Abstract
Palliative chemotherapy is known to benefit patients with advanced gastric cancer by palliating symptoms and improving survival. The aim of the present study was to evaluate the efficacy and toxicity of chemotherapy regimens that are commonly used in patients with advanced or recurrent gastric cancer. Patients with advanced or recurrent gastric cancer who were treated by at least two chemotherapy regimens between May 2006 and July 2014 at Zhejiang Cancer Hospital (Hangzhou, China) were retrospectively investigated. Survival was evaluated using the Kaplan-Meier method. A total of 248 patients were reviewed, and 158 were evaluated in the final analysis, with a median age of 57 years and a Karnofsky performance status score of ≥80. The median progression-free survival (PFS) time was 168 days for first-line chemotherapy, 96 days for second-line chemotherapy, and the median overall survival (OS) time was 356 days. Further analysis revealed that patients with the disease controlled [complete response (CR) + partial response (PR) + stable disease (SD)], no matter whether they received first-or second-line chemotherapy, may have had an improved OS compared with patients with disease progression (PD). Patients who were treated with >2 lines of chemotherapy had an improved OS compared those who ceased treatment following failure of the second-line chemotherapy. The cycle number of chemotherapy that patients received was associated with OS. The site of the primary and metastatic tumors was also associated with OS. Other factors, including gender, age, histological type, whether a radical operation was received, and chemotherapy regimens, had no evident association with survival. The toxicities were generally tolerated. Taken together, the results from the present study have demonstrated that an increased cycle number of effective chemotherapy may prolong the survival of patients with advanced gastric cancer. Differences among the chemotherapy regimens had no clear correlation with survival.

Abstract
Chemotherapy is of crucial importance in advanced gastric cancer (AGC) patients, in order to obtain palliation of symptoms and improve survival. To date, no standard chemotherapy regimen has been established for AGC. The purpose of the present study was to evaluate the efficacy and toxicity of the combination regimen of paclitaxel and capecitabine (PX) as first-line chemotherapy in patients with advanced or recurrent gastric cancer. Patients with advanced or recurrent gastric cancer who were treated with PX as first-line chemotherapy between January 2001 and December 2012 at the Zhejiang Cancer Hospital (Hangzhou, China) were retrospectively investigated. Survival was evaluated using the Kaplan-Meier method. In total, 36 patients were enrolled, with a median age of 53.5 years and a Karnofsky performance status (KPS) score of ≥80. A median of 4 PX cycles were administered (range, 2–8 cycles). The median progression-free survival time was 3.7 months [95% confidence interval (CI), 2.9–4.5 months) and the median overall survival time was 12.0 months (95% CI, 9.8–14.1 months). From the 36 patients evaluated, one (2.8%) achieved a complete response, seven (19.4%) achieved a partial response, 24 (66.7%) exhibited stable disease and four (11.1%) exhibited progressive disease. The objective response rate was 22.2% (8/36), and the disease control rate was 88.9% (32/36). All 36 patients were assessed for treatment toxicity. Grade 3 or 4 adverse events included neutropenia (2.8% of patients), hand-foot syndrome (2.8%) and vomiting (2.8%). No neutropenic fever or treatment-related mortalities were observed. PX combination chemotherapy may be a valuable first-line therapy for advanced or recurrent gastric cancer.

