Abstract
Patients with stage IV gastric cancer suffer from dismal outcomes, a challenge especially in many Asian populations and for which new therapeutic options are needed. To explore this issue, we used oncolytic reovirus in combination with currently used chemotherapeutic drugs (irinotecan, paclitaxel, and docetaxel) for the treatment of gastric and other gastrointestinal cancer cells in vitro and in a mouse model. Cell viability in vitro was quantified by WST-1 assays in human cancer cell lines treated with reovirus and/or chemotherapeutic agents. The expression of reovirus protein and caspase activity was determined by flow cytometry. For in vivo studies, athymic mice received intratumoral injections of reovirus in combination with irinotecan or paclitaxel, after which tumor size was monitored. In contrast to expectations, we found that reoviral oncolysis was only poorly correlated with Ras pathway activation. Even so, the combination of reovirus with chemotherapeutic agents showed synergistic cytopathic effects in vitro, plus enhanced reovirus replication and apoptosis. In vivo experiments showed that reovirus alone can reduce tumor size and that the combination of reovirus with chemotherapeutic agents enhances this effect. Thus, we find that oncolytic reovirus therapy is effective against gastric cancer. Moreover, the combination of reovirus and chemotherapeutic agents synergistically enhanced cytotoxicity in human gastric cancer cell lines in vitro and in vivo. Our data support the use of reovirus in combination with chemotherapy in further clinical trials, and highlight the need for better biomarkers for reoviral oncolytic responsiveness.

Abstract
Second-line chemotherapy is recommended for patients who have disease progression after first-line chemotherapy and have a good performance status. The aim of our study is thus to determine which chemotherapy regimen is more appropriate for second-line gastric cancer treatment. Patients were included if they met the following inclusion criteria: metastatic gastric adenocarcinoma pathology; no previous treatment for local gastric cancer (surgery, chemotherapy, or radiotherapy); received first-line chemotherapy for metastatic gastric cancer and had the disease progress afterward; had adequate organ functions for second-line chemotherapy; had an Eastern Cooperative Oncology Group (ECOG) score 0-2; and were HER-2 negative. The patients were examined in three groups according to the second-line chemotherapy regimen they received. These three groups were compared in terms of overall and progression-free survival. The three groups were statistically similar in overall survival, which was the primary endpoint of the study; the median overall survival was 5 months in the FOLFIRI group (n = 79), 6.5 months in the platinum-based group (n = 55), and 5.6 months in the taxane-based group (n = 40) (p = 0.554). There was no statistical difference between the groups' progression-free survival either; the median progression-free survival time was 3.43 months in the FOLFIRI group, 4 months in the platinum-based group, and 2.77 months in the taxane-based group (p = 0.546). There was no statistically significant difference between the three irinotecan-based, platinum-based, and taxane-based treatments. According to our study's results, the chemotherapy given in second-line treatment should be decided on an individual basis according to toxicity and cost.

Phytother Res 2022; 36:2449-2462. [PMID: 35234310 DOI: 10.1002/ptr.7419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 01/28/2022] [Accepted: 01/29/2022] [Indexed: 12/24/2022]
Abstract
Corilagin (CLG) is a hydrolyzable tannin and possesses various pharmacological activities. Here, we investigated the impact of CLG as an anti-tumor agent against human gastric tumor cells. We observed that CLG could cause negative regulation of JAKs-Src-STAT3/5 signaling axis in SNU-1 cells, but did not affect these pathways in SNU-16 cells. Interestingly, CLG promoted the induction of mitogen-activated protein kinases (MAPKs) signaling pathways in only SNU-16 cells, but not in the SNU-1 cells. CLG exhibited apoptotic effects that caused an increased accumulation of the cells in sub-G1 phase and caspase-3 activation in both SNU-1 and SNU-16 cell lines. We also noticed that CLG and docetaxel co-treatment could exhibit significantly enhanced apoptotic effects against SNU-1 cells. Moreover, the combinations treatment of CLG and docetaxel markedly inhibited cell growth, phosphorylation of JAK-Src-STAT3 and induced substantial apoptosis. Additionally, pharmacological inhibition of JNK, p38, and ERK substantially blocked CLG-induced activation of MAPKs, cell viability, and apoptosis, thereby implicating the pivotal role of MAPKs in the observed anti-cancer effects of CLG. Taken together, our data suggest that CLG could effectively block constitutive STAT3/5 activation in SNU-1 cells but induce sustained MAPKs activation in SNU-16 cells.

Comprehensive analysis of tumor mutation burden and immune microenvironment in gastric cancer. Biosci Rep 2021; 41:227672.

Abstract
Tumor mutation burden (TMB) was a promising marker for immunotherapy. We aimed to investigate the prognostic role of TMB and its relationship with immune cells infiltration in gastric cancer (GC). We analyzed the mutation landscape of all GC cases and TMB of each GC patient was calculated and patients were divided into TMB-high and TMB-low group. Differentially expressed genes (DEGs) between the two groups were identified and pathway analysis was performed. The immune cells infiltration in each GC patient was evaluated and Kaplan-Meier analysis was performed to investigate the prognostic role of immune cells infiltration. At last, hub immune genes were identified and a TMB prognostic risk score (TMBPRS) was constructed to predict the survival outcome of GC patients. The relationships between mutants of hub immune genes and immune infiltration level in GC was investigated. We found higher TMB was correlated with better survival outcome and female patients, patients with T1-2 and N0 had higher TMB score. Altogether 816 DEGs were harvested and pathway analysis demonstrated that patients in TMB-high group were associated with neuroactive ligand-receptor interaction, cAMP signaling pathway, calcium signaling pathway. The infiltration of activated CD4+ memory T cells, follicular helper T cells, resting NK cells, M0 and M1 macrophages and neutrophils in TMB-high group were higher compared than that in TMB-low group and high macrophage infiltration was correlated with inferior survival outcome of GC patients. Lastly, the TMBPRS was constructed and GC patients with high TMBPRS had poor prognosis.

Abstract
BACKGROUND Salvage systemic therapy has become the new standard of care in patients with advanced gastric and oesophago-gastric junction (OGJ) adenocarcinoma, following disease progression on first-line fluoropyrimidine and platinum-containing chemotherapy. Pharmacological agents proven to be effective in this setting include both chemotherapy and biological therapy, however, the consensus on the best salvage systemic therapy has not been reached. OBJECTIVES To assess the effects of systemic chemotherapy and biological therapy, either alone or in combination, on overall survival (OS) and progression-free survival (PFS) in patients with advanced gastric and OGJ adenocarcinoma, whose disease has progressed on, or relapsed after first-line fluoropyrimidine and platinum-containing chemotherapy. Adverse events (AEs), tumour response rate (TRR) and quality of life (QoL) associated with systemic chemotherapy and/or biological therapy were additionally assessed. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, trial registries and proceedings of the major oncology conferences up to October 2020. We additionally handsearched the reference lists of studies. No language restriction was applied. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing salvage systemic therapy (chemotherapy and/or biological therapy) and either another type of salvage systemic therapy, placebo, best supportive care (BSC) or no treatment in patients with gastric and OGJ adenocarcinoma refractory to first-line fluoropyrimidine and platinum-containing chemotherapy. DATA COLLECTION AND ANALYSIS Two review authors independently performed selection of eligible studies and the primary author extracted study characteristics and outcome data from included studies. We assessed the quality and risk of bias of eligible studies according to the Cochrane Handbook for Systematic Reviews of Interventions. We expressed pooled estimates of effect using hazard ratio (HR) calculated using an inverse variance random-effects model for time-to-event data, and risk ratio (RR) calculated using Mantel-Haenszel random-effects model for binary data. The certainty of evidence was graded using GRADEpro. MAIN RESULTS We identified 17 RCTs with 5110 participants for inclusion in this review. Tweenty-nine studies are ongoing and twenty studies are awaiting classification. No studies examined the following comparisons: chemotherapy combined with biological therapy versus placebo, BSC or no treatment, chemotherapy combined with biological therapy versus biological therapy, biological therapy versus biological therapy and chemotherapy combined with biological therapy versus chemotherapy combined with biological therapy. Chemotherapy versus placebo, best supportive care or no treatment Chemotherapy probably improves OS (HR = 0.66, 95% CI 0.52 to 0.83, moderate-certainty evidence) based on two studies involving 547 participants and improves PFS (HR = 0.57, 95% CI 0.47 to 0.69, high-certainty evidence) based on one study involving 507 participants over placebo and BSC. Chemotherapy probably increases serious AEs (SAEs) (RR = 1.38, 95% CI 1.20 to 1.59, moderate-certainty evidence) based on one study involving 503 participants. Biological therapy versus placebo, best supportive care or no treatment Biological therapy improves OS (HR = 0.55, 95% CI 0.41 to 0.73, high-certainty evidence) and probably improves PFS (HR = 0.33, 95% CI 0.19 to 0.57, moderate-certainty evidence) over placebo based on three studies involving 781 participants. There is currently insufficient evidence for increased SAEs from biological therapy (RR = 1.14, 95% CI 0.95 to 1.37, low-certainty evidence) based on two studies involving 638 participants. Chemotherapy versus biological therapy This comparison only considered immunotherapy. There is probably no evidence of a difference for OS (HR = 0.82, 95% CI 0.66 to 1.02, moderate-certainty evidence) between chemotherapy and immunotherapy, and immunotherapy probably reduces PFS (HR = 1.27, 95% CI 1.03 to 1.57, moderate-certainty evidence) based on one study involving 395 participants. SAEs may be less frequent with immunotherapy compared to chemotherapy (RR = 0.41, 95% CI 0.30 to 0.57, low-certainty evidence). Chemotherapy combined with biological therapy versus chemotherapy Addition of biological therapy to chemotherapy probably does not improve OS (HR = 0.93, 95% CI 0.83 to 1.04, moderate-certainty evidence) and we are uncertain whether it improves PFS (HR = 0.87, 95% CI 0.74 to 1.02, very low-certainty evidence) based on seven studies involving 2743 participants. We are similarly uncertain whether combined chemotherapy and biological therapy increases SAEs (RR = 1.17, 95% CI 0.95 to 1.44, very low-certainty evidence) based on four studies involving 1618 participants. Chemotherapy versus chemotherapy There is no evidence of a difference for OS and PFS between irinotecan and paclitaxel (HR = 1.13, 95% CI 0.86 to 1.48, low-certainty evidence for OS; HR = 1.14, 95% CI 0.88 to 1.48, low-certainty evidence for PFS) based on one study involving 219 participants. Similarly, there is no evidence to indicate improved OS and PFS from addition of another chemotherapy to docetaxel (HR = 1.05, 95% CI 0.72 to 1.54, low-certainty evidence for OS; HR = 0.75, 95% CI 0.52 to 1.09, low-certainty evidence for PFS) based on two studies involving 121 participants. Grade ≥ 3 neutropenia occurred commonly with both mono- and poly-chemotherapy except for docetaxel-S1 and EOX chemotherapy. AUTHORS' CONCLUSIONS Survival outcome of patients with advanced gastric and OGJ adenocarcinoma whose disease progressed on first-line fluoropyrimidine and platinum-containing chemotherapy can be improved by chemotherapy and biological therapy. Biological therapy, in particular, achieves this without clear increase in SAEs or QoL impairment. Whether biological therapy is preferred over chemotherapy is still unclear and there is no evidence of a difference for OS outcome, although immunotherapy may be associated with less SAEs. Addition of biological therapy to chemotherapy and poly-chemotherapy are associated with frequent treatment-related toxicity without clear survival benefit.

