Functionalized polymeric patch for localized oxaliplatin delivery to treat gastric cancer. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2021; 128:112302. [PMID: 34474853 DOI: 10.1016/j.msec.2021.112302] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/19/2021] [Accepted: 07/04/2021] [Indexed: 01/20/2023]
Abstract
Localized delivery of chemotherapeutic agents allows extended drug exposure at the target site, thereby reducing systemic toxicity. We report the development of functionalized polymeric patch with unidirectional drug release to treat gastric cancer. The oxaliplatin-loaded patch was prepared by incorporating sodium carboxymethyl cellulose, hydroxypropyl cellulose and polyvinylpyrrolidone. The patch was functionalized by coating with transferrin-poly(lactic-co-glycolic acid) conjugate on one side of the patch for cancer targeting. The other side of the patch was coated with ethylcellulose (EC) to restrict the release of oxaliplatin. The physical and mechanical properties of oxaliplatin-loaded patches were characterized. Mucoadhesion studies using excised rat stomach tissue have shown that the functionalized side of the patch has significantly (p < 0.05) greater mucoadhesion strength compared with EC coated side of the patch. The in vitro and ex vivo (stomach sac and open-membrane model) studies revealed greater permeation of oxaliplatin across the stomach tissue when adhered to the functionalized and non-functionalized side of the patch compared with EC coated side. It was found that the growth inhibition with oxaliplatin solution was not significantly greater compared with corresponding concentrations of oxaliplatin-loaded patch in AGS and Caco-2 cell models. The in vivo studies were performed in mice, where indocyanine green-loaded patch encapsulated in a gelatin capsule was orally administered. The near-infrared (NIR) optical imaging revealed adherence of the patch on the mucosal side of the stomach tissue for up to 6 h. In conclusion, the functionalized polymeric patch loaded with oxaliplatin can be a potential localized delivery system to target gastric cancer.

Abstract
PURPOSE We have shown that activation of the receptor tyrosine kinase (RTK)-RAS pathway in gastric adenocarcinoma (GA) promotes acquisition of cancer stem-like cell (CSC) phenotypes including metastasis and chemotherapy resistance. Here, we evaluated the prognostic value of the CSC marker CD44 and the RTK-RAS activation marker phosphorylated MEK (p-MEK) in patients with resectable GA. METHODS CD44 and p-MEK were measured in tumors from GA patients who underwent curative-intent gastrectomy at Fujian Medical University Union Hospital (FMUUH, n = 134) and Memorial Sloan Kettering Cancer Center (MSKCC, n = 56). Overall survival (OS) was estimated by the Kaplan-Meier method, and multivariate analysis was performed by Cox proportional hazards regression modeling. RESULTS Despite multiple significant differences in clinicopathologic characteristics between the FMUUH and MSKCC cohorts, high CD44 and high p-MEK expression were both independent negative prognostic factors for OS on univariate analysis in both cohorts (p < 0.05). Both factors were also significant on multivariate analysis when the cohorts were combined (p ≤ 0.003). On subgroup analysis, the 5-year OS of patients with both high CD44 and high p-MEK was 39.5-41.6% compared with 55.4-66.4% for patients with low CD44. High CD44 expression was associated with more advanced TNM stage in the FMUUH cohort and larger tumor size and undifferentiated histology in the MSKCC cohort. High p-MEK was associated with undifferentiated histology in the FMUUH cohort and larger tumor size in the MSKCC cohort. CONCLUSIONS Increased CD44 and p-MEK expression are predictive of worse OS in GA patients. Thus, targeting the RTK-RAS pathway may benefit patients with CD44-positive, RAS-activated GA by inhibiting metastasis and reversing chemotherapy resistance.

Theranostics 2019; 9:4437-4449. [PMID: 31285771 PMCID: PMC6599661 DOI: 10.7150/thno.34953] [Citation(s) in RCA: 99] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Accepted: 05/20/2019] [Indexed: 12/12/2022] Open
Abstract
The clinical treatment of gastric cancer (GC) is hampered by the development of anticancer drug resistance and the unfavorable pharmacokinetics, off-target toxicity, and inadequate intratumoral accumulation of the current chemotherapy treatments. Ginsenosides combined with paclitaxel (PTX) have been shown to exert synergistic inhibition of human GC cell proliferation. In the present study, we developed a novel multifunctional liposome system, in which ginsenosides functioned as the chemotherapy adjuvant and membrane stabilizer. These had long blood circulation times and active targeting abilities, thus creating multifunctionality of the liposomes and facilitating drug administration to the GC cells. Methods: Three ginsenosides with different structures were used to formulate the unique nanocarrier, which was prepared using the thin-film hydration method. The stability of the ginsenoside liposomes was determined by particle size analysis using dynamic light scattering. The long circulation time of ginsenoside liposomes was compared with that of conventional liposome and polyethylene glycosylated liposomes in vivo. The active targeting effect of ginsenoside liposomes was examined with a GC xenograft model using an in vivo imaging system. To examine the antitumor activity of ginsenoside liposomes against GC, MTT, cell cycle, and apoptosis assays were performed on BGC-823 cells in vitro and PTX-loaded ginsenoside liposomes were prepared to evaluate the therapeutic efficacy on GC in vivo. Results: The ginsenosides stabilized the liposomes in a manner similar to cholesterol. We confirmed the successful delivery of the bioactive combination drugs and internalization into GC cells via analysis of the glucose-related transporter recognition and longer blood circulation time. PTX was encapsulated in different liposomal formulations for use as a combination therapy, in which ginsenosides were found to exert their inherent anticancer activity, as well as act synergistically with PTX. The combination therapy using these targeted liposomes significantly suppressed GC tumor growth and outperformed most reported PTX formulations, including Lipusu® and Abraxane®. Conclusion: We established novel ginsenoside-based liposomes as a tumor-targeting therapy, in which ginsenoside functioned not only as a chemotherapy adjuvant, but also as a functional membrane material. Ginsenoside-based liposomes offer a novel platform for anticancer drug delivery and may lead to a new era of nanocarrier treatments for cancer.