Abstract
BACKGROUND Although both oral fluoropyrimidines were reported effective and safe, doubts exist about whether S-1 or capecitabine is more advantageous in advanced gastric carcinoma (AGC). Herein, we performed a meta-analysis to comprehensively compare the efficacy and safety of S-1-based chemotherapy versus capecitabine-based chemotherapy as first-line treatment for AGC. METHODS PubMed/Medline, EmBase, Cochrane library, and China National Knowledge Infrastructure databases were searched for articles comparing S-1-based chemotherapy to capecitabine-based chemotherapy for AGC. Primary outcomes were overall response rate (ORR), time to progression (TTP), overall survival (OS), progression-free probability, and survival probability. Secondary outcomes were toxicities. Fixed-effects model were used and all the results were confirmed by random-effects model. RESULTS Five randomized controlled trials and five cohort studies with 821 patients were included. We found equivalent ORR (38.3% vs. 39.1%, odds ratio [OR] 0.92, 95% confidence interval [CI] 0.69-1.24, P = 0.59), TTP (harzad ratio [HR] 0.98, 95% CI 0.82-1.16, P = 0.79), OS (HR 0.99, 95% CI 0.87-1.13, P = 0.91), progression-free probability (3-month OR 1.02, 95% CI 0.62-1.68, P = 0.94; 6-month OR 1.34, 95% CI 0.88-2.04, P = 0.18) and survival probability (0.5-year OR 0.90, 95% CI 0.61-1.31, P =0.57; 1-year OR 0.97, 95% CI 0.70- 1.33, P = 0.84; 2-year OR 1.15, 95% CI 0.61-2.17, P = 0.66). Equivalent grade 3 to 4 hematological and non-hematological toxicities were found except hand-foot syndrome was less prominent in S-1-based chemotherapy (0.3% vs. 5.9%, OR 0.19, 95% CI 0.06-0.56, P = 0.003). There're no significant heterogeneity and publication bias. Cumulative analysis found stable time-dependent trend. Consistent results stratified by study design, age, regimen, cycle, country were observed. CONCLUSION S-1-based chemotherapy was associated with non-inferior antitumor efficacy and better safety profile, compared with capecitabine-based therapy. We recommended S-1 and capecitabine can be used interchangeably for AGC, at least in Asia.

Abstract
BACKGROUND Gastric carcinoma (GC) is one of the highest cancer-mortality diseases with a high incidence rate in Asia. For surgically unfit but medically fit patients, palliative chemotherapy is the main treatment. The chemotherapy regimen of docetaxel, cisplatin and 5-fluorouracil (DCF) has been used to treat the advanced stage or metastatic GC. It is necessary to compare effectiveness and toxicities of DCF regimen with non-taxane-containing palliative chemotherapy for GC. METHODS PubMed, EmBase, Cochrane Central Register of Controlled Trials and China National Knowledge Infrastructure databases were searched to select relative randomized controlled trials (RCTs) comparing DCF to non-taxane-containing chemotherapy for patients with palliatively resected, unresectable, recurrent or metastatic GC. Primary outcome measures were 1-year and 2-year overall survival (OS) rates. Secondary outcome measures were median survival time (MST), median time to progression (TTP), response rate and toxicities. RESULTS Twelve RCTs were eligible and 1089 patients were analyzed totally (549 in DCF and 540 in control). DCF regimen increased partial response rate (38.8% vs 27.9%, p = 0.0003) and reduced progressive disease rate (18.9% vs 33.3%, p = 0.0005) compared to control regimen. Significant improvement of 2-year OS rate was found in DCF regimen (RR = 2.03, p = 0.006), but not of 1-year OS rate (RR = 1.22, p = 0.08). MST was significantly prolonged by DCF regimen (p = 0.039), but not median TTP (p = 0.054). Both 1-year OS rate and median TTP had a trend of prolongation by DCF regimen. Chemotherapy-related mortality was comparable (RR = 1.23, p = 0.49) in both regimens. In grade I-IV toxicities, DCF regimen showed a major raise of febrile neutropenia (RR = 2.33, p<0.0001) and minor raises of leucopenia (RR = 1.25, p<0.00001), neutropenia (RR = 1.19, p<0.00001), and diarrhea (RR = 1.59, p<0.00001), while in other toxicities there were no significant differences. CONCLUSION DCF regimen has better response than non-taxane containing regimen and could potentially improve the survival outcomes. The chemotherapy-related toxicity of DCF regimen is acceptable to some extent.