Abstract
Recently, the Cancer Genome Atlas and Asian Cancer Research Group propose two new classifications system of gastric cancer by using multi-platforms of molecular analyses. However, these highly complicated and cost technologies have not yet been translated into full clinical utility. In addition, the clinicians are expected to gain more guidance of treatment for different molecular subtypes. In this study, we developed a panel of gastric cancer patients in population from Southern China using commercially accessible TMA and immunohistochemical technology. A cohort of 259 GC patients was classified into 4 subtypes on the basis of expression of mismatch repair proteins (PMS2, MLH1, MSH2, and MSH6), E-cadherin and p21 protein. We observed that the subtypes presented distinct prognosis. dMMR-like subtype was associated with the best prognosis, and E-cadherin-a subtype was associated with the worst prognosis. Patients with p21-High and p21-Ligh subtypes had intermediate overall survival. In multivariate analysis, the dMMR-like subtype remained an independent prediction power for overall survival in the model. We described a molecular classification of gastric cancers using clinically applicable assay. The biological relevance of the four subtypes was illustrated by significant differences in prognosis. Our molecular classification provided an effective and inexpensive screening tool for improving prognostic models. Nevertheless, our study should be considered preliminary and carries a limited predictive value as a single-center retrospective study.

Abstract
Introduction In advanced gastric cancer, preoperative chemotherapy is associated with survival benefit. FOLFIRI has demonstrated promising results in terms of survival and tolerance, especially in patients with poor performance status. Case Presentation A 59-year-old male, diagnosed with pT4bN2M0 gastric cancer, underwent gastrointestinal anastomosis and three cycles of EOX chemotherapy. Due to disease progression, he was switched to FOLFIRI regimen. After 12 cycles, the patient received a subtotal gastrectomy and D2 lymphadenectomy. Microscopic examination achieved pCR, and the patient has been surviving 34 months without recurrence. No severe toxicities of chemotherapy were recorded. Conclusions FOLFIRI might be a safe and effective option in neoadjuvant treatment for advanced gastric cancer among patients with poor performance status or progression after first-line chemotherapy.

Abstract
The goal of this survey is to evaluate the anti-proliferative effects of the hydroalcholic extract of Blepharis persica seeds and its synergic effect on doxorubicin (DOX) in human colon cancer (HT-29) and gastric cancer cell (AGS) lines. 70% Ethanol was used for extraction of B. persica seed. Aluminum-chloride colorimetric and Folin-Ciocalteu reagent methods were used to measure total flavonoid and total phenolic contents of the extract respectively. Gas chromatography-mass spectrometry (GC-MS) analysis of the B. persica extract was performed on GC-MS equipment after silylation. HT-29, AGS, and human fibroblast (SKM) cell lines were treated by different concentration of the B. persica extract, (DOX) and the combination of extraction and DOX. The cytotoxicity was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay while the apoptosis induction was monitored using flowcytometry by annexin-V FITC/PI double-staining. The changes in expression levels of BAX and BCL-2 were determined using Real-Time RT-qPCR. GC-MS analysis of the hydroalcoholic extract from B. persica seeds revealed 24 major components. The MTT assay revealed the cytotoxicity against three cell lines and also it was shown that 125 ng/mL of DOX and 0.625 mg/mL of B. persica extract had synergistic behavior against HT29 cell line. These results showed B. persica extract induced apoptosis in AGS and HT29 cells and its extract caused dose-dependent increase in up-regulation of BAX level (p < 0.05) and down-regulation of BCL2 (p < 0.05). B. persica showed the synergistic effect in combination with DOX on HT29 cell line. These findings demonstrated a basis for further studies on the characterization and mechanistic evaluation of the bioactive compounds of B. persica extract which had antiproliferative effects on cancer cell lines.

Abstract
Introduction: People with metastatic gastric cancer (GC) have a poor prognosis. The study aims to investigate the efficacy of multi-modality treatment for patients with metastatic GC. Methods: We retrospectively identified 267 patients with stage IV gastric cancer who were treated with systemic chemotherapy: 114 received multi-modality treatments, 153 received systematic chemotherapy alone. The survival of these two groups was compared by log rank test, the independent prognostic factors were investigated using univariate and multivariate analyses. Results: The median survival of metastatic GC patients who received multi-modality treatment was significantly longer than those who received systematic chemotherapy alone (18.4 vs. 11.4 months, P < 0.001). Multivariate analysis identified tumor histologic differentiation, CA19–9 level, previous curative resection, palliative gastrectomy, and metastasectomy as independent prognostic factors for overall survival. In the multimodality treatment group, patients who received palliative gastrectomy or metastasectomy had a longer survival than those who only received intraperitoneal chemotherapy or radiotherapy (21.6 vs. 15.2 months, P = 0.014). Conclusion: Multi-modality treatments offer a survival benefit for patients with metastatic GC. Future prospective studies are needed to confirm the result.

Abstract
Gastric cancer (GC) is a complex disease linked to a series of environmental factors and unhealthy lifestyle habits, and especially to genetic alterations. GC represents the second leading cause of cancer-related deaths worldwide. Its onset is subtle, and the majority of patients are diagnosed once the cancer is already advanced. In recent years, there have been innovations in the management of advanced GC including the introduction of new classifications based on its molecular characteristics. Thanks to new technologies such as next-generation sequencing and microarray, the Cancer Genome Atlas and Asian Cancer Research Group classifications have also paved the way for precision medicine in GC, making it possible to integrate diagnostic and therapeutic methods. Among the objectives of the subdivision of GC into subtypes is to select patients in whom molecular targeted drugs can achieve the best results; many lines of research have been initiated to this end. After phase III clinical trials, trastuzumab, anti-Erb-B2 receptor tyrosine kinase 2 (commonly known as ERBB2) and ramucirumab, anti-vascular endothelial growth factor receptor 2 (commonly known as VEGFR2) monoclonal antibodies, were approved and introduced into first- and second-line therapies for patients with advanced/metastatic GC. However, the heterogeneity of this neoplasia makes the practical application of such approaches difficult. Unfortunately, scientific progress has not been matched by progress in clinical practice in terms of significant improvements in prognosis. Survival continues to be low in contrast to the reduction in deaths from many common cancers such as colorectal, lung, breast, and prostate cancers. Although several target molecules have been identified on which targeted drugs can act and novel products have been introduced into experimental therapeutic protocols, the overall approach to treating advanced stage GC has not substantially changed. Currently, surgical resection with adjuvant or neoadjuvant radiotherapy and chemotherapy are the most effective treatments for this disease. Future research should not underestimate the heterogeneity of GC when developing diagnostic and therapeutic strategies aimed toward improving patient survival.

