. In both GC and GOJC among Western countries, systemic chemotherapy demonstrated the greatest benefit when administered before and after surgery and perioperative chemotherapy has been set as a standard in this setting. Nonetheless, multiple chemotherapy regimens have been tested and direct comparisons have been only recently presented. Adjuvant chemoradiotherapy is an option as well, but several trials have questioned its role when more effective combination regimens are used. With regards to GOJC, preoperative chemoradiotherapy is an alternative to perioperative chemotherapy, as it is associated with higher pathologic responses and a different toxicity profile: however, a definitive comparison with chemotherapy is ongoing. Herein, we review the current options for the treatment of resectable GC and GOJC and the main open questions in the management of these patients, trying to depict an update of the available algorithms for everyday practice. Moreover, we summarize the design and preliminary results of the randomized trials in progress that will hopefully give definitive answers to the most debated issues in the field.

Abstract
Background Myosin phosphatase target subunit 1 (MYPT1) serves as a subgroup of myosin phosphatases, and is frequently low-expressed in human cancers. However, little is known about the effects of MYPT1 in gastric cancer (GC). Material/Methods In our study, MYPT1 expression was detected by quantitative real-time reverse transcription PCR (qRT-PCR) in GC tissues, different advanced pathological stages of GC tissues, and preoperative and postoperative patients. Kaplan-Meier analysis was used to measure the overall survival of GC patients. MYPT1 expression was analyzed by qRT-PCR and Western blot assays in GES-1 cells and GC cells. Cell proliferation, cycle, and migration and invasion abilities were detected by CCK-8, flow cytometry, and Transwell assays. E-cadherin, TIMP-2, MMP-2, MMP-9 RhoA, and p-RhoA expressions were assessed by qRT-PCR and Western blot assays in treated SNU-5 cells. Results Our results indicated that MYPT1 was down-regulated in GC tissues and cells, and is related to clinical stages and overall survival of GC. Functional research demonstrated that overexpression of MYPT1 can inhibit cell proliferation, cell cycle progression, and migration and invasion of GC cells. Many studies on mechanisms reported that overexpression of MYPT1 dramatically improved the expression levels of cell cycle-related genes (Cyclin D1 and c-myc), significantly increased epithelial marker (E-cadherin) expression, and decreased invasion-associated genes (TIMP-2 and MMP-2) expressions in SNU-5 cells. In addition, we found that MYPT1 suppressed RhoA phosphorylation. Conclusions We verified that MYPT1 inhibits GC cell proliferation and metastasis by regulating RhoA phosphorylation.

Abstract
BACKGROUND While the curative approach to gastric cancer includes perioperative regimens in several countries, a substantial proportion of patients may not receive treatment prior to surgery. This study examines the adjuvant provision of chemoradiotherapy (CRT) for non-pretreated patients with cancer of the stomach including the gastric cardia. METHODS All surgically treated patients with primary adenocarcinoma of the stomach and gastric cardia diagnosed between January 2004-December 2013 were selected from the Netherlands Cancer Registry. Patients who did not receive neoadjuvant treatment were included. Early gastric cancers (cT1), postoperative deaths within 90 days, patients with metastatic disease (M1), patients who received adjuvant chemotherapy and patients with macroscopic tumor after surgery (R2) were excluded. RESULTS Some 3277 patients underwent surgery, and 99 patients (3%) received adjuvant CRT. Treatment was more often administered in patients with a younger age (<65 years) and a high socioeconomic status (SES), in case of non-cardia cancer, positive lymph nodes, and positive resection margins (R1). Median survival time was 28 months (95% CI 17-39), compared to 35 months (95% CI 33-38) in CRT-naïve patients. After adjustment for confounders, a small net benefit for adjuvant CRT was found (hazard ratio, HR: 0.75, 95% CI 0.58-0.96). In subgroup analyses, benefit was most pronounced for patients with seven or more lymph metastases. CONCLUSIONS Marginal survival benefit was observed for adjuvant CRT in gastric cancer patients who did not receive neoadjuvant treatment. Treatment could be considered for patients with disease involving nodal invasion and those left with microscopic residual disease after surgery.

