METHODS： Clinical features of patients with FAP were investigated. If there is any question, their medical records were verified. Blood sample was taken and lymphocyte immortal cell lines were established with modified EB-transformation methods. Congenital hypertrophy of retinal pigment epithelium （CHRPE） was checked by an experienced ophthalmologist. RESULTS： Twenty seven families including 21 classical FAP （CFAP） families, 3 attenuated FAP （AFAP） families, and 3 suspected AFAP families were investigated. A total of 116 lymphocyte immortal cell lines were established from 26 families. In all the FAP families, colorectal cancer occurred at the mean age of 42.84 years. Of the 16 families checked, 15 （93.75%） had CHRPE. The mean number of patients suffering from colorectal neoplasm was 3.14 in CFAP families and 2.0 in AFAP families （P 〈 0.01）. The mean oldest age at diagnosis of FAP was 41.75 years in CFAP families, and 58.67 years in AFAP families, respectively （P 〈 0.01）. Mean age of development of colorectal cancer was 42.23 in CFAP and 57.33 years old in AFAP （P 〈 0.01）. Mean of the earliest age at diagnosis of FAP was 29.95 years in the FAP families with a positive family history and 46.80 years in the FAP families with a negative family history （P 〈 0.01）. The ratio of extra-intestinal tumors to colorectal neoplasms was different in the two kinds of families with positive and negative family history （P 〈 0.01）. CONCLUSION： Additional use of ciclosporin will effectively improve to establish lymphocyte immortal cell lines with modified EB- transformation methods. In Chinese FAP, there was a high frequency of CHRPE, and a later age at diagnosis and a later age of development of colorectal cancer in AFAR And earlier age at diagnosis in FAP with positive family history was also found that will help to diagnose various kinds of FAP in Chinese.展开更多
目的:研究家族性腺瘤性息肉病(familial adenomatous polyposis,FAP)患者中双眼多灶性先天性视网膜色素上皮肥厚(congenital hypertrophy of the retinal pigment epithelium,CHRPE)患者的眼底荧光素血管造影(fundus fluoresceinangiogr...目的:研究家族性腺瘤性息肉病(familial adenomatous polyposis,FAP)患者中双眼多灶性先天性视网膜色素上皮肥厚(congenital hypertrophy of the retinal pigment epithelium,CHRPE)患者的眼底荧光素血管造影(fundus fluoresceinangiography,FFA)的特点。方法:我们对22例有65处CHRPE病灶的FAP患者前瞻性进行FFA和眼底检查。结果:发现86%CHRPE病损面积>0.5个视盘直径,74%的CHRPE病变接近视网膜血管,视网膜血管有以下变化:46%CHRPE病变中出现毛细血管无灌注区,8%穿过病灶的视网膜血管部分阻塞,6%出现脉络膜视网膜吻合支,3%病变有毛细血管微血管瘤,5%可观察到脉络膜毛细血管,20%的脉络膜毛细血管出现在脱色素边缘晕环中。约10%的CHRPE病变眼底检查未发现,只能通过FFA观测到。结论:虽然通过眼底检查能诊断CHRPE,但有些病变仍需通过FFA确诊,其对此病变仍是非常有用的诊断方法。展开更多
