非特指外周T细胞淋巴瘤中PTEN的改变
Genetic aberration of PTEN in peripheral T cell lymphoma, not otherwise specified
摘要
Abstract
Purpose To investigate the genetic changes of tumor suppressor gene PTEN in PTCL-NOS, and to explore its relationship with the development of PTCL-NOS and other clinicopathological parameters. Methods Thirty-six cases of PTCL-NOS were studied by fluorescence in-situ hybridization ( FISH ) using interphase dual-colour probes. The probes were generated from BAC clones RP11 - 380G5 corresponding to PTEN gene. Correlation of the genetic changes with patients prognosis and other clinical parameters was analyzed. Results Loss of heterozygosity ( LOH ) of PTEN presented in 8/36 cases; Kaplan-Meier survival analysis indicated there was a trend that the group with PTEN gene change had a poorer prognosis than the group without PTEN gene change ( P < 0. 05 ), but there was no correlation of the gene alteration with tumor stage, site, age, sex and LDH level ( P >0. 05 ). Conclusion A significant percentage of PTCL-NOS carry the genetic alteration of PTEN that may play an important role in the pathogenesis of PTCL-NOS and the e-valuation of the patient' s prognosis.关键词