Cycloastragenol can negate constitutive STAT3 activation and promote paclitaxel-induced apoptosis in human gastric cancer cells.

Abstract
BACKGROUND Cycloastragenol (CAG), a triterpene aglycone is commonly prescribed for treating hypertension, cardiovascular disease, diabetic nephropathy, viral hepatitis, and various inflammatory-linked diseases. HYPOTHESIS We investigated CAG for its action on signal transducer and activator of transcription 3 (STAT3) activation cascades, and its potential to sensitize gastric cancer cells to paclitaxel-induced apoptosis. METHODS The effect of CAG on STAT3 phosphorylation and other hallmarks of cancer was deciphered using diverse assays in both SNU-1 and SNU-16 cells. RESULTS We observed that CAG exhibited cytotoxic activity against SNU-1 and SNU-16 cells to a greater extent as compared to normal GES-1 cells. CAG predominantly caused negative regulation of STAT3 phosphorylation at tyrosine 705 through the abrogation of Src and Janus-activated kinases (JAK1/2) activation. We noted that CAG impaired translocation of STAT3 protein as well as its DNA binding activity. It further decreased cellular proliferation and mediated its anticancer effects predominantly by causing substantial apoptosis rather than autophagy. In addition, CAG potentiated paclitaxel-induced anti-oncogenic effects in gastric tumor cells. CONCLUSIONS Our results indicate that CAG can function to impede STAT3 activation in human gastric tumor cells and therefore it may be a suitable candidate agent for therapy of gastric cancer.

Abstract
Gastric cancer remains one of the most lethal cancers with high incidence and mortality worldwide. The majority of gastric cancer patients are those who have first been diagnosed in advanced stage, in which the standard chemo-radiotherapy produces limited benefit along with severe general toxicity, thus the demand for improved therapeutic efficacy and decreased side effects drives the development of novel therapeutic strategies. Here, a neoadjuvant chemotherapy based on Abraxane/human neutrophils (NEs) cytopharmaceuticals with radiotherapy is presented for effective cancer treatment. Human NEs, the most abundant white blood cells in peripheral blood, are developed to carry Abraxane, the commercial albumin-bound paclitaxel nanoparticle, to form cytopharmaceuticals (Abraxane/NEs) which have been confirmed to maintain the intrinsic functions of human NEs. The modest radiation is applied not only to exert tumor disruption, but also to increase the release of inflammatory factors which guide the NEs homing to the tumoral sites. These amplified inflammatory factors at tumor sites excessively activate Abraxane/NEs to form neutrophil extracellular traps, along with a burst release of Abraxane to induce superior tumor suppression. This adjuvant chemo-radiotherapy based on cytopharmaceuticals may provide new opportunities for advanced cancer treatment, which reveals the huge clinical potential of human neutrophils as drug delivery vectors.

A Phase III Study to Compare the Efficacy and Safety of Paclitaxel Versus Irinotecan in Patients with Metastatic or Recurrent Gastric Cancer Who Failed in First-line Therapy (KCSG ST10-01). Oncologist 2018; 24:18-e24. [PMID: 30126861 PMCID: PMC6324622 DOI: 10.1634/theoncologist.2018-0142] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2018] [Accepted: 06/28/2018] [Indexed: 01/13/2023] Open
Abstract
Lessons Learned. Irinotecan could not be proven noninferior to paclitaxel as a second‐line treatment for patients with metastatic or recurrent gastric cancer. The failure to demonstrate noninferiority may have been a result of insufficient patient enrollment. Both agents were tolerable but showed different toxicity profiles.
Background. This phase III study compared the efficacy and safety of paclitaxel versus irinotecan in patients with metastatic or recurrent gastric cancer (MRGC) who had experienced disease progression following first‐line chemotherapy. Methods. Patients were randomized to receive either paclitaxel (70 mg/m2; days 1, 8, 15, every 4 weeks) or irinotecan (150 mg/m2 every other week). The primary endpoint was progression‐free survival (PFS). Results. This study was stopped early due to low accrual rate. A total of 112 patients were enrolled; 54 were allocated to paclitaxel and 58 to irinotecan. Median PFS for the paclitaxel and irinotecan groups was 3.5 and 2.1 months, respectively (hazard ratio [HR], 1.27; 95% confidence interval [CI], 0.86–1.88; p = .234). Noninferiority of irinotecan to paclitaxel was not proved because the upper boundary of the 95% CI (1.88) exceeded the predefined upper margin of noninferiority (1.32). Median overall survival (OS) was 8.6 months in the paclitaxel group and 7.0 months in the irinotecan group (HR, 1.39; 95% CI, 0.91–2.11; p = .126). Among toxicities greater than or equal to grade 3, neutropenia (11.5%) was the most common, followed by peripheral neuropathy (7.7%) in the paclitaxel group, and neutropenia (34.5%) followed by nausea, vomiting, and anemia (8.6%, respectively) in the irinotecan group. Conclusion. Although paclitaxel showed numerically longer PFS and OS compared with irinotecan, this was statistically insignificant. Both irinotecan and paclitaxel are valid second‐line treatment options in MRGC.

Abstract
The adoptive transfer of cytotoxic T lymphocytes (CTLs) stimulated by specific tumor antigen peptide-pulsed dendritic cells (DCs) is one of the most promising immunotherapeutic strategies currently available for patients with gastric cancer (GC). The present case report describes a patient with chemotherapy-resistant stage IV GC with multiple bone metastases, who had been treated with antigen peptide-pulsed DC-CTLs. DCs and CTLs were transfused into the patient subcutaneously and intravenously with simultaneous oral administration of low-dose cyclophosphamide. Following 3 cycles of combination therapy, marked remission regarding the number of metastatic bone lesions was achieved, confirmed by the use of enhanced computerized tomography, computerized tomography and magnetic resonance imaging. After 1 year, 8 cycles of adoptive immunotherapy were administered, and a further decrease in the number of metastatic bone lesions was observed in addition to a marked improvement in the patient's quality of life. Therefore, personalized antigen peptide-pulsed DC-CTLs combined with oral administration of low-dose cyclophosphamide may serve as a promising anticancer therapy to eradicate tumor cells, and therefore this approach is recommended for future cases of a similar nature.

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
Palliative chemotherapy is the mainstay of treatment of advanced gastric carcinoma (GC). Monoclonal antibodies including trastuzumab, ramucirumab, and pembrolizumab have been shown to provide additional benefits. However, the clinical outcomes are often unpredictable and they can vary widely among patients. Currently, no biomarker is available for predicting treatment response in the individual patient except human epidermal growth factor receptor 2 (HER2) amplification and programmed death-ligand 1 (PD-L1) expression for effectiveness of trastuzumab and pembrolizumab, respectively. Multi-platform molecular analysis of cancer, including GC, may help identify predictive biomarkers to guide selection of therapeutic agents. Molecular classification of GC by The Cancer Genome Atlas Research Network and the Asian Cancer Research Group is expected to identify therapeutic targets and predictive biomarkers. Complementary to molecular characterization of GC is molecular profiling by expression analysis and genomic sequencing of tumor DNA. Initial analysis of patients with gastroesophageal carcinoma demonstrates that the ratio of progression-free survival (PFS) on molecular profile (MP)-based treatment to PFS on treatment prior to molecular profiling exceeds 1.3, suggesting the potential value of MP in guiding selection of individualized therapy. Future strategies aiming to integrate molecular classification and profiling of tumors with therapeutic agents for achieving the goal of personalized treatment of GC are indicated.

Abstract
Lysine acetylation has been reported to involve in the pathogenesis of multiple diseases including cancer. In our screening study to identify natural compounds with lysine acetyltransferase inhibitor (KATi) activity, oridonin was found to possess acetyltransferase-inhibitory effects on multiple acetyltransferases including P300, GCN5, Tip60, and pCAF. In gastric cancer cells, oridonin treatment inhibited cell proliferation in a concentration-dependent manner and down-regulated the expression of p53 downstream genes, whereas p53 inhibition by PFT-α reversed the antiproliferative effects of oridonin. Moreover, oridonin treatment induced cell apoptosis, increased the levels of activated caspase-3 and caspase-9, and decreased the mitochondrial membrane potential in gastric cancer cells in a concentration-dependent manner. Caspase-3 inhibition by Ac-DEVD-CHO reversed the proapoptosis effect of oridonin. In conclusion, our study identified oridonin as a novel KATi and demonstrated its tumor suppressive effects in gastric cancer cells at least partially through p53-and caspase-3-mediated mechanisms.