Abstract
Paclitaxel-based chemotherapy is widely used as the first-line treatment for non-small cell lung cancer (NSCLC). However, only 20%-40% of patients have shown sensitivity to paclitaxel. This study aimed to investigate whether P16 methylation could be used to predict paclitaxel chemosensitivity of NSCLC. Advanced NSCLC (N=45) were obtained from patients who were enrolled in a phase-III randomized paclitaxel-based clinical trial. Genomic DNA samples were extracted from the biopsies prior to chemotherapy. P16 methylation was detected using MethyLight. The association between P16 methylation and the sensitivity of paclitaxel in cell lines was determined by in vitro assay using a P16-specific DNA demethylase (P16-TET) and methyltransferase (P16-Dnmt). The total response rate of the low-dose paclitaxel-based chemo-radiotherapy was significantly lower in P16 methylation-positive NSCLCs than that in the P16 methylation-negative NSCLCs (2/15 vs. 16/30: adjusted OR=0.085; 95%CI, 0.012-0.579). Results revealed that P16 demethylation significantly decreased paclitaxel resistance of lung cancer H1299 cells (IC50 values decreased from 2.15 to 1.13 µg/ml, P<0.001). In contrast, P16-specific methylation by P16-Dnmt significantly increased paclitaxel resistance of lung cancer HCC827 cells and gastric cancer BGC823 cells (IC50 values increased from 18.2 to 24.0 ng/ml and 0.18 to 0.81 µg/ml, respectively; P=0.049 and <0.001, respectively). The present results suggest that P16 methylation may lead to paclitaxel resistance and be a predictor of paclitaxel chemosensitivity of NSCLC.

Abstract
OBJECTIVE A network meta-analysis was performed to compare the short-term efficacy of different chemotherapy regimens in the treatment of advanced gastric cancer. METHODS Randomized controlled trials of different chemotherapy regimens for advanced gastric cancer were included in this study. Network meta-analysis combined direct evidence and indirect evidence to evaluate the odds ratio and draw surface under the cumulative ranking curves of different chemotherapy regimens in advanced gastric cancer. RESULTS The results of surface under the cumulative ranking curves showed that S-1 and capecitabine regimens were better than fluorouracil. As for multi-drug combination regimens, the disease control rate of cisplatin + capecitabine, docetaxel + cisplatin + fluorouracil and etoposide + cisplatin + capecitabine regimens were relatively better, while fluorouracil + adriamycin + mitomycin regimen was relatively poorer when compared with cisplatin + fluorouracil regimen. Additionally, the overall response ratio of cisplatin + capecitabine, paclitaxel + fluorouracil, docetaxel + cisplatin + fluorouracil and etoposide + cisplatin + fluorouracil regimens were relatively better, while the disease control rate of fluorouracil + adriamycin + mitomycin regimen was relatively poorer when compared with cisplatin + fluorouracil regimen. Furthermore, the results of cluster analysis demonstrated that cisplatin + capecitabine, etoposide + cisplatin + capecitabine, S-1 + paclitaxel and S-1 + irinotecan chemotherapy regimens had better disease control rate and overall response ratio for advanced gastric cancer patients. CONCLUSION This network meta-analysis clearly showed that multi-drug combination chemotherapy regimens based on capecitabine and S-1 might be the best chemotherapy regimen for advanced gastric cancer.

Abstract
Background & Aims Platinum-based drugs are the most significant chemotherapy for advanced gastric cancer. The study aims to compare the efficacy and safety of oxaliplatin-based therapy versus cisplatin-based therapy in patients with advanced gastric cancer. Materials and Methods An adequate literature search in EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, American Society of Clinical Oncology (ASCO) and European Society of Medical Oncology (ESMO) was conducted. Phase II or III randomized controlled trials (RCTs) that compared effectiveness and safety between oxaliplatin-based and cisplatin-based therapy in patients with advanced gastric cancer were eligible. The primary endpoint was overall response rate (ORR), progression free survival (PFS) and overall survival (OS). The second endpoint was the adverse events. Results Five phase II or III RCTs involving a total of 2,046 patients were identified. The results showed that there were no significant difference in ORR (OR = 1.17, 95% CI = 0.98–1.40, p = 0.08, I2 = 0%), PFS (HR = 0.92, 95% CI = 0.84–1.01, p = 0.09, I2 = 0%) and OS (HR = 0.91, 95% CI = 0.82–1.01, p = 0.07, I2 = 0%) between oxaliplatin-based therapy and cisplatin-based therapy. In addition, oxaliplatin-based therapy had lower risk of neutropenia, anemia, nausea, alopecia, thromboembolism, stomatitis and creatinine increased at all grades, and neutropenia, anemia, leukopenia and alopecia at 3–4 grades than cisplatin-based therapy. However, oxaliplatin-based therapy was associated with increased risk of neurosensory toxicity and thrombocytopenia. Conclusions Our meta-analysis showed that there were no significant difference in ORR, PFS and OS between oxaliplatin-based therapy and cisplatin-based therapy. The oxaliplatin-based therapy could generally decrease the risk of adverse effects except neurosensory toxicity and thrombocytopenia.

