恶性肿瘤患者 ,以化学治疗为主要手段 ,化疗药物在杀灭肿瘤细胞的同时 ,也抑制了骨髓造血功能 ,使外周血细胞减少 ,从而易发生严重感染 ,出血等并发症。为使化疗疗程顺利进行。达到预期的疗效 ,合理使用粒细胞集落刺激因子 (Ｇ -ＣＳＦ) ,促进骨髓造血功能的恢复是至关重要的。 In patients with malignant tumors, chemotherapy is used as the main means. Chemotherapy drugs kill the tumor cells and also inhibit the hematopoietic function of the bone marrow. As a result, the number of peripheral blood cells is reduced, and complications such as serious infections and bleeding are prone to occur. In order to make the chemotherapy treatment proceed smoothly. To achieve the desired efficacy, rational use of granulocyte colony-stimulating factor (G-CSF) to promote the recovery of bone marrow hematopoietic function is essential.