Abstract
AIM: To determine whether there is a synergistic effect between oxaliplatin and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in inducing the apoptosis of gastric cancer BGC823 cells.
METHODS: After BGC823 cells were cultured and treated with TRAIL and/or oxaliplatin, cell proliferation was measured using MTT assay; cell apoptosis was determined by flow cytometry after propidium iodide staining; and the distribution of lipid rafts and death receptors 4 (DR4) on cell membrane was analyzed by immunofluorescence staining with anti-cholera toxin B subunit, anti-DR4 antibody and rhodamine-conjugated fluorescent secondary antibody.
RESULTS: After BGC823 cells were treated with 1-1 000 µg/L TRAIL for 24 h, the reduced rates of cell proliferation did not exceed 20%. Treatment with 100 µg/L TRAIL for 24 h induced about 10% inhibition of cell proliferation and 4.12% ± 1.26% cell apoptosis. After BGC823 cells were treated with 1-50 mg/L oxaliplatin for 24 h, it was found that the half maximal inhibitory concentration (IC50) was 37.36 mg/L ± 8.12 mg/L. Treatment with oxaliplatin (38 mg/L, IC50 dose) plus TRAIL resulted in a dramatic increase in cell apoptosis when compared to treatment with TRAIL alone (19.83% ± 4.21% vs 40.42% ± 5.78%, P < 0.05). TRAIL at a concentration of 100 µg/L did not induce obvious lipid raft aggregation or DR4 clustering. Oxaliplatin (38 mg/L) significantly promoted lipid raft aggregation and DR4 clustering and induced the co-localization of DR4 and lipid rafts. Treatment with oxaliplatin and TRAIL for 24 h also induced DR4 clustering into aggregated lipid rafts.
CONCLUSION: Oxaliplatin enhances TRAIL-induced BGC823 cell apoptosis by clustering DR4 into lipid rafts.

Abstract
Chemotherapy has a proven role in advanced and metastatic gastric cancer (AMGC) significantly improving quality of life and prolonging survival compared with best supportive care alone. Multiple regimens have been explored. The choice of treatment should be individualized and tailored to the patient's overall conditions and preference. This manuscript is divided into two sections. The first section illustrates the results of a phase II trial combining weekly irinotecan and low dose capecitabine in the management of untreated AMGC patients. The second section aims to identify the current optimal place of this combination in the management of AMGC in the light of the latest advances. In this manuscript we detail our phase II trial which showed objective response rate of 47% (15 patients), disease stabilization of 28% (9 patients), and overall tumor control rate of 75% (24 patients). Median time to progression and overall survival were 5.8 and 8 months, respectively. Grades III-IV toxicities were reported in 7 cases. Low-dose capecitabine plus irinotecan is effective in the treatment of AMGC with an acceptable toxicity profile. Compared to the recent published data, this combination is indicated in the second-line treatment of AMGC and in the first-line treatment where a contraindication for docetaxel- and/or oxaliplatin-based regimen is present.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of the tumor necrosis factor family that selectively induces apoptosis in cancer cells. However, gastric cancer cells are insensitive to TRAIL. In the present study, we show that oxaliplatin enhanced TRAIL-induced apoptosis of MGC803, BGC823, and SGC7901 cells. Oxaliplatin promoted death receptor 4 (DR4) and death receptor 5 (DR5) clustering into aggregated lipid rafts, while the cholesterol-sequestering agent nystatin partially prevented lipid raft aggregation, DR4 and DR5 clustering, and reduced apoptosis. Furthermore, the expression of the casitas B-lineage lymphoma (Cbl) family was downregulated by oxaliplatin. Transfection of c-Cbl or Cbl-b partially reversed oxaliplatin-induced lipid raft aggregation. These results indicated that oxaliplatin enhanced TRAIL-induced gastric cancer cell apoptosis at least partially through Cbl-regulated death receptor redistribution in lipid rafts.