Pharmacological inhibition of DUSP6 suppresses gastric cancer growth and metastasis and overcomes cisplatin resistance. Cancer Lett 2017; 412:243-255.

Abstract
Gastric cancer (GC) is the second cause of cancer-related death. Cisplatin (CDDP) is widely used as the standard GC treatment, but relapse and metastasis are common because of intrinsic or acquired drug resistance. The mitogen-activated protein kinase phosphatases (MAPK)-extracellular signal regulated kinases (ERK) pathway contributes to GC progression and drug resistance, but targeting the MAPK-ERK pathway is challenging in GC therapy. Here, we demonstrated that dual-specificity phosphatases 6 (DUSP6) was overexpressed in GC and predicted poor overall survival and progression-free survival. Knockdown DUSP6 inhibited GC proliferation, migration, invasion and induced apoptosis. (E/Z)-BCI hydrochloride (BCI), a DUSP6 small molecule inhibitor, increased the activity of ERK but interestingly decreased the expression of ERK response genes in BGC823, SGC7901 and CDDP-resistant SGC7901/DDP cells. BCI also caused cell death through the DNA damage response (DDR) pathway. Moreover, BCI inhibited cell proliferation, migration and invasion in a receptor-independent manner and enhanced CDDP cytotoxicity at pharmacological concentrations in the GC cells. In vivo experiments further showed that BCI enhances the antitumor effects of CDDP in cell-based xenografts and PDX models. In summary, our findings indicated that disruption of DUSP6 by BCI enhanced CDDP-induced cell death and apoptosis in GC may partly through ERK and DDR pathways. Thus, this study suggests that DUSP6 is a potential prognostic biomarker and a promising target for GC therapy.

Abstract
Bufalin has been used to treat cancer for several years. However, the molecular mechanisms for its anti-tumor function are not fully understood. This work aimed to investigate the effect of bufalin on the proliferation and apoptosis of human gastric cancer (HGC) cells and the roles of endoplasmic reticulum (ER) stress and autophagy in bufalin-induced apoptosis. HGC cell lines, SGC7901 and BGC823, were treated with different concentrations of bufalin or 80 nmol/l bufalin for 1, 2, 3 and 4 days. Cell counting kit-8 (CCK-8) assay and direct cell counting method were used to detect proliferation. Cell cycle arrest and apoptosis was detected using flow cytometry. Protein levels of caspase-3, -8, Bax/Bcl-2, Beclin-1, LC3, inositol-requiring enzyme 1 (IRE1) and C/EBP homologous protein (CHOP) were determined using western blotting. Autophagy was blocked using 3-methyladenine (3MA) or Atg5 siRNA to evaluate the effect of autophagy on bufalin-induced apoptosis. The IRE1 and CHOP were knocked down using specific siRNA to determine the pathway involved in bufalin-induced autophagy. It was found that bufalin significantly suppressed proliferation of SGC7901 and BGC823 cells and induced apoptosis in a time- and dose-dependent manner. The mechanism responsible for bufalin-induced apoptosis was the formation of ER stress via the IRE1-JNK pathway. Moreover, autophagy was activated during ER stress, and blocking autophagy significantly exacerbated bufalin-induced apoptosis. Summary: Bufalin suppressed human gastric cancer cells and induced apoptosis. The mechanism was related to ER stress formation via the IRE1-JNK pathway. Blocking autophagy exacerbated bufalin-induced apoptosis.

Abstract
BACKGROUND Several studies have reported a high rate of RHOA mutations in the Lauren diffuse-type gastric adenocarcinoma (GA) but not in intestinal-type GA. The aim of this study was to determine if RhoA activity is prognostic for overall survival (OS) in patients with resectable GA. METHODS Retrospective review was performed on a prospective database of GA patients who underwent potentially curative resection between 2003 and 2012 at a single institution. Tissue microarrays were constructed from surgical specimens and analyzed for phosphorylated RhoA, a marker of inactive RhoA signaling. OS was estimated by the Kaplan-Meier method, and multivariate analysis was performed by Cox proportional hazards regression modeling. RESULTS One hundred thirty-six patients with diffuse-type GA and 129 patients with intestinal-type GA were examined. Compared to intestinal-type GA, diffuse-type GA tumors were significantly associated with increased tumor size and advanced tumor, node, metastasis (TNM) classification system stage. In patients with diffuse-type GA, high RhoA activity was associated with significantly worse OS when compared to low RhoA activity (5-year OS 52.5 vs. 81.0 %, p = 0.017). This difference in OS was not observed in patients with intestinal-type GA (5-year OS 83.9 vs. 81.6 %, p = 0.766). On multivariate analysis of diffuse-type GA patients, high RhoA activity was an independent negative prognostic factor for OS (hazard ratio 2.38, 95 % confidence interval 1.07-5.28). CONCLUSIONS Increased RhoA activity is predictive of worse OS in patients with diffuse-type GA who undergo potentially curative surgical resection. Along with findings from genomic studies, these results suggest RhoA may be a novel therapeutic target in diffuse-type GA.

