美《医学世界新闻》第22卷第21期(1981年)报道美国达特默思消息:据宾夕法尼亚一名研究人员报告的实验结果表明,经治疗而存活下来的癌细胞不仅可以繁殖,而且有不同于原来肿瘤细胞变异株的转移能力。他在达特默思医学院八十年代癌瘤讨论会上报告说,这些变异株还可能有新的抗药能力和其他使恶性肿瘤更具进攻性的特性。宾夕法尼亚费城大学的病理学研究教授波斯特(George Poste)说,他与马利兰弗雷德里克肿瘤研究中心的菲德勒(Isaiah J Fid-ler)医生曾观察到未受到干扰肿瘤的多型异源细胞处于生态平衡状态。他们发现,杀死细胞
The United States “Medical World News” Volume 22 Number 21 (1981) reports Dartmouth, the United States: According to a report by a Pennsylvanian researcher, experimental results show that cancer cells that survive treatment can not only reproduce, but also have Different from the original tumor cell metastasis ability. He reported at the Dartmouth School of Medicine Cancer Symposium in the 1980s that these variant strains may also have new resistance capabilities and other features that make malignancy more aggressive. George Poste, professor of pathology at the University of Pennsylvania, Pennsylvania, said that he and the Iliaah J Fidler at the Frederick Center for Cancer Research in Maliland have observed undisturbed tumors with multiple types of heterogeneity. The cells are in an ecologically balanced state. They found that killing cells
