The main aberrations of the euchromosomes was chromosome gain, including trisome, tetrasome, and polysome. The gain rates of the four euchromo-some were 84.9%, 77.5%, 63.7% and 83.2%, and the frequencies of polysome for each euchromosome were 24.6%, 34.9%, 23.4% and 31.7%, respectively. Loss of chromosome Y was observed in 61.2% of male patients. The combination of the four chromosome probes 3, 8, 10 and 20 detected 74.5% of ESCC and the combination of 3, 8, 20 and Y detected 85.0%.

发现所测常染色体在食管癌组织中均存在较高的数目畸变率，主要表现为染色体增益，包括三体、四体及多体。4条常染色体3、8、10和20号染色体增益率分别为84.9%、77.5%、63.7%和83.2%，其中多体率各为24.6%、34.9%、23.4%和31.7%。Y染色体在61.2%的男性患者表现缺失。3、8、10和20号探针联合检测食管癌的阳性率为74.5%， 3、8、20和Y染色体探针联合检测男性食管癌的阳性率为85.0%。