Abstract
AIM: To compare the efficacy and toxicity of modified epirubicin, oxaliplatin, and capecitabine (EOX) and irinotecan, 5-fluorouracil, and leucovorin (FOLFIRI) regimens in metastatic gastric cancer patients.
METHODS: A total of 105 patients with advanced gastric carcinoma were randomly divided into either an EOX group (n = 55) or a FOLFIRI group (n = 50). The EOX group was given epirubicin 50 mg/m2 iv on day one, oxaliplatin 85 mg/m2 iv on day 1 and capecitabine at a twice-daily dose of 625 mg/m2 po for 2 wk, which was repeated every 3 wk. Efficacy was analyzed at least every 2 cycles along with adverse reactions. Patients in the FOLFIRI group received irinotecan 180 mg/m2 on day 1, leucovorin 400 mg/m2 as two-hour infusion and 5-fluorouracil 400 mg/m2 as a bolus, on day 1 and day 2 followed by 1200 mg/(m2•d) as 22 h continuous infusion regimen every 2 wk. Efficacy was analyzed at least every 4 cycles along with adverse reactions.
RESULTS: The objective response rates (ORR) in the modified EOX group and FOLFIRI group were similar (40.0% vs 48.0%, P = 0.409). The progression-free survival (PFS) rates in the first-line modified EOX group and FOLFIRI group were 7.3 mo and 8.4 mo (P = 0.07), respectively. The PFS rates in the second-line modified EOX group and FOLFIRI group were 2.4 mo and 3.4 mo (P = 0.098), respectively. The overall survival (OS) in the modified EOX group and FOLFIRI group was 13.5 mo and 14.3 mo (P = 0.40), respectively. The risk ratio (HR) of the modified EOX group to the FOLFIRI group was 0.810 (95%CI: 0.501-1.163) and less than 1.25, which suggests that non-inferiority was established. The incidence rates of grades III-IV neutropenia, thrombocytopenia, anemia and stomatitis in the modified EOX group were significantly lower than those in the FOLFIRI group (P < 0.05). The rates of dose reduction and dose delay in the modified EOX group were significantly lower than those in the FOLFIRI group (P < 0.001).
CONCLUSION: The modified EOX regimen is safe and feasible, and has the potential to become a standard regimen against advanced gastric cancer.

Abstract
PURPOSE This study was to determine the efficacy and safety of pemetrexed based chemotherapy in treating patients with metastatic gastric cancer who failed to respond to first and (or) second line chemotherapy. PATIENTS AND METHODS Metastatic gastric cancer patients who failed first and (or) second line chemotherapy, were enrolled. All patients were recruited from Jiangsu Cancer Hospital and Research Institute, and were treated with pemetrexed 500 mg/m2 (intravenous; on day 1), and a platinum (or irinotecan) every 3 weeks until disease progression, or intolerable toxicity. Evaluation on efficacy was conducted after two cycles of chemotherapy using the Response Evaluation Criteria for Solid Tumors. Toxicity was recorded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. RESULTS From Jun 2011 to May 2013, 23 patients were enrolled. All eligible 23 patients completed at least 2 cycles of chemotherapy with pemetrexed based chemotherapy, and were evaluable. Their median age was 55 years (range 40 to 78 years). Seventeen patients were male and 6 female. Three patients (13%) achieved partial response, five patients (22%) stable, 15 patients (65%) with disease progression, and none with complete response. Grade 2 neutrophil suppression occurred in 4.3%, grade 3 in 13% of patients, and no grade 4 was reported. Thrombocytopenia was encountered as follows: 4.3% grade 2, 4.3% grade 3 and 4.3% grade 4. Incidence of anemia was 34.8% in grade 2, 8.7% grade 3 and 0% grade 4. Only 4.3% of patients required packed red blood cell infusion. Elevated transaminase were 4.3% in grade 2 and 0% in grade 3 or 4. Other toxicity included oral mucositis. CONCLUSIONS Pemetrexed based chemotherapy is mildly effective in treating patients with metastatic gastric cancer with tolerable toxicity.

