RESUMO

The aim of this study was to explore potential novel plasma protein biomarkers for lung adenocarcinoma (LUAD). A plasma proteomics analysis was carried out and candidate protein biomarkers were validated in 102 LUAD cases and 102 matched healthy controls. The same LUAD tumor tissues were detected to explore the correlation between the expression of candidate proteins in tissues and plasma and vascular normalization. A LUAD active metastasis mice model was constructed to explore the role of candidate proteins for lung metastasis. GPI and PGD were verified to be upregulated in plasma from LUAD patients, and the expression of GPI in tumor tissue was positively correlated with the expression of GPI in plasma and negatively correlated with the normalization of tumor blood vessels. Meanwhile, a negative correlation between the expression of GPI and PGD in plasma and tumor vascular normalization was discovered. In the LUAD active metastasis model, the lowest levels of vascular normalization and the highest expression of GPI and PGD were found in mice with lung metastases. This study found that GPI and PGD may be potential plasma biomarkers for LUAD, and monitoring those may infer the risk of metastasis and malignancy of the tumor. SIGNIFICANT: We identified GPI and PGD as potential novel diagnostic and prognostic biomarkers for LUAD. PGD and GPI can be used as diagnostic biomarkers in combination with other available strategies to assist in the screening and diagnosis of LUAD, and as prognostic biomarkers aid in predict the risk of tumor metastasis and malignancy in patients with LUAD.

RESUMO

BACKGROUND: Xihuang Pills/Capsules have a longstanding history of utilization in traditional Chinese medicine (TCM) for treating cancer. Nevertheless, a comprehensive investigation is required regarding the specific impacts and safety of Xihuang Pills/Capsules in individuals with uterine cervical neoplasms. Thus, conducting a meta-analysis is essential to evaluate the clinical effectiveness of combining Xihuang Pills/Capsules with Western medicine in patients with cervical neoplasms. METHODS: The research involved searching 5 English and 4 Chinese databases for randomized controlled trials (RCTs) investigating the use of Xihuang Pills/Capsules in conjunction with Western medicine for treating uterine cervical neoplasms. Subsequently, statistical analysis was carried out using Review Manager software (version 5.3). RESULTS: This research encompassed 10 RCTs involving 937 patients. The findings revealed that the combination of Xihuang Pills/Capsules with Western medicine treatment led to improvements in various aspects of the patients' condition. Specifically, there was an enhancement in the short-term efficacy rate (risk ratio [RR] = 1.14, 95% confidence interval [CI]: 1.06-1.22, P = .0003), Karnofsky performance score (KPS) (mean difference [MD] = 5.90, 95% CI: 0.54-11.26, P = .03), survival rates, CD3+, CD3 + CD4+, CD3 + CD8+, CD3-CD56 + cells, and immunoglobulin M in patients with uterine cervical neoplasms. Moreover, the combination treatment resulted in a reduction of adverse reactions, including gastrointestinal reactions (RR = 0.52, 95% CI: 0.42-0.64, P < .00001), radiation proctitis (RR = 0.47, 95% CI: 0.33-0.68, P < .0001), myelosuppression (RR = 0.41, 95% CI: 0.26-0.64, P < .0001), as well as carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC-Ag) levels. Additionally, the treatment exhibited an inhibitory effect on white blood cells (WBCs) and platelets (PLTs). CONCLUSION: The amalgamation of Xihuang Pills/Capsules with conventional anti-tumor therapy proves to be both effective and safe in the treatment of cervical neoplasms. However, further validation through high-quality RCTs is necessary to substantiate these findings.