Abstract
BACKGROUND Gastrointestinal (gi) symptoms are the most notable side effects of chemotherapeutic drugs; such symptoms are currently treated with drugs. In the present study, we investigated the effect of acupuncture on gi symptoms induced by chemotherapy in patients with advanced gastric cancer. METHODS A cohort of 56 patients was randomly divided into an experimental group and a control group. All patients received combination chemotherapy with oxaliplatin-paclitaxel. Patients in the experimental group received 30 minutes of acupuncture therapy daily for 2 weeks. The frequency and duration of nausea, vomiting, abdominal pain, and diarrhea, the average days and costs of hospitalization, and quality-of-life scores were compared between the groups. RESULTS Nausea was sustained for 32 ± 5 minutes and 11 ± 3 minutes daily in the control and experimental groups respectively (p < 0.05). On average, vomiting occurred 2 ± 1 times daily in the experimental group and 4 ± 1 times daily in the control group (p < 0.05). Abdominal pain persisted for 7 ± 2 minutes and 16 ± 5 minutes daily in the experimental and control groups respectively (p < 0.05). On average, diarrhea occurred 1 ± 1 times daily in the experimental group and 3 ± 1 times daily in the control group (p < 0.05). The average quality-of-life score was higher in the experimental group than in the control group (p < 0.05). No adverse events were observed for the patients receiving acupuncture. CONCLUSIONS Acupuncture, a safe technique, could significantly reduce gi symptoms induced by chemotherapy and enhance quality of life in patients with advanced gastric cancer.

Abstract
Gastric cancer remains frequent and one of the most lethal malignancies worldwide. In this article, we aimed to comprehensively review recent insights in the therapeutic management of gastric cancer, with focus on the surgical and perioperative management of resectable forms, and the latest advances regarding advanced diseases. Surgical improvements comprise the use of laparoscopic surgery including staging laparoscopy, a better definition of nodal dissection, and the development of hyperthermic intraperitoneal chemotherapy. The best individualized perioperative management should be assessed before curative-intent surgery for all patients and can consists in perioperative chemotherapy, adjuvant chemo-radiation therapy or adjuvant chemotherapy alone. The optimal timing and sequence of chemotherapy and radiation therapy with respect to surgery should be further explored. Patients with advanced gastric cancer have a poor prognosis. Nevertheless, they can benefit from doublet or triplet chemotherapy combination, including trastuzumab in HER2-positive patients. Upon progression, second-line therapy can be considered in patients with good performance status. Although anti-HER2 (trastuzumab) and anti-VEGFR (ramucirumab) may yield survival benefit, anti-EGFR and anti-HGFR therapies have failed to improve outcomes. Nevertheless, combination regimens containing cytotoxic drugs and targeted therapies should be further evaluated; keeping in mind that gastric cancer biology is different between Asia and the Western countries.

Abstract
The discrepancy between the surgical technique and the type of adjuvant chemotherapy used in clinical trials and patient outcomes in terms of overall survival rates has led to the generation of different adjuvant treatment protocols in distinct parts of the world. The adjuvant treatment recommendation is generally chemoradiotherapy in the United States, perioperative chemotherapy in the United Kingdom and parts of Europe, and chemotherapy in Asia. These options mainly rely on the United States Intergroup-0116, United Kingdom British Medical Research Council Adjuvant Gastric Infusional Chemotherapy, and the Asian Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer and Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer trials. However, the benefits were evident for only certain patients, which were not very homogeneous regarding the type of surgery, chemotherapy regimens, and stage of disease. Whether the dissimilarities in survival are attributable to surgical technique or intrinsic biological differences is a subject of debate. Regardless of the extent of surgery, multimodal therapy may offer modest survival advantage at least for diseases with lymph node involvement. Moreover, in the era of individualized treatment for most of the other cancer types, identification of special subgroups comprising those who will derive more or no benefit from adjuvant therapy merits further investigation. The aim of this review is to reveal the historical evolution and future reflections of adjuvant treatment modalities for resected gastric cancer patients.

Abstract
PURPOSE Surgery is the only possible curative treatment for gastric cancer. However, the high recurrence rate makes gastric cancer difficult to cure by surgery alone. The present study was conducted to evaluate the clinical outcomes and toxicity of adjuvant treatment, including S-1/cisplatin chemotherapy followed by radiotherapy with concurrent S-1. METHODS Patients with radically D2-resected adenocarcinoma of the stomach of stage IB-IV (M0) were eligible. Patients were treated with S-1 (40-60 mg depending on the patient's body surface area) twice daily for 3 weeks and cisplatin (60 mg/m(2)) intravenously on day 1 every 5 weeks. Patients received CRT (45 Gy of radiation at 1.8 Gy/day, 5 days per week, for 5 weeks with the same dose of S-1 during radiation) followed by two additional cycles of S-1/cisplatin. The primary endpoint was the 3-year disease-free survival (DFS) rate; the secondary endpoints were the 3-year overall survival rate and toxicities. RESULTS Until May 2012, 46 patients were enrolled, and 34 (73.9%) completed the planned treatment. The median age was 53 years (range: 31-69 years), and the numbers of patients with stage IB, II, III and IV disease were 0, 17, 25 and 4, respectively. Main grade 3-4 toxicities were as follows: neutropenia (28.2%), nausea (17.4%), vomiting (8.7%) and anorexia (15.2%). At the time of analysis, after a median follow-up period of 56.5 months (3.03-74.0 months), 16 recurrence events and 15 deaths were reported. The estimated 3-year DFS and survival rates were 65.2 and 76.1%, respectively. The most common site of recurrence was the peritoneum (n = 12). CONCLUSIONS The results of this phase II study show that intensified adjuvant treatment with S-1/cisplatin chemotherapy and S-1-based chemoradiotherapy was tolerable and effective in reducing disease recurrence. The addition of radiotherapy to chemotherapy may be effective in D2-resected gastric cancer. Although the data here are promising, a randomized trial is needed between patients treated with the current regimen and an appropriate comparator arm.