Abstract
BACKGROUND The prognosis of gastric tumor is generally poor because most tumors are diagnosed at an advanced stage. Chemotherapy has a proven palliative role in advanced gastric cancer and several combination regimens were explored in the last 10 yr. Nevertheless, none of them showed a convincing improvement resulting in an enhancement of response rate and overall survival without discrimination of the quality of life. Irinotecan (CPT11) has been evaluated in multiple trials alone or in combined therapy with promising results and good tolerance. Thus, a review of the importance and impact of CPT11 in this indication is detailed. METHODS This article reviews the evidence for the use of CPT11 in the treatment of gastric cancer based on a computerized MEDLINE search of literature published until August 2006 leading to a total of 91 publications. RESULTS CPT11 was frequently used and showed a good response rate varying from 14% to 23% as single agent and 45% to 70% in combination with a median time to progression of 3 mo in single agent and 4-6 mo in combination, and median overall survival of approx 7 mo in single agent and up to 10.58 mo in combination. CONCLUSION The overall response of irinotecan-based chemotherapy in advanced gastric cancer was shown to be as effective as other combined chemotherapy. The hematological and digestive toxicity were tolerable and mild, especially in weekly regimen. Thus, irinotecan-based chemotherapy should be considered as one of the preferred choices in front line chemotherapy in advanced gastric cancer.

Abstract
From February, 2001 to September, 2002, the Southwest Oncology Group (SWOG) accrued 65 patients with advanced gastric adenocarcinoma to a phase II trial of weekly 5-FU, leucovorin, and the orally-administered uridine analog PN401. Of these 65 patients, 57 were assessable for survival and toxicity, which were the endpoints for the study. Treatment consisted of the administration of 1200 mg/m(2) of 5-FU, 500 mg/m(2) of leucovorin, and 6 grams of PN401 every 8 h, beginning 8 h after the completion of the 5-FU infusion, and continuing for a total of 8 doses (48 grams) during each weekly chemotherapy session. Therapy was delivered for six weeks out of every 8-week treatment cycle. The gastrointestinal toxicity of this regimen was mild with 2 patients experiencing grade 3 stomatitis, and 6 patients having grade 3 diarrhea; and the hematologic toxicity was acceptable with 6 of 57 patients found to have had grade 3 or 4 leukopenia, and 14 of 57 patients experiencing grade 3 or 4 neutropenia. There were two deaths judged possibly related to treatment; one in a patient who experienced a variety of Grade 2 gastrointestinal toxicities and died at home with an unknown cause of death; and a second patient who also died at home, and for whom treatment-related sepsis could not be ruled out. The overall median survival was 7.2 months. The ability to safely deliver twice the usual dose of 5-FU with leucovorin on a weekly schedule suggests that oral uridine analog supplementation with PN401 may enhance the therapeutic index of the fluoropyrimidines.

Abstract
OBJECTIVES Docetaxel, capecitabine, and oxaliplatin are important new agents in esophagogastric cancer. The Brown University Oncology Group initiated a phase I study to determine the maximum tolerated dose of weekly docetaxel, oxaliplatin, and capecitabine. METHODS Patients with metastatic esophageal and gastric cancers received docetaxel and oxaliplatin on days 1 and 8 and capecitabine in divided doses, twice daily, on days 1 to 10, with each cycle repeated every 21 days. Patients were enrolled in cohorts of 3 at escalating dose levels. The docetaxel dose ranged from 30 to 35 mg/m2, the oxaliplatin dose from 40 to 50 mg/m2, and the capecitabine dose from 750 to 850 mg/m2 BID. RESULTS Sixteen patients were enrolled over 4 dose levels. The median age was 59 years. Eight patients had esophageal cancer and 9 had gastric cancer. Grade 3/4 dose-limiting toxicities of diarrhea, nausea, fatigue, and febrile neutropenia occurred in 3 of 4 patients at dose level 3. An intermediate dose level was added (2A), reducing the capecitabine dose to 750 mg/m2. One of 6 patients had a dose-limiting toxicity at level 2A. CONCLUSIONS Oxaliplatin 50 mg/m2 and docetaxel 30 mg/m2 day 1 and 8 with capecitabine 750 mg/m2 BID for 10 days in 21-day cycles may represent a promising, easily administered regimen for metastatic esophageal and gastric cancer. A phase II study will be initiated.