Abstract
PURPOSE The current research was conducted to investigate the efficacy and safety of pemetrexed given continuously as a basement agent for first-, second- to third line chemotherapy of patients with metastatic lung adenocarcinoma. PATIENTS AND METHODS Patients with metastatic lung adenocarcinoma who were diagnosed in Jiangsu Cancer Hospital and Research Insitute, were enrolled. All received pemetrexed 500 mg/m2 (intravenous; on day 1), and another chemotherapieutic agent every 3 weeks until disease progression, or intolerable toxicity. Then the patients were changed to a second line chemotherapy that was still based on pemetrexed 500 mg/m2 and another chemotherapeutic agent differing from the first line example, until disease progression, or intolerable toxicity. When third line chemotherapy was needed, pemetrexed 500 mg/m2 and another new chemotherapeutic agent were combined until disease progression. Evaluation of efficacy was conducted after two cycles of chemotherapy using the Response Evaluation Criteria for Solid Tumors. Toxicity was recorded according to NCI Criteria for Adverse Events version 3.0. RESULTS From January 2010 to September 2013, 15 patients were enrolled. Their median age was 56 years (range 43 to 77 years). Eight patients were male and 7 female. Five patients (33.3%) achieved PR, while 6 patients (40.0%) remained stable, no CR on first line; and 1 PR (7.7%), 5 stable (38.5%) were recorded when pemetrexed was ordered in second line; 5 patients (41.7%) were stable after pemetrexed was combined in third line; no complete response was observed. Main side effects were grade 1 to 2 neutrophil suppression and thrombocytopenia. Other toxicities included elevated transaminase and oral mucositis, but no treatment related death occurred. CONCLUSIONS Pemetrexed continuously as a basement agent from first-, second- to third line chemotherapy is mildly effective in treating patients with metastatic lung adenocarcinoma with tolerable toxicity.

p16 Methylation is associated with chemosensitivity to fluorouracil in patients with advanced gastric cancer. Med Oncol 2014; 31:988. [PMID: 24816738 DOI: 10.1007/s12032-014-0988-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2014] [Accepted: 04/27/2014] [Indexed: 12/13/2022]
Abstract
No effective biomarkers have been confirmed to predict chemosensitivity for patients with gastric cancer. The purpose of this study was to investigate whether DNA methylation is associated with chemosensitivity in patients with gastric cancer. Tumors and matched non-tumor biopsy tissues collected from 134 advanced gastric cancer (AGC) patients prior to fluorouracil-based chemotherapy were retrospectively analyzed. The methylation status of p16, E-cadherin (CDH1), MGMT (O-6-methylguanine-DNA methyltransferase), and human mutL homolog 1 (hMLH1) was evaluated using a Methylight assay, and the association between p16 methylation and the sensitivity of 5-fluorouracil in cell lines was determined by in vitro assay. The methylation of p16 (17.9 vs. 0 %, P = 0.002), CDH1 (20.9 vs. 2.2 %, P < 0.001), MGMT (17.9 vs. 0 %, P = 0.052), and hMLH1 (14.9 vs. 2.2 %, P = 0.024) was more common in gastric cancer tissues (n = 134) than in non-tumor tissues (n = 46). For all patients, a reverse correlation was only found between p16 methylation and clinical response (P = 0.017), which suggested that p16 methylation might be associated with chemosensitivity of fluorouracil in gastric cancer patients. Results from in vitro experiments demonstrated that p16 methylation was closely correlated with the sensitivity of 5-fluorouracil in gastric cancer cells. The present results indicated that the methylation of p16, CDH1, MGMT, and hMLH1 was both frequent and specific in gastric cancer tissues. p16 Methylation might be used to predict chemosensitivity of fluorouracil for patients with AGC when validated in large samples in the future.

Tumour expression of leptin is associated with chemotherapy resistance and therapy-independent prognosis in gastro-oesophageal adenocarcinomas. Br J Cancer 2014; 110:1525-34. [PMID: 24569475 PMCID: PMC3960617 DOI: 10.1038/bjc.2014.45] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2013] [Revised: 12/23/2013] [Accepted: 01/08/2014] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Cytotoxic chemotherapy remains the main systemic therapy for gastro-oesophageal adenocarcinoma, but resistance to chemotherapy is common, resulting in ineffective and often toxic treatment for patients. Predictive biomarkers for chemotherapy response would increase the probability of successful therapy, but none are currently recommended for clinical use. We used global gene expression profiling of tumour biopsies to identify novel predictive biomarkers for cytotoxic chemotherapy. METHODS Tumour biopsies from patients (n=14) with TNM stage IB-IV gastro-oesophageal adenocarcinomas receiving platinum-based combination chemotherapy were used as a discovery cohort and profiled with Affymetrix ST1.0 Exon Genechips. An independent cohort of patients (n=154) treated with surgery with or without neoadjuvant platinum combination chemotherapy and gastric adenocarcinoma cell lines (n=22) were used for qualification of gene expression profiling results by immunohistochemistry. A cisplatin-resistant gastric cancer cell line, AGS Cis5, and the oesophageal adenocarcinoma cell line, OE33, were used for in vitro validation investigations. RESULTS We identified 520 genes with differential expression (Mann-Whitney U, P<0.020) between radiological responding and nonresponding patients. Gene enrichment analysis (DAVID v6.7) was used on this list of 520 genes to identify pathways associated with response and identified the adipocytokine signalling pathway, with higher leptin mRNA associated with lack of radiological response (P=0.011). Similarly, in the independent cohort (n=154), higher leptin protein expression by immunohistochemistry in the tumour cells was associated with lack of histopathological response (P=0.007). Higher leptin protein expression by immunohistochemistry was also associated with improved survival in the absence of neoadjuvant chemotherapy, and patients with low leptin protein-expressing tumours had improved survival when treated by neoadjuvant chemotherapy (P for interaction=0.038). In the gastric adenocarcinoma cell lines, higher leptin protein expression was associated with resistance to cisplatin (P=0.008), but not to oxaliplatin (P=0.988) or 5fluorouracil (P=0.636). The leptin receptor antagonist SHLA increased the sensitivity of AGS Cis5 and OE33 cell lines to cisplatin. CONCLUSIONS In gastro-oesophageal adenocarcinomas, tumour leptin expression is associated with chemoresistance but a better therapy-independent prognosis. Tumour leptin expression determined by immunohistochemistry has potential utility as a predictive marker of resistance to cytotoxic chemotherapy, and a prognostic marker independent of therapy in gastro-oesophageal adenocarcinoma. Leptin antagonists have been developed for clinical use and leptin and its associated pathways may also provide much needed novel therapeutic targets for gastro-oesophageal adenocarcinoma.