Abstract
Background This study evaluated the safety and efficacy of nab-paclitaxel as second-line treatment in patients with advanced gastric adenocarcinoma. Methods Thirty-nine pretreated patients [33 with taxane-based regimens (docetaxel, cisplatin, and fluorouracil)] and 6 with combination of fluoropyrimidines plus cisplatin with locally advanced inoperable and metastatic gastric and gastroesophageal junction adenocarcinoma were treated with weekly nab-paclitaxel (150 mg/m2 d1, d8, d15 in cycles of 28 days). Results Partial response (PR) was documented in nine patients (23.1%; 95% confidence interval 10.1-37.2%), stable disease (SD) in 11 (28.2%) and disease progression in 18 (46.2%). The disease control rate (SD + PR + complete response) was 51.3%. Grade 3 and 4 neutropenia occurred in 10.2% and 5.1% of patients, respectively; grade 3 anemia in 5.1%; grade 3 neurotoxicity in 5.1%; and grade 2 pain in 5.1%. The median progression-free survival was 3.0 months (range 0.3-13.6) and the median overall survival 6.8 months (range 0.3-22). Conclusion Nab-paclitaxel as second-line treatment in locally advanced inoperable or metastatic gastric and gastroesophageal junction carcinoma is an active chemotherapy regimen with a manageable toxicity profile and merits further evaluation.

Abstract
BACKGROUND Second-line therapy has consistently demonstrated survival benefit if compared with best supportive care; however, there is limited evidence whether further lines of treatment may improve the prognosis of advanced gastric cancer (AGC) patients. MATERIALS AND METHODS Starting from a real-world cohort of 868 AGC patients, we retrospectively analyzed baseline parameters, tumor characteristics, and treatment data of those treated with at least three lines. Categorical features were described through cross-tables and chi-square test. We explored the impact of treatment intensity and progression-free survival (PFS) experienced in previous lines on PFS and overall survival in third-line by uni- and multivariate Cox regression models and described by Kaplan-Meier estimator plot with log-rank test. RESULTS Overall, 300 patients were included in the analysis. The most common site of primary tumor was gastric body; 45.3% of cancers had an intestinal histotype, 14% were human epidermal growth receptor 2 positive. In third-line, 45.7% of patients received a single-agent chemotherapy, 49.7% a combination regimen. Patients who had experienced a first-line PFS ≥6.9 months had a better prognosis compared with those who had achieved a shorter one. Consistently, a second-line PFS ≥3.5 months positively influenced the prognosis. Patients receiving a third-line combination regimen had better outcomes compared with those treated with a single-agent chemotherapy. CONCLUSION Our real-world study confirms that selected AGC patients may receive third-line treatment. Longer PFS in previous lines or a more intense third-line treatment positively influenced prognosis. Further efforts are warranted to define the best therapeutic sequences, and to identify the optimal candidate for treatment beyond second-line. IMPLICATIONS FOR PRACTICE The benefit of third-line treatment to advanced gastric cancer patients is controversial. This study depicts a real scenario of the clinical practice in Italy, confirming that a non-negligible proportion of patients receive a third-line therapy. Longer progression-free survival in previous treatment lines or higher third-line treatment intensity positively influenced prognosis. Including a large number of real-world patients, this study provides information on third-line treatment from the daily clinical practice; moreover, its results help in defining the best therapeutic sequence and offer some hints to select the optimal candidate for treatment beyond second-line.

Mol Med Rep 2017; 15:2633-2642. [PMID: 28447717 DOI: 10.3892/mmr.2017.6300] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Accepted: 09/28/2016] [Indexed: 11/06/2022] Open
Abstract
Macroautophagy, which will hereafter be referred to as autophagy, is an evolutionarily conserved process, during which cells recycle and remove damaged organelles and proteins in response to cellular stress. However, the mechanisms underlying the regulation of autophagy remain to be fully elucidated. The present study demonstrated that knockdown of zinc finger protein like 1 (ZFPL1) induces autophagy and increases autophagic cell death in NCI‑N87 and BGC‑823 human gastric carcinoma cell lines. To examine the role of ZFPL1 in gastric carcinoma cells, ZFPL1 expression was downregulated by lentiviral infection. Zinc finger domain‑FLAG was used to compete with ZFPL1 for golgin A2/GM130 binding. Autophagy was analyzed by red fluorescent protein‑microtubule‑associated protein 1A/1B‑light chain 3 (LC3) puncta, LC3I to LC3II conversion, and p62 expression. The results demonstrated that knockdown of ZFPL1 was able to significantly increase cell death rate. However, ZFPL1 knockdown exerted almost no effect on the expression of apoptosis‑associated markers, including B cell lymphoma 2 (Bcl‑2), Bcl‑x, Bcl‑2‑associated X protein, BH3 interacting domain death agonist, p53, and the classical caspase family members, caspase‑3, caspase‑8 and caspase‑9. An endogenous ZFPL1‑GM130 association was identified in NCI‑N87 cells and BGC‑823 cells by co‑immunoprecipitation. Furthermore, cell death was restricted following treatment of ZFPL1 knockdown cells with an autophagy inhibitor. Therefore, knockdown of ZFPL1 expression may induce cell death via autophagy, rather than apoptosis. These results suggest that ZFPL1 may serve an important role in regulating autophagy in NCI‑N87 and BGC‑823 cells.

A polymorphism in the promoter region of PD-L1 serves as a binding-site for SP1 and is associated with PD-L1 overexpression and increased occurrence of gastric cancer.

Abstract
PD-L1 is a member of the B7 family co-inhibitory molecules and plays a critical role in tumor immune escape. In this study, we found a polymorphism rs10815225 in the PD-L1 promoter region was significantly associated with the occurrence of gastric cancer. The GG homozygous frequency was higher in the cancer patients than that in the precancerous lesions, which was higher than that in the health controls. This polymorphism locates in the binding-site of Sp1 transcription factor (SP1). The expression level of PD-L1 mRNA in the GG homozygous cancer patients was apparently higher than that in the GC heterozygotes. Luciferase reporter results showed that SP1 bonded to rs10815225 G-allelic PD-L1 promoter instead of C-allelic. Upregulation and knockdown of SP1 resulted in elevation and attenuation of PD-L1 in SGC-7901 cells, respectively. The chromatin immunoprecipitation results further confirmed the binding of SP1 to the promoter of PD-L1. Additionally, rs10815225 was found to be in disequilibrium with a functional polymorphism rs4143815 in the PD-L1 3'-UTR, and the haplotypes of these two polymorphisms were also markedly related to gastric cancer risk. These results revealed a novel mechanism underlying genetic polymorphisms influencing PD-L1 expression modify gastric cancer susceptibility.

Melatonin treatment induces apoptosis through regulating the nuclear factor-κB and mitogen-activated protein kinase signaling pathways in human gastric cancer SGC7901 cells.

Abstract
Melatonin, which is synthesized by the pineal gland and released into the blood, exhibits antitumor properties. However, the mechanisms underlying these effects, particularly in stomach cancer, remain unknown. In the present study, the effect of melatonin on the nuclear factor (NF)-κB signaling pathway and the mitogen-activated protein kinase signaling pathway, involving p38 and c-Jun-N-terminal kinase (JNK), were investigated in SGC7901 gastric cancer cells. In addition, the effect of melatonin on the survival, migration and apoptosis of these cells was investigated in vitro in order to evaluate the use of melatonin for the treatment of gastric cancer. The results of the present study revealed that melatonin decreased the viability and migration of SGC7901 cells. Furthermore, melatonin induced apoptosis. Melatonin was identified to elevate the expression levels of phosphorylated (p)-p38 and p-JNK protein, and decrease the expression level of nucleic p-p65. These results suggest that the protein levels of p65, p38 and JNK are associated with the survival of SGC7901 cells following treatment with melatonin. The optimal concentration of melatonin was demonstrated to be 2 mM, which significantly induced apoptosis following a 24 h treatment period. These findings suggest that conflicting growth signals in cells may inhibit the efficacy of melatonin in the treatment of gastric cancer. Therefore, adjunct therapy would be required to improve the efficacy of melatonin in the treatment of cancer.