Abstract
In order to define the most effective combination schedule of oxaliplatin (L-OHP) and 5-fluorouracil (5-FU), we investigated the in vitro interaction between these drugs in a panel of four human gastric adenocarcinoma cell lines (MKN-1, NUGC-3, NUGC-5 and AZ-521). Cytotoxic activity was determined by the WST-1 assay. Different schedules of the two drugs were compared and evaluated for synergism, additivity or antagonism with a quantitative method based on the median-effect principle of Chou and Talalay. Cell cycle perturbation and apoptosis were evaluated by flow cytometry. Simultaneous and sequential treatments of L-OHP followed by 5-FU exhibited synergistic effects in all four cell lines, whereas the reverse sequence yielded a clear antagonism. 5-FU exclusively arrested cells at the G0/G1 phase, and L-OHP at the G0/G1 and G2/M phases. Apoptosis was most prominent when cells were treated simultaneously or in a sequence of L-OHP followed by 5-FU, producing apoptosis in the majority of treated cells (55.5-61.5%). In contrast, the reverse sequence yielded only 20% induction of apoptosis, the rate being not significantly different from those induced by each drug singly. Moreover, this sequence dependence was further confirmed by the experiment which compared the total number of NUGC-3 cells 7 days after these combination schedules. These findings suggest that the interaction of 5-FU and L-OHP could be highly schedule dependent, with the most efficacious interaction observed in simultaneous combination and that 5-FU followed by L-OHP would not be recommended in clinical trials for patients with advanced gastric cancer.

Abstract
To investigate the relationship between polymorphism in the 3'-untranslated region (3'-UTR) of the thymidylate synthase (TS) gene and sensitivity of gastric cancer to 5-fluorouracil (5-FU)-based chemotherapy, 106 cases of advanced gastric cancer were analyzed. All patients were treated with 5-FU-based chemotherapy; DNA from peripheral blood leukocytes was obtained before therapy. TS 3'-UTR genotypes were detected by PCR-RFLP. Polymorphism in the TS 3'-UTR can be classified into three groups according to the presence or absence of a 6 bp nucleotide fragment: the -6/-6 bp, -6/+6 bp and +6/+6 bp groups. The response rate of the -6/-6 bp and -6/+6 bp groups was found to be significantly higher than the +6/+6 bp group. These results show that the presence of the TS 3'-UTR 6 bp nucleotide fragment can be correlated with the sensitivity of gastric cancer to 5-FU-based chemotherapy, and that the TS 3'-UTR polymorphism profile can be used to guide the choice of 5-FU-based chemotherapy in advanced gastric cancer.

Abstract
OBJECTIVES A phase I trial was conducted to determine the maximally tolerated dose (MTD) and dose-limiting toxicities (DLTs) of docetaxel, capecitabine, and carboplatin for first-line treatment of patients with metastatic esophageal and gastric cancers. METHODS Twenty-eight patients were treated over 5 dose levels in a 21-day cycle. Patients received carboplatin (AUC = 2) on days 1 and 8, docetaxel (35-40 mg/m2) on days 1 and 8, and capecitabine (500-2000 mg/m2) on days 1 to 10. RESULTS There were no DLTs in the first cycle of treatment. Dose reductions were required in 10 of 15 patients at the final dose level due to neutropenia, nausea, vomiting, diarrhea, dehydration, and hand/foot syndrome following a median of 3 cycles of treatment. Therefore, escalation beyond dose level 5 was not attempted. The MTD was docetaxel, 40 mg/m2 days 1 and 8; carboplatin, AUC = 2 days 1 and 8; and capecitabine, 1500 to 2000 mg/m2 days 1 to 10 in a 21-day cycle. Ten of 25 patients who could be evaluated (40%) responded and 8 of 14 patients treated at the final dose level responded (57%). CONCLUSIONS Cumulative gastrointestinal toxicities and neutropenia were the DLTs of docetaxel, capecitabine, and carboplatin. This combination represents an easily administered, active regimen for patients with metastatic gastric and esophageal cancers. Further evaluation of this regimen is indicated.
