Introduction: Epithelial ovarian cancer (EOC) is the most common cause of death among gynecological malignancies. Despite surgical and pharmacological efforts to improve patients’ outcome, persistent and recurrent EOC remains an un-eradicable disease.
Chimeric associated antigens (CAR) T cells are T lymphocytes expressing an engineered T cell receptor that activate the immune response after an MHC unrestricted recognition of specific antigens, including tumor associated antigens (TAAs).
CART cells have been shown to be effective in the treatment of hematologic tumors even if frequently associated with potentially severe toxicity and high production costs.
Areas covered: In this review, we will focus on preclinical and clinical studies evaluating CART activity in EOC in order to identify possible difficulties and advantages of their use in this particular setting.
Expert Opinion: The pattern of diffusion within the peritoneal cavity, the tumor microenvironment and the high rate of TAAs make EOC a particularly interesting model for CART cells use. Data from preclinical studies indicate a potential activity of CARTs in EOC, but robust clinical data are still awaited. Further studies are needed to determine the best methods of administration and the most effective CAR type to treat EOC patients. 相似文献
Cell processing laboratories are an important part of cancer treatment centers. Cell processing laboratories began by supporting hematopoietic stem cell (HSC) transplantation programs. These laboratories adapted closed bag systems, centrifuges, sterile connecting devices and other equipment used in transfusion services/blood banks to remove red blood cells and plasma from marrow and peripheral blood stem cells products. The success of cellular cancer immunotherapies such as Chimeric Antigen Receptor (CAR) T-cells has increased the importance of cell processing laboratories. Since many of the diseases successfully treated by CAR T-cell therapy are also treated by HSC transplantation and since HSC transplantation teams are well suited to manage patients treated with CAR T-cells, many cell processing laboratories have begun to produce CAR T-cells. The methods that have been used to process HSCs have been modified for T-cell enrichment, culture, stimulation, transduction and expansion for CAR T-cell production. While processing laboratories are well suited to manufacture CAR T-cells and other cellular therapies, producing these therapies is challenging. The manufacture of cellular therapies requires specialized facilities which are costly to build and maintain. The supplies and reagents, especially vectors, can also be expensive. Finally, highly skilled staff are required. The use of automated equipment for cell production may reduce labor requirements and the cost of facilities. The steps used to produce CAR T-cells are reviewed, as well as various strategies for establishing a laboratory to manufacture these cells. 相似文献
