05)。治疗后,实验组KPS评分提高率明显高于对照组(P<0.05)。整个维持治疗过程中无治疗相关性死亡。结论:晚期NSCLC患者在化疗后采用参一胶囊维持治疗,可显著提高患者免疫功能、改善生活质量,且安全性良好,疗效显著,值得在临床上推广应用。
目的探讨血管生成抑制蛋白1(vashohibin-1,VASH1)、微血管密度(microvessel density,MVD)在非小细胞肺癌(non-small-cell

lung cancer,NSCLC)组织中的表达及VASH1与临床病理特征及MVD的关系。方法采用免疫组织化学方法检测72例NSCLC组织、30例癌旁组织、21例肺良性病变组织蜡块中VASH1表达与MVD水平,同时分析VASH1与NSCLC患者临床病理特征的关系,并探讨其与MVD二者之间的相关性。结果 NSCLC、癌旁组织和肺良性病变组织中VASH1蛋白阳性表达率分别为73.6%(53/72)、26.7%(8/30)、14.3%(3/21),三者间比较差异有统计学意义(χ~2=33.15,P<0.01)。VASH1的表达在NSCLC的淋巴结转移、TNM分期和分化程度方面差异有统计学意义(均P
Preclinical KRX-0401制造商 modelling studies are beginning to aid development of therapies targeted against key regulators of pancreatic cancer progression. Pancreatic cancer is an aggressive, stromally-rich tumor, from which few people survive.

Within the tumor microenvironment cellular and extracellular components exist, shielding tumor cells from 很少 immune cell clearance, and chemotherapy, enhancing progression of the disease. The cellular component of this microenvironment consists mainly of stellate cells and inflammatory cells. New findings suggest that manipulation of the cellular component of the tumor microenvironment is possible to promote immune cell killing of tumor cells. Here we explore possible immunogenic therapeutic strategies. Additionally extracellular stromal elements play a key role in protecting tumor cells from chemotherapies targeted at the pancreas. We describe the experimental findings and the pitfalls associated with translation of stromally targeted therapies to clinical trial. Finally,

we discuss the key inflammatory signal transducers activated subsequent to driver mutations in oncogenic Kras in pancreatic cancer. We present the preclinical findings that have led to successful early trials of STAT3 inhibitors in pancreatic adenocarcinoma.
Since the discovery that non-small cell lung cancer(NSCLC) is driven by epidermal growth factor receptor(EGFR) mutations, the EGFR tyrosine kinase inhibitors(EGFR-TKIs, e.g., ge fi tinib and elrotinib) have been effectively used for clinical treatment. However, patients eventually develop drug resistance. Resistance to EGFR-TKIs is inevitable due to various mechanisms, 此网站 such as the secondary mutation(T790M), activation of alternative pathways(c-Met, HGF, AXL), aberrance of the downstream pathways(K-RAS mutations, loss of PTEN), impairment of the EGFR-TKIs-mediated apoptosis pathway(BCL2-like 11/BIM deletion polymorphism), histologic transformation, ATP binding cassette(ABC) transporter effusion, etc. Here we review and summarize the known resistant mechanisms to EGFR-TKIs and provide potential targets for development of new therapeutic strategies.