RESUMO

Background: Apatinib has shown outstanding value in the treatment of advanced gastric cancer (AGC). However, no biomarkers are available to select AGC patients who will benefit from apatinib. The aim of the present study was to investigate the association between p53 and Ki67 expression of and the outcome in AGC patients treated with apatinib. Methods: From December 2015 to December 2020, 92 AGC patients were enrolled and was retrospectively evaluated. They were given apatinib at a daily dose of 500 or 250 mg every 4 weeks to monitor clinical efficacy and adverse events (AEs). Kaplan-Meier method was used for survival analysis. Expression of p53 and Ki67 was detected by immunohistochemistry (IHC) and correlated with survival. Results: Among 92 evaluable patients, the objective response rate (ORR) and disease control rate (DCR) were 17.4% and 79.3%, respectively, and none of them achieved a CR, 16 achieved a PR (17.4%) (95% CI 9.8%-26.1%). Stable disease (SD) was observed in 57.6% of patients (95% CI 49.2%-69.9%) and PD in 21.7% of patients (95% CI 13.6%-31.3%). The median progression free survival (mPFS) was 122.7 ± 8.2 days, and the median overall survival (mOS) was 203.4 ± 11.9 days. P53 expression was observed in 35 patients (38.0%) and high expression of Ki67 was detected in 34 patients (37.0%). There was a statistically significant inverse relationship between p53 and Ki67 expression (P=0.014). Moreover, p53 was significantly correlated with the OS (P=0.018), but Ki67 had no significant influence on OS. Conclusions: Apatinib showed promising efficiency and was well tolerated as a second-line treatment for AGC patients. AGC patients with p53-negative were likely to benefit from apatinib treatment; however, the expression of Ki67 proteins has no significant impact on the outcome of AGC patients.

RESUMO

Colorectal cancer (CRC) is a major global health problem and one of the major causes of cancer-related death worldwide. It is very important to understand the pathogenesis of CRC for early diagnosis, prevention strategies and identification of new therapeutic targets. Intercellular adhesion molecule-1 (ICAM-1, CD54) displays an important role in the the pathogenesis of CRC. It is a cell surface glycoprotein of the immunoglobulin (Ig) superfamily and plays an essential role in cell-cell, cell-extracellular matrix interaction, cell signaling and immune process. It is also expressed by tumor cells and modulates their functions, including apoptosis, cell motility, invasion and angiogenesis. The interaction between ICAM-1 and its ligand may facilitate adhesion of tumor cells to the vascular endothelium and subsequently in the promotion of metastasis. ICAM-1 expression determines malignant potential of cancer. In this review, we will discuss the expression, function, prognosis, tumorigenesis, polymorphisms and therapeutic implications of ICAM-1 in CRC.

RESUMO

Background: Alternative polyadenylation (APA) events may be modulated by single nucleotide polymorphisms (SNPs). Therefore, this study aims to evaluate the association between APA quantitative trait loci (apaQTLs)-related SNPs (apaQTL-SNPs) and non-small-cell lung cancer (NSCLC) risk. Methods: APA-related genes associated with NSCLC (LUAD and LUSC) were first identified, and the respective apaQTL-SNPs of those genes were selected. Then, a two-phase case-control study was performed to evaluate the association between candidate apaQTL-SNPs and NSCLC risk. Results: A total of 7 LUAD- and 21 LUSC-associated apaQTL-SNPs were selected. In the first phase, the apaQTL-SNP rs10138506 was significantly associated with LUAD risk (p < 0.05), whereas the other two apaQTL-SNPs (rs1130698 and rs1130719) were significantly associated with LUSC risk (p < 0.05). In the second phase, the variant G allele of rs10138506 was still significantly associated with an increased risk of LUAD (OR = 1.42, 95%CI = 1.02−1.98, p = 0.038). Functional annotation indicated that the variant G allele of rs10138506 was significantly associated with a higher PDUI value of CHURC1. Meanwhile, 3'RACE experiments verified the presence of two poly(A) sites (proximal and distal) in CHURC1, while qRT-PCR results indicated that different genotypes of rs1127968 which, in perfect LD with rs10138506, can mediate changes in the lengths of the 3'UTR of CHURC1 isoforms. Conclusion: The variant G allele of rs10138506 in CHURC1 was correlated with a longer 3'UTR of CHURC1 mRNA and an increased LUAD risk. Further studies should evaluate the interaction between rs10138506 and different 3'UTR lengths of CHURC1 that regulate LUAD development.

