Objective Molecular targeted drugs have anti-angiogenesis and anti-tumor effects.The study was to investigate the role of sunitinib on treating metastatic renal cell carcinoma ( mRCC) and its long-term efficacy and adverse reactions. Methods From November 2007 to March 2013, 281 mRCC patients were divided into two groups according to their own willingness.102 patients in the experimental group received sunitinib 50 mg per day.Pain score, metastatic focuses before and after targeted therapies were compared.179 patients in control group was treated by immunotherapy.Kaplan-Meier survival analysis was used to draw the survival curves and Cox regression model was applied in multivariate analysis. Results There was no difference between the two groups on baseline (P>0.05).In the experimental group, 78 cases were clear cell carcinoma, with remission rate 29.4%, stablity rate 53.8%and total effective rate 83.2%after treatment;15 cases were papillary renal cell carcinoma, with remission rate 33.3%, stablity ratio 46.7%and total effective rate 80.0% after treatment;9 cases were collecting duct carcinoma, with the remission rate 22.2%, the stablity ratio 55.6% and the total effective rate 77.8% after treatment.The bone scan after 1 cycle of treatment showed 2 cases progressed(10.5%), 5 cases relieved(26.3%) and 12 cases sta-blized(63.2%), the total effective rate of bone metastasis amounting to 89.5%, the effective rate of lung metastasis 81.7%, the effective rate of liver metastasis 60.0%and the effective rate of lymph node metastasis 72.8%.The median overall survival in the experimental group was 28.9 months, 20.7 months in control group(P<0.05).Cox regression analysis showed age, tumor classification, liver, lung, bone and lymph node metastasis were prognostic factors influencing mRCC.The common averse events were white blood cells, thrombocytopenia, neutropenia and hypoalbuminemia. Conclusion Sunitinib for the treatment of mRCC can diminish the metastatic focuses , ease the pain , improve the quality of life, delay the progression of the disease, and prolong the overall survival.

BACKGROUND:Recent investigations show that there are a small part of self-renewing and multi-potent cells named as tumor stem cells.Those cells share many characteristics with somatic and embryonic stem cells and are thought to be responsible for driving tumor progression in growing list of neoplastic diseases.Vascular endothelial growth factor(VEGF)is an important angiogenesis factor,which can regulate endothelial proliferation,angiogenesis,permeability of blood vessel,and thrombogenesis.OBJECTIVE:To summarize the progress of cancer stem cells and tumor angiogenesis.METHODS:A computer-based online search was conducted in PUMMED,CNKI,and Wanfang databases with the key words of "cancer stem cells,vascular endothelial growth factor,new vascularize" in both Chinese and English from January 2000 to October 2009.RESULTS AND CONCLUSION:Among 153 articles,there were 13 in Chinese and 140 in English.Titles and abstracts were preliminarily screened,and articles which were non-relative(n=35),duplicated(n=30),and Meta analysis(n=57),were excluded.A total of 31 articles were included in the final analysis.Angiogenesis regulated by multiple factors was a necessary link for tumor growth and transferring.Stem cells promoted angiogenesis,thereby promoted tumor growth and transferring.However,the modified stem cells caused the opposite effects.On the other hand,the stem cells were considered as a substance vector to localize tumor focus,in particular,it will be potential for looking for subclinical focus and distal focus.

Objective To compare elasticity imaging and conventional ultrasound when applied to the diagnosis of benign and malignant breast tumors.Methods Totally 124 breast tumor patients (140 lesions) from some hospital were analyzed retrospectively,who were divided into a control group and an observation group according to ultrasound examination ways.The control group involved in 60 patients with 66 lesions undergoing conventional ultrasound examination,and the observation group had 64 patients with 74 lesions undergoing elasticity imaging.Pathological findings were considered as gold standard,and the two groups were compared on accuracy,specificity and sensitivity.Results Pathological detection found the accuracy,specificity and sensitivity of the malignant tumor in the control group were 85.00％,84.78％ and 84.85％ respectively,and the ones of the malignant tumor in the observation group were 95.83％,96.00％ and 95.95％ respectively.The two groups had significant differences between the accuracies,specificities and sensitivities (P＜0.05).Conclusion Elasticity imaging describes the size,shape,number,margin and etc of the breast tumor,and thus can enhance the accuracy,specificity and sensitivity for diagnosing breast tumors.
