细胞动力学的研究对于探索肿瘤的发展和指导肿瘤的化疗具有特殊重要的意义。近二十年来的研究,对于逐步阐明肿瘤细胞的普遍规律已作出了很大的贡献。但是对于临床病人,更需要了解个别病人、不同病期的特定的细胞动力学变化,并依据其特殊情况制定切合于实际需要的化疗方案以提高疗效。近十多年开始在急性白血病患者中应用简易的体外氚-胸腺嘧啶 The study of cell kinetics is of special significance for exploring the development of tumors and guiding the chemotherapy of tumors. Research in the past two decades has made a great contribution to gradually clarifying the general laws of tumor cells. But for clinical patients, but also need to understand individual patients, different stages of the specific changes in cell dynamics, and according to their special circumstances to develop appropriate to the actual needs of the chemotherapy regimen to improve efficacy. Nearly a decade began to apply simple in vitro tritiated thymidine in patients with acute leukemia