RESUMO

Cholesterol metabolism is highly correlated with risks of pancreatic ductal adenocarcinoma (PDAC). Nevertheless, the underlying mechanisms of activation of cholesterol biogenesis remain inconclusive. KIF11 is a key component of the bipolar spindle and expresses highly in various malignancies. However, its functional role in PDAC tumorigenesis is still unclear. This study aims to elucidate the oncogenic functions of KIF11 in stimulating cholesterol metabolism, thereby driving PDAC progression. We utilized bioinformatics analysis to identify that KIF11 expressed highly in tumor samples versus paired normal tissues and high KIF11 correlated with high clinical stages of patients. Patients with high KIF11 had worse survival outcomes relative to those with low KIF11. Gene set enrichment analysis (GSEA) revealed that KIF11 correlated intensively with the mevalonate (MVA) metabolic pathway. Positive associations were observed between KIF11 and MVA-signature (HMGCR, FDFT1, SQLE, and MSMO1). KIF11 could elevate the free cholesterol content of PDAC cells and targeting MVA inhibited the in vitro growth of KIF11-overexpressing cells. Mechanistically, we found KIF11 could interact with SREBP2, the master regulator of MVA. High KIF11 could increase SREBP2 proteins, but not alter their mRNA levels. KIF11 could attenuate the ubiquitination-mediated degradation of SREBP2, thereby enhancing its stability and accumulation. Accordingly, KIF11 stimulated the expressions of MVA-signature and free cholesterol contents depending on SREBP2. In addition, KIF11 depended on SREBP2 to promote cell growth, migration, stemness, and colony formation abilities. The subcutaneous xenograft models indicated that targeting MVA biogenesis (atorvastatin) is effective to restrict the in vivo growth of KIF11high PDAC. Taken together, our study identified that KIF11 could activate the MVA cross talk to drive PDAC progression and inhibiting the KIF11/MVA axis provided a therapeutic vulnerability in the treatment of PDAC.

RESUMO

Pulmonary nodules are the early manifestation of lung cancer, which appear as circular shadow of no more than 3 cm on the computed tomography (CT) image. Accurate segmentation of the contours of pulmonary nodules can help doctors improve the efficiency of diagnosis. Deep learning has achieved great success in computer vision. In this study, we propose a novel network for pulmonary nodule segmentation from CT images based on U-NET. The proposed network has two merits: one is that it introduces dense connection to transfer and utilize features. Additionally, the problem of gradient disappearance can be avoided. The second is that it introduces a new loss function which is tolerance on the pixels near the borders of the nodule. Experimental results show that the proposed network at least achieves 1% improvement compared with other state-of-art networks in terms of different criteria.

RESUMO

Long non-coding RNAs (LncRNAs) play vital roles in the tumorigenesis of many cancers. Single nucleotide polymorphisms (SNPs) of the lncRNA also play vital roles in tumorigenesis. We explored lncRNA rs944289 and rs7990916 polymorphisms and analyzed the relationship between these lncRNA polymorphisms with the colorectal cancer (CRC) risk in a Chinese population. We recruited 1003 CRC patients from the Affiliated People's Hospital of Jiangsu University and the Fujian Medical University Union Hospital from October 2014 to August 2017. Genomic DNA was extracted using a DNA Kit from lymphocytes of peripheral blood and the genotyping was performed with a SNPscan method. We found that the rs944289 TT homozygote was associated with the decreased CRC risk in the overall population. LncRNA rs944289 TT decreased the CRC risk in the subgroup of female, male, age ≥ 61, without alcohol intake, smoking and BMI ≥ 24 by logistic regression. The subgroup analysis revealed that lncRNA rs7990916 was not associated with CRC risk except for age < 61. Logistic regression analysis revealed that lncRNA rs944289 TT homozygote was associated with the increased risk of rectum cancer (TT vs. CC + CT: adjusted OR = 1.29, 95% CI 1.10-1.66, P = 0.041) or colon cancer. In summary, we proved that lncRNA rs944289 might be significantly related to the decreased CRC risk in the Chinese Han populations and lncRNA rs7990916 was not associated with the CRC risk except for patients of age < 61. In the future, studies with larger samples should be conducted to validate our results.

RESUMO

Aims: This study aimed to retrospectively determine the influence factors and survival effects of chemotherapy in pathological T3N0M0 esophageal cancer (EC) patients based on histological type. Methods: A total of 1136 pathological T3N0M0 EC patients who had surgery were chosen from the Surveillance, Epidemiology and End Results database. The patients were divided into subgroups based on histological type and chemotherapy status. Multivariate logistic regression, log-rank test and Cox regression were used to identify prognostic risk factors and survival differences. A propensity score matching analysis was applied to adjust the covariates. The impact of additional chemotherapy was also assessed in patients who had postoperative radiotherapy. Results: The 5-year overall survival was 36.4% for all patients. Chemotherapy was an independent protective factor of survival in both adenocarcinoma and squamous cell carcinoma patients. In the survival analysis, chemotherapy significantly improved the prognosis of EC patients, both for adenocarcinoma and squamous cell carcinoma. Propensity score matching analysis validated these results. Conclusion: Chemotherapy is recommended for pathological T3N0M0 EC patients regardless of histological type.