Abstract
Predictive biomarkers based individualized chemotherapy can improve efficacy. However, for those advanced patients, it may be impossible to obtain the tissues from operation. Tissues from biopsy may not be always enough for gene detection. Thus, biomarker from blood could be a non-invasive and useful tool to provide real-time information in the procedure of treatment. To further understand the role of plasma mRNA in chemo-efficiency prediction, several mRNA expression levels were assessed in plasma and paired tumor tissues from 133 locally advanced gastric cancer patients (stage III), and mRNA levels were correlated with chemosensitivity to docetaxel, pemetrexed, platinum, and irinotecan. mRNA expression level in 64 advanced gastric cancer patients (stage IV) was also examined (55 in test group, and 9 in control), and chemotherapy in the test group were given according to the plasma gene detection. As a result, in the 133 patients with locally advanced gastric cancer (Stage III), correlations were observed between the mRNA expression of plasma/tumor BRCA1 levels and docetaxel sensitivity (P<0.001), plasma/tumor TS and pemetrexed sensitivity (P<0.001), plasma/tumor BRCA1 and platinum sensitivity (plasma, P=0.016; tumor, P<0.001), and plasma/tumor TOPO1 and irinotecan sensitivity (plasma, P=0.015; tumor, P=0.011). Among another 64 patients with advanced cancer (Stage IV), the median OS of test group was 15.5m (95% CI=10.1 to 20.9m), the PFS was 9.1m (95% CI=8.0 to 10.2m), which were significant longer than the control (P=0.047 for OS, P=0.038 for PFS). The mortality risk was higher in the control than patients treated according to the plasma gene detection (HR in the control=2.34, 95% CI=0.93 to 5.88, P=0.071). Plasma mRNA as liquid biopsy could be ideal recourse for examination to predict chemo-sensitivity in gastric cancer.

Abstract
Chemotherapy drugs, including 5-fluorouracil (5-FU), oxaliplatin and docetaxel, are commonly used in the treatment of gastric cancer (GC). Apoptosis-relevant genes may be associated with drug resistance. In the present study, the messenger RNA (mRNA) expression levels of B-cell lymphoma 2 interacting mediator of cell death (BIM), astrocyte elevated gene-1 (AEG-1) and AXL receptor tyrosine kinase (AXL) were investigated in 131 advanced GC samples, and the expression levels of these genes were correlated with patients' overall survival (OS). All 131 patients received first-line FOLFOX combination chemotherapy with folinic acid and 5-FU, in which 56 patients were further treated with second-line docetaxel-based chemotherapy. A correlation between the mRNA expression levels of BIM and AEG-1 was observed (rs=0.30; P=0.002). There was no association between the mRNA expression levels of any of the individual genes analyzed and OS in patients only receiving first-line FOLFOX chemotherapy. In a subgroup of patients receiving docetaxel-based second-line chemotherapy, those with high or intermediate levels of BIM exhibited a median OS of 18.2 months [95% confidence interval (CI), 12.8-23.6], compared with 9.6 months (95% CI, 8.9-10.3) in patients with low BIM levels (P=0.008). However, there was no correlation between the mRNA expression levels of AEG-1 or AXL and OS. The risk of mortality was higher in patients with low BIM mRNA levels than in those with high or intermediate BIM mRNA levels (hazard ratio, 2.61; 95% CI, 1.21-5.62; P=0.010). Therefore, BIM may be considered as a biomarker to identify whether patients could benefit from docetaxel-based second-line chemotherapy in GC.

Abstract
Although rapid advances in treatment options have improved the prognosis of advanced gastric cancer (AGC), it remains a major public health problem and the second leading cause of cancer-related deaths in the world. Taxanes (paclitaxel and docetaxel) are microtubule stabilizing agents that inhibit the process of cell division, and have shown antitumor activity in the treatment of AGC as a single or combination chemotherapy. Accordingly, this review focuses on the efficacy and tolerability of taxanes in the first- or second-line chemotherapy setting for AGC.

Abstract
BACKGROUND/AIMS The purpose of this study was to investigate the efficacy and safety of irinotecan based FOLFIRI chemotherapy as a second-line treatment after failure of FOLFOX-4 chemotherapy in patients with advanced gastric cancer. METHODS Fifty-two patients who were pathologically diagnosed with unresectable gastric cancer and received FOLFIRI chemotherapy after failure of FOLFOX-4 chemotherapy between September 2005 and February 2012 were enrolled in this study. Data were collected by retrospectively reviewing the medical records. The response to chemotherapy was assessed every 3 cycles by World Health Organization criteria and long term survival was analyzed. The toxicities were evaluated for every course of chemotherapy according to National Cancer Institution (NCI) toxicity criteria version 3.0. RESULTS Median age of the patients was 57 years. Median overall survival (OS) and time to progression (TTP) were 7.8 and 5 months, respectively. The number of patients showing complete remission, partial remission, stable disease, and progressive disease were 0 (0.0%), 9 (17.3%), 30 (57.7%), and 13 (25.0%), respectively. The overall response rate was 17.3%. During a total of 345 cycles, anemia worse than NCI toxicity grade 3 occurred in 2.9%, leukopenia in 20.3%, neutropenia in 12.2%, and thrombocytopenia in 1.5%. Patients with less organ involvement by metastasis, less than 34 U/mL of CA 19-9 and good responsiveness to third cycle of second line chemotherapy were associated with longer OS and TTP. CONCLUSIONS FOLFIRI chemotherapy has a modest efficacy with acceptable toxicities in patients with advanced gastric cancer as a second-line treatment. Further well-controlled studies are needed to elucidate the efficacy of FOLFIRI chemotherapy as second-line treatment in patients with advanced stomach cancer.

Cytoplasmic Drosha Is Aberrant in Precancerous Lesions of Gastric Carcinoma and Its Loss Predicts Worse Outcome for Gastric Cancer Patients. Dig Dis Sci 2016; 61:1080-90. [PMID: 26694172 DOI: 10.1007/s10620-015-3986-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2015] [Accepted: 11/30/2015] [Indexed: 01/13/2023]
Abstract
BACKGROUND The nuclear localization of Drosha is critical for its function as a microRNA maturation regulator. Dephosphorylation of Drosha at serine 300 and serine 302 disrupts its nuclear localization, and aberrant distribution of Drosha has been detected in some tumors. AIMS The purpose of the present study was to assess cytoplasmic/nuclear Drosha expression in gastric cancer carcinogenesis and progression. METHODS Drosha expression and its subcellular location was investigated by immunohistochemical staining of a set of tissue microarrays composed of normal adjacent tissues (374), chronic gastritis (137), precancerous lesions (94), and gastric adenocarcinoma (829) samples, and in gastric cancer cell lines with varying differentiation by immunofluorescence and western blot assay. RESULTS Gradual loss of cytoplasmic Drosha was accompanied by tumor progression in both gastric cancer tissues and cell lines, and was inversely associated with tumor volume (P = 0.002), tumor grade (P < 0.001), tumor stage (P = 0.018), and distant metastasis (P = 0.026). Aberrant high levels of cytoplasmic Drosha were apparent in intestinal metaplasia and dysplasia tissues. The levels of nuclear Drosha were sharply decreased in chronic gastritis and maintained through precancerous lesions to gastric cancer. High levels of cytoplasmic Drosha predicted longer survival (LR = 7.088, P = 0.008) in gastric cancer patients. CONCLUSIONS Our data provide novel insights into gastric cancer that cytoplasmic Drosha potentially plays a role in preventing carcinogenesis and tumor progression, and may be an independent predictor of patient outcome.

Abstract
Several cytotoxic agents, including fluoropyrimidines, platinums, taxanes and irinotecan, are effective in the treatment of advanced gastric cancer (AGC). However, the effect of the availability of cytotoxic agents on survival has not yet been evaluated. Therefore, the present study assessed the impact of the availability of active cytotoxic agents on the survival of patients with AGC. The records of 216 patients with newly diagnosed AGC that were treated with palliative chemotherapy between March 2002 and November 2012 at Chungbuk National University Hospital were reviewed. For the present study, the patients were divided according to the availability of active cytotoxic agents over the course of treatment: Group 1 received fluoropyrimidine and platinum; group 2 received fluoropyrimidine, platinum and taxane or irinotecan; and group 3 received fluoropyrimidine, platinum, taxane and irinotecan. The median overall survival times for groups 1, 2 and 3 were 6.3, 9.9 and 14.3 months, respectively (P<0.0001). Multivariate analysis revealed that the Eastern Cooperative Oncology Group (ECOG) performance status and the availability of active cytotoxic agents were independent prognostic factors, as the hazard ratios for mortality were 3.25 for patients with an ECOG performance status of 2-3 [95% confidence interval (CI), 1.99-5.30; P<0.0001], 0.58 for patients in group 2 (95% CI, 0.42-0.80; P=0.0009), and 0.40 for patients in group 3 (95% CI, 0.28-0.58; P<0.0001). The present study reveals that the availability of active cytotoxic agents is associated with an improved survival time in patients with AGC.

Abstract
The FDA approved ramucirumab (CYRAMZA; Eli Lilly and Company) for previously treated patients with advanced or metastatic gastric or gastroesophageal junction adenocarcinoma initially as monotherapy (April 21, 2014) and subsequently as combination therapy with paclitaxel (November 5, 2014). In the monotherapy trial, 355 patients in the indicated population were randomly allocated (2:1) to receive ramucirumab or placebo, 8 mg/kg intravenously every 2 weeks. In the combination trial, 665 patients were randomly allocated (1:1) to receive ramucirumab or placebo, 8 mg/kg intravenously every 2 weeks, in combination with paclitaxel, 80 mg/m(2) on days 1, 8, and 15 of 28-day cycles. Overall survival (OS) was increased in patients who received ramucirumab in both the monotherapy [HR, 0.78; 95% confidence interval (CI), 0.60-0.998; log rank P = 0.047] and combination trials (HR, 0.81; 95% CI, 0.68-0.96; P = 0.017). The most common adverse reactions were hypertension and diarrhea in the monotherapy trial and fatigue, neutropenia, diarrhea, and epistaxis in the combination trial. Because of concerns about the robustness of the monotherapy trial results, FDA approved the original application after receiving the results of the combination trial confirming the OS effect. Based on exploratory exposure-response analyses, there is residual uncertainty regarding the optimal dose of ramucirumab.

