| 1 | Cultured circulating tumor cells and their derived xenografts for personalized oncology显示文摘Recent cancer research has demonstrated the existence of circulating tumor cells(CTCs)in cancer patient’s blood.Once identified,CTC biomarkers will be invaluable tools for clinical diagnosis,prognosis and treatment.In this review,we propose ex vivo culture as a rational strategy for large scale amplification of the limited numbers of CTCs from a patient sample,to derive enough CTCs for accurate and reproducible characterization of the biophysical,biochemical,gene expressional and behavioral properties of the harvested cells.Because of tumor cell heterogeneity,it is important to amplify all the CTCs in a blood sample for a comprehensive understanding of their role in cancer metastasis.By analyzing critical steps and technical issues in ex vivo CTC culture,we developed a cost-effective and reproducible protocol directly culturing whole peripheral blood mononuclear cells,relying on an assumed survival advantage in CTCs and CTC-like cells over the normal cells to amplify this specified cluster of cancer cells. | Ruoxiang Wang Gina CYChu Stefan Mrdenovic Alagappan A.Annamalai Andrew E.Hendifar Nicholas N.Nissen James S.Tomlinson Michael Lewis Nallasivam Palanisamy Hsian-Rong Tseng Edwin M.Posadas Michael R.Freeman Stephen J.Pandol Haiyen E.Zhau Leland W.K.Chung | 2016 | Asian Journal of Urology2016，3，4： | 2 |
| 2 | Applications of circulating tumor cells for prostate cancer显示文摘One of the major challenges that clinicians face is in the difficulties of accurately monitoring disease progression.Prostate cancer is among these diseases and greatly affects the health of men globally.Circulating tumor cells(CTCs)are a rare population of cancer cells that have shed from the primary tumor and entered the peripheral circulation.Not until recently,clinical applications of CTCs have been limited to using enumeration as a prognostic tool in Oncology.However,advances in emerging CTC technologies point toward new applications that could revolutionize the field of prostate cancer.It is now possible to study CTCs as components of a liquid biopsy based on morphological phenotypes,biochemical analyses,and genomic profiling.These advances allow us to gain insight into the heterogeneity and dynamics of cancer biology and to further study the mechanisms behind the evolution of therapeutic resistance.These recent developments utilizing CTCs for clinical applications will greatly impact the future of prostate cancer research and pave the way towards personalized care for men. | Shirley Cheng Jie-Fu Chen Yi-Tsung Lu Leland W.K.Chung Hsian-Rong Tseng Edwin M.Posadas | 2016 | Asian Journal of Urology2016，3，4： | 1 |
| 3 | Biology and therapy of urological cancer metastasis显示文摘From the early roots of modern urology to today,genitourinary(GU)cancers have been an important part of the fields of urology and cancer biology.As medical science has advanced,newer clinical and basic viewpoints have impacted the thinking and practice in this important field.As such,GU oncology has been consistently seen as an area of rapid evolution both in biological understanding and clinical care.GU cancers continue to rise in incidence worldwide.Moreover,they represent a significant portion of cancer mortality in Asia and the western world.These facts have been met with some of the boldest and most important advances in cancer biology and therapy that have reshaped this field. | Edwin M.Posadas David J.McConkey Leland W.K.Chung | 2016 | Asian Journal of Urology2016，3，4： | 0 |