Lay abstract The prognosis of patients with different histological types of esophageal cancer varies. Chemotherapy is important treatment for these patients. However, the survival benefits of chemotherapy with regard to histological type and clinical stage are unclear. Here the authors used a public database to explore the prognostic value of chemotherapy and survival influence factors in these patients.

RESUMO

ABSTRACT: Advanced gastric cancer (AGC) patients are not tolerant to the toxicities of traditional chemotherapy and its second-line therapeutic regimens are limited. The aim of the present study is to evaluate the efficacy and safety of apatinib combined with S-1 as the second-line therapy for AGC patients.Patients with AGC were enrolled in this study. Patients received oral apatinib (250 mg to 500 mg once daily) and S-1(40 mg/m2 twice daily) on days 1-14. Each cycle was 28 days and one course of treatment consisted of 2 cycles. Clinical efficacy and adverse events (AEs) were observed. Kaplan-Meier method was used for survival analysis.From November 2015 to December 2017, 58 AGC patients who failed first-line chemotherapy were enrolled and assessed retrospectively. According to the Response Evaluation Criteria in Solid Tumors (RECIST) standard, all patients were evaluable for response. None achieved CR, and 10 (17.2%) achieved PR (95% CI 7.2%-27.3%). SD was observed in 58.6% (34/58) of patients (95% CI 45.6%-71.7%) and NR in 24.1% (14/58) of patients (95% CI 12.8%-35.5%). The objective response rate (ORR) and the disease control rate (DCR) were 17.2% and 75.8% respectively. The median progression-free survival (PFS) and median overall survival (OS) were 143.1 days (95% CI 121.7-164.5) and 211.6 days (95% CI 162.9-219.7) respectively. The multivariate analysis showed that the ECOG PS was the independent factor of PFS and OS for AGC patients (PFS: HR = 3.565, 95% CI: 2.25-5.65, P < .001; OS: HR = 3.676, 95% CI: 2.29-5.89, P < .001). The main AEs were fatigue (72.4%), hypertension (46.6%), and leukopenia (48.3%).Apatinib combined with S-1 showed promising efficiency and was well tolerated as the second-line therapy for AGC patients. ECOG PS was the independent factor of PFS and OS for AGC patients. AEs were moderate and controllable, and leukopenia or hypertension was predictable factors for the PFS and OS of AGC patients.

RESUMO

BACKGROUND: Gastric cancer (GC) is a malignant tumor with a significantly high mortality rate, yet, its pathogenesis is not fully understood. Bioinformatics predicted that LINC01224 is highly expressed in stomach adenocarcinoma (STAD), and showed that LINC01224 adsorbed miR-193a-5p to target CDK8. Therefore, this study intended to verify the effect of the LINC01224/miR-193a-5p/CDK8 axis on the biological behavior of gastric cancer. METHODS: Expressions of LINC01224, miR-193a-5p, CDK8, apoptosis-, and EMT-related genes were analyzed using the GEPIA website, RT-qPCR, in situ hybridization, and Western blot as needed. Bioinformatics and dual luciferase assay were used to evaluate the relationship between LINC01224, miR-193a-5p, and CDK8. Functional experiments and rescue experiments (MTT assay, flow cytometry, wound healing assay, and Transwell) were conducted to detect the effects of the above genes on the biological characteristics of GC cells. Tumorigenesis assay was used to verify the results of in vitro experiments. RESULTS: LINC01224 adsorbed miR-193a-5p to target and upregulate CDK8. The expressions of LINC01224 and CDK8 were increased, while the expression of miR-193a-5p was decreased in GC. Overexpressed LINC01224 promoted cell viability, migration and invasion, accelerated tumor formation, attenuated apoptosis, inhibited the expressions of apoptosis-related proteins, and promoted the expressions of EMT-related proteins, whereas silenced LINC01224 led to the opposite effect. MiR-193a-5p inhibitor partially offset the effect of silenced LINC01224; interestingly, siCDK8 significantly reversed the effect of miR-193a-5p inhibitor on GC cells. CONCLUSION: LINC01224 affects the biological behavior of gastric cancer by mediating miR-193a-5p to regulate CDK8.