Abstract
BACKGROUND Gastric cancer remains a major health problem worldwide. Treatment of advanced gastric cancer is controversial and there is no standard regimen for first- or second-line chemotherapy (CT). This review aims to give an overview of the hot topics concerning treatment, prognostic factors and new strategies in advanced gastric cancer. MATERIAL AND METHODS Seven questions of special clinical interest have been formulated previously to the literature review. With the aim of answering each of these questions, a specific search of the relevant trials and meta-analyses published or communicated from 1990 to date was performed. RESULTS Patients treated with CT have a survival benefit over those treated with only best supportive care (BSC). Such active cytotoxic drugs as cisplatin or docetaxel and targeted agents as trastuzumab showed superiority in randomized trials. Other agents such as oxaliplatin, oral fluoropyrimidines and irinotecan showed non-inferiority or less toxic results, positioning them as valuable alternatives to classical schedules. Combination regimens seem to be an improvement over single agent therapy. However, increased toxicity of some regimens makes their general use difficult. Second-line CT is of value for selected patients with good performance status. Trastuzumab is the only targeted agent showing better survival when added to chemotherapy in HER2-driven tumors. CONCLUSIONS With the introduction of new agents, management of advanced gastric cancer has experienced important changes. First and second-line CT improve survival in patients with good performance status. Future trials should address how to better select patients for new, targeted agents, based upon validated predictive biomarkers.

Abstract
BACKGROUND Docetaxel and oxaliplatin are active agents for advanced gastric cancer (GC). The combination of these two drugs in a triweekly schedule is an active and attractive regimen for gastric cancer but with significant hematological toxicities. A multicenter phase II study was designed to establish an active regimen with good tolerability by using a weekly docetaxel-oxaliplatin (DO) combination in GC patients. METHODS Eligible patients had histologically confirmed stage IV gastric cancer without previous palliative chemotherapy; age ≥18 years; Eastern Cooperative Oncology Group (ECOG) performance status ≤2; at least one measurable lesion; and adequate hematological, renal, and liver functions. All patients received premedications with dexamethasone and 5-HT3 antagonist before the chemotherapy. Docetaxel (Taxotere®; Sanofi-Aventis) 30 mg/m(2) followed by oxaliplatin (Eloxatin®; Sanofi-Aventis) 65 mg/m(2) were administered on days 1 and 8 of each 21-day cycle. Treatment continued until disease progression, intolerable toxicity, or consent withdrawal. Toxicities were graded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC) version 3.0. Tumor responses were evaluated every 2 cycles by the Response Evaluation Criteria in Solid Tumors Guidelines. RESULTS From May 2007 to December 2008, a total of 47 patients were enrolled. There were 8 females and 39 males with a median age of 57 years (range 26-76). Forty-three patients were evaluable for response. Two patients obtained a complete response (4.7%) and 12 patients had a partial response (27.9%), with an overall response rate of 32.6% (95% confidence interval [CI] 19.1-48.5); 20 patients experienced stable disease (46.5%), and the disease progressed in 9 patients (20.9%). Median time to disease progression was 4.2 months and median overall survival was 8.3 months. All 47 patients were assessable for toxicity. Major grade 3/4 hematological toxicities were anemia (5 patients, 10.6%), neutropenia (2 patients, 4.3%), and leukopenia (1 patient, 2.1%). The most common grade 3/4 non-hematological toxicities were fatigue (3 patients, 6.4%) and aspartate aminotransferase (AST) elevation in 3 patients (6.4%). CONCLUSIONS The combination of weekly DO demonstrated a well-tolerated profile with moderate activity in the treatment of advanced gastric cancer. Further studies of the combination together with a fluoropyrimidine are warranted.

Abstract
Gastric cancer has high prevalence and high modality worldwide. For many years, few improvements in the efficacy of treatments were reported for advanced gastric cancer settings. Although a novel molecular target agent trastuzumab, in combination with chemotherapy, prolongs overall survival time in advanced gastric cancer, resistance to this drug still exists among human epidermal growth factor receptor-2 (HER2) positive patients. HER2 and erythropoietin receptor (EPOR) downstream signaling pathway have some common factors like Akt, Erk and STATs. Also there exist evidences that EPOR may express on some solid tumors and probably promote tumor progression. So it is reasonable for us to hypothesis that HER2 and EPOR may be co-expressed in the same gastric cancer cell and if so, EPOR signaling pathway may overlaps that with HER2 and promotes HER2 induced signal transduction to cell proliferation. In clinical settings, a stimulation of EPOR will play antagonistic effects on trastuzumab-induced anti-tumor activity to HER2-positive gastric cancer patients. Co-expression of EPOR and HER2 is a predictive factor for resistance of trastuzumab in gastric cancer.