Abstract
Adenocarcinomas of the esophagus and stomach are a major cause of cancer-related morbidity and mortality worldwide. For patients with advanced disease, first-line chemotherapy with platinum-fluoropyrimidine combinations prolongs survival, but inevitably the disease progresses with a median progression-free survival of approximately 6 months. At the time of progression, approximately 40-50% of patients remain fit and eligible for second-line treatment. Docetaxel has been extensively studied in this chemorefractory setting, mostly in small single arm studies, either as a single agent or in combination with platinum agents, fluoropyrimidines or anthracyclines. However, two randomized controlled trials published since 2012 have convincingly shown that treatment with docetaxel modestly prolongs survival compared with best supportive care alone. Moreover, treatment with docetaxel is associated with relief from cancer-related constitutional and gastrointestinal symptoms with manageable, predominantly haematological, toxicity. Therefore, it represents a valuable treatment option for patients with relapsed esophagogastric cancer. Nevertheless, in view of the short survival time for the majority of these patients, further research is necessary to identify, on the one hand, combinations with targeted agents that will further improve outcomes and, on the other, biomarkers that will allow selection of those patients most likely to benefit.

Abstract
Systemic activation of hemostasis and thrombosis has been implicated in tumor progression and metastasis. D-dimer has been used as an indicator for the thrombosis. Here, we investigated the role of the activation of coagulation in patients with metastatic gastric cancer by measuring D-dimer level.We conducted an observation study of 46 metastatic gastric cancer patients who received palliative chemotherapy (CTx). D-dimer levels were assessed before CTx and at the first response evaluation after CTx.The overall survival (OS) of patients with pretreatment D-dimer levels <1.5 μg/mL was significantly longer than that of patients with D-dimer levels ≥1.5 μg/mL (22.0 vs 7.9 months, P = 0.019). At the first response evaluation, the mean level of D-dimer was significantly decreased by 2.11 μg/mL in patients either with partial response or stable disease (P = 0.011) whereas the mean level of D-dimer, although the difference did not reach statistical significance, was increased by 2.46 μg/mL in patients with progressive disease. In addition, the OS of patients with D-dimer levels <1.0 μg/mL at the first response evaluation was significantly longer than that of patients with D-dimer levels ≥1.0 μg/mL (22.0 vs 7.0 months, P = 0.009). The lower D-dimer levels (<1.0 μg/mL) at the first response evaluation after CTx was independent predictive factor for better survival in multivariate analysis (P = 0.037).This study suggests that D-dimer levels may serve as a biomarker for response to CTx and OS in patients with metastatic gastric cancer.

Abstract
Ramucirumab is a fully humanized monoclonal antibody targeting the extracellular domain of the VEGF receptor 2. It prevents ligand binding to VEGF receptor 2 and receptor-mediated pathway activation in endothelial cells. After promising Phase I trial results in a variety of tumor types, two pivotal placebo-controlled Phase III trials conducted in patients with pretreated metastatic esophagogastric adenocarcinoma demonstrated significant clinical activity regarding the prolongation of overall survival both as monotherapy (REGARD study) and in combination with paclitaxel (RAINBOW study). Currently, ramucirumab is being investigated in the first-line treatment of esophagogastric adenocarcinoma in combination with capecitabine and cisplatin in a Phase III trial (RAINFALL).

Survival prolongation after treatment failure of first-line chemotherapy in patients with advanced gastric cancer: combined analysis of the Japan Clinical Oncology group trials JCOG9205 and JCOG9912. Gastric Cancer 2015; 17:522-8. [PMID: 24162387 DOI: 10.1007/s10120-013-0309-z] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2013] [Accepted: 09/26/2013] [Indexed: 02/07/2023]
Abstract
BACKGROUND Two randomized phase III trials of first-line chemotherapy for advanced gastric cancer (JCOG9205 and JCOG9912) conducted by the Japan Clinical Oncology Group used 5-fluorouracil continuous infusion (5-FUci) as the control arm. New active agents (e.g., S-1, irinotecan, and taxanes) were introduced as second-line chemotherapy in the late 1990s after JCOG9205. This combined analysis evaluated whether patients in the 5-FUci arm of JCOG9912 exhibited better survival after adjusting for baseline factors and also investigated the cause of survival prolongation. PATIENTS AND METHODS The subjects were patients assigned to the 5-FUci arms who met the eligibility criteria of both JCOG9205 and JCOG9912. Overall survival (OS), time to treatment failure (TTF), and survival after treatment failure in the first-line chemotherapy (OS-TTF) were compared after adjusting baseline characteristics using the Cox proportional hazard model. Second-line chemotherapy details were also reviewed. RESULTS The combined analysis included 89 and 230 patients in JCOG9205 and JCOG9912, respectively. After adjusting baseline characteristics, TTF was similar between groups (HR 0.95; 95 % CI, 0.73-1.26). However, both OS (HR, 0.74; 95 % CI, 0.56-0.99) and OS-TTF (HR, 0.76; 95 % CI, 0.57-1.01) were longer in JCOG9912. More patients in JCOG9912 received second-line chemotherapy (83 vs. 52 %) with new drugs (77 vs. 10 %) than in JCOG9205. OS-TTF was substantially prolonged in patients who received second-line chemotherapy (HR, 0.66; 95 % CI, 0.46-0.95). CONCLUSION OS and OS-TTF were longer in JCOG9912 than JCOG9205. Second-line chemotherapy with new drugs is a potential reason for the observed prolongation of survival.

Abstract
BACKGROUND We wished to evaluate the impact of S-1 combined with oxaliplatin (SOX regimen) as neoadjuvant chemotherapy on surgical outcomes after gastrectomy with D2 lymphadenectomy. METHODS From February 2012 to September 2013, 170 patients with American Joint Committee on Cancer (AJCC) stage II-III gastric cancer were assessed retrospectively. Eighty patients underwent neoadjuvant chemotherapy before radical gastrectomy, and 90 patients received surgical treatment with adjuvant chemotherapy. Patients received S-1 (80 mg/m(2)/day; days 1-14) and oxaliplatin (130 mg/m(2); day 1) as neoadjuvant or adjuvant chemotherapy, and this schedule was repeated every 3 weeks. Gastrectomy with D2 lymphadenectomy was standard therapy for each patient. Surgical outcomes between the two groups were analyzed statistically. RESULTS There was no significant difference in the total prevalence of complications between neoadjuvant and adjuvant groups (18.8% vs. 22.2%, P = 0.704). The most common postoperative complications were surgical site infection (6.5%) and gastrointestinal motility disorders (3.5%). The clinical response rate was 68.8%, and ten patients (12.5%) had a pathological complete response after neoadjuvant chemotherapy. The SOX regimen as neoadjuvant chemotherapy for AJCC stage II/III gastric cancer can be effective without increasing the risk of postoperative complications. CONCLUSIONS The SOX regimen could be a neoadjuvant chemotherapy for advanced gastric cancer worldwide in the future.

Abstract
OBJECTIVE Assess the usefulness of second-course ophthalmic artery chemosurgery (OAC) for patients with intraocular retinoblastoma that recurred after prior OAC. This study evaluated the efficacy and toxicity of second-course OAC. DESIGN Single-arm retrospective study of 29 eyes of 30 patients treated with second-course OAC at Memorial Sloan Kettering Cancer Center between May 2006 and July 2013, with a median follow-up of 25.9 months. PARTICIPANTS Retinoblastoma patients who underwent a course of OAC, with a minimum of 2 months of progression-free follow-up at monthly examinations, but who subsequently received additional OAC for recurrent tumor. METHODS To determine efficacy, Kaplan-Meier survival estimates were generated and the Mantel-Cox test was used to compare curves. To determine toxicity, electroretinography (ERG) amplitudes were measured in response to 30-Hz photopic flicker stimulation before and after OAC treatment; systemic adverse events were graded according to the Common Terminology Criteria for Adverse Events version 4.0 (CTCAE 4.0). MAIN OUTCOME MEASURES For efficacy, ocular progression-free survival, ocular event-free survival (e.g., enucleation, external-beam radiation, or intravitreal melphalan), and ocular survival. For toxicity, peak-to-peak comparisons between ERG studies before and after OAC treatment and CTCAE 4.0-graded systemic adverse events. RESULTS Fifty percent of all recurrences were within 4.4 months and 90% were within 16 months of completion of the first course of OAC. The 2-year Kaplan-Meier ocular survival, event-free survival, and progression-free survival estimates after second-course OAC were 82.8% (95% confidence interval [CI], 60.1%-93.2%), 57.3% (95% CI, 36.1%-73.7%), and 26.5% (95% CI, 11.0%-45.0%), respectively. All eyes without vitreous seeding were progression free, whereas eyes with vitreous seeding were associated significantly with worse ocular survival after second-course OAC (P = 0.03). After second-course OAC, 90% of eyes had stable or improved ERG responses. Of all evaluable cases, there was no increased risk of systemic toxicity during the second course compared with the initial course of OAC. CONCLUSIONS Retinoblastoma eyes requiring second-course OAC after initial OAC treatment have good salvage rates, and the treatment has an acceptable ocular and systemic toxicity profile. However, these eyes often require additional (third- or fourth-course) OAC or other treatment methods because of progression of disease after second-line OAC, particularly if vitreous seeds are present at the time of initial OAC failure.