RESUMO

MicroRNAs (miRNAs) delivered by gastric cancer (GC)-secreted extracellular vesicles (GC-EVs) are associated with the immune escape in GC. Microarray analysis based on the GEO: GSE112369 dataset identified the presence of poorly expressed CXXC finger protein 4 (CXXC4) in GC, which was validated in clinical samples of GC patients. Moreover, prediction based on TargetScan analysis demonstrated the putative miR-675-3p binding site in the 3' UTR region of CXXC4. Thereby, our study aims to determine the role of GC-EV-encapsulated miR-675-3p in GC. First, CXXC4 was found to be negatively correlated with programmed cell death 1 ligand 1 (PD-L1). The effects of mitogen-activated protein kinase (MAPK) signaling on GC were evaluated using activator of the MAPK pathway. The overexpression of CXXC4 led to a downregulated MAPK signaling pathway, thus decreasing PD-L1 expression to augment the proliferation and activation of T cells co-cultured with GC HGC-27 cells. GC-EV-encapsulated miR-675-3p negatively regulated the expression of its target gene CXXC4. GC-EV-encapsulated miR-675-3p increased PD-L1 expression to stimulate the immune escape in vitro and EV-encapsulated miR-675-3p accelerated cisplatin resistance in vivo. Collectively, the aforementioned findings present a mechanism in which EV-mediated miR-675-3p upregulates PD-L1 expression, promoting immune escape in GC.

RESUMO

PURPOSE: To explore the expression of WD-40 repeat and SOCS box containing 1 (WSB1) and its clinical significance in hepatocellular carcinoma (HCC). METHODS: Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of WSB1 in clinical tissues. Survival curves were platted using the Kaplan-Meier method and log rank test was used to compare survival between groups. The influencing factors for the long-term survival were analysed using Cox univariate and multivariate analysis. In in vitro study, Western blot was used to evaluate the effects of WSB1 on epithelial-mesenchymal transition (EMT) of tumor cells. RESULTS: The expression of WSB1 was much higher in cancer tissues than that in para-normal tissues, and the WSB1 expression was correlated with tumor differentiation, lymph node metastasis and clinical stage. In addition, HCC patients with higher WSB1 expression had significantly poorer progression-free survival (PFS) and overall survival (OS). Both univariate analysis and multivariate analyses indicated that high expression of WSB1 was an independent predictor of poor prognosis in HCC. Further in in vitro study, downregulation of WSB1 in HCC cell line could reduce the expression of epithelial phenotype protein (E-cadherin) while increase the expression of mesenchymal phenotype protein (N-cadherin and Vimentin). CONCLUSIONS: WSB1 might contribute into the development of HCC and serve as a clinical biomarker and a therapeutic target for HCC patients.

RESUMO

Gastric cancer, is the fourth most common tumour type yet, ranks second in terms of the prevalence of cancer-related deaths worldwide. CXXC finger protein 4 (CXXC4) has been considered as a novel cancer suppressive factor, including gastric cancer. This study attempted to investigate the possible function of CXXC4 in gastric cancer and the underlying mechanism. The binding of the ETS domain-containing protein-1 (ELK1) to the long non-coding RNA MIR100HG promoter region was identified. Then, their expression patterns in gastric cancer tissues and cells (SGC7901) were detected. A CCK-8 assay was used to detect SGC7901 cell proliferation. Subsequently, SGC7901 cells were co-cultured with CD3+ T cells, followed by measurement of CD3+ T cell proliferation, magnitude of IFN-γ+ T cell population and IFN-γ secretion. A nude mouse model was subsequently developed for in vivo validation of the in vitro results. Low CXXC4 expression was found in SGC7901 cells. Nuclear entry of ELK1 can be inhibited by suppression of the extent of ELK1 phosphorylation. Furthermore, ELK1 is able to bind the MIR100HG promoter. Overexpression of CXXC4 resulted in weakened binding of ELK1 to the MIR100HG promoter, leading to a reduced proliferative potential of SGC7901 cells, and an increase in IFN-γ secretion from CD3+ T cells. Moreover, in vivo experiments revealed that CXXC4 inhibited immune escape of gastric cancer cells through the ERK1/2 axis. Inhibition of the CXXC4/ELK1/MIR100HG pathway suppressed the immune escape of gastric cancer cells, highlighting a possible therapeutic target for the treatment of gastric cancer.

