最近,在细胞遗传学研究中发现一些类型的肿瘤病人有恒定和特异的染色体畸变。这提示在恶性病变开始时染色体改变的基础性作用。有报道大约98％的人和动物肿瘤有染色体结构和/或数目畸变,如染色体畸变率高,也具有预测价值。为了证实 Recently, cytogenetic studies have found that some types of cancer patients have constant and specific chromosomal aberrations. This suggests a fundamental role for chromosome alteration at the onset of malignant lesions. About 98% of human and animal tumors have been reported to have chromosome structure and/or number aberrations, such as high rates of chromosomal aberrations, and also have predictive value. In order to confirm
