摘要 目的:分析神经鞘瘤22号染色体杂合子丢失(CHR22 LOH)及其与临床行为之间的关系。方法:通过变性聚丙烯酰胺凝胶、银染观察神经鞘瘤CHR22 LOH频率;通过Ki-67、PCNA免疫组织化学计算神经鞘瘤的增殖指数。结果:36例神经鞘瘤中15例发生CHR22 LOH(41.6%),发生缺失的神经鞘瘤的增殖指数高于无缺失者(P<0.05)。结论:CHR22 LOH是神经鞘瘤发生中的常发事件,缺失的区域包括NF2基因,CHR22 LOH可能是神经鞘瘤增殖的重要因素。 Objective: To analyze the loss of heterozygosity for markers on 22 chromosome (CHR22 LOH) and the relationship between it and clinic behavior. Methods: We observed the frequency of CHR22 LOH by denatured polyacry-lamide gels and silver staining. The proliferative index of schwannoma was calculated by Ki-67, PCNA immunohis-tochemistry. Results: 15 schwannomas(41. 6%) showed allele loss. The proliferative index of schwannomas with LOH were significantly higher than those without LOH (P<0. 05). Conclusion: CHR22 LOH was the frequent event in the tumorigenesis of sporadic schwannoma, including NF2 gene. The CHR22 LOH might be an important factor to affect the proliferation of schwannoma.