RESUMO

Large granular lymphocytic leukemia (LGLL) is a chronic clonal lymphoproliferative disease of mature T or NK cells, and produces a variety of hematological abnormalities. Pure red cell aplasia (PRCA) is a rare haematological disease and is one of the most common complications of LGLL. LGLL-associated PRCA may represent a relatively indolent type and may be more common than reported, but its natural history and clinical course have not been well described. The ethnic origin of the patients is an important consideration in determining the relationship between PRCA and LGLL. Guidelines and progresses for management of LGLL-associated PRCA rely on accumulation of empirical experiences, integrative analyses of several cases and clinical trials.

RESUMO

Post-transplant lymphoproliferative disorders (PTLD) represent a heterogeneous group of diseases that occur following transplantation. Large granular lymphocytic (LGL) lymphocytosis is one type of PTLD, ranging from reactive polyclonal self-limited expansion to oligo/monoclonal lymphocytosis or even to overt leukaemia. LGL lymphocytosis in transplant recipients may present as a relatively indolent version of the condition and may be more common than reported, but its natural history and clinical course have not been well described, and the lack of a reliable classification system has limited studies on this disease. Patients with unexplained cytopenias, autoimmune manifestations, or unexpected remissions may be mislabelled. The purpose of this review was to evaluate the clinical features, immunophenotypes, etiopathogenesis, diagnosis, outcomes and treatment of post-transplantation LGL lymphocytosis. In conclusion, LGL lymphocytosis is a frequent occurrence after transplantation that correlates with certain procedural variables and post-transplant events. LGL lymphocytosis should be considered in patients with unexplained lymphocytosis or when pancytopenia develops after transplantation. The diagnosis of LGL lymphocytosis requires a demonstration of monoclonality, but clonality does not indicate malignancy. Additional studies are necessary to further delineate the potential effects of large granular lymphocytes in the long-term prognosis of post-transplant patients.

RESUMO

PURPOSE: This systematic analysis was conducted to evaluate the efficacy and safety of pemetrexed-based chemoradiotherapy in treating patients with locally advanced or metastatic esophageal cancer. METHODS: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for relevant patients were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. RESULTS: For pemetrexed-based regimens, 4 clinical studies including 47 patients with locally advanced or metastatic esophageal cancer were considered eligible for inclusion. Systematic analysis showed that, in all patients, the pooled RR was 51% (24/47) . Major adverse effects of grade III/IV were esophagitis, neutropenia, thrombocytopenia, anemia anorexia, fatigue, diarrhea, dysphagia and vomiting. No treatment related death occurred with pemetrexed-based treatment. CONCLUSION: This systematic analysis suggests that pemetrexed based radiotherapy is associated with reasonable activity and good tolerability in treating patients with locally advanced or metastatic esophageal cancer.

RESUMO

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.

RESUMO

OBJECTIVE: To investigate the efficacy and safety of Yadanzi® (Javanica oil emulsion injection) combined with chemotherapy for treatment of patients with advanced gastric cancer. METHODS: From January 2011 to December 2012, we recruited 75 patients with advanced gastric cancer, who received javanica oil emulsion injection together with chemotherapy. After two cycles of treatment, efficacy and safety of the combined therapies were evaluated. RESULTS: Overall response rate of 75 patients after treatment was 85.3% (CR+PR+SD). Treatment related side effects were recorded. No treatment related death occurred. CONCLUSIONS: Javanica oil emulsion injection combined with chemotherapy could be considered as a safe and effective regimen in treating patients with advanced gastric cancer. Further randomized clinical trials should be conducted to confirm whether the addition of Yadanzi® to chemotheraphy could be associated with reduced toxicity, enhanced tolerability and improved quality of life for patients with advanced gastric cancer.
