美国癌症的死亡率和发生率依然持续增长,但令人鼓舞的是癌症患者总生存率有所提高。尽管如此,按照美国统计总署(GAO)的一项调查显示,如果更多的临床医师运用外科手术,化疗,放疗各种联合方案,癌症病人的生存率还会更高些。典型的例子是约半数的结肠癌患者手术治疗后复发,国家癌症研究所(NCI)认为,如果在术后规定用大剂量5一氟脲嘧啶来强化疗效,则这种情况将会改善。GAO调查指出,实际上94%的结肠癌病人未得到这种术后治疗。议会拨款小组根据积累的事实写出了包括用于生
Mortality and incidence of cancer in the United States continue to increase, but it is encouraging that the overall survival rate of cancer patients has increased. In spite of this, according to a survey conducted by the General Administration of Statistics of the United States (GAO), if more clinicians use surgical procedures, chemotherapy, and radiation therapy, the survival rate of cancer patients will be even higher. A typical example is that about half of colon cancer patients relapse after surgical treatment. The National Cancer Institute (NCI) believes that this condition will improve if a large dose of 5-fluorouracil is prescribed postoperatively to enhance the efficacy. According to the GAO survey, in fact, 94% of patients with colon cancer do not receive such postoperative treatment. The parliamentary appropriation team wrote based on accumulated facts including