Abstract
PURPOSE The aim of this study was to assess the significance of the correlation among tissue carcinoembryonic antigen (CEA) expression with serum CEA (sCEA) levels and long-term survival to highlight the clinical prognostic significance of tissue CEA expression in gastric cancer patients. METHODS Immunohistological method and radioimmunoassay were used to assess tissue and sCEA expression, respectively. Univariate and multivariate analyses were performed to determine correlations, and the Kaplan-Meier method was used to investigate the prognostic significance. RESULTS Our results demonstrate that tissue CEA in gastric cancer is significantly correlated with preoperative sCEA levels (p = 0.031), depth of invasion (p = 0.001), lymph node metastasis (p < 0.001), distant metastasis (p = 0.001), and TNM staging (p < 0.001). The 5-year survival rates were 67.6, 53.9, and 40.1 % for negatively, moderately, and intensely positively stained tissues (p < 0.001), and 57.0 and 37.9 % for serum with normal and elevated CEA expression (p = 0.031). Multivariate analysis revealed that tissue CEA can be considered an independent prognostic factor. Further analysis illustrated that patients with negative expression in both tissue and serum had better prognosis compared with those positively expressing CEA in both tissue and serum and/or those positively expressing CEA in either tissue or serum (p < 0.001). Our results also demonstrated that patients with negative tissue CEA staining and elevated sCEA expression had a better 5-year survival. CONCLUSION Tissue CEA expression in gastric cancer is directly correlated with sCEA levels and long-term prognosis. Thus, tissue CEA expression can be considered as a useful biomarker to improve the interpretation of sCEA levels in predicting long-term survival.

Abstract
Despite overall progress in the therapy of local and locally advanced esophageal, gastroesophageal junction, and gastric adenocarcinomas, death as a result of these tumors remains a common outcome. Most randomized phase III trials on which level-one evidence has been built have included the heterogeneous histologies and locations associated with these tumors. However, the different etiologies, molecular biology, and recurrence patterns associated with gastroesophageal malignancies suggest the need to split rather than lump. Biologic and response differences exist between squamous and adenocarcinomas, as well as diffuse and intestinal histologies. This may be a cause behind conflicting outcomes in similar trials. The accepted standard of chemoradiotherapy for locally advanced esophageal and gastroesophageal junction cancers is based on a few positive trials, with the best chemotherapy and total dose of radiation remaining controversial. In the West, the staging evaluations of locally advanced gastric cancer are not uniform. Yet, these evaluations will inform the results of preoperative and perioperative treatments. Although postoperative chemoradiotherapy for gastric cancer has been an accepted treatment option for the last decade, more recent studies have called into question the need for radiotherapy. In perioperative strategies, it has yet to be determined whether histologic or molecular changes in the operative specimen should inform postoperative treatment. An appropriate place for targeted therapy needs to be found in preoperative and postoperative treatment regimens. Finally, because so much is lost when trials are forced to close for lack of accrual, it is imperative to build multidisciplinary consensus before they are launched.

Abstract
Gastric cancer is one of the main cancer-related causes of death worldwide. The curative treatment of gastric cancer consists of tumor resection and lymphadenectomy. However, surgical treatment alone is associated with high recurrence rates. Adjuvant treatment strategies have been studied over the last decades, but there have been controversial results from the initial studies. The pivotal INT0116 study demonstrated that the use of adjuvant chemoradiotherapy with 5-fluorouracil increases relapse-free and overall survival, and it has been adopted across the Western world. The high toxicity of radiochemotherapy and suboptimal surgical treatment employed, with fewer than 10% of the patients submitted to D2 lymphadenectomy, were the main study limitations. Since its publication, other adjuvant treatment modalities have been studied, and radiochemotherapy is being refined to improve its efficacy and safety. A multimodal approach has been demonstrated to significantly increase relapse-free and overall survival, and it can be offered in the form of perioperative chemotherapy, adjuvant chemoradiotherapy or adjuvant chemotherapy, regardless of the extent of lymphadenectomy. The objective of the present review is to report the major advances obtained in the last decades in the adjuvant treatment of gastric cancer as well as the perspectives of treatment based on recent knowledge of the molecular biology of the disease.