Abstract
Despite the low efficacy of conventional antitumour drugs, chemotherapy remains an essential tool in controlling advanced gastric and oesophageal cancers. We aimed to provide a biological rationale based on the sorafenib-taxotere interaction for the clinical treatment of gastric cancer. In vitro experiments were performed on four human gastric cancer cell lines (GK2, AKG, KKP and NCI-N87). Cytotoxicity was evaluated by sulforhodamine B (SRB) assay, cell cycle perturbations, apoptosis and mitotic catastrophe were assessed by flow cytometric and microscopic analyses, and protein expression was studied by Western blot. In the in vivo experiments, nude mice xenografted with the most resistant line were treated with sorafenib and docetaxel singly or in association. Sorafenib inhibited cell growth (IG(50) values ranged from 3.4 to 8.1 μM) and caused down-regulation of MAP-K/ERK phosphorylation and of mcl-1 and p-bad expression after a 48-hr exposure. Apoptosis induction was associated with caspase-3 and -9 activation and mitochondrial membrane depolarization. The drug combination enhanced apoptosis (up to 80%) and produced a synergistic interaction when low doses of the taxane preceded administration of the antityrosine kinase. This synergism was probably due to the induction of an anomalous multidiploid G0-G1 peak and to consequent mitotic catastrophe, which increased sensitivity to sorafenib. Consistent with in vitro results, the docetaxel-sorafenib sequence exhibited high therapeutic efficacy in NCI-N87 mouse xenografts producing tumour weight inhibition (> 65%), tumour growth delay (up to 25 days) and increased mouse survival (30%). Our findings suggest the potential clinical usefulness of treatment with sorafenib and docetaxel for advanced gastric cancer.

Abstract
PURPOSE Optimal treatment for liver metastases from gastric cancer remains a matter of debate. The aim of our study is to evaluate the efficacy of radiofrequency ablation (RFA) for the treatment of liver-only metastases from gastric adenocarcinoma. MATERIALS AND METHODS We retrospectively reviewed medical records of 29 patients who developed liver-only metastases from gastric adenocarcinoma and subsequently underwent gastric resection and RFA (n = 20) or gastric resection and systemic chemotherapy (n = 9) between January 1995 and February 2008. Overall survival was estimated using the Kaplan-Meier method, and was compared using the log rank test to evaluate RFA efficacy. RESULTS Twenty patients who underwent RFA showed a median overall survival of 30.7 months (range: 2.9 to 90.9 months), a median progression-free survival of 6.8 months (range: 0.8 to 45.2 months), and median overall one-, three-, and five-year survival rates were 66.8%, 40.1%, and 16.1% respectively. The RFA group showed a 76% decreased death rate compared to the chemotherapy-only group (30.7 months versus 7 months, hazard ratio, 0.24; p = 0.004). Most patients tolerated RFA well, and complications were found to be minor (transient fever (20%) and/or right upper quadrant pain (25%)). One case of treatment-related death occurred due to sepsis that originated from a liver abscess at the ablation site. CONCLUSIONS The data suggest that a use of RFA as a liver-directed treatment may provide greater survival benefit than chemotherapy and is an alternative option for the treatment of liver-only metastases from gastric cancer.

Abstract
Gastric carcinoma is a common type of malignant tumors and is associated with high death rates. The pathogenesis of gastric carcinoma is still unclear, and increasing evidence shows that many factors contribute to this process. Chromokinesin KIF4 is involved in multiple critical cellular processes. Recently, it has become apparent that KIF4 plays a crucial suppressive role in tumorigenesis. However, the role of KIF4 in human gastric cancer is still unclear. In this study, we examined expression profiles of KIF4 in gastric carcinoma specimens and generated gastric cancer cells that stably express GFP-KIF4 fusion protein (designated as BGC-GFP-KIF4 cells) followed by cell proliferation, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, and soft agar colony-formation assays. Simultaneously, we further examined the capability of tumor formation of BGC-GFP-KIF4 cells in nude mice. The results showed that among 23 gastric carcinoma specimens, 13 cases (56.6%) had lower expression of KIF4 compared with corresponding adjacent tissues. In addition, there was a significant correlation between low expression of KIF4 and poor differentiation of tumor (P = 0.024). Overexpression of KIF4 in BGC cells inhibited cell proliferation in vitro, as well as their ability to form tumors in vivo. Our findings suggest that human chromokinesin KIF4 functions as an inhibitor of gastric cancer cell proliferation and might serve as a novel biological target to cure human gastric carcinoma.

