Monosomy for chromosome 9, as well as loss of heterozygosity for markers on this chromosome, has been detected in a high percentage of transitional cell carcinomas (TCC) of the bladder. We report a case of a TCC of the bladder with an interstitial del(9)(q11q21.2) that could be indicative of the presence of a putative tumor-suppressor gene related to bladder tumor progression. To elucidate the role of chromosome 9 in bladder tumors, it would be interesting to study a possible loss of heterozygosity in this chromosome region.
在高比例的膀胱移行细胞癌（TCC）中已检测到9号染色体单体性以及该染色体上标记的杂合性缺失。我们报告了一例膀胱TCC病例，其存在间质del(9)(q11q21.2)，这可能表明存在一个与膀胱肿瘤进展相关的假定肿瘤抑制基因。为阐明9号染色体在膀胱肿瘤中的作用，研究该染色体区域可能存在的杂合性缺失将很有意义。
