对三例原发性肝细胞癌的短期培养进行细胞遗传学分析。例1核型正常。病例2除了具有正常男性染色体互补的细胞外,还具有-Y克隆。例3中发现两个异常克隆,一个为-Y,另一个为高度异常核型:71-79,XX,-Y,(3 n +/-),+3,-8,-16,-17,-21,dez(1)t(1;?)(p36;?), del(1)(p11),+ dez(1)t(1;?)(q21;?), + del(1)(q32),+ der(3)t(1;?; 3)(3qter --> 3p11 =?= 1p12 --> 1p36 =?),der(6)t(6;8)(q12;q13),+ der(6),9p+,+ del(9)(q13),del(10)(q24),dez(12)t(12;?)(p13;?), inv dup(12)(q11 q24),der(13)t(10;13)(q11;p13),+ 1- 9三月。我们的研究结果,整理与以前发表的原发性肝细胞癌和三个细胞系中的研究结果,表明染色体1和6的结构变化,导致1 p和6 q材料的损失,以及染色体16的损失是肝细胞癌发生的常见事件。
Short-term cultures of three primary hepatocellular carcinomas were cytogenetically analyzed. Case 1 displayed a normal karyotype. Case 2 had, in addition to cells with a normal male chromosome complement, a clone with -Y. In case 3, two abnormal clones were found, one with -Y and one with a highly aberrant karyotype: 71-79, XX, -Y, (3n+/-), +3, -8, -16, -17, -21, dez(1)t(1;?) (p36;?), del(1)(p11), + dez(1)t(1;?)(q21;?), + del(1)(q32), + der(3)t(1;?;3)(3qter --> 3p11 = ? = 1p12 --> 1p36 = ?), der(6)t(6;8)(q12;q13), + der(6), 9p+, + del(9)(q13), del(10)(q24), dez(12)t(12;?)(p13;?), inv dup(12)(q11q24), der(13)t(10;13)(q11;p13), + 1-9mar. Our results, collated with the findings in one previously published primary hepatocellular carcinoma and in three cell lines, suggest that structural changes of chromosomes 1 and 6, leading to loss of 1p and 6q material, and loss of chromosome 16 are frequent events in hepatocellular carcinogenesis.
