Objective： To review the anticancer effects of Radix astragali （RA）, one of the most commonly used herbs to manage cancer in East Asia, and its constituents and to provide evidence of clinical usage through previously performed clinical studies. Methods： Preclinical and clinical studies related to the anticancer effects of RA were searched from inception to November 2013 in electronic databases. Two reviewers independently investigated 92 eligible studies, extracted all the data of studies and appraised methodological quality of clinical trials. The studies were categorized into in vitro and in vivo experimental studies and clinical studies, and analyzed by saponins, polysaccharides, and flavonoids of RA constituents, RA fraction, and whole extract. Results： In preclinical studies, RA was reported to have tumor growth inhibitory effects, immunomodulatory effects, and attenuating adverse effects by cytotoxic agents as well as chemopreventive effects. Saponins seemed to be the main constituents, which directly contributed to suppression of tumor growth through the activation of both intrinsic and extrinsic apoptotic pathway, modulation of intracellular signaling pathway, and inhibition of invasion and angiogenesis. Flavonoids suppressed tumor growth through the similar mechanisms with saponins. Polysaccharides showed immunomodulatory effects, contributing tumor shrinkages in animal models, despite the low cytotoxicity to cancer cells. Most of the clinical studies were performed with low evidence level of study designs because of various limitations. RA whole extracts and polysacchaddes of RA were reported to improve the quality of life and ameliorate myelosuppression and other adverse events induced by cytotoxic therapies. Coaclusion： The polysaccharides, saponins, and flavonoids of RA, and the whole extract of RA have been widely reported with their anticancer effects in preclinical studies and showed a potential application as a adjunctive cancer therapeutics with t

AIM: To investigate the impact of systemic inflammationbased prognostic markers on overall survival in relapsed/refractory metastatic colorectal cancer(m CRC) patients. METHODS: To investigate prognostic markers in m CRC patients,this study was performed with patients who have experienced relapsed/refractory m CRC with standard chemotherapy or were inapplicable to conventional treatment modality because of poor performance status,age,or comorbidity. We reviewed the medical records of 177 m CRC patients managed with Korean Medicine(KM) treatment modality using an anticancer agent of Rhus verniciflua Stokes extract from June 2006 to April 2013. The clinicopathologic characteristics,laboratory test,the systemic inflammation markers including the modified Glasgow prognostic score(m GPS),neutrophil lymphocyte ratio(NLR),platelet lymphocyte ratio(PLR),lymphocyte monocyte ratio(LMR),and prognostic nutritional index(PNI) were analyzed. The overall survival of patients was calculated with the Kaplan-Meier method and the statistical significance was compared using with the log-rank test. To compare the impact of systemic inflammation based markers,the hazard ratio(HR) of m GPS,NLR,PLR,LMR,and PNI for overall survival were evaluated with the Cox proportional hazards ***: The majority of m CRC patients had relapsed/refractory to standard chemotherapy; 128 patients(72.3%) had undergone more than second line chemotherapy,and the median time from diagnosis of m CRC to initiation of KM was 9.4 mo. The median overall survival of enrolled patients was 8.3 mo. On univariate analyses,the inflammation markers of higher m GPS(P 300(P = 0.004),LMR ≤ 3.4(P < 0.001),and PNI ≤ 45.3(P = 0.001) were significantly associated with decreased survival time. On stepwise multivariate proportional hazards model,m GPS at 2 vs 0(HR = 3.212,95%CI: 1.437-7.716,P = 0.004),and LMR ≤ 3.4(HR = 1.658,95%CI: 1.092-2.518,P = 0.018) as independent predictors assoc
