肿瘤化疗已有很大进展,但目前用以治疗肿瘤的化学药物仍存在着一定的问题和缺点,如对肿瘤组织选择性不高(对正常组织尤其是造血系统及其代谢生长旺盛的组织有较大的毒性作用),抗癌谱还不够广,对一些常见的肿瘤疗效尚不够理想,因而在应用中对其可能出现的不良反应应采取适当的防治措施。不良反应表现一、血液系统:由于人体内的白细胞寿命只有4～5天,血小板9天,而红细胞120天左
Chemotherapy for cancer has made great progress, but there are still some problems and shortcomings in the current chemotherapeutics for cancer treatment, such as low selectivity for tumor tissue (for normal tissues, especially the hematopoietic system and the tissues whose metabolic growth is vigorous Greater toxicity), anti-cancer spectrum is not broad enough for some common tumor efficacy is not yet ideal, and therefore its possible adverse reactions in the application should take appropriate preventive measures. Adverse reactions manifestations One, the blood system: As the life of white blood cells in the human body only 4 to 5 days, 9 days of platelets, and red blood cells 120 days left
