Clinical Significance of Serum Assay of CYFRA21-1 in Primary Lung Cancer.

open access: yesHaigan, 1995
原発性肺癌における新しい腫瘍マーカーであるサイトケラチン19フラグメント (CYFRA21-1) の臨床的意義を検討するため原発性肺癌患者52例と他の肺疾患患者38例, 健常者22例について血清CYFRA21-1を測定し, 他の腫瘍マ-カー (CEA, SCC, NSE) と比較検討した.cut-off値を3.5ng/mlとすると原発性肺癌における陽性率は65%, 他の肺疾患における偽陽性率は8%であった.組織型別では, 扁平上皮癌で88.9%と最も高い陽性率を示し, 腺癌でも61.5%の陽性率を示した.免疫組織学的検討では扁平上皮癌において細胞質内で均一に強陽性に染色された.臨床病期別検討では, 1期50%, II期50%, IIIA期40%, IIIB期71%, IV期72 ...

Y Chromosome Haplogroups and Susceptibility to Esophageal Squamous Cell Carcinoma: An Exploratory Association and Diagnostic Modeling Study

open access: yesMolecular Genetics &Genomic Medicine, Volume 14, Issue 8, August 2026.
The exploratory study examined whether Y chromosome haplogroups are potentially associated with ESCC in a male Chinese cohort. O2a1b and O1b1a showed nominal differences between patients and controls, but these signals were not robust after FDR correction. RNA‐seq suggested possible biological differences, which require validation in larger independent

CYFRA21-1和CEA对Ⅲ期非小细胞肺癌患者的临床预后意义

open access: yesZhongguo shiyan zhenduanxue, 2007
目的探讨CYFRA21-1和CEA对Ⅲ期非小细胞肺癌患者的临床预后意义。方法采用化学发光法检测62例Ⅲ期非小细胞肺癌患者放疗前与放疗结束时血清标本中CYFRA21-1和CEA的含量,临床随访6-24月。结果Ⅲ期非小细胞肺癌患者放疗结束时血清中CYFRA21-1和CEA的水平显著低于放疗前;放疗前血清中CYFRA21-1和CEA升高患者组的2年生存率与正常组2年生存率差异均无显著性意义;放疗结束时CYFRA21-1和CEA的水平正常组的两年生存率明显高于升高组;放疗结束时CYFRA21 ...