Pemetrexed for previously treated patients with metastatic gastric cancer: a prospective phase II study. Br J Cancer 2014; 112:266-70. [PMID: 25474247 PMCID: PMC4453460 DOI: 10.1038/bjc.2014.607] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2014] [Revised: 10/12/2014] [Accepted: 11/06/2014] [Indexed: 02/08/2023] Open
Abstract
Background: Gastric cancer is one of the leading causes of cancer-related death worldwide. There were debates on the value of the second-line and beyond chemotherapy by the time we designed this trial. So we designed this phase II trial to assess the efficacy and safety of pemetrexed in patients with pretreated metastatic gastric cancer. Methods: Thirty-four patients with pretreated metastatic gastric cancer were enroled in the study. Patients received pemetrexed 500 mg m−2 every 21 days until the presence of progressive disease (PD) or unacceptable toxicity. Results: A total of 34 patients were enroled in the study; 34 were eligible for toxicity and 30 for response. The response rate was 13.3%, 13.3% patients achieved a partial response, 50.0% achieved stable disease and 36.7% had a PD as the best response. The median overall survival time and median progression-free survival time was 6.4 months (95% confidence interval (CI) 5.8–9.5 months) and 2.2 months (95% CI 2.0–5.5 months), respectively. Most haematologic and non-haematologic toxicity were grade 1/2. Grade 3/4 toxicity included fatigue, neutropenia, thrombocytopenia, weight loss, anorexia and transaminase elevation. Conclusions: The monochemotherapy of pemetrexed is active and well tolerated when used in previously treated patients with metastatic gastric cancer.

Oncolytic reovirus combined with trastuzumab enhances antitumor efficacy through TRAIL signaling in human HER2-positive gastric cancer cells. Cancer Lett 2014; 356:846-54. [PMID: 25444894 DOI: 10.1016/j.canlet.2014.10.046] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2014] [Revised: 10/30/2014] [Accepted: 10/30/2014] [Indexed: 12/20/2022]
Abstract
The human epidermal growth factor receptor 2 (HER2)-targeting agent, trastuzumab, is effective for HER2-overexpressing gastric cancer therapy. As oncolytic reovirus is currently undergoing clinical trials internationally, we wanted to explore whether combination therapy using trastuzumab and reovirus might provide a novel, more effective therapeutic option for gastric cancer. Cell proliferation and cell apoptosis were examined in vitro, while molecular analysis of pathways responsible for cell damage was examined using polymerase chain reaction array. Activation of the proteins related to apoptosis, cell growth and survival was detected by Western blotting. Mouse tumor xenograft models were used to examine antitumor activity in vivo. Reovirus sensitized HER2-overexpressing gastric cancer cells to undergo apoptosis. Both in vitro and in vivo studies provided evidence that the combination therapy is a more powerful modality against HER2-overexpressing gastric cancer cells than treatment using a single agent. Molecular analysis indicated that combination therapy induced significantly higher levels of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in cancer cells. Antibody against TRAIL strongly inhibited cell toxicity caused by the combined treatment. These data suggest that reovirus may augment trastuzumab-induced cytotoxicity in gastric cancer cells.

Phase I trials in patients with relapsed, advanced upper gastrointestinal carcinomas: experience in a specialist unit. Gastric Cancer 2014; 17:621-629. [PMID: 24445485 PMCID: PMC4881817 DOI: 10.1007/s10120-013-0328-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2013] [Accepted: 12/16/2013] [Indexed: 02/07/2023]
Abstract
BACKGROUND Conventional therapeutic options for patients with advanced upper gastrointestinal cancers (UGIC) are limited. Following first-line treatments, some patients are offered experimental therapies, including participation in Phase I trials. This study aims to describe the experience of UGIC patients treated in a dedicated Phase I unit. METHODS Patient, tumour and treatment characteristics, and clinical outcomes of UGIC patients treated consecutively at the Drug Development Unit, Royal Marsden Hospital, between 2005 and 2009, were recorded. RESULTS Ninety-six patients who previously received a median of 2 (range 1-4) lines of chemotherapies were treated in 30 Phase I trials. Of 81 evaluable patients, 9 achieved RECIST-objective response (11 %) with a 6-month clinical benefit rate of 14 %. Median progression free and overall survival were 7.7 weeks [95 %CI 7.7 (6.4-9.0)] and 19.1 weeks (95 %CI 17.5-20.8), respectively. Grade 3 or 4 toxicities were observed in 37 patients (39 %) and led to trial discontinuation in 9 (9 %); no toxicity-related death was recorded. In the multivariate analysis, serum albumin (<35 g/dl, HR2.0, p = 0.002) and lactate dehydrogenase (>192 μmol/l, HR1.7, p = 0.016) were prognostic of overall survival. CONCLUSION Phase I clinical trials can be considered a reasonable option in selected patients with relapsed UGIC. The use of objective prognosticators may improve selection and risk/benefit profile of patients.

Optimal chemotherapy for advanced gastric cancer: is there a global consensus? Gastric Cancer 2014; 17:213-25. [PMID: 24048758 DOI: 10.1007/s10120-013-0297-z] [Citation(s) in RCA: 86] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2013] [Accepted: 08/17/2013] [Indexed: 02/07/2023]
Abstract
The optimal medical treatment for advanced gastric cancer is currently the source of debate. Cytotoxic treatment has been shown to prolong survival and provide improved symptom control compared with best supportive care alone, but a global standard has not yet been defined. A literature research was undertaken. Results were evaluated by an international author team. The conclusions of this are presented in this paper. Combination chemotherapy with cisplatin and 5-fluorouracil was the preferred first-line chemotherapy, but oxaliplatin has shown equivalent efficacy to cisplatin. Oral fluoropyrimidines, especially S-1 and capecitabine, can substitute for 5-fluorouracil. Modern doublet regimens are preferred in the majority of patients on the basis of a balanced benefit-to-risk ratio. In selected fit and compliant patients, especially those with a high tumor burden or potential secondary resectability, a third drug may be added because triplet chemotherapy led to higher responses rates and enhanced efficacy. However, docetaxel also adds a significant increase in side effects. Monotherapy and early dose modifications should be considered in elderly and infirm patients. Beyond that, our understanding of gastric cancer tumor biology is increasing. In HER2-positive gastric cancer, the addition of the monoclononal anti-HER2 antibody trastuzumab to cisplatin and fluoropyrimidines has prolonged survival duration. Second-line chemotherapy with single agents has now become a proven treatment option. Alternatively, anti-angiogenic treatment with ramucirumab is on the horizon. In conclusion, combination chemotherapy is regarded as the global standard of care for the first-line treatment of advanced gastric cancer. Molecularly targeted treatments are being explored, preferably in combination with a backbone of chemotherapy doublets.

