In order to find out the genes involved in the tumorigeneais of laryngeal carcinoma,we analyzed 18 laryngeal car-cinoma with comparative genomic hybridization. Results show that each one has different degree of variances,included gains and losses of partial and whole chromosome. Each case has 12.9 abnormal regions averagely; losses are more than gains, equal to 7. 2 and 5. 7 per case respectively. Main regions are gains in chromosomes 3q(78% ) ,5p(61% ) ,llq(56% ) ,lq (50% ) ,8p(44% ) ,8q(39%) and 15q(39% ) ,and losses of 3p(70% ) ,5q(78% ) ,9p(67% ) ,13q(50% ) ,lp(44% ) and 14q(39% ). There are many specific gains and losses in several chromosomes, especially the increase of copy number karyotype in Ipl3-21 (8/18 ) ,3p21-23( 14/18) ,5p21-22( 14/18) ,9pl2-pter( 10/18) and 13q21-31 ( 8/18 ), while the de-crease in lqll-21 (11/18) ,3ql5-21 (12/18) ,8p22-24(6/18 ) , Ilql2-13 ( 8/18 ) , 15q21-23 (7/18 ) fP 18pl 1(8/18) are the characteristic varieties. These results suggest that there are oncogenestumor suppressor gene and other associated genes involved in the tumorigenesis. |
