癌症疼痛在全球是一个普遍问题.世界卫生组织1985年统计表明,目前全世界每年新发生的癌症患者约900万,预计到2015年可达1500万,其中约有30%～50%的患者伴有不同程度的疼痛,且多数患者的疼痛并未得到有效控制.因此有效的止痛治疗是世界卫生组织癌症综合规划的4项重点之一.80年代初世界卫生组织提出了到2000年达到在全世界范围内“使癌症病人不痛”的目标.1991年4月,我国卫生部下达了“癌症病人三级止痛阶梯治疗”的有关文件.
Cancer pain is a common problem in the world. According to statistics from the World Health Organization in 1985, there are about 9 million new cancer patients in the world each year, and it is expected to reach 15 million by 2015, of which about 30% to 50% of patients There are varying degrees of pain, and most of the patients’ pain is not effectively controlled. Therefore, effective pain relief treatment is one of the four priorities of the WHO Comprehensive Plan for Cancer. In the early 1980s, the World Health Organization proposed to reach the full level by the year 2000. In April 1991, the Ministry of Health of China issued the relevant documents on “Three-stage pain relief treatment for cancer patients”.