Abstract
Adenocarcinoma of the stomach carries a poor prognosis and is the second most common cause of cancer death worldwide. It is recommended that surgical resection with a D1 or a modified D2 gastrectomy (with at least 15 lymph nodes removed for examination) be performed in the United States, though D2 lymphadenectomies should be performed at experienced centers. A D2 lymphadenectomy is the recommended procedure in Asia. Although surgical resection is considered the definitive treatment, rates of recurrences are high, necessitating the need for neoadjuvant or adjuvant therapy. This review article aims to outline and summarize some of the pivotal trials that have defined optimal treatment options for non-metastatic non-cardia gastric cancer. Some of the most notable trials include the INT-0116 trial, which established a benefit in concurrent chemoradiation and adjuvant chemotherapy. This was again confirmed in the ARTIST trial, especially in patients with nodal involvement. Later, the Medical Research Council Adjuvant Gastric Infusional Chemotherapy trial provided evidence for the use of perioperative chemotherapy. Targeted agents such as ramucirumab and trastuzumab are also being investigated for use in locally advanced gastric cancers after demonstrating a benefit in the metastatic setting. Given the poor response rate of this difficult disease to various treatment modalities, numerous studies are currently ongoing in an attempt to define a more effective therapy, some of which are briefly introduced in this review as well.

Abstract
INTRODUCTION This study conducted a systematic review and meta-analysis (direct and indirect) of published randomised controlled trials (RCTs) to compare the effects of postoperative chemo-radiotherapy (ChRT) with chemotherapy (Ch) on overall and disease-free survival (DFS) for patients with resectable gastric cancer. METHODS We searched MEDLINE and CENTRAL from the date of inception and annual meeting proceedings of American Society of Clinical Oncology and American Society for Radiation Oncology from 1999 to November 2012 for RCTs comparing postoperative ChRT with Ch, postoperative ChRT with surgery alone and postoperative Ch with surgery alone. The primary outcome was overall survival (OS); secondary outcomes included DFS and toxicity. Hazard ratios (HRs), confidence intervals (CIs) and P values (P) were estimated with fixed effects models using Revman 5.1. RESULTS We found six trials comparing postoperative ChRT with Ch (n = 1171). Meta-analysis of direct comparison trials showed that postoperative ChRT significantly improved both OS (HR 0.80, 95% CI 0.65-0.98, P = 0.03) and DFS (HR 0.76, 95% CI 0.63-0.91, P = 0.003) when compared with Ch. There were no significant differences in toxicity between the two groups. CONCLUSIONS This study suggests a survival benefit of postoperative ChRT over Ch in patients with resected gastric cancer.

Abstract
PURPOSE This study evaluated the efficacy and safety of adjuvant chemotherapy with the docetaxel plus cisplatin and 5-fluorouracil (5-FU) (DCF) regimen in patients with gastric cancer. PATIENTS AND METHODS Thirty-two patients with gastric or gastroesophageal junction cancer were enrolled in this study after undergoing radical resection. The patients received the following chemotherapy: docetaxel (60 mg/m(2)) on day 1, cisplatin (12 mg/m(2) per day) on days 1 to 5, and 5-FU (2500 mg/m(2)) continuous infusion for 120 hours, repeated every 3 weeks for six cycles. The primary end point was disease-free survival (DFS). RESULTS The median DFS was 17.0 months. The 1-year DFS was 72%, and the 2-year DFS was 37.5%. The median overall survival was 28.0 months. Using univariate analysis, the technique of lymph node dissection was a predictor for postoperative relapse. The median DFS was 15.0 months in the D1 group and 18.0 months in the D2 group (P = .043). The most frequent grade 3/4 adverse events were neutropenia (56.25%), diarrhea (9.38%), nausea (6.25%), and vomiting (6.25%); 12.5% of patients developed febrile neutropenia. There were no chemotherapy-related deaths. CONCLUSIONS The modified DCF regimen is an effective adjuvant chemotherapy in gastric cancer. Hematologic toxicity was frequent but manageable. This regimen merits further investigation.