Abstract
Metastatic gastric cancer remains an incurable disease, with a relative 5-year survival rate of 7%-27%. Chemotherapy, which improves overall survival (OS) and quality of life, is the main treatment option. Meta-analysis has demonstrated that the best survival results obtained in earlier randomized studies were achieved with three-drug regimens containing a fluoropyrimidine, an anthracycline, and cisplatin (ECF). Although there has been little progress in improving median OS times beyond the 9-mo plateau achievable with the standard regimens, the availability of newer agents has provided some measure of optimism. A number of new combinations incorporating docetaxel, oxaliplatin, capecitabine, and S-1 have been explored in randomized trials. Some combinations, such as epirubicin-oxaliplatin-capecitabine, have been shown to be as effective as (or perhaps more effective than) ECF, and promising early data have been derived for S-1 in combination with cisplatin. One factor that might contribute to extending median OS is the advancement whenever possible to second-line cytotoxic treatments. However, the biggest hope for significant survival advances in the near future would be the combination of new targeted biological agents with existing chemotherapy first-line regimens.

Abstract
BACKGROUND The combination of irinotecan with 5-fluorouracil demonstrates efficacy with tolerable safety in the first-line treatment of metastatic gastroesophageal cancer (mGC). This randomized phase II trial compared for the first time capecitabine with irinotecan or cisplatin in this setting. PATIENTS AND METHODS Patients were randomly assigned to receive 3-week cycles of capecitabine 1000 mg/m(2), twice daily for 14 days, with on day 1 either irinotecan 250 mg/m(2) (XI) or cisplatin 80 mg/m(2) (XP). The primary end point was overall response rate (ORR) and secondary end points included progression-free survival (PFS), overall survival (OS) and safety. RESULTS Of 118 patients recruited, 112 were eligible for safety analysis and 103 for efficacy analysis. In the XI and XP treatment arms, there were no marked differences in ORR, 37.7% versus 42.0%, and median PFS, 4.2 versus 4.8 months, although median OS was longer, 10.2 versus 7.9 months, respectively. Grade 3/4 toxicity was higher in the XP regimen for thrombocytes (18.2% versus 1.8%), nausea (23.6% versus12.3%) and vomiting (16.4% versus 1.8%) and in the XI arm for diarrhea (22.8% versus 7.3%). CONCLUSION The comparable activity and safety of the XI and XP regimens establish XI as a relevant platinum-free first-line treatment choice for patients with mGC.

Quality of life of palliative chemotherapy naive patients with advanced adenocarcinoma of the stomach or esophagogastric junction treated with irinotecan combined with 5-fluorouracil and folinic acid: results of a randomised phase III trial. Qual Life Res 2009; 18:853-61. [PMID: 19568958 PMCID: PMC2724642 DOI: 10.1007/s11136-009-9493-z] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2008] [Accepted: 05/17/2009] [Indexed: 12/26/2022]
Abstract
Purpose The quality of life (QL) of advanced gastric cancer patients receiving irinotecan, folinic acid and 5-fluorouracil (5-FU) (IF arm) or cisplatin with 5-FU (CF arm) is presented. Methods Patients with measurable or evaluable advanced gastric cancer received IF weekly for 6/7 weeks or CF q4 weeks. QL was assessed using the EORTC QLQ-C30 at baseline, subsequently every 8 weeks until progression and thereafter every 3 months until death. The QL data were analysed using several statistical methods including summary measures and pattern-mixture modelling. Results A total of 333 patients were randomised and treated (IF 170, CF 163). The time-to-progression for IF and CF was 5.0 and 4.2 months (P = 0.088), respectively. The overall compliance rates for QL questionnaire completion were 60 and 56% in the IF and CF arms, respectively. Significant treatment differences were observed for the physical functioning scale (P = 0.024), nausea\vomiting (P = 0.001) and EQ-5D thermometer (P = 0.020) in favour of the IF treatment arm. Conclusion There was a trend in favour of IF over CF in time-to-progression. The IF group also demonstrated a better safety profile than CF and a better QL on a number of multi-item scales, suggesting that IF offers an alternative first-line platinum-free treatment option for advanced gastric cancer.

Phase II study of epirubicin, oxaliplatin and docetaxel combination in metastatic gastric or gastroesophageal junction adenocarcinoma. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2009; 28:34. [PMID: 19267943 PMCID: PMC2657908 DOI: 10.1186/1756-9966-28-34] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2009] [Accepted: 03/09/2009] [Indexed: 11/26/2022]
Abstract
Background This phase II study was designed to evaluate the activity and safety of a combination of epirubicin, oxaliplatin and docetaxel in metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma. Methods Forty patients with measurable distant metastases received epirubicin 50 mg/m2, docetaxel 60 mg/m2 followed by oxaliplatin 100 mg/m2 on day 1 of each 21-day cycle. Primary end point was response rates (RR). Results All patients were evaluable. The overall RR was 47.5% (95% confidence interval (CI) 32–63). The disease control was 80%. Median time for response was 6 weeks. Median time to progression was 6.3 months (95% CI 5.4–7.2) and the median overall survival time was 12.1 months (95% CI 10.7–13.5). Grade 3/4 neutropenia occurred in 50% of patients with two episodes of febrile neutropenia (5%). Other non-hematological grade 3 toxicities included sensory neuropathy in two patiens (5%), vomiting and mucositis in two patients (5%) and diarrhea in one patient (2.5%). Conclusion The combination of epirubicin, oxaliplatin and docetaxel was found to be effective and well tolerated in patiens with metastatic gastric or GEJ adenocarcinoma and maybe an appropriate regimen to be used in the neoadjuvant setting and with molecularly targeted agents.