Abstract
BACKGROUND Quinacrine (QC), an antimalarial drug, has been shown to possess anticancer effect both in vitro (cancer cell lines) and in vivo (mouse models). In the cancer cells, QC can simultaneously suppress nuclear factor-κB and activate p53 signaling, which results in the induction of the apoptosis in these cells. However, the experimental results come from a few limited cancer cell lines, and the detailed mechanisms remain unknown. OBJECTIVE This study investigated the tumor-killing effects of QC on gastric cancer cells as well as underlying molecular pathways. METHODS SGC-7901 cells were treated with or without QC at different concentrations for 24 hours. The effect of QC on the inhibition of SGC-7901 cell proliferation was assessed by Cell Counting Kit-8 assay. Apoptosis was detected by examining nuclear morphology and quantifying phosphatidylserine externalization. Alterations in cellular morphology were analyzed by laser scanning confocal microscopy for fluorescent analysis. Cell cycle analysis was performed by propidium iodide (PI) staining and flow cytometry. The enzyme activity changes of caspase-3 were detected by colorimetry expression method. Western blot analysis was used to detect the changes in the protein level of Bax, Bc1-2, p53, and cytochrome c in cytosol of SGC-7901 cells. RESULTS Our results showed that QC could significantly inhibit the growth of SGC-7901 cells in a dose-dependent manner, with the IC50 mean (SD) value of 16.18 (0.64) μM, compared with nontreated controls. QC treatment (15 μM) could also induce apoptosis in SGC-7901 cells (26.30% [5.31%], compared with control group of 3.37% [0.81%]; P < 0.01), and the increasing phosphatidylserine level and the accumulation of chromatin nucleation in QC-treated cells provided further evidence. In addition, cell cycle analysis with PI staining showed that a significant S enriches, increasing from 12.00% (1.24%) (control) to 20.94% (2.40%) (QC treatment) (P < 0.01). Furthermore, increased activities of caspase-3 (increasing from 0.108 [0.019] to 0.628 [0.068]; P < 0.01) were observed in SGC-7901 cells treated with 15 μM QC. Western blot analysis showed that QC treatment significantly increased the levels of proapoptotic proteins, including cytochrome c, Bax, and p53, and decreased the levels of antiapoptotic protein Bcl-2, thus shifting the ratio of Bax/Bcl-2 in favor of apoptosis. CONCLUSIONS Our findings suggest that QC can significantly inhibit cell growth and induce apoptosis in SGC-7901 cells, which involves p53 upregulation and caspase-3 activation pathway.

Abstract
BACKGROUND Gastric cancer represents one of the most common causes of cancer deaths worldwide. Overexpression of ErbB2, a tyrosine kinase receptor involved in the pathogenesis of several human cancer types, has been reported also in gastric cancer. Thus, the inhibition of ErbB2 signal transduction pathways by the use of human antibodies could be a valuable strategy for the therapy of this type of cancer. METHODS We tested for the first time the antitumor effects on gastric cancer cells of Erb-hcAb, a novel fully human compact antibody, prepared in our laboratory, which targets a different epitope of ErbB2 with respect to trastuzumab, the only anti-ErbB2 antibody currently in clinical use for both breast and gastric cancer therapy. RESULTS Herein we demonstrate that the in vitro and in vivo growth of gastric cancer cells is efficiently inhibited by Erb-hcAb, which shows antitumor effects on the NCI-N87 cell line more potent than those observed for trastuzumab. CONCLUSIONS Erb-hcAb could be a promising candidate in the immunotherapy of gastric cancer as it combines the antiproliferative effect associated with the inhibition of ErbB2 signaling on tumor target cells with the ability to induce antibody-dependent cellular cytotoxicity.

Abstract
Gastric cancer is a highly aggressive disease. In metastatic setting, median overall survival, even with modern chemotherapy regimens, generally does not exceed 1 year and toxicity is a major concern. Angiogenesis plays a crucial role in cancer development and progression, and VEGF is one of the most important mediators of this process. Ramucirumab, an anti-VEGFR-2 antibody, has been recently evaluated in the large Phase III REGARD trial, demonstrating a significant survival benefit in second-line treatment of patients with advanced gastric or gastro-eosophageal junction adenocarcinoma. Unlike traditional chemotherapy, treatment with ramucirumab was associated with very few toxic effects. This article will review the main findings of the REGARD trial and discuss their potential impact on future treatment of metastatic gastric cancer.

Abstract
Background: This randomised phase II trial compared dose-escalated weekly paclitaxel (wPTX) vs standard-dose wPTX for patients with previously treated advanced gastric cancer (AGC). Methods: Ninety patients were randomised to a standard dose of wPTX (80 mg m−2) or an escalated dose of wPTX (80–120 mg m−2) to assess the superiority of overall survival (OS) with a one-sided alpha error of 0.3 and a power of 0.8. Results: The median OS showed a trend towards longer survival in the dose-escalated arm (11.8 vs 9.6 months; hazard ratio (HR), 0.75; one-sided P=0.12), although it was statistically not significant. The median progression-free survival (PFS) was significantly longer in the dose-escalated arm (4.3 vs 2.5 months, HR, 0.55; P=0.017). Objective response rate was 30.3% with dose escalation and 17.1% with standard dose (P=0.2). The frequency of all grades of neutropenia was significantly higher with dose escalation (88.7% vs 60.0%, P=0.002); however, no significant difference was observed in the proportion of patients experiencing grade 3 or more (40.9% vs 31.1%, P=0.34). Conclusion: Dose-escalated wPTX in patients with pretreated AGC met our predefined threshold of primary end point, OS (P<0.3); however, it did not show a significantly longer OS. Progression-free survival was significantly better with dose escalation.

Abstract
OBJECTIVE Biomarkers capable of discriminating the patients who are likely to respond to certain chemotherapeutic agents could improve the clinical efficiency. The sulfatases(SULFs) play a critical role in the pathogenesis of a variety of human cancers. Here, we focused our investigation on the prognostic and predictive impact of SULF2 methylation in gastric cancer. METHODS Promoter CpG island methylation of SULF2 was analyzed in 100 gastric cancer samples. The in vitro sensitivity to cisplatin, docetaxel, gemcitabine, irinotecan and pemetrexed were determined by histoculture drug response assay(HDRA). Additionally, 56 gastric cancer patients treated with a modified FOLFOX regimen(biweekly oxaliplatin plus 5-FU and folinic acid) were retrospectively analyzed to further evaluate the prognostic and predictive impact of SULF2 methylation in gastric cancer. RESULTS Methylated SULF2(SULF2M) was detected in 28 patients, while the remaining 72 patients showed unmethylated SULF2(SULF2U, methylation rate: 28%). Samples with SULF2U were more sensitive to cisplatin than those with SULF2M(inhibition rate: 48.80% vs. 38.15%, P = 0.02), while samples with SULF2M were more sensitive to irinotecan than SULF2U(inhibition rate: 53.61% vs. 40.92%, P = 0.01). There were no association between SULF2 methylation and in vitro sensitivity to docetaxel, gemcitabine and pemetrexed. SULF2 methylation was found to have a significant association with cisplatin efficacy(SULF2M: 57.14%, SULF2U: 80.56%, P = 0.02) and irinotecan efficacy(SULF2M: 89.29%, SULF2U: 62.50%, P = 0.01). Among the 56 patients receiving the modified FOLFOX regimen, a significant association was observed between survival and SULF2 methylation status(SULF2M: 309 days, 95% CI = 236 to 382 days; SULF2U: 481 days, 95% CI = 418 to 490 days; P = 0.02). Multivariate analysis revealed that SULF2 methylation was an independent prognostic factor of overall survival in gastric cancer patients treated with platinum-based chemotherapy. CONCLUSION SULF2 methylation is negatively associated with cisplatin sensitivity in vitro. SULF2 methylation may be a novel prognostic biomarker for gastric cancer patients treated with platinum-based chemotherapy.

Irinotecan combined with 5-fluorouracil and leucovorin third-line chemotherapy after failure of fluoropyrimidine, platinum, and taxane in gastric cancer: treatment outcomes and a prognostic model to predict survival. Gastric Cancer 2013; 16:581-9. [PMID: 23266882 DOI: 10.1007/s10120-012-0227-5] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2012] [Accepted: 11/27/2012] [Indexed: 02/07/2023]
Abstract
BACKGROUND The aim of this study was to evaluate the activity and safety of the combination chemotherapy of 5-fluorouracil (5-FU), leucovorin, and irinotecan (FOLFIRI regimen) after failure of fluoropyrimidine, platinum, and taxane in gastric cancer (GC) and to evaluate the prognostic factors for survival. METHODS Patients received biweekly FOLFIRI chemotherapy as third-line treatment. The FOLFIRI-1 consisted of irinotecan (180 mg/m(2) in a 2-h infusion) on day 1, and then leucovorin (200 mg/m(2) in a 2-h infusion) and 5-FU (a 400 mg/m(2) bolus, followed by 600 mg/m(2) in a 22-h continuous infusion) on days 1 and 2. FOLFIRI-2 consisted of irinotecan (180 mg/m(2) in a 2-h infusion) on day 1, and then leucovorin (400 mg/m(2) in a 2-h infusion) and 5-FU (a 400 mg/m(2) bolus, followed by 2400 mg/m(2) in a 46-h continuous infusion) on day 1. RESULTS A total of 158 patients were included. The overall response rate was 9.6 % in patients with measurable lesions. The median progression-free survival (PFS) and overall survival (OS) were 2.1 months [95 % confidence interval (CI), 1.7-2.5] and 5.6 months (95 % CI, 4.7-6.5), respectively. The major grade 3/4 toxicity was myelosuppression (36.7 %). Good performance status (PS), fewer metastatic sites, and longer duration from the first-line to third-line chemotherapy were independent prognostic factors affecting both PFS and OS. CONCLUSIONS The FOLFIRI regimen showed antitumor activity and tolerable toxicity profiles against advanced GC in the third-line setting. Patients with good PS, fewer metastatic sites and longer previous treatment duration might have the maximal benefit from third-line chemotherapy.
