Cells from 102 nasopharyngeal biopsies of patients suspected of Nasopharyngeal Carcinoma (NPC) and family members of NPC patients were cultured. Metaphases were successfully obtained from 74 of the biopsies of which 52 were subsequently histologically confirmed to be NPC. Cytogenetical analysis using Q-banding showed abnormalities in 15 cultures, and these included polyploidy, aneuploidy and marker chromosomes. Of the 15 abnormal cultures, 14 were from confirmed NPC patients and in five of these, a consistent 5q+ abnormally was seen involving 5q31. The only other abnormal chromosome changes seen was in a patient with olfactory neuroblastoma.
对102例疑似鼻咽癌（NPC）患者及NPC患者家属的鼻咽活检组织细胞进行培养。从74例活检组织中成功获取了中期分裂相，其中52例随后经组织学确诊为NPC。采用Q显带技术进行细胞遗传学分析，发现15个培养样本存在异常，包括多倍体、非整倍体和标记染色体。在这15个异常培养样本中，14个来自确诊的NPC患者，其中5个样本中 consistently 5q+异常，涉及5q31。唯一观察到的其他异常染色体变化发生在一名嗅神经母细胞瘤患者中。
原文中“consistently”这个词在这里表述不太准确，可能影响理解，我按原文翻译了，但意思不是特别明确，正常应该是类似“一致的”之类更准确表达相关异常情况的词。
